Title: Apparatus for playing games of chance
IPC: A63F9/00
Filed: 1934-11-13
Abstract: 447,407. Games of chance. BESWICK, N. S., 7, The Avenue, and LITTLE, J. J., Rossett Green, The Avenue, Hipperholme, near Halifax. Nov. 13, 1934, No. 32624. [Class 132 (ii)] Chance apparatus comprises a casing a with aperture f and an endless band d rotated over rollers band c by a knob. The surface of the band d is marked with squares, some of which are coloured or otherwise distinguished from blank ones. A plate g also marked with squares registering over the squares on the band below can be slid by knobs working in slots h against the action of the spring i to a position beneath the aperture f and there retained by the catch k. Coins, tokens or the like can be positioned in a selected square on the plate g and on release of the catch k the plate g is quickly moved rearwardly by the spring j for the coins &c. to fall vertically on the band d in positions indicating the odds to be received or loss of the coin &c. The odds are given against the chance of the coin falling on a coloured square by the proportion of blanks to coloured in the row of squares in which the coil falls. The squares may be marked with fortunes, quotations, &c.

Title: Direction indicating apparatus
IPC: G06V30/144
Filed: 1964-08-11
Abstract: 1,008,059. Automatic character reader. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1964 [Aug. 29, 1963], No. 32656/64. Heading G4R. In a character reader of the kind in which the scanner follows the outline of the character and produces corresponding X and Y signals, these signals are differentiated to obtain signals indicating the speed of the scanning centre in the horizontal and vertical directions, these signals being compared to indicate the ratio of the two speeds by energizing one or more of a number of leads, the leads being connected to gates each representing a different range of direction of the scan movement. The X and Y signals are treated similarly as shown in Fig. 1. Only the circuit of the X signals will be described. Differentiation at 501 produces the speed or X signal which passes to a full-wave rectifier 504 and to a sign detector. The rectifier produces an amplitude signal representing the size of the input signal and the detector 502 produces an output on lead 510 if, X is positive (i.e. moving to the left or " westerly "). If X is negative inverter 503 produces a signal on lead 511. Divider 505 produces an output equal to 414 of the input X and also a signal equal to the input. In comparators 506, 508 X is compared with 414 Y and Y is compared with 414X. If the angle of the direction is less than 22¢ degrees, the direction is considered to be east or west according to the sign of X. If it is greater than 22¢ degrees but less than 67¢ degrees it is taken to be NE, NW, SE or SW depending on the signs of X and Y. If the angle is greater than 67¢- degrees the angle is taken to be north or south according to the sign of Y. The tangent of 22¢ degrees is 414 so that if comparator 507 gives a signal on line 516 indicating that X>À414Y the direction is outside the north and south zones, Fig. 5. It can be E, NE, NW, W, SW or SE. If the opposite is true, i.e. À414Y>X the direction is N or S. The actual quadrant in which the direction lies is given by the sign relationship. For example, if both X and Y are positive the direction is in the first quadrant, i.e. between west and north. The comparator outputs and their inversions are gated in gates 520-527 with the sign signals and the direction is indicated by an output on one of the leads 520a-527a. In another embodiment the four quadrants are treated as four overlapping semi-circles: semi-circle A counter-clockwise from a to a<SP>1</SP>, Fig. 5, semicircle B from b-b<SP>1</SP> and so on. A northerly direction is one which falls in semi-circle A but not in semi-circle B. North is therefore given by AB. Similarly other directions are given by NW = BC, W=CD, SW=AD. The opposites are given by the corresponding logical opposites:-S=AB, SE= BC,E=CD and NE= AD. The signals A-D are again obtained by comparing X with 414Y and so on and the resulting signals and their inverses are gated together according to the above relations to obtain direction signals.

Title: Improvements in or relating to devices for controlling the speed of, and/or for smoothing, the movement of objects
IPC: G21K1/02
Filed: 1948-12-17
Abstract: 644,459. Dashpots. GENERAL ELECTRIC CO., Ltd., and BRYER, R. F. Dec. 18, 1947, No. 33445. [Class 108(iii)] [Also in Group XX] A device for controlling the speed of movement and/or for smoothing the movement of one or more members, comprises, in combination, a piston head arranged to sweep out a portion at least of a cylinder containing fluid, connecting means joining one or more ports at each end of the cylinder so that movement of the piston head displaces fluid from one side of the head to the other and means for at least partially blocking the port or ports at either or both ends of the cylinder to decelerate the piston head when the latter is near the limit of its movement in one or both directions, the arrangement being such that the piston head is adapted to allow substantial flow of fluid through itself when the head is moving away from one end of the cylinder while the port or ports at that end is or are partially blocked. In the arrangement shown, a piston 2 which moves to displace oil in a cylinder 1 from one side of the piston to the other, through ports 6, 7 and a pipe 8, comprises a cylinder 9 having an internal flange 10 and spaced flanges 12, 13 of a collar 11 which is carried by a piston rod 3. The flange 12 is normally held in contact with the flange 10 by a spring 14. A disc 15 is slidable on the rod 3 and is spaced from the flange 13 by a spring 16. In operation, outward movement of the rod 3 is decelerated when the disc 15 contacts the end wall 4 of the cylinder 1 and restricts the flow of oil through the port 6. Further outward movement of the rod 3, which is limited by a projection 17 thereon, is effected against the compression of the spring 16. Subsequent inward movement of the rod 3 lifts the flange 12 against the spring 14 to permit oil to flow into the space between the cylinder 9 and disc 15. A second disc, cooperating with the port 7, may be provided to effect a deceleration of the rod 3 at the end of a movement in either direction. Flow of oil through the pipe 8 may be controlled by a rotatable apertured cylinder 18. In a modification, the ports 6 7 may be restricted by the piston itself. The device may be used in conjunction with a " Bucky diaphragm of radiographic exposure apparatus, (see Group XX), or other electro-medical apparatus.
