Title: Improvements in or relating to clock-controlled electric switch gear
IPC: G04C23/16
Filed: 1946-06-06
Abstract: 614,949. Time-switches. SMITH & SONS (ENGLAND), Ltd., S., and ELLIS, J. W. June 6, 1946, No. 17254. [Class 38 (v)] A time-switch suitable for controlling a radio set, comprises a cam-member 18 attached to a spindle 17 which is rotatable by a 24-hour pinion 20 and is axially movable in a bush 11 carried by a plate 10 fixed to the switch frame, the cam-member 18 co-operating with setting- discs 12, 24 by means which impart rapid opening and closing movements to contactarms 34, 35. The disc 12 is fixed to the bush 11 and the whole is adjustably held against the plate 10 by a friction-washer 13 and spring- washer 15, being adjustable to vary the switching-on time, by a pinion 8 on an operating spindle 7. The cam 18 has a rim 22, notched at 19, which co-operates with a lug 23 pressed out of the disc 12, the notch 19 being so shaped that the lug 23 moves rapidly into, but slowly out of, it. The disc 24 is fixed to a bush 30, and is connected to the disc 12 so as to be rotatable therewith, but axially - movable thereto, by a lug 26 on the disc 12 which engages a slot 27 in the rim 25 of the disc 24. The disc 24 and cam 18 are urged towards the disc 12 by a forked blade spring 31, and a lug 28 pressed out of the disc 24 bears on the cam 18, being so shaped as to snap into and move slowly out of a slot 29 in the cam-face. The contact-arms 34, 35 are normally held apart by a fixed stop 42 and the spindle 17, but when, after a predetermined rotation of the cam 18, the notch 19 coincides with the lug 23, the disc 24 and cam 18 are suddenly moved axially by the spring 31 and the contact-arm 35 is snapped-over by a tension-spring 39 to engage the arm 34, which remains stationary due to a slot 36 in the bush 30 which it engages. Further rotation of the cam 18 brings the slot 29 opposite the lug 28, so as to impart further axial movement to the disc 24 and snap the arm 34 away from the arm 35. The switch parts are restored to their initial positions by continued rotation of the cam. A 24-hour indicating scale 16 is frictionally mounted on the bush 11, so that the switch may be set to close at a predetermined time, and a.m. and p.m. indications are provided by a disc 54 driven by a 24-hour wheel 53. In Figs. 6-8 (not shown), the setting-disc 24 is also adjustable and is geared to an indicating-disc showing the time the contacts are required to open. In a modification, separate switches may be controlled by the axial movements of the cam 18 and setting-disc 24.

Title: Improvements in or relating to the operation of a furnace
IPC: F23H11/00
Filed: 1947-07-01
Abstract: 658,739. Furnaces. COMBUSTION ENGINEERING-SUPERHEATER. Inc. July 1, 1947, No. 17288. Convention date, July 13, 1946. [Class 51(i)] A method for disposing of combustible matter in furnace fly ash in a furnace having a travelling grate over a substantial portion of the area of which fuel is spread from the furnace-leaving grate end for burning in a fuel bed upon the grate comprises the steps of introducing fly ash, containing combustible matter, from the furnace into the upper portion of the moving fuel bed near the furnace-entering end of 'said travelling grate and outside the main burning area from which the fuel combustion gases rapidly rise but at a location where the fuel is deposited upon the grate surface, advancing said thus-introduced fly ash across the furnace toward the travelling grate's opposite or furnaceleaving end along with the grate-carried bed of burning fuel and fuel ash while continuously adding new fuel thereupon, thereby covering said fly ash, usefully burning the combustible matter of said fly ash while that ash thus moves across the furnace in said bed, and discharging from the furnace at the travelling grate's said opposite end the unburnable fly ash residue along with the main ash from the burning fuel. Fly ash, separated at 34 from the combustion gases from a furnace 10 and collected in a hopper 36, is fed by rotary valve means 37 to a conduit 38 where a fluid, e.g. air or gas, flowing therethrough, conveys it through a series of distributing pipes 43, spaced across and above the furnace-entering end of a travelling grate 19, to the upper part of the fuel bed. outside the main burning zone. Here it is mixed with fuel projected over the length of the grate by a spreader stoker 15 at the furnace-leaving end thereof, the air flow up through the grate being reduced at the position below the fly ash distributers 43. The fly ash may be conveyed to the furnace by a screw conveyer or other means. Coarser fly ash separated out from the. combustion gases into a pit 33 may be removed therefrom and injected into the furnace either through the conduit 38 or at a point spaced above the trajectory of the projected fuel. The Specification as open to inspection under Sect. 91 comprises also the arrangement whereby the grate moves from front to rear of the. furnace and the fly ash is introduced at the end beneath the spreader. This subject-matter does not appear in the Specification, as. accepted.

