A trailer park-brake control developed by Neate Brake Controls combines a straight rack with a repeat stroke action which gives an automatic increase in leverage at the end of each stroke. It will pick up approximately 3in. of cable per stroke. The control costs approximately 25 per cent less than the comparable rotary action system.

Information display
Ewell Court Electrical Ltd has produced a communication system designed to display and signal information. The system consists of a master unit, located at the operation end that is linked via a cable to a slave unit at a central control or supervisory point; in a large organization it could be situated some distance away.
A group of 30 bright display lamps on the master unit have individual switches, each lamp being numbered with a blank space for legends. Operation of any lamp switch on the unit is shown on both master and slave units.
In a typical application a machine operator would indicate completion of a particular job, that further work was required or a break-down of his machine by pressing the appropriate switch. Uses could include indication of vehicle availability in a transport pool, stock shortages in warehouses or supermarkets and staff in /out movements. Both master and slave units are housed in steel wall-mounting cabinets finished in steel and hammertone charcoal grey with blue and black lettering.
Dimensions of the master unit include a width of 2O-in., a height of 11 in. and a depth of 54in; the slave unit has a width of 16iin., a height of llin. and a depth of 31-in. Snap-in lenses in five coding colours can be replaced from the front; a lamp failure extinguishes the corresponding lamp in the other unit. There is no limit to the number of units that may be installed.
The master unit can be used on its own, or with one, two or three slave units.

It is designed for use with standard industrial electric or air-operated drills with a minimum chuck size of fin. and best results are achieved when operated at a chuck speed of around 900 rpm. The maker recommends that the cutters are used with a coolant. Resharpening is done in the same way as that applied to a twist drill.
Model 410 has a range of dia, while the range of model 411 is „rin./in. die.

Cab lining
A range of self-adhesive fabric and plastic materials have been introduced by the Marine Products Division of Arno Adhesive Tapes.
The self-adhesive materials are clean and simple to work with — the material can be offered-up into place a number of times to ensure a perfect fit prior to the removal of the protective backing paper for final positioning.
The materials also provide an element of sound-proofing and minimize condensation problems. One of the materials sandwiches a close-cell foam between decorative trim and the adhesive for additional soundproofing and condensation prevention.
Elimination of impact adhesives also minimizes fire hazards Operators can work continuously without pausing to allow the fumes to clear.
Material widths are up to 24in. and roll lengths of up to 30yds. are available. Price from 98p. per yard.
