Filed: 1918-11-11
Abstract: 123,038. Walker, H. C. Nov. 11, 1918. Systems controlling travel for a fixed distance.- In a controller for electric motors which is operated by the driven parts, mechanical means are provided for disengaging the operating-means at the end of the travel of the resistance arm, and are operated by the driven parts. The resistancecontrolling arm h is carried by a pivot h<1>, and its movement is controlled by the dash-pot t<1>. The segmental gear carried by the arm h is engaged by a pinion g on a bell-crank lever g<1> when the main motor switch j is closed. The controlled motor b drives a worm b<1> which rotates a wheel b<2> attached to a spur-wheel c normally meshing with a wheel d. The sprocket-wheel e attached to the wheel d is connected to the wheel f by a cha.in. The worm b<1> and wheels b<2>, c are carried by a bar p supported in a sleeve, n by a spring o and held down in the position shown by a detent q. When the switch j is closed, the motor starts and operates the resistance arm through the gearing. As the arm h approaches the end of its travel, it engages the sleeve n and compresses the spring o. At the end of the travel, the latch q is released by the arm h, and the spring o raises the rod p, thereby disengaging the wheels c from the wheel d. A finger u on the bar p engages the teeth of the wheel d and holds the resistance switch in the full on ' position. When the current is cut off, the pinion g is disengaged from the rack, and the arm h falls to reinsert the starting-resistance. The pinion g may be operated bv the cores of the reversing switch of a lift controller, in which case two racks are necessary. Specification 15933/11 is referred to.

Abstract: 775,979. Casting-machines. IMPERIAL CHEMICAL INDUSTRIES, Ltd., and ATTKINS, R. July 2, 1954 [July 3, 1953], No. 18467/53. Class 83 (1). [Also in Group XI] In melting reactive metals of high melting point such as titanium, zirconium, thorium, hafnium, molybdenum, tantalum, chromium and their alloys by an arc between electrodes 7 and the surface of the metal 13 to be melted in a water-cooled metal crucible 1, the electrodes 7 are mounted radially in the side of the crucible or of the furnace lid, and the watercooled base 11 of the crucible is longitudinally adjustable, so that as an ingot is built on the base 11 the base is gradually lowered and the arc is maintained. The water-cooled electrodes 7, which are transversely adjustable and may be moved over the melt during operation, are shown mounted in a flange 6 of the water-cooled furnace lid 3. Raw metal is fed through a tube 5 in the lid 3, which has sight-glasses and means for supplying argon or helium or for a vacuum connection. A sealing ring 4 provides a vacuum seal between the crucible and the flange 6 of the lid, which may carry six electrodes. The crucible base 11 is mounted on an hydraulic jack, and has a spring-loaded sealing ring 12 to conform to the outward downward taper of the crucible wall, which facilitates extraction of the ingot. A preformed disc 13 of the metal may be secured by dovetailed keying on to the base 11, which is moved towards the electrode 14 for starting the arc. After removal from the furnace, the bottom end of the ingot may be sawn off and re-used for starting the arc. Continuous casting may be effected by providing a flying saw beneath the crucible to cut the ingot into required lengths, and by providing withdrawal rolls or the like to control movement of the emergent ingot when the crucible base is removed.

Title: Acceleration control of gas turbines
IPC: G05D23/12
Filed: 1957-06-12
Abstract: 862,962. Gas turbine plant. SOLAR AIRCRAFT CO. April 17, 1958 [June 12, 1957], No. 18558/57. Class 110 (3). An acceleration control tor a gas turbine comprises valve means to meter the fuel to the turbine means responsive to the compressor delivering pressure connected mechanically and tending to open the valve means and means responsive to the fuel pressure at the outlet of the valve means connected mechanically and tending to close the valve means. Fuel from a manifold 10 is led through a filter 16 to a shut-off valve 20 forming part of a fuel pump 22 and which is closed if the turbine overspeeds by approximately 8%. The valve 20 is connected by a conduit 24 to an accumulator 28 which is in turn connected to the fuel pump 22. The fuel pump discharge is connected to the accumulator 28 and discharges through flyball governor 36 to a four-way manually operated control valve 40. The control valve 40 is connected to an acceleration control 56 and the burners 70. The turbine is cranked with the control valve 40 in the " off position, Fig. 2. The pump 22 which is driven by the engine supplies fuel to the closed valve 40. During this period, fuel is pumped into the accumulator 28. The operator then moves the handle 60 to the " ignite " position. This allows fuel to pass through line 42 to the burner 70 which is then ignited by a spark plug. The handle 60 is then moved to the " accelerate " position in which fuel is supplied through conduit 52 to the acceleration control 56 where it is metered and then passed to the burner 70. At the design speed where the flyball governor 36 exerts control, the valve 40 is moved to the " run position and the acceleration control 56 is by-passed.. The acceleration control 56 comprises a body 200 containing a pressure bellows assembly 275 and an aluminium piston 238. The piston 238 has holes 246 which co-operate with a groove 236 of a sleeve 222 to regulate the fuel flow from an inlet 220 to an outlet 264. The piston is controlled by the compressor discharge pressure acting inside the bellows assembly 275 which tends to open the holes 246 against the action of a spring 240 and the fuel pressure at the outlet acting on the wall 247. A seal assembly 263 is provided to prevent leakage of fuel into the housing 200. A screw 302 acting on a member 298 allows the loading of the spring 240 to be adjusted. Modified forms of acceleration control in which the bellows 275 are replaced by a diaphragm are also described.

