mong the requirements in the new tyre gulations which came into force on Monday this week is one concerning the minimum nount of tread-1mm—which tyres must rye. In the past few months several depthcording gauges of the vernier-type have rived in my office, and some of these have ready been described in our ''New equipent" page.
Recently a dial depth gauge was sent to us r appraisal from Autocar Marine and Diesel ). Ltd., of Stonhouse Street, London, SW4, hich we have used quite extensively. This strument has a •2in. diameter dial-face calk ated in 0.5mm from 0 to 20mm. The depth tread is measured through a screwdriveroe pin and as the calibration shows 1mm 0.25in. on the dial, extremely accurate adings can be achieved.
The depth-sounding pin is placed into the ?ad groove and the instrument pressed down til the locating shoulders touch the surface the tread. As the gauge is removed from the -e a ratchet holds the pointer on the dial at a minimum recorded depth and this allows sy reading of the results. A press button in a -Centre of the back of the gauge casing eases the pointer ready for the next check. During three days of continuous treadpth recording recently. the Automark, as is called, proved that it was possible to eck 12 tyres in three different places on ch tyre in a total time of about 5 min.

Scandinavian design
The Avery Division of Lockheed Precision Products has introduced a low-cost, lightweight blow-gun of Swedish design. It is made from virtually indestructible Delrin and weighs only 3.5oz.

Degreasing system
Rapid and complete removal of encrusted dirt and grease from all types of vehicles, plant, floors and buildings using nothing but cold water is the role of a portable high pressure cleaning and degreasing system introduced by A. G. Wild and Co. Ltd., of Charlotte Road, Sheffield. This works by forcing the water at predetermined and constant pressures up to 1,000lb per sq.in. through an electric or petrol-driven hydraulic pumping unit, the heart of which is a motor-driven reciprocating lever which alternately actuates one of two hydraulic oil circuits. Each of these hydraulic circuits affects a diaphragm to cause a continuous suction to move the liquid through the pump system hoses for use in an uninterrupted flow.
Apart from the motor, the piston and reciprocating lever are the only moving parts in the pump, thus maintenance and overhaul are minimized. Periodic checks for hose connection leakage, motor operating and lever lubrication are normally sufficient to ensure efficient and continued pump service.
The equipment is available with either a 3 hp single or 5.5 hp three-phase electric motor or a 5.5 hp petrol engine. It is supplied complete with lance, 50ft of high pressure hose, suction hose and filter.
The system is wheelmounted or supplied with tanks and bolted into a van for a complete cleaning service for large industrial areas, building sites, airport runways and farms. Price: Standard wheel-mounted model from £248.
Air drill
A tin. air drill has been introduced by the Consolidated Pneumatic Tool Co. Ltd. as an addition to its range of automotive tools. This new model, the 7305, had a high power/ weight ratio and ergonomics have been applied to its design to give ease of handling for drilling in the kin. to iin. hole-size range.
Developing 0.5 hp the drill weighs 3Ib and is powered by a four-blade vane motor driving a reduction gear to give a spindle speed of 2,200 rpm. Metric ball and roller bearings are employed.
Control is by a ball-type throttle valve which allows the tool to be started at slow speed for centring before running at full power. The design of the trigger eliminates the possibility of a finger being nipped during closure. Exhaust air is vented through the nose of the tool which enables the work piece to be kept clear of cuttings and which cools the motor and gearbox. A silencer is fitted to keep the noise level at a minimum.
Made by: Consolidated Pneumatic Tool Co. Ltd., CP House, 97/107 Uxbridge Road, London, W5.
