Title: Improvements in and relating to automatic lathes
IPC: B23B13/00
Filed: 1962-11-30
Abstract: 979,840. Lathes. E. C. HAHN, [trading as INDEX-WERKE KOMM. GES. HAHN & TESSKY]. Nov. 30, 1962 [Nov. 30, 1961], No. 45503/62. Headings B3B and B3T. [Also in Division B8] An automatic single spindle lathe comprises chucking mechanism to pick up a workpiece and move it forwardly within a headstock and two switches, one, 198, (at the rear of the headstock) actuated to stop the machining as the mechanism is retracted and the other, 196, Fig. 2 (at the front of the headstock) actuated to restart the machining as the mechanism is advanced. The chuck 30 is operated by a collet sleeve 32, a lever 34 and a cam 36 controlled by a rapid action clutch 60. The spindle-22 is rotated by a motor 24 which also rotates a shaft 42 connected by an electric clutch 44 to a shaft 46 providing drive for indexing the turret &c. and for rotating a shaft 50 driving cams for feeding slides 38, 40 and a cam drum 52 carrying dogs 54 for actuating switches for gear-shifting &c. and for controlling a lever 58. When the lever 58 is struck by a dog 54, the member 70 of the clutch 60 is engaged to rotate the collet-operating cam 36 by 180 degrees to unclamp the workpiece; as the clutch continues to rotate, a cam surface 78 on a part of the clutch member 70 withdraws the clutch to a non-driving position where a catch 76 is engaged. In operation, a push-button is depressed to actuate a valve 136 to cause a rod 160 to be advanced by fluidpressure in a cylinder 150 and feed a workpiece 94, Fig. 3, from a double-armed segmental member 104, through the lathe spindle and up to a stop 190 on the turret 18. The stop 190 moves to actuate a switch 196 which energizes the clutch 44 and causes the drum 52 to rotate, thus actuating the clutch 60 and closing the collet through the lever 34. Movement of the lever 34 actuates the switch 198 to cut off pressure from the work-feed rod 160. When machining is complete, a further cam on the drum 52 actuates the clutch 30, causing release of the switch 198 and withdrawal of the rod 160 which, by means of a gripper head 160 carries the work with it. When the head 166 abuts the end of the cylinder 150 the work is released; at the same time, the end of the rod 168 abuts a switch 174 and actuates a valve 138 not only to move a piston 116, Fig. 3, upwardly to pivot the member 104 and deposit the workpiece into a bin 200, but also to allow a piston 120 to move downwardly. Movement of the member 104 actuates a switch causing the member 104 to be moved back to the position shown in Fig. 5 to receive a new workpiece. A timer then operates and, subsequently, the valve 138 is actuated to move the new workpiece to the starting position of Fig. 3. In a modification, bar stock 28, Fig. 2, is supplied. When the head 158 of the piston 160 engages a switch 210, the stock remaining in the spindle is withdrawn as scrap and a new bar is supplied. In a further modification, work is released from the magazine 90, 92, Fig. 3, by magnetically-controlled grippers.

Filed: 1975-11-11
Abstract: 1531465 Disconnectible pipe couplings COMPAGNIE MARITIME D'EXPERTISE 11 Nov 1975 [18 Nov 1974] 46589/75 Heading F2G A pipe coupling, e.g. for connecting the end of an underwater pipeline to the end 2 of an underwater well-head, comprises half unions 7, 8 joined by an arrangement that enables them to be telescoped to vary the overall union length, each half union 7, 8 carrying a jaw mechanism operable to either grip or be forced to release grip of the respective pipe ends 1, 2, the telescoping of the half unions 7, 8 and the operation of the jaw mechanisms being carried out under remote control. The telescoping and the jaw operation are both provided by a mechanism that converts the rotation of a nut 17, 9, 38 threaded on the half union body 19, 40 into axial movement of an associated sleeve 16, 37 or of the other half union 19, friction washers 21a, 21b, 48a, 48b, providing the connection. Jaw mechanism.-Two types of jaw mechanism are described, one for use with a smooth pipe end, e.g. 1, and one for use in a pipe end having preformed grooves 4a, 4b, e.g. a bush 4 welded to the end of the pipe 2. In both cases the jaws 10, 17 are forced to grip the pipe end on movement in one direction of the corresponding sleeve 16, 37 by the interaction of conical surfaces 12, 11a, 11b on the jaws 10, 11 and corresponding conical surfaces 13 on the inside of the sleeves 16, 37. Release of the jaws 10, 11 is produced by movement of the corresponding sleeve 16, 37 in the opposite direction, in which case further conical surfaces 24a, 25a, 11c, 11d on the jaws engage corresponding surfaces 26a, 27a, 37a, 36a on the sleeve to produce the loosening. The jaws 10, 11 comprise sectors having longitudinal slots housing elastic rods 33, 35 to keep the sectors equidistant. The jaw mechanism for use with a smooth pipe has ridged 23 jaws and is also self-tightening by virtue of a clearance between a groove 31 in the sleeve 16 and a rib 32 on the jaws 10. In this case the elastic rods 33 also urge the jaws 10 into contact with the end 19a of the sleeve 16. A seal 29 is compressed by the sleeve 16 on tightening the jaws 10. The jaw mechanism for a grooved pipe has ribbed 5a, 5b jaws corresponding to grooves 42a, 42b in the pipe and ribs 41a, 41b corresponding to grooves 42a, 42b in the sleeve 38, the latter ribs and grooves being inclined to the pipe axis to produce compression of a seal 43. The nuts 17, 9, 38 each carry a tooth gear 20, 50, 38a for engagement by a rack on a separate device clamped to the coupling to enable remote control of the coupling. Seals 28a, 28b, 44a, 44b are also provided on the jaw mechanisms and between the half unions 7, 8 respectively. A cylindrical skirt 46 provides a smooth transition between the half unions 7, 8. Sea water is removed from the completed joint by injecting oil through orifices 75, 76.

Abstract: 1,084,879. Directly heated thermistors. TOA ELECTRONICS Ltd. Nov. 4, 1965 [Nov. 7, 1964], No. 46791/65. Heading H1K. The voltage-current characteristic of a directly heated thermistor is rendered substantially independent of ambient temperature over part of the working range by sealing it in a vessel containing a substance adsorbed on its walls. The substance is chosen so that its vapour pressure increases with rising ambient temperature to such an extent that the reduction in heat loss by direct radiation and conduction along the lead wires is offset by a corresponding increase in heat loss-through the vapour. In the embodiment the thermistor is of vanadium glass and has platinum electrodes attached to Dumet leads. The adsorbed substance, water, is introduced into the glass vessel enclosing it by first evacuating at elevated temperature, introducing the water in the form of humid air and then evacuating to a desired degree of vacuum.
