Title: Improvements in or relating to arc welding apparatus
IPC: B23K9/10
Filed: 1959-08-12
Abstract: 883,223. Supply systems for welding arcs. WESTINGHOUSE ELECTRIC CORPORATION Aug. 12, 1959 [Aug. 20, 1958], No. 27543/59. Classes 38 (2) and 38 (4). In a welding system as disclosed in Specification 718,871 wherein a transformer T having a main secondary winding TR supplying an arc welding circuit SL1, SL2 through rectifiers 56a-56f and variable reactors TV1-TV3 and an additional secondary winding also connected to the welding circuit through further rectifiers, the additional winding CAD is coupled to one of the reactor windings so that an increase in the main welding current due to a short circuit induces a higher voltage in the additional winding to burn out the short circuit. The winding CAD is held externally to the other windings by means of a clip 11 so that it may be easily replaced, and the 3-phase arrangement of the earlier Specification is replaced by a singlephase circuit. A circuit breaker 15 and rheostat 13 control the additional current.

Title: Improvements relating to number dials for automatic and semiautomatic telephone systems and the like
IPC: H04M1/34
Filed: 1926-11-03
Abstract: 284,764. Siemens Bros. & Co., Ltd., and Garrod, E. R. Nov. 3, 1926. Addition to 178,936. Impulse transmitters for automatic exchange sytems. In an impulse transmitter of the finger-hold type in which a slipping cam masks the impulse wheel during a portion of the return movement of the dial, the engagement of the cam with the wheel is effected by a spring- controlled device on one member engaging holes in the other member. A spring 2, Figs. 2 and 3, on the cam 10 is provided with a pip 3 passing through the spring to coact with a series of holes 5 in the wheel 9. Normally the projection 34 on the cam engages a stop 35. When the dial is turned the cam moves with the wheel until a finger 12 engages the stop 35, when the cam slips with respect to the wheel. If the dial is forced round too far the pip 3 is not in engagement with the required hole 5, but when the members return, a hump 8, normally carried past the impulse-spring operating member 21, is held thereby until the pip engages the next hole in the rotating wheel, thus preventing a false impulse. The wheel and cam continue to rotate together until the members 34, 35 contact, when the cam is stopped and impulsing begins. In a modification, the spring 2 forces a ball 7, Fig. 7, through an opening 4 in the cam to coact with counter-sunk holes 5 in the wheel. In this case, if the dial is forced round too far. the countersinking of the holes 5 is sufficient to hold up the cam until the ball engages the required hole.

Title: Improvements in delivery mechanism for use in printing machines
IPC: B65H33/10
Filed: 1937-10-11
Abstract: 489,821. Delivery apparatus for printing - machines. HOE & CO., Ltd., R. (Hoe & Co., Inc., R.) Oct. 11, 1937, No. 27579. [Class 100 (i)] Delivery apparatus for printing-machines comprises stop means causing the products to pass from a gripper-cylinder to a conveyer, the stop means and the gripper-opening devices at timed intervals being rendered operative at a different point to that at which they operate normally so as to displace a count product. As shown, the folded products of a newspaper press pass between guides 14 to a cylinder 11 the grippers 21 on which are normally actuated by a fixed cam 25 to release products carried thereby and drop them on to a moving conveyer 15, Stops 27 strip the products from the grippers 21. At intervals determined by a cam 49, auxiliary stops 51 are moved into the path of the products on the cylinder 11 in advance of the stops 27, and at the same time an auxiliary cam 36 is moved into operative position to open the gripper 21 approaching the stops 51 at a correspondingly earlier time, so that the product carried thereby drops on to the conveyer 15 in an advanced position relatively to the other products and separate them into counted batches. The stop 51 and cam 36 are carried by a lever 41 actuated by the cam 49. Where the conveyer 15 travels in the same direction as the delivery side of the cylinder 11, the count product is delivered later instead of earlier than the other products.

Abstract: 518,150. Dental equipment. SIEMENS-REINIGER-WERKE AKT.-GES. Sept. 22, 1938, 'No. 27667. Convention date, Jan. 28. [Class 81 (ii)] A container for dental instruments, from which the instruments together with their connecting cables, flexible tubings or the like are adapted to be pulled out in an approximately horizontal direction against the action of a spring or the like, has the cables a and beach anchored at its inner end in the container c and wound within the container over a pulley-like system of reels d, e, f and g, h, i respectively, which act in the manner of pulleytackles, the reels of each system being disposed in horizontal planes with their axes at right angles thereto and one reel . of each system, i.e., d and g being adapted to be horizontally displaced against a spring force, such as that from spring 2 transmitted by the flexible member 12 and lever y fulcrumed at x to enable the respective instrument to be pulled out of the container. The reels h, i may be displaced into a bulge k on the side of the case and on which may be mounted a heater m and control switch n. The reels d and g may travel on rails u, an adjustable spring stop s co-operating with a cam t to relieve the tension on the instrument cable after it has been withdrawn a pre-arranged amount. In order to keep the tension in the cable constant the flexible member 12 runs over a template z the radius of which is arranged in each position to compensate for the increase in force exerted by the spring, and variation in effective length of the lever y, and other less apparent variations due to friction and change in direction of forces upon movement of the reels. During the movement of the lever y a pin 18 may co-operate with a toggle 19 of a switch 3 thus switching on the current when an instrument is withdrawn and switching off on release. When not required for use the instrument is in the position p but on pressing the knob q a pin 5 depresses a spring pawl 6 allowing the extended spring r to bring the instrument to the position P.

Air jets from holes 25 in tubular members 22, 23 and 24 extending radially from a hollow shaft 15 impinge on to the underside of the sieve and prevent clogging. The shaft-and tubular members are rotated by a motor 26 and air is fed to the shaft and tubular members via a pipe 12, a sealed tube 11, and inlets 16, 17. Scraper arms 27 attached to the shaft prevent the build up of material on the walls. An air jet may be positioned. in the drum 10 to agitate the coarser particles and to carry back fine particles into the main stream.

Abstract: 811,285 Filling blasting cartridges. CANADIAN NDUSTRIES Ltd. Sept. 4, 1957 [Sept. 12, 1956], No. 27921/57. Class 9(1) A machine for filling gelatinous and powdered explosives into cartridge cases, which may be of paper, comprises a framework 1 on which is a plate 2 supporting a hopper 3 and an upper framework consisting of vertical columns 4 and a plate 5. A casing 6 supports the drive for paddles 7, which agitate the explosive, the drive being taken 'from a hydraulic motor (not shown). Part of the hopper base is provided with openings communicating with nozzles 9 and aligned with hollow cutters 10 carried by a plate mounted on a carrier 12, which can be reciprocated by means of a hydraulic cylinder 13. Tamping rods 14 extend from the pistons of cylinders 15 into the cutters. Cartridges 16 placed in a shuttle 17 are brought into the filling position below the nozzles 9 by raising a plate 18 by means of a cylinder 19. After the hopper has been filled with explosive the paddles 7 are set in motion to produce a uniform mass. A shuttle-load of empty cases is placed on the plate 18 and the filling cycle started by raising the plate until the nozzles enter the cases 16. The plate 18 by hydraulic means stops the paddles and actuates cylinder 13 to push the cutters into the explosive. At the end of the cutter stroke the rods 14 push the explosive from the cutters and compress it in the cases 16 until a valve reverses the stroke of the rods and cutters. The operation is repeated until the cases are filled, when the plate 18 is lowered and the shuttle removed. The height of the paddles 7 can be adjusted according to the depth of explosive in the hopper.
