Abstract: 818,465. Statistical record cards. DIRKS, G. July 16, 1957 [April 25, 1956], No. 12613/56. Class 106 (1). A ledger sheet 2 for use in book-keeping operations is enclosed in an envelope-like container 1 having a magnetic recording area 5, the ledger sheet being removably held in the container and having one or more projections 3, 4 extending from the container to facilitate its mechanical withdrawal for recording information thereon. The front of the container consists of a sheet of transparent plastic or is cut away so that entries on the ledger sheet can be seen. The ledger sheet number is printed at 6 and 7 on both the container and the sheet itself. When it is necessary to make a recording on the ledger sheet it is partly withdrawn as shown in Fig. 2, the container being inverted on to abutments 8 so that the projections 3, 4 are gripped by rollers 13, 14. In, this position the data recorded in the magnetic strip 5 is read by heads 9 and 10 which are displaced horizontally to read the old balance and later moved back across the strip again to record the new balance. The head 9 may generate clock pulses during this movement as described in Specification 818,235.

Title: Improvements in arrangements for preventing false switching operations with lines provided with electric short-circuit protective devices
IPC: H02H7/26
Filed: 1944-07-06
Abstract: 576,998. Protective cut-out systems. AKT.- GES. BROWN, BOVERI, & CIE. July 6, 1944, No. 12939. Convention date, July 7, 1943. [Class 38 (v)] In a line provided at each end with reclosing circuit-breakers, which are adapted to be tripped under control both of H.F. currents transmitted over the line from the remote end, and of protective relays at their own end, undesired permanent disconnection by transient disturbances is prevented by arranging for the H.F. currents to perform only the disconnection followed by re-connection, final disconnection being left to the protective relays, which are preferably of the distance type. Circuitbreakers 2a, 2b are provided with switch coils 4a, 4b for interrupting a line 1 and reclosing it, and with switch coils 5a, 5b for final disconnection. If a distance relay 3a operates due to a short-circuit, the coils 4a, 4b are immediately energized, the former by relay 3a, the latter by H.F. signals transmitted from 6a to receiver 7b. Change-over switches 8a, 8b are operated by the coils 4a, 4b with time delay, so that final opening of the breakers 2a, 2b due to a fault can only occur by operation of the distance relays 3a, 3b. Disturbances on a sound line due to over-voltages merely produce operation of the coil 4a or 4b and temporary disconnection.

Title: Improvements in or relating to pressure responsive valves
Inventor: DENNY DOUGLAS FRANK
IPC: F15B1/027
Filed: 1960-04-12
Abstract: 965, 656. Fluid-pressure servomotor control systems. PRATT PRECISION HYDRAULICS. March 24, 1961 [April 12, 1960], No. 13012/60. Heading G3P. In a pressure responsive valve for use in a pressure system 36, 38 connected via check valve 37 to a pressure source, e.g. a pump 35, rising pump pressure acting via restriction 31 in chamber 15 keeps main spool valve 4 closed as shown with its end 23 connected to drain at 11 via auxiliary spool valve 5. As the system pressure increases via 39, 12, valve 5 is shifted against spring 21 to close drain 11 and allow system pressure to act at 23 and balance valve 4 which is held closed by a light loading spring 16. When the pump pressure opens the adjustably spring loaded relief valve 34, a pressure fall downstream of restriction 31 at 25, 10, 15 unbalances valve 4 which moves against spring 16 and connects the pump to drain via 25, 10, 11. When the system pressure has fallen to the setting of adjustment 22 of spring 21, spool 5 closes, disconnects spool 4 from system pressure and connects it to drain at 11 whereby spool 4 is balanced since its spring end has also been connected to drain, so that spool 4 closes under its spring 16 and the pump again operates on load. Relief spool 32 controlled by pilot valve 34 is well known and takes no essential part in the apparatus, but the valve 34 allows the cut-out pressure of the pump to be independently adjusted, while adjustment 22 allows the cut-in pressure to be independently adjusted. Line 25 may be dispensed with and relief valve 34 and restriction 31 incorporated in the main and auxiliary spool housing (Fig. 3 not shown).

Title: Means for regulating vapour arc converters and the like
IPC: H02M7/15
Filed: 1937-05-07
Abstract: 498,739. Converting. GENERAL ELECTRIC CO., Ltd. and DUNHAM, C. R. May 7, 1937, No. 13141. [Glass 38 (ii)] Load sharing between two converting arrangements employing grid controlled discharge devices, which may also operate in parallel with one or more rotary converters, is effected by including in the grid circuit of each converter a voltage proportional to the output current of the converter to reduce the output current with increase of load and a voltage proportional to the total load which acts in opposition to the first voltage. In the form shown in Fig. 1 a pair of discharge devices 2, 3 operate as rectifiers in parallel with a rotary converter 1. Load distribution is effected by grid control of the discharge devices. Each grid circuit includes a source of periodic control potential 9, a source 11 giving a D.C. bias proportional to the rectifier load current, and a source 14 giving a D.C. bias proportional to the total load current. By this means each rectifier circuit is controlled to give approximately constant current, with an overriding control dependent on the total load. In a system in which certain of the discharge devices are switched out at low loads the voltage from the source 14 is adjusted to effect compensation. If the rotary converter is not used, voltage sources 16, 19 are included in the grid circuits to modify the operating characteristics of the discharge devices. In a modification shown in Fig. 2, to provide a control such that the rotary converter takes the whole load up to its maximum, the grid circuit includes a voltage source 13a giving a bias proportional to the total load of the discharge devices, a voltage source 23 giving a bias proportional to the load taken by the rotary converter, and an opposing bias from across the resistances 24 proportional to the maximum load taken by the rotary converter. By this means the discharge devices are maintained at a minimum load until the voltage across 23 equals that across the resistance 24. Specification 496,811 is referred to.

Abstract: 497,258. Can - openers. LEACHMAN, E. C. May 10, 1937, Nos. 13252 and 15943. [Class 66] A can-opener comprises a plate or handle member 1, Figs. 1, 3, at the underside of which is mounted a knurled traction wheel 4 adapted to engage inside the rim of the can, the shaft of which wheel passes through a boss 2 and is fitted with a handle 5. A revoluble cutter 13 attached to a second knurled wheel 12 is carried by an arm 8 pivoted at 7, the shaft 10 passing down through an arcuate slot 11 in the plate. In the inoperative position of the parts, Fig. 1, the rim of the can is readily engageable between the wheels 4, 12 ; clockwise turning of the handle 5 from this position causes a lug 6 depending from the handle 5 to strike an upstanding lug 9 on the part 8 causing that part to turn so that the rim of the can is gripped and the cutter enters the wall, whereupon further turning cuts off the end. Reverse turning of the handle disengages the device. In the modified construction shown in Figs. 5 and 7, the pivot 25 of the cutter and corresponding knurled wheel is mounted directly at the underside of the plate and the knurled wheel 21 which engages inside the rim and in this case is the driven wheel, is carried by an arm 17 provided with a boss extending through a radial slot 19 in the handle member. Pins 23, 24 on the handle 22 and the plate coact as in the first form to bring the parts into position. In this construction resiliency is given to the arm 17 by its curved form and also if desired by making it of spring material.
