Other new Davenset products are a pistol-grip cell tester for sealed-top batteries, an inverter for producing AC. at mains voltage from a 12-v. battery, and a power pack to provide smooth, direct current at 12v. from 240v: A The latest electronic equipment from V. L. Churchill and Co., Ltd., is a portable speedometer tester and engine tachometer, It consists of a wheel follower, which transmits electric pulses to an electronic circuit. and from there to a meter graduated in m.p.h. and engine r.p.m. The wheel follower is removed, and a connection made to either coil or distributor to check engine revolutions. The company are also showing an electronic wheel balancer.

Wheel-balancer

The Replex electronic wheel balancer made by the Australian company, Repco, Ltd., can be seen on the stand of Kerry's (Great Britain), Ltd. Readings are taken by jacking-up the vehicle and spinning the wheels with a motor unit at a speed equivalent to 50-100 m.p.h. A vibration pick-up head which, when placed under the axle or wishbone, picks up out-of-balance as small as 1/10 oz. A meter reads the amount of unbalance and a stroboscopic flash indicates where the weight or weights should be fitted. The wheels are statically and dynamically balanced on the vehicle, the average time for each wheel being five minutes. The price of the complete unit, including is range of weights, is £174. .

Another type of electronic wheel balancer, known as the Alemite, is shown by StewartWarner, Ltd. Two models are available, one being snitable for light vans, the other for commercial vehicles. They are portable units and can be used to detect kinetic and dynamic unbalance on a rotating wheel. The entire wheel assembly, tyre, rim, hub cap and brake drum, is balanced without removing thewheel or adding additional attachments.

The unit consists of an electrically driven wheel. spinner, which engages on the wheel by the simple operation of a hand lever. Reverse operation brings into use a brake plate. A pick-up arm is magnetically attached to the wheel brake plate, or suspension, and transmits out-of-balance vibrations through a meter unit in conjunction with a strobe light, which locates out-of-balance. The price of the standard model for vans is £156 10s., and the medium duly model for heaider vehicles is £190.

Alignment Quickly Checked

The Laycock Engineering Optiline gear enables• all aspects of wheel and steering alignment to be checked, corrected as necessary, and recheelted in the minimum of time. The unit consists of two projectors for wheel rim mounting, a screen assembly, and turntable for level rotation of the vehicle wheels. The degree of wheel misalignment is indicated optically on the screen.

Particularly useful for the garage where wheel alignment has to be carried out on an area that has not been specially prepared is the Churchill glass-fibre floor-level indicator. Basically, the equipment consists of two pads connected by an adjustable tubular bar containing a spirit level. By a miero-screw adjustment, the spirit level can be zeroed to give a reading of the slope in the floor at the point being measured. This measurement can he used to correct the angles shown on the steering gauge.
