Title: Telephone in use indicator (line busy lamp)
Inventor: HENDERSON PETER
IPC: H04M1/82
Filed: 1984-02-15
Abstract: An opto-electronic device, which by the electrical connection to both legs of a line, will indicate whether an extension telephone set on the same line is in use. The device consumes negligible line current both in lit mode and unlit mode, requires no additional power source nor any modifications to be made to installation nor to the circuit of any telephone or similar Telecom equipment into which it will be fitted. The light output can be constant or by inclusion of a flasher circuit made to pulsate. The device functions by using a voltage dependant switch Q1, Q2 to turn the LED on when the line voltage drops due to the line being loaded (used), regardless of where on that line it is being used or however many other line status indicators are fitted into other extensions, phones with or without this device fitted can be freely mixed on each line. <IMAGE>

Title: Video cassette security device
Inventor: DUNNE CECIL THOMAS
IPC: G11B23/04
Filed: 1984-04-16
Abstract: A video cassette security device 10 is in the form of an insert which has radial teeth 12 which engage in the corresponding spaces of a video cassette spool in an interference fit. The insert has a central bore which tapers inwardly away from the spool. The insert prevents unauthorised playing of the video cassette and cannot be removed without the use of a co-operating key except with great difficulty and considerable risk of damage to the cassette. The key (not shown) has an elongate barrel which is provided adjacent one end with lateral retractable balls which partially project through openings in the side of the key barrel. The diameter of the barrel is such that the balls must be retracted to allow insertion of the end of the barrel in the insert bore. To remove the insert, the balls are retracted, the key end is inserted in the insert bore and the balls are then returned to their original, projecting position to prevent withdrawal of the key from the insert bore. Pulling on the key then draws the insert from the cassette spool. <IMAGE>

Title: Jointed, reinforced, elastomer-coated fabric material
Inventor: SHINMI HIDEO
IPC: B29C65/72
Filed: 1984-05-31
Abstract: A jointed watertight, airtight, elastomer-coated material is described. The material consists essentially of a first elastomer-coated fabric material and a second elastomer-coated fabric material, said second material being overlaid at an edge over an edge of the first material. The overlaid portion of each material is laminated to the other with a pressure-sensitive adhesive intercalated between the two materials. The laminated portion is further bound with a fastener which penetrates across the laminated portion in an up-and-down manner. Typical fasteners are thread, rivets, or bolts. The jointed material can be further bound by a tacky tape which is adhered on the bound portion of one material and the unbound portion of the other material, covering the joint between the edges of the two materials. The jointed waterproof, airtight, elastomer-coated fabric material is particularly useful for air-supported structures.

Title: A high voltage pulse generator
Inventor: GRAY DAVID REYNOLDS
IPC: H03K3/57
Filed: 1985-02-20
Abstract: A high voltage pulse generator is provided for use with an electric fence, which overcomes the problem of generators known heretofore, whereby the energy which can be delivered onto an electric fence falls off as the resistance on the line increases. The generator comprises a transformer (2) having a secondary coil (3) and primary coil (4), the charge is delivered from the secondary coil (3). A pair of primary capacitors (10 and 11) are connected across the primary coil (4) and with the coil (4) form an oscillating circuit (12) which causes the capacitors (10 and 11) to continuously discharge and charge, thereby increasing the energy which may be delivered onto the fence line. The circuit (12) is opened and closed by a triac (14) which is controlled by timing circuits comprising a resistor (23) and a capacitor (24), and a resistor (28). An AC supply is delivered to the capacitors (10 and 11) through a rectifying circuit with diodes (18 and 19). <IMAGE>

Title: Board game simulating golf
Inventor: PINKNEY KENNETH GEORGE
IPC: A63F3/00
Filed: 1985-02-26
Abstract: A game which simulates the game of golf with players moving markers along a grid of drilled holes in a transparent Playing Board which is sequentially placed in registration above various reference cards which display images illustrating the characteristics of the eighteen golf 'holes' across which play may proceed. Calculation of the number of spaces markers are to move is, within certain limits, variable at the discretion of each player, who may manipulate the face value of three dice, using any of seven approved methods of arithmetical calculation, either separately or in combination, but not using each figure more than once. It may be played by one or more competitors playing as individuals, or in teams, and encourages mental agility with figures, whilst teaching an understanding of the Rules of Golf and an appreciation of the code of ethics and etiquette intrinsic to the game of golf.

Patent GB-2163312-A (GB)
Title: Amplifier
Inventor: BLOMLEY PETER FRED
IPC: H03F3/183
Filed: 1985-03-07
Abstract: This describes an amplifier used in a telephone tone ringer chip, usable, inter alia, in the "chip set" of our Application No. 8317706. The present chip includes tone generation circuitry, which can produce several different tone combinations under control of selection inputs, and also has a speed input and a loudspeaker drive output. When the amplifier is used in the telephone application, it acts as a speech amplifier when off-hook and when a loudspeaking facility is being used. When on-hook the amplifier acts as a tone amplifier. To do this, its input stage includes two differential amplifiers, one (T118-T119) for tone and one (T117-T120) for speech, only one of which is enabled at any one time. The outputs from these two amplifiers go via a common amplifier (T125-T126) to an output amplifier (T134). <IMAGE>

Title: Transport and checking apparatus for prawns
Inventor: PETERS MANFRED
IPC: A22C29/02
Filed: 1987-09-03
Abstract: Transport and conveying apparatus for prawns comprises conveying equipment (1) for prawns and a feeler device (8) with a feeler element (10) which is pivotably mounted to rotate about an axis (12) parallel to the path of the prawns and which is cyclically lowered onto the prawns before conveying on for processing. That part of the feeler element (10) which comes into contact with each prawn is in the form of a feeler edge (11), which extends transversely to the conveying direction of the prawns. As illustrated the edge (11) is set obliquely to the path of the prawns, and the feeler element (10) retains its orientation relative to its support arm (9) when the edge (11) contacts a correctly oriented prawn, but is caused to tilt about axis (12) when the edge (11) is brought to rest against an incorrectly oriented prawn or a foreign body, thereby moving a switching tag (15) past a sensor (13) which initiates rejection of the body by air from nozzle (7) of ejector (6). <IMAGE>

Patent GB-2216940-A (GB)
Title: Window installation
Inventor: HARRISON ALAN MALCOLM
IPC: E04F21/00
Filed: 1987-09-03
Abstract: Method and apparatus for installing windows which avoids the need for man-handling windows up ladders or up scaffolding or through window openings from the inside, all of which as well as being potentially hazardous requires more than one person except for the smallest of windows, especially when pre-glazed. We provide a winch (29; 112) carried by a frame member (11; 100, 102) which is positioned internally of the window opening into which the window is to be fitted. The winch is coupled by a lifting line (31; 141) to a lifting harness (37; 130, 150) adapted to carry the window. The lifting line is passed through the window opening. Accordingly, operation of the winch allows the window to be lifted into the window opening from a position externally of the opening and below it. Attaching the lifting harness to the window glass by suckers (134, 136, 154, 156) allows glazed frames to be lifted into position. Advantageously the lifting harness provides adjustable abutments (158, 160) for the lifting line to assist in aligning the window with the opening. A pivotable guide arm (180) extending from the window opening and with which the lifting line cooperates further assists lifting and window fitting.
