The Battle of Hostings, authentic In details so far as historic research can reveal, was modeled for the New Jersey Museum by Greer. There's something about a soldier There are two approaches to play ing with lead soldiers and most of us gave up after exploring the first one. This was the childhood pastime of maneuvers on the living room rug to the accompaniment of "BANG, BANG -- no fair, I got you!" The second approach appears to be considerably more rewarding, but it demands skill and patience and an in terest deep enough to lead to serious historical research. This, of course, is the avocation of making scale replicas of famous soldiers of the past. In making such a figure, the work starts long before the model maker melts his lead. First he must learn the physical characteristics of the soldier he'll depict. He checks into social customs, fighting methods, standard equipment, and the uniform and colors of the regiment. \\ hen the data is complete, eight to ten hours of skilled work are needed lo build tlie figure. There is no stand ard method in doing this -- the degree of complexity and the peculiar details required determine the technique. Master Sergeant William E. Greer, who made the miniatures pictured here, often starts by cutting a cruci form blank from sheet lead. This is bent and built up with solder or metalfilled plastic as needed. Careful filing and shaving bring the model to the final dimensions. Of course, the details of dress and equipment are just about impossible to sculpt in this way. Belts, buckles, blanket rolls, cap ornaments, helmets, heraldic devices, flags, gun barrels, cloaks, capes, and sashes are cut from thin sheet (lead toothpaste tubes are a favorite source) and cemented to the figure before it is painted. Sergeant Greer's collection of tools for this task is just as specialized as any plumber s or sheet metal shop's: dental probes, evebrow tweezers, sewing machine needles and mimeograph stencil styli. Among his heavy equipment is a light soldering iron and a bean can he uses for a melting pot. Makers of miniatures prefer to use lead because its malleabilitv allows them to drape a cloak or bend a figure to take a position which fits the action. Thev like lead's durability and the fart that it can he melted and remelted, as Sergeant Greer puts it. "with a mini mum of fuss and equipment -- in the kitchen or home workshop."

Since retainer ring comes assem bled on barrel, the gasket and lead lock ore the only loose accessories. As each joint is made, barge moves ahead allowing pipe to slide down the chute. A FLEXIBLE PIPELINE OF When a pipeline crosses a lake or stream, there are two traditional solu tions to the problem of rigid pipe versus the irregular bottom contour: suspend the pipe above the water or carefully excavate a straight level trench underwater. Both are touchy undertakings. Both are costly. And anv skimping with either procedure is likelv to result in a costly leak. Happily, there is a way to make cast iron piping flexible enough to fit such contours. Last Year Lnited States Pipe & Foundry Company introduced Usiflex boltless flexible joint pipe. This type of pipe is unique because it can be assembled without the use of bolts, nuts and wrenches, and is posi tively locked against pull-out. The joint is of the push-on type where the water tight seal is made by compression of a gasket between the spherical ball and corresponding spherical surface in the bell. The joint can be deflected as much as 15c and still remain bottle-tight. Several recent installations poi the advantage of this novel pipe, f the Long Island W ater Corp. pipe water service across the I age Canal near South Baldwin,] for example, the job was done i duced cost with 16" Usiflex flexible joint pipe.

Boost Machining Speeds Lead and tellurium are making news again! In recent months, lead telluride has been spotlighted as its thermo electric properties have become better known. Now the spotlight has shifted to a new use for the two metals -- a fast cutting leaded steel containing small amounts of tellurium. Recent tests by the La Salle Steel Company of Ham mond, Indiana, a leader in the develop ment of free-machining leaded steels, have proved that the addition of tellur ium to leaded steels increases their machinability even further. Using hexasonal 13 16-in. stock (photo) and first class machinerv, cut ting rates for La-Led X 35 to 40 per cent higher than regular leaded steels and 31/-; times the rate of or dinary steels were easily achieved. Though its price is slightlv higher than regular leaded steel, its greater machining speed could easilv offset this factor, since in this type of opera tion millions of pieces are produced each year and the cost is figured on a unit basis. Thus if a second were saved on each part, two working days of ma chine time, labor and overhead could be saved for everv 60.000 parts pro duced.

