Title: Improvements in or relating to electric arc welding
IPC: B23K9/14
Filed: 1941-08-22
Abstract: 550,727. Uniting by fusion. MARTIN, H., and MUREX WELDING PROCESSES, Ltd. Aug. 22, 1941, No. 10720. [Class 83 (iv)] In automatic arc welding with a standard length electrode 1 provided with a flux coating arranged when the arc is burning to project beyond the core and engage the work to serve as a spacer for the core, the electrode is carried in a holder or trolley 3 capable of travelling by gravity down an inclined runway 4, the electrode being arranged at a steeper inclination than the runway so that the movement under gravity simultaneously maintains the arc by pressing the tip of the electrode into contact with the work and causes the top to travel along the seam. The electrode is carried in a swivelling clamp 2 angularly adjustable in the trolley and the runway is hinged at 5 to a base 6 and clamped at its slotted end by a pin 7 to the slotted end of a hinged support 10 so that the angle of inclination of the runway can be varied. The lower end of the electrode is positioned by two guides 13 extending from the runway to the support. The electrode is sufficiently rigid to act as a support for the trolley during operation. The arc continues until the electrode is used up or until the trolley engages an adjustable stop 16. The trolley when out of use is held up by a hook 14. When fillet welding lap or T-joints the runway lies in a plane inclined at 45 degrees to the vertical plane containing the length to be welded, the base 6 of the runway coinciding as in the previous case with the position at which the weld terminates. The electrode is inclined to the vertical as well as to the horizontal. When welding long seams a number of similar units of the form previously described may be erected side by side over the length of the weld and may be operated simultaneously or one may be operated while the next is being installed in position. The current may be supplied at a high voltage such as 100 volts at current density of 20,000- 30,000 amps per sq. in. of core so that the molten core of the electrode is expelled violently from the tip to leave a cup acting as an insulating spacer.

Title: Improvements in electro-magnetically operated switches
IPC: H01H50/22
Filed: 1944-06-06
Abstract: 580,150. Electromagnetic switches; controlling motors. ELECTRICAL APPARATUS CO., Ltd., WALTON, J. R., and BARBOUR, R. H. June 6, 1944, No. 10847. Classes 38 (iii) and 38 (v)] An electromagnetic switch, particularly adapted to act as a star delta starter for an electric motor, has a member 24 biassed towards a neutral position, actuated upwards from this position to establish a circuit connection when an electromagnet 10 is energized, and adapted to return past its neutral position when the electromagnet 10 is de-energized. so that on the next energization of the magnet, the member 24 is moved downwards to establish a different circuit connection. The magnet 10 attracts an armature 11 which actuates a bell crank lever 14 the arm 20 of which carries a wedge 21 adapted to engage either below or above a wedge 23 on the member 24 which is pivoted on links 27, 30 and centralized by a spring 32. A bar 40 also moves up and down with the member 24 and carries cams which engage rollers on the ends of spring-biassed contact members. In the application to a star delta starter, Fig. 1, depression of a start button X completes the circuit to the magnet 10 which thereupon moves the members 24, 40 upwards so that contacts P, Q, R connect the supply L@, L2, L, to the ends A<2>, B<2>, C<2> of the three motor windings while contacts N, O connect the other ends of the motor windings producing the star arrangement. A contact M also completes a maintaining circuit and a control J completes a circuit through a secondary winding E and a thermal relay F. After a time interval the latter operates moving an arm G into engagement with a contact 3 breaking the maintaining circuit so that the magnet 10 is de-energized. The members 24, 40 move downwards past the neutral position and a cam H, closes at H a circuit re-energizing the magnet 10 but as the wedge 23 is now in its dotted position, Fig. 5 the member 24 is now moved downwards still further and completes at PQRSTU the delta connection for the motor. A maintaining circuit is also established through K. To return to the "off" position a delayed action stop switch such as described in Specification 577,372 is actuated. If it is desired to switch the motor in star only, as when inching, an "inching" switch may be used which interrupts the circuits through M E and F and so prevents the automatic change over from star to delta.
