Goodrich Canada Ltd., the event is also Canada's oldest auto race, running every year but one since h1959. Drivers from across Canada and the U.S. wihl be competing in a variey of Porsches, Corvettes, Camaros, Production sports cars and sports racing cars. The race was won ast year by former Canadian driving champion, Ludwig Heimrath and co-driver Fritz Hoch- reuter, making their Porsche 9115 ast the distance while faster cars succumbed to the rigors of six hard hours. B.F.G. sponsorship of the event is dcsigned to upgradc thc stature of the race over the ncxt couphe of years. A dmission for the entire Dominion to Independence Day Sprints weckcnd or any of the four days is $5.00. Mosport officiaIs say they expect a large crowd of campers to take Advantage of the bargain price and the opportunity to sec so many varied forms of racing. Camping, water and wood are free for the entire weekend. 'tii next wcck, Happy Motoring! Hydro Research Division Celebrates 6Oth Year Research at Ontario Hydro may lead to a major break- through in the cost of installing bigh-voltage transmission lines underground. A special group of engincers is developing a unique concept which involves the underground installation of a watertight pipe about eigbt feet in diameter. Threc aluminum tube conductors, one for each ehectrical phase, would be supported inside the duct by sohid insulating spacers. The ducted air medium underground transmission system is dubbed DAMUT. Preliminary estimnates indicate that DAMUT might cost Ithree times as much as an overhead line compared toI 5 to 1 for present day underground expenditures. Another underground system being investigated at Hydro involves the use of sulphur hexafluoride gas (SF6) as an insulating medium. The test is being conducted in co-operation with I-T-E- Circuit Breaker (Canada) Ltd., under contract to B.C. Hydro and involves operation of a short'lcngth of test equipment in the Toronto area prior to installation of such a systcm at a B.C. hydro-electric station. Hydro has also decided to use SF6 equipment in a new mini transformer station in downtown Toronto. It wil bouse compact SF6 insulated switchgear, thcreby reducing land requirements. The station will be fed by conventional' underground lunes. If these experimental projects pay off, Hyd ro wilh have made major inroads in its efforts to fînd an economic means of providing high-voltage underground transmission which now involves prohibitive costs. Research of this nature is only part of a varied array of about 2,000 on-going projects by a staff of 375 at the Ontario Hydro W.P. Dobson Laboratories on Kipling'Ave. in Etobicoke. Biological studies on the effects of warm water discharge from t heria l-electric stat ions, research into the remnoval of suiphur dioxide'from the stacks of coal-fired generating stations and developmnental work on inuproved overhead transmission lines are higli priority items as the Hydro researchers grapple with new criteria set ini part by a more demanding public. -These thiîigs would have coîne ,aniyway," says director J.1H. Waghorne, "but pulblie pressure is hastening the pro- cess. Rather than duplicate work being done ly other research organizations, the division's objectives cati for the selection of areas of R and D) fot being adequately pursued elsewhere in the world. At the saine time. employees keep abreast of the international sceîue by serving on varjous tectînical commnit tees. Hydro is also wvorking with universities, consultants and (tler scientific organizations ini R and D projects. Research is tuot new 'to the Ontario utility. ln fact, this mlontlî the research division celebrated its 6Oth anniversary. Many developmnents at 1-ydro have been copied aroind the world. These include torsionail&dimpers to reduce transmission line vibration, infrared surveillance of conductor joints, the soniscope, a device whose sound waves can penetrate 60 feet of concrete ini a dam for the detection of faults, fault-Iocating schemes for overhead lines, special methods of spray îng rights - of - way from the air to reduce mainten- ance costs, and many more. One of the early tasks undertaken by the research laboratory concerned the safety testing and approval of electrical appliances in Canada. This began with a staff of four hydro employees and grew to more than 100. In 1940 Hydro's seal of approval had become a recog- nized label across the country and it was decided that from then on the labelling shouhd be done by the Canadian Standards Association. For the next ten years research in this field was contracted to Hydro by the CSA which eventually took it over. HOSTELS BROCHURE PUBLISHED For the benefit of young travelers this summer, thec federal government bas issu- ed a fold-out brochure list- ing locations and services of government-supported youth hostels across the country. The brochure was publish- ed by the Dcpartment of the Secretary of State which administers several summer youth programs, including t- he $1 .5 million hostels pro- gram. Listed in the pocket sized brochure are 119 hostels, in- cluding 28 in Ontario. Hos- tels provide a comfortable night's lodging for young bit- chikers for 50 cents. Brochure copies, free of charge, can be obtained from hostels themselves, from In- formation Canada bookstores or fromn Summer '73 Com- munications, the information arm of federal summer youth programs. The Toronto ad- dress of Summer '73 Com- munications is 6th Floor, 241 Jarvis Street, telephone 369- 3071.
