Title: Radar antenna system
Inventor: STEVENS MICHAEL CHARLES
IPC: H01Q25/02
Filed: 1988-04-29
Abstract: A radar antenna system comprises a circular array of column radiators (11) and monopulse means (14, 16, 21, 22, 23) for transmitting and receiving signals on cyclically selected sets of the radiators, each set having a plurality of selectable different look directions. The azimuth of a target is given by the algebraic sum of the particular look direction of the radiator set receiving the reply and the deviation from that look direction determined by the monopulse means. With monopulse, azimuth determinations become more inaccurate the larger the deviation from the look direction. To enhance the accuracy and the resolution obtainable from discrete look direction, the system further comprises means (30) for averaging a plurality of azimuth determinations of the same target made in different look directions. The azimuths in the average are weighted with increasing importance being attributed to determinations the smaller their deviation from the particular look direction of the radiator set which received the reply. <IMAGE>

Title: Inflatable crash bags
Inventor: HALAND LARS YNGVE
IPC: B60R21/268
Filed: 1988-07-15
Abstract: A safety device in a motor vehicle comprises an air-bag 3 and means to inflate the air-bag in response to a side impact on the vehicle. The air-bag 3 is positioned (eg inside a door) so as to be located, when inflated, between a person sitting on a seat 1 in the vehicle and the side of the vehicle. Initiation of inflation of the air-bag may be caused by deformation of the outer skin at the side of the vehicle breaking a frangible material, actuating a valve acting on a reservoir of hydraulic fluid or completing an electric circuit to release gas to fill the air-bag. <IMAGE>

Title: Electric power assisted steering for vehicles
Inventor: MCMAHON PAUL
IPC: B62D6/00
Filed: 1989-04-28
Abstract: A power assisted steering system for vehicles using electrical rather than hydraulic power, which maintains the "feel" of a non-assisted steering system and is adjustable for degree of assistance.

Title: Multi-algorithm lift control system
Inventor: GODWIN ADRIAN MICHAEL
IPC: B66B1/46
Filed: 1990-11-27
Abstract: A lift control system is adapted to operate selectively according to any one of several call processing algorithms in order to provide both direction collective two button control (up/down) and destination hall call control in which the destination is designated before the arrival of the lift. Manual control means capable of being modified to operate according to the selected algorithm may include a touch screen display (TD) with a software driven interface providing corresponding alternative video displays that indicate touch responsive areas of the screen that are appropriate to the algorithm in use. Therefore the control computer (CC) can be set to operate according to either algorithm, either manually, or automatically, in response to traffic demand. <IMAGE>

Title: Vehicle direction indicator lamp control system
Inventor: SURENDAR PATHI THIRUMALA
IPC: B62J6/00
Filed: 1990-12-05
Abstract: Automatic cancelling of a turn signal is effected by an arm 10 coupled to the steering mechanism of a four wheeled vehicle, (Figs 6, 7) or a two wheeled vehicle, (Figs 8, 9). Operation of a push button switch (31), (Fig 2), for a left turn signal energises a rotary solenoid 19 to ratchet a cam disc 23 from an unswitched to a switched position closing a microswitch 26 to energise left turn lamps (36), the solenoid 19 also rotating a lever 27 acting via linkage 51, 15 to turn the cam disc 23 of right signal solenoid 38 back to an unswitched position, if in a switched position, whereby right lamp microswitch 29 opens. As the steering assembly moves for a left turn, projection 12 on arm 10 moves in direction 48 and rides over a lobe 24 on cam disc 23 of solenoid 19. As a turn is completed, projection 12 moves in direction 49 to engage lobe 24 and rotate disc 23 to an unswitched position so that switch 26 turns off the left lamps. The turn signal may also be manually cancelled by energising solenoid 19 again to ratchet its disc 23 to an unswitched position. A corresponding arrangement of push button switch (32), (Fig 3), solenoid 38, cam disc 23, microswitch 29, lever 27, linkage 52, 16 and projection 13 on arm 10, operates to select and cancel a right hand signal. <IMAGE>

Title: "Fabrication process for microminiature cathode"
Inventor: OKANIWA KAZUHIRO
IPC: H01J9/02
Filed: 1991-01-23
Abstract: A process is disclosed for fabricating an electron emitting vacuum type device having a tipped electron emitter (28) supported on a substrate (21) and disposed in a vacuum for emitting electrons. The process utilizes a substrate having opposed substantially planar front and rear surfaces. The front surface, carrying a series of conical depressions, is plated with a metallic layer (26) of electron emitting material which lines the apertures to form metallic structures having tips buried in the substrate. A first material removal process, comprising grinding, is performed on the rear of the substrate to remove the bulk of the substrate but leaving the tips protected within the substrate. A second operation is then applied to the rear surface to advance the plane of the rear surface to expose the metallic tips. The second operation employs a wet etching solution, and may employ mechanical friction (free of abrasive particles) to assist the speed of etching and uniformity of the finished surface. <IMAGE>
