Abstract: 1,185,589. 'Bingo' type game. R. J. WILLIAMS. 25 Nov., 1968, No. 55902/68. Heading A6H. [Also in Division G3] A game comprises a plurality of differently numbered cards of the 'Bingo' type, e.g. Fig. 1 where the highest number appearing on any card is 66, a pair of dice and a clock. In play, each player in turn throws two dice together to determine which members may be cancelled on his card, of which he has at least one, the two digits on the dice being counted in specified ways; added, subtracted multiplied, read in tens and units in either direction, counted as any number beginning with a digit if the other digit is a six, are counted as any number if both digits are sixes, points being scored by the player for each number cancelled. The game may have certain specific objectives; cancel middle row or column only, cancel diagonal rows, cancel top and bottom rows, cancel full card; there being extra points awarded to the first player to complete each objective, the overall winner being the player who has scored most points. For further specified ways of counting the digits spaced by throwing the dice; squaring the sum or the difference of the digits, adding or subtracting the square of the digits; may be used only when certain portions of each specified objective are completed. On completion of each game the cards are passed from one player to the next for the next game. If a player does not make a cancellation within a certain time he may not do so thereafter. The time is judged by a battery driven clock, which is started by pressing switch 7, Fig. 9, which completes a circuit, including batteries 12 and solenoid contacts 19 to drive motor 10 and electromagnet 15, which controls a clutch thus rotating the hand of the clock at one rev per minute. Cam operated contacts 17 are immediately closed, and the switch may be released. The clock automatically stops when the hand touches a wander plug which may be attached at any 5 sec mark on the clock face, this closing contact 6, energising solenoid 18 which breaks contacts 19, makes contacts 20, stops motor 10 and releases the clutch via electromagnet 15. The hand sways under force of gravity to zero time, contact 16 immediately being broken. At zero time on the clock face cam operated contact 17 is broken, and contact 19 is re-made, the clock thus being ready for further use.

Title: Circuit arangement for the forced switching-off of thyristors
Inventor: HUBER ERICH
IPC: H02M1/06
Filed: 1968-12-11
Abstract: 1,213,210. Control of D.C. motors. SCHALTBAU G.m.b.H. 11 Dec., 1968 [13 Dec., 1967], No. 58823/68. Heading H2J. [Also in Division H3] A main thyristor 3 in a motor control circuit is switched off by an extinguishing thyristor 4 discharging a capacitor 5, whose charge is previously reversed by a reversing thyristor 6; and inductances 9, 6 in series with each of the extinguishing and reversing thyristors 4, 7 are arranged in the magnetic field of an inductance 8 in the main thyristor path whereby the switching action of the thyristors 4, 7 is enhanced. When the current source 1 is connected to the main thyristor 3 a pulse train is simultaneously applied to extinguishing thyristor 4 to turn it on so that the capacitor 5 is charged from the source 1. When main thyristor 3 is turned on, the reversing thyristor 6 is also turned on, and the charge on the capacitor 5 is reversed. When main thyristor 3 is to be turned off, the extinguishing thyristor 4 conducts the charge on the capacitor 5 to the cathode of the main thyristor 3 to reduce its current sufficiently to turn it off. The rising magnetic field of the inductance 8 during initial conduction of the main thyristor 3 causes the inductance 6 to boost the charge-reversing current flowing at that time through it; the capacitor finally has a voltage greater than that of the source 1. The collapsing magnetic field of inductance 8 during turn-off of the main thyristor 3, produces a boosted current in the inductance 9 which assists the extinguishing of thyristor 3. In modifications, a transformer (10, Fig. 2a, not shown) responds through a Zener diode 11 to the fall in voltage across the main thyristor 3 during initial conduction thereof and provides an increased charging voltage to the capacitor 5. Alternatively, a transformer (12, Fig. 2b, not shown) responds to the gate signal applied to thyristor 3, to apply an already reversed voltage directly to the capacitor 5 to increase the stored charge, thereby restoring energy in the capacitor 5 if the main thyristor 3 is maintained conductive for such a period that the capacitor 5 is prematurely discharged.

The rollers are driven by a motor 11 via belts 21c, 23b (Fig. 4) which bear on recessed portions 26 of the rollers 9. The diameter of the portions 26 progressively varies from roller to roller so as to provide successively increasing or decreasing roller speeds. The carriage members 3, 4, have outwardly spring-urged rollers (36) (Figs. 7-10, not shown). The members 2 may be pivotally connected to the members 1 (Fig. 11, not shown). The conveyer may turn in a horizontal plane (Fig. 2, not shown), or may pass around a return path curving downwards (Fig. la, not shown). In an alternative construction (Fig. 12) the members 1 are driven by the reaction between a driven roller 48 and a disc 47 mounted on the member 1. Speed of the member 1 is varied by altering the direction of the pivotal axis of the disc 47. This is determined by the profile of a cam 52 on the conveyer framework, and a cam follower connected by linkage to the disc 47. In a modification (Fig. 13, not shown), the roller 48 may be mounted on the outside of the conveyer frame. Also, the upper carriage member 3 may be replaced by a member (53) which bears on a rail (54) mounted between the conveyer side frames.
