Title: Improvements relating to condensing steam plant and control systems therefor
IPC: F01D17/14
Filed: 1929-05-30
Abstract: 334,245. Blacklock, T., Walker, G. W. Higgs-, and Associated Electrical Industries, Ltd. May 30, 1929. Stop-gear.-In plants in which steam exhausted from one prime mover is delivered to a second prime mover or directly to a condenser, the valves controlling the condenser connection and the turbine connection are operated by fluid relays controlled by a common valve so that the condenser valve is opened before the turbine valve is shut, or the turbine valve is opened before the condenser valve is closed. When fluidpressure controlled by a cock 12 is admitted to a pipe 11 leading to a relay of the kind described in Specification 334,244, [Class 122 (iii), Steam engines, Kinds &c.], the relay valve 10 is raised and pressure fluid is supplied by a pipe 18 to the lower side of the piston 7 and the condenser valve 5 is closed. Similarly the turbine valve 2 is held in the open position. The supply pipe of the turbine valve relay is connected to the pipe 11 by a poppet valve 29 which is opened by excess pressure in pipe 11 and through a tappet 30 by a lever 31 connected to the rod 8 of valve 5 is partly opened. If the exhaust turbine is to be shut off and the exhaust bye-passed to the condenser, the valve 12 is turned through 90‹ to open the drain 14, the valve 10 is pressed down by the spring 15, and the two sides of the piston are connected to the outlet 20 when the valve 5 is opened by the action of the spring 9 or by the weight of the parts. When the valve is partly open, valve 29 is raised to connect the pipe 28 to the drain 14 and allow valve 27 and piston 24 to descend to close the valve 2. The valve 8 is thereby opened before the valve 2 is closed. The springs 9, 25 are chosen so that the valve 2 is opened before the valve 5 is closed. Relief-valve means may be provided to permit the valve 5 to open should the pressure in the trunk exceed a predetermined value. An overspeed governor or other emergency device may operate the valve 12. Specification 334,244, [Class 122 (iii), Steam engines, Kinds &c.], is referred to.

Patent GB-651668-A (GB)
Title: Improved process for the production and purification of sulfur hexafluoride
IPC: C01B17/45
Filed: 1948-06-24
Abstract: Sulphur hexafluoride is made by maintaining a body of molten sulphur, directing a stream of fluorine gas to impinge upon the surface of the sulphur, regulating the flow of fluorine to supply not more than one pound per hour of fluorine for every 20 square inches of surface of molten sulphur and withdrawing the gaseous reaction products.  The sulphur level may be maintained by supplying sulphur to the molten sulphur, e.g. through a liquid sulphur seal, and the fluorine may be supplied through a jet located from 1 to 6 inches above the surface of the molten sulphur.  Crude sulphur hexafluoride, containing as impurities acidic gases such as fluorine and/or hydrogen fluoride and S2F10 with or without lower sulphur fluorides, is purified by washing with an aqueous liquor, which may contain up to 50 per cent by weight of an alkali such as sodium or potassium hydroxide, sodium carbonate or calcium hydroxide, heating the washed gas to at least 250 DEG  C., e.g. by passing it through a decomposer comprising a copper tube packed with carbon or bauxite and heated electrically to 250-400 DEG C., and again washing with the aqueous liquor.  The gas may be stored in this condition over water or it may be dried, e.g. by sulphuric acid or refrigeration or by washing with 96-98 per cent sulphuric acid and passing through a bed of activated alumina, and condensed directly as a solid or a liquid into pressure cylinders.

