Title: Remote manipulating arrangement and device
IPC: B25J5/04
Filed: 1961-08-21
Abstract: 925,788. Handling radio-active material. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 21, 1961 [Aug. 19, 1960], No. 30074/61. Class 39 (4). A remote manipulating arrangement permitting several cells to be served by a single manipulator wherein the manipulator is carried by a carriage movable along guideways in a corridor with which the cells connect through openings, the manipulator being movable into a particular cell when the carriage is located in the corridor opposite to that cell. As shown in Fig. 1, a number of cells 2 . . . 6 in which nuclear material is to be treated open through sliding doors 2p . . . 6p into a corridor 1 provided with longitudinal guideways (Fig. 2, not shown), on which a gantry 9 may run through rollers 10. The gantry supports a structure 13 movable on the gantry transversely to the corridor axis, the structure 13 supporting a turret 22 by means of rollers 23 24 so that the turret may rotate about its vertical axis. Horizontal guideways 28, 29, 30 on the turret serve to carry a support 34, 39 for the manipulator M, Fig. 5, by means of rollers 35, 36, 37. One side wall 2a of each cell has three guideways 2c, 2d, 2e similarly placed to the guideways 28 . . . 30 whereby a manipulator may be rolled from the turret into a selected cell after opening the cell door. The cells 2, 3 and 4, 5 are arranged back-to-back, the walls 2a having the guideways being provided with observation ports 2b and the opposite walls 2f carrying apparatus to be handled by the manipulator. The alignment of the guideways 28 . . . 30 with the guideways 2c. . . 2e is performed by transverse movement of the structure 13 and rotational movement of the turret 22. The manipulator M comprises three telescopic elements 48, 48a and 48b, the latter carrying jaws, the manipulator being supported for movement about an axis y-y<SP>1</SP> in a yoke 44, this yoke being rotatable about an axis x-x<SP>1</SP> in a plate 41. The plate 41 is mounted for vertical movement in the support 34, 39. The various motions of the gantry, turret and manipulator are performed by electric motors mounted on those members, the supply being connected thereto by flexible cables. To enable the cell door to be closed after a manipulator has entered, the electric supply for the manipulator instead of being taken from the corridor 1 is taken from a socket outlet in the cell. To facilitate the changing of the electrical connections, the turret has further guideways 31, 32 normally supporting a junction box (Fig. 6, not shown), this box being transferable on to further horizontal guideways provided on the cell wall.

Patent GB-1471673-A (GB)
Title: Transistor amplifier arrangements including protective means
IPC: H02H3/38
Filed: 1974-07-09
Abstract: 1471673 Transistor amplifying protection circuits SONY CORP 9 July 1974 [12 July 1973] 30403/74 Heading H3T [Also in Division H2] In a protective arrangement for a transistor amplifier 3, a capacitor 12 is charged in accordance with the output current of the amplifier and discharged in accordance with the voltage across the load 7. On positive half cycles, the capacitor 12 is charged by diode rectifier 8 in series with resistor 9 by the voltage produced by the output current in resistor 6, whereas on negative half cycles diode rectifier 11 in series with resistor 10 comes into operation and discharges it in accordance with the voltage across loud-speaker 7. At initial switch on, transistor 13 is non-conductive, and consequently transistor 14 is non-conductive. Capacitor 16 is not charged, so that transistor 23 is non-conductive. The base of transistor 29 is then biased positively from terminal 5, and its collector to emitter path is conductive to shunt the input to amplifier 3. Capacitor 16 charges through resistor 22 and renders transistor 23 conductive; its collector consequently goes negative and places a corresponding bias on the base of transistor 29, which cuts off and removes the muting of the signal. If, during operation, the charge on capacitor 12 becomes sufficient to bias transistor 13 and the conductive capacitor 16 is discharged; transistor 23 then becomes non-conductive and transistor 29 is biased conductive to mute the amplifier. By rendering muting dependent upon both the current in and voltage across the load, the arrangement takes into account a reactive load. The charging resistor 22 for capacitor 16 is returned to a potentiometer comprising thermistor 20 and resistor 21 connected across voltageregulating diodes 17, 18 which are in series across the supply. Consequently a surge voltage on the supply line will bias transistor 23 non- conductive, whereby transistor 29 becomes conductive and mutes the amplifier. Thermistor 20 is placed in close proximity to the output transistors of the amplifier, so that excessive temperature causes its resistance to be reduced, again biasing transistor 23 non-conductive whereby transistor 29 becomes conductive and mutes. The Specification also describes the application of the invention to an arrangement in which there is a number of amplifying channels, incorrect operation of any one muting all (Fig. 7, not shown).

Title: Improvements relating to the control of pneumatic feed motors in metal spraying tools
IPC: B05B7/18
Filed: 1955-10-26
Abstract: 816,371. Spraying metal. STANTON, W. E., and COPAS Ltd., V. J. Oct. 26, 1956 [Oct. 26, 1955], No. 30567/55. Class 69 (3). In a metal spraying tool of the type in which a wire is fed by a feeding device driven by a pneumatically-operated motor to the sprayproducing point, the flow of air to the motor is controlled by a main valve which itself is controlled by a pilot valve, the latter being operated by actuating means responsive to the speed of operation of the feeding device, whereby the flow of air to the motor is reduced or increased as the speed of operation varies above or below a predetermined value. In the Figure, a turbine rotor 11 with blades 13 is keyed to a shaft 10 and housed in a chamber of the tool casing. Compressed air is supplied to the tool at 24 and passes through a duct 23 and past a flexible diaphragm 20 in a main valve chamber 21, and through ducts 25, 26 and 19 to drive the turbine. The turbine speed is controlled by varying the position of the diaphragm relative to the outlet of the duct 23, and this is effected by a pilot valve 32 which, depending upon the position of its head 33 relative to its seat 31, controls the flow of pressure air to the opposite side of the diaphragm via a duct 39, chamber 30 and duct 37. A lever 45 pivoted at 48 moves the pilot valve stem axially to open that valve when the turbine speed reaches a predetermined value, and for that purpose diametrically opposed bob-weights 40 are carried on cranked spring metal arms 41 attached to the hub of the turbine rotor. When the predetermined speed is reached the bobweights push a disc 42 axially along the rotor shaft against. a spring 44, and the forked upper end of the lever 45 is moved by the disc and the opposite end of the lever opens the pilot valve, causing the diaphragm to move towards the outlet of the air supply duct 23. The lever is pivoted on a stem 47 which may be axially adjusted by turning a knob 51 to control the gap between the upper end of the lever and the disc and hence the speed at which the pilot valve is opened.

