Title: Improvements in apparatus for cancelling single and multi-journey tickets
Inventor: PRUMM GEORG
IPC: G07B11/03
Filed: 1966-08-30
Abstract: 1,162,383. Cancelling tickets. G. PRœMM. 30 Aug., 1966 [28 Aug., 1965], No. 38696/66. Heading G4T. A device for cancelling tickets has a microswitch 13 and release switch 12 connected in the cancelling mechanism circuit, whereby both switches are closed only if the ticket is correctly positioned in the device to actuate the cancelling mechanism. When actuated, the cancelling mechanism which comprises a punching knife and a printing stamp, is caused to move vertically downwards by an electromagnet, to print a cancelling mark on to, and possibly cut a notch into, the ticket. In one embodiment, as shown, separate cancelling mechanism actuating microswitches are provided for " single " and " multi-journey " tickets, a narrow " single " ticket being urged to the left of a guide channel by a lever 35, to close series-connected microswitches 13 and 14 to actuate the printing stamp. A wider, multi-journey ticket, as shown, whose edge has had several notches removed, is sufficiently wide to urge lever 35 against a third microswitch 9 to disable micro-switch 14. The cancelling mechanism will then only be activated if both microswitches 13 and 12 are closed, i.e. only if the " multi-journey " ticket is correctly orientated, with its next portion to be notched abutting a stop 32. If a " single " ticket is urged against lever 35, the ticket is sufficiently narrow to leave switch 13 open and prevent cancelling. In a second embodiment (Fig. 3, not shown) the two forms of ticket have the same cancelling mechanism activating switch (12) the tickets in this case being of the same width. In this case the switch 13 will only deactivate the cancelling mechanism activating switch 12 if a multi-journey ticket is wongly inserted (Fig. 4, not shown).

Filed: 1972-08-22
Abstract: 1379834 Rolling mills INSTITUT CHERNOI METALLURGII 22 Aug 1972 39037/72 Heading B3M A billet turning mechanism for a tube cold rolling mill includes jaws 6 carried in a rotatable spindle 3, the jaws being movable radially by axially displaceable wedges 12 to positions in which they grip or release a billet 7. The spindle is mounted in a stationary housing 1 and is rotated, together with the jaws 6 and a plate 13, by a gear 4. Wedges 12 are carried by the plate and co-operate with pairs of inclined surfaces on adjacent jaws, such that axial movement of the plate 13 towards the spindle causes the jaws to be wedged apart and the billet to be released. The plate is shifted axially by rollers on the plate which co-operate with a non-rotatable cam disc 17. The form of the cam disc can cause the jaws to grip and turn the billet either once or twice for each rotation of the spindle. Two or three shoes may be carried in a holder 10, Fig. 4, spacers 25 between the halves of the holder being interchangeable to vary the force exerted by the jaws on a billet. To take up wear in the mechanism, the cam disc 17 is axially movable towards the rollers. To this end, the disc is carried on a splined member 18 having a threaded extension 21 at one end. The extension co-operates with a gear 22 which is rotatable by an adjusting pinion 24.

Title: Improved hydraulic means for stressing the springs of spring-actuated electric switches
IPC: F15B21/00
Filed: 1959-11-20
Abstract: 889,248. Hydraulic actuation of switches. ALLMANNA SVENSKA ELEKTRISKA A.B. Nov. 20, 1959 [Nov. 22, 1958; Dec. 18, 1958], No. 39387/59. Class 38 (5). The actuating spring 12 of a high-voltage switch is stressed by means of a piston 17 connected through a pipe 7 to an assembly comprising a liquid container 1, a valve housing 4 and a pump 2 driven by a motor 10 supplied through a control switch 8. Movement of a member 18 releases an arm 11, which is rotated anti-clockwise by the spring 12 to close the switch and to release a locking member 13 from engagement with the piston rod, movement of the member 13 thereby closing contacts 14. This closure operates the switch 8 which is held closed by its contact d to start the pump 2, the resulting liquid flow from the container 1 depressing a valve 3 against the housing 4 and then passing through a spring-loaded ball valve into the pipe 7 and the cylinder 15. The piston is thus lifted to restore the arm 11, the switch 8 being held closed upon release of the member 13 by a pressure switch 6 until members 11, 12 are fully reset, after which the system pressure rises to open the switch 6 and stop the pump 2. Restoration of the piston 17 by a spring 16 reengages the member 13 and forces liquid back into the container 1, a valve 9 serving to release excess system pressure. In a modification, Fig. 4, the arm 11 is connected to an extension of the member 13 by a spring 21, member 13 being rotated anti-clockwise from engagement with the piston projection 19 by downward movement of the arm 11, which is restored by an arm 20 secured to the piston 17. If, however, downward movement of the arm 11 occurs when the piston 17 is under downward liquid pressure caused by operation of the piston associated with another switch, the projection 19 prevents release of the member 13 by the spring 21 until such an operation is completed, thus ensuring that the pump 2 is not overloaded,
