Abstract: 1,182,412. Protective arrangements. ENGLISH ELECTRIC CO. Ltd. 4 May, .1967 [5 Feb., 1966], No. 5160/66. Heading H2K. [Also in Division G1] Current in a high voltage line is measured by producing an A.C. carrier signal modulated in a manner representing the value of the current, and coupling this signal through a capacitive coupling incorporating series connected capacitors to a demodulator at low voltage which receives the carrier signal and translates it into an output representing the current value. The current at high voltage on line 12 is transformer coupled at 42 to a voltage-frequency converter contained in the transmitter arrangement 41, the derived frequency being used to modulate a carrier frequency in the transmitter, which is supplied from a pack 48. The output from the transmitter 41 is coupled to a bifilar wound transformer 16 tuned to the carrier frequency and is transmitted via the series capacitor columns 24, 34, to a further bifilar transformer and thence to an output demodulator 44. Power is supplied from an oscillator 45 at a different frequency to that of the carrier frequency via the tuned transformer circuits 18, 17 to the pack 48, where it . is rectified and smoothed before being supplied to the transmitter 41. The bifilar transformer windings are such that the inductances of the windings relative to through currents cancel. The transformercapacitor system 11 may be used in a carriercurrent protective system. The output of demodulator 44 may operate a relay.

Title: Improvements in and relating to protective devices for electric circuits
IPC: H02H7/26
Filed: 1930-02-18
Abstract: 347,795. Protective cutout arrangements. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Fitzgerald, A. S. ; 1212, Union Street, Schenectady, New York, U.S.A.) Feb. 18, 1930, No. 5452. Convention date, Feb. 19, 1929. [Class 38 (v).] In a protective system in which high-frequency control current is superimposed on the line and has at each protected point a directional relay the two windings of which are energized respectively by the current corresponding to a characteristic of the protected circuit at that part and by a current in accordance with a demodulated carrier wave transmitted from another point, e.g. the remote end of the protected section ; the directional relay contacts are normally biased to a closed position, and an additional relay is arranged in series in the directional relay control circuit, which additional relay is normally open but closes with an abnormal value of the characteristic of the main circuit in the adjacent portion of the section. Different frequencies may be transmitted from the opposite ends of the potential section. As shown in the Figure each end of the section 1 is provided with a direction relay 11, 110 having coils 25 energized directly from local current transformers and coils 26 energized from demodulated carrier waves which are transmitted from opposite ends of the section. The carrier waves are produced by oscillation generators 14 operating in conjunction with modulating valves 16. the grids of which are controlled according to voltage variations at the ends of resistances 24 included in the circuits of the adjacent current transformers 9, 90. Each end of the section is also provided with a receiving valve 21 the plate current of which feeds the coil 26 of the local directional relay through a transformer 32, the receiving circuit at one end being tuned in accordance with the carrier wave transmitted from the other end of the section. Thus a comparison of the direction of flow of power is made in the directional relays which are arranged so that in the case of a through fault the directional relays prevent the completion of the tripping circuit by opening their contacts 33, but permit tripping by remaining in their normally-closed position in the case of an internal fault. The tripping circuits in each case, in accordance with the invention, are finally completed at contacts 37 of time-lag overload relays 36, may also operate to produce tripping independently of the directional relays, as, for example, in the case of a break in the line 1. The transmitting end receiving valves at each end are cut in by overload relays 27 at each end so that if power is fed from one end only the directional relay at that end cannot be opened.

A mobile overhead loading device for loose material comprises a scoop 13 on the end of an arm 12 pivoted to a second arm 9 pivotally mounted on a chassis 1 provided with a platform 2 on which the vehicle to be loaded is supported. The platform, Fig. 1, may comprise two girders 2 with mounting plates 3 for the wheels of the vehicle. The levers 9 and 12 are operated by hydraulic cylinders 15 and 14 respectively. In the embodiment shown in Fig. 3, the scoop 41 is mounted on arms 35, 37 pivoted to arms 31, 34. The arm 31 is mounted to rotate freely on a shaft 28 integral with a drum 30 and its lower end is connected to a piston rod 52 having a piston moving in a cylinder 54 mounted on a rotatable base 25. The piston has a ball valve 56 and the ends of the cylinder are connected by a pipe with a valve 61. The arm 34 is pivoted to an arm 32 fixed to the shaft 28. An arm 43 is pivoted to an arm 42 secured to the shaft 28 at one end and at the other end is secured to an arm 46 pivoted to the lever 31. A rope wound on the drum 29 is pulled to rotate the drum anti-clockwise and the scoop rotates until a stop 48 on the arm 46 contacts the lever 31. If the valve 61 is then opened, the arm 31 rotates and the scoop is discharged in the vehicle. The valve 61 is closed to retain the arm 31 in position and the drum 29 can be rotated clockwise until the stop 50 on arm 35 abuts the arm 31. The valve 61 is then opened and the arm 31 returns to its original position. In a modification the pipe and valve 60, 61 are dispensed with and an oil filled cylinder pivoted to the base is urged to engage a stop on the arm 31 to limit its downward  movement. The cylinder has a comperisating cylinder with a manual-operated ball valve whereby oil passes from one cylinder to the other and allows the arm to be lowered further.
