Title: Improvements in or relating to electrically controlled apparatus for performing functions at timed intervals
IPC: G03B15/08
Filed: 1931-11-21
Abstract: 385,716. Time switches ; control of motors ; photographic and kinematographic apparatus. KODAK, Ltd. and BUCKSTONE, W., Kodak House, Kingsway, London. Nov. 21, 1931, No. 32299. [Classes 38 (iii) and 38 (v).] A time switch G has a member G<2> adapted at a predetermined time to engage spring contacts H, H<1> to complete the circuit of a constant speed motor A provided with a centrifugal governor. The motor A drives, through a reduction gearing C, a shaft D carrying a coupling E for performing a desired function such as the operation of a kinematograph or photographic camera, including the operation of the shutter mechanism, illuminating apparatus and blinds for subjecting objects such as plants to daylight during the intervals between exposures. The shaft D also carries a conducting drum F having an insulating segment F<1> on which bear two brushes F<2> arranged in a circuit in parallel with the time switch G. The contacts H, H<1> are mounted on a rotatable part of the casing and so may be placed in any part of the path of the member G<1> to vary the time at which the switch shall operate. When this time arrives, the motor is started and a pin on a disc J<2> carried by the driven shaft D resets the member G<2> to zero. The motor circuit is, however, maintained by the brushes F<2> which are now on the conducting part of the drum F and the motor runs until the shaft D has made a complete revolution and the brushes rest on the insulating part F<2>. The operation is then repeated after a predetermined time.

Title: Improvements in coin-freed mechanism for automatic delivery machines
IPC: G07F11/24
Filed: 1934-11-09
Abstract: 428,917. Coin-freed article-delivery apparatus. HARPER, P. S., 1, Adelaide House, Ashurst Walk, Croydon. Nov. 9, 1934, No. 32332. [Class 27] Articles stored in piles.-Relates to a coin-freed article delivery apparatus of the kind described in Specification 336,818, [Class 27], wherein a pile of packets is supported by a rotary retaining device, which is moved by the weight of the pile, under control of a coin-freed escapement device, to deliver the bottom packet. According to the invention, the rotary packet-retaining device 3, Fig. 1, comprises a series of circumferentially spaced rods 7 disposed parallel to the axis of rotation of the device. The bottom packet of the pile 5 stored in a magazine 1 rests between a pair of adjacent rods as shown, one rod abutting against a vertical face of the packet and the other being located about half-way from the supported corner. The axis of rotation of the device is in line with one wall of the magazine 1. The rods 7 may connect together two end plates 6 or they may project a short distance inwardly from the plates 6, as shown in Fig. 4.

Title: Improved mechanical-overload electric switch
IPC: H01H35/00
Filed: 1960-09-20
Abstract: 963,990. Speed-responsive switches. MINNESOTA MINING & MANUFACTURING CO. Sept. 20, 1960 [Sept. 25. 1959], No. 32347/60. Heading H2B. A switch responsive to mechanical overload and suitable for use with a thermooopying machine such as that described in Specification 829,002, comprises a drum 10 mounted on a shaft 11 and engaging a friction-drive disc 13 fastened by rivets 26 to a first deflection plate 14, members 13, 14 having openings 22 which receive bolts 16 rotationally securing a second deflection plate 15 to the drum 10 and which allow limited relative rotational movement between members 10, 13. Springs 21 force tabs 24 on the plate 15 to engage tabs 23 on the plate 14, the tabs 23 forming an obtuse angle with the direction of rotation. A cover 17 is secured to a pest 18 on the plate 15 by a screw 19 whose head forms an operating member for a microswitch 20 and, if desired, a mechanical linkage. Normally the shaft 11, which may drive the belt of the thermocopying machine, is rotated by a drive cone 25 primarily through the engagement of tabs 23, 24, the friction between the members 10, 13 providing an additional driving torque. Should the load on the shaft 11 increase unduly, rotational movement between the members 10, 13 occurs which causes the tabs 23 to slide against tabs 24 and force the plate 15 away from the plate 14 to actuate the switch 20, which may open to extinguish the lamp supplying the copying radiation. The drive cone 25 may be replaced by a belt or multiplegear drive.

Abstract: 796,431. Drainage appliances. INGRAM, K. G. Nov. 12, 1956 [Nov. 14, 1955], No. 32501/55. Class 81 (2). A dental or medical suction tube comprises a tube having an opening in its wall intermediate its ends and a manually-operable cleaning member passing through the opening and capable of reaching a projecting from the end of the tube into which material is sucked. A passageway 3 is soldered or biased to a suction tube 1, the passageway 3 merging into the bore of the suction tube 1 near a nozzle 2. A clearing member 4 is slidable in the passageway 3 and can be projected into or beyond the nozzle 2 for clearing it. At its rear end the member 4 emerges from the passageway 3 and carries an adjustable block 7 which serves as an operating member and a stop for limiting the forward movement of the member. A guide 6 for the member 4 is integral with the rear end of the suction tube 1. The clearing member 4 is a sliding fit in the passageway 3 so that inward passage of air through the passageway 3 is negligible. The suction tube 1 may comprise a right-angle bend, the clearing member 4 being flexible and resilient.

Abstract: 1344178 Automatic exchange systems. SIEMENS AG 16 July 1971 [31 July 1970] 33408/71 Heading.H4K. In a four-wire telecommunication system including a plurality of centrally controlled exchanges interconnected for the transmission. of dialling characters by signalling only (data) links, at least one such exchange includes a four-wire folded switching network each fourwire inlet of which includes an arrangement controlled by the network control and by means of which the connections between the transmit and receive conductor pairs of an input and the corresponding conductors of an inlet of the A switching stage can be selectively reversed. The switching network may employ relays, crossbar or cross-coil switches. The two embodiments detailed employ relays. Connections between inlets can be set up over as few stages of the network as the spacing of the inlets to be connected allows. The transmit and receive pairs of each network input are connected directly and in cross-coupled fashion to the corresponding inlet of the A switching stage, via contacts sets one or other of which sets are closed. The contacts of the sets may be make and break contacts respectively of a single relay or the two sets may be controlled by separate relays. In either case the relays are latching relays which are set in one state or the other in accordance with a setting current and' remain in that state when no current exists. The relays remain in the state determined by their last use until required in the other state for a subsequent connection. The figure shows a single input E to the network connectable via direct and cross-coupling contacts 1k 2 to. 4k 2 and 1k 1 to 4k 1 respectively to crosspoint contacts lkr to 4kr of a single crosspoint of the A switching stage. Each of these three sets of contacts can be closed or opened by energizing one or other of two row-select wires e3 or e4 and a column-select wire p1, p2 or a3, the relative polarity of the potentials applied the enabled row and column select wires being in accordance with the state to which the relay is to be set.
