Title: Automatic safety electric circuit breaker
IPC: H01H73/30
Filed: 1926-09-22
Abstract: 275,038. Aichele, E. Sept. 22, 1926. Automatic circuit-breakers; sparking, preventing; indicators.-In an automatic cut-out the circuit is broken by a, spring-operated plunger, which is normally detained by a pawl and released by a thermostat when heated by the passage of excessive current. The current passes from a central contact 6, Fig. 2, to a plunger 7 carrying a bridge 10 perforated to slide on a pillar 11. The thermostat 15, comprising sheets of metal of different coefficients of expansion, is secured to the casing at 16 and at its other end is attached to a pawl 13 pivoted at 12 in the pillar 11. To set the cut-out the plunger 7 is depressed by a push 9 against the action of a spring 8 until the pawl 13 engages over the bridge 10, the plunger then resting on the contact 6. The connection between the terminal 16 and the screw-in socket 5 is made by a fuse wire 18. The cut-out may be adapted for stronger currents by inserting a shunt wire between the terminal 16 and the pillar 11. To prevent corrosion by sparking the contact 6 is hollowed and filled with an amalgam of equal parts by weight of mercury, lead and powdered copper or brass, the copper or brass being previously treated with dilute sulphuric, carbolic or other acid. In a modification the current passes from a central contact 6, Fig. 6, by a wire 20 to a spring blade 22, which, when conducting, rests against a similar blade on the opposite side of an insulating plate 30, Figs. 6 and 10, carried by the spring plunger 9. A lug 29 on the latter is engaged by a pawl 14 operated by a thermostat 15. When the pawl releases the plunger the plate 30 rises between the blades 22 and engages a groove 35 in the casing and the blades are further separated by wings 32 on the plunger sliding in grooves in the casing. The thermostat 15, which is approximately of M shape, is attached by feet 16 to the casing and carries at its upper end a bar 25 of insulating material engaging a slot in the head of the pawl 14. The latter is pivoted in a bracket 28 connected to the middle section of the thermostat. The wire 20 passes through an amalgam or other conducting mass 23 in a recess in the base of the casing, the mass being separated into layers by sheets 21 of insulating material. In a further modification a spring blade 38, Fig. 15, rests against a ring 37 connected to the central contact 6 while a spring-pressed insulating sleeve 39 is held depressed by the pawl 14 of the thermostat 15. When released the sleeve rises and covers the ring 37, the spring 38 being pressed aside by an inclined surface 42. The pawl can be tripped mechanically by depressing a spring-pressed button 46 into engagement with an inclined surface 49 carried by the thermostat and the apparatus can be reset by depressing the sleeve 39 by means of a plunger 9. The. position of the sleeve 39 is indicated by means of a button connected to the sleeve.

Abstract: 1,015,341. Pulse circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. June 18, 1964 [June 18, 1963], No. 24130/63. Heading H3T.  In a circuit for detection of the absence of one or more clock pulses, each pulse is used to set a bi-stable device T1 which is reset by the same pulse after a delay imposed by DL, a second delayed pulse being provided, occurring after the next pulse is due, an indication being given signifying the absence of the next pulse if the bi-stable device is still in the " reset " state at the time of the second delayed pulse. As described, 1 Ás. clock pulses at OL, occurring at 10 Ás. intervals are amplified by inverters I1, I2 and fed to a correctly terminated delay line DL which supplies pulses delayed by slightly more than 10Ás. to an emitter follower E2 and inverter 14 and pulses delayed by 5Ás. to an emitter follower E1 and inverters 13, I5. Each pulse at OL sets the transistorized bistable device T1 which is reset by the first delayed pulse. In the absence of the next pulse at OL, T1 remains in its reset state, opening an AND gate G2 which allows the second delayed pulse to set the bi-stable device T2 which provides a fault indication. The operation may be inhibited at SP and restored at RT. Delay line DL may be replaced by monostable devices.

Title: Apparatus for controlling the position of a part of a forging manipulator
IPC: B21J13/10
Filed: 1970-05-19
Abstract: 1315143 Forging manipulators SCHLOEMANN AG 19 May 1970 24245/70 Heading B3H A forging manipulator has the position of its peel 7 controlled by a piston cylinder 10, 11 suspension so that the peel is biased to a position in which a workpiece held by the manipulator is spaced above the lower die of a press during insertion of the workpiece into the press. The cylinder 10 is connected to a first pressure accumulator 13 which is connected through a control valve 18 to a high pressure accumulator 16. The valve is controlled by signals from a wheatstone bridge 22 with one arm of the bridge connected to the piston-cylinder. The piston is connected to a coil 20 and the cylinder has a slider 21. Before forging the bridge is unbalanced until the piston is at the top of the cylinder. A hand operated adjuster 27 is used to initially balance the bridge with the piston raised. The stroke of the press is set on a device 23 to ensure that the bridge is insensitive to downward displacement of the workpiece against the spring action of the accumulator 13 during forging. When, at the end of a forging stroke, the workpiece reaches its lowest point of displacement, the resistance presented from the coil 20 to the bridge 22 triggers the bridge back into a state to control the valve 18 relative to the zero position of the coil 20 in which the piston 11 is at the top of the cylinder 10. By this means, if the centre of gravity of the workpiece is displaced outwardly as a result of the forging stroke and the peel consequently adopts a lower rest position, the valve 18 is opened to drive the piston 11 back to the top of the cylinder. Once this position is reached the valve 18 cuts off and the bridge 22 reverts to its insensitive state in readiness for a second forging stroke.
