Abstract: 548,969. Automatic control systems for welding electrodes. KITTEL, F. W. B. (Linde Air Products Co.). March 29, 1941, No. 4271. [Class 38 (iv)]  Arcs.-To prevent the sticking of the electrode to the work in fusible electrode welding, with or without a flux, the maximum rate at which the electrode can be fed is limited. The voltage between electrode 1 and work 6 is applied through a transformer 10, rectifier 11 and adjustable potentiometer 12 (with or without a filter circuit), in series with an opposed adjustable D.C. voltage from a potentiometer 13, to the grid of an electron or gas filled valve 20 in the armature circuit of a D.C. motor 21 feeding the electrode. Owing to a glow discharge tube 30 connected across the potentiometer 12 through a resistance 31 in the grid circuit the voltage of the grid and the motor speed are limited. Due to the characteristic of the tube the limited feeding rate during starting is nevertheless greater than the maximum during normal working.

Title: Improvements in coin-freed mechanism
IPC: G07F5/04
Filed: 1942-04-14
Abstract: 556,021. Coin-freed apparatus. HARPER, P. S., and HARPER AUTOMATIC MACHINE MANUFACTURING CO., Ltd. April 14, 1942, No. 4900. [Class 27] Relates to coin-freed apparatus of the kind described in Specification 541,223, in which a coin or coins is or are temporarily retained in edgewise relation in a stacking shoot 9 and supported by the appropriate one of a number of interceptor elements 1 - - 4 adapted to extend into the shoot at a level corresponding to the number of points to be intercepted thereby, the next coin C<SP>1</SP>, after the stacking shoot is full, being directed by the uppermost stacked coin into a branch shoot 11 down which it falls to operate the coin mechanism (not shown), this coin C<SP>1</SP> acting on means such as a tail 10 of an interceptor element to release all the coins in the stacking shoot. According to the present invention the interceptor elements are controlled by a selector, such as a handle or knob 21, connected to each interceptor element through a bar 13, 14, 15 or 16 adapted to turn the element about its pivot 5. In the construction shown each element 1 - - 4 normally lies with its head projecting into the shoot 9 and can rock to an extent determined by a pin 6 working in a slot 7. The selector knob 21 rotates a boss having radial arms 20 each adapted to engage a lug 19 on one of the vertically-sliding bars 13 - - 16. Each bar has three lugs 23 adapted to engage three of the pins 6 on the four elements 1 - - 4, so that when the knob 20 is turned to any desired position one of the bars is raised by its lug 19 and its three lugs 23 work three of the interceptors so that their heads 8 are clear of the shoot 9 but the fourth interceptor is left blocking the shoot. Thus, in the position shown the bar 16 has been raised and interceptors 1, 2, have been withdrawn so that the first coin inserted comes to rest on interceptor 4, four coins are needed to fill the shoot 9 and a fifth coin to free the apparatus and release the stacked four coins. In other positions of the knob 20, one or other of the interceptors 1, 2 and 3 is left projecting into the shoot 9. If the apparatus is to be operated by one coin the entrance to the shoot 9 is blocked by a ball 24 when a sliding bar 26 having a lug 27 is raised by the knob 20. This ball is normally free to be pushed aside by a coin, but when the bar 27 is raised a lug 25 thereon locks the ball in the entrance of the shoot 9, so that a single coin is diverted to the shoot 11 and frees the apparatus. In a modification the interceptors 1 - - 4 are so supported that normally they do not project into the shoot 9, and when a selector bar is operated it acts on the corresponding interceptor and causes it to project into the shoot.
