The expansion tank has sealed in it a chemical additive which ensures complete cleanliness of the cooling system and also seals automatically any leak that may occur. The additive automatically enters the cooling system the first • time any over-heating occurs. Prior to fitting the equipment the cooling system • should be drained and refilled with a 50/50 mixture of anti-freeze and water and no more topping-up is needed.
Uctrical Contacts
UBBER-MOUNTED electrical conk. tads are now available for all tractive tits fitted with Scammell M.H.-type itomatic coupling gear. The contacts are Added into heavy rubber mountings d provide for all electrical circuits.
Advantages claimed for the new-design ntacts are that no special washers or her forms of insulation are needed. icy are simple to fit, easy to maintain d are said to be virtually indestruc.1e.
.ernoulding Process
IIIFFICULTIES presented in retread' ing steel-cord tyres by their normal .:tthod have been overcome in a new ocess developed by Tyresoles, Ltd., ernbley, Middlesex.
In the usual process, the built-up tyre fitted into a rigid mould and -pressure ring curing applied by an air bag ed inside the casing. Because steelrd tyres are inextensible, they cannot retreaded in this way.
The new method employs a curing ig made up of several sectors. These ; fitted on to the built-up tyre by means a special assembly press, and the sing is cured in the normal way.

Iron-powder Electrode
A LOW-HYDROGEN, iron-powder r "I electrode which is claimed to enable mild steel to be welded at twice the speed possible with conventional electrodes has been introduced by Cooper and Turner, Ltd., Vulcan Road, Sheffield, 9. It is an addition to their Diadem range of arcwelding electrodes and is known as Topaz.
The new electrode is designed primarily for high speed down-hand welding in proCluction work where high quality welds are essential and where outlay on automatic welding equipment is not justified. Due to its low-hydrogen coating the electrode deposits metal free from cracktendencies and when welding low-alloy high-tensile steels, a much lower degree of pre-heat is necessary than with titaniabased electrodes.
