Inventor: COOK DEREK MULVANEY
IPC: A63F9/14
Filed: 1960-12-07
Abstract: 922,250. Race games. CHAD VALLEY CO. Ltd. Dec. 7, 1961 [Dec. 7, 1960], No. 42053/60. Class 132 (2). In a race game in which the pieces are adapted to move along a base by vibration, the base is adapted to be vibrated perpendicularly of its plane. Such vibration is effected by a batteryoperated motor 23 mounted beneath the base 10 with its rotational axis parallel to the base 10 and its shaft carrying an eccentric weight 51 thereon. The speed of the motor may be varied by a stepped rheostat arranged in a mat form 23 below the board and controlled by a knob 33. The race pieces 37 comprise race horses and have bases 36 with nylon strips 38 protruding in a trailing direction therefrom.

Filed: 1973-09-06
Abstract: 1446037 Monitoring loud-speaker installations GENERAL SIGNAL CORP 6 Sept 1973 [6 Sept 1972] 42058/73 Heading H4J In an audio system, e.g. public address system a number of audio devices, e.g. loudspeakers 112, 114, 115, are connected in parallel across a line 101 at various remote locations, each device having a D.C. blocking element 113 in series and the remote end of the line being terminated by an impedance 103. A line supervisory sensor is connectable to the line and indicates, according to its state, the D.C. continuity of the line, an open circuit in the line, or a short circuit, or low impedance shunt across the conductors of the line. Preferably the sensor is connected to the line in place of the amplifier 119 output by operation of relay 120 and includes either a two step relay, Fig. 2 (not shown), having one pair of contacts operated at one predetermined current level, i.e. the normal current in the line, and further contacts operated by a current above a second higher predetermined level, i.e. when a low impedance shunt is across the line; or includes two relays in series, Fig. 3 (not shown), or in parallel, Fig. 4 (not shown), in series with the line and having different operating current thresholds, or includes a transistor circuit, Fig. 5. In Fig. 5, with normal current flow, transistor 503 will conduct due to current through diode 501 and resistor 502, very little current will flow through resistor 506 and transistor 507 will be cut-off. If the line is open circuited no current will flow through diode 501, transistor 503 will be cut off and transistor 507 turned on to operate the alarm. If the lines are short-circuited transistor 503 will conduct but greater current will pass through resistor 506 and viode 510 and again transistor 507 will conduct to operate the alarm.

Filed: 1960-12-09
Abstract: 945,156. Photographic cameras. INTERNATIONAL POLAROID CORPORATION. Dec. 9,1960, No. 42510/60. Heading G2A. In photographic apparatus wherein supports are provided for first and second strips and define for these strips respective first and second paths for the passage of the strips on longitudinal movement thereof, the first path extending past an exposure position for photographically exposing the first strip and also extending for part of its length in close proximity to the second path, drives are provided in the apparatus for the movement of the first strip in a first or forward direction along its path whilst the second strip is maintained stationary and for the movement of the first strip in the reverse or backward direction along its path and the movement of the second strip in the same direction at the closely adjacent parts of the paths. A camera embodying such an apparatus comprises, as shown, a lens-shutter assembly 24 and an exposure aperture 22 through which a film strip 30 is exposed in successive image areas, the film strip being fed from a spool 34 to a spool 62 by means of driven rollers 40 and 42 and by freely rotating guide rollers 86, 52, 50 and 64, a backing plate 44 being held by means 46 in the position shown in Fig. 1. During exposure, a window 60 in a second strip 32 remains in register with the aperture 22. When it is required to develop the latent images thus obtained, plate 44 is moved away from the strip 30, rollers 66 and 84 are moved upwards to lie adjacent rollers 64 and 82 respectively (Fig. 3, not shown), the feed means are reversed to drive strip 30 and thereby also strip 32 from left to right (Fig. 1), and liquid for affecting the diffusion transfer process is either squeezed or allowed to flow from a dispenser 72 through a valve 78 to form a film between the two strips. The print receiving strip 32 which was stored on a spool 36 may be fed between cutting knives 96 to an external spool 94. Various modifications are referred to. The dispenser 72 for example may be replaced by rupturable containers of known type on the strip 32. The strip 32 need not be provided with a window 60 (in which case it would be located on the side of strip 30 away from the exposure aperture 22). Other feed arrangements are possible such as independent feed means for the two strips, a single feed roller coupled to the spools through slipping clutches, and driven spools. The spools may be replaced by cassettes. The film strip comprises preferably, but not necessarily, a silver halide emulsion layer. The images may be developed in a layer of the strip 30 itself. Specification 684, 592 is referred to.

The gripper head 122 comprises support bodies 129 having clamps 130 and mounted on a piston 126 which is radially extensible by a ram 127. The head is rotatable about its own axis and displaceable along the axis of the ring. In use, the piston is raised through one of the cut-away portions in the carriage and the bodies 129 clamp and raise the section, a support block 128 being raised to engage the centre of the section by a further piston and cylinder unit 131. After the carriage has been driven back toward the conveyor, the piston is lowered until the section rests on forked support shoulders 123 and carrier blocks 124 which may be adjusted in level relative to one another. Clamps 125 on the shoulders 123 grip the section and the gripper head may be disengaged.

A recess is mechanically cut in a semiconductor body to extend through a layer of one conductivity type extending over the entire surface of a body of different conductivity or conductivity type, and then etched. At least 80% by volume of the material to be removed is removed in the mechanical cutting, the etching preferably removing only material damaged in this process. To this end where the body is silicon a specified mixture of nitric and hydrofluoric acids with a modifier chosen from acetic acid and sodium and potassium hydroxides is used. In the embodiment, Fig. 4 (not shown), a PNPN controlled rectifier is formed by cutting an annular recess through an aluminium diffused N-type layer on a high resistivity P- type silicon body using a hollow emery- or diamond-faced cylinder, followed by etching. A circular PN junction and surrounding annular control contact are formed in the circular N layer thus isolated by alloying in gold-boron and gold-antimony foils respectively. Alternatively the alloying may be effected before the recess is formed.
