Twin Tire. General Tire & Rubber Co.

will put on sale a standard-size tubeless tire with two sets of treads, separated by a center groove. Each tread has separate contact with the road, thus providing better traction and reducing wear.

Pint-Size Engine. American Motors has developed a 4-cylinder air-cooled engine weighing only 200 Ibs. v. Nash Rambler's 450-lb engine. Made largely of aluminum, the 62-h.p. motor occupies half the space of a conventional water-cooled auto engine. It will also be available next year in bigger units (6 and 8 cylinders) for use in autos, air-transported military vehicles, and stationary equipment, e.g., pumps, generators.

Right Time. Most 1957 auto models will have a new kind of clock, developed by General Time Corp., containing a device which automatically adjusts the clock to run on time. If the hands are set forward to correct a clock that has been running slow, the regulator makes the clock run at a faster rate. When hands are set back, the clock automatically adjusts to a slower rate.

TV Banking. At the Mechanics and Farmers Savings Bank, Bridgeport, Conn., Mosler Safe Co. has installed a closed television circuit and loudspeaker system connecting an indoor teller's cage with a curbside depositor's booth. Deposits and receipts are sped through a 100-ft. pneumatic tube. Mosler plans eventually to install remote-control bank booths at subway and rail stations, main intersections.
