approximate weight of the unit is 63 cwts. The makers are Chatwood-Milner Ltd., 44 Chancery Lane, London, W.C.2.

DRAWING STAND

The Mensa free-standing floor stand suits every possible drawing angle. Fitted with automatic locking, it may be positioned close to a back reference table to form a compact working unit.

The stand will take any size of drawing board and various drafting machines. It provides three separate ranges of adjustment - height, sliding movement, angular so that the draughtsman can select any working position for his board. All movement controls are within reach of the draughtsman from a sitting position.

Foot pressure on a bar at the base of the unit releases the locking mec- hanism and allows the complete board assembly to be raised or lowered through 18 in. This is achieved through an enclosed balance spring mechanism which is adjusted to the individual

weight of the drawing board and as- sembly. Locking is automatic when pressure is withdrawn from the foot pedal.

A hand lever on the right hand side of the stand gives angular adjustment through 90 degrees.

The makers are E.N. Mason and Sons, Ltd., Colchester, Essex, UK. Agents are Tan Kwang Seng and Co., Singapore.

TRANSCEIVER UNIT

Vacuum tubes and their attendant problems are eliminated with the phase modulation Series MF 960 transceiver which uses VHF output transistors. The unit can be supplied directly from a 13.5V or 27V battery, regardless of ground polarity and without converter.

Power consumption is thus reduced to a minimum, while low dissipation permits a very light, compact design.

MF960 transceiver unit

The transceiver will operate in var- ious frequency bands and standard channel spacings of 50, 25 or 20 kc. Receiver selectivity is obtained by means of a crystal filter.

Suitable for both mobile and base station applications, the MF960 unit is provided with selective call devices, employing various audio-frequency combinations.

The makers are Compagnie Gen- erale de Telegraphie Sans Fil, 41 rue Sartoris, 92-La Garenne, Colombes, France.

ROD BENDER

Patents have been taken out by a French company, Societe Mavilor, Boite Postale No. 13, 42-L'Horme, for a machine called the Stef 14 which automatically shapes steel reinforce-

ment.

The machine straightens reeled wire, directly measures it and shapes the reinforcement, afterwards ejecting it automatically on to a bar where it is stored. All grades of finned or improved adhesion steel can be handled.

The Stef 14 can work with either

single or double wire and has a traver- sing speed of about 1.2 m/sec. The parts obtained may have up to six sides with a maximum length of 1 metre,

plus a hook, with six folding angles from 0 to 180 degrees. Lengths and angles can be quickly set by means of two tabulators.

The capacity of the machine is limited to shaping smooth rods with a diameter of 14 mm (single wire) and 10 mm (double wire). Rate of output when forming a frame from a 10 mm. diameter wire with a developed length of 1 metre is 700 parts per hour with a double wire feed and 350 parts per hour with a single wire feed.

TILE ADHESIVE

Tiles may be fixed dry with Tilon tile adhesive which adheres to most surfaces, even damp ones, and is un- affected by extremes of temperature or by atmospheric conditions.

It will withstand continuous tem- peratures of 100°C. or extremely low temperatures without any loss of ad- hesion and is particularly suitable where hygiene and sterility are impor- tant as it contains no nutrients to har- bour bacteria, moulds or fungi.

Tilon is completely non-flammable and does not give off any toxic or vapours. It covers 7 to 10 sq. yd. per gallon depending upon the kind of sur- face to be tiled.

Polybond Ltd., Warsash Road, War- sash, Southampton, UK, are the makers.

ELECTRICAL WIRING

A prefabricated wiring system which makes it easy to install electrical wiring in rooms after a building is completed has been developed by Eldon AB, of Nassjo, South Sweden.

The system, called Form El, con- sists of an aluminium strip containing the electric wiring insulated in plastic, which can be put up around doors and ceilings instead of ordinary mouldings. Wall sockets, switches and lamp outlets are attached to the strip.

The Form El strip measures 58 x 16 mm (2.2 x 0.6 in.) and can be delivered in any length.
