Title: Improvements in or relating to electric protective systems
IPC: H02H3/34
Filed: 1935-08-09
Abstract: 460,046. Protective cut-out systems. GENERAL ELECTRIC CO., Ltd., and BARRELL, F. Aug. 9, 1935, No. 22575. [Class 38 (v)] For protecting an A.C. circuit, the sum of the currents in different parts of which is normally zero, means are provided adapted to sum the currents in the said parts, or currents proportional thereto, together with relay means including an operating coil energized by an unbalanced component of A.C. arising when the sum of the currents is not zero, the relay means being biassed or restrained by D.C., a function of the currents in the said parts. As applied to a three-winding transformer 1, serving as the junction of three A.C. lines 5 ... 7 connected to star-connecting windings 2, 4 and a mesh-connected winding 3, three relays 8 ... 10 are provided, each associated with a particular phase of the three lines. The relays are of the biassed-beam type, having their trip contacts 30 ... 32 connected in parallel in the circuit of the winding 33 of a trip relay having normally-closed contacts 34. When operated, the relay latches itself in the position where it closes contacts in the circuits of trip coils of the breakers 27 ... 29 controlling the lines, these circuits being made over back-contacts which are closed when the associated breaker is closed. Each relay has three biassing windings, as 11 ... 13 in the case of relay 8, which at one end are connected, respectively, to one winding of mesh-connected current transformers 20, 22 and a star-connected current-transformer group 21 in the lines 5, 7, 6, and at the other end to an operating winding, as 24, the other ends of the operating windings being connected to the star point of transformers 21. The biassing windings are shunted by rectifiers 23 of the metal oxide type so as to be energized by direct current. Normally, the sum of the currents flowing through the biassing coils of each relay is zero and no current traverses the operating coils. If a leakage occurs in the transformer 1 a corresponding current flows through the biassing and operating coils of two relays, whereas if an interphase fault occurs, all three relays are affected. The electrical bias gives stability on heavy through loads due to external faults, and to give stability on no load and light loads, a movable beamfulcrum or other mechanical bias may be employed. Fig. 2 shows how the invention is applied to the individual line, the biassing coils 52 ... 54, shunted by rectifiers 23, being connected to the current transformers 46 ... 48, and the operating coil 56 being connected in the neutral conductor.

Abstract: 1,111,477. Endless conveyers. J. M. LEACH. 20 May, 1966, No. 22705/66. Heading B8A. A material conveying system comprises a single endless track 12 around which a series of spaced but flexibly linked trolleys 42 are movable, a material conveying magazine 14 pivotally suspended from each trolley, filler openings 20 in the magazines, and movable closures 70 associated with the openings to facilitate material feeding to the magazines when the latter pass under a hopper. The magazines 14 are spaced apart to facilitate free movement of the magazines through a curved path but this space is closed as it passes under the hopper. The members closing this space comprise a trough 90 permanently mounted on the magazine in the position shown, and troughs 82, 84 mounted on adjacent magazines and pivotable about end studs 56. The closures 70 are integral with the pivotable troughs 82, 84 whereupon due to cam rollers 76 engaging cams on approaching the filling area, the closures 70 are opened and the troughs 82, 84 are moved into the closing position shown. The feeding nose of the hopper fits into the troughs 82, 84, 90 to shut off the feed between magazines and trough-shaped slots in the end walls of the magazines permit the hopper nose to pass into the filler openings 20. A scraper and brush on the nose of the hopper clear any material left in the troughs 82, 84, 90. A discharge opening in the base of each magazine has a closure member constructed and operated in a manner similar to the filler opening. In a further embodiment. Figs. 11-12 (not shown), an endless flanged belt is provided to run between the hopper nose and the magazines in the filling area. Cut-outs in the belt are synchronized to move with the filler openings in the magazines and the space between magazines is closed by the filled-in areas of belt. In this embodiment the troughs are not required. In another embodiment, the supply of material from the hopper is controlled either by an electronic ally operated valve or by a dribble-free pneumatically operated valve, Figs. 14, 15 (not shown). The latter comprises a body having a throughway extending down from the hopper nose and a pair of plates, vertically displaced from each other and transversely movable into the throughway from opposite sides thereof one after the other. A cavity is formed between the plates to catch any material which dribbles through the upper plate.

Abstract: 835,024. Photo-electric width-measuring apparatus. EXATEST GESELLSCHAFT FUR MESSTECHNIK. July 23, 1956 [July 23, 1955], No. 22788/56. Addition to 787,385 and modified by 810,982. Drawings to Specification. Class 40 (3). In a method of measuring the width of material, wherein one television camera scans one edge and another television camera scans the opposite edge of the material and the resulting images are superimposed in intersecting relationship one upon the other on the screen of a single television receiver so that any variation in the width of the material causes displacement of the point of intersection of the images of the edges on the receiver screen, the line deflection coils or the image deflection coils of the two cameras are connected in series, or in the case of electrostatic deflection, the line deflection plates of the two cameras are connected in parallel. By such arrangements, non-identical scanning in the two cameras is avoided so that transverse movement of the material as a whole does not result in movement of the point of intersection in a direction which indicates a change in width. The distances of the two cameras from the material must be such that the projections of the scanning velocities on to a line perpendicular to the edges of the material are equal.

A normally closed electromagnetic valve controls the connection of the chamber to a volume of gas at a pressure different from atmosphere. As shown in Fig. 1, a chamber 40 is defined by a steel movable wall 32 and a light alloy body 30 joined by corrugated bellows 31. The wall 32 can be linked to an engine throttle cable by a bracket 35. A cavity 41 has an orifice 43 which admits air into the chamber 40 through a plastics foam filter 42, and contains an electromagnetic valve comprising a solenoid 46 and an armature 50 which is normally biased by a U-shaped spring member 52, Fig. 2 (not shown), so as to close an orifice 45 communicating with the air inlet manifold of an engine at sub-atmospheric pressure. In use, the solenoid 46 receives a succession of variable width electrical pulses from a vehicle speed sensing circuit, Fig. 3 (not shown), causing the electromagnetic valve to be opened and closed, thereby admitting pulses of reduced gas-pressure into the chamber 40. The actuator effectively integrates the pressure pulses and the wall 32 is moved smoothly against the action of a spring 37 so as to control the engine throttle setting. In a modification, the bellows 31 and movable wall 32 may be replaced by a piston sliding within a rigid side wall. The vehicle speed responsive circuit of Fig. 3 is described and claimed' in Parent Specification, see Division G3.
