Patent GB-2189038-A (GB)
Title: Optical switching
Inventor: ANDREASSEN JON
IPC: G02F1/29
Filed: 1986-04-10
Abstract: A portion of an input optical signal (S) is deflected to a respective output channel (4) by a holographic grating written in a photorefractive material by means of a write control beam (W) and an address optical signal output from means (fibre 5) associated with the output channel (4). The grating is erased using the writing beam (W) alone. Similarly an address signal from fibre 5' and the write beam W produces a respective holographic grating which causes a part of the input signal (S) to be deflected to fibre 4'. Thus there is provided an optical switch in which the output channel is "self-addressing". <IMAGE>

Title: Hydraulic brake system for use with an automotive vehicle
Inventor: BURGDORF JOCHEN
IPC: B60T8/1761
Filed: 1988-02-16
Abstract: For brake skid control of the wheel brakes of a dual-circuit brake system for use with an automotive vehicle, shut-off valves (13, 14) are positioned in the brake pipes (4, 7) leading from a tandem master brake cylinder (1) to the wheel brakes (5, 6; 8, 9) which shut-off valves are able to separate the tandem master brake cylinder (1) from the wheel brakes (5, 6; 8, 9). For ensuring the supply of pressure fluid to the wheel brakes (5; 6; 8, 9) during the brake skid control, a dual pump (21, 22) is provided with two separate pump circuits (28, 30) the initial pressure of which, with the aid of pressure control valves (17, 18) is limited to a maximum value corresponding to the pressure in the tandem master brake cylinder (1). The two pump circuits (28, 30) area respectively connected to brake pipes (4, 7) and, through regulating valves (32, 33) controllable by the brake skid control means, may be connected to the intake lines (24, 25) of the dual pump (21, 22).

Title: Crop harvesting apparatus and methods
Inventor: KLINNER WILFRED ERWIN
IPC: A01D41/06
Filed: 1989-01-17
Abstract: Apparatus for harvesting crop comprises a rotor 11 mounted on a mobile frame 12 and carries a succession of transverse combs 14 each formed of an array of outwardly projecting teeth 15 transverse to the direction of movement of the apparatus through the crop. Each tooth 15 is pointed with side edges diverging away from the distal tip of the tooth. The rotor rotates in the overshot mode and the combs intrude into the crop and gather crop stems between adjacent pairs of teeth and detach grain and grain heads, or other required crop parts, by rubbing or breaking the parts free from the stems. The junction of adjacent teeth 15 preferably has an enlarged aperture 21 to assist stripping and to allow withdrawal of stripped stems. In other arrangements the teeth may be replaced by a brush-like structure or by rods or other crop engaging elements, backed by plain transverse ribs for collecting and conveying detached crop parts. <IMAGE>

Title: Cable control mechanism
Inventor: KENNEY ANDREW CHARLES
IPC: F16C1/22
Filed: 1989-02-07
Abstract: A flexible remote control mechanism comprising a flexible force-transmitting inner member (1) which is axially displaceable relative to an outer guiding conduit (3) comprises an adjustment means (5) which engages a thread (3a) on the conduit so as to be displaceable therealong by screw action but wherein the elements (9) which co-operate with the thread are retained in operative position by a spring (10). When the adjustment means (5) is subjected to axial forces above a certain value the elements (9) becomes forced out of engagement with the thread to allow displacement of the adjustment means along the conduit. The adjustment means can therefore operate in either of two modes: a rotational mode for fine adjustment and a non-rotational mode for self-setting adjustment under excess load. <IMAGE>
