MANAGEMENT BM-18 BETTER Westinghouse Electric’s Compressor Here is a general view of the new hermetically-sealed, V-type, 16-cylinder, 100-ton Westinghouse air-conditioning compressor. Engineering features also include no shaftseal, a refrigerant-cooled motor, and reversible oil pump. Starting is by line starter on reduced voltage, with capacitors being added for high power applications. Equipment News Westinghouse Oilers New Senled Compressor East Pittsburgh, Pennsylvania — Particularly suited for theatres, stores, factories and other air-conditioning applications requiring high capacity, a new ultra-compact 100-ton, hermetically sealed compressor is announced by the air-conditioning department of the Westinghouse Electric and Manufacturing Company at East Springfield, Massachusetts. For equal capacity, the new 16-cylinder, V-type, 1,150-rpm. unit is smaller, lighter, and more efficient than previous commercial compressors. Installation of the new compressor is simplified by a refrigerant-cooled motor which require no external ventilation. Small for its capacity, the unit fits in corners or odd spaces ordinarily too small. The reduced weight makes the compressor easier to handle and avoids the necessity of providing special foundations. Maintenance expense is reduced by the hermetically sealed design that has no shaft-seal to leak. The motor is completely enclosed with the compressor, eliminating the troublesome shaft-seal or ordinary units and preventing dust, dirt, and moisture from reaching working parts and lowering the efficiency and increasing the wear. The direct drive motor and compressor are mounted on a common in c o n st r u c t i o n, c o m f o r t and economical maintenance Here is the reason William I.

Eastern Sales Offices: 1501 Broadway N. Y. crankshaft, avoiding “lining up” problems, power losses incident to belt-drive and any need for lubricating the driving motor. A further safeguard to low maintenance is the use of a reversible oil pump which provides positive lubrication regardless of the direction of rotation. Servicing is a simple operation, since the entire operating mechanism can be exposed by removing the side plates from the crankcase. No pipes need be disconnected nor is the unit disturbed in any way. The 100-ton compressor is available for use on two or three-phase, 60-cycle circuits for 208, 220, or 440 volts. Standard magnetic “across the line” starters, or step-type starters, may be used, depending on the starting current limitations. The new 100-ton compressor weighs 4,200 pounds, and overall dimensions are 90 inches long, 34 inches wide, by 36 inches high. Normal rating is 1,212,000 Btu an hour, based on 37 pounds to the square inch of gauge suction pressure, 65 degrees Fahrenheit suction gas, 75 degrees Fahrenheit water in 95 degrees Fahrenheit out. New RCA Conversion Kit Camden, New Jersey — The Photophone Division of the RCA Manufacturing Company has introduced a new conversion kit, which will substantially increase the volume output level of certain types of sound-film reproducing equipments. It will also effect a saving of over 70 percent in photo-tube replacement cost, according to Edward C. Cahill, RCA Photophone division manager. The conversion kit consists of three photo-tubes (one for each projector, and a spare), a pair of metal brackets with the new tube sockets, and a lens. The kit, that is applicable to the Western Electric, Universal base, and 206 and 208 soundheads, permits the use of the RCA 868 photo-tube in place of the more expensive 3A and similar types of phototubes. "Invisible Sound Transmitter” Hollywood — One of the most perplexing problems arising from sound in pictures has been solved by Warners through the development of an “invisible sound transmitter,” which enables a player to hear music, cues, and instructions which must not figure in the final sound track. Radio transmission is the basis of the new device, invented by the Warner sound department, under the guidance of Major Nathan Levinson. Sound of any sort, it was stated, is sent into an offstage microphone and is conveyed to the player working before the cameras through a tiny bone conductor, affixed to his spine under his clothing. The conductor, in turn, transmit the impulses to the brain. The entire device, consisting of a conductor and receiver, is not much larger than a man’s fist. The invention permits the transmission of inspirational music to the player, and the director can give detailed instructions without his voice being recorded, and better timing in telephone and dictation conversations can be accomplished. Lack Gets Mohawk Line New York City — Harry Lack, president of the Lack Carpet Company here, announced recently that, as of December 1, his company will become distributors for the Mohawk Carpet Mills, Inc. Lack Carpet Company has been one of the leading distributors of soft floor coverings in the metropolitan area for years.
