Patent GB-842975-A (GB)
Title: Method of and apparatus for flooding sample cores taken from oil-bearing rock strata
IPC: G01N33/24
Filed: 1956-06-06
Abstract: 842,975. Testing oil-bearing rock samples. DEUTSCHE ERDOL A.G. June 6, 1956 [June 7, 1955], No. 17549/56. Class 106 (2). [Also in Group XXIX] A method of flooding sample cores taken from oil-bearing rock strata to ascertain the extent to which oil can be removed by forcing water into the strata, comprises enclosing a sample core 2, Fig. 1, in a soft metal casing' 2a, placing the filled casing in a medium 1a that is maintained at a higher pressure than the flooding pressure, reproducing the pressure and temperature of the rock strata in the sample core 2 and in the medium 1a, and then flooding the core to expel the oil from it. The expelled oil is collected in a measuring-apparatus 23, having means 22 for separating the liquid and gaseous constituents from one another, the gases being sucked into collecting means 25, 27, 29, through a pressure-regulator 24 (see Group XXIX) maintaining a constant pressure in the separator 22. The core 2 in its casing 2a is initially filled with salt water and the volume of its pores determined by the amount of liquid absorbed. The sample in its casing is then placed in the chamber 1 to which oil under pressure is supplied by a pump 3. The chamber 1 is surrounded by a jacket 1b through which a heated liquid flows. By opening suitable valves, compressed air from a bottle 16, or compressed mineral oil from a pump 17, is used to cause crude oil in a container 8 to flow through the core sample to expel the water therein. When oil begins to emerge from the sample via a pipe 6, the container 8 is shut off and a vessel 10 containing water from the strata is used to expel the oil in the sample to the receiver 23 via the separator 22. To collect the gases in the separator 22, a levelling vessel 26 is lowered to create a subatmospheric pressure in a measuring tube 25 coupled to the separator 22 through the pressure-regulator 24. As soon as gas is released by the oil an almost inappreciable superatmospheric pressure is produced which suffices to operate the regulator 24 so that gas flows from the separator 22 to the measuring tube 25. When the tube 25 is filled it is shut off and the levelling vessel 28 and measuring tube 27 is connected to the system. By raising the levelling vessel 26 the gas in the tube 25 is passed to a collecting-tube 29. As soon as water drops appear at the outlet side of a regulator valve 21 the receiver 23 is removed. A differential pressure-measuring device 31 is connected across the rock core. Core casing. The soft metal casing 2a, Fig. 2, may be an easily fusible alloy of bismuth and tin, the casing terminating in brass rings f and end caps 2b formed with conduits.

Mines, marine.-Relates to submarine mines automatically moored at a given depth by means of a plummet, which on touching bottom causes a bell crank to lock a mooring cable drum in a sinker. According to the invention, a downwardly extending arm f of the bell crank f, d carries a hinged toe-piece w, controlled by a spring x, and is connected by a link g to a quadrant h carrying a sheave m over which the plummet line k is reaved. The plummet line also passes over another pulley on the sinker; and the plummet l is held in brackets o, o and against a stirrup p by a catch q, which is locked by the hooked end r of a lever s connected to a rod t carrying a roller u confined by a guideway on the launching apparatus. When the mine is launched and the roller rides off the guideway, a spring v moves the rod t down and removes the hook r from the catch q; the plummet falls, and the pull of its line draws the toe-piece w away from a slide y; the toe-piece springs up and the bell crank is then free to swing back to lock the mooring cable drum b when the plummet touches bottom. The slide y is for releasing the mine from the sinker in recovering operations.

Abstract: 745,903. Fluid-pressure servomotor-control systems; fluids, regulating volume of flow. FOXBORO CO. July 17, 1952 [July 20. 1951], No. 18116/52. Class 135. In order to reduce transfer lag in a pneumatic transmission system consisting of a measuring element at one end of a single transmission pipe and a control, recording, or indicating instrument at the other end, a compact apparatus having an impedance substantially equal to that of the transmission pipe is included, the apparatus comprising a first pneumatic feed-back device providing a proportional control action, and a second pneumatic feedback device including a resistance or a combined resistance and capacity. In an embodiment, the pressures on the two sides of an orifice plate in a flow line are applied differentially to a diaphragm 16, and any resultant movement thereof is applied through a cantilever 19 to act on a spring-hinged arm 22. The latter acts adjustably on a spring baffle plate 25 controlling the discharge of pressure air from a nozzle 26, the latter being supplied from a pipe 32 past a restriction 33. The control pressure so produced upstream of the nozzle acts on a diaphragm 31 to position inter-connected inlet and exhaust valves 35 of a volume amplifier controlling the connection of the pressure supply 32 to a pipe 34. The output pressure in pipe 34 is transmitted through a line 12 to operate, in this case, an indicator 13. The output pressure supplied to the indicator is made proportional to the input signal applied to arm 22 by feeding the output pressure to a bellows 39 acting on arm 22 in opposition to the input signal. The transfer lag in line 12 is neutralized by combining an initial amplified surge with the output signal, and this is obtained by a further feedback of the output signal to arm 22, but this time the feed-back is through a resistance 38 and into a capacity constituted by a bellows 40. The transfer lag of the resistance-capacity combination approximates to that of the line 12. The resistance and capacity may be split into several units in series, and the resistances may be variable and each may be similar to the resistance disclosed in Specification 670,419. In an alternative arrangement, the two feed-back bellows are applied to a baffle and nozzle relay at the receiving end of the line 12. Specification 672,879 is referred to.
