Such pans have proved to be an adequate and economical insur ance against damage to materials stored below as well as to structures and decorations. A recent article in this publication described a large lead pan in a plating works in Detroit. Two large lead floor pans have been installed recently in New Y ork s Grand Central District within one hundred yards of each other. One of them under part of the kitchen and the dishwashing room of Thompson ? Restaurant in the Grand Central Ter minal building was placed early in Mav of this year. The other which is under the soda fountain in the W halen Drug Store at the corner of 42nd St. and Yanderbilt Ave. has just been completed. These two lead pans are similar to Completed lead pan under restaurant kitchen. Idle bleeders in place and lead sleeves around penetrating pipes. Asphalt paint uill be applied before slab is laid.

There are condition? in all types of buildings which create potential leakage hazards. Kitchens, toilet rooms, air conditioning rooms, la boratories and any other areas where water is used in quantity should all be carefully considered as possible sources of trouble which can be averted by use of a properly installed lead floor pan. Sheet lead by reason of its easy adaptability to the shape of its location is ideal for this purpose. --2-- LIA25908 Lead Cooling Coils In Anodizing Tank To Handle Direct Expansion Refrigeration N interesting and unusual ap- carried up over the top of the tank Ak plication of lead pipe coils is where it is welded to a steel pipe shown in the accompanying photonipple for connection to the suction graphs.

The outlet end of each coil is con nected to a 3-in. lead pipe suction header closed at the bottom. Ex tending down inside the header to within 3 in. of the bottom is a l^o-in. lead suction pipe bushed and welded at the top of the header. This pipe is as the cathode of the anodizing cir cuit. In addition a ventilating hood of 3 16 in. lead will be built over the tank to dispose of acid vapors gen erated by the process. The tank is 3 ft. 10 in. wide by 9 ft. 1 in. long by 3 ft. 6 in. deep. It was designed and installed by Reli ance Refrigerating Machine Co. of Chicago. All of the lead work, both tank lining and coil, is constructed of tellurium lead. All seams in the lining are welded and the coil sup ports are welded to the coil at each intersection. The coil is placed well out from the walls of the tank to al Opposite end oi tank showing lead lining and manner of supporting coil. -- 3- low free circulation of the solution. Agitation will be provided by three perforated lead aeration pipes. The use of lead pipe for an expan sion chamber for a refrigerant gas is unusual but perfectly feasible if the suction pressure is not excessive. In the case of freon operating at 40 to 50CF the suction pressure will probably not exceed 50 lb. per sq. in., which is the allowable working pressure for Class 50 lead pipe as desitrnated in Federal Specification WW-P-325.

Lead Pipe For Water Service Under Heavily Traveled Streets LTHOUGH its use is not man obstructions and formed into an in A datory, the installation of lead tegral expansion loop or gooseneck water service pipe is standard prawc ithout the use of fittings which are tice in New York City.

In addition to being durable and resistant to corrosion, lead pipe has other qualities which make it desir able for use under city streets. It has flexibility which makes it adapt able to installation in one piece with out extending the trench across the entire street. It can be bent around potential leak hazards. Lead is not responsive to vibration and therefore it is less likely to transmit sound than are other metals. Being a rela tively poor conductor of electricity lead is only slightly susceptible to electrolysis. The pictures show the installation LIA25911 From the main, under the street, offset down two feet and into the basement, this lead seriice pipe is in one piece. in progress of a 2-in. lead water ser vice without interruption of traffic, in this case the pipe was drawn through the space previously occu pied bv a smaller service pipe. In addition to the gooseneck which will be formed at the main end of this pipe it will offset down about 24 in. before it enters the basement. Both the durabilitv of lead itself and the absence of joints and fittings will contribute to the long life which can be expected from the service pipe. Manv cities throughout the l nited States require the use of lead service pipe with the result that botli propertv owners and water supply agen cies benefit from lead s convenience and durabilitv. New York's Third Avenue El. Bets A New Coat Of Red Lead E\^ Yorkers during the past ditional structures and stations in the N summer have perhaps been Bronx and Queens. The procedure startled on turning into Third Avinec ludes wire brushing and priming nue and beholding what seemed to with red lead paint of all of the iron be miles of brilliant red elevated and steel work including hand rails structure.

Maintenance work which had to be put off during the war has been resumed and under Columns newly coated with red lead, upper structure partis' unpainted, partly finish coated. taken in large units in an effort to reduce the large gaps in the schedule. The New 1 ork Cil \ Board of Transportation in common with othc administrative units of the citv gov eminent, including that responsible for the maintenance of the great bridges, makes the use of a red lead priming coat regular practice in maintenance painting procedure. That this practice is good is demon strated by the sound condition of the many steel structures maintained by the citv on which red lead has been used constantly. The work undertaken this sum mer was extensive. It included the 3rd Ave. structure from 44th to 105th Streets, the South Ferrv Sta tion, 9th St.. 125th St. and 129th St. stations in Manhattan as well as ad securing ties and other wood struc tures. This is followed after a suit able drying period by a coat of light grev-green white lead-base paint.
