Patent GB-1176362-A (GB)
Title: Improvements in or relating to Methods of and Apparatus for Joining Wires
Inventor: BURGESS REGINALD ROBERT
IPC: H01R43/042
Filed: 1967-03-22
Abstract: 1,176,362. Making electrical connections; angular bending; jointing; shearing. POSTMASTER GENERAL. 14 March, 1968 [22 March, 1967], No. 13600/67. Headings B3A, B3E, B3Q, B3V and B3W. [Also in Division H2] A method of joining together first and second lengths of insulated wire comprises placing the first and second wires into and along the length of a metallic clip of trough-like form so that the free ends of the wires extend beyond opposed ends of the clip, cutting off the free ends of the wires and deforming the clip to grip the first and second wires, the clip having integeral insulation piercing means which make electrical contact with the wire through the insulation. The clips are stored in a spring-loaded magazine 13 and retained in the operating position against the action of the spring by projections 25, 26. The wires to be joined are laid in the clip in a crossed formation, the positioning of these wires being facilitated by vertical separators (29a), (29b), Fig. 7 (not shown), at each side of the clip which define V-slots 30, 31, the free ends of the wires being placed in the deeper slot 31. The operator holds the free end of each wire and he then depresses a foot pedal which is connected to a punch 16 by a cable to move the punch towards a die 15. A blade 18 separates the top clip from the rest in the magazine, the clips being held together adhesively. Further movement of the punch causes spring-loaded notched heads 21 to engage the wires and tension them against the pull of the operator. When fully tensioned knives 19 cut off the free ends of the wires and the heads 21 spring forward pulling the ends of the wires inside the clip. As the ends of the wire are being drawn into the clip it is crimped by the punch 16 against the die 15. Another type of machine is provided with a horizontal magazine (13), Fig. 11 (not shown), and has a foot-operated Bowden cable 28 actuating a pair of beaked jaws 34, 35 via a series of lever arms. Depression of the foot pedal causes a member 40 to break the adhesive joining the end clip and lifts it to the operating position. Wires are placed one on each side of vertical separators (38), (39), Fig. 11 (not shown). Further depression of the pedal allows blades attached to the jaws to cut off the free ends of the wires prior to crimping, the jaws folding over the sides of the clip and finally clamping home the edges over the wires. The wires are individually crimped by each side of the clip, Fig. 4 (not shown). In a third form of connector, the wires are laid in the clip which is then closed between flat jaws. The remounted ends are cut off by cutting edges 12. The connectors, which may be of hard brass or phosphor bronze, are mounted end to end on a strip of insulating material prior to use.

Title: Process and apparatus for improving the qualities of sheet metal, more especially sheet metal for use in electrical equipment
IPC: C21D8/12
Filed: 1956-05-03
Abstract: 833,487. Annealing. SCHLIEKER, W. H., [trading as WALZWERKE NEVIGES, W. H. SCHLIEKER & CO.]. May 3, 1956 [May 3, 1955], No. 13719/56. Class 72 [Also in Group XXII] A process for improving sheets of ferromagnetic material is characterized in that the sheets are passed through finishing rolls and thence directly through a zone in which they are subjected to a thermal treatment including a progressive cooling through a range of temperatures in the region of the Curie points, and in which, at least during the said cooling, they are subjected to the influence of a magnetic field. In an embodiment the sheet metal is passed through rolls A, then through an electrical heat treatment furnace B and finally through a cooling zone C. The sheet metal is preferably hot rolled or alternatively hot and cold rolled. In the cooling zone C a magnetizing section M is provided and comprises a coil 1 surrounded by heating or cooling tubes 3. Alternatively a cooling medium may be passed through part of the magnetizing coil which is extended to 1<SP>1</SP> to provide the cooling portion. Various lengths of the coil may be operated as the magnetizing section if desired. Preferably the magnetizing section is maintained under a protective gas. The sheet metal may be supported on rollers or an endless conveyer belt as it passes through the magnetizing section. The magnetizing coil may be arranged to give various directions of the field strength vector H relative to the direction of travel t of the sheet metal (Figs. 4, 5 and 6). In a modification two. coils 71 operated with direct current are used to prevent excessive voltage differences between the ends of the coil. Themagnetic field may be generated by permanent magnets or coils operated with different current strengths or different types of current may be combined. Afterthe sheet metal has been rolled, heat treated, subjected to magnetization and. in cases where the sheets have been joined into strip, after being separated again into individual sheets, the sheets are passed in quick succession through a device which weighs and measures the electrical properties of each sheet. If such properties differ from a predetermined standard a signal is given to the machine operator so that he can readjust or regulate the magnetic field strength or the temperature in the magnetizing section of the cooling zone.

