Title: Welding studs to surfaces
IPC: B23K9/20
Filed: 1966-07-29
Abstract: 1,138,894. Welding by pressure. FORD MOTOR CO. Ltd. 29 July, 1966 [20 Aug., 1965], No. 34079/66. Heading B3R. In welding a metal stud to a metal sheet contaminated with contaminants that tend to hinder welding, the stud and sheet are contacted, a potential difference is applied between the stud and sheet, the stud is removed from the sheet to generate a pilot arc, the contaminants are displaced by the energy released by the pilot arc from the sheet near the stud, a working arc is superimposed on the pilot arc to melt a part of the sheet and the stud is pushed against the sheet. The stud may be of austenitic stainless steel to be secured to an automobile body and the contaminant may be water, oil, grease, grime or the zinc of a galvanized coating which is vaporized by the pilot arc. The pilot arc is preferably supplied from a separate source of power, e.g. a rectified A.C. main voltage of a constant 157 volts and provides a power of 110,000 watts per square inch of stud area and an energy release of 5000 joules per square inch of stud. The working arc is provided by a capacitor.

Title: Multiple hoist apparatus
Inventor: SCHAPER DONALD WILLIAM
IPC: B66C13/00
Filed: 1960-10-06
Abstract: 905,565. Pulley hoists. MORGAN ENGINEERING CO. Oct. 6,1960, No. 34327/60. Class 78 (5). A hoist with variable mechanical advantage ratio includes a cable 12 reeved over an upper pulley block 22, a primary lower pulley block 26, at least one secondary lower pulley block 23, and locking means 19, 25 for releasably securing the pulley block 23 to the pulley block 21, yieldable stop means 36, 36a being provided for limiting upward movement of the pulley block 23 until overcome by force exerted upon it by the pulley block 26. Thus two different mechanical advantage ratios are obtainable according, respectively, as to whether the pulley block 23 is locked to, or released from, the pulley block 21. As shown, the cable 12 is in two sections, each of which is wound on a winding drum 11 and passes via a sheave on the pulley block 26 to sheaves on the pulley blocks 21 and 23 and finally to an anchorage 13 on a cross-bar 15 pivotally mounted at 16. The upper surface of the pulley block 26 is adapted to engage a corresponding lower surface of the pulley block 23 and is retained in this position as shown in Figs. 2 and 4 by means of arms 31, 31. The latter are pivotally mounted on the pulley block 23 and are apertured to engage lugs 34, 34, on the pulley block 26. Each arm 31 has a cam surface (Fig. 5, not shown) adapted to engage a leaf-spring 33 so that it is spring-loaded into both the retaining position shown in Fig. 4 and a retracted position (Fig. 3). The upper pulley block 23 has apertured lugs 25b which, when the hoist is sufficiently raised are adapted to be aligned with plungers 19 slidable in a block 18 rigid with the frame which carries the mounting of the winding drum 11. The plungers 19 are spring-pressed into an extended position and have cam-shaped ends so that they automatically engage with the holes in the lugs 25b when the pulley block 23 is raised to its limit of upper travel. In operation, when it is desired to immobilize the pulley block 23 and so work at a lower mechanical advantage and higher hoisting speed with the pulley block 26 only in operation, the arms 31, 31 are manually disengaged from the lugs 34, 34. The hoist is raised under noload conditions until the upper surface of the pulley block 26 engages stop-members 36, 36a. The latter are loaded by springs 38, 38a, which act through the stop-members 36, 36a, to hold the pulley block 26 while the pulley block 23 is further raised until the holes in the lugs 25b engage with the plungers 19. The hoist may then be lowered and the pulley block 26 alone will be in operation. The stop-member 36 also functions as a safety device to operate a switch 46 and stop the drive to the winding drum 11 when the load reaches its extreme limit of height. The springs 38 may be replaced by counterweights. The plungers 19 may be solenoid controlled.

Convention date, Dec. 23, 1931. [Class 38 (ii).] A polyphase inverter employing grid-controlled discharge devices comprises a self-excited single phase inverter and additional single phase inverters deriving their grid excitation from a phase shifting bridge circuit energized from the grid system of the self-excited inverter. In the three-phase arrangement shown, three single phase parallel type inverters are associated with the transformer T, and the lower one is rendered self-exciting by a system of condensers 11, 13 and a resistance 12 associated with the grids. Operation of the two upper inverters at appropriate phase displacement is effected by grid-potentials derived from two phase shifting circuits comprising respectively resistance 17 and capacity 18, and resistance 19 and inductance 20 in association with a winding 15 energized either directly or through transformer connections 14 from the winding 12. The frequency of the system may be varied by adjustment of the resistance 12, resistances 17, 19 being made adjustable also in order that correct phase relations between the several inverters may be maintained when frequency is varied.

Title: Improvements in electron discharge apparatus
IPC: H01J1/14
Filed: 1921-12-23
Abstract: 195,440. General Electric Co., Ltd., and Gossling, B. S. Dec. 23, 1921. Vacuum tubes. - In a device in which an electron discharge is obtained, independently of the presence of traces of gas, by means of a sufficiently steep potential gradient at the surface of the cathode, one or more cathodes are made of or coated with highly electropositive substances. Such a cathode may be produced by coating an anode of relatively electronegative material, for instance, nickel, with a salt of an electropositive metal, and passing a discharge between the anode and cathode in an exhausted container. The electropositive metal thereby liberated at the salt-vacuum surface can be released by evaporation, for instance, by means of a highvoltage discharge, the metal being deposited on the cathode. If a relatively volatile metal such as sodium is used, a rise in temperature of the cathode should be avoided. Thorium may 'be used as the electropositive substance. Specifications 155,554, 178,300, and 178,301 are referred to.
