The new cartridge is available for am Models F3, F4 and F30. The aributors are Stenor, Ltd., Richmond, rrey, Improvements in their fuel filter have m made by the Zenith Carburetter Co., Ltd., Honeypot Lane, Stanmore, Middlesex. A new element has been introduced, and although the degree of filtration is now much higher than formerly, a full flow of fuel is maintained.

New vibration dampers are now in full production by Howard Clayton-Wright. Ltd., Wellesbourne, Warwickshire. Two types are available, known respectively as the double conical and the single conical.
In both cases a light, steel pressing is used to enclose one or two rubber elements (according to type), constrained by conical inner members. They can be obtained as fixed or adjustable units, the advantage of the latter being that the mounting can be " tuned " when in position.
The load range is 250-1,500 lb. Load deflection characteristics are similar whether it be a fixed or adjustable type of mounting.
The Ingersoll-Rand lmpactool 534, is now being made at the Manchester works of the company. It is capable of applying or removing nuts up to 1/-in.-bolt size. It operates on compressed air. The air motor runs at a speed of 700 r.p.m., the number of impacts transmitted to the socket being 1,270 per min. Its weight is 271 lb.
Impacting begins when the resistance to turning reaches a pre-determined value and continues until the throttle is closed or the torque required to turn the nut falls below this point. The motor drives the ball and cam-type impact unit through a single heavyduty planetary-gear reduction. The tool is made by Ingersoll-Rand Co., Ltd., 165 Queen Victoria Street, London, E.C.4.
