Patent GB-1292189-A (GB)
Title: Improvements in or relating to apparatus for non-contact determination of the level and profile of objects
Inventor: AFANASIEV VADIM NIKOLAEVICH
IPC: G01F23/28
Filed: 1970-12-15
Abstract: 1292189 Determining profiles photoelectrically TSENTRALNY NAUCHNO-ISSLEDOVATELSKY INSTITUT CHERNOI METALLURGII IMENI I P BARDINA 15 Dec 1970 59473/70 Heading G1A In an apparatus for measuring the level or profile of a surface, e.g. the stock level in a blast furnace, in which a servocontrolled radiation source 4 illuminates an illuminated zone 3 and a collimated servocontrolled detector arrangement 8 views a viewed zone 9 comprising two sub-zones 10, 11 either one of the source and the detector arrangement scans a predetermined pattern across the surface and the other follows this movement in response to any "zone misalignment" signal generated by the detector arrangement. As shown γ-radiation from the source 4 is received by two scintillation detectors 14, 17, each output then being amplified 20, 21 freed from noise 22, 23, shaped to suitable form 24, 25 and integrated 27, 28 before being supplied to a differential amplifier 33. With the source scanning in a predetermined manner over the surface, the differential amplifier output represents in magnitude and sign the amount and direction respectively of the misalignment between the centre 56 of the viewed zone 9 and the centre 55 of the illuminated zone 3. If the viewed zone is leading the illuminated zone, the amplifier output is merely used to supply a pivoting adjustment to the detector arrangement 8. However, if the viewed zone lags behind the illuminated zone, the amplifier output is operative both to effect a pivoting correction to the detector arrangement, and also to slow down the scanning speed of the source 4. Alternatively, the detector arrangement may scan the surface in a predetermined manner, in which case the above-described servocontrols of the detector arrangement and source are interchanged. In another embodiment Fig.2 (not shown) both the detector arrangement and source are initially set to scan at predetermined speeds. The output from the differential amplifier 33 is then used, in accordance with its polarity, to slow down the scanning rate of whichever scanning element is leading at a particular instant.

Patent GB-2024294-A (GB)
Title: Improvements in and relating to channel-shaped sealing strips
IPC: B60J10/00
Filed: 1978-06-30
Abstract: The strip disclosed has a channel-shaped metal carrier (5) which is embedded in synthetic plastics or rubber material (6) which defines inwardly directed gripping ribs (10, 12). A thin layer (8) of heat-responsive material is placed on the inside surface of the material (6). The strip is then placed over an edge flange (14) which is to be protected against corrosion. When the strip is subjected to externally applied heat, at an enhanced temperature which is not sufficient to damage the material (6) embedding the carrier (5), the heat-responsive material (8) expands so as to fill the space between the strip and the flange (14) and to become tacky so as to seal and stick to the flange (14). Alternatively the material (6) is itself heat-fusible. Strips according to the invention are particularly suitable for protecting parts of vehicle bodywork against corrosion. <IMAGE>

Title: Method of and apparatus for examining objects by the use of radiation
IPC: G06T1/00
Filed: 1978-10-02
Abstract: A method and apparatus for processing attenuation data to produce a tomographic image requires only that each point within a patient scan circle 20 be viewed from 180 DEG  in order to produce a full set of data. Data from views beyond 180 DEG  are redundant and do not improve the image quality. Scanning is effected by an X-ray source and detector arrangement in which the X-ray source 16 provides a fan-shaped beam or swath of X-rays and the detectors 12 are arranged about the scan circle 20 for 180 DEG  plus approximately the angle 22 of the fan-shaped beam. A back projector 44 back projects data from a polar coordinate system into a rectangular coordinate system in which the matrix points in the rectangular coordinate system can be loaded sequentially with the appropriate density value from a data line expressed in the polar coordinate system. <IMAGE>

Title: Document handling apparatus
IPC: G03B27/62
Filed: 1978-10-11
Abstract: A document handling apparatus, for use with a machine to copy either thin or thick documents includes two pairs of cooperating rollers 16a, 16b, 17a, 17b located on top of the machine; these feed thin documents past an illuminating station 24. A carriage 14 for supporting a thin or thick document is also located on top of the machine. For copying a thick document or for making multiple copies of a thick or thin document, the two pairs of rollers move out of the path of the carriage which travels across the illuminating station. The carriage is centered on its home position by a cam which is part of a slider bracket supporting structure, manually or automatically raised and lowered. The rollers and the carriage are independently driven by the main motor of the machine. Controls prevent the carriage from travelling too far in either direction and from moving when the rollers are in its path. <IMAGE>

Patent GB-2048531-A (GB)
Title: Keyboard especially for telephone
IPC: H03M11/24
Filed: 1979-05-01
Abstract: A keyboard, e.g. for a telephone, relies on a lever-ratio principle. In its simplest form it has a stiff member (1) of strip-like form which carries a set of push-buttons (4) integral with the strip. At its ends the strip is supported by two pressure-sensitive transducers (2,3). When a button is depressed both transducers give outputs and the ratio of these outputs depends on the distances from the transducers to the depressed buttons. Electronic circuitry associated with the transducers interprets the ratio of the transducers' outputs and uses that ratio to generate output signals, e.g. to send a digit signal to a remote exchange when the device is used in a telephone. Variants described include ones with a triangular stiff member supported by three transducers and bearing a set of push-buttons arranged in a coordinate array. <IMAGE>

Title: Pressure Surge Relief System
IPC: F17D1/20
Filed: 1980-02-15
Abstract: A pressure surge relief system for a liquid transporting pipeline (12) comprises a surge relief line (14) adapted to be tapped at one end from the pipeline and connected at the other end to a receptacle (26). A valve (16) in the relief line is conditioned to open quickly to substantial flow when the pressure in the line exceeds a predetermined safe limit.
