Title: Fluid control valves
IPC: E21B34/02
Filed: 1961-06-29
Abstract: 947,897. Fluid-pressure servomotor control systems. R. S. WILLIS. June 29, 1961 [April 10, 1961], No.23611/61. Heading G3P. [Also in Division F2] The control of fluid flow from an inlet 19, Fig. 2, to an outlet 21 is effected by a main valve 24 having an integral actuating piston 29, the regulation of fluid pressure to and from which is determined by a pair of pilot valves 101, 201, respectively. The inlet chamber 54 of the valve 101 is connected to both a pressure gauge G and the main valve inlet 19 via a passage 68 and a manually adjustable valve 71. The stem 100, 200 of each pilot valve is connected to a spring-loaded piston 109, 209, Fig. 5, respectively, and the pressure gauge pointer is coupled to a contact 401a or 401b. Upon the occurrence of an abnormal gauge pressure one pair of contacts 401 make to cause energization of a relay coil 303 so completing a circuit to an electric motor Ml which drives a pump P1 that supplies fluid to actuate the piston 109 and unseat pilot valve 101, Fig. 2, so that fluid in chamber 54 passes through a port 28a to act on the piston 29 and close the main valve 24. Closing movement of the stem 100 actuates a limit switch 502e, Fig. 5, and shuts down the motor Ml whereupon the piston 109 is spring-urged to reseat the pilot valve 101, Fig. 2. When a switch 307, Fig. 5, is manually or otherwise moved to the dotted-line position the circuit to the motor M1 is broken and that to another electric motor M2 is made, concomitantly the relay 303 is de-energized; motor M2 drives a pump P2 which translates piston 209 so unseating the pilot valve 201, Fig. 2, whereby the fluid above the main valve piston 29 is exhausted through a port 33a and the main valve 24 reopens. When the stem 200, Fig. 5, operates a limit switch 501c the circuit to motor M2 is broken and the piston 209 is spring-urged to reseat the pilot valve 201. The relay coil 303 may also be energized over a manual switch 305. The position of the main valve is indicated by a rod 80, Fig. 2, extending out of the valve casing from the piston 29. An isolating valve is associated with the gauge to enable the latter to be removed; the pilot valve assemblies may also be removed upon closure of manual valve 71. The switches 305, 307, Fig. 5, are housed in a control box which may be remotely disposed. Specification 914, 111 is referred to.

Abstract: 517,944. Prepayment mechanism. UNITED GAS INDUSTRIES, Ltd., SMITH, N. L., SMITH,. D. G., (Representatives of SMITH, E. W.), CHARLES, A., and CHRISTIAN, A. J. Aug. 11, 1938. No. 23718. [Class 27] In prepayment mechanism, for use in the supply of commodities, of the type including a . basic charge and a quantity charge, means are provided for allowing a limited quantity of gas &c. to be supplied after the basic charge prepayment has been exhausted. The means may consist of an obturator q which is mounted on a shaft r so as to be swung to close the slot through which coins are discharged from the quantity prepayment mechanism. A spring r' tends to keep a pin r<2> on an arm r<1> fixed to the shaft r always against a cam o<2> mounted on the Geneva-stop star wheel shaft of the basic charge mechanism. The cam o<2> is so shaped that when the pin r<2> bears on its exterior edge the obturator is inoperative, but when by reason of the rotation of the cam the pin enters an opening in the cam leading to a circular concentric slot the obturator q closes the coin slot, this occurring when the prepaid basic charge becomes exhausted. On a coin being now inserted in the commodity supply slot this mechanism can make a movement only to the extent of the value of the coin and cannot be returned for another coin till prepayment of basic charge has been made' to withdraw the obturator q and release the trapped coin. Excess prepayment of basic charge is allowed for by allowing the pin r<2> to ride on the concentric exterior of the cam o<2>, but . a limit is put on this by a second obturator s on the shaft r which is brought up to close the basic charge coin slot. A time control for the basic charge is shown consisting of a dry battery m operating a clock k driving the worm spindle j through pinions mounted on rockable arms which permit change of gear to suit different basic charge rates. A moving drum indicator may be provided to show on a scale the amount of credit or debit for the basic charge. Specifications 387,678, 392,530, 400,636, 405,302, and 510,549 are referred to.

Abstract: 616,798. Making composite metal strip. KINNEY, J. Sept. 17, 1945, No. 23923. Convention date, Sept. 20, 1944. [Classes 83 (ii) and 83 (iv)] Welding; soldering.-A method of continuously bonding stainless steel and a non- ferrous metal such as copper to produce a composite strip, comprises forming strips of the metals, processing the surface which are to be in contact so as to remove oxides and extraneous material, bringing such surfaces together in air-excluding contact, heating the strips to at least the annealing temperature of the steel and then subjecting them to a rolling operation at that temperature. Two stainless steel strips 7, Fig. 1, are drawn from coils 7a and 7b, passed through a pickling bath 8, which may comprise part of an electro-plating apparatus, and are then fed to rolls 12 with an interposed copper strip 11 from a coil 11a. Washing and drying apparatus is employed in connection with the pickling apparatus, but has been omitted from the Figure. The superposed layers then pass to edge welding rolls 9, further pinch rolls 12<SP>1</SP>, a heating chamber 14, Fig. 2, containing a neutral atmosphere and then to the reducing rolls 16 which effect a reduction in thickness of the composite strip of about 4 per cent and the bonding of the layers. A delivery passage 15 from the chamber 14 extends up to the rolls 16. The inner surfaces of the outer steel strips and both surfaces of the copper strips may, as another step in the process, be continuously and simultaneously cleaned by means of two endless cleaning and abrading belts. Edge welding of the strips may be dispensed with by using the apparatus illustrated in Fig. 7 in which the two outer steel strips are electrically heated by a current passing from rolls 24 to rolls 25 within a chamber 22 containing neutral gas and the superposed strips are further heated by elements 26 in the chamber outlet 15 on the way to the reducing and bonding rolls. The component strips are preferably introduced into the bonding pass at a temperature range of from 1650‹ to 2100‹ F.
