' (>orge Blaisdell and his family own . Zippo Manufacturing Co., in Brad1 .,] Pa. The company is known for the j u,ui. windproof Zippo lighter, the !,..l-known product of its kind in the (llii. Presidents, kings, world statesn. military men and women, corpor(t, lu-ads. and millions of others all ,r the world, own Zippo lighters, flu- company produces 33 models of p,,htcrs. ranging from S4.75 in brushed (prome to S560 in 1-1K gold. Its basic line consists of two standard sizes: a .Inn model, that is about 114-in. wide jnd 2*4-in. high: and a standard model that is approximately lko-in. wide and _prin. high. According to Ray Ihler. Zippo's plant manager, tin lead solder plays one of the most critical roles in the efficient manufacture and operation of the fault ier lighters. He savs this is why the -oidering operation includes very string ent quality control procedures. Uhler explains that solder preforms iiterallv help put the "zip" in Zippo lighters. The preform is used to solderjoin and seal a plate to the inner case i; the lighter. W hen this case is inserted mtn the outer shell of the lighter, the rr-uiiing en\elope forms a sealed enclo sure that contains the wick and the ab sorbent packing to hold the fluid used to fuel the lighter. Therefore, the sol dered plate must form an airtight and leak-proof seal with the inner case. Otherwise rapid evaporation would waste the fuel and require too frequent reidling. All solder preforms used in the join ing process are 50/50 tin lead alloy. The preforms vary in length and width, depending on whether slim- or regulardze lighters are in production. Regular-izt preforms are ,015-in. thick, while the thin -size preform is .017-in. thick. The thickness variation is due to the difference in gauge of the stainless steel Used for the two cases--.015-in. for the slim case and 0.018-in. for the regular case. About -iO'i of Zippo's sales volume comes from more than 27,000 commer cial accounts, comprising some of the biggest corporate names in industry. They regularly order Zippos in huge lots to serve as premiums, promotional handouts, employee awards and sales in centives. Many times the company em blem is soldered on the face of the lighter. "If you solder an emblem on. you know it's going to stay." savs plant Manager L hler. "If the emblems are epoxy-joined to the face of the lighter, you know that sooner or later, they will come off. We've tried other joining tech niques. too. hut we always come back to solder because it's the best and most economical joining method we've found. He also points with pride to the fact that feu of the thousands of lighters the Zippo repair section processes each day irnolve resoldering. Some bear the ravages of having been soaked in sea water, buried in snow or embedded in mud. Others have been mangled by washing machines, hydraulic presses and lawn mowers--and a few stopped bullets in World War II, Korea and Vietnam.

After proof firings with black powder, the guns will be mounted on carriages built out of solid oak in Glens Falls. N.V. by Adirondack Machine Corp. Some of the carriages are heavier than the guns they carry. Authentic even to the blue-grav paint that typified British Army weaponry of the period, the carriages were designed after exhaustive study of old paintings, draw ings and other records. W illiam E. Meuse, chief of historic ordnance of the National Park Service, is in charge of the project. The original cannons were designed and manufactured in Europe. A few guns were cast for the patriots bv foundries located primarily in the Phil adelphia area. The most notable of these was one operated bv J. Byers, who turned out pieces equal in every respect to the finest that England's Woolwich arsenal could produce. Mostly, however, the Continental Army relied on acquir ing cannons from French or other Euro pean foundries, or on capturing British artillery. Sound enclosure softens punch of press noise Industry face? heavy pressure today to comply with the noise control regu lations of the Occupational Safety & Health Act I OSH A i. When it come? to Generating excessive industrial plant noise, automatic punch presses are among the leading offenders. So when a company like Associated Spring real izes a 17 db reduction in such machine ry noise, it can he credited with quite an accomplishment. It can roughly he compared to paring down the painfully loud noise of a riveting gun to the sounds of city traffic heard from within an automobile. The company's Dayton.

