Filed: 1965-09-15
Abstract: 1,109,582. Bundling chain link fencing. BARNARDS Ltd. 30 June, 1966 [15 Sept., 1965], No. 39452/65. Heading B8C. Chain link fencing is telescoped longitudinally and wound into roll form, Figs. 5, 6 (not shown), by feeding it on to a travelling support arranged to wind it and moving at a speed slower than that of the feed. As shown, a roll 16 of the fencing is fed via a drive roller 8 to a slack upper run 2 of an endless canvas conveyer belt 1 driven by a roller 4. A speed-reducing drive 15 causes the peripheral speed of roller 4 to be less than that of roller 8. The fencing is thus telescoped and wound on to a roll 180. A number of parallel conveyer belts 1 may be provided to accommodate fencing of greater width or several pieces of fencing, Fig. 1 (not shown). Idler rollers 12, 10 may have adjustable collars 14, 11 respectively to restrain various widths of fencing laterally. The roll 180 may be completed by stretching the last layer to its normal length and tying it with wire to form an external " skin." It may then be removed by means of a hoist 19. As illustrated in Fig. 7 (not shown), the finished roll may be expelled by taking up the slack in conveyer 1 by means of a movable roller, thus causing the run between rollers 3, 4 to straighten out.

Title: Multiple pulse generator
IPC: G11C11/56
Filed: 1971-08-31
Abstract: 1369902 Magnetic storage devices; non contact making switches J R WIEGAND and M VELINSKY 31 Aug 1971 40516/71 Headings H3B and H3X A multiple pulse generating device comprises a bundle of magnetic wires held together by a dielectric to form a cylindrical body. Each wire is of a generally uniform composition and is treated by heating and work hardening so that its core portions are of lower coercivity and retentivity than its outer, shell portions. The wires may have helical easy axes of magnetization. Normally the magnetization of the core is in the opposite direction along the wire to that of the shell, and forms a flux path for the shell. When an external field is applied along the wire, either by a coil or permanent magnet, and the field is increased, the magnetization of the core is suddenly aligned with the external field as the influence of the shell is overcome. This sudden change of magnetization, which occurs by passage of a domain wall along the core, will induce a sharp pulse in an adjacent output coil. Figure 1 shows an external field coil 22 and an output coil 24 wound on a bundle 17. The output from the coil 24 is shown against the applied field in Figure 5, each step representing one of the wire cores being aligned with the applied field. The device may be used in a magnetic memory of high signal to noise ratio. In Figure 2 a permanent magnet is held adjacent a bundle of the wires by a flexible material 30, so that when the magnet is moved by pressing button 38 multiple pulses are obtained from the coil 24. Several such push-button devices may be connected to the same output winding. By changing the cores for ones with a different number of wires a different number of output pulses are obtained.  Manufacture:-The wires are prepared from an Fe-Ni alloy, and the preferred wire is 48% Fe-52% Ni having 10,000 grains/mm<SP>2</SP>, and a diameter of 0À012 inches. The wire may be drawn from a rod of 1-1¢ inches diameter through successive dies at some 75 feet/minute, each die giving a 20% reduction in area. This drawing is done at a temperature which produces the desired grain size, and is followed by room temperature work hardening, e.g. a 2¢% strain. A helical easy axis may be obtained by twisting the wire while it is tension. The resulting wire is cut into lengths and potted.

