Title: Method and apparatus for automatically regulating the welding current in arc welding
IPC: B23K9/095
Filed: 1962-04-18
Abstract: 942,635. Welding by fusion. HACKETHALDRAHT-UND KABEL-WERKE A.G. April 18, 1962 [April 18, 1961 (2)], No. 15149/62. Heading B3R. [Also in Division H2] Arc welding apparatus used in the manufacture of metallic sheathing for electric cables wherein a metallic strip is shaped into a tube and the seam continuously welded comprises a generator A the output of which is linearly dependent upon the speed of the seam being welded relative to the welding electrode, the output of the armature G of the generator A being used to bias an inductor I in the supply to the welding electrode so that the welding current is linearly proportional to the speed of the seam. Closure of a mains switch St starts the mechanism for moving the tube which mechanism drives the generator A and after a delay sufficient to the tube moving mechanism to reach the minimum working speed a timing relay Z 1  closes a switch S to supply the welding electrode over a transformer T, the inductor I and a rectifier R. Energization of the field of the generator A is effected by the transformer T over a rectifier R 1  and a potential divider comprising resistors 1, 2, 5 the resistor 5 being adjustable to allow the minimum setting of the welding current consistent with the minimum speed of the tube. A resistor 3 is provided in the biasing circuit of the inductor I to allow for the type of material being welded. A second timing relay Z 2  is provided whereby a resistor 4 in the field energization circuit is short circuited after the current surge incident upon the start of welding has passed. In a second embodiment the relay Z 2  is controlled by means of a photo-cell which is responsive to the arc. The rectifier R is omitted in an A.C. arc system.

Title: Improvements in or relating to the production of sintered uranium dioxide
Inventor: RUSSELL LEWIS ERIC
IPC: G21C3/62
Filed: 1960-04-29
Abstract: A sintered body of high density containing uranium dioxide ore as mixture thereof with, preferably 10-30% plutonium dioxide, for use as a fuel element in a fast neutron reactor, is obtained by heating a compressed body of uranium dioxide, or mixture thereof with plutonium dioxide, to at least 1300 DEG C. in an atmosphere consisting of carbon dioxide, or a mixture thereof with carbon monoxide.  If CO2 alone is used the maximum sintering temperature is 1550 DEG C.  The CO/CO2 volumetric ratio may range from 1:100 to 100:1.  The preferred range for a 10% PuO2, 90% UO2 being 1:100 to 1:10 and for a 30% PuO2 70% UO2 from 1:20 to 1:1, during sintering at 1400 DEG -1600 DEG C. A sintered body having a metal / oxygen atomic ratio 1,98 to 2.02:1 is produced by cooling in a reducing atmosphere, preferably a CO/CO2 atmosphere of volumetric composition range 1:10 to 100:1 although hydrogen or hydrogen containing water vapour may be used.  The density of the sintered product, depends upon sintering time and attains a maximum value and diminishes thereafter.  Optimum times, determined by experiment, are between 3-6 hours.  Thus in Example 1 a mixture of 10% plutonium dioxide 90% uranium dioxide were ball milled and polybutyl methacrylate in toluene were added as a binder.  After drying the granules were double pressed into pellets, which were heated at 400 DEG C. then to 1500 DEG C. in a CO2 atmosphere, and maintained at 1500 DEG C. for 4 hours.  The resulting pellets had a theoretical density of 96% and had an oxygen/metal ratio of 2,14/1. Other examples refer to the use of CO/CO2 mixtures during sintering and H2 or H2 and water vapour during cooling.  Specification 881,883 is referred to.

Abstract: 484,947. Sewing. SCHEIBEL, K., and WURKER, C. June 7, 1937, No. 15782. [Class 112] In producing blind-stitch seams, the advance and return movements of the looper are effected in the same path, which crosses the needle path at an acute angle. The curved needle 12 is carried on the arm 8 rocking with the shaft 10 which is rocked bv the rod 1. The work is bent by passing over the bender 14 and is held by a presser foot 15. The work is fed over the bender by a feed wheel 16. The needle-rocking lever 4 has an arm 18 with a cam slot 19 engaged by a pin 20 on the lever 21 carrying a shaft 22. The shaft 22 has a projection 26 carrying the looper 27. When oscillated by the arm 4, slot 19 and pin 20, the looper 27 is resiliently pressed against a cam track 29 to give it its proper motion to ensure seizing the needle loop. In the form shown in Figs. 5 and 6, the oscillatory movement is produced by shaft 34 and the link mechanism 35, 36, 37. The work bender 41 is carried by a lever 42 which is reversible to suit thick or thin work. To reverse it, the lever 42 is pushed sidewise by the knee lever 60 to disengage shoulders. The bender can then be turned through 180 by hand. The bender is adjustable in height for varying thickness of work or for depth of penetration of the needle by an eccentric 56 operating on the short arm 421 of the arm 42.
