Patent GB-2174573-A (GB)
Title: Radio telephone system
Inventor: BEESLEY GRAHAM EDGAR
IPC: H04B7/005
Filed: 1985-05-01
Abstract: In communications apparatus, particularly cordless telephone sets, there is a need to maximise the number of communication links that can be made from a given area or volume. This is achieved by reducing the transmit power of a transceiver Y below its maximum in response to a signal level 50 of existing users V on that channel, as measured by the transceiver Y that is setting up a call. In particular, the reduction in transmit power p' is dependent on (e.g. equal to) the amount p by which the power of existing users exceeds a predetermined lower threshold TL. <IMAGE>
Patent GB-2161669-A (GB)
Title: Television systems
Inventor: HURST ROBERT NORMAN
IPC: H04N7/00
Filed: 1985-06-20
Abstract: In a compatible high definition TV system, the image is sinuously scanned by taking consecutive pixels alternately from two scan lines. The rate of selection from each line is an even multiple of the line rate, with phase inversion on alternate frames. The resulting high definition signals is sent directly to an appropriate high definition monitor (1012). Alternatively, they are low passed filtered in a filter (1010) to produce low definition signal compatible with a normal standard monitor (710). To reduce bandwidth the low definition signal is subtracted (1014) from the high definition signal to produce difference signals ( DELTA ) which may be inserted into the blanking intervals. In the high definition monitor the difference signals are added (1018) to the low definition signals to reconstitute the high definition signals. Production of the difference signals may be inhibited where there is motion in the image. The specification discloses systems with and without bandwidth reduction, cameras, monitors, and analogue and digital signal processing techniques. <IMAGE>

Title: Adjustable sling type curtain header hanger
Inventor: SALES ALAN CHARLES
IPC: B65D63/10
Filed: 1985-06-26
Abstract: An adjustable "sling" type hanger for the storage of a pleated curtain has two different lengths of plastic strapping (B) and (C), which are pivotally connected together. The longer strap (B) is threaded through loops at the ends of the shorter strap (C) to form a choker loop around the head of the pleated and finished curtain. The curtain is thus secured by virtue of the configuration and inherent properties of the material used, in conjunction with its self-locking ability due to friction. The loop formed by the shorter strap (C) is used to support the curtain from a selected point of hanging (normally a hook). <IMAGE>
Patent GB-2164481-A (GB)
Title: Audio and video recording technique
Inventor: KEEN THOMAS CLAUDE HENRY
IPC: G11B20/00
Filed: 1985-07-22
Abstract: A method of producing recordings of an information signal which cannot be re-recorded on a tape recorder without unacceptable contamination by beat frequencies generated from signals recorded, together with the information signal, on the genuine recording. This is achieved by mixing, with the desired information signal, a number of signals above the audio frequency range which, upon playback, interfere with one another to produce beat frequencies in the vicinity of the bias frequency of a tape recorder. These beat frequencies interfere with the bias frequency and produce fresh subtractive beat frequencies which are in the audio frequency range. Apparatus for producing the contaminating signals comprises a set of oscillators (11, 111, 211) the output signals from which are combined via variable resistors at (17) and (31) to produce an output signal which contains not only the original oscillators signals but also beat frequencies at the sum and difference of all the oscillators. <IMAGE>

Title: A device for applying an impact
Inventor: DODGE THOMAS WILLIAM
IPC: E21B1/02
Filed: 1985-12-10
Abstract: A device for applying an impact has a main impacting body 1 having a blind bore 2 internally shaped to correspond to the cross section of the object (e.g. posts) to be driven into the ground. The body 1 is provided with arms 4 to enable the operator to reciprocate the device over an upper length of the object to effect the driving process. The device is extremely useful in driving angle-iron fence posts for example, where the use of an ordinary hammer tends to damage the top of the post and maintenance of verticality is difficult. The device conveniently removes these problems. For driving in angle-iron posts the impacting body 1,which is made of metal, is formed in the shape of 90 DEG  angle-iron. The opening to the bore 2 terminates in advance of the end E of body 1 to form a positioning lip L which is used to position the device on the top of the post. <IMAGE>

Title: Television receiver
Inventor: FORD PETER BRADEN
IPC: H04N5/44
Filed: 1986-01-28
Abstract: A television has a holder 1 whose interior forms a tray to accommodate a remote-control unit, the holder 1 being pivotably mounted on a support plate 2 via a pivot pin 3 and co-operable recess 4. The support plate 2 is bolted against the interior surface 5 of the television receiver front panel 6. The television receiver has a catch arranged to fasten the holder 1 in the illustrated position. When this catch is released, a spring at the pivot pin 3 and recess 4 urges the holder to rotate towards a position in which it lies in the aperture of panel 6 with the tray accessible. As holder 1 rotates in this fashion, a toothed wheel 8 which is rotatably mounted on holder 1 engages with a toothed track 9 on sidewall 10 of plate 2 to provide a frictional damping effect. <IMAGE>

Title: Thermoelectric energy conversion
Inventor: ASPDEN HAROLD
IPC: H01L35/28
Filed: 1989-11-16
Abstract: A thermopile 30 comprises a stacked assembly of bimetallic layers in which there is full conductor interface contact over the distance separating hot and cold surfaces 31, 32. The assembly may include dielectric layers forming a capacitor stack. A.C. current through the stack is matched in strength to the Seebeck-generated thermoelectric current circulating in each bimetallic layer. The resulting current snakes through the stack to cause Peltier cooling at one heat surface and heating at the other. A.C. operation at a kilocycle frequency enhances the energy conversion efficiency as does heat flow parallel with the junction interface. <IMAGE>

Title: Die eject unit
Inventor: WRIGHT ROBERT JAMES
IPC: H01L21/683
Filed: 1989-12-07
Abstract: A die eject unit comprises a die eject head (1), comprising a disc (2) with a central hole (3), a housing (4) for the disc and a die eject needle (5) located within the housing (4) and movable from a first, non-operative position, to a second, operative position, in which operative position the tip of the needle projects through the central hole in the disc. The die eject unit further comprises means for holding down under vacuum a die presentation system on the disc and means for controlling the movement of the die eject needle from its first, non-operative, position, to its second, operative position, and preventing the needle from assuming its operative position until the die presentation system is held down on the disc. The means for controlling the movement of the die eject needle is directly interlocked with the means for holding down the die presentation system so that the needle cannot assume its operative position before the die presentation system is held down under vacuum. Vacuum applied at (8) holds down the die on a tacky film on sintered disc (2) and as vacuum increases, diaphragm (11) is raised against the bottom of needle mounting (6) causing it and needle (5) to rise against the bias of spring (7). <IMAGE>

Abstract: A striker plate has a body of channel form with a rectangular opening (16) therein adjacent one longitudinal edge of the body which is a front edge when the body is fitted to a door frame, in use. At the opening is fitted a pivotable element (17) which has front and rear flat surfaces (19, 21) respectively, the front surface (21) substantially closing the opening in one position of the element and lying flush with a front surface of the body, the rear surface (21) in another position of the element lying below the level of the front surface of the body and terminating short of a longitudinal front edge of the opening to define a recess for a latch bolt of a door secured to the door frame, in use. A thumb-wheel (35) is manually operable at the front surface of the body to pivot the element (17) between said two positions, and a spring plate (37) at the rear of the body acts to oppose such movement of the element. The latch bolt cannot lock the door when the element (17) is in said one position. <IMAGE>
