Title: Tools for connecting wires
Inventor: BASKERVILLE MARTIN WILLIAM
IPC: H01R43/01
Filed: 1984-10-01
Abstract: A tool for inserting a wire into an insulation displacement type pin fork connector 20 consists of two members 14, 16 spaced apart sufficiently to straddle the connector 20 and a thin web 18 connecting the members 14, 16. The web 18 is thin enough to pass between the forks of the connector so that when a wire 26 is inserted into the connector 20 pressure is applied over the whole length of the wire 26 and the risk of the wire 26 being broken by the connector 20 is reduced. Thus the tool is particularly suitable for wires made from weaker materials such as aluminium wires. <IMAGE>

Patent GB-2151845-A (GB)
Title: A semiconductor memory
Inventor: YAMAGUCHI MASAO
IPC: H01L23/495
Filed: 1984-11-23
Abstract: A lead frame (4) used for producing the power transistor has guides (6a, 6b) supporting a header during a resin-molding step. A V-shaped groove (13) is formed at a cut portion of each guide in such a fashion that it is exposed further inward than the outer wall of a resin package after the resin molding. The V-shaped grooves can provide a power transistor which has a high degree of moistureproofing. Since the cut portions of the guides, that is, the positions of the V-shaped grooves, are further inward than the outer wall of the resin package, a power transistor with a high withstand voltage can be obtained. <IMAGE>

Title: Ionospheric sounding system
Inventor: WILKINSON ROBERT GRAHAM
IPC: H04B17/00
Filed: 1985-10-11
Abstract: For frequency management of HF communications between a transmitter and a remote receiver, the system makes use of code-modulated narrow band sounding pulses transmitted at frequencies throughout the HF band. The code has an impulsive auto-correlation function and the frequency selection is pseudo-random. The code may be a two-part complementary code. Alternatively the code may be a selected one of a family of codes possessing high auto-correlation and low cross-correlation properties, thereby enabling communications management information to be conveyed by the choice of code. Measurements of signal and noise are made at the receiver for each transmitted frequency to assist establishing a HF communications link. Synchronous detection of the received signal is used, employing correlators (803, 804) in phase quadrature. <IMAGE>

Patent GB-2179588-A (GB)
Title: Production of mouldings
Inventor: BECKER GUNTER
IPC: B28B17/00
Filed: 1986-08-27
Abstract: The production of mouldings, for example concrete blocks, with uniform bulk density and accurate dimensions is achieved by measuring the block height and weight of the demoulded mouldings and by calculating the bulk density from these two values. If variations from the desired values occur, the filling level is immediately altered. Both measurements are carried out outside the vibration area so that precision measuring instruments can be used. To eliminate the influence of different board heights, the board upper side and the block surface is sensed and the difference determined. The procedure for determining block weight is such that the board with the blocks thereon is weighed and the known board weight is subtracted as the constant.
Patent GB-2196777-A (GB)
Title: Automatic reverse mechanism for tape recorder
Inventor: TANAKA SHINSAKU
IPC: G11B15/093
Filed: 1986-10-02
Abstract: Responsive to the stop of left-hand reel shaft 1b by full take-up of a magnetic tape thereon, a contact portion 33b of a cam follower 31b is separated from a cam surface 11b and a cam 12b is brought into contact with the contact portion 33b. A turnable lever 7b is hence caused to turn counterclockwise so that a gear 9b is separated from a gear 26b to interrupt transmission of the rotary force of a capstan 3b to the gear 26b. At the same time, a hook member 24 is caused to turn clockwise so as to allow a changeover bar 17 to return rightwards. As a consequence, a right-hand pinch roller 4a is pressed against a capstan 3a while the left-hand pinch, roller 4b is separated from the capstan 3b. A right-hand turnable lever 7a is pulled counterclockwise by a spring 27a, whereby a gear 9a is brought into meshing engagement with a gear 26 to drive the magnetic tape rightwards. <IMAGE>

Title: Process for the harmonisation of a day/night firing system for a missile guided by a laser beam
Inventor: LOY FERNAND
IPC: F41G7/26
Filed: 1986-11-03
Abstract: Harmonization process for a day/night missile firing system in which the day channel includes a day telescope (1) (3), a laser beam guidance transmitter (7) (9), and a collimator/deviation measurer (10) (12) and (13) and the night channel includes a heat camera (17) (18). The harmonization of the guidance transmitter is carried out permanently by returning part of its emitted flux into a deviation-measuring receiver (14) by means of separators (16) (15) and (13). The harmonization of the heat camera is similarly obtained permanently by means of the invariant trihedron subassembly (19) (20) which returns the infra-red flux in the focal plane (18) of the camera. The infra-red image of the reticle of the collimator is thus superimposed on the image of the reticle of the terrain. The eyepiece of the day telescope is used for the observation. The IR reticle is projected in the heat camera at a wavelength shorter than the main operating band. <IMAGE>
Patent GB-2202706-A (GB)
Title: Video signal processing
Inventor: BORER TIMOTHY JOHN
IPC: H04N5/213
Filed: 1987-03-27
Abstract: An input video signal is delayed by two cascaded picture delays 10, 11. The undelayed and 2-picture delayed signals are processed by interpolators 13, 14 to produce compensated signals in which moving objects are subjected to such relative delays that the moving objects register in the two compensated signals and the 1-picture delayed signal. These three signals are fed to a median selector 12 which selects the median value and thereby temporally filters the video signal in such a way as to remove impulse noise, e.g. arising from scanning dirty film. The interpolators 13, 14 are controlled in dependence upon motion vectors describing movement for each pixel and derived from the input signal by a motion measurement unit 16 or received along with the input video signal in a digitally assisted television receiver. <IMAGE>

Patent GB-2215880-A (GB)
Title: Variable length data field processing
Inventor: BALDWIN DAVID ROBERT
IPC: G06F9/26
Filed: 1988-03-23
Abstract: A numeric processing subsystem which has a dedicated data-transfer processor running concurrently and asynchronously with other processors. When accessing data generated externally (or at the interface controllers) which has less than the internal data width (32 bits), the top bit of the data is preferably replicated in hardware to fill the field. When a source is selected, such as the address generator 230 address port or data port, which drives only the lower sixteen bits, the sign/zero extend PLA, 216, is also activated so that the data are either sign-or-zero-extended up to the bus width of thirty-two bits. This provides correct sign and xero extension. This capability permits the 32-bit programming environment to dispose with word-instruction or byte-instructions. <IMAGE>
