Ver moisture necessary for the gardens. mont. and designed by architect The public baths of the ancient Miriam Hilliard Flick as a Climate Romans were often completely lined Control Study. The purpose of this with sheets of lead, a fact which con project is to combine the advantages tributed much to their present state of new materials of construction with of preservation. Today, with modern the latest design in order to cope best advances in design and materials, with climatic conditions in a specific lead has remained an important part part of the country. of architecture--adding beautv while Lead, one of the first metais to be at the same time safeguarding against used in architecture, boasts a back the ravages of weather and moisture. ground of thousands of years of suc Weather conditions in Randolph. cessful applications under all sorts of Vermont, are severe. Temperatures climatic conditions. The Hanging hover below zero for many months while in the summer burning sun pro duces temperatures in the nigh ex tremes. Snow, sleet, rain and high winds add to the rigorous demands of nature in this area. Lead was chosen by architect Flick both because it could provide eco nomical and dependable protection against seepage and damage due to water and snow and for its aesthetic contributions. A lead lacing strip around the entire roof and turned back over the roof prevents water from entering the roof edge and forms a gravel stop. At the same time the pleasing grav patina of the lead con trasts with the natural cypres? finish First duty of the lead lacing strip shown in closeup here is to prevent water from entering the roof edge. Secondarily, it serves as an effective gravel stop. Skvdomes over kitchen and bathroom are to permit hoods of light.

The gray patina of the lead strip offers a pleasing contrast to the natural cypress finish below. and adds to the attractiveness of the design. This decorative crown of lead where the Hat. straight form of the roof meets the sky has a most pleasing color relationship to the wood b"!ow and the blue above. The satinv gray coloring recalls the effect created by a row of pewter plates in front of a panelled wall so often found in eariv .New England dining rooms. Similarly, two lead chimney caps, whose primary function is to prevent breakdown of the mortar and weather damage to the chimneys, serve also for contrast, pre senting a wide band of gray color between the red brick and the blue of the sky. The lead is used as an accent motif defining the silhouette of the building in preference to a metal which would have approached the wood in color. The rest of the lead used in the Randolph home is in the form of Hashing. A natural stone retaining wall is Hashed with sheet lead where it joins one of the roofs. An elevated level of the house is flashed with lead where it meets the roof of the lower level. The plexiglas sky domes, letting lisht into the kitchen and bathrooms, are flashed with lead and all of the vent pipes for the plumbing system are Hashed with lead. Two thousand nine hundred pounds of 3-lb. hard lead (6 percent anti mony) and 43 lbs. of 6-lb. soft lead were used in the Randolph house. Lead was used for a number of rea sons: Its unexcelled durability makes its ultimate cost extremely low. Ease of Installation and the fact that it does not cause unsightly stains or discolora tion on adjacent materials adds fur ther to its appeal to architects. Its pleasing gray color, which does not change with the years, blends well with practically any color scheme and it is highly resistant to corrosion by the elements. In fact, lead is often used in seashore residences because of its proven resistance to the cor rosive effects of-sea atmospheres--one of the severest types of atmospheric exposures, so far as metals are con cerned. Though far removed in time and distance from ancient Babylon, the new home at Randolph. Vermont, serves as an excellent example of the long recognition enjoyed bv lead in architecture and. furthermore, demon strates the versatility of lead -- the ancient metal that belongs to modern industry. The importune nuitter of chimney protection is prodded by a lead chimney cup. A iron me and the actual installation of one of two chimney caps fur the Vermont house arc shoun belou:.

On an other job. the contractor estimated 500 hr. for drilling and bolting of straps but bv using the stud driver the companv was able to reduce this time to onlv 150 hr. Operation of the stud driver is ex tremely simple and sate and does not require a skilled operator. The proper stud for the job i simple nail-tvpe. break-off head type, or threaded, each in suitable length! is selected and inserted in the end of the cartridge (of whatever driving force required).

They obviousiy are not recommended for penetrating cast iron or specially hardened steel. In a typical strapped sheet lead line steel vessel, the use of the stud driver eliminates the drilling of the strap and shell, an operation requiring about 12 min. after marking, and the set-up operation which takes about loading the gun and shooting the rivet after the set-up, making a total of only 4 min. per hole, a time saving of more than 70 percent. Furthermore, mark ing time can be cut down considerably because in driving studs it would not be necessary to adhere to a specific spacing. They could be driven vir tually at random.