Patent GB-357187-A (GB)
Title: Improvements in or relating to recording devices for coke-ovens
IPC: G07C3/12
Filed: 1930-06-18
Abstract: 357,187. Charging and discharging coke ovens. WADE, H., 111, Hatton Garden, London.-(Koppers Akt.- Ges., H. ; 29, Moltkestrasse, Essen, Germany. ) June 18, 1930, No. 18862. [Class 51 (ii).] Indicators.-The successive discharging and charging operations of a coke-oven plant are recorded on a clock-driven drum by a device associated with the pusher mechanism as it is moved along a battery of ovens. The recording device is actuated by a cable or other flexible means extending alongside the battery of ovens and movable in accordance with the movements of the pusher and/or the leveller into and out of the ovens as well as with the movements of the pusher carriage. As shown in Figs. 1, 2 and 3, the pusher mechanism comprises a carriage 12 with wheels 13 movable along rails 14 in front of a battery of ovens 11. An endless cable 15 extends between an idler 16 and a driving roller 17 being guided over pulleys 18, 19 and an operating pulley 20. The pulley 20 is not rotated when the mechanism is displaced along the rails so that the movement of the cable is imparted to' the roller 17. This roller is connected by gearing to a bevel wheel 40, Fig. 5, in mesh with a bevel gear 41 on a screwed spindle 42, provided with a squared section 43 and a recording member 44 co-operating with a record strip on a clock-driven drum 45. The records of the movements of the pusher bar 22 and leveller bar 32 are superimposed on the record of the oven numbers by attaching cables 23, 33 to the bars. The cable 23 is given a turn around a guide pulley 24 and passes over guide pulleys 25, 27 to a counterweight 28. The pulley 25 is carried at one end of a counterweighted arm 26 secured to the pulley 20. As the bar 22 is pushed into the oven the slack of cable is taken up by the weight 28 until the point of attachment 21 comes over the pulley 24. As the movement proceeds the weight 28 will rise until a fixed stop is reached and further movement will cause a raising of the arm 26 to rotate the pulley 20 and thereby the cable 15 and roller 17. The cable 33, which is carried in a manner similar to that of the cable 23, passes round a pulley 35 on the other side of the arm 26 and imparts an oscillating movement to the arm 26 as the bar 32 is reciprocated in the oven. In addition to the record of the movement a record of the current required to operate the motor may be produced by connecting the movable element 47 of the circuit ammeter 46 to a link 48 carrying a stylus 49 adapted to produce a straight line record.

Title: Improved process for matting textiles
IPC: D06M15/423
Filed: 1937-07-06
Abstract: Textile materials are matted by treating in a bath in which a water-insoluble urea-formaldehyde condensate is caused to separate from an acid solution in a colloidal state, the condensate having been previously subjected to the action of water.  The preliminary treatment with water modifies the properties of the condensate and allows it to be dissolved in the acid bath under milder conditions. In examples: (1) a urea-formaldehyde condensate is dried, coarsely ground and heated at 120 DEG  C., finely ground, re-heated, stirred into water and allowed to soak overnight.  The swollen product is dissolved in dilute formic acid and added to a solution of common salt; viscose silk treated in this bath is matted; (2) a urea-formaldehyde condensate is heat-hardened, made into a fine paste with water and allowed to stand.  The paste is stirred into formic acid and added to a dilute solution of common salt to produce a white opalescent colloidal solution; the bath delustres dyed viscose. Specification 469,688 is referred to.