Title: Improvements in reheat control systems for gas turbine engines
Inventor: GREENLAND LEONARD SIDNEY
IPC: F02K3/10
Filed: 1956-06-06
Abstract: 833,497. Gas-turbine Jet-propulsion plant. HOBSON Ltd., H. M. Aug. 27, 1957 [June 6, 1956], No. 17511/56. Class 110 (3). [Also in Group XXIX] A reheat fuel system for an aircraft gas-turbine engine in which air from the compressor associated with the engine is supplied to a turbine driving a pump supplying fuel to the reheat burners, has the air supply to the turbine controlled by a normally closed shut off valve actuated by a pressure-sensitive device connected by a conduit containing a bleed valve to the compressor delivery; the bleed valve is closed by means operable by the pilot to cause the pressure-sensitive device to open the shut off valve. A pilot's control lever 10 controls, in the zone A, the fuel supply to the main burners of the engine. On release of the catch 11 the lever 10 can be moved into the reheat zone B to cause fuel to be supplied to the reheat burners by a pump 12. The pump 12 is driven by an air turbine 14 supplied with air from the engine compressor delivery through a conduit 15 by opening a valve 16 normally held closed by a spring 18 acting on a diaphragm 17. Compressed-air is supplied to the underside of the diaphragm 17 by a conduit 19. This air is prevented from opening the valve 16 by a normally open bleed valve 20. When lever 10 moves into zone B a switch 24 is closed and a solenoid 25 energized. The armature 22 is retracted and the spring 21 closes the valve 20. Fuel compressor discharge pressure then acts on the diaphragm 17 to open the valve 16. As soon as the lever 10 is moved back into zone A the solenoid 25 is de-energized, the bleed valve 20 opens and the spring 18 returns the valve 16 to the closed position. The valve 16 may be closed by opening of the bleed valve 28 by the overspeed governor 26. In a modification, Fig. 2 (not shown), a shut-off valve mechanically linked to the lever 10 is provided at the inlet to the air turbine. This valve is open when the lever 10 is moved into the zone B. In this case the bleed valve 20 is operated by a cam also mechanically linked to the lever 10. A solenoid energized by a push-button may be provided to open valve 20 if the linkage fails. Specification 833,493 is referred to.

Abstract: 762,807. Photographic processing apparatus. COPYCAT, Ltd., [formerly COPYCAT ASSOCIATED (MARKETING), Ltd.]. Aug. 19, 1955 [June . 16, 1954], No. 17686/54. Class 98(2) Apparatus for processing sheets of photographic material comprises at least two shallow trays for processing liquids, spaced horizontally apart, receivers for liquid overflowing from each of the trays, pumps to return liquid from the receivers to the respective trays and means for feeding and guiding sheets through the processing liquids in the trays in succession. As shown, shallow trays 5, 6 containing processing liquids are positioned above receiving tanks 11, 12 which contain a reservoir of the respective liquids to a level 14. Pumps 15 situated in the tanks draw liquid from the tanks and pump it through pipes 17 to nozzles 18 in the bottoms of the respctive trays, from whence it overflows back into the tanks. Pairs of rollers 1, 2, 3, 4 are arranged to feed sheets, inserted at 50, through the apparatus and deliver them at 51. The sheets are guided through the liquids by curved guides 19, 20 the bottoms of which, dip into the liquids and define a narrow passage with the bottoms of the trays. The bottoms of the trays and guides are ribbed. The last pair of rollers 4 removes excess liquid from the sheets and delivers them partially dry, but these rollers may be omitted. Provision is made at 52 for inserting a sheet directly between rollers 2 so that it passes only through the second tray. The bottom rollers of each pair are driven at the same speed by a motor which also drives the pumps. The pumps are preferably arranged to deliver liquid intermittently to the trays so that a pulsating flow is obtained.

Filed: 1966-04-25
Abstract: 1,141,901. Welding by pressure; making bearing rings. TORRINGTON MFG. CO. 25 April, 1966 [22 July, 1965], No. 17898/66. Headings B3A and B3R. A method of making welded articles, particularly bearing races, formed at least in part from high carbon steel of carbon content exceeding 0À4%, comprises the steps of arranging end portions in closely adjoining relationship, electrically preheating the articles) while maintaining the ends relatively cool, urging the ends together and resistance welding them together, the welding step being commenced within one second of termination of the preheating step, and the heating and welding processes being carried out so that the temperature of the whole article is raised above the level at which austenite transforms to martensite and so that the formation of localized areas of martensite is prevented. Bearing races are formed by the steps of severing a suitable blank from strip material, forming the strip into an open hoop and chamfering the ends 18, 20 of the strip, applying an electric current to the open blank which flowing round the hoop and not through the weld areas raises the temperature of the body of the article to a level preferably about 100‹ F. above the upper transformation temperature, urging the ends together to effect a resistance weld and cooling the article by air cooling or quenching. The invention is applicable to lap or spot welds of articles other than closed loop articles.

