Title: Improvements in welded tap or lead to a conducting foil and method of making the same
IPC: B23K9/00
Filed: 1959-05-13
Abstract: 874,406. Transformers. GENERAL ELECTRIC CO. May 13, 1959 [May 15, 1958], No. 16427/59. Class 38 (2). [Also in Groups XXII and XXXVI] An electrically conducting tap member is welded to the apex of a fold or pleat in the electrically conducting foil of a transformer winding. In making a transformer winding comprising aluminium foil wound on an insulating cylinder 10 in a plurality of separated groups 11 with paper insulation between the turns of the foil and with taps 15 on the winding, the cylinder 10 is mounted on a rotary mandrel 20, Fig. 2, adjacent a supply reel 21 of foil and a supply reel 25 of paper. The foil passes over a pair of fixed spaced members 31, 32 and below a pair of vertically movable clamp members 34, 35. When it is desired to secure a tap to the foil a member 50 extending between the members 31, 32 is raised as in Fig. 4 by operating a wheel 51 to deform the foil which is held in tension. A notched block 56, Fig. 5, is then manually or automatically pressed against or slid along the foil to shape the latter to a fold or pleat with the tension relaxed. The members 50, 56 are then withdrawn and the fold is pinched between a pair of tap leads 57, 58, Fig. 7, with the apex of the fold projecting above the leads. The clamp members 34, 35 are then lowered to contact the leads and an inert gas shielded non- consumable electrode welding torch 45 on a rack 46 (Fig. 2) is lowered and traversed across the foil to weld the foil to the leads. The clamps and electrodes are withdrawn and the foil wound on to the core. A single split tap lead may alternatively be employed.

Title: Improvements relating to alarm clocks
IPC: F23L1/00
Filed: 1935-06-06
Abstract: 457,979. Alarm clocks. JUNGHANS AKT.-GES., GEB., Schramberg, W³rtemberg, Germany. June 6, 1935, No. 16472. Convention date, Aug. 7, 1934. [Class 139] An alarm clock wherein a stopping lever 3 by entering a recess in a disc 2 connected to the alarm escape wheel 1 always stops the latter in the same position, is characterized by a cam 14, 15 which rotates more slowly than the wheel 1 and which cam, after a certain number of revolutions of the said wheel each controlling a signal of short duration, prevents the stopping lever 3 from again entering the said recess and from again stopping the alarm escape wheel 1, so that a signal of longer duration is given. The cam 2 rigid with the alarm escape wheel 1 coacts with the lug 4 of a lever 3 which is rigid with levers 7 and 8 and is turned clockwise about pivot 19 by spring 17. Lever 7 has a pin 20 coacting with a twelve-toothed ratchet 9 which is turned once an hour through its spring 12 connection with a wheel frictionally mounted on the minute spindle 10. Lever 8 coacts with a cam 14, 15 which is on the alarm spring shaft 13 and has a leaf-spring 16 covering the lower dwell 15 ; the shaft 13 rotates clockwise and drives the shaft of wheel 1 during the alarm. At the alarm release time, the hammer shaft 6 is freed by a settable face-cam in the known manner, but the top of lever 3 still locks an arm 5 rigid with shaft 6. Spring 17 and pin 20 hold ratchet 9 whilst shaft 10 continues to rotate, until spring 12 has been stressed sufficiently to overcome this hold. Wheel 9 then rotates suddenly one tooth, moving parts 7, 3, 8 to the left so that arm 5 and shaft 6 are released fully. The alarm sounds and parts 1, 2 rotate counterclockwise until, after one rotation of cam 2 (alarm duration of two seconds), lug 4 drops off the high part of cam 2 and lever 3 again locks the arm 5. During this time, the top of lever 8 is on the low dwell 15, the cam 14, 15 rotating clockwise. At the end of five minutes, the next tooth of wheel 9 again releases the parts to give a second short warning signal; lever 8 still being on dwell 15. After another five minutes and at the next, third tooth of wheel 9, however, lever 8 rises on to the high dwell 14 and since the end of lever 8 runs on part 14 and the outer surface of spring 16, it holds the lever 3 to the left, so that it can no longer relock the arm 5 and hammer spindle 6. The alarm then continues to ring until the alarm spring runs down or the alarm is stopped manually in known manner. During winding cam 14, 15 is rotated counterclockwise so that the end of arm 8 returns under spring 16.

Abstract: A cast iron, steel or light metal packing member for a piston (Group XXVI) is coated at the areas subjected to wear with a layer of either molybdenum or molybdenum alloy having such a high content of chemically-uncombined molybdenum as to obtain substantially the high wear characteristic of pure molybdenum. The layer may be applied, after treating the surface of the article by sand blasting, grinding or chemical etching, by thermal decomposition of volatile molybdenum compounds, e.g. molybdenum hexacarbonyl, sputtering, electrolytic decomposition or by flame spraying from two pistols directed at the same point on the base. The pressure gas used in the spraying process is preferably ammonia to reduce the oxide content of the applied layer, and the base may be heated prior to or during the process.
