Title: Apparatus and method for butt welding
Inventor: NOMURA HIROKAZU
IPC: B23K9/025
Filed: 1970-03-19
Abstract: 1,260,644. Welding by fusion. NIPPON KOKAN K.K. 19 March, 1970, No. 13441/70. Heading B3B. In butt-welding together a row of plates A, the opposite end edges of one plate are simultaneously welded by a pair of devices 17, 18 to the adjoining edges of a pair of plates between which said one plate is located. The plates of the row are first tack-welded together at a preparatory station before being taken along a conveyer line to a station, including the devices 17, 18. The pair of welding devices 17, 18 are supported by a saddle-shaped carriage 9 which is movable, in the direction of the weld seams, along a transverse beam 4 of a travelling gantry. The latter is moved along rails 8, parallel to the plate row, by an electric motor 6 drivably connected to rail-engaging wheels 5a, and is locked in position by rail-clamping units 36. The motor 6 drive may be two-speed to provide for fast approximate and slow precise gantry positioning. The carriage 9 is moved along the beam 4 by a drive mechanism 10 acting through pinions and beam-mounted racks 12. The welding devices 17, 18 are hingemounted, at 19, on carriers 14, 15 which, to adjust the distance between said devices and thereby accommodate different seam pitches, are mounted on adjusting screws 13 driven by a motor 16 through reduction gearing. The devices 17, 18 each carry, successively in the direction of welding, a sensing roller 22, a flux-spraying opening 23, first, second and third electrodes 24-26, and a flux-retrieval opening 27. The electrodes are positioned at the seams by servomotors 20. The sensing roller 22 engages a weld-preparation V-groove and signals groove variations to an electrical control circuit which, in turn, through adjustment servomotors 37v, 37h, corrects vertical and horizontal electrode alignment. Flux retrieved at 27 is returned to a separating, treatment and supply tank 28 for re-issue at 23. Filler wire 21 from reels 29 is fed to the welding zones by feed mechanisms 30. Welding cables 35 are carried by trolleys 34 movable along gantry rails 33. An operator stand 31 is provided. On seam completion, the electrodes and sensing rollers are lifted, and the carriage is returned.

Title: Improvements in grid-biassing arrangements for grid-controlled valves
IPC: H03K4/12
Filed: 1940-08-27
Abstract: 542,092. Valve circuits. GENERAL ELECTRIC CO, Ltd., and MIDGLEY, D. Aug. 27, 1940, No. 13510. [Class 40 (v)] In valve circuits of the condenser-relaxation type or of other types in which the mean anode current is variable or adjustable in operation, the grid bias is maintained constant by inserting a gas-filled tube in the cathode lead. In the time-base circuit shown, a condenser 5 is charged through a variable resistance 6 and discharged through a triode valve 1, usually gasfilled. The tube 8 is connected in parallel with the cathode resistance 10 and its anode is connected to HT+ through a resistance 7. The grid 3 of the valve 1 is connected to a tapping on the resistance 10. The arrangement gives a constant voltage between the cathode 2 and HT-, and therefore a constant bias on the grid 3, despite variations in the mean anode current which occur when the frequency is changed by varying the resistance 6. Specifications 424,429 and 539,603 are referred to.

Title: Improvements relating to regulating systems operating by pressure responsive means
Filed: 1941-10-23
Abstract: 596,968. Automatic control systems for aircraft. SPERRY GYROSCOPE Co., Inc. Oct. 23, 1941, No. 13656. Convention date, Sept. 28, 1940. [Class 38 (iv)] Speed: fluid pressure.-In order to maintain constant the air-speed of an aircraft any type of servomotor controlling the air-speed or adjusting the engine throttle is controlled by a movable member responsive to the difference between an air pressure variable with the air-speed of the craft and an air-pressure dynamically generated from the surrounding air and independently maintained. This latter pressure may be adjustable to enable the airspeed maintained to be varied. The arrangement is stated to be unaffected by altitude and temperature changes. A Pitot tube P is connected through a restricted conduit 4 with one end of a bellows chamber 1 and an air pump 5 electrically driven at constant, but adjustable speed, is similarly connected by a conduit 4<1> to the other end of the bellows chamber. A common dividing wall 2 carries a contact 10 co-operating with fixed contacts 11, 11<1> so that movement due to unbalance between the pressures in the chamber will energize selectively magnets 12, 13 to actuate a pawl 17 to adjust the throttle control 20 in a direction to cause a change in engine speed, tending to maintain a balance. At the same time a magnet 9 is energized to open a valve 7 in the wall 2 to equalize the pressure difference and restore the wall to its initial position, whereby adjustments of speed are effected in steps. In a modification a self-loading reversible electric motor adjusting the throttle is directly controlled by the contacts 11, 11<1>. These contacts may be carried by a manually-adjustable member to provide another means of determining the air speed maintained. Specification 596,969 is referred to. According to the Specification as open to inspection under Sect. 91, the invention is stated also to be applicable to the control of the climbing or diving angle of the craft. This subject-matter does not appear in the Specification as accepted.

[Also in Group XIX] In an arrangement for counting pulses arising randomly from a plurality of sources, a temporary store in the form of a multicathode tube is provided for each source. The stores are scanned sequentially, stored pulses being read out to a common total counter. As described, there is provided for each pulse  source a ten-cathode tube 11, the guide electrodes 13, 14 of which are continuously pulsed  by 50 c.p.s. alternating current. Cathodes 1 and 6 are connected to positive potential on a line 19 to arrest the stepping of the discharge and are also connected to the anode of a trigger tube 22, cathodes 2 and 7 are connected to an output line 18, cathodes 3, 5, 8 and 10 are earthed and cathodes 4 and 9 are connected to the anode of a trigger tube 26 and also to the positive bias 19. The trigger electrode of the tube 26 is connected to one of the sources of pulses to be counted and the trigger electrode of the tube 22 is connected to a commutator switch 27 to which are also connected other circuits similar to that described for the other pulse sources. The output leads 18 for the various storage tubes 11 are connected over diodes 30 to a common total counter 35. Switches 31, 32 may be opened to cause the discharge initially to pass to cathode 3 or 8. Assuming the discharge to pass to the cathode 3, the next input pulse neutralizes the bias on cathode 4, allowing the discharge to pass to the cathode 5. When next the switch 27 causes the trigger 22 to fire, the bias on cathode 6 is neutralized, allowing the discharge to pass to cathode 8, an output pulse being produced by the cathode 7. The commutator switch 27 may comprise a multielectrode discharge counting tube. Reference has been directed by the Comptroller to Specification 822,331.