Title: Improvements in and relating to logical devices
IPC: H03K19/09
Filed: 1959-12-01
Abstract: 900,425. Transistor logical circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 1, 1959 [Dec. 1, 1958], No. 40805/59. Class 40 (6). A circuit unit for performing logic operations comprises two transistors each having a plurality of input connections to its base and its collector electrode connected to a common output circuit for the two transistors. Fig. 5 shows a circuit in which an AND operation performed by each transistor is followed by an OR operation in its common collector circuit; in this circuit earth potential represents unity and positive input potential and negative output potential represent zero. In Fig. 7, transistor 110 conducts, causing the output to represent unity if either of inputs A, B is binary zero; similarly a binary one output is obtained if either of inputs C, D is binary zero. A binary zero output is then obtained only if all the inputs are binary one. In Fig. 9, transistor 136 functions as an AND gate while transistor 138 gives zero output only when both input signals are unity, the common collector load 140 serving as an OR gate following the two transistors. Fig. 11 shows a two-stage circuit in which one input to the circuit of Fig. 5 is provided by a similar circuit in which, however, the conductivity types of the transistor and the polarities of the supplies are reversed. Fig. 12 (not shown), illustrates the development of the circuit of Fig. 11 wherein each of the inputs to the circuit of Fig. 5 is provided by a circuit similar to the first stage shown in Fig. 11. Fig. 13 shows two circuits each as shown in Fig. 5, followed by an AND circuit composed of emitter followers 150, 152. A second output is provided with two further emitter followers 154, 156 in parallel, respectively, with emitter followers 150, 152.

Abstract: 1,239,797. X-ray fluorescence gauges. MINNESOTA MINING & MFG., CO. Aug.27, 1968 No.40962/68. Heading G1A. The mass per unit areas of an element in a coating the element having an atomic number one or only a few higher than any other excited element in the base or coating, is determined by a non-dispersive X-ray fluorescence gauge using a filter having an absorption edge at a wavelength slightly shorter than an emission wavelength of the coating element, and comparing the output of the gauge with the output corresponding to a reference coating. Examples of coating materials are Zn, Ni and Fe and for a coating of Zn on Cu, a Zn filter is used. The criteria for selecting the filter thickness are discussed. In the measurement of the thickness of a silver coating also containing titanium dioxide, zinc oxide is added to the coating compound and the X-ray generator excitation potential is enough to excite Zn and Ti, but not Ag.

IPC: B21C1/02
Filed: 1967-09-11
Abstract: 1,149,288. Drawing. BLAW-KNOX CO. 11 Sept., 1967 [28 Sept., 1966], No. 41383/67. Heading B3P. An apparatus for drawing rod or tube comprises a capstan 11, Fig. 2, carrying a gripper 15 for gripping the leading end of the rod &c. and a displacer 20 for moving the rod end &c. generally axially into alignment with a guide 17 after a number of turns have been wound on the capstan 11. As shown, straightened rod R is passed through a channel member 29 of a die holder arm 12 pivotable about a horizontal and vertical axis. After passing through die means 13, the rod end is gripped between gripper jaws 52, 53 actuated by an air cylinder 57 and the capstan 11 rotated about its horizontal axis, the arm 12 swinging about the pivot 28 to follow the rod as it is wound on the capstan. The rod is forced axially towards the other end of the capstan to form a single layer of abutting helical turns by an inclined annular plough ring 94, Fig. 4, supported by a disc 95, which rotates in unison with the capstan. After rubber surfaced snubber rolls 19 have been moved by a cylinder 86 to grip the rod about the capstan, a cylinder 69 is actuated to move a pusher arm 64 to contact the gripped rod end. An arm 65 connected to the arm 64 by a spring 74 is also caused to move against the action of a spring-loaded plunger 75 so that a lateral portion 72 on the arm 65 overlies the rod end. The gripper jaws 52, 53 are opened and the pusher arm 64 moved further forward to move the rod end into the opening of the funnelshaped guide 17, further displacement of the arm 65 being prevented by a roller 78 on the plunger 75 abutting a wall 82. Whilst the air pressure in the cylinder 69 is released causing the arms 64, 65 to move back, the rod is fed over a feed roll 22 and deflector roll 23 and into a guide 25, whereupon a feed roll 24 is moved downwards by an air cylinder 135 to positively drive the rod into a straightening unit 4. Finally, the snubber rolls 19 are moved away and the capstan speed increased to full drawing speed. When the rod leaves the payoff reel (2), the snubber rolls 19 are moved inwardly and the capstan speed reduced.
