Abstract: 1478260 Butt welding control systems V A SIDYAKIN A N SABANTSEV E M LAPIN and E A MACHNEV 23 July 1975 30714/75 Heading H2H [Also in Division B3] In a butt welding process (see Division B3), a glow discharge is initiated between two workpieces 5, 6 by an auxiliary transformer 71 around the entire butt ends of the workpieces. After a predetermined interval a programming unit 78 energizes contactor 83 so closing contacts 84- 86 to actuate a pulse former 70 resulting in an increase in the current intensity of the glow discharge so changing the discharge into an auxiliary arc. The voltage across the workpieces 5, 6 is therefore brought down to be less than the open-circuit voltage of a welding transformer 57 so allowing an electronic switch 64 to operate. During alternating voltage half waves across the welding transformer 57, immediately after the auxiliary arc has been struck, control pulses from the pulse former 70 are applied to fire back-to-back thyristors 68, 69 to bring the welding transformer 57 into operation with a sharp increase in arc current. At the end of each half-wave of the welding voltage, the switch 64 disconnects the welding transformer 57 from the workpieces and the voltage is applied from the auxiliary transformer.

Abstract: 1405629 Drives for endless conveyers C U PEDDINGHAUS 6 July 1972 [12 July 1971 (2)] 31594/72 Heading B8A [Also in Division G3] A conveyer device for conveying bars longitudinally to a machine which processes the bars comprises a conveyer having a drive means which can be switched off after predetermined lengths of bars have been advanced to the processing machine, the bar-length being preselected whilst the previous bar is being processed. As shown, bar length selector switches A, B, C are interconnected by lines 40-42 to a stepcounting mechanism 43 operated by a coil 44. The coil 44 is energized by the actuation of a switch 46 by trip cams 45 spaced along the conveyer, or, by R.C. timing circuits, not shown. The mechanism 43 actuates a relay 47, 48 to switch off the conveyer drive (not shown) when a predetermined bar length has been conveyed. The selector switches are associated with stores 32-37 of a programme storing circuit. Each store has a self-hold relay 53. Each store is connected to a contact of a step switching mechanism 49 actuated by a switch 55 associated with a cutter of a processing machine, not shown, and actuated after an operation has finished by a trip cam 56. Alternatively, the mechanism 49 can be stepped by manual switches 61, 62. The conveying operation is carried out by the mechanism 49 switching in steps from conveying one bar section to conveying the next bar section in accordance with the next higher store. After a sequence programme has finished the mechanism 49 returns to its starting position. In Figs. 4-6 (not shown), the conveyers are of the endless type and have bar-pushers (69, 105).

Abstract: 195,686. Commercial Aeroplane Wing Syndicate, Ltd., and Booth, H. Nov. 29, 1921. Floats for aerial machines.-The skins of hulls, floats &c. of aircraft are formed of a single series of strips of wood sufficiently narrow to be bent edgewise as well as facewise to enable curved frames to be curved without tapering the strips in width. The width of the strips is also not great compared with their thickness. The edges may be plain or tongued and grooved as shown in Fig. 4. To give increased stiffness to any desired part, strips of various thicknesses, as shown in Fig. 4, or strips of varying thickness from end to end may be employed, or strips of both forms may be used. To enable reliable joints to be made between strips having plain edges, or to enable tongues of substantial size to be used, the strips may be rrade thicker than otherwise required and recessed or grooved on their undersides as shown in Fig. 3 to reduce their weight.
