Title: Discharge regulator for petroleum separators
IPC: F16K31/34
Filed: 1939-05-11
Abstract: 528,649. Float-actuated valves. GERDTS, G. F. May 11, 1939, No. 14063. Convention date, Aug. 23, 1938. [Class 135] A discharge regulator for petroleum separators comprises a discharge valve i having two co-axial conical lift valves k, l seating one upon the other, the smaller valve k being opened at a relatively low liquid level in the separator a whilst the opening of the large valve l is delayed until the cylindrical float b which actuates the valves is so far immersed that its buoyancy raises the valve k against an adjustable screw o carried on a part p connected to the larger valve. The larger valve cone l and if desired the smaller valve cone k also, is loaded by weights. The seat of the larger valve is chamfered at w to provide a large outflow space so that no substantial balancing pressure is produced in the outlet when the valve k is open. The float b has tapered ends c, d to prevent the accumulation of impurities e.g. sand thereon, and is guided by a link e. The movement of the float is transmitted by a linkage f, g, h part of which is housed in a tube s to avoid the use of stuffing boxes. A metering device q is arranged in an arcuate pipe r connecting the discharge valve i and the separator.

Filed: 1973-03-23
Abstract: 1410836 Spark gaps M-O VALVE CO Ltd 21 March 1974 [23 March 1973] 14137/73 Heading H1D A spark-gap arrestor comprises metal endcaps 1, 2, a metal central tube 3 and ceramic parts 4, 5, assembled to make up a gas-tight cylinder. Electrodes 6, 7 are brazed to the end caps, and electrode 6 has an opening, subsequently sealed at 10, for filling the arrestor with gas. In use, the end caps 1, 2 are connected respectively to two lines of an electrical supply, and the central tube 3 is earthed. When overvoltage occurs between the lines or between a line and earth, a spark gap breaks down. Since the arrester may fail without giving any indication, there is provided at each end a pair of ring-shaped members 13, made of a fusible material, (e.g. an alloy of 3 parts Su and 2 parts Pb) and shouldered at 14 to support a ceramic cylindrical spacer 15. These parts are covered by a sleeve 16 made of a material which shrinks when heated. If the arrestor is overheated, a hole may form in the tube 3 so that the gas escapes and the device cannot conduct. Before this can occur, the members 13 melt. Sleeves 16 contract so as to cause the molten material to flow between the end cap 1 or 2 and the central tube 3, so that one of the lines is earthed.