The use of supervoltage X-ray does not replace me dium voltage therapy in the majority of cases, but patients for whom supervoitage therapy is indicated derive advantages from these well defined, penetrating X-ravs that are not ob tained with conventional X-rav equip ment. The deep therapy room is on the ground level of the Swedish Hospital and has walls and ceiling of concrete up to 4 ft. thick. The entrance to the room is a 4 ft. x 7 ft. opening in the concrete. To effectively seal the aper ture from stray radiation a unique lead door was designed. Measuring 6 ft. x 9 ft., the door was constructed by joining to each side of a 1 in. mild steel plate a sheet of lead 34 in. thick. In turn, the lead was covered with a 3/16 in. steel plate. Since the weight of the door then totalled 9.000 lb.. it was designed to slide on a 90 lb. railroad rail. Power operated bv a 3'4 h.p. motor, the door rolls on stand ard ball-bearing pillow blocks at a rate of 4 ft. in 20 secs. The leading edge of the door is. of course, pro tected with a safety device to prevent anvone being caught as it closes. In ase o' power failure, the door can be hand operated. The door was de signed bv G. A. Pangborn. consulting engineer of Seattle and built by Pacific Steel Products Co., also of Seattle. Behind the machine is the control room where the operator looks through glass that could almost be called trans parent lead, since it analyzes 75% metallic lead by weight. This remark able glass, called Hi-D and developed only recently, is endowed with a high refractive index, permitting extreme wide angle viewing, and exception clarity. The high density glass is most as heavy as steel, weighing abo> 390 lb. per cu. ft., w hich is 2% tinn as heavy as ordinary window glas Its radiation shielding value is oiv half that of metallic lead. indows c to 2 ft. in thickness have been mac from Hi-D glass, which is made bv th Penberthv Instrument Co.

A I iu. diameter lead shield, weight n 1700 lb. surrounds the X-ray soun at the base of the machine, and in eludes two sets of 3 in. thick lean-bric> shutters which shape the X-rav bean to be directed at the patient. Thesbricks are easily adjusted in positior by finger-tip control. Red lead Primers For Oil Storage Tanks THE oil storage tanks of Hess Inc. in Perth Ambov. N. J. are subjected to the rigorous environment of heavilv industrialized area plus a sea air atmosphere. Protective coating of the equipment puts exacting require ments on the paints used to withstand successfully the dual corrosive condi tions which are in addition to the ordi nary effects of weathering.

TT-P-86a. Type II. The job was then finished with a top coat of aluminum paint. Particular benefits result from this svstem. Excellent wetting is achieved with the first coat of Type I. which is a straight red lead-linseed oil paint. Ev en over rusted surfaces this charac teristic will implement a first line stop page to corrosion by the red lead pigment. The second coat. Type II. which is a red lead mixed pigmentaikvd varnish-linseed oil paint, is a faster drying paint which allows quicker recoating and consequent re duction in scaffolding time. Addi tionally the different color of the Tvpe II paint provides a contrasting color a Mewly painted oil storage tanks of Mess Inc. at Perth Ambov. .V. /.. de pendably protected with red lead. to aid in the avoidance of painting holidays. Choice of the top coat then depends on the job in question. Sometimes it will be merely a matter of color prefer ence, sometimes a question of heat absorption mav have to be considered, or sometimes a special condition with special requirements will obtain. Whatever the case, the job of cor rosion inhibiting primer will be well done by red lead. The formulations of the two red lead primers used on the oil tanks follow: --0 XT.

Whenever the houses were ready, so was the plumbing. Time and money were saved not just by the elimination of delays but also by the inherent economies of mass produc tion. But the advantages of lead do not stop there. When the fittings are set in place on the job. the flexibility of lead easily provides compensation for structural variations both on the spot and in the future when settling and other factors are likely to cause stresses in the plumbing that could mean trouble. Beck-Utah Co. of Dallas. Texas, is the builder of Raynor Hills. The piumhing contractor is Waldo Plumb ing & Heating Co. of Kansas Citv. Mo., and Phoenix, Ariz. Two hundred of the two and three-bedroom units in the project were completed between Sept. 1, 1953 and Feb. 1. 1954.
