Which of the following most accurately describes the problem?

FIVE mobile television control rooms are being built by Bonallack and Sons, Ltd., 40-42 Cannon Street, London, E.CA, to the specification of• Marconi's Wireless Telegraph Co., Ltd., and the first has now been completed. They had to be capable of operating over rough country and at high speed, in all weathers, night or day, and to withstand some degree of overloading.

The weight of the body was reduced by about 30 cwt. by constructing it, except the floor, in heat-treated threequarter hard aluminium alloy. The main structure of squeeze-riveted members is covered with an outer skin

of hollow-riveted aluminium alloy sheet, and the interior is panelled in hardboard. The strengthened roof is lined with sound-absorbing material and the whole body has a heatinsulatinsz lining of bonded fibre-glass between the inner and outer skins.

• Externally, the body has a pleasing appearance. The upper half is— cellulosed and below the waist it is finished in polished corrugated alluminium alloy, there being no vertical mouldings. The rear part of the body has seats and folding tables for the crew, and most of the television equipment is housed forwardof a bulkhead. A Temkon air-conditioning plant serves the whole of the production area. The 5 kW of heat produced in the servicing area is removed by four extractor fans in the roof, and by special air ducts in the floor. Special precautions have been

taken to prevent rain and snow entering when the van is not in use.

These new vehicles will be used by Associated Rediffusion, Ltd. This company is one of the programme contractors to the Independent Television Authority.
