Patent GB-2171973-A (GB)
Title: In-line Capstan Winch
Inventor: FITZGERALD-SMITH LT COL JAMES
IPC: B66D1/74
Filed: 1985-03-05
Abstract: An In-Line Capstan Winch, which uses webbing instead of rope has the webbing reeved around a labyrinth of bars, until the desired tail-load is achieved, instead of being wound round and round a single bar. ALL the bars are rotated simultaneously through the same angle so that the static tail load due to friction is undisturbed. An unlimited length of webbing can be pulled in while the mechanical advantage remains constant; unlike a drum ratchet winch where succeeding layers of webbing increase the effective diameter of the drum. Better mechanical advantages are claimed for webbing than for rope of the same strength because it uses smaller diameter bars and has a smaller effective radius. The rotational method of providing the input torque makes it easier to motorise the winch, than is possible with existing in-line winches. <IMAGE>

Title: Reactive power compensating circuit
Inventor: LEWIS ERIC ANTHONY
IPC: H02J3/18
Filed: 1985-08-12
Abstract: A reactive power compensating circuit is particularly for use with mine winders and similar heavy industrial motor loads (1). The reactive power generated by such loads commonly varies widely in operation and consequently makes compensation difficult. The invention provides a capacitor bank (11) of basically fixed value in parallel with a variable inductive load, provided by a fixed reactor (15) supplied by phase controlled thyristor convertors (17). The net compensating load can then be adjusted to match the motor load reactive power sensed by transformers (35) and compared with a manually set reference (41) or with a reference derived from the current in the capacitor bank (11). <IMAGE>

Filed: 1986-09-10
Abstract: A protective device 30 for an integrated circuit 32 comprises respective Schottky barrier diodes 10a to 10d connecting the integrated circuit bond pads 42 and 44 to each of its power rails 34 and 36. The diodes 10 are arranged to be reverse biased in normal operation. They have a total junction area of 3 x 10 <6>cm<2> together with an active semiconductor region doping level of 3 x 10<16>cm<-3>. A low impedance capacitor 38 is connected across the power rails 34 and 36. An overload voltage appearing at either bond pad 42 or 44 forward biases one or other of the diodes 10a to 10d. This creates a low impedance circuit via capacitor 38 capable of sinking large currents and limiting the overload voltage to below a damaging level. The diodes 10 have higher current capacity and voltage tolerance than comparable prior art diodes, and are characterised by lower forward and high reverse impedance combined with fast switching speed. <IMAGE>
