Title: Improvements in electric fuses
IPC: H01H85/20
Filed: 1921-03-04
Abstract: 182,512. Fuller, H. J. March 4, 1921. Fusible cut-outs.-The rupture of the are occurring in fuses on heavy short-circuit, is attained by one or more shields having contiguous faces of adequate width in the direction of the length of the fuse which come together under gravity, spring, or other self-adjusting pressure, and are reversible or removable br both. In certain forms, particularly for high and extra-high voltages, the shields enclose the fuse terminals. The fuse tract is preferably unenclosed. The meeting faces consist 0f such materials as those known under the registered Trade Marks " Asbestone," Urolite," " Hobsleyte," "Eternit," or they may be of woven asbestos. They may have interfitting serrations to assist in breaking up the arc. As shown in Fig. 2, two shields D, D' are used adjacent to a terminal, pressed together by springs E at each end; the shield D<1> is reversible. Fig. 5 shows a shield in three parts D, D', D<2> entirely enclosing the terminal and being rotatable as a whole to provide fresh faces in. contact with the fuse F. Fig. 4 shows in place. two shields D, D' with removable and reversible pieces d, d' pressed upon the fuse by a blade spring E. The bridge fuse shown in Fig. 9 has pairs of rotatable and reversible washers d, d pressed between two members D, D<1> by springs E at each end. Fig. 14 illustrates a section of two washers or rings d, d' with mating grooves and Fig. 16 is a fragmentary view showing an. arrangement of woven asbestos washers.

Patent GB-721300-A (GB)
Title: Improvements in automatic electric switches having overload release means
IPC: H01H73/50
Filed: 1952-03-19
Abstract: 721,300. Automatic circuit-breakers. LEYHAUSEN, W. March 19, 1952, No. 7064/52. Class 38 (5). An automatic switch comprises a rectangular base 1, a contact chamber 3, a magnet coil 7 at the side of the contact chamber, thermal overload release means including a bimetal strip 9, the chamber, coil and strip being arranged in the space below that within which the switch actuating mechanism alone is located. In the Figs., the contact chamber 3 and a combined blow-out and overload release coil 7, Fig. 2, are carried in an inverted U-shaped frame 2 and the actuating mechanism is carried in an upright U-shaped frame 14, the bases 12, 13 of the frames being secured together. The chamber 3, Fig. 9, houses fixed contacts 4, 5 and a moving bridging contact 6, the chamber having arc cooling ribs 38 and vent apertures 37. The coil 7, with its core 48, is supported by a member 50 with projecting portions 51, 52, Fig. 1, which co-operate with the bifurcated limb 54 of the lower frame to positively locate the coil assembly. The actuating mechanism comprises an .operating lever 68, Fig. 25, with a forked member 66 carrying a pin 72 which engages a pivoted lever 73. An overset toggle 77, 79 is connected between the lever 73 and a bell crank lever 45 biased by a spring 91, Fig. 1, and connected to the moving contact 6 by a bar 43, Fig. 9. In the event of a severe overload the coil 7 attracts an armature 8 so that an extended portion 65 of the armature strikes a lug 81 on the toggle link 77. The toggle 77, 79 collapses and the spring 91 turns the lever 45 to open the contacts. In the event of a smaller overload, the bimetallic strip 9 bends and pivots a pawl 99 to release a lever 95. The lever 95 is pulled upwardly by a spring (not shown) and a projecting part 98 of the lever collapses the toggle 77, 79 to open the contacts. It is stated that when the switch is tripped, the direction of the pressure which the link 77 exerts on the lever 73 changes from that exerted when the toggle is in the dead centre position so that the lever 73 can turn the lever 68 to reset the switch. In a modification, Figs. 26, 27 (not shown), the lower part of a housing is divided into three compartments containing respectively the contacts, the coil, and the armature together with the bimetallic strip. The upper part of the housing is separated from the lower part by a partition and contains the actuating mechanism which is operated by a push-button. A further push-button is provided for manual tripping of the linkage.

Patent GB-235934-A (GB)
Title: Improvements in and relating to forced draught or ventilating systems and apparatus therefor
IPC: F23L13/00
Filed: 1924-03-21
Abstract: 235,934. Neild, G. A. March 21, 1924. Forced ventilation; valves, actuating. - The shutter mechanism, comprising a number of simultaneously operated, pivoted louvres 1, for controlling the inlet or discharge conduits of a forced draught or ventilating system, is operated by an external source of power so as to open automatically when the fan supplying the system is started and to close when the fan is stopped. Each louvre 1 is connected by a link 2 to a rod 3 which is connected by means of link 4<a>, pivot pin 6, link 4 and rod 7 to a piston-rod 8, the piston 9 operating in a cylinder 10 against the action of a spring 11, which tends to keep the shutter closed. On starting the fan, and whilst the fan is in action, steam or oil under pressure from the lubricating system of the prime mover is supplied to the cylinder 10 and forces the piston 9 upwards against the spring 11 to keep the shutter open. In a modification, an electric solenoid is employed in combination with a spring or dashpot, so arranged that closure of the supply valve or operation of the emergency tripping device of the prime mover will, as desired, break or make a circuit controlling the solenoid mechanism. A hand-operated lever may be secured to the rod 3 to allow the shutter to be operated by hand independently of the automatic operation. The invention is stated to be particularly applicable to a system in which forced draught is supplied to the boilers of a warship, the air being supplied by a number of fans each driven by a high speed prime mover, the shutter mechanism of any particular fan being automatically closed in the event of that fan being put out of action.

Abstract: 1,131,190. Temperature alarms. PYROTECTOR Inc. 20 Feb., 1967 [4 April, 1966], No. 8026/67. Heading G4N. Heat-sensing apparatus for detecting and responding to different predetermined temperatures in respective ones of a plurality of locations under surveillance comprises a plurality of temperature sensing devices such as thermistors 16, 16a, 16b which are responsive to a change in temperature, each thermistor being connected in series with a resistor 18, 18a or 18b through a common junction 20, 20a, 20b, and a diode 22, 22a or 22b connected between each of the common junctions and the alarm relay coil through an amplifier 12.

When the increase is sufficient, the corresponding diode conducts and amplifier 12 operates alarm relay 10. Resistor 26 is provided so that the voltage required at the base of transistor T1 to actuate the alarm may be adjusted. The rise in temperature of any of the thermistors 16, 16a, 16b which is necessary to effect the predetermined charge in applied voltage is determined by the value of resistance 18, 18a or 18b associated with each thermistor. At least one of the resistances is adjustable so that the temperature at which each thermistor actuates the alarm may be different from that of each other thermistor.
