See "Thomas Register". Structural Steel Vibration Bases for Fans and Motors, Pumps, Compressors and Air Handling Units prevent motor misalignment, excessive belt wear and reinforce caat iron pump bases. Bolt hole locations are predetermined and fixed so that the vibration base becomes a template for lining, up the equipment Fig. 1. Type RB. Rubbtr-in~Shear Base. and securing it in place. Rubber-in-Shear is generally used where a static deflection of % in. maxi mum is adequate. Mountings are per manently fastened between structural channels and flat steel base plates, as shown in Figures 1 and 2. Spring Mountings with bonded acous tical pads are recommended for the more Fig. t. Type RB. Base End Section. Fig. 5 Type VMRH Rubber Hanger critical locations. Static deflections up to 1J in. provide isolation efficiencies ap proaching 100 per cent. Structural angles form a rigid floating platform for the equipment as shown in Fig. 4. The mounting used is shown in Figure 5. Individual Mountings are used under equipment that does not require a sup plementary base. Rubber - in - Shear mountings typically illustrated in Fig. 7 can be furnished for individual loads of 5 to 2,000 lbs. Spring mountings as illustrated in Figures 5 and 8 support loads ranging from 50 to 18,000 lbs. Spring mountings are manufactured with built in leveling and damping devices.

Open housings, not shown, or closed housings as shown in Figures 3 and 6 are made for attachment directly to the ceiling or insertion in the suspension rods. Standard hangers are made for loadings of 50 to 1,000 lbs. Spe cial units on request.

Publications Air Conditioning, Heating and Ventilating Engineering magazine for the men who design systems and specify equipment This monthly engineering magazine (established 1904) is read by the engi neers--by whomever employed--who design, specify, install, and maintain sys tems for heating, ventilating, air condi tioning, piping, plumbing, industrial refrigeration, process steam, and related services. These systems are installed in industrial plants, hospitals, office buildings, hotels, stores, schools, col leges, theaters., churches, institutions, government buildings, military installa tions, housing projects, etc. Readers include: Consulting engineers; engineers with architects, with large engineeringtype contractors, with utilities; engi neers with industrial plants and with large buildings; and others. To these men AIR CONDITIONING, HEATING AND VENTILATING brings, month after month, a steady stream of crisplywritten articles on the best current practice, boiled-down research results, mathematical short-cuts, handy tables, charts and Data Sheets. Subscription rates in U. S. and Canada; One year, IS; two years, tS; three years, S6. In all other countries, $7 per year. Heating & Plumbing Equipment News The "new equipment" magazine serving Contractors and Wholesalers This monthly "new equipment" maga zine, published in tabloid format, reaches by controlled circulation 35,000 contractors, wholesalers and other groups concerned with the sale and in stallation of beating and plumbing equipment. Only publication that reaches all these categories: Radiator and warm-air heating contractors, oilburner dealers, gas-burner dealers, plumbing contractors, and the whole salers and distributors who supply all the foregoing. Editorial content con sists of concise, illustrated articles de scribing new and improved equipment, materials, and tools placed on the market, also new catalogs and bulletins issued by manufacturers. Inquiries total over 100,000 per year for informa tion about specific products such as: Boilers, furnaces, gas-burners, oilburners, toilets, sinks, pipe, fittings, valves, pumps, pipe-cutting and thread ing tools, hot water heaters, room coolers, water softeners, dishwashers, controls, insulation, and many others!
