Title: Arrangement for converting direct current into alternating current by means of electric vacuum valves
IPC: H02M7/51
Filed: 1929-10-24
Abstract: 330,861. Maschinenfabrik Oerlikon. Nov. 9, 1928, [Convention date]. Vapour and vacuum or lowpressure apparatus, arrangements of.-In an arrangement for converting D.C. to A.C. by means of electric vacuum valves in which the valves are rendered electrically conductive by alternating rhythmic ionization, condenser circuits in parallel with the valves are connected through the windings of a transformer so that the condenser discharge current at the moment of ionization of one valve induces a quenching current in the condenser circuit of the other valve. In the circuit shown in Fig. 1, assuming that, at a given moment, the valve V1 is conductive whilst the valve V2 is non-conductive, then the condenser C1 is short-circuited through the valve V1 whilst the condenser C2 is charged up to the potential of the anode A2. If now the valve V2 be energized through the ionizing anode Z2, the condenser C2 will discharge via the transformer T1 and valve V2 and the current induced in the circuit of condenser C1 will quench the valve V1. As the potential of the anode A1 rises the condenser C1 becomes charged and when valve V1 is rendered conductive the same cycle is repeated. The rhythmic ionizing of the valves V2 and VI is thus accompanied by a rhythmic quenching of the valves V1, V2. Fig. 2 shows a modification of the above circuit so that in the event of overload or short-circuit the valves are rendered non- conductive and the source of ionizing potential cut off. If the current from the source Q increases above a certain amount the switch Sch opens and removes the short across the part of the third winding of the transformer T1 so that the whole of the turns become effective and a voltage is induced in the two condenser circuits and the valve that is conducting at that moment is cut out. To cut off the ionizing supply the return lead 3 has in series a valve V3 across which is connected a circuit 03, R3 coupled by a transformer T11 to the positive lead from the source Q. Normally this valve is conductive, but when switch Sch opens due to overload the whole of primary winding of transformer T11 becomes effective and a potential is induced in the condenser circuit which quenches the valve V3.

Title: Improved method of and apparatus for affixing labels on non-circular cans and packages
IPC: B65C1/04
Filed: 1926-12-29
Abstract: 269,110. Cereghino, J. A. Dec. 29, 1926. Labelling.-A machine for labelling non-circular cans and packages comprises means for feeding cans &c. to chucks, rotatably mounted on an endless conveyer chain, pasting devices and a magazine for holding labels carried on opposite sides of the machine, and means for rotating the cans as they are carried along by the conveyer so that they contact with the pasting devices and the labels to affix the labels to the can bodies. The invention is shown applied to a machine for labelling oval cans. Chucks 13 are rotatably mounted on the flat links of an endless chain 12, each chuck 13 being formed with a toothed edge 15. The cans slide down a shoot 18 and are retained in position for feeding to the chucks by spring-controlled stop blocks 35. The chucks are held with their major axes longitudinally of the conveyer by guide rails 16, and engage the projecting ends of the cans in the shoot 18 to spread the blocks 35 and seat the cans on the chucks. The gear 15 on each chuck then meshes with a toothed rack 21 to rotate the chuck and the can. Pasting devices, each comprising a vertical shaft 22 formed with rings 23, and a disc 24 carried on a shaft 25 to dip into a paste pan 26 and contact with the rings 23, are positioned so that the paste, applied to the rings 23 by the discs 24, is spread by the rings 23 on the oval cans near the ends of the major axes, the label being pasted at its ends and in the middle. Each pan of the pasting device is vertically pivoted and forced towards the conveyer by a spring-pressed plunger 24, the rings 23 being thus pressed up to paste the cans. When the can has rotated so that the label is fully applied, a smoothing member 31, near the end of the rack 21, is adapted to press against the overlapped label ends to smooth out wrinkles, the chuck passing between inclined rails 32 which slope upwards to lift the can from the chuck and then downwards to deliver the can. Guide rails 16 hold the chucks from turning on the return journey. In a modified machine, not shown, for labelling cans with corners, each corner of the can may be pasted, and the first corner repasted to secure the overlapped end of the label.

Title: Data processing system

Filed: 1974-07-26
Abstract: 1480782 Data processing system SIEMENS AG 26 July 1974 [6 Aug 1973] 33081/74 Heading G4A In a data processing system in which data is transferred between a central unit and a number of peripheral devices over a block multiplex channel as described in Specification 1,480,781 where the channel unit is unable to distinguish between "channel end" and "device end" signals, the channel unit is arranged to treat the first "end" signal received from a peripheral as a "channel end" by disconnecting the appropriate peripheral from the channel and to treat a subsequent "end" signal as a "device end" reconnect request. The arrangement allows a channel unit intrinsically unable to distinguish between "channel" and "device" end signals, and thus unable to determine when a peripheral is operating off-line and when data transfers to and from other peripherals could be made over the channel, to operate in block multiplex fashion. When the first "end" signal is received from a peripheral connected to the channel it is treated as a "channel end" signal and a special "disconnect command" provided in the channel program is accessed. The channel is thus disconnected and any further "end" signals received in the presence of the disconnect command may safely be interpreted as "device end" reconnect requests. If several such "end" signals are received they are resolved on a priority basis and the selected request is serviced by obtaining, through the disconnect command, the next channel command in the program. Start requests are processed as in Specification 1,480,781 except that each channel program begins with a disconnect command so that when, in response to the start command, the appropriate peripheral emits a "device end" reconnect request it is correctly interpreted by the channel unit and the next channel command for the peripheral is accessed as above.
