Title: Improvements in the methods of manufacture of electrical resistors
IPC: H01B1/24
Filed: 1950-03-21
Abstract: 667,720. Resistance coatings and deposits. WELWYN ELECTRICAL LABORATORIES, Ltd. March 21, 1950, No. 6985/50. Class 37. Carbon is deposited on insulating bodies, such as ceramic or vitreous material in the form of rods, tubes, or plaques, by the decomposition of hydrocarbon gas at high temperature, the bodies being placed in a gas-tight container which is heated in a furnace to and maintained at the required temperature until the decomposition has proceeded to the required stage, and the container being then separated from the furnace so that it may be rapidly cooled. As shown in.Fig. 1, a furnace consists of a frame 1 in which is mounted a refractory tube 2 on which the winding 3 is placed. The furnace rests on a frame 4. The ends of the refractory tube 2 are open to the atmosphere and adjacent to the ends are two supports 5 mounted on brackets 6. The supports 5 may be in the form of a semi-circular cradle or may comprise an arrangement of rollers. In the refractory tube 2 is placed a furnace cylinder 7 made from high temperature alloy, closed at one end. 8 and provided with a flange 9 at the other end. A plate 10 is bolted to the flange 9 with the interposition of a gasket. Attached to the plate 10 is a handle 12 for inserting or withdrawing the cylinder 7 from the furnace and which can serve as a means of entry to the cylinder for entry of inert gas or vapour, withdrawal of products of reaction, or for producing a vacuum. The ends of the cylinder may be water-cooled. Alternatively the cylinder 7 may be fixed and the furnace mounted on a trolley so that.it can be wheeled away from the furnace tube. The cylinder 7 is withdrawn from the furnace at a temperature greater than 200‹ C. A gas furnace may alternatively be used.

Toy flying-machines; Land-wheels and skids.- In toy aeroplanes provided with a landing- carriage, the carriage is constructed so that it may be collapsed against the frame or fuselage to facilitate packing. Fig. 1 shows a toy aeroplane provided with skids f, f<1> carrying wheels g, g<1>, in which the skids are connected to the main frame member a by parallel triangular frames h, i, j and l, m, o pivoted at k, n respectively to the member a, so that by moving the frames about these pivots, the carriage can be folded against the member a. The carriage is held in the extended position by a triangular member p, p<1> hinged to the axle h and provided at the top with a fastening q detachably engaging a. member r on the frame a. When the carriage is folded, the fastening q may engage a second member farther along the frame a. In a modification, the base oof the triangular frame l, m, o may be omitted, a cross-member being provided higher up between the members l, m. Where there is only one skid, the parallel frames are of rectangular or loop form.

Title: Programme control unit with index register
IPC: G06F9/32
Filed: 1959-02-27
Abstract: 872,750. Digital electrical calculating-apparatus. STANDARD TELEPHONES & CABLES Ltd. Feb. 27, 1959 [March 4, 1958], No. 6996/59. Class 106 (1). An index register has an additional line in which the instruction address is stored, a return loop being provided between said additional line and an address-calculator unit, whereby at each programme step the instruction address can be modified and stored in said additional line. An instruction word comprises seven positions, two for the operational characteristic, one for the index and four for the operand address The word is fed in series mode to the control unit over lead P. Initially control counter HSZ is in position t1 to cause line selector ZW to select the additional line I10 of the index register M which is of the ferrite core type. When HSZ is stepped by a clock pulse to t2 the instruction address stored in I10 is transferred to address register AR. While HSZ steps through positions t3-t6 the information in AR passes round the loop comprising lead r, gate T9 and address-calculator unit ARW, one being added at time t3 by means of gates T6, T8 whereby the new instruction address is stored in AR. If the associated computing apparatus is free an " x " signal is returned to enable HSZ to advance to position t7, whereupon gate T14 passes the instruction address over leads v to the associated computing apparatus. In positions t9, t10 the new instruction address is returned to line I10 of index register M. The operational characteristic is fed to the operational register OR with HSZ in positions t11, t12, while in t13 the index entered on lead P sets line selector ZW. With HSZ in position t14 matrix control device MS transfers the index value in the selected line to address register AR, this index value being restored at t15. With HSZ in positions t15-t18 the operand address entered on lead P is added at ARW to the index value and the sum stored in AR. At t19 the operational and address registers OR, AR are connected to the associated computing apparatus which returns a clearing signal y whereupon the cycle can begin again in respect of the next programme step.

Title: Improvements in or relating to processes and apparatus for the production of toric surfaces
IPC: B29D11/02
Filed: 1962-02-22
Abstract: 963,407. Grinding; turning; machine-tool details. LENTILLES OPHTHALMIQUES RATIONELLES S.A. Feb. 22, 1962 [March 22, 1961], No. 7009/62. Headings B3B, B3D and B3T. A process for the production of a toric surface on a body of resilient material, such as in the production of a contact lens, comprises forming a surface of revolution on the body, compressing the body between two opposed forces acting at right angles to the axis of revolution of the surface, machining the surface so deformed in such a manner that it again becomes a surface of revolution, and finally releasing the compressive forces. The lens 40 may be of the form shown in Fig. 1 in which the surface of revolution is a spheroidal cap and deformation is effected by compression along a base circle diameter. The flanged base 39 of the lens is gripped by the upstanding portions 29 of four L-shaped jaws 27 which are slidably mounted in bores in a holding element 20 and urged inwardly against the action of outwardly-acting springs 31 by the rotation of the element 20 in a surrounding housing 1 having an oval bore 6, Fig. 2, constituted by two circular arcs of radius R with centres O displaced a distance d as shown. Depressions 28 in the base of the element 20 enable it to be rotated to position the jaws so as to provide the desired degree of deformation of the lens. When suitably deformed, the lens is turned or ground, and polished. In the modification shown in Figs. 4 and 5, the lens 60 is mounted in the lower end of a bore 57 in a vertically-movable support plate 55 and compression of the lens is effected by causing a slide 67 to urge the lens against an oppositelydisposed straight edge 64 on the support; the slide 67 is operated from a screw 57 whose tapered face 74 contacts a peg 68 on the slide. Upon suitable deformation of the lens the support 55 is lowered so as to bring the lens into contact with melted wax in a cup 53, and the subsequent machining operation is carried out when the wax has hardened.

Abstract: 487,082. Supplying current to moving and rotating conductors. FORGROVE MACHINERY CO., Ltd., and GROVER, F. March 11, 1937, No. 7164. [Class 38 (i)] [Also in Group XVII] The rotary gripper jaws of a twist wrapping machine are electrically heated by elements 2 connected by insulated flexible leads 4 to carbon brushes 5, the other terminal 3 being earthed. Each brush 5 slides in a recess 6 in the tail of its associated jaw, and is urged by a spring 7 into contact with a slip ring 8 mounted in an insulating block 9. The slip ring is curved to a radius struck from the pivot 12 of the jaw so as to accommodate itself to the opening and closing of the jaws, which is effected by a rack rod 13.
