23 August 1957 275 Hew instrument and electronic laboratory of Northwest Industries, Ltd., whose plant is located on Edmonton. us HR RISE The home of Sperry Gyroscope Company of Canada, on Cote de Liesse Road, Montreal. Diversity of production is here the keynote. continued to design and produce hydraulic controls and ground equipment for the R.C.A.F. and for Canadian civil operators. A new development is an additional 40,000 sq ft factory at Uxbridge, Ontario. Pye Canada, Ltd., 82 Northline Road, Toronto 16. ALL products of the Pye Group with market applicationsin the Dominion are currently merchandized by Pye Canada. The company comprises five divisions, concerned respectivelywith radio-communications; broadcasting, underwater and industrial television; telephone apparatus; scientific instruments;and domestic high-fidelity equipment and portable radios. Branch offices are located in Halifax, Montreal and Vancouver. Pyeairborne equipment is at present being used by Canadian Aero Service, Spartan Air Services and Renting Aviation. Servomechanisms (Canada), Ltd., Rexdale Boulevard and Kipling Avenue, Toronto IS. THIS company has recently attained a major positionin the field of aircraft instrumentation and automatic-control equipment. It has assumed the business in Canada formerlycarried on under the name of Industrial Electronics of Canada, Ltd., and has also become the exclusive channel for world-widedistribution of the products and services of Servomechanisms Inc. of New York and Los Angeles, of which the Canadianorganization is an integral part. The company is now located in new quarters near MaltonAirport. The plant is fully staffed and equipped to manufacture the complete Servomechanisms range of air-data and related com-puters and display equipment. It also distributes the lines of servo and hysteresis-synchronous motors, magnetic devices andvacuum-film products made by the components group of the U.S. company. The Canadian company's own engineering staffhandle requirements arising in world markets for both new equipment and for adaptations of the products of the Americanorganization. The Canadian company is currently operating at approximatelydouble the level of last year's activity, and present contracts call for a further doubling of business in 1958. Present productionincludes fire-control computers and control units for Canadian military aircraft for both domestic and export markets, as wellas specialized components and test equipment being shipped directly to overseas customers. The company is now activelyengaged in developing applications of its proven techniques for civil aircraft and in scientific fields associated with aircraft. The president of the company is C. H. Hartley. Simmonds Aerocessories of Canada, Ltd., 5800 Monkland Avenue, Montreal 28. THE Canadian licensee of Simmonds Aerocessories, Inc., ofthe U.S.A., this company has continued to work on the develop- ment and manufacture of a wide range of aircraft accessory equip-ment, including liquid gauging, latches, controls and special fasteners. The company also represents Hi-Shear, Saunders Valve,King Aircraft Corporation and other companies. Spartan Air Services, Ltd., 74 Sparks Street, Ottawa 4. ESTABLISHED only ten years ago, Spartan is today one ofthe fastest-growing companies in Canadian aviation, and operates the largest air-survey fleet—using 70 helicopters and fixed-wingaircraft. This year, Spartan has scheduled or in progress some 32 geophysical exploration surveys for governments, mining firmsand oil-exploration companies in Canada, Mexico, Columbia, India, Malaya, Indonesia and Kenya. The company has photo-graphed from the air some 1,500,000 square miles of northern Canada for the Canadian government for the production oftopographic maps, and is working on one of the largest electro- magnetic surveys yet undertaken anywhere. This covers 7,000square miles of uncharted land in the Canadian sub-Arctic, and is being carried out for over 30 Canadian and U.S. mining com-panies in a search for nickel/copper deposits. Spartan's aircraft fleet includes Lancasters, Mosquitos,Ansons, Cessna 310s, Cansos, DC-3s, and Bell, Sikorsky and Vertol helicopters. Nine Vertol H-21B helicopters were recentlytaken over from the R.C.A.F. and will be used on Mid-Canada radar line re-supply and transport duties. The company, whichpioneered high-level (30-35,000ft) commercial photography with fixed-wing aircraft, is the first commercial operator in the worldto use the H-21B helicopter. New data-gathering instruments and new techniques have beenemployed by Spartan in order to carry out reconnaissance and detailed natural-resources surveys faster and more cheaply than byconventional methods. Spartan has headquarters in Ottawa and branch offices inToronto, Montreal, Calgary, Edmonton and the U.K. The company also owns Aerophysics of Canada and Harward,Maclachlan and Company of Kenya, and has a minority interest in Transair, a Canadian airline, and Canadian Aero Service, Ltd. Sperry Gyroscope Co. of Canada, Ltd., P.O. Box 710, Montreal. REFLECTING a trend common to both the Canadian andBritish industries, Sperry's manufacturing operations have been slightly decelerated during the past year but are becomingincreasingly diverse in character. Typical of present contracts is that which requires an altimeter and an airspeed indicator (ofKollsman design) for two CS2Fs per month—a far cry from 1955 when Canadair alone were fitting the company's instrumentsto 25 T-33s and 30 F-86s per month. To offset such trends Sperry have developed a pressure transducer, originally designedfor use in an altimeter, into a form suitable for papermaking machinery; by the same token, aircraft servo-controls are beingused for the automatic control of machine-tools. It is also perti- nent to point out that, like all Canadian accessory companies,they have to compete directly with American firms for Canadian business, yet a 15-per-cent tariff effectively handicaps sales ofCanadian products in the U.S.A. Sperry's Canadian company is in production upon a widevariety of aircraft instrumentation, including the well-known Gyrosyn systems and such equipment as amplifiers, synchrosand servo motors. In addition, a considerable proportion of the manufacturing facilities is at present devoted to production ofA-4 gun/bomb/rocket sights for the 225 Sabre 6s for the Luft- waffe. The company are also, of course, concerned in the pro-vision of service-support for products of the U.S. parent com- pany in use in Canada, including Zero Readers, A-12 autopilots,engine analyzers and the new SP-30 flight system for the T.C.A DC-8s. Great emphasis is being placed on the company's DevelopmentEngineering Department, which has a technical strength of 100. A major accomplishment of D.E.D. is the LDG-1 low-driftgyro, which has a random drift under +1 deg/hr when operating as a free gyro. Owing to its great value in the Arctic (wheremagnetic references are unobtainable) the LDG-1 is already the subject of an initial order by the R.C.A.F. At present under-going final flight testing, a servo-diaphragm altimeter is claimed to provide more sensitive and accurate height information thanis currently available; other devices under development include an engine synchronizer for turbojet aircraft and a computerwhich corrects for gyro-compass gimbal errors resulting from roll and pitch.Floorspace in the company's modern factory on Cote de Liesse Road, Montreal, totals 90,000 sq ft and employment is approxi-mately 600; the managing director is B. W. King. Standard Aero Engine, Ltd., P.O. Box 764, Winnipeg. STEVENSON FIELD, Winnipeg's main airport, is thehome of Standard Aero Engine, who are responsible for the repair and overhaul of a range of some 20 types of piston engine.In addition the company acts as sales representative for several U.S. engine manufacturers, and a second main division of thecompany is devoted to aircraft and engine accessories. Over 400 different types of accessories are handled, including starters,generators, ignition coils, control boxes and hydraulic and pneu- matic equipment. Comprehensive test-rigs are utilized.