After investigating production flow, equipment maintenance, and machine accessibility, the consultants recom mended a sound enclosure system for one of the two -15-ton presses that proved to be the principal sources of excessive noise. The press produces metal washers from 26 gauge strip steel. 24'2-in. wide. Made by Singer Partitions of Chicago, the enclosure is constructed of lead/ vinyl curtain material combined with Tin. thick Mylar-covered acoustic foam panels applied to the inside curtain sur face. W ith the My lar covering, oil splash and metal trimmings cannot clog or de stroy the foam. The lead-loaded vinvl ;heet specified was 0.75-lb./sq. ft. This dense, limp material provides the neces sary mass with flexibility and it is a highly efficient sound barrier. The enclosure measures 10-ft. x 10-ft. gizes the control circuit, rendering the press inoperative. Before the sound enclosure installa tion. the noise level reading was 101.5 db. despite the installation of vibration isolators to decouple the press from the lloor. This compares with a post-enclo sure reading of 84.5 db. The 17 db at tenuation achieyed. without sacrifice in production capacity , cunyinced the com pany to install a similar enclosure tor the second offending 15-toil press. Tom Campbell, diyisimi manager, noted that the noise reduction exceeds present O.SHA requirements. And should a currently contemplated lower standard of 85 db be put into effect, the company would still be within compliance limits. "We were especially pleased to note inJmediate workers' acceptance of this new system as an improvement to their en vironment and safety." Campbell said. ost people know that lead plays a M vital role in the design of yachts lead used as ballast in the keel keeps -acht upright in the water. But few ^ople know that lead is also playing ^ ,'mDortant role in the design of golf an lnir 1 lead in a golf iron? Simply (e(j it provides the concentrated eialit that's needed in the newer, lightjdht irons to give them extra driving jiowcr. although the use of lead in golf irons p not new. the traditional wav to add concentrated weight for golf irons was to load the inside of the shaft with chunks of lead near the point w here the head is attached to the shaft. This tech nique adds deadweight that has been re ported to cause problems in achieving a smooth sw ing. Shamrock Golf Co.. Los Angeles, has taken an approach that it hopes will overcome the deadweight problem. Their solution is to move the lead weight from the base of the shaft to a special spot inside the clubhead. The concept is re ported to not onlv work, but to improve the performance of the iron as well. According to Shamrock, their method makes the overall weight of the iron less. Jack Nicklaus in a recent article in Golf Digest is quoted as saying: "Dis tance is a problem for both seniors and women, and 1 think there are two rea sons. The first lies in equipment. I've increasinglv favored 'light-swinging' clubs as I've got older, and I think I'll so more and more in that direction in the future. One reason is that clubhead velocity has twice the value of mass in terms of distance--the lighter the club, the easier it is to swing through the ball fast. Also, the lighter the club, the less it takes out of you physically to swing it. This can be a big factor as one tires towards the end of the round." Called a Power Pocket, the lead weight lowers the center of gravity and places the heaviest part of the clubhead below the center of the ball. Shamrock says its long irons using the lead weight give the high, arching flight of a five wood, while short irons using it give more bite. shamrock reports the improved tech nique is more time consuming and ex pensive. but it results in a higher quality product with improved precision. The first step in producing the head is to cast the basic head of the golf club. The faceplate is then stamped from the same type of metal and it is joined to the clubhead bv electron beam fusion, a process that fuses the two metals to gether to become one homogeneous piece of solid steel. In the next step, the desired lead weight is dropped into the bottom of the cavity directly in back of the face plate. The weight of the lead depends on the type of club being produced and the swing weight desired bv the golfer. Swing weight is the relationship of the weight of the head to the length of the club. Shaped somewhat like a piece of chewing gum and ranging in weight from 2 grams to 23 grams, the lead weight is held in place with black epoxv. Lead puts clout in the clubhead uture eale? uf battery-powered in Fdustrial trucks and personnel car rier?. are likelv to stem from three major factors: On-going improvements in electric \ chicle batteries and power svstems.

