Title: Improvements in or relating to protective systems for electrical apparatus
IPC: B23K11/24
Filed: 1943-07-01
Abstract: 564,469. Protective cut-out arrangements. BUDD MANUFACTURING CO., E. G. July 1, 1943, No. 10702. Convention date, July 4, 1942. [Class 38 (v)] Failure of one of a pair of grid-controlled, reversely-connected valves 15, 16, shown as ignitrons in the circuit of a welding-transformer, causes opening of the circuits controlling the timed actuation of the grids 19, 20. The latter are connected to a timing-control means 23 for energizing them alternately, the control, circuits including gas-discharge tubes 24, 25 having their grids and cathodes connected to the means 23 and their anodes connected to the respective anodes of the valves 15, 16. The protective 'means comprises a saturable reactor 31 in series with a solenoid 33, which may be shunted by a capacity 32, and, as shown, a pair of reverselyconnected vacuum tubes 51, 52. When a valve fails, the normal alternating current in transformer 10 and reactor 31 is replaced by a series of unidirectional impulses which, owing to the retarded decay of flux in the non-conducting periods, causes a cumulative build-up of flux and hence core-saturation in reactor 31, so lowering its impedance. The resulting voltage increase in solenoid 33 opens at 41 the circuit of solenoid 35 which, at contacts 37, 38; disconnects the anodes of tubes 24, 25 from the main valves and so puts them out of operation. A manual switch 42 energizes solenoid 35 to restore the supply. The grids 54, 55 are preferably transformer-connected to a phasedisplacing circuit 62, 65, whereby the tubes 51, 52 only conduct for a small part of the halfwave in the neighbourhood of voltage-zero. In a simple form, these tubes and associated circuits are dispensed with, Fig. 1 (not shown). The invention is illustrated by a set of curves, Figs. 3-6 (not shown).

Abstract: 987,058. Feedwater supply systems for steam boilers; cooling burners. SULZER BROS. Ltd. March 16, 1964 [April 2, 1963], No. 11041/64. Headings F4A and F4T. In the feedwater system of a steam boiler the regulating valve in the main feed line is bypassed by a conduit containing heat exchange means wherein the by-passed water is used for cooling purposes. Thus it may be used for cooling structural parts of the boiler, burners or in surface heat exchangers used for regulation purposes. In the form shown, a feed pump 1 feeds water through preheaters 2, 3, a pipe 4 containing a restrictor 5 and a regulating valve 6 to the economizer 7 whence it flows through the evaporator-superheater 8, steam discharging to the point of use at 9. The burner 10 of the boiler is protected by a cooling coil 11 receiving water through a pipe 12 branching from the pipe 4 between the restrictor 5 and the valve 6, the water returning to the main feed circuit downstream of the valve 6 through a pipe 13, the flow through the by-pass being established by the pressure drop across the valve 6. The latter is controlled according to load and temperature sensed at 16 whilst the flow through the coil 11 is controlled by a valve 19 which is set according to load or according to the temperature of the burner. In a modification the pipe 12 branches from the main feed line before the preheaters so that cool water flows to the coil 11. In a further modification, the pressure drop across the feed regulator valve 6 is controlled at a constant value for each load reducing fluctuation in the by-pass, the control valve in which may be omitted.

Abstract: 256,182. Bassick Manufacturing Co., (Assignees of Davis, E. W.). Aug. 1, 1925, [Convention date]. Actuating by weights and springs ; single-acting suctionvalveless piston pumps ; air vessels. -In a system wherein a pump supplies lubricant to a. branched conduit, lubricant supplied to each branch pipe 100, Fig. 6, depresses a spring-pressed stepped plunger 104 arranged in a chamber 102, whereby a definite charge of lubricant contained beneath the plunger is ejected through a non-return valve 112 into a chamber 118 communicating through a channel 128 with a bearing 130. After each discharge stroke of the supply pump, the plunger 104 rises and lubricant above it passes into the chamber beneath it through the clearance to provide a new charge. The chamber 118 contains an inverted cup 120 having notches 124 permitting flow of lubricant to the channel 128. According to the resistance of the bearing, lubricant accumulates in the chamber 118 and compresses air in the cup 120. By this arrangement, the pressure of lubricant supplied to the bearings varies with the resistance of the bearings. An upright cup 122, having notches 126 in its base, may be arranged in the cup 120 to act as a plunger. A supply pump adapted to be mounted on a motor-vehicle comprises a piston 44, Figs. 3, 5, movable in a cylinder 40, the discharge stroke being effected by a spring 56 and the suction stroke by a cam 46 engaging a recess 48 in the plunger. The cam is mounted on a shaft 62 driven through worm gearing 66, 68 from a shaft 70. A weight 76 pivoted on the shaft 70 and kept normally in the position shown in Fig. 3 by a spring carries a pawl 88 co-operating with a ratchet wheel 74 mounted on the shaft 70. During movement of the vehicle, vertical oscillations of the weight 76 cause the shafts 62, 70 to rotate. A screw 96 engaging a slot in the piston prevents rotation of the latter and may be tightened to lock the piston.