Abstract: 863,813. Electromagnetic relays. SPEED DEVELOPMENT CO. Ltd. Sept. 25, 1957 [May 1, 1957], No. 13890/57. Class 38 (5). [Also in Group XXXVIII] A temperature alarm system (see Group XXXVIII) incorporates a polarity sensitive relay having a first coil MR1 actuated by a control signal and making contacts 10, 12 whereupon the charging current of C passes through MR2 to increase the contact pressure. The relay coil M of a main relay then operates and closes 17, thus a reverse current flows through MR2 and opens 10, 12. A pulsating action is thus established which continues as long as a control current is passing through MR1. The switch 17 also energizes a solenoid L which projects a re-set contact 20 into the path of the movable contact 10 for contact therewith when the current through MR1 ceases. The consequent opening of M retracts this re-set contact. Specifications 687,136, 817,258 and 817,259 are referred to.

Abstract: 436,134. Making economizer tubes. INTERNATIONAL COMBUSTION, Ltd., Aldwych House, Aldwych, London, and DEVLIN, S. R., 9, Buller Street, Derby. May 16, 1935, No. 14370. [Classes 83 (ii) and 83 (iv)] Jointing.-In a machine for making gilled tubes for economizers &c. short gilled sleeves are heated and drawn on to a cooled tube, means being provided for ensuring that the gills occupy the same relative positions on each tube. The machine comprises a frame 1 supporting a railplate 2 on which runs a carriage 3 mounted on wheels 15. Ropes 4, 5 are attached to opposite ends of the carriage and are wound on drums 8, 9 driven by an electric motor 11 through gearing and a slipping clutch 10. A drawplate 18, Fig. 4, is pivoted to the carriage and carries a roller 19 engaging a ramp 20 at the right-hand end of the machine in order to lift the plate over a gilled sleeve placed upon the rail-plate 2. A tube 22 is clamped at 23 on the machine and the carriage is run by the ropes 4, 5, to the right-hand end of the machine to engage a heated sleeve 21. The motor 11 is then reversed and the sleeve is drawn over the tube, the first sleeve being placed at the lefthand end of the tube and the subsequent ones at adjacent positions. A gauge plate 35, Fig. 2, carrying points 36 corresponding to the required pitch of the gills is pivoted at the side of the machine and is used by the operator for testing the positions of the sleeves. The motor is controlled in direction and speed of rotation by a rod 14 extending along the machine and limit switches 12, 13. Spring buffers 37 are provided at opposite ends of the machine for engagement by the carriage. Instead of the gauge 35, or in addition thereto, a gauge plate (not shown), may be provided on the carriage for engagement with each sleeve carried thereby and also with the gills of the last sleeve added to the tube 22, the clutch 10 then slipping until the motor has been reversed. The tube 22 is supported at intermediate points by a number of arms 25, Fig. 5, held in the vertical position shown by means of springs 29 and weights 31. As the carriage is traversed along the tube, a curved member 28 thereon engages in turn with rollers 27 carried by arms 26 attached to the arms 25, whereby the arms 25 are tilted to the dotted position shown in Fig. 5 to allow the sleeve on the carriage to pass. If a sleeve should be drawn too far along the tube, a draw-plate 17, Fig. 4, on the carriage may be lowered to engage the opposite end of the sleeve to retract it to the correct position. The tube 22 is kept cool by water, air or other fluid supplied to the clamped end 23 thereof from a tank 33, the fluid issuing from a nipple 32 attached to the free end of the tube and running to waste or being re-circulated.
