Title: Improvements in arc welding apparatus
IPC: B23K9/10
Filed: 1937-06-17
Abstract: 493,225. Automatic control systems. JONES, L., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 17, 1937, No. 16912. [Class 38 (iv)] Arcs.-A method of welding seam joints by an atomic hydrogen process consists in moving the electrodes along the seam at a constant distance therefrom, controlling the distance apart of the electrodes so as to maintain the arc voltage substantially constant until the electrodes reach a point approaching the end of their travel and then moving the electrodes relatively near together to reduce the heating sufficiently along the part of the seam which is welded last to prevent molten metal running back along the seam. A motor controlling the distance apart of the electrodes is energized to move the electrodes together or apart according to whether the arc voltage is too high or too low, a coil VRC connected across the arc operating a three position armature to energize one of two contactor coils each corresponding to one direction of rotation of the motor, the third position of the armature permitting de-energization of the motor. The switch S in series with the coil VRC is closed only when the arc is burning. A resistance CR in series with the coil VRC is short-circuited manually or automatically by a switch T as the electrodes reach the point at which heating is to be reduced with the consequence that the motor is energized to move the electrodes nearer together by a predetermined amount. According to the Provisional Specification, the contactor coil which when energized causes the motor to move the electrodes together, is provided with an additional energizing circuit incorporating a normal open switch and when the point at which heating is to be reduced is reached, the normally opened switch is closed and a switch in series with the other contactor coil is opened. The contactor control means may be dispensed with.

These passages extend inwardly from holes in a baffle or sealing ring E, and the chambers G have bottoms H which prevent the heavy liquid from reaching the central part of the bowl. The upper ends of the chambers G may be open for the discharge of liquid, or discharge holes may be provided in the side walls of the chambers. The lighter liquid is discharged through a regulating screw J in a recess K in one of the chambers G. The inner side of the recess may be bounded by a wall L or the side walls may be continued to meet the wall of the distributor A. The screw J may be placed above or below the discharge point of the heavy liquid. In the modification shown in Fig. 5, the passages F are made as channels in a solid plate E. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the modification shown in Figs. 6, 7 (Cancelled) in which separate channels G are provided in the neck of the hood B to receive the heavy liquid from the tubes F. Small drain channels S are arranged between the channels G and open into outlet holes T situated in the same plane as the regulating screw J. In the event of the lighter liquid leaking between the part H and the wall of the distributor A, it is discharged through the channels S. For the purpose of reducing weight, recesses are arranged between the channels G. This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for the automatic forming of a shaped loop of wire from wire stock
Inventor: HOLROYD ERIC
IPC: B29D30/48
Filed: 1951-07-20
Abstract: 720,368. Angular bending. DUNLOP RUBBER CO., Ltd. July 11, 1952 [July 20, 1951], No. 17221/51. Class 83 (4). In apparatus for the production of shaped loops of wire for cycle tyre beads an intermittently rotated former carries clamping and shearing means operated during a dwell between rotations. The former comprises a back plate 26 with pivoted sectors 28, 29 linked to a radially adjusted sector 27. The former is mounted on a shaft 39 rotated with harmonic motion by a slider crank mechanism, Fig. 4 (not shown). The former is held stationary between rotations by a spring-urged locking pin. A cam 37 operating the clamp 35 and a plural cam 38 operating the shearing mechanism 36 are mounted on a shaft 39. The cam 38 lifts a rod 74 to raise a pivoted blade 71 co-operating with a block 70 in position to shear the wire and lifts a shear operating rod 75. An edge cam 68 operates the rod 75 to effect shearing. The cam 38 also raises a rod 79 after shearing to lift a gripper 72 vertically and to swing it clear of the wire to allow the forward loop to be removed. A push-rod 82 is then operated by cam 37 to project a bolt under the loose end of the wire to position it under the clamp. In order to compensate for slight shortening of the wire after shearing the free end of the wire is deflected over a projection 34 on the back plate 26 by displacement of a guide 25 with spring jaws. The free end of the wire is fed through guide 25 and is clamped by the clamp 35. The former is then rotated and a loop is formed. At the dwell period cam 38 lifts and swings the blade 71 to effect shear and clamp 35 is released by push-rod 79. The loop is removed and bolt 83 through cam 37 positions the stock for clamping. Specifications 720,367, 720,369 and 720,370 are referred to.

Title: Improvements in and relating to gramophones with automatic record disc changing means
IPC: G11B17/16
Filed: 1948-06-29
Abstract: 651,919. Automatic gramophones. KLING- LER, M. June 29, 1948, No. 17419. [Class 40 (ii)] In an automatic gramophone, in which records are supported on a centre shaft and released one by one on to the turntable, the records are supported on the holding lug 33 of a latch member 31 pivoted at a point 32 and having a locking lug 34 which, during a recordreleasing operation, is outwardly displaced by an upward movement of a rod 27, so that the records 4<SP>1</SP> are displaced sideways and rest on the lower edge of a recess 36 in the shaft 31 while the lowermost record falls to the turntable 13. In order that the undersides of the records may be played, the centre shaft is made to revolve in opposite direction to the turntable by means of a thrust bearing in which a thrustplate 7 rigid with the centre shaft effects a reverse drive of the turntable supporting sleeve 12 by means of balls located by a fixed cage 9. The pick-up movements are controlled by means of a cam-wheel 16 which performs a halfrevolution during each automatic cycle. During one half-revolution the arm 20 rotates counterclockwise from the position shown in Fig. 1, and moves the arm 23 on a shaft 24 clockwise so that the arm 26 lifts the recordreleasing rod 27. During the second halfrevolution of the cam-wheel 16 the shaft 24 is not rotated and a record is not released. A contact disc 46, Fig. 7 (not shown), is provided which is manually set according to the number of records in the stack, and is moved one step by the pin 21 on the arm 20 each time the arm 20 completes a revolution, so that the motor circuit is broken at the completion of the final automatic cycle.

Abstract: 649,302. Ships' tanks. WARREN PETROLEUM CORPORATION. June 30, 1948, No. 17669. [Class 113 (ii)] [Also in Group XXIX] A cargo unit for transporting liquids in ships comprises a group of tanks having a deck hole coverplate rigidly securing the tanks in assembled relation, equalizer pipes to connect the lower ends of the tanks and equalizer pipes to connect the upper ends of the tanks, each equalizer pipe having a coupling so that any tank may be disconnected from adjacent tanks or the tanks inserted and removed as a unit. A number of tanks 8, having welded flanges 13 by which they are connected to a deck hole cover-plate 10, rest on a series of longitudinal and transverse webs 5, 6 attached to an inner bottom 4 of a ship. The complete group passes through a hole in the deck 9 and the deck hole cover-plate is secured to the deck at 11 in a water-tight manner. Thus, if the connection at 11 is broken, the whole group may be isolated. The upper and lower ends of the tanks communicate by means of equalizers 15, 17 which have couplings 16 and 18 respectively so that any tank may be disconnected from its neighbours for removal, and a single eduction line 19 for the unit is fitted. Relief valves 20 may be fitted to one or more tanks and a valved back pressure inlet connection 23 may be fitted to one tank only.
