Motor-operated Doors A T Stockholm's bus and Which Stop AutomaticI-1 trolleybus depot there is ally a number of tall and some
what heavy sliding doors. These are, however, rendered easy to operate by the use of electric motors. It is, of course, important that no person or object should be caught between the door and its jamb. To prevent this, a neat and effective switching arrangement is employed. Mounted on the end of each door is a vertical rubber tube with internal strip contacts at each side. The circuit is so arranged that any depression of the tube immediately cuts the current.
Imagination May Magnify COMPLAINTS have someShocks Received 1"--. times been made to bus in Alighting . . companies by passengers who have received electric shocks when alighting from vehicles. This, of course, is due to the static electricity collected by the bus on its run, discharging to earth when contact is made by the passenger's body and the ground. However, such shocks are usually only the merest pinpricks, but are probably magnified by the recipient's imagination. The greater shock that a passenger may suffer from is not the result of the high-voltage, but of seeing a spark occur between his foot and the ground. A Simple Method of I N the chassis-finishing shop Dissipating Engine of Albion Motors, Ltd., Fumes itrouble was experienced with the exhaust fumes from the oil engines, which tended to collect close to the floor.

Difficulties in TrekkA MIDLANDS family of n g to Southern J-1. trekkers, headed by Cap Rhodesia tam n P. C. Burgess, a former
R.A.S.C. officer, left England some two months ago intending to travel to Southern Rhodesia via the Sudan in a converted Guy ex-Army radar truck, but owing to a ban on such action by the Sudanese Government the route had to be changed and a crossing made of the Sahara. In a letter to Guy Motors, Ltd., from Kano, Northern Nigeria, Captain Burgess said that the last 2,000 miles was "simply hell" so far as roads were concerned. One evening the vehicle was stuck in the sand, and it took until the following morning to get
it out—a distance of only 15 yds.—which wasted seven gallons of petrol. The cost in fuel of making the 2,000 miles ran into £100. Where there are roads these are corrugated, and they give the vehicle a terrific hammering, although there has been no mechanical trouble. At the time of writing there were still 2,000 miles to cover to Salisbury British Legion Saves A FTER serving 16 years in Business for Ex-Serr-ithe Army, an ex-Service vieeman man bought for £200 a motor van for his _trade in fish and greengrocery, and was soon serving 200 customers a week. Then he was stopped by the police and warned that his vehicle was unroadworthy. The repairs took two months, and faced with loss of capita!, trade and customers, he decided to sell the van. The case having been brought to the notice of the British Legion, it has granted him a free-of-interest loan to pay the repair bill. The Legion would have been prepared to have helped earlier in this matter. This experience constitutes a warning that vehicles should not be purchased without advice from a reasonably expert source.
