Patent GB-968520-A (GB)
Title: Process for the extrusion of pre-sintered blanks or billets
IPC: B21C29/00
Filed: 1962-04-13
Abstract: 968,520. Extruding; working at specified temperatures. E. DURRWACHTER, and E. BOSCH. April 13, 1962 [May 15, 1961], No. 14306/62. Headings B3P and B3V. In the hot extrusion of pre-sintered blanks 4, the blank is surrounded during heating and extrusion by a protective coating 5 to exclude oxygen. The blank may be a combination of sintered tungsten-copper, silver-molybdenum, silver-nickel or silver-graphite; the extruded product is preferably used in the manufacture of electric contacts. Coating 5 may be a layer of brass foil for extrusion temperatures up to 800 ‹ C., a layer of copper foil for extrusion temperatures between 800-1000‹ C. and a layer of iron foil for temperatures above 1000‹ C. The press ram 2 has a concave head 3 of smaller diameter than the blank whereby after extrusion, Fig. 5 (not shown), substantially the whole of the coating remains in the discard; a small portion of coating in front of the extruded product may be removed by wire brushing. A shielding gas for the extruded product is admitted at 12 into a bush 11 and a cooling water spray 13 is provided. In another embodiment, Fig. 2 (not shown), the layer of foil is in two parts and after heating the covered blank in a furnace, the lower part is detached before introducing the blank into the billet container. This prevents any part of the coating being present at the front of the extruded product. Alternatively the coating may be of graphite and/or magnesium or aluminium oxide, possibly with an addition of titanium oxide, which oxides may be mixed with water-glass into a paste and baked on to the blank. A combination of a non-metallic coating and a foil wrapping may be used.

Patent GB-1006636-A (GB)
Title: A photoelectrically controlled flame or tool cutter
IPC: B23K7/00
Filed: 1963-04-11
Abstract: 1,006,636. Photo-electric line followers. STEWART-WARNER CORPORATION. April 11, 1963 [April 12,1962], No. 14607/63. Heading G1A. A flame or tool cutter is controlled by a line follower comprising means forming an image of the line to be followed on a photosensitive device and a member providing lateral displacement of the image to allow for kerf width. The member surrounds a support rigid with the photosensitive device and defines two non-concentric circular cylindrical surfaces in contact with one of which is a feeler mounted on the support. The screwing head includes a lamp housing 74 having six cavities 90 containing lamps 80 which illuminate the line to be followed (Fig. 1 not shown) through tapped holes 92. An image of the illuminated line is produced by a lens 67 secured in the top 68 of a cylindrical cup 64 which has the housing 74 removably fixed to it by a thumb screw 76. The top 68 of the cup 64 has slots 65, 66 through which screws 70. 71 pass to threadedly engage a flange 58 on the main support member 50 of the screwing head so that the cup 64 may have its vertical axis adjusted with respect to the axis 36 of the member 50 without relative rotational movement. This lateral adjustment is effected by means of an outer cylindrical member 96 having an inner cylindrical eccentric cam 104 which acts on a cam follower 98 secured to the flange 58 of the support member 50, the cam follower 98 and cam 104 being urged into engagement by a spring 110 acting on the shaft of the screw 71 and the cam surface. Thus rotation of the member 96 causes the cup 64 and the housing 74 to move laterally with respect to the axis 36 by virtue of the eccentricity of the cam 104, the outside vertical surface of the member being graduated to indicate the precise lateral position. In a further embodiment (Fig. 5 not shown) the lens 67 is fixed in the support member 50 and adjustment of the member 96 rotates a glass block structed in the central area of the housing 74, to provide displacement of the image of the line. Specification 995,421 is referred to.

Abstract: 646,547. Radio receiving circuits. STANDARD TELEPHONES & CABLES, Ltd. June 4, 1948, No. 15148. Convention date, June 5, 1947. [Class 40 (v)] Muting is derived from an off-tune discriminator circuit. In a frequency-modulation receiver, Fig. 2, the discriminator 3 is set to one side of the true signal frequency so as to produce a positive D.C. potential when the receiver is in tune. This is used to unblock a lowfrequency amplifier 7, being applied to the grid in opposition to a cathode bias which otherwise biasses the valve to cut-off. The grid may be shunted by a biassed rectifier 10 which in conjunction with series resistance 11 prevents the applied positive potential becoming excessive. The anode circuit of the valve may include a relay, Fig. 3 (not shown), utilized to close a signalling circuit when the receiver is in tune. To prevent closure of the circuit by an unwanted signal close to that desired, an auxiliary valve 18, Fig. 4, may be provided, having in its anode circuit a further relay, the contacts of the two relays being in series. The discriminator 3 is modified to supply to the grid of the valve 18 a D.C. potential equal and opposite to that supplied to the valve 7, so that for signals other than the one desired the anode current of one or other of the valves is insufficient to operate the corresponding relay. In another embodiment, Fig. 5 (not shown), the valves are utilized as a push-pull L.F. amplifier ; they may alternatively be used solely for operating relays, Fig. 7 (not shown), which have additional contacts arranged in series in the anode circuit of a separate L.F. amplifier. The arrangement may also be applied to an amplitude-modulation receiver, Fig. 6 (not shown), by providing a separate discriminator circuit in parallel with the detector.
