Title: An improved process and apparatus for the protection of rectifiers against excess currents
IPC: H02H7/127
Filed: 1930-10-02
Abstract: 370,405. Rectifying alternating current. LUTZ, F., 32, Sulgenauweg, Berne, Switzerland. Oct. 2, 1930, No. 29560. Convention date, Oct. 3, 1929. [Class 38 (ii).] Mercury vapour or hot cathode rectifiers are protected against overload or short-circuit conditions by means of grids associated with the anodes and so energized in accordance with load conditions that above a predetermined load the moment at which the anodes start to conduct is retarded thus reducing the output voltage of the rectifier. Fig. 1 shows a mercury vapour rectifier comprising anodes A associated with grids G and a cathode K in which retarding of the ignition under abnormal load conditions is effected by imparting to the grids a negative voltage due in part to the drop across a resistance W carrying the load current and in part to the voltage produced by a rise in load current in a transformer T, this voltage being neutralized under normal load conditions by a battery B providing positive bias. In an alternative arrangement, Fig. 2 (not shown), grid voltage is derived from a pair of opposed windings inductively associated with the circuits of different anodes. In a further arrangement, Fig. 3, in which the grids G are normally positively biassed by a battery B or an auxiliary rectifier, ignition is retarded under abnormal conditions by increase in the voltage of a condenser C opposed to the battery B and charged through rectifiers V by transformers T.

Filed: 1924-12-09
Abstract: 240,330. Western Electric Co., Ltd., (Western Electric Co., Inc.). Dec. 9, 1924. Alternating - current relays. - A voice - frequency relay comprises a coil 16 loosely suspended on a wire 14 in the field of a permanent magnet, or of an electromagnet, the wire constituting a bridging contactmember between two fixed hook contacts 17, 17<1>, in the circuit of a second relay 19. When an alternating current is applied to the coil it vibrates with the frequency of the applied current and makes and breaks contact between the hooked fixed contacts and the hooked ends of the bridging member. The bridging member may be in the form of a reed fixed at one end and hooked at the other. In the electromagnetic form a central core between the arms of the U-magnet carries the energizing winding and projects into the hollow coil 16. Specification 9712/98, [Class 40.

Abstract: 1,220,158. Endless conveyers; delivering sheets. STAHI CORP. 21 June, 1968 [17 Oct., 1967], No. 29629/68. Headings B8A and B8R. A conveyer for a stream of overlapped publications includes a first conveyer section 10; a second conveyer section 12 spaced longitudinally from the conveyer section 10 and forming a longitudinal dumping gap 14 therebetween; a dumping conveyer section 16 mounted selectively movable between a normal position bridging the dumping gap 14 and a dumping position (Fig. 5, not shown) moved generally rectilinearly of said first and second conveyer sections and opening the dumping gap 14, means 58 being operatively associated with said dumping conveyer section 16 for moving it rectilinearly between the bridging and dumping positions. In operation, a continuous stream of publications is conveyed along the sections 10 and 12 and across the dumping gap 14 when the dumping section 16 is in its normal bridging position. When the dumping conveyer section is moved rectilinearly to its dumping position the stream is conveyed along the first section 12 and downwardly through the dumping gap. The conveyer section 16 has a frame, on each side plate 46 of which, are mounted rollers 48 to enable the section 16 to be slidable on fixed slide bars 44, 44. A drive is continuously transmitted to conveyer belts 68 of the section 16, by a drive chain 82 from a sprocket 84 on the drive shaft 20 of the conveyer section 10. The chain 82 drives a stub shaft 78 which carries a sprocket 76. A chain 76 extends from the sprocket 76 around sprockets 74, 70, 74, mounted on one of the frame side plates 46 of the conveyer section 16. The sprockets 74 are guides, and the sprocket 70 is on the drive shaft. 64 of the conveyer section 16. Thus the conveyer belts 68 are able continuously to rotate while the conveyer section 16 is either stationary or moving. The conveyer section 16 is moved by a fluid cylinder 58 to its dumping position in response to the detection of a jam by a detector 86. A smooth flow is maintained by a wire pressure roll 88.

Title: Improvements in and relating to protective arrangements for electric systems employing a power transformer with distributive windings
IPC: H02H7/04
Filed: 1934-10-19
Abstract: 439,716. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Oct. 19, 1934, No. 29984. Convention date, Oct. 19, 1933. [Class 38 (v)] A protective arrangement for a three-phase circuit, which is connected to a second threephase circuit through transforming means comprising windings connected in star to each of the circuits and an intermediate closed delta winding, the windings connected to one of the circuits being distributed windings, comprises a relay connected to be energized in accordance with the current in the earth connection of one of the windings for effecting opening of circuit-interrupting means connected in one or both of the circuits. The circuit 3, which may be a high-voltage feeder, is connected to the circuit 4, which may be a low-voltage distribution network fed from other sources, through a transformer having star-connected windings 8 and an earthed neutral 11, mesh-connected windings 10 and distributed star-connected windings 9 with earthed neutral 12. Due to this distributed arrangement of windings 9 earth-fault currents flowing in one set of windings do not affect the earth connection of the other set. Relay 15 will therefore only respond to earth-faults in feeder 3 or windings 8 and operates to open breaker 7 to prevent reverse-power flow from the net into the feeder. If it is desired to open breaker 7 for earth faults in the windings 9 or circuit 4, a relay 17 in the earth connection of windings 9 is provided and is unaffected by faults in feeder 3. When a breaker 6 is provided in the latter, this may also be adapted for tripping by either relay in the manner shown or, by omitting the connection X, a selective action is obtained. In a modification, Fig. 2 (not shown), relay 15 is energized on earth fault in feeder 3 or windings 8 by zero-phase sequence currents in windings 10, and each relay 15, 17 operates only its associated breaker.
