Solid-state
h.v. module
for c.r.t. supplies
New from Brandenburg Ltd, the Model 695 is reported to be a compact, rugged high voltage module designed for providing the power supply for cathode-ray tubes and similar applications. The unit can be used as a direct replacement for Brandenburg’s earlier Models 576 and 778, using identical mounting centres. The Model 695 uses solid-state circuitry throughout; the output voltage may be varied over a wide range by simple adjustment of the dc supply. The power supply is vacuum encapsulated in a metal case, which prevents voltage breakdown and provides electrostatic screening. The main high-voltage output provides 2 kV to 15 kV dc at 200 pA (positive or negative to order) with a maximum ripple of 15 V peak-to-peak and a typical source impedance of 7 MQ. An additional low-voltage output of 500 V ac peak-to-peak (providing 500 PA after rectification) with a source impedance of about 100 kR is suitable for applications such as focus supply. The input may be varied according to the output requirements, up to a maximum of 22 V dc for 15 kV output. Maximum input current is 300 mA.

William McGeoch 8 Co (Birmingham) Ltd have been appointed by Corning Glass International as sole distributor to handle Corning’s machinable glass-ceramic material in the United Kingdom. The material has typical crystalline ceramic properties. Unlike conventional ceramics, however, it can be machined with ordinary metal-cutting tools. A research achievement in Corning’s laboratories in 1970, the unique material has come to market in only the past year.

British manufacturers will be provided with a unique opportunity to profit from the expanding Malaysian economy when the British Technology for Malaysia Exhibition is held in Kuala Lumpur from 5-l 2 April 1976. In a recent statement the Rt Hon Peter Shore, MP, Secretary of State for Trade said that ‘I am confident that the British Technology for Malaysia Exhibition has a valuable role to play in strengthening further the traditional trading links which exist between Malaysia and Britain’. Product categories cover a wide range and are capital goods orientated. The exhibition is already being widely supported by British industry, and many companies have already applied to take part. 446