Abstract: 1,156,216. Valves; one-revolution clutches. M. SIMONICH. 19 April, 1967, No. 17916/67. Headings F2C, F2L and F2V. [Also in Division G4] In an ice-cream dispensing device, insertion of a coin into coin-receiver 41 energizes an electromagnet 39 to retract a latch rod 40 to allow bar 33 to be pushed to the right. Tooth 35 on bar 33 moves lever 29 about its pivot 28 to disengage a cam 30 from a roller 27. This allows block 14 slidable in a diametral dovetail groove in flange 11 of sleeve 12 to be biased downwards by spring 18. The end 15 of block 14 enters one of a number of recesses 25 in an annular toothed flange 5 integral with a sleeve 6 which surrounds sleeve 12 within hub 7. Flange 5 is constantly rotated by motor 10 via pinion 9 and block 14 now transmits this rotation to flange 11. The latter is fast with a collar 19 having an eccentric roller 21 which co-operates with yoke 23 to open and close valve 2. After the flange 11 has completed one revolution, the roller rides up cam 30, which was returned with lever 29 by spring 31 after tooth 35 cleared the end of lever 29, and block 14 is raised to uncouple flanges 5, 11.

Title: Remote control manipulator
IPC: B25J3/04
Filed: 1965-04-28
Abstract: 1,092,950. Manipulators. PROGRAMMED & REMOTE SYSTEMS CORPORATION. April 28, 1965 [April 28, 1964], No. 17934/65. Heading B4Q. The control of a slave manipulator 17 similar to that disclosed in Specifications 1,019,989 and 1,021,304 is simplified by providing a master unit 16 which may be switched in circuit to take the place of certain controls provided in the console 51 of the aforementioned earlier Specifications. The unit 16 has arms 84, 96, 114 corresponding to slave arms 38, 40, 43, the arm 114 having a handle member 54 for engagement by the human hand. When the member 54 is engaged by the hand a pistol grip element 162 (Fig. 9, not shown) thereon may be operated to control an electric relay thereby enabling the unit 16 to take the place of certain controls of the console 51. The arms 84, 96, 114 are connected to a housing 76 fixed to a column 73 mounted at one end of an arm 71 pivotal about a vertical axis 172 on a carriage 60, this pivotal movement corresponding to movement of the slave arm about its vertical axis in the carriage 21. Movement of the arms 38, 40, 43 about the axes 36, 41, 44 is controlled by individual electric motors mounted in the shoulder 34, a further motor being provided for rotating the shoulder about the vertical axis. The three motors controlling the arms 38, 40, 43 have their counterparts provided in the master unit 16 by three tachometer generators mounted in the housing 76 and providing signals corresponding to movement of the arms 84, 96, 114 by the operator. A further tachometer generator in the carriage 60 corresponds to the motor driving the shoulder 34 and produces a signal when the column 73 is rotated about the axis 172. The signals generated by the tachometer generator are proportional to the angle of movement of the master unit component and the speed and the time of such movement and are supplied through an adjustable gain feed 181 to a preamplifier and direction relay control unit 182 (Fig. 12, not shown). The output from unit 182 controls a power centre 187 supplying the slave arm motors, the gain 181 being adjusted so that the slave component moves through the same angle in the same time as the corresponding component of the master unit. Rotation of the slave hand member 48 about the axis 49 is controlled by similarly rotating the handle member 54, movement of the member 54 operating a potentiometer controlling the motor driving the member 48. A trigger 164 on the handle member 54 (Fig. 9, not shown) operates a potentiometer controlling the motor driving the slave jaws 50 through an electromagnetic clutch, the further the movement of the trigger the greater the gripping force applied to the jaws through the clutch. The remaining movements of the manipulator are controlled as in the aforementioned earlier Specifications from the console 51.

Abstract: 145,698. Balslev, J. V., and Thode, A. Dec. 15, 1917, [Convention date]. Automatic circuit-breakers; sparking, preventing.-Consists in a spring-operated knife switch for tramcar and other use provided with an adjustable maximum-current electro-magnetic cutout device and a magnetic blow-out. The knife switch 6 is held closed against the action of a spring (not shown) by a pivoted locking-hook 9, and its contacts 7 are situated in the interpolar gap 35 of a magnetic yoke 2 which surrounds the coil 1 carrying the current to be broken. The gap is defined by an iron plate 4 at the lower end of the coil and an iron bed-plate 3. The core 14 is non- rotatably guided in brass bushes 12, 13 so as to slide through an iron ring 11 forming part of the yoke, and it is carried on a rod 15 suspended from a cross-head 21 pivoted on a lever 17 which is counterweighted at 27. The lever is pivoted at 18 on a fixed plate 20 and by means of a spring 32 and screw 33 any desired upward pull may be given to the core. Pivoted on the other end of the lever is the weight 27 which loosely encloses a rod 28 pivoted in the locking-hook 9 and guided by a bracket 29. The weight rests on a stop 31 on the rod, When the current reaches a limiting value, descent of the core lifts the weight sharply against the adjustable stop 30 and raises the hook, allowing the switch 6 to open. Descent of the core meanwhile shortens the gap 34 and gives a strong blow-out field. By turning the screwed rod 15, the core may be adjusted to control the limiting current without altering the setting of the spring 32 or the length of stroke which is limited to a constant value by the abutment of the rod 15 on the plate 4.