Title: Improvements in or relating to a device for extracting bakery products from open top baking containers
IPC: A21B3/18
Filed: 1948-12-01
Abstract: 657,576. Conveyers. STEVENS, A. H. (Purity Bakeries Service Corporation). Dec. 1, 1948, No. 31131. [Class 78 (i)] [Also in Group VI] Baked bread is extracted from its open-tod tins 14 by automatically inverting and dropping each group of tins on knock-out bars 44 to discharge the bread. The full tins (secured together in groups) from the baking oven conveyer 21 are conveyed up by conveyer 24, Fig. 3, and guides 39 to an intermittentlyrotated drum 41 over which they slide to strike first against one of the impact members 43 on the drum to loosen the loaves. Further rotation of the drum 41 partially inverts the tins so that they fall against the spaced knockout bars 44 and each loaf falls out and strikes against an inverting bar 55 so that it falls in upright position on curved shoot 49 delivering it to a conveyer 51 (or 28, Fig. 1) which may lead it to a cooler 29 and then to a slicer and wrapper 31. The tins strike against curved deflector or knock-out bars 44 (which engage only the spacers 16 between the group of tins 14), down which they slide to a conveyer 53 from which they may pass to a cooler 35, Fig. 1, and then to a tin greaser 27. The drum 41 is stopped when one of the cam pins 72 thereon opens the switch 65. The conveyer 23 is normally stationary until it receives bread tins from the oven 22 which strike a board 58 to close switches 57, thereby completing a circuit through 102, switch 65 (later opened by cams 60 on the conveyer-belt 23), relay coil 101, wire 107, switches 57, wires 109 and 103, so energizing the conveyer motor 50 and closing contacts 108. Thereupon 107 is connected to 103 and held closed until cam 60 (on the conveyer-belt 23) trips switch 65, thus breaking the circuit to relay 101 to stop the conveyer. Conveyer 23 moves faster than the oven conveyer 21 but the succeeding conveyer 24 is still faster so that a predetermined minimum spacing of the tins is obtained.
Patent GB-412958-A (GB)
Title: Carburettors for internal combustion engines
IPC: F02M19/00
Filed: 1932-11-05
Abstract: 412,958. Spray carburetters. CARTER CARBURETOR CORPORATION, 2838, North Spring Avenue, St. Louis, Missouri, U.S.A. Nov. 5, 1932, No. 31301. Convention date, Nov. 7, 1931. Addition to 412,957. [Class 7 (iii).] The parent Specification relates to a carburetter having an air inlet valve which is opened by a suction or pressure operated mechanism as the engine warms up, to an extent determined by a thermally-responsive device. According to the invention, the valve is formed of two parts, one of which is connected to the suction or pressure operated means and is prevented from opening during cranking of the engine, whilst the other part is permitted to open to a limited extent during cranking and to open fully under the action of suction when the engine is running under its own power. In the down-draught carburetter shown, the air-inlet valve 43, Fig. 10, comprises a part 45 fixed to its shaft, and a hinged portion 47 which may be opened by suction against the action of a spring 48. When the valve is closed, a latch 49 carried by the part 45 contacts with a shoulder 50 in the air inlet, and positions a finger 49a in the path of a lug 51 carried by the part 47, to limit its opening movement during cranking. As the valve 43 opens, the latch 49 reaches a position in which the finger 49<a> does not interfere with the lug 51, and then the part 47 can be fully opened by suction. As soon as the engine commences to run under its own power, the lubricating-oil pump supplies oil past a spring-pressed check valve 71, Fig. 6, into a cylinder 64 to raise a piston 75, which, through a rod 80 and a cam-plate 61, Fig. 2, gradually opens the air-inlet valve to an extent determined by a heat-responsive device 52, which actuates a cam shaft 57 having cam surfaces 58, 59 which, by engagement with stops 62, 63 on the cam-plate 61, limit the movement of the valve. As the engine warms up, the heat-responsive device 52 raises the cam shaft 57 to allow the piston 75 to open the valve fully. When the engine is stopped, the check valve 71 allows the oil to flow out of the cylinder 64, and a spring 76 forces the piston 75 downwardly until the stop 62 contacts with the cam surface 58, partly closing the valve 43. As the engine cools, the heat-responsive device draws the cam surface 58 downwards to permit the valve 43 to close fully. Liquid fuel is supplied to the float chamber by a pump, and passes through a metering orifice, controlled by a needle valve operated by the throttle valve 24, to a common passage from which fuel is discharged at idling through a passage 40 to a nozzle 41 at the edge of the throttle valve, and, during normal running, through a nozzle 42 in the smallest of a series of Venturi passages 35. A pump operated by the throttle supplies additional fuel during acceleration through a separate nozzle.
