Title: Steam-power installation for deep-boring operations
IPC: E21B3/06
Filed: 1936-05-28
Abstract: 459,643. Power-generating systems. SCHMIDT'SCHE HEISSDAMPF GES., 2, Rolandstrasse, Wilhelmsh÷he, Cassel, Germany. May 28, 1936, No. 15125. Convention date, May 28, 1935. [Class 122 (iii)] In a steam-power installation for deep-boring operations, the valve-gear control and the feed-pump control are mounted on the boring table so that the supervisor can adjust the valve gear and shut off the boiler feed to increase the power to withdraw the rod, and can start the feed at the end of the withdrawal operation. The exhaust from the steam-engine 4 passes to a feed-water heater 13 and then to a blast pipe 15 in the boiler uptake. The feed-water pump 16 is provided with a shut-off valve 18, and the water after passing through the heater 13 passes to the boiler drum 6. Main steam is branched by a pipe 20 from the main pipe 10 through a valve 21 to the engine exhaust pipe 12. The levers 25, 26 of the shut-off valves 18, 21 are actuated by a lever 22 rotatable about the axis 23 of the lever 7 which controls the engine valve-gear 9 and to which it may be connected during the withdrawing of the rod. When the engine is stopped, the feed-water valve is opened and the byepass valve 21 is opened to supply steam at reduced pressure to produce the blast to accelerate combustion. When the rod is lowered the lever 7 is uncoupled from the lever 22. The transmission may be effected through servomotors operated by air, water, or pressure oil.

Title: Improvements relating to flexible tubing
IPC: F16L11/115
Filed: 1955-03-08
Abstract: 800,372. Flexible hose. HOOVER, Ltd. March 8, 1955 [Oct. 4, 1954], No. 15667/56. Divided out of 800,371. Class 99(2). A method of making a flexible hose comprising a deeply corrugated tube 10 of thin thermoplastic elastomeric material and a resilient helical reinforcing coil includes, longitudinally extending the coil, expanding to a greater diameter than that of the coil, a tube of elastomeric material having a free diameter less than that of the coil and a free length substantially greater than the free length of the coil and fitting it over the coil when so extended, releasing the tube and the reinforcement to allow the tube to contract radially and the coil to contract longitudinally and heat treating the tube by heating it whilst so released and free from any substantial external force to soften and relax the tube and allow it to bulge between the convolutions of the coil in a deep helical corrugation and allowing it to cool to impart a permanent set to such corrugation. As shown the coil 11 is placed on a mandrel 20 and stretched lengthwise, Fig. 2, so that the length of the coil is from two to four times its free length. Air under pressure is supplied by a hose 22 to inflate the tube 10 and the pipe 21 is tilted so that the mandrel and coil slide into the tube 10. When the air is released the tube contracts round the reinforcement. After removal of the mandrel the assembly of the tube and coil is heat treated. Hot air may be supplied or the hose may be heat treated by immersion in a bath of hot water maintained at a temperature of from 150 to 180F. by a thermo-statically controlled heating element. If steel reinforcement is employed the ends of the hose may be plugged to prevent entry of water but if aluminium wire is used the water should be allowed to enter the hose to make it sink. The hose need only be immersed for a few seconds. The coil 11 is normally contracted longitudinally so that its coils are substantially in contact being separated only by the thickness of the walls of the tube 10. The wire may be of steel and the coating 13 and tube 10 of vinyl chloride. The steel wire may be replaced by aluminium or aluminium alloy wire. The coating 13 may be applied to the wire by extrusion before the wire is coiled. The wire is then wound in a pretensioned helical coil for example with the aid of a machine as described in Specification 673,043. Specific details of the sizes and strength of parts of the hose are quoted. Specifications 800,373 and 800,374 also are referred to.

Filed: 1954-05-27
Abstract: 753,082. Crimping fibres. INVENTA AKT. - GES. FUR FORSCHUNG UND PATENTVERWERTUNG. May 27, 1954 [May 28, 1953], No. 15722/54. Class 120 (3). [Also in Group XXXV] The degree of crimping of a tow or bundle of fibres within a mechanical pressure crimping device is regulated by continuously weighing a quantity of slack tow formed between the device and a following machine and using departures from a predetermined weight to regulate the crimping pressure; the ratio between the speed of the tow fed to the device and the draw-off speed of the following machine is adjusted to a predetermined value. As shown, a smooth uncrimped bundle or tow 1 is fed by rollers 2 into a chamber 3 and, as the pressure within the chamber overcomes the action of a spring 13 against a closure flap 12, crimped tow 4 emerges and falls into a vessel 5 to form a supply 6 which is then withdrawn by a cutting machine 7. The vessel 5 is carried on a weighing machine 8 having a pointer 9 moving over a scale 10 on which are adjustable tolerance marks 11; when the pointer 9 coincides with a mark 11, a servomotor 15 is operated, as by electrical or pneumatic means, and rotates through reduction gearing an adjusting screw 14 whereby the resistance of the flap 12 to the emergence of fibres from the chamber 3 is altered. A driven conveyer band mounted on the weighing machine may replace the vessel 5. A dial 16, which indicates the ratio of the speeds of the tow entering the crimping device and entering the machine 7, may comprise cross-coils in opposition, each connected to a current generator operated by rollers, as at 2 and 7.

Abstract: 1412074 Steam generation; feedwater supply NERATOOM NV 2 April 1973 [10 April 1972] 15734/73 Heading F4A A nuclear reactor plant comprises a first circuit 7 filled with a heat-transfer medium other than water, such as liquid sodium and including a nuclear reactor 1, a pump 8 and the primary section of a heat exchanger 10, a second circuit 11 filled with a heat transfer medium other than water and including the secondary section of the heat exchanger 10, the primary section of a steam generator and a pump 12, and a third circuit containing water/ steam and including the secondary section of the steam generator, a steam turbine 18 with a controllable shut-off valve 33, a condenser 20, condensate pump 21, a feedwater pump 22 and a feedwater conduit including a controllable valve 25 and being such that at full load there is a pressure difference between the ends of the conduit of at least 10 bars, and regulating means for controlling the mass flow in the first and second circuits in dependence as the quantity and/or pressure of steam supplied to the turbine. A separator 27 between evaporator 15 and superheater 14, which constitute the steam generator, passes steam to the superheater and returns liquid water to preheater 26. The water level in the separator is kept constant by valve 49, controlled by a level detector 49. If there is a drop in steam pressure, for example because of a greater flow through the turbine, then the resulting increase in feedwater flow caused by the pressure drop in the separator will be corrected by valve 25 increasing the pressure drop in the feedwater supply; valve 25 is controlled by flow sensor 46 in the return from the separator. The pressure drop across the valve is also used to control feedwater pump 22. Likewise the mass flow and the pressure in the steam circuit are used to control secondary circuit pump 12, and the mass flow in the secondary circuit to control the primary circuit pump 8 and the reactor control rods 3. Instead of the pressure drop in the feedwater supply being produced by throttling of the flow by valve 25, this may be achieved in a turbine (60), Fig. 2 (not shown) connected to the pump 22, the amount of feedwater passing through the turbine being determined by valve (59) controlled by the flow sensor 46.
