Title: Gaming machine
Inventor: TRACY DANIEL ALAN
IPC: G07F17/32
Filed: 1988-10-11
Abstract: A poker machine or slot machine in which the symbols or indicia to be displayed are selected by using a random number generator to generate a random number for each display position, the random number being selected from a range corresponding to the number of display possibilites for that position. The random numbers are then compared with one of two look-up tables A & B to select the actual symbol or indicia to be displayed. Each of the two look-up tables has a different symbol sequence and gives the player a different probability of winning than the other, one being greater than and the other being less than the target return for the machine, and the machine monitors the overall rate of return to players and switches between the two look-up tables in order to maintain the overall rate of return within tolerable limits around the target return for the machine. <IMAGE>

Title: Differentially cooled mould for foam injection
Inventor: HAFTMANN JOHANNES
IPC: B29K105/04
Filed: 1989-01-20
Abstract: The invention relates to a method of producing platens for imprinting machines. Such as typewriters from an impact- resistant polyolefin, with the addition of a delayed action blowing agent, by injection-moulding. Different regions of the mould are cooled differentially so that the plastics material sets solid in the region of the surface of the platen proper and in the region of additional structural elements such as line-space ratchet and detent wheel combinations, while the core of the platen proper is foamed in the region of the actual printing support. 
<??>The method allows platens, combined with further structural elements, to be produced from one material, in a single operation, despite the different requirements for different parts of the platen, and finishing operation are unnecessary.

Title: Electromechanical transducer
Inventor: FORD LESLIE HOWARD
IPC: G10K9/12
Filed: 1989-04-29
Abstract: An underwater acoustic pulse projector 20 comprising a planar coil 23 and plate-like copper piston 21 configuration overcomes problems associated with known constructions (Fig. 1 not shown), in which the coil is embedded in a thick epoxy housing to withstand reaction forces from electromagnetically displacing the piston whilst providing electrical insulation for underwater operation, due to poor heat transfer through the epoxy housing when the coil is energised at a high duty rate. The coil 23 is sheathed in a thin layer of GRP resin 24 which provides adequate electrical insulation and heat flow but not structural strength and this coil assembly 22 is mounted against a GRP reinforcing member 32 having apertures 37 and the housing 27, supporting coil assembly and reinforcing member, is open at 38 to the underwater environment which acts as a heat transfer fluid to remove heat from the surface of the coil assembly by way of the reinforcing member apertures. The opening 38 may be covered to protect the coil from damage and possibly not apertured, permitting a different heat transfer fluid. <IMAGE>

Title: Automotive reflection type display apparatus
Inventor: AOKI KUNIMITSU
IPC: G09F9/00
Filed: 1991-02-07
Abstract: A prism reflector (2) installed immediately above an indicator display surface (1a) consists of a prism (21) and a flange portion (22) that is flush with one surface (21 A) of the prism and which extends from the periphery of that surface. The surfaces of the prism and the flange portion form a reflecting surface (2A). A reflector plate (3) is arranged to face the reflecting surface of the prism reflector and has a concave surface, whose light axis (L) is inclined with respect to the reflecting surface of the prism reflector toward the thicker side of the prism. Light from the indicator's display enters the prism, is refracted as it leaves the reflecting surface (2A), and travels toward the reflector plate's concave surface, which reflects the incident light back toward the reflecting surface of the prism reflector, which then reflects it toward the driver's viewing point. <IMAGE>

Patent GB-2271875-A (GB)
Title: Coin validator
Inventor: CHURCHMAN JAMES
IPC: G07D5/08
Filed: 1992-10-14
Abstract: In a coin validation system a coin 1 passes between conductive plates 7, 9 which form a capacitor, which provides part of the frequency controlling capacitance of an LC tuned oscillator circuit 23. The presence of a coin 1 between the conductive plates 7, 9 alters the capacitance, and consequently the output frequency of the circuit 23. The oscillator output is supplied via a frequency divider 27 counter 31 and shift register 33 to a microprocessor 35 which subtracts the count value from a pre-stored reference value, and supplies the difference to a look-up table stored in a memory 37. The output of the look-up table 47 determines whether a coin is valid, and if so, what its denomination is. Preferably, while no coin is present the microprocessor 39 monitors the count values obtained from the counter 31, and updates the stored reference value so that it tracks drift in the frequency of the oscillator 23. The validator may also include optical sensors determining coin diameter. <IMAGE>