It is particularly important to follow the instructions contained in any one of the various reloading manuals available at any hunting or sporting goods store. Particular care should be taken to start with the lowest recommended charges listed for each load in such manuals. There are literally dozens of shotshell reloading tools on the market. They range in price from a S9.95 pocket-tvpe outfit that reloads a box of shells in an hour to semi-automatic equipment that can produce nearly 500 shells per hour. The a\erage shooter's needs can be ade quately met by tools in the S45 to $85 price range. All of them are self-con tained units that can load three or four boxes i 75 to 100 shells I per hour. The first step in reloading of a shot gun shell is to select a clean, fired case in good condition. The cases must be stored by make--Remington. ^ inchester. Federal, etc.--and type--12. 16 and 20 gauge, because of reloading require ments. Both plastic and paper shells are abundant, but care must be taken to adjust tools to handle them. For ex ample. target loads contain light charges of shot and powder and are loaded in "high-base, permanent-wad" cases. Hunt ing loads, on the other hand, use heavy charges and are assembled in "lowbase. permanent-wad" cases of greater internal capacity. Before loading, check to make sure that all cases are carefully inspected. Cases that hare been mashed flat, seri ously deformed, or torn, should be set aside. Basic components needed for reload ing begin with standard domestic "bat tery cup" shotshell primers that are available in several makes. All makes are good and all currently produced 12 gauge shells take No. 209 size. The best wads are the one-piece plastic wad column shot-cup type. Different cases have different height wads and all deal ers hare charts telling which is correct for a particular case. The lead shot is the same no matter who makes it. Size No. 9 is usually chosen for target loads. Safety precautions are of critical im portance in reloading. Some of the pre cautions are obr ious--one should al ways wear safety glasses, never load in haste, and never smoke in the area. Primers should be carefully handled since they are the most hazardous of all components used for smokeless pow der loads. It is also vitally important to keep powder and primers away from heat, sparks and open flames. Powders should never be mixed and all shells must be carefully examined to insure they are in good condition before using. Though it must be accomplished with utmost care, reloading is simple. In the first step of a typical operation, the shotshell case is placed in a tube. At the bottom is a de-capping punch which pushes out the old primer. A downward movement of the tube seats the new primer. After it is seated, a carefullyselected amount of powder is passed into the case via a hollow tube. A wad is then inserted in the case atop the powder and lead shot is next passed into the case and seated in a similar manner. A pressure gauge at the base of the de vice shows the exact wad pressure. A cap-like die device with grooves inside is then placed over the case and, when SHOT the device is turned, the resulting folds creases in the shell. In the finished shell, the wimps. folds, should be tight and smooth, wj no noticeable springback. and with most a very small hole at the cent^ where the folds meet. Neither shouuS there be any overlap or crumpling 0{* the folds at the center. The latter cates too much case above the shot, the former too little. Adjustment of either wad column heiuht or shot chare weight is the proper corrective action. The center of the crimp should recessed nearly 1/16-in. below the rim This is necessary to avoid having the crimp loosen under recoil forces. The walls of the shell vase also should be checked to see if they have buckled due to too much crimping fore 1 Occasional minor crimp imperfection* cannot be avoided. >uch shells should! be fired first. Thousands of amateur skeet and tra^f shooters who burn up several hundredfl shells each week, are using "pack yomy own" reloading techniques to add djjj mension to their sport and--most i: portantlv--to make it as economical possible. Lead enhances organ sound at New York's Lincoln Center ,d .1 Hoy pia vs a vital rule in th>^ j.erfurmam e ol mie ol the nation's concert hall oruans.

Switzerland, are arranged in 85 ranks, distributed among 61 speaking ips. The console has four different mdependent manual keyboards with di rect mechanical linkage from the keys to the pipes. The skill that went into designing the lead alloy pipes and the patience that went into construction of the organ have been rewarded in the rich, brilliant tones that are produced. These were also achieved by subtle ad justment of pipe scale and voicing, according to Lawrence Phelps, who served as Lincoln Center's consultant for the project. Phelps helped plan the tonal design and voicing, and the slop-control and combination systems were created bv his Erie. Pa. company. 'T feel that this is the finest instrument of its kind in New \ ork. and among the top dozen in the l nited States." he stated. "It's the re sult of 100 years of deep insistence on craft." Although the organ is a product of traditional construction, modern tech niques were not ignored.

