Title: Improvements in release mechanisms for coin chutes and the like
IPC: G07F1/04
Filed: 1980-01-21
Abstract: A coin chute release mechanism for use in the coin escrow (10) of a coin operated telephone instrument is provided with a coin stop (12) at which the leading coin (11A) of a accession of coins (11A, 11B...) in the escrow (10) is supported on a shutter (13). The shutter (13) is arranged to be laterally displaceable to expose a coin release opening (14) in the floor (10A) of the escrow. The coin supporting surface (13A) of the shutter is arranged to lie a distance below the floor (10A) of the escrow (10) to minimise the risk that the next coin following the last coin to be released from the escrow (10) will interrupt the return movement of the shutter (13). <IMAGE>
Patent GB-2068194-A (GB)
Title: Loudspeaker circuits
IPC: H04R3/04
Filed: 1980-01-22
Abstract: The invention consists of a filter to be connected in parallel with loudspeaker drive-units whose purpose is to minimise the impedance variation at the filter and drive-unit combination. This also modifies the electro-mechanical damping of the unit. The filter comprises two elements, one resistive and equal in value to the resistance of the drive- unit. In series with this there is a reactance whose value is determined by the relationship C = L/R<2> where L (or C) is the mean reactance of the drive unit and C (or L) is the corresponding value of the filter reactance. The values may be within the range {50% to +100% of those stated.

Patent GB-2069957-A (GB)
Title: Conveyor scraper
IPC: B65G45/14
Filed: 1980-02-22
Abstract: In order to remove adhering material from a conveyor belt J, a plurality of blades A are coupled to a rotary shaft D positioned so that the blades A wipe the belt J as the shaft D rotates. The blades A are disposed within respective outer casings C pivoted on pivot shafts B between two blade mounting flanges on the shaft D. The arrangement is such that the blades A are forced centrifugally outwardly as the shaft D rotates against a spring force provided by cushioning springs. This enables the blades A to wipe the belt J over a relatively long distance and to move back to clear an obstruction on the belt J, thus providing a particularly efficient wiping action.   <IMAGE>

Title: Apparatus for coating the outside surfaces of hollow bodies
IPC: B28B19/00
Filed: 1980-06-06
Abstract: The invention provides a mould for moulding a coating around a body, e.g. a concrete coating around a steel pipe. The mould comprises a base trough formed by elongate members (30) extending side by side between and resting on spaced supports (10) of channel section (11), and a top closure therefor comprising further elongate members (30) extending between and carried by arm members (20) pivoted to the supports (10) for pivoting of the closure between an open position for placing of a tube (0) in the trough and a closed position in which the trough and closure surround the tube (0).

Title: Procedure and apparatus for conveying external input and output data to a processor system
IPC: G06F13/12
Filed: 1981-06-11
Abstract: For conveying the input and output data of a process or of other computer-controlled apparatus or equipment to a processor system comprising one or several central units (4) with memories (5), the input and output data (I/O) are separated from the central units by means of I/O memories (3). The data transfer between the input and output data matching unit (2) and the I/O memories (3) is performed by an I/O copier (1). The copier is a processor which copies data from an input multiplexer to the input memory section of each central unit simultaneously, and copies output data from each central unit to the input/output memories of all the units. <IMAGE>
Patent GB-2103418-A (GB)
Title: Packaging of electronics components
Inventor: BRACEY STANLEY
IPC: H01L23/495
Filed: 1981-06-18
Abstract: A thin strip of aluminium, copper or other conductive material is punched etched or otherwise formed so as to produce a series of sets of leads, with each set held together at the extremities by an outer and an inner frame. Each set can be of a specific pattern, or of a general pattern, such that successive fabrication removes undesired portions of leads, leaving the resulting complex and specific shaped for the leads, which, after bonding, form integral connectors. (The bond may be of any suitable means dependent on the needs of the component under assembly). The semi conductor die electronic component is placed in position and bonded immediately following the removal of the inner frame of the leads. Subsequently, encapsulation in ceramic or plastic casing completes the packaging. The more substantial ends of the leads can be bent to form the connectors if required. If desired, the tape may be converted from a mono-layer system to a testable system with ease.

Title: Gaming machines
IPC: G07F17/32
Filed: 1982-04-01
Abstract: A fruit machine comprises a control system 1 which controls a reel mechanism 2 in dependence on depression of game/game-feature buttons 3. When a coin is introduced into the machine a certain predetermined proportion of the value of the coin is credited to each of a game accumulator 4, a hold accumulator 5, a hop accumulator 6, a nudge accumulator 7 and a jump accumulator 8. When a winning combination is obtained on the reel mechanism 2 as a result of a normal game, the value of the prize awarded is subtracted from the game accumulator 6, whereas, when a winning combination is obtained as a result of a hold, hop, nudge or jump game feature, the value of the prize is subtracted from the appropriate one of the accumulators 5 to 8. If the value in the game accumulator 4 becomes negative the control system 1 goes into a low pay-out mode, whereas, if the value in one of the accumulators 5 to 8 becomes negative, the corresponding game feature is not made available to the player. This ensures accurate control over the pay-out associated with the game and each of the game features and enables the various pay-outs to be separately adjusted. <IMAGE>
