Century Electric Company, St. Louis, Mo., has published Bulletin No. 36, cov- ering the Century line of a.c. and d.c. fans. The bulletin contains complete descriptions of the company’s line of fans together with assembly diagrams of ceiling fans. Automatic Electric Heater Company, Warren, Pa., is now manufacturing the Clark Selective Load Control, which is designed to provide a more even load factor for domestic installations where electric range and water heater are in use. The device is so designed that when the electric range is in use, the electric water heater is automatically cut off the line, staying off until such a time as the demand from other devices is lowered to a predetermined point. The R. Thomas & Sons Company, East Liverpool, Ohio, has just issued an attractive folder on cemented type sus- pension units. The Providence Insulated Wire Com- pany, Providence, R. I., has taken over the insulated wire department of the Bourn Rubber Company of that city. Apparatus is being installed in the million-volt test laboratory of the Cali- fornia Institute of Technology at Pasa- dena, Calif. Four 250,000-volt trans- formers, with a capacity of 1,000 kw., have arrived and are being set up. The laboratory, the first of its kind in the West, was made possible through the cooperation of the college and the Southern California Edison Company. The power company erected the build- ing and the school is supplying the equipment. Dr. Robert A. Millikan will be in charge of the experimental work. The General Electric Company line of oil-filled instrument transformers is being redesigned to allow the use of the same type of coil and winding now used in the distribution type of transformer. The new design will also include the interchangeable bushing now used in General Electric oil switches, distribu- tion transformers and lightning ar- resters. Moe-Bridges Company, Milwaukee, Wis., has appointed the B & R Elec- trical Supply Company of Denver, Colo., distributors of the line in the Rocky Mountain region. The Electric Agencies Company, 56 Natoma Street, San Francisco, Calif., has moved to 655 Minna Street, that city, and will be located at the new address on and after May 1. B. A. Wagner, manager of the company, has just returned from an extensive trip to eastern factories. The O. C. White Company, Worcester, Mass., has recently published two “Ap- plied Illumination” folders that are de- signed to supplement the company’s latest catalog. One of these is entitled “The Trend of Industrial Lighting” and is devoted to shop fixtures and shows new styles of 23D and 24D drafting- board fixtures. The other folder, on “The Factors of Lighting Efficiency,” details the new 2LA conduit fixture and the new 3SA bench light. The folders can be obtained on application to the manufacturer. The Westinghouse Electric & Manu- facturing Company has recently issued a new 20-page publication, known as circular No. 1670 and entitled “Static Condensers for Power Factor Correc- tion.” In this circular the need for power factor correction and the meth- ods of obtaining high power factor are discussed. The method of selecting the proper corrective device for power fac- tor is carefully analyzed, and the fields of application of synchronic and static condensers set forth in diagrammatic form. A complete illustrated descrip- tion of Westinghouse Type LD static condensers with wiring diagrams for two and three-phase equipment is in- cluded in the circular. The method of calculating the corrective kva. neces- sary for an installation of condensers and a chart for determining the per cent of reactive kva. required to raise the power factor to a desired value are next presented. A tabulation of the weights, dimensions and losses of static condensers and the weights and dimen- sions of transformers conclude the in- formation given. The Lovell Manufacturing Company, Erie, Pa., has recently placed on the market a new portable electric clothes wringer designed for use with washing machines not provided with power wringers and as an auxiliary in laundry equipment for homes, hotels, clubs, schools, etc. As the wringer is mounted on a tripod, it has a swivel hanging per- mitting it to be swung to any position over a washer or stationary tub. For permanent use on stationary tubs or boilers, the wringer is built without the stand and provided with clamps to hold it in place. Power for turning the rolls of the wringer is supplied by a West- inghouse heavy duty electric motor built for operation on either direct or alternating current at 110 volts. Commercial Electric Company, San Francisco, has moved to 1925 Howard Street in that city. Henry D. Sears, general sales agent for Webber wiring devices with offices in Boston, Mass., has recently issued a wall poster devoted to illustrations and descriptions of Staylit. The device is a lamp socket designed to keep a lamp lighted for a minute or two after the cord controlling it has been pulled. Birkel & LeGassick, wholesale elec- tric supply company, is developing a large business at Santa Monica, Calif. The company is located at 702 Santa Monica Blvd. Harvey Hubbell, Inc., Bridgeport, Conn., has recently placed on the mar- ket a new toggle switch. The company has also announced a line of 10 and 20-amp. polarized shallow flush recep- tacles which have been re-designed to fit standard convenience outlet face plates. The receptacles are only 1-3/32 in. deep and are therefore suitable for thin partitions. Atlantic-Pacific Agencies Corporation, San Francisco, has established sales agencies in Chicago, Philadelphia, Pitts- burgh, Boston, New York City, St. Louis and Dallas, Texas. The American Airdry Corporation has recently moved its head offices and fac- tory from Groton, N. Y., to Chicago, 111. The company manufactures Airdry, ‘‘The Electric Towel,” and has moved to Chicago to secure a more centrally located distributing point. Pacific Coast representation for the company remains the same and is in charge of the Airdry Electric Service Company, with head- quarters in the Rialto Bldg., San Fran- cisco. The Electric Outlet Company, Inc., New York, N. Y., has brought oat a new product which will be called “wire- nuts.” The new device is made of brass and Bakelite and is for use in making wire joints in outlet boxes and else- where. Curtis Lighting, Inc., has moved its Los Angeles office from the Pacific Finance Building to 1040 Merchants National Bank Building in the same city. The company has recently opened a lighting studio at the new address. The F. W. Wakefield Brass Company, Vermillion, Ohio, Ivanhoe Works of The Miller Company, Cleveland, and the Na- tional Lamp Works of the General Electric Company, are issuing a new booklet entitled “A Central Station Campaign that Sold 2,609 Store Light- ing Units in 10 Days.” The book tells of the experience of the Ohio Public Service Company in making 2,609 sales to 6,370 stores in seven medium-sized cities, and is designed to show other central stations and contractors how such a campaign should be conducted and as to the results that can be ob- tained. The information concerning the mapping out of such a better store lighting campaign is exceedingly well written and should be of value to any- one considering the possibilities of such a sales drive. Copies of the book may be obtained free of charge from any of the three manufacturers cooperating in its publication. Gearhart Hotel, Gearhart-by-the-Sea, Ore., where the annual convention of the Northwest Electric Light and Power Association will be held, June 25-27, 1924.
