Patent GB-2074415-A (GB)
Title: Computed tomography with selectable image resolution
IPC: G06T1/00
Filed: 1981-04-02
Abstract: A computed tomography system x-ray detector has a central group of half-width detector elements and groups of full-width elements on each side of the central group. To obtain x-ray attenuation data for whole body layers, the half-width elements are switched effectively into paralleled pairs so all elements act like full-width elements and an image of normal resolution is obtained. For narrower head layers, the elements in the central group are used as half-width elements so resolution which is twice as great as normal is obtained. The central group is also used in the half-width mode and the outside groups are used in the full-width mode to obtain a high resolution image of a body zone within a full body layer. In one embodiment data signals from the detector are switched by electronic muitiplexing and in another embodiment a processor chooses the signals for the various kinds of images that are to be reconstructed. <IMAGE>

Title: Pneumatic ejector device for cigarette rods
IPC: A24C5/34
Filed: 1981-05-07
Abstract: A pneumatic ejector device is provided for expelling when required cigarette rod lengths from the through duct of a detector unit in which the weight of tobacco filter per unit length of a continuous cigarette rod is sensed. The ejector device comprises an annular pneumatic ejector nozzle located at the inlet of the through duct of the detector unit. The nozzle is fed from an air feeding line, which is adapted to be temporarily connected, through a controllable intercepting means, with a source of air at a relatively high pressure, whereby an air jet is blown from the nozzle, strong enough for expelling from the said through duct of the detector unit and from the adjoining outlet duct, any broken-off cigarette rod lengths which remain therein, owing to incorrect manual insertion of a cigarette rod or accidental stopping of the cigarette-making machine.   <IMAGE>

Title: Valve assembly for use with high temperature and high pressure fluids
Inventor: DE FEO ANGELO
IPC: F16K27/02
Filed: 1981-11-03
Abstract: Inner and outer spaced shells (12, 16) have a valve actuator support (18) connected at its end portions. A layer of resilient heat insulating material (66) covers the outer surfaces of the inner shell (12) and an inner actuator support member (38) only occupies part of the spaces between the inner and outer shells (12, 16) and inner and outer actuator support members (38, 40). The remaining portion of the space between the inner and outer shells and a space between inner and outer support members is filled with a castable, rigid refractory material (68). A movable valve member (22) is disposed in the inner shell (12). A valve actuator assembly (54) extends into the inner shell (12) for actuation of valve member (22). An anchor means (72) is attached to the inner shell so that relative radial movement between the inner and outer shells (12, 16) is permitted by the layer of resilient material (66) and relative longitudinal movement of the inner shell to the outer shell is permitted to thereby maintain the functional integrity of the movable valve member. <IMAGE>

Title: Buffer storage apparatus
IPC: B65G47/51
Filed: 1981-12-22
Abstract: A buffer storage apparatus comprises means for removing a product travelling from one location to another, and an elongate reservoir belt movable in the direction of its elongation from a stowed position wound on a spool, past the removing means to receive the product and thereafter to a product storage position where the charged reservoir belt is wound on a further spool.

Title: Fibre-optic switch
Inventor: WILSON DAVID
IPC: G02B6/35
Filed: 1982-04-29
Abstract: A fibre-optic switch comprises a diaphragm (1) of magnetically soft material sealed in a capsule. The face of the diaphragm (1) can be highly polished so as to have good reflectivity. An optical fibre (9) terminated in a ferrule (8) is sealed into a tube (2) which may be magnetic, and which is on one side of the diaphragm (1) with the fibre end near to the diaphragm (1). Light from the fibre (9) is reflected back thereinto and is modulated in accordance with the movement of the diaphragm (1). Alternatively the ferrule (8) contains two adjacent fibres, one used as a transmitting fibre and the other a receiving. The fibres may be non- parallel, enhancing the optical coupling between the fibre ends. The magnetic field can come from a coil or movable permanent magnet. In one version the magnet is a rotatable disc with alternate N and S poles on its rim. This can be used as the movable element of a flowmeter. <IMAGE>

Title: A meter panel
Inventor: SHANKS IAN ALEXANDER
IPC: G09G3/18
Filed: 1982-09-17
Abstract: In a meter panel, e.g., for a car dashboard, comprising electrode- bearing plates (5, 7) each side of an electro-optic medium (3)-a liquid crystal, a luminescent solid, or a rarified gas, the electrodes (9, 11) in register define by their overlap a number of meters (15A and B; 17A and B), the electrodes (11) on one plate (7) being interconnected from meter (15B) to adjacent meter (17B). Isogonal signals are applied to the electrodes (11) common to each meter. For each meter one signal is selected and also applied to one of the opposite electrodes (9) while a signal isogonal to the applied signals is simultaneously applied to the remaining electrodes (9). The medium is thus driven ON except at regions where the registered electrodes have like signals applied. These regions appear in contrast against the background, to give index display. <IMAGE>

Title: Improvements in anti-runback devices for conveyors
Inventor: HOPKINS JOHN EDWARD
IPC: B65G23/26
Filed: 1982-12-24
Abstract: A wormgear housing (10) of a back drivable wormgear (14, 15) is mounted on the conveyor frame. The conveyor headshaft (32) carries the inner race of a sprag clutch (31) mounted within the wormwheel (15). The wormshaft (13) is provided with a multiplate brake. The brake normally prevents backdriving of the wormgear but in the event of jamming of the conveyor, tension in the conveyor belt is releasable under control of the brake. An alternative embodiment employs an irreversible wormgear which is driven to release conveyor belt tension in the event of jamming of the conveyor. <IMAGE>

Title: Combined braking and steering brake system for vehicles
Inventor: HAAR LUCAS HEINZ
IPC: B62D11/08
Filed: 1983-01-21
Abstract: In this brake system, there are provided for the purpose of braking a driven vehicle wheel for each of two oppositely lying vehicle sides a brake pedal (3, 4), a tandem master cylinder (1, 2) actuated by the latter, as well as a first brake (19, 20) connected to the push-rod circuit of the tandem master cylinder. The push-rod circuits of both tandem master cylinders (1, 2) are interconnected via a connecting line (21). Branching off from the connecting line (21) is a line which leads to second brakes (23, 24) meant for braking a non-driven vehicle axle. This arrangement enables without any additional valves to independently actuate a first brake (for steering) by depression of the assigned brake pedal and to simultaneously actuate the first and second brakes with full pressure compensation by the simultaneous depression of both brake pedals. The brake system can be used for braking and assisting steering of an agricultural tractor or combine harvester. <IMAGE>

Title: Keyboard with membrane switch array
Inventor: ELLSON ALLAN
IPC: H01H13/705
Filed: 1984-03-29
Abstract: Pressure is selectively applied to the upper membrane (112) of a membrane switch by means of a switch actuating key (110) via a spring (104). The spring has a first portion which 104 extends from a supported end of the spring to a bend (107) in a plane parallel to the plane of the upper membrane, and a second portion which extends upwards, at an angle, from the bend (107) to a free end. When the free end of the spring (104) is flexed downwards by the key (110), the spring hinges about its supported end, whereby the bend (107) applies pressure on the upper membrane (112). The spring (104) may be integral with a channel section member supporting the key (110) or may be supported by means of a dog-leg portion which is entered into a vertical slot (106) provided in a key housing (101). The slot contains facing ribs which cause the dog-leg portion to flex as it is pushed into the slot. <IMAGE>
