Title: Trip arrangements for circuit breakers
IPC: H01H33/59
Filed: 1975-04-21
Abstract: 1494370 Actuating circuit breakers SIEMENS AG 21 April 1975 [19 April 1974] 16474/75 Heading H2K A circuit-breaker tripping arrangement comprises a voltage-responsive switch 7, 8 which connects a charged capacitor 4 to the release coil 1 of the circuit breaker 0 when an input voltage U falls below a certain value, thereby tripping the circuit breaker, and at the same time renders a lock-out device 3 effective to prevent reclosing of the circuit breaker. The voltage-responsive switch may be a thyristor network or a relay 7 having a contact 8 which changes over when the input voltage U is above the threshold level, thereby permitting the capacitor 4 to charge from the input voltage and energizing the lock-out device 3 (in which state it is ineffective, allowing the circuit breaker O to be closed). The circuit breaker is also tripped if a switch 15 is closed to energize the release coil 1 directly from the input voltage. The switch 15 may be operated manually, or automatically in response to a fault, e.g. over-current.

Title: Guard for the combs and other devices in cotton combing machines
IPC: D01G19/04
Filed: 1939-06-09
Abstract: 529,917. Combing-machines; guards for machinery. BIRCH, A. June 9, 1939, No. 16886. [Class 120 (i)] [Also in Group XXIV] A combing machine has a guard for the comb and associated parts of each combing head which cannot be removed until the moving parts of the machine are at rest and, while one or more of the guards are removed, the machine cannot be started; an additional guard may be provided for preventing access to a cylinder from the rear of the machine when the latter is running. As shown the guard a, Fig. 1, for the comb 2, nipper 3 and rollers 4 of each head of the machine is carried by arms a<SP>1</SP> pivoted to fixed brackets a<SP>3</SP> and carries a frame 8 pivoted in the arms a<SP>1</SP> and connected by a rod 9 to a lever 10 loosely mounted on a shaft 11 to which is fixed a lever 12 having a lateral pin 12a engaging the lever 10 when the guard is closed and supported by feet a<SP>4</SP> resting on a bracket 7. The shaft 11 extends the length of the machine and has fixed thereto a lever 13 coupled to a rod 14 provided with an actuating handle 14a and having its end disposed adjacent a member 16 fixed to the usual starting rod 15. When the machine is running, the rod 14 cannot be moved to lift the guards since its end abuts against the member 16 but when the starting rod has been shifted to stop the machine, the end of the rod 14 is in alignment with an aperture in the member 16 and can then be moved if the moving parts are at rest, to rock the shaft 11 and remove the pins 12a away from the levers 10. So long as the brush and other parts are rotating a wiper 25 on the shaft 23 of the brush engages a projection 25a on the rod 14 and pushes it forward so that its end cannot engage the aperture in the member 16. When the parts are at rest any or all of the guards can now be raised and when raised are supported by engagement with catch springs 20 on the rail 19 and the machine cannot be restarted until all the guards are lowered and the levers 10 moved to allow the rod 14 being pushed back and the end thereof removed from the aperture in the member 16 on the starting rod. So long as the brush and other parts are rotating a wiper 25 on the shaft 23 of the brush engages a projection 25a on the rod 14 and pushes it forward so that its end cannot engage the aperture in the member 16. An additional guard 27, Fig. 7, may be provided to co-operate with the plate 26 at the rear of the machine and prevent access to the cylinder until the guard a has been raised.

Title: Improvements in or relating to the treatment of coal and like materials
IPC: C10B57/08
Filed: 1932-06-17
Abstract: 407,665. Heating or drying coal, limestone, or other solid materials. FORSANS, P. E. H., 78, Rue Legendre, Paris. June 17, 1932, No. 17154. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 18, 1932]. [Classes 51 (ii and 55 (i).] In the preliminary heating or drying of coal, shale, cement slurry, limestone, or solid materials which undergo a subsequent heat treatment, the heat from a hot residue such as coke is transferred to the raw material such as coal, either by direct contact, or by heating a gas by passage through the hot coke and using the heated gas to preheat the coal. Hot coke is discharged from a coke oven through hoppers 1 and 2 into a container 3, through which a current of cold gas is forced by a fan 12 and pipe 13. The gas, thus heated, passes through a pipe 15, fan 16, and pipe 17 to the bottom of a shaft 7 down which the coal to be heated, or dried is showered from a hopper 6. The cooled gas passes through an outlet 18 to a dust separator 19, and may escape through a pipe 20, or be returned by a conduit 1 leading to the fan 12. The dust is returned to the shaft 7 through a conduit 21. The temperature of the coal may be adjusted by byepassing some of the cold gas through a pipe 22 into the hot gas conduit 15. In Fig. 2, the hot residue such as coke is fed from a chamber 3 to a shoot 4<1> in which it is joined by coal from a container 6. The hot and cold materials are mixed in a rotary drum 9<1> which at one end has perforations 11<1> through which the heated coal passes into a hopper 12<1>. The cooled coke passes through the end of the drum into a hopper 13<1>, and may be further cooled by gas from an inlet 14<1>.

Abstract: 146,163. Garnerie, J. Nov. 18, 1913, [Convention date]. Drills and cutters.-A tool for preparing holes for expanding wall-plugs comprises a holder 3 having an inclined longitudinal groove 5 in which a cutter 8 is adapted to slide. Fig. 11 shows the cutter fitted to commence operation on a cylindrical hole. As the cutting proceeds the cutter is gradually forced up its groove into the position shown in Fig. 12. A projection 9, formed on to the cutter, abuts against the wall in cases where the cutter does not reach the bottom of the hole and a spring 12 working between stops 10 and 13 may be fitted to ensure smoothness of working. Various shapes of cutter may be used to produce holes of different sections, and one cutter may be adapted to drill a plain cylindrical hole before shaping, as above described.

Title: Instrument for measuring forces
IPC: G01L1/14
Filed: 1958-05-30
Abstract: 883,206. Electrical measuring systems. MASCHINENFABRIKS AUGSBURG-NURNBERG A.G. May 30, 1958 [June 21, 1957], No. 17287/58. Class 40 (1). [Also in Group XIX] An instrument for measuring the limit value of a dynamic force comprises a coil, the inductance of which is varied by the position of a plunger coupled to the force by a one-way coupling against a restoring force, the plunger being provided with a brake. Fig. 1 shows a dynamometer loop 1 arranged to measure the maximum value of force 3. Displacement of the upper limb of the loop causes movement of a pin 4 in contact with a plunger 5 within coils 6, 7, thus altering their inductance. The plunger 5 is held in its lowest position by brake shoes 14, 15, forced against a hardened surface 12 by a spring 17. The coils 6, 7 are fed from an alternating voltage source 8 so that the coil current indicated on an instrument 9 is dependent on the maximum force. The apparatus may be reset by operation of magnetic release 16, which allows the spring 13 to restore the plunger 5 to its zero position. In Fig. 2 (not shown), the brake is permanently applied and the spring 13 rendered ineffective by a magnetic release. Fig. 3 relates to the measurement of the maximum value of a force 3 in the upward direction or the minimum value in a downward direction. The pin 4 is replaced by a hook acting on the underside of the plunger 5. The compression spring 13 is replaced by a tension spring. The embodiment of Figs. 1, 3 may be combined within a single measuring loop 1 so that maximum values of a force in each direction may be indicated on separate instruments or on a single instrument switched to the appropriate coil.
