Title: Improvements in or relating to an automatically self-synchronizing spudding-mechanism for cable-tool drills
IPC: E21B1/02
Filed: 1954-09-02
Abstract: 757,009. Earth-boring apparatus. RUSTON-BUCYRUS, Ltd. Sept. 2, 1954 [Feb. 8, 1954], No. 25538/54. Class 85 The spudding mechanism of a cable-tool drill is actuated by a single-acting pistoncylinder unit to which pressurized fluid is supplied from a pump 21 through pipe 22, a by-pass in the casing of valve 23, and a pipe 24 and exhausted through pipe 24, valve 23. and pipe 28. The valve is controlled by the pressure in a second fluid system and a spring. When no fluid pressure is exerted on the plunger 25 of the valve 23, a spring maintains the plunger in such a position that the port 26 is open and fluid from the pump 21 by-passes the piston-cylinder unit 17 and is exhausted. The second fluid system contains a valve 38 the position of which is altered mechanically by means 51-54 just before the end of the down stroke to supply pressurized fluid from pump 31 via 'pipe 37, a by-pass in the casing of valve 36 and pipes 39, 40, 42 to act on plunger 25 to close valve 23 and cause pressurized fluid to be supplied to unit 17 to raise the bit 16 and, just before the end of the .upstroke, to shut off the pipe 39 and exhaust the pressurized fluid acting on the plunger through pipe 43 so causing the valve 23 to open and permit descent of the bit. The opening of the valve is retarded by a throttle valve 41 and the rate of descent of the bit is retarted by a plunger 29 controlling the rate of discharge through the port 26 of the valve 23. The operation of the plunger 29 is controlled by the pressure in the second fluid system in which there is also incorporated a stop-start valve 33 and a relief valve 46.

Title: Improvements in or relating to apparatus for determining the germination capacity ofseeds
IPC: A01C1/02
Filed: 1957-08-19
Abstract: 841,900. Testing seeds and grain. FOSS ELECTRIC A. S., N. Aug. 19, 1957 [Aug. 24, 1956], No. 26053/57. Class 58. In testing the germinating ability of seeds, particularly cereal grains, by treating them, under reduced pressure, with a liquid reagent, e.g. an aqueous 2% solution of 2, 3, 5-triphenyl tetrazolium chloride, which reacts with the seeds and develops a contrast in colour between embryos that are capable and those that are incapable of germination, the seeds are split into halves, substantially through their embryos, and placed in a vessel b. This is sealed by a cover h and evacuated, through a pipe I and valve f, by a suction pump e. Liquid reagent from a closed storage vessel a is sucked into the vessel b through a pipe c, a valve n, and a heated coil d. When the split seeds are covered with liquid reagent, the valve n is closed and the development of colour is allowed to proceed to completion, e.g. for 5 to 10 minutes at a pressure of 0À1 atmosphere and a temperature of 45‹C. The suction pump is then stopped, air is admitted to the vessel b through the valve f. A valve p in a pipe k connecting the vessel b with the vessel a is opened so that the liquid reagent is sucked back into the latter. The valves n and p may be squeeze valves having, respectively, squeezers s and s1, which are operated manually by an eccentric x. The squeezers s1 may be retained in a valve-closing position by a pawl o, which may be released by clock-mechanism u controlled, through the pipes I and r and a valve g, by the pressure in the vessel b. The valve g may be used, instead of the valve f, to admit air into the vessel b.
