Title: Method for assembling travelling wave tube
Inventor: TERESI JOSEPH ANTHONY
IPC: H01J9/18
Filed: 1989-04-11
Abstract: A method for assembling a travelling wave tube (TWT) includes the step of forming at least one heat stripe 38 along the metal barrel 12 of the TWT to reduce the diameter of the barrel 12 and create an interference fit between the barrel 12 and internal components of the TWT. A laser beam 34 or an electron beam may be used to form the heat stripe or heat stripes. The material in the heat stripe is melted or plastically deformed, and on cooling, the thickness of the barrel increases at the heat stripe and the internal diameter of the barrel is reduced. The TWT comprises a helix (14, Fig 4) and three T-shaped rods (16) located in the barrel 12. <IMAGE>

Patent GB-2228460-A (GB)
Title: Rear-wheel steering system for four-wheel steering vehicle
Inventor: TAKAHASHI AKIRA
IPC: B62D7/15
Filed: 1989-12-18
Abstract: The steering system is of the kind having a front-wheel steering angle sensor (9), and a vehicle speed sensor (10), which send signals to a control unit (11) for the electric motor (12) which steers the rear wheels. In principle, the rear wheels assume a neutral position when the front wheel steering angle is zero but in practice true neutral running of the vehicle may require a small non-zero front wheel steering angle e.g. due to tyre wear or suspension misalignment. The control unit (11) therefore includes a front-wheel neutral point correction means (19) which corrects the zero point of the signal from the front wheel steering angle sensor (9) in response to a zero signal from a further sensor (26) which detects front wheel steering force, front wheel lateral force or the lateral acceleration of the vehicle.

Patent GB-2240131-A (GB)
Title: Rotatable badge fastening
Inventor: FATTORINI THOMAS PETER
IPC: A44C3/00
Filed: 1990-01-19
Abstract: A fastener (1) has a crocodile clip (3) attached to a plate (4) mounted on its "unseen" side by way of a rotating boss (5). The clip (3) is attached to the plate (4) through a slot in the boss 5. Because the boss 5 is able to rotate the plate (4), displaying a name or the like, it may be oriented so as to always point the correct way up. This arrangement overcomes the problem of existing fasteners and badges, to the extent that existing fasteners wore not capable of being used on both lapels, or they did not remain in the orientation intended. In a preferred embodiment locating means are provided to lock the boss (5) into one of several predetermined positions so that the plate (4) or badge is always displayed at the correct angle. <IMAGE>

Title: Component stripping apparatus
Inventor: HUNTER VICTOR STEPHEN
IPC: B23D31/00
Filed: 1990-08-20
Abstract: Apparatus for stripping components from a board, comprises a pair of spaced shear jaws (6, 7), a clamp (3, 4) and hydraulic means (1, 2) for moving the clamp (3, 4) relative to the shear jaws (6, 7). In use a board is inserted between the shear jaws (6, 7) and secured by the clamp (3, 4). The clamp (3, 4) is then moved away from the shear jaws (6, 7) so that the board is pulled between the shear jaws (6, 7) and any components mounted thereon sheared off. Alternatively the clamp is stationary and the jaws are moved. The upper jaw 6 is urged towards jaw 7 by springs (18, Fig. 3), clamp 3 is actuated by hydraulic cylinder means (11, Fig 2) and spikes 9 projecting from clamp 3 to grip the board cooperate with through holes 10 in clamp 4. An accessory comprising a hydraulically-driven member (25 Fig 4) running in a guide (26 Fig 5) on a table (21) which has guides (23) and clamps (27) is used to strip one edge portion of the board to aid its insertion between the jaws 6 and 7. <IMAGE>

Title: Developer roller in an image forming apparatus
Inventor: SUGIHARA KAZUYUKI
IPC: G03G15/08
Filed: 1990-10-19
Abstract: A developing roller constitutes part of one of a plurality of developing units in a color developing device in which develops latent images electrostatically formed on a photoconductive element, each image being developed by a magnet brush formed by the developer of particular color on associated one of the developing rollers. Each developing roller has a non-magnetic conductive base (18Y1), a first insulating layer (18Y2) formed on the base and having an insulation resistance greater than 10<6> ohms e.g. 10<9> ohms, and a second conductive layer (18Y3) formed on the first layer and having an insulation resistance lying in the range of 10<4> ohms to 10<9> ohms e.g. 10<6> ohms. Conductive layers (18Y1) and (18Y3) are connected at (18Y4) to dissipate any static electricity formed in insulating layer (18Y2). This developing roller prevents bias being applied thereto for development from leaking due to scratches or similar defects of the photoconductive element. While the developing device is in operation, a magnet brush is prevented from being formed on the developing rollers of those developing units which are not joining in the development. Alternatively the roller may form part of the cleaning unit. <IMAGE>

Patent GB-2258780-A (GB)
Title: Target recognition and location
Inventor: SUTTON PHILIP
IPC: G01S3/786
Filed: 1992-07-02
Abstract: An optical correlator responsive to targets independent of scale receives radiation from a field of view on the write face of a spatial light modulator 12 which is illuminated in its read face by a polychromatic light source 13, e.g. a multi-line Krypton-Argon gas laser or a white light source. A coherent Fourier transform of the field of view is then formed in a correlation plane on a single matched spatial filter 16 on which is recorded a Fourier transform image representative of the target at a preselected wavelength. Light transmitted by the filter means then provides an indication of the presence of the target. Information in the correlation plane is preferably sampled within different spectral intervals to detect the spectral interval corresponding to a peak of correlation from which the target size and hence range can be obtained. The multi- spectral processing may be done by scanning the optical spectrum at the source plane by means of an acousto-optic cell which scans the spectrum. <IMAGE>

Title: Colour television display projection device
Inventor: LEWIS MEIRION FRANCIS
IPC: H04N9/31
Filed: 1992-07-09
Abstract: A colour display device (10) incorporates three light sources (12) supplying red, green and blue light respectively. A spatial light modulator (20) is positioned to provide time varying selective blocking of light from the sources (12) under television signal control. Light passes from the sources (12) to a condenser lens (16), then through a liquid crystal display element (22) and a projection lens (18) before reaching a screen (30). The display element (22) is also under television signal control. Signals supplied to the display element (22) provide for successive sets of three frames to be displayed, each set incorporating frame information to be displayed as red, green and blue and combinable to form a coloured frame. When the element (22) displays a frame corresponding to one of the three colours red, green and blue, the modulator (20) transmits that colour and blocks the others. The screen (30) receives a colour image in which red, green and blue are displayed successively for each frame.
