Title: Improvements in electric protective systems and apparatus therefor
IPC: H02H3/08
Filed: 1927-04-23
Abstract: 270,678. British Thomson-Houston Co., Ltd., (Assignees of Traver, O. C.). May 4, 1926, [Convention date]. Protective arrangements.-Means are provided positively to prevent opening of circuit-breakers on sound sections of a system consequent upon current surges arising from the opening of circuitbreakers to disconnect faulty sections. Excess current in the feeder 4, when power is outgoing in that feeder from the bus-bars 3, causes the overcurrent relay 7, which may have a time limit, to close, and the directional relay 8 to close its contacts 17, thereby completing the circuit of the trip coil 6 of the circuit breaker 5 which opens to disconnect the feeder. If excess current occurs when power is incoming, the relay 8 closes its contacts 15 and the circuit-breaker 5 is not opened, but when the fault is removed elsewhere there is the possibility of a current surge occurring in the system and causing transient excess current in an outgoing direction in the feeder, and it is desired that this transient current shall not open the circuit-breaker 5. Therefore, where the contacts 15 are closed the coils of an instantaneous pick-up device 23 are energized and its member 26 locks the relay 8 in the closed position. After the relay 7 opens, the member 26 sinks slowly owing to a dash-pot 27, and thus the relay is not free to move until sufficient time has elapsed for the surges to dissipate. The device 23 also functions when the contacts 17 are closed, thereby ensuring that the tripping circuit is broken at contacts 28 and not at the contacts 17. A similar system is employed for protecting parallel feeders, the overload relay and the current coil of the directional relay being connected to normally equipotential points in a circulating circuit, and the two sets of contacts on the directional relay being connected respectively to the tripping coils of the two circuit-breakers, one in each feeder. Specification 221,946 is referred to.

Filed: 1933-04-12
Abstract: 405,830. Non-contact-making relays. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. April 12, 1933, No. 10993. Convention date, April 18, 1932. [Class 40 (iv).] The windings W1-W6 of an amplifier MV, in which modulation of a higher frequency is followed by detection, are connected as a differential transformer between a two-way line L, two single-way lines and a network N balancing the two-way line. The iron-core of the inductances is biassed by a battery B, so that incoming signals in the windings W1, W2 alter their impedance to a high-frequency from a generator H. The modulated high-frequency currents are rectified at Gl2 and the amplified signals applied to a receiver ER. For transmitting, keyed alternating current from a generator SG is delivered to a rectifier Gl1, and the signals flow through the two halves of the windings W1, W2 in opposite directions and thus have no effect on the receiver.

Title: Improvements in or relating to brush filling machines
IPC: A46D3/04
Filed: 1921-04-15
Abstract: 182,946. Shipley, A. H., and Berry, A. B. April 15,1921. Brush-making machines.- In a brush-filling machine, a device for separating each selected knot of bristles from the main supply consists of a pair of fingers adapted to penetrate between the material and the selected knot and to move in opposite directions away from the point at which the knot is held. In the construction shown in Figs. 1 and 2, the bristles 2 are disposed verticallv and the selected knot 2a is transported in an horizontal direction by needle-bars 3, 4. The fingers 1 are pivoted at 5 to a block 6 attached to a slide 7, each finger being connected by a link 9 to a block 10 slidable within a groove 12. The length of the groove is less than the length of movement of the slide 7, so that, as the slide is moved forward, the fingers move forward without oscillation until the block 10 contacts with the end of the groove, when the fingers separate, dividing the ends of the knot from the supply. The slide 7 is reciprocated by means of a pivoted lever 15 connected thereto by a screw 17 and actuated by a link 18 pivotally connected to a reciprocating part 20 of the machine. The link 18 is connected by a bolt and slot arrangement to the lever 15, so that the movement imparted to the slide 7 may be varied. In a modification, the slide 7 may be provided with rack teeth meshing with a toothed quadrant adjustably connected to a link pivoted to a reciprocating part of the machine. In the construction shown in Figs. 7 and 8, the fingers 31 are disposed parallel to the plane along which the selected knot 2a is transported. The fingers are pivoted at 32 on a rotatably-mounted block 33 having a projecting arm 37 provided with a spring-pressed roller 38 engaging a cam-slide 40 attached to the needlebar 4. The extremities 31<a> of the fingers are bent at right angles, as shown, and the rear ends are provided with interengaging teeth 31<b>. The lower finger engages a toothed quadrant 41 adjustably connected to a reciprocating link 43. When the needle-bar 4 moves forward to pick off the knot 2a, the cam-slide 40 acts on the roller 38, causing the fingers to oscillate so that the ends 31<a> pass between the knot and the supply. The link 43 then actuates the fingers so that they diverge and separate the ends of the knot. With regard to the reverse movements, the link 43 may be actuated to close the fingers either before or after oscillation. Reference has been directed by the Comptroller to Specifications 1075/71 and 1771/03.
