Title: Improvements relating to d.c. arc welding apparatus
IPC: B23K9/073
Filed: 1956-09-05
Abstract: 874,074. Supply systems for welding arcs. HIRST ELECTRONIC Ltd., HOLDEN, E. J., and MORRIS, J. D. Dec. 5, 1957 [Sept. 5, 1956], No. 27229/56. Class 38 (4). A D.C. arc welding circuit has its electrodes 12, 16 connected to a generator 10 which also charges a large capacitor 20, preferably of the electrolytic type, which discharges into the arc, striking with sufficient energy to maintain it during the voltage recovery period of the generator. High-voltage arc initiating impulses in series with the capacitor discharge are provided by a circuit comprising transformers 35, 55, capacitors 51, 60, rectifier 48, and strobotron 50, which discharges to the weld alternate half cycles of energy through a capacitor 61, the energy release being cut off through relay circuits 41, 43 when the weld voltage falls. The impulse energy is discharged periodically through a spark gap 59, capacitor 62, and an output impedance 14, capacitor 62 acting as a radiofrequency by-pass to the capacitor 20. The radio interference of the impulses is reduced by the partial rectifying action of capacitor 20 which has a series resistor 44 to lengthen the discharge time. The relay circuits 41-43 may also operate a timer controlling the welding period.

Title: Improvements in and relating to automatic fire sprinkler installations
IPC: A62C35/60
Filed: 1923-10-31
Abstract: 206,501. Earle, A., and Cox, E. A. Aug. 30, 1923, [Convention date]. Sprinklers, automatic; water supply to pipes. - The pressure of the water supply to an automatic sprinkler installation is maintained by an additional water supply when the main supply fails, and excess pressure is prevented from passing on failure of the mechanism. The main supply to the sprinkler pipe 6 is by way of a pipe 3 and a non-return valve 4, and when the pressure in a chamber 5 falls owing to a fall in pressure in the main supply, a piston 8 descends and allows an arm 26, disposed in guides 25, 28 and acted on by a weight 30, to pivot about pin 27, and thus permit the rising of a valve 18 which controls the additional supply through a pipe 17 and ports 19, 14. In this way the pressure in chamber 5 is re-established, whereupon the valve 18 is reclosed by the piston 8 and lever 26. On failure of the mechanism, overcharging of the apparatus is prevented owing to a shoulder 31 of the valve 18 being pressed up against a face 32. In this position the lower part of the valve closes the ports 14 and the ports 19 are opposite a dead-end port 15. A relief valve 11 is provided. Springs &c. may be used instead of the weight 30 and lever 26. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the modification shown in Fig. 2 (Cancelled), wherein the plunger 37 is acted on by the fall of pressure in chamber 5 and weight 41 to open communication between the additional supply 17 and the sprinkler pipe 6 by ports 38. A relief valve 11 is provided. This subject-matter does not appear in the Specification as accepted.

Filed: 1975-07-01
Abstract: 1478574 Fluid-pressure servomotor systems PARKER-HANNIFIN CORP 1 July 1975 [15 July 1974] 27709/75 Heading G3P [Also in Division F2]  In a valve assembly for inter-connecting a fuel hydrant valve 4 to an aircraft fuel-tank filling hose 3 a pilot controlled valve 10 is opened by first opening a poppet valve 5 by rotating a shaft 6 and then opening a "dead man" valve (not shown), to apply a reference pressure to line 11. This action closes a "fast-closing" pilot valve 15 and an "excess flow and surge control" pilot valve 17. A main "pilot control" valve 25 is also opened to vent a chamber 27, via a variable orifice 28, so that the main valve 10 opens against a loading spring 31. Pressure in the delivery hose is fed to the pilot valve 25, via a line 9, so that, depending upon the setting of a spring 34 in the pilot valve, a constant pressure is maintained in the delivery hose. On release of the "dead man" valve the "fastclosing" valve 15 opens and pressure fuel is admitted to the chamber 27 via a check-valve 37, to close the valve 10 rapidly. In opening of the valve 10 this check-valve will have been opened but as the valve 10 closes this valve will close leaving pressure for the final part of the closing movement to build up through a restriction 38 and a check-valve 39 with an adjustable loading spring. Should pressure in the delivery hose surge to above a predetermined level, e.g. as a result of a sudden closure of a liquid-level controlled valve at the far end of the delivery hose, valve 17 will open to admit pressure fuel into chamber 27 to close the main valve 10. Should the flow-rate exceed a predetermined level the pressure differential across a Venturi 45 will move a diaphragm 42 in an "excess flow" servovalve 12 to actuate a valve-member 21 to a position in which it cuts off the reference pressure from the excess flow pilot valve 17 which then opens to effect closure of the main valve 10. A lever 14 serves to reset the valve-member 21. A further lever 43, having a detent (not shown), serves to hold the diaphragm in the high flow-rate position.  A relief valve 7 relieves pressure in the chamber 48 when the coupler poppet valve 5 closes.
