Analysers and Chargers from Laycock THE extensive range of workshop equipment made by Laycock Engineering Ltd. has been extended by the introduction of two new engine condition analysers and two fast battery chargers. This is a new field for Laycock and examples arc being shown at the Motor Show by the concern.
Both the analysers can he used to check completely engine electrical circuits and engine condition of four-, sixand eightcylinder engines with 6or 12-V. systems. The main difference between the two is that the Autoscope has a 4-in, oscilloscope which shows only a secondary pattern whilst the Autoscope Major has an 8.5-in, oscilloscope showing primary and secondary patterns to give a greater refinement to the tests that can be carried out. The machines are of a 'similar size and layout and all instruments and controls are located in an upper console. A lower cabinet which supports this has a tray for storing leads and so on and a compartment intended to house an Autogas Analyser (an optional item to give information on exhaust gases) and other complementary equipment available.
There are two versions also of the Laycock fast battery charger, one can deal with 6and 12-V. batteries whilst the second deals also with 24-V. units. Both are given the name Auto-Specdcharger and operate off 200to 250-V. ac. mains supplies. The usual facilities of this type of equipment are provided, engine starting, fast charging, and battery boosting. In addition, the charger can be used as a slow charger for a number of batteries.
Makers: Laycock Engineering Ltd., Garage Equipment Division. Victoria Works, Millhouses, Sheffield. 8.
Price: Autoscope £250, Autoscope Major £350, Auto-Speedchargers £69 5s. and £95 10s. respectively for the small and large units.
Extricator Device I-1 A SIMPLE device to improve the rear wheel traction of
vehicles on soft ground and snowor ice-covered roads has been developed by Dennis Bros. Lid. It is called the Denris Extricator and when used performs the same function as a differential lock.
The Extricator consists of two rollers fitted to the end of a solid shaft mounted on pivots just beh:nd the rear axle. Two hand screws are used to bring the rollers into contact with the rear tyres—one on each side of the vehicle.
Makers: Dennis Bros. Ltd., Guildford, Surrrey.
AN all-glass sealed-beam headlamp unit has been introduced by Philips Electrical Ltd. This is the first time the concern has entered this particular section of the U.K. market and the unit—Type 7002—is being exhibited at the Motor Show.
The Type 7002 is rated at 60/45 W (12 V) with a left-hand dip and has a diameter of 7 inches. This means it can be used to replace units fitted in most British vehicles, either of the same type or those with a separate bulb although in the latter case an adaptor is required to replace the existing bulb holder.
A block-pattern lens is used, this being designed by Philips to reduce the amount of stray light. The beam given by the lamp is generally flat and rectangular. There is a relatively sharp horizontal cut off at the top of the beam which is a particular advantage in preventing glare to oncoming traffic when driving on the dipped beam. In this respect, the new unit gets close to Continental' standards.
Makers: Philips Electrical Ltd., Century House, Shaftesbury Avenue, London, W.C.2. (The light unit is produced in Holland.) Price: £1 9s. 6d.; adaptor to convert light units with separate bulbs, 3s. 3d.