Forty years of engineering progress have changed the picture -- the cable link was completed this winter. More than 70 miles of cable have been laid across the channel, joined, and connected to the [rower networks of the two countries. Since peak de mands in England and France occur at widely differing limes, each can act as a power reserve for the other. The cable makes it possible to transfer ] 60.000.000 watts of power in either direction. Though each of the two countries uses a 50 cycle alternating current standard, the transfer link is a direct current loop. There are two reasons for this. In the first place DC makes it unnecessary to phase the two sys tems exactly. Severe overloads would result from improper phasing or synchronization. In the second. DC makes the maximum use of the insula tion value of the cable. For the same electrical stress as the 100 kv employed in DC transmission. AC transmission would have been restricted to 70 k\. Based on this design concept, the completed link uses two single-conduc tor cables sheathed in lead and ar mored with galvanized steel wire. One of these is operated 100.000 volts posi tive with respect to ground: the other 100.000 volts negative with respect to "round. Because of the excellent cool ing effected by the surrounding sea. water, 200 amperes may be carried without heating. Precise engineering details of the cable have not yet been released by Britain's Central Electricity Generat ing Board, but it is estimated by re liable sources to have an overall diameter of 3f 4 inches with the lead sheath being 1:,4 inches OD and 0.1 inch thick. The cables weigh nearly four tons per 1000 y ards. Details of the French half of the link were not available. The advantages of lead sheathing for this sort of cable service are well known. Lead maintains watertight in tegrity which, in turn, permits the use of paper insulation. This is highly preferable -- one might even sav necessary -- for reliable service in the voltage range required. \\ bile other metallic sheaths might also provide 1 watertightness, none of them has lead's flexibility or immunity from corro sion in service. aanwunro'Hitfti Battery Power Mans the Pump Boat owners, campers and all others who need running water in unlikely places (including flooded basements) now have a pump of unri valled convenience. Powered by two 2-volt leadacid cells, it moves three gallons of water a minute and will run seven hours without recharg ing (by plugging into a standard 110 volt outlet). Life expectancy for the batteries is four years. This is one of a series of battery-powered products planned by Russell Harrington Company of Southbridge, Mass. i  ^jt issue, LEAD looked into Ignition systems for f urnaces, pedometers, and scales soon to be Braking use of the piezoelectric magic of lead jlrconate titanate. This issue describes electrostatic filtering for home air conditioners and the possibility of a "picture frame" TV tube. TV "tube" of the future Is not a tube at oil but a sheet made up of layers of transparent conductor, electroluminescent ma* teriai, non-linear resistance and lead zirconate titanate. Simple images like the circle shown have demonstrated the potential of the "tube" to produce pictures. The unique performance of FZT as ( producer of high voltage whenever it it mechanically stressed has already won it a host of interesting jobs. Among those now under serious study or about to be produced commercially *re high voltage generators for air conditioners, room air purifiers and range hoods. Electrostatic air filtering on these appliances is known to be the best approach -- but conventional means of generating the voltage is just too expensive to be considered for wide-spread use. A transformer, capacitors and a rec tifier are required to keep a high static charge of electricity on the air filtering screen. All this equipment adds dollars to the cost. Inventor Jerome Murray's s\stern is simple and costs less than S2. Pres sure from a cam on a piece of PZT no bigger than the tip of vour little finger is all that is needed to supply 6000 volts at 1 milliampere. (His arrange ment. in fact, can supply 21.000 volts.! The electrostatic filter so produced is about 90 per cent efficient compared with about a 20 per cent efficiency for the mechanical filtering system it re places. The photos of the unit were taken at the labs of The Jerome L. Murray Corp., 401 East 58th Street. New York 22, N. Y. A flat TV set that will hang on the wall like a painting may be a reality one day. Recent experiments at Gen eral Telephone and Electronics Labs in Bavside. N. T . make this seemingly unlikely gadget a distinct possibility. Researchers there have developed a flat panel of PZT sheet stock coated with an electro-luminescent phosphor that will create a simple image. As in a conventional T\ tube, the image is 6000 volts from a minimum of hardware. This basic setup will be used in room oir condi tioners. The voltoge shown arcing in this dem onstrator (lower left) is produced when cams on the existing fanshaft nudge small blocks of PZT. Seporate sources of 6000, 4000, and 2000 volts will supply three filter screen elec trodes to knock out virtually all oir-borne dust and pollen. Inset shows size of the PZT unit. produced by modulating a "spot" of light that traverses the panel. Acousti cal waves interacting with the electro luminescent phosphors produce the "spot". Position is controlled by tim ing the acoustical waves and the spot is modulated by an electric field ap plied to a conductive laver over the phosphers. Some problems still exist but the feasibility of an image on a flat panel has been demonstrated.