Title: Improvements in and relating to the control of aircraft
IPC: B64C1/00
Filed: 1919-07-09
Abstract: 152,125. Marshall, R. July 9, 1919. Steering, balancing, and regulating altitude.- In operating means for the control members of aircraft having pendulum or gyroscopic correction, the controls are given a hand setting combined with means for automatically correcting deviation from the set course. A double piston valve 6, 7 in a valve chamber 1 controls the admission of fluid pressure to an engine 5, which rocks a shaft 10 that moves the control member of the aircraft. The cylinder 1 and valve 6, 7 are attached to levers 8, 9, one of which is keyed to the shaft 10. On the pilot moving the loose lever and thus the cylinder or valve, a motion of the shaft and aircraft control member takes place, and the keyed lever brings the system back to neutral and serves to lock the controls. A similar valve 11 is in parallel arrangement with the first valve, a common supply pipe 13 being coupled to the parallel systems by a three-way cock 14. The valve 11 is mounted on links 12, and the valve rod is coupled by links with the bearings 17 of a gyroscope. In operation, the cock 14 opens up the valve system 1, and the control member is given any required movement. For further automatic course keeping. the valve 11 is similarly set by a lever 18, and the cock 14 cuts out the valve system 1 and opens up valve system 11. On any deviation taking place, relative movement of the casing and piston of the valve 11 operates the engine 5 and the aircraft control members to restore the craft to its course. The engines may be of the described in Specification 129,861.

Filed: 1954-06-11
Abstract: 760,754. Wire tensioning. VERRERIES DE LA GARE ET A. BELOTTE REUNIES., and CARLIER, D. June 11, 1954 [July 1, 1953], No. 17280/54. Class 45. [Also in Group XVII] In a packaging machine comprising two cradles 10, 11 holding the articles to be packaged and rotatable to wind spaced wires 27, 28 around the articles, each wire is tensioned by means of a guide pulley 42, Figs. 4, 6, mounted on a rocking lever 43, and a gripper 35 linked with the lever to be actuated by rotation of the cradles. The cradle 11, mounted on a shaft 17, is rotated by a handle 26 and bevel gears 24, 25, and the cradle 10 is connected by gears 19, 20, 22, 23 to rotate with the cradle 11 on a shaft 16. The wires 27, 28 from spools 31, 32 pass over the pulleys 42 and the articles in the cradles to be attached to the cradles at 29, 30. During the first part of the rotation of the cradles a cam 59 on the shaft 17 acts on a linkage to turn a shaft 44 so that levers 45 move from the position D to the position D<SP>1</SP>, Fig. 4. The levers 45 lift latches 75, mounted on the rocking levers 43, from stops 50 on axially slidable spring biased rods 38 connected to the grippers which are pivoted at 36. The adjustable end parts 69 of the rods are pressed by the springs against the levers 45, the clearance between the grippers and fixed members 33 being sufficient to permit the wires 27, 28 to be withdrawn from the spools. Towards the end of the cradle's rotation the cam causes the levers 45 to move to the position D, the rods being urged by the springs so that the wires are held between the members and the grippers. As the cradles complete a revolution the levers 43 rock about the shaft 44 and the wires are tightened about the articles, (Fig. 6). Tying and cutting devices 61, 62 sever the wires from the spools and permit the return of the rocking levers 43 to the position shown in Fig. 4. During the last movement of the rocking levers, the levers 45 are in the position D so that the latches 75 engage the stops 50 to move the rods and the grippers to release the wires. Specification 726,499, [Group XVII], is referred to.

Title: Improvements in or relating to electric control circuits
Inventor: COYLE PETER AUGUSTINE
IPC: G05D23/24
Filed: 1964-07-27
Abstract: 1,106,147. Automatic temperature control systems. PLESSEY CO. Ltd. July 16, 1965 [July 27, 1964], No. 17317/64. Addition to 892, 825. Heading G3R. The control circuit of the parent Specification is modified by replacing the on/off switch by a thyristor type continuously-variable regulator 4 whose firing angle is controlled by a phase shift network 6 and a phase discriminating rectifier 5, the latter being fed from the toroidal core error detector 3 responsive to the temperature of the heater element 1. To ensure that the error signal is dependent only upon the resistance of the heater 1, a sampling network 7 is arranged to control the member 5 so that the latter only produces an output when the heater resistance is at a voltage not variable in response to the firing angle of the regulator 4. This is done by limiting the output of member 5 to the last 45‹ of each half cycle of the supply 2 and by limiting the maximum firing angle of the regulator 4 to 120‹, this corresponding to minimum heater power. Member 7 comprises a thyristor phase shift regulator controlled by a firing circuit that can be preset to give a constant phase shift. Regulator 4 may be of thyratron or saturable reactor type.
