Filed: 1934-03-01
Abstract: 434,430. Tie-on labels. POLLAK, J. E., 20, Holborn, London-(Brehmer.Geb.; Plagwitz, Leipsic, Germany) March 1, 1934, No. 6612. [Class 73] A machine for attaching the strings to tie on labels comprises means for feeding a length of string from a supply, passing a length in loop form through the label, and drawing the ends through the loop by means of a catcher having one or both jaws movable, the jaws being initially closed to pass through the loop, then opened to embrace the ends, and closed again before withdrawing the catcher through the loop. Figs. 1 and 3 show the machine in elevation and plan. The string is drawn from a supply reel B by a gripper 34 mounted on an oscillating arm 28 and furnished with a spring-returned jaw 35 operated by end stops 37, 38. The string passes through a spring-controlled guide 21<a>, Fig. 20, and the required length is cut off by a pair of shears actuated by stud and slot mechanism from an arm 26 operated bv a cam 29 oscillating with the arm 28. The jaws 34, 35 push the guide to the left to seize the end of the string at the beginning of the stroke of the arm 28. The string is supported by pairs of pivoted jaws 86, and a vertically reciprocating hook 40 carries a loop downwards through the label, placed against stops on the table 17. The projecting loop is moved from the hook 40, and into position for co-operation with the catcher, by means of a member 51 mounted to slide on the underside of the table and operated by a stud 48 on the arm 28 engaging a cam slot 49<b> on a slide supporting the member. A similarly operated member forms an obstruction over which the loop is folded. The catcher comprises a pair of curved, pivoted arms 65, 66, Fig. 15, mounted on a rocking shaft 60 and provided with mating gaps through which the ends of the string can slip freely. The arms are opened to embrace the string, after they have passed through the loop, by a rocking member engaging a stop 69.

Title: Power supply and method for metal surfacing
IPC: B23K9/10
Filed: 1967-02-13
Abstract: 1,117,853. Supply systems for metal surfacing. GLENN PACIFIC. 13 Feb., 1967 [2 June, 1966], No. 6676/67. Heading H2H. [Also in Division B3] A power supply system for surfacing base metal 33 by traversing the metal with a consumable electrode 29 and creating an intermittent arc between the electrode and metal, comprises a step-down transformer rectifier arrangement 1, 7, a capacitor 13 whose value exceeds 80,000 microfarads and an adjustable inductor 25 having a range of zero to five millihenries. It is stated that such selection of capacity and inductance, particularly the former, provides precise control of depth of penetration, contour and arc starting, the system being primarily applicable to large diameter electrodes, e.g. up to a quarter of an inch, while also enabling arc starting on smaller diameter electrodes to be achieved with no " blasting." In operation the electrode 29 is driven at constant speed to effect a cycle of momentary short circuit, arcing, " pinching off " of the electrode and finally open circuit, the capacitor 13 respectively charging and discharging during the open and short circuit conditions and its large value (80,000 to 700,000 microfarads) enabling the frequency of discharge to be independent of the value of the supply voltage. The adjusted value of the inductor 25 determines the value of the discharge current and its lag angle and duration. In a modification of the circuit of Fig. 1 to provide a greater range of control, an adjustable reactor is connected between each transformer secondary winding 3 and its input to the recti- 'fier 7, Fig. 2 (not shown), or an adjustable inductor is connected between an output terminal of the rectifier 7 and the capacitor 13, Fig. 3 (not shown). The circuits described may be used for arc welding.

Abstract: 776,311. Rectifying. SIEMENS-SCHUCK. ERTWERKE AKT.-GES. March 7, 1955 [March 5, 1954], No. 6704/55. Class 38 (2). [Also in Group XXXVII] Dry metal rectifiers are arranged in groups connected in series and/or parallel, some being switched in or out as the current and/or voltage conditions change, so that maximum working efficiency is maintained. D.C. lines 3, 4 are supplied from three-phase A.C. lines R, S, T through transformer 1 and dry metal rectifiers arranged in groups 2a, 2b, 2c ... 2m connected in series. To vary the output voltage, taps on the primary windings 1a of transformer 1 are altered by a regulating switch 5 which also operates a switch 121 to connect more or fewer of contacts 122 to bus-bar 120. Corresponding coils C of electromagnetic switches such as 14, 15, 16 are then energized or de-energized to open or close the switches and thus connect in circuit or short-circuit some of the groups of rectifiers 2a-2n as necessary to have the least number of groups in series which will withstand the reverse voltage. The control may be automatic. In a modification groups of rectifiers connected in parallel in each phase may be connected into or out of circuit automatically in dependence on the load current, Fig. 2 (not shown). The numbers of series and parallel groups may be varied together to correspond with joint voltage and current regulation. The armature circuit of a number of D.C. motors, e.g. 30, supplied from A.C. source 51 through rectifiers 35, may be controlled by controller 50. The latter affects further controllers 45 which vary the voltage ratio of the supply transformers 40 and the number of rectifiers connected in series. Fine speed regulation, by regulators 74 in the field windings is effected by controller 67. Voltage regulation may be by chokes whose values are varied by a D.C. current which may be used to control the number of rectifiers in circuit. Selenium, germanium and silicon rectifiers are specifically mentioned. Where the apparatus is operated by remote control, indicators signalling the need for rectifiers or their connection in the circuit may be provided.
