Title: Resistance welding machine
IPC: B23K11/16
Filed: 1972-03-14
Abstract: 1386105 Resistance welding ACCRA-POINT ARRAYS 14 March 1972 11730/72 Head ing B3R In a resistance welding machine for welding an insulated wire 55 to a terminal element 57, a first electrode 54 is carried by a first carriage 31 movable relative to a base 11 on which there is a second electrode 22. A second carriage 32 is initially connected to the first carriage by magnetic attracting means, such as permanent magnet 44 on the second carriage and magnetic bar 46 on the first, and is moved by means such as air pressure-actuated piston 13 or a foot pedal mechanism (71-82, Fig. 2, not shown) so that the carriages move as a single unit into a welding position in which the first electrode 54 is urged into contact with the stationary element 57 which is in contact with the second electrode 22. The force exerted by said moving means (piston 13) is such that it breaks the insulation on the wire 55 but then overcomes the magnetic attraction between the carriages and the two separate. However, a spring, e.g. constant force spring 43, Fig. 1, or conventional extension spring 85, Fig. 3, provides a force of attraction between the two separated carriages which is less than the connecting force of the magnetic attracting means. Means for supplying the electrodes with current to make the weld under the pressure exerted by the spring, may include a switch 25, 26 actuated by the second carriage, or a switch 92, Fig. 3, actuated by an adjustable set screw 91 mounted on the carriage. In Fig. 2, the travel of the second carriage is limited by another adjustable set screw 88, the force exerted by extension spring 85 being dependent on the length of travel of the second carriage 32 after the first carriage has been stopped by engagement of the electrode 54 and wire 55 with the terminal 57. Dashpots 66, 65, Fig. 1, may be provided to absorb movement transients when the magnetic attraction is broken.

Abstract: 913,083. Coated fabrics. HARDURA GROUP Ltd. July 3, 1961 [April 5, 1960], No. 11929/60. Class 140. Random patterned thermoplastic sheet material suitable for use as a floor covering is produced by depositing controlled amounts of thermoplastic granular or like particulate material on to a moving belt from which they are then deposited into the path of an impeller or beater which scatters them against a deflector plate from which they fall on to the thermoplastic sheet material to be patterned, said sheet material having previously been softened by heating, and the scattered particles then being softened and pressed down into said material to leave a plane top surface. The thermoplastic sheet material may be in long lengths, and may be a coated hessian, felt or other textile base, or a film or a pellicle. A coated base material, the coating being in a softened state, may be passed below a deflector plate to receive a continuously-falling curtain of granules or particles in their random arrangement, the coated material with the particles or granules thereon then travelling into a heater whereby both coating and particles or granules are softened prior to the application of pressure so as to spread the softened particles or granules whilst at the same time pressing them into the coating. Apparatus for producing the sheet material includes a pellet scattering device comprising one or more feed hoppers 7 arranged across the direction of feed of the coated base material 1 with controlled delivery means operative along the length of each hopper; a slowly-moving endless conveyer 5, below the hopper or hoppers, receiving the particulate material deposited by such means; a high-speed rotary impeller or beater 15 adjacent the delivery end of the conveyer receiving the particulate material as it falls off the end of the conveyer, a deflector plate 16 against which the falling material is thrown by the beater; and means for passing the coated web 1 below the deflector plate to receive the dispersed granules as they fall back from the deflector. The apparatus may comprise a first hopper 7 for larger granules with control means for effecting a slow rate of exit, and one or more smaller hoppers 11 for smaller granules, each with a control means for effecting a more rapid rate of exit, the arrangement being such that first the larger granules are deposited on to the slowly-moving conveyer and then the smaller granules are deposited so as to mix with the already deposited larger ones.
