Abstract: 257,817. Gandz, S., and Goss, C. E. Feb. 2, 1926. Table games.-In apparatus for playing a table game of skill of the kind wherein the surface of the table is divided into squares into which the players endeavour to throw discs, some or all of the squares are provided with electrical contacts insulated from each other and situated so to be bridged by a metal disc if resting wholly within the square but not otherwise, and an indicator is provided in circuit with the contacts for indicating the presence of a disc wholly within the square. In one form, the surface of a round table a, Fig. 2, is divided into sectors and each sector is divided into squares. The centre of the table is occupied by an octagonal pyramid b carrying indicators f and bells h. Some of the squares are provided with insulated contact wires d, e, Fig. 3, arranged in circuit with the indicators f and bells h. When a metal disc k rests within the square the contacts are bridged and one of a number of lights behind the corresponding indicator f is illuminated to show the value of the square, and at the same time the corresponding bell is sounded.

Title: Improvements in and relating to control circuits for single phase capacitor motors
IPC: H02P1/44
Filed: 1945-02-06
Abstract: 621,470. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 6. 1945, No. 2962. Convention date, Feb. 8, 1944. [Class 38(iii)] A control circuit for producing normal running, reversal or dynamo-electric braking, of a capacitator motor of the type having a speed controlled switch engaging starting or running contacts, includes a relay connected to the starting contact and also, when energized, in series with the main winding across the supply. With the controlling switch in the starting position 1, current flows from lines 16, 17 via contact 22 through starting winding 12 and the centrifugal switch 14 on contact 32 to energize the relay 15 to engage contact 29 thus feeding the main winding 11 through reversing contacts 23, 24, the relay being held in by the motor current. At a pre-set speed, the centrifugal switch 14 moves over to contact 31 and the starting winding is de-energized. If the switch is put into position 2, the main supply is cut off at contact 22 but the longer bladed contacts 23. 24 remain connected. Operation (on de-energization) of relay 15 into the position shown connects the two windings and the condenser 13 in series which effects braking down to the speed at which the switch 14 moves to contact 32. The machine may now either be " plugged" and run in the opposite direction by putting the control switch in position 5 or allowed to stop normally. Position 3 (shown) disconnects the machine and allows it to slow down naturally from top speed. Self-energized braking is obtainable in either direction of rotation in either position 2 or 4 and in a modification, Fig. 3 (not shown), only one of the pairs of reversing contacts is elongated for this purpose. This modification also incorporates a rearrangement of the circuit in which there is no running contact on the switch 14 so that braking is not dependent on .the position of this switch. In a further modification, Fig. 2 (also not shown), all the contacts are of the same length and quick reversal of the control switch produces braking, plugging and reversal of rotation as before, but to obtain only braking it is necessary to open the switch to de-energize the relay, and then to close it again until the centrifugal switch moves over to the starting contact.

IPC: B21F99/00
Filed: 1949-02-09
Abstract: 660,228. Shearing; trimming. LUCAS, Ltd., J. Feb. 1, 1950 [Feb. 9, 1949], No. 3525/49. Class 83 (iv). [Also in Group XXIV] A shearing-machine for trimming the ends of wires after winding an electric armature, or for trimming ends of drawn or pressed metal articles and like operations comprises a bed a, supporting a stationary shearing- tool b, a member e of rectangular form carrying an annular shearing tool g surrounding the tool b, two pairs of slides d arranged at rightangles to each other and on which member e is supported, and a rotary cam h adapted to reciprocate the slides. The tool b has a central recess q which receives one end of the spindle of the armature p, the other end of the spindle being received in a, recess w<SP>1</SP> in a hinged cover w. The cam h is toothed on its outer surface and rotated by a pinion m, driven by a motor x through a clutch z and gears 10. During its rotation the inner surface of the cam causes first one pair of opposite slides d to reciprocate and move the tool g beneath opposite cutting edges b4 of the tool b in turn, to sever the adjacent wires, the other pair of slides remaining stationary and guiding the member e, and then the second pair of slides to reciprocate and shear while the first pair remain stationary. A spring-loaded lever 12 holds the clutch members 2 and 3 out of engagement, when the cover w is raised and the operation is initiated by the closing of the cover, which causes a peg 15 on the lever 12 to move out of engagement with the clutch and allow its members to engage, the lever 12 simultaneously moving a stop-rod 32 out of a recess 34 in the cam h, allowing the cam to be rotated by the pinion m. Opening of the cover w is prevented during the ensuing revolution of the cam, by the engagement of a projection 22 on a lever 18 with a-shoulder 28 on a segment 26, completion of the revolution of the cam then allowing the stop-rod to enter the recess 34 and the lever 12 to return to its initial clutchdisengaging position under the action of its spring 14, and the lever 18 to move its projection 22 out of the path of the shoulder 28, enabling the cover to be opened. A cover-piece i surrounding the tool b may be shaped as at s, Fig. 1, to allow wires which it is not desired to shear, to be splayed out and held away from the shearing edges.

Title: Improvements in protective switch gear systems for polyphase electric power transmission and distributing networks
IPC: H02B1/24
Filed: 1956-02-03
Abstract: 820,711. Protective cut-out arrangements. ELECTRICITE DE FRANCE, SERVICE NATIONAL. Feb. 3, 1956 [Feb. 3, 1955], No. 3535/56. Class 38 (5). A polyphase protective system comprises a circuit-breaker connected between a bus-bar set and earth, the several phases of the circuitbreaker being individually controlled by respective fault-responsive means in the several phases of the protected circuit whereby a fault to earth in one or more phases or a fault between phases causes the contacts of the corresponding phase or phases of the circuit-breaker to operate, thereby short-circuiting the fault path and permitting disconnection of the faulty phase by an isolating switch. As shown in Fig. 4, a 3-phase bus-bar J supplies feeders L 1 , L 2 , L 3  through isolating switches SRS 1  &c., the circuit-breaker I being normally closed and connected to the bus-bar J through a normally open isolating switch SR, the other side of the breaker I being connected to earth through a bus-bar Jm and normally closed isolating switch ST. Normally open isolating switches SRD 1  &c. may connect the feeders L &c. to earth through the switch ST. Relays 1, 2, 3 controlled by potential transformers Tp and current transformers Ti 1  &c. operate the respective phases of the breaker I and isolating switches in response to abnormal conditions in the feeders. On occurrence of a transient earth fault the respective relay of the faulty phase of that feeder causes closure of the corresponding phase of switch SR, followed immediately by opening of the corresponding phase of breaker I, the switch SR consequently opening and breaker I closing. In the event of a permanent earth fault the following additional operations occur: switch SR closes, the respective switch SRD of the faulty feeder closes to earth that feeder through switch ST, the switch SRS of the faulty feeder opens, the breaker I opens, the switch SR opens, and breaker I closes, the feeder thus remaining earthed. For normal control operation a feeder L is switched in by closure of its respective switch SRS. To open a feeder L, switch ST is opened, SR is closed, the corresponding switch SRD is closed, and SRS can now be opened with zero volts across its terminals. The breaker I is opened, switch SRD is opened and switch SR opened. Breaker I and switch ST are then closed. Fig. 5 (not shown) shows a pair of 3-phase busbar stations supplying a pair of 3-phase feeders, either one of which may be connected to either station, the whole system being protected and controlled by a pair of circuit-breakers and a number of isolating switches as described with reference to Fig. 4.
