Abstract: 408,241. Arc welding. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Chapman, V. J. ; 25, Lakewood Avenue, Schenectady, New York, U.S.A.) Sept. 30, 1932, No. 27219. Convention date, Oct. 1, 1931. [Class 39 (iii).] Arc-welding machines are adapted for use with stick electrodes 1 by providing the electrode holder 2 with an upwardly-extending rod 6 which is engaged by the feed rolls 10, 11 and which carries means, such as an arm 42, for operating a button 24, to stop the welding operation after a predetermined feed movement. In the form shown in Fig. 2, the holder is urged away from the work by cords 20 passing over a spring drum 19, and the regulated feed drive by the rolls 10, 11 as exerted against the action of this spring until the welding operation is interrupted by the stop button 24 which may be arranged as described in Specification 301,045, [Class 39 (iii)]. On operating a bell-crank lever 18, the roll 11 is released and the holder is retracted by the spring device 19, a spring 23 serving to cushion the return movement. Fig. 6 shows electrically-controlled means, including a limit-switch 45 operated by an arm 46 on the rod 6, for automatically effecting the release of the roll 11 from the rod 6 and the engagement therewith of a roll 56 to effect a reverse drive of the rod 6 through a motor 47. Similarly, the arm 46 by engaging a limit-switch 44 causes a reversal of movement at the upper limit of travel of the rod 6. The electrode is oscillated by lever mechanism 28, 25, 27, 29 operated by a variable throw crank 39 driven from a motor 31. Reference has been directed by the Comptroller to Specification 111,026, [Class 39 (iii)].

Filed: 1923-10-31
Abstract: 206,505. Landis & Gyr Akt.-Ges. Oct. 31, 1922, [Convention date]. Special quantities, registering.-An adjustable alarm acts in conjunction with a maximum demand indicator and comes into operation as soon as the consumption in a specified time interval exceeds a predetermined limit. Coupled with the recording tram of the meter is a spindle 3, to which is fixed a four-armed piece 8<1> carrying a pointer 9 which engages a lug 7 on a non-return hand 6. A cam 11 is fastened to the piece 8<1> by screws 10, adjustment being provided for by slots so that a mark 13 on the pointer 9 may be set adjacent to a selected point on a scale on the edge of the cam. The cam 11 has a portion of greater diameter than the remainder, so that when this portion engages a pin 15 on a bell-crank lever 14 a switch 19 in the circuit of an electric bell or other alarm is closed. In a modification the piece 8<1> is replaced by a disc with a series of holes into which fit a pin against which an arm is pressed by a torsion spring. This arm carries at its end a pin which operates the switch 19, further rotation of the pointer 9 causing tightening of the spring, so that the alarm circuit remains closed until the return of the pointer to a point below that at which the alarm is set to operate. The bell may be replaced by an optical alarm, and the alarm may be operated mechanically.

Abstract: 842,598. Valve amplifying and pulse shaping circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. Sept. 21, 1956 [Sept. 27, 1955], No. 27425/55. Class 40(6). A distributed amplifier is modified so as to constitute a pulse shaping circuit. In one embodiment, in which the input is applied to terminals A Fig. 1, of the grid delay line and the output obtained from terminals B of the anode delay line, the components of the lines are so chosen that one or more of the partial outputs obtained from each of the valves V1-3 reaches the output terminals with a time delay which differs from that sustained by the remainder. The relative amplitude of this partial output may be set by adjustment of the gain of the valve concerned, e.g. by variation of a cathode resistor R1. The partial output of different time-delay may also be reversed in phase, either (Fig. 2, not shown) by feeding the valve concerned from the opposite side of a balanced grid delay line, or (Fig. 3, not shown) by enterposing a phase - reversing transformer in the grid connections. Alternatively, (Fig. 4, not shown) an extra phase - reversing valve may be used, or (Fig. 5, not shown) the valve in question may be of the secondary-emission type and an in-phase output obtained from the secondary emission electrode. In a balanced distributed amplifier, comprising two chains of valves V1 &c., and V1<SP>1</SP> &c. respectively, Fig. 6, fed from grid lines L1 &c. and L1<SP>1</SP> &c. respectively, the anode connections of one pair, e.g. V2, V2<SP>1</SP> may be reversed. In a further embodiment (Fig. 7, not shown) the arrangement shown in Fig. 1 is modified by reversing the connections of the anodes of the valves V1, 2 to the interposed inductance L3. Specifications 460,562, and 517,516 are referred to.

In boring apparatus comprising a drill 10, a drill motor 8 adapted to follow the drill down the hole, and a flexible tube 3 supporting the drill and motor down the hole, a conveyer 1 between the hole and the tube winding drum 4 relieves the drum of load when the drill and motor are in the hole. At the start of drilling the hole (see Fig. 3) the tube from the drum passes over a guide 15 and is connected to drill pipe 9 fixed to the motor. As the drill sinks into the earth guides 20 are removed, and when the pipe is below the surface the guide 15 is lowered to the position shown in Fig. 1 and the conveyer is engaged with the tube. The guide 15 is pivoted at 17 and engages an instrument 19 giving an indication of the weight of the apparatus in the hole. The drill, motor and pipe combination is moved in the hole by the conveyer, the reel being rotated to feed tube to, or receive tube from, the conveyer. A mast 26 (Fig. 5) pivoted at 29 has a slidable support 25 adapted to engage the part 27 of a tube joint to obviate the joint passing through the conveyer and to facilitate the changing of drums.

Abstract: 306,113. Schneider et Cie. Feb. 17, 1928, [Convention ,date]. Ordnance breech mechanism. - The breech is opened automatically during the run out of the gun by means of a lever C, Fig. 1, which is keyed at c to the breech-block B and during the run out abuts by means of a pin c' at its end on a bearing surface at the end of a channel-shaped arm E alongside the breech, as shown in the dotted positions I, II, III. The cartridge. is ejected during the latter part of the opening movement of the breech-block B and lever C, and before the completion of the run out. A spring J is simultaneously compressed by a plunger I connected by a link C<2> to a pivot c<2> on the lever C. After this operation, the pin c' of the lever C runs on the upper flange e<1> along the top of the arm E until the run out is completed. To close the breech, a handle K<3> is temporarily operated, and this by means of a finger K denects. the arm E about a vertical pivot E', whereby the flange e<1> releases the pin c' and the spring J returns, the lever C and the breechblock B to the closed position shown in the figure. During recoil, the pin c<1> rides against the web e of the arm E between the top and bottom flanges e<1>, e<2>. This web is obliquely disposed relatively to the axis of the gun, and the pin c<1> is spring mounted on the lever C and yields during the recoil until it snaps over the end of the arm E. This arm is normally urged outwards against a fixed stop by a spring buffer, which is compressed when the arm E is deflected inwards by means of the finger K and handle K<3>. The pivot E<1> of the arm E is carried by a plunger F cushioned by a spring F<1> which takes up the shock of the finger c<1> on the end of the arm E when the breech is opened during the run out of the gun.

An aircraft propulsion unit is rotatably carried at the wing tip of a vertical take-off aircraft and comprises a fan mounted in a duct 12 which carries a movable annular extension 13. The extension 13, which has a sharp leading edge 26, lies adjacent the duct 12 in high speed forward flight as shown in Fig. 2 and when the engine is rotated vertically rams 32 are operated to move the extension forwardly.