Without economical energy to provide electricity and heatins. buildings become uneco nomical to own and operate unless the added expense for energy is absorbed in higher prices for manufactured products, and increased rentals for office space and housing. One solution for supplementary elec tric energy needs is solar power from on-site sources. Incorporated into the total design or redesign of buildings, it is being stored in lead batteries from two solar sources--sun and wind. Such energy sources, when combined with these batteries, can provide much of the electrical energy required for tomorrow's buildings. A look at developments under way today shows how this might be ac complished. An excellent example of how such solar power sources can be combined ls a project now underway at the Research and Development Institute 'REDE i in Providence. R.l. REDE is the prime mover in establishing the Rhode Island Energy Conservation Sta tion ( RIECS i. which is to be housed in a recycled brass factory building originally built in the 1840 s. RF.DE is assembling a w ind and sun solar energy package that will provide for most of the building's heating, hot water and electrical needs. In addition, a miniature hvdro-electrir power plant to be installed in a small river that runs alongside the building will provide some electrical energy for the renovated structure. REDE's basic concept is to generate electricity from the wind and sun sources and store it in a large bank of lead acid batteries. The batteries are a kev element to the REDE concept. REDE will utilize solar cell semi-con ductor devices which convert light di rectly into electricity. The best known of these devices is the silicon solar cell. Solar cells themselves have no storage capability. They generate only while ex posed to light. Since the power is usu ally required continuously, lead storage batteries will be used to store power that can he used during the time the solar array is in darkness. During the daylight, the array charges the batteries and handles the electrical load require ments. A multiple battery storage fa cility will be installed in the basement level of the RIECS building to store electrical energy. The lead batteries will be installed in such a manner that they can be vented through a basement level window on the river side of the build ing. Present plans call for installing ap proximately 50 batteries to collect en ergy from all three electric generation sources scheduled for installation. Ad ditional batteries can be installed as needed. It is significant to note that the combined solar cells and wind genera tors will help to insure that the batter ies are constantly being charged. Two wind generating devices will also be installed in the RIECS building. One is a Darrieus wind plant that looks much like a giant egg beater, while the other is an improved version of the estern-type w indmill that is commonly found on farms LlA2t753 hen miners needed a serviceable Wmaterial for pants to wear pros tions, premiums, design incentive awards and gi\ e-aw avs. pecting during the gold rush of 1819 Company president John 51.

Whether constructed from ready-made or one s own design, a trouble- ,ome part of assembling such furniture joining certain parts with an adhesive, ppis step requires a reliable means of pelting pressure on the parts until the j,onding process has been completed. The pressure can be applied with a variety ,{ damps, but sometimes the furniture jcsistn calls for adhesive-bonded com ponents that are too big to accommo date clamping. Possible damage to the airfare of the parts involved is another nmsideration. A resourceful upstate New 'torker laced this problem when constructing a roffee table of his own design. He re- -orted to a product used for another jioLd'V. skeet shooting, to apply the pres- -ure normally supplied bv furniture clamps. Simply stated, he "took the lead ait" of skeet Hiouting to hold the table components in position until the bond ing agent cured. The table was designed with an oak inlav top. over a plywood base, with tun sets of -l-in. thick oak legs. The bit. \ 2-ft. top was covered with 400 Underside ot coffee table with oak legs secured by lead shot. These "clamps" were also used to hold trim around the edge of the table while it was being glued in position. oak tiles, approximately :!4-in. x 3-in., all carefully organized and glued in an intricate pattern. As a result, there was no suitable clamping surface to bold the legs against the underside of the table during the gluing process. The use of wood or metal type clamps would mar the highly polished surface of the tiles and oak legs. It was at this point that the furniture maker derided to try lead shot, a pro duct of his skeet shooting hobhv. These pellets, packaged in cloth bags of 25-lbs. each, are used to reload shotshells. Here was an excellent source of concentrated weight in a soft flexible form that would not damage the wood surfaces. With two 25-lb. bags of lead shot positioned on each of the table legs, the gluing job was accomplished without rni-hap. The lead shot has since been used ful filling 12-gauge shells for the skeet shoot ing and hunting season. However, addi tional bags are always on band to piovide lead shot "clampina" for future gluing jobs. Handmade furniture de.-iuners who are not hunting enthusia't- will find bags of lead shut readily axailable at most sporting good' stores. A one-time investment in lead shot can solve many "sticky- gluing problems similar to those encountered by the New York hunter furniture builder.
