Title: Sound reproducing devices
Inventor: KOIKE EISHI
IPC: G11B25/04
Filed: 1982-11-08
Abstract: A simple sound reproducing device, comprises a turntable (3) is coupled to a governor by a belt drive (8), and the angle of the V-groove of the governor pulley is defined to be at least 60 DEG  and not more than 90 DEG , the resilient belt 8 having a round cross- section. One or more brake members 6 are each normally urged by an associated spring 10 to move away from engagement with the inner face of a cylindrical chamber (4) formed in the casing. By virtue of this construction, the control function of the governor has been rendered exact, and slippage of the belt between the turn-table and the governor avoided when the device is incorporated into toys which may be used in dry conditions, in wet conditions, or actually in water. This construction allows use of a heavier brake member, which is necessary to avoid insufficient frictional engagement of a brake member with the inner face of the cylindrical chamber due to resistance given by water being present in the chamber between the brake member and the chamber wall. <IMAGE>

Patent GB-2117355-A (GB)
Title: Tape dispensing pack
Inventor: HEARD ROBERT ARTHUR HENDERSON
IPC: B65H75/16
Filed: 1983-02-28
Abstract: A coil of steel banding tape (30) is contained within a flat container. The end of the tape is withdrawn from an aperture (20) in the outer peripheral wall of the container, and the central space (34) in the container is large enough to admit the human arm, so that the pack can be carried on site on the arm of the user. The flat annular walls (14, 24) may be slightly convex in profile between the inner and outer peripheral walls so that the coil is not clamped by the user gripping the pack in one hand during dispensing of the tape. The inside surface of the outer peripheral wall is preferably also provided with a series of inward projections (22) to keep the tape out of contact with the inside surface of the wall. The inner and outer peripheral walls (26, 28) may be circular or rectangular. The container is made of two mouldings secured together by adhesive or welding, each moulding having an annular wall and inner and outer peripheral walls such that the peripheral wall of one moulding fits radially inside and in contact with the corresponding peripheral wall of the other moulding. The extent of interfitting of the mouldings depends on the width of the tape. <IMAGE>

Patent GB-2127508-A (GB)
Title: A brake pressure regulator for an hydraulic vehicle braking system
Inventor: WLOCZYK UWE WILHELM
IPC: B60T8/26
Filed: 1983-09-19
Abstract: In a housing (10), a stepped piston (40) bounds an inlet chamber (20) with its smaller face (A36) and an outlet chamber (24) with its larger face (A38). These two chambers (20, 24) are connected to each other by a valve (44, 46) which is controlled by the stepped piston (40). The inlet chamber (20) is also bounded by an auxiliary piston (30). Between the two pistons (30, 40), a spring (54) is arranged which tends to hold the stepped piston (40) at a first stop (52) against the pressure in the outlet chamber (24) and to hold the auxiliary piston (30) at a second stop (56) against the pressure in the inlet chamber (20). The difference between the faces (A38-A36) of the stepped piston (40) is greater than the operative face (A30-A36) of the auxiliary piston (30) on the inlet side. Movement of the auxiliary piston (30) in the direction of the outlet chamber (24) is limited by a third stop (58) formed on the housing (10), said stop not interfering with the freedom of movement of the stepped piston (40). The brake pressure regulator, which is preferably connected in series to one or more rear-wheel brakes, thus takes on a regulating characteristic which closely conforms to the ideal, almost parabolic curve of pressure in the rear- wheel brakes in relation to the pressure in the front-wheel brakes. <IMAGE>

Title: Optoelectronic coin entry sensing system for coin operated machines
Inventor: HAGIWARA TAKASHI
IPC: G07D11/00
Filed: 1983-12-23
Abstract: For sensing the proper entry of a coin into a slot machine, a chute 10 extending from the slot has two pairs of apertures 14 and 16 formed therein. A coin falling through the chute successively intercepts light beams from light sources 18 and normally falling on photodetectors 22 through the apertures. The outputs from the photodetectors are used for measuring the time required for the coin to pass each pair of apertures and the time from the moment the coin starts passing the upper apertures to the moment the coin completes passing the lower apertures, and are further utilized for detecting a reverse travel of the coin, as by the stringing of the coin by the customer. Logic elements 26-32 direct clock pulses to counters 40-44 in response to the photodetector outputs and the final counts are compared with reference values by sensing circuit 46. Additional embodiments detect oversize and undersize coins. <IMAGE>

Title: Infra-red fresnel lenses and methods of fabrication
Inventor: PEDDER DAVID JOHN
IPC: G02B3/08
Filed: 1985-07-04
Abstract: In the prior art, infra-red lenses have been fabricated from germanium and zinc selenide, and these have shown to possess useful optical characteristics whilst also being robust. However, the commercial cost of design and fabrication of such lenses is considerable. To reduce the design and fabrication costs, Fresnel-type lenses of certain polymer materials have been made. Such lenses generally have unacceptable optical characteristics and lack thermal and mechanical stability. To overcome these problems, an infra-red lens having a Fresnel-type structure fabricated from an infra-red transparent elemental or compound semiconductor material such as silicon is proposed. A method of fabrication of such lens includes a step of impressing a desired lens structure into the surface of a wafer of the infra-red transparent material by means of a light controlled etching technique.
