Title: An improved screwing die-head and a method for cutting screw-threads therewith
IPC: B23G1/22
Filed: 1968-06-28
Abstract: A die head for cutting a taper screw thread on the end of a pipe 1 comprises a rotatable body 15 carrying radially-disposed die members 24, a sleeve 2 having an external screw thread 12 of the same pitch as that to be formed on the pipe engaged with an internal screw thread 13a in a lead nut 13 secured to the body 15, a slipclutch 52 for disengageably coupling the sleeve 2 and body 15 for conjoint rotation, and a mandrel 4a, 4b which is axially displaceable in the sleeve 2 by means of interengaging screw threads 5, 50 and has an end which projects from the sleeve for insertion in the pipe 1 and is formed with inclined grooves 7 for radially displacing three wedges 8 located around the mandrel end into clamping engagement with the interior of the pipe 1 to secure the die head thereto. A die adjusting sleeve 20 rotatable with the body 15 has an inclined nose 27 engaging grooves 26 in the die member 24 and is in screw-threaded engagement with a thread 19 of greater pitch than the threads 5, 50 on a ring 17 which is connected to the sleeve 2 by a spigot screw 16 engaging a slot 40 so as not to rotaterelative to the sleeve but to be capable of limited axial movement resisted by a brake spring 36. The slip-clutch 52 couples a clutch ring 54 which is positively driven through a ratchet 51 when the body 15 is rotated in the thread-cutting direction to a coupling sleeve 55 which is adjustably secured to the sleeve 2 by a claw ring 53 and a nut 57 permitting adjustment of the thread diameter. In operation, the pipe 1 or the mandrel 4a, 4b is held fast and either the mandrel inserted in the pipe or the pipe fitted over the mandrel, and the body 1 is rotated manually by a hand crank or ratchet or is motor-driven through reversing gear engaged with a claw ring 56 on the body. Initial rotation of the body 15 is transmitted through the slipclutch 52 to rotate the sleeve 2 on the mandrel and tighten the wedges 8, but when the clamping torque attains a set value the clutch 52 slips and after one revolution of the body on the sleeve the ratchet 51 disengages from the clutch ring 54. The body 15 then advances along the sleeve 2, the die adjusting sleeve 20 being advanced more rapidly than the body by the thread 19 so that the die members 24 are progressively moved outwards to form the tapered thread. When the thread is complete the lead nut 13 abuts the end of the ring 17 which is axially displaced together with the die adjusting ring 20 to disengage the die members 24 from the thread.

Abstract: Apparatus for trimming and electrically connecting the ends of wires comprises, a connector crimping die 82, 84 and a crimping anvil 62, 64, means for moving the die and the anvil relatively towards and away from one another, means 90, 901 to co-operate with the die for trimming the wire ends during initial relative movement of the die and anvil towards one another, and a wire positioning device, 126, 1261 disposed on each side of the anvil, each device 126, 1261 being adapted to hold one of the wires, move the wire end when trimmed towards the anvil and position the trimmed wire end in a substantially U-section uncrimped electrical connector 14 supported on the anvil. Wires 6, 8 of a twisted pair 2 are laced through the device 126, then led through notches 96, 98 in the shear member 90, through the cavities of dies 82, 84 and through a gap 45a between bosses 45 of a frame 44. The wires 10, 12 of a second pair 4 are similarly led from the device 1261 to the gap 45a. A handle (52) is rotated through a complete revolution to cause plates 32, 34 to move downwardly and then upwardly, Fig. 2 (not shown). During the initial part of their downward movement, die blocks 58, 60 are swung about pins 66, 68 by the action of cam rollers 70, 701 on cam surfaces 74, 741. The members 90, 901 are moved relatively downwardly along surfaces 67, 69 by bell-cranks 108 as the die blocks swing towards each other, thereby trimming the ends of the wires and leaving them projecting obliquely into the cavities of the dies 82, 84, Fig. 5. Further movement of the plates 33, 34 causes relative upward movement of an arm 78, which engages fingers 140 thereby rotating the positioning devices 126, 1261 and the wire ends upwardly to place them in connectors 14, which are held by clips 63. At the end of the downward stroke of the plates 33, 34, the dies 82, 84 bend over the upstanding side walls of the connectors thereby securing the wires in pairs of aligned slots 22 in the connectors, the edges of the slots penetrating the wire insulation to establish electrical contact, Fig. 17 (not shown). The plates 32, 34 are then returned to their initial positions and the crimped connectors removed from the clips 63. The plates are returned either by return springs (not shown) or by an arrangement of cams as described in Specification 1,176,104.

Title: Improvements in or relating to methods of manufacturing components employing a high-energy beam of electromagnetic radiation
IPC: B23K26/14
Filed: 1969-11-29
Abstract: A method of manufacturing components e.g. resistors, thin film circuits and capacitors, comprises providing a carrier body with an overall layer of a material and a further coating having a non-reflective characteristic with respect to a beam of electromagnetic radiation which is used to burn off required areas of the layer of material, the coating having a thickness equal to or an odd multiple of d, where d is defined by the equation n.d= #/4 and n is the refractive index of the coating material at the wavelength # of the radiation used. A cylindrical ceramic body 1 has a carbon layer 2 and a varnish coating 3. A laser beam is focused to a point 8 on the carbon, the component body being rotated and moved axially so that a helical groove 9 is burned into the carbon. An air blast from nozzle 10 blows the molten parts of the component away from the point of burning. The coating 3 reduces the reflection of the radiation and thus accelerates the burning process. Chrome/nickel is a suggested alternative to carbon, and the coating may be of a solid fluorohydrocarbon or a phenolic resin polyesterimide varnish. The method may be used for metal, metal oxide, metal glaze layers and thin and transparent non-metal layers, e.g. of an insulating type.
