Title: Improvements in and relating to electric resistance welding machines
IPC: B23K11/31
Filed: 1949-08-31
Abstract: 678,010. Welding by pressure. EISENBURGER, K. Aug. 31, 1949 [Sept. 2, 1948], No. 22627/49. Class 83 (iv). [Also in Group XXXV] In an electric resistance welding machine for spot or seam welding, wherein the casing of a supply transformer forms an essential portion of the secondary of the said transformer, the electrodes 3, Fig. 2, are connected with the periphery surface of the transformer casing 1 by non-articulated holders, at least one of which comprises a resilient part, both electrode holders being otherwise rigid. The electrode holder 5 shown is carried by an arm 7 fixed to a resilient plate 9, which forms either a partition or the end wall of the casing 2. The other electrode holder 4 is fixed directly to the end of the casing 2, and the electrodes 3 are moved into engagement with the work by a hydraulic or pneumatic piston 11 against the action of a spring 10. The piston 11 is controlled by the handle 12 constructed as a rotary valve and coupled with a switch so that the electrodes are energized only after they have reached their operating positions. Alternatively the arm 7 is resilient and the plate 9 rigid or both are resilient. In the construction shown in Fig. 4, the electrode holder 5 is carried by a spring bar 26 subjected to torsional stresses tending to press the holder 5 towards the holder 4, and the electrodes are moved apart by the piston 11. The operating pressure of the electrodes may be regulated by an additional spring 10 adjustable by a handle 14 and nut 27. In a further construction the electrodes are separated by applying pressure to the resilient plate mounting the arm 7, by means of an expansible capsule. Fig. 7 shows a roller seam-welding machine in which a rotable electrode shaft 45 is mounted in a tubular boss 46 in a resilient wall 9 of the transformer casing 2, and is rotated by bevel wheels 49 through a continuously adjustable gear in a box 50. The shaft 45 may be provided with an axial passage for cooling water and carries a roller electrode 48 below which is disposed a roller electrode 52 carried by a freely rotatable shaft 51, mounted in a bracket 53. The electrode pressure is adjustable by rotating a spindle 55 having a threaded end engaging an internally threaded arm depending from a boss 54 on the arm 45. Stops 57, 58 on the spindle abut against plates 59, 60 confining a spring 63 the compression of which provides the electrode pressure. The electrodes are moved apart by means of a pedal 64 and linkage 65, 66.

Title: Improvements in or relating to cathode structures for electron discharge devices
Inventor: MURPHY ARTHUR YOAKLEY
IPC: H01J1/20
Filed: 1953-08-19
Abstract: 773,580. Thermionic cathode constructions. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 3, 1954 [Aug. 19, 1953], No. 22817/53. Class 39(1). An indirectly heated cathode structure comprises an insulating disc having an aperture, a cathode comprising a tubular body closed at one end and containing a heater wherein the edges of the open end of the cathode body are seated on the insulating member around the aperture, the heater extending through the aperture in the insulating member into the cathode body so that the end of the heater remote from the tubular cathode body is closely surrounded by the insulating wall of the aperture. In one form, Fig. 3, an insulator 1 of moulded and fired ceramic is provided on one or both sides with circular ridges 3 which prevent metal deposition occurring in operation from forming a continuous path from the centre to the edges, is countersunk at 4 and thickened at 5 and has a central aperture from which three longitudinal slots extend radially. The cathode 7 is closed at one end by an integral portion thereof or by a separate cap and has three strip legs 8,120 degrees apart which in assembly are passed through the slots and their ends bent over. A connecting tape 9 welded to the end of one of legs 8 is threaded through a hole 10 in the insulator. The heater 11 of " molytungsten " wire coated with insulation is thus enclosed partly by the cathode tube 7 and partly by insulator 1; it may contact insulator 1 but not legs 8. In an alternative construction holes can be drilled in the insulator around the central aperture and the cathode legs passed through them, the ends of the legs being bent away from the axis of the central aperture. The invention can be applied to cathode ray tubes, especially for television purposes, klystrons and travelling- wave tubes. The heater may be multiply folded instead of helical.

Patent GB-498336-A (GB)
Title: Improvements in compositions for treating and preserving wood
IPC: B27K3/44
Filed: 1937-08-23
Abstract: A wood-preserving or coating composition comprises a solution of coal tar in a petroleum oil fraction having an aniline point below 50 DEG F., preferably below 20 DEG  F., and even as low as -80 DEG  F. Such oil fractions boiling below 400-450 DEG  F., are suitable for making coating compositions, while fractions boiling below 400 DEG  F. and having a flash point above 150 DEG  F., preferably above 200 DEG  F., are more suitable for making wood preservative compositions. Suitable fractions may be obtained by subjecting petroleum oils, especially California and asphalt base crudes, to distillation, extraction, cracking or hydroforming.  In the example a kerosene distillate fraction of a naphthenic crude is extracted with liquid sulphur dioxide and heated to remove the more volatile components. The residue (60 per cent) is subjected to destructive hydrogenation at a temperature of 930-1050 DEG  F., and a pressure of 3000 pounds per square inch in the presence of catalysts containing oxides or sulphides of the metals of Group VI.  The hydroformed product is distilled and the fraction boiling above 410 DEG  F. and having an aniline point of -70 DEG  F. is mixed with a tar consisting of the non-aqueous distillate obtained by carbonizing bituminous coal.
