Abstract: 1,172,309. Nut-runners. PRESSLUFTWERKZEUG-UND MASCHINENBAU " PREMAG" G.m.b.H. 15 March, 1967 [16 March, 1966], No. 12165/67. Heading B3N. Fasteners are tightened by pneumatic nut runners 8 to a precise final tightening torque by first providing a torque whose value is below the final torque, interrupting the tightening during a required time period, and then tightening to the desired torque, during which time the tightening is interrupted for a desired time period. In operation, a manually operated valve 2 is opened and low pressure air flows through a circuit including a distributer 15 and a pressure reducing valve 18, to place a valve 4 in a first position wherein low pressure air flows through a line 6. A valve is also opened in a line 13, and air flows through valves 12, 9, to open an on/off valve 7. Low pressure air is supplied from line 6 to nut runners 8, the fasteners are tightened to a value below the final torque, and the nut runners stop. Back pressure builds up in line 6 until a valve 14 opens, and air is fed through this valve from distributer 15 to open a valve 16. Air at a higher pressure is fed to valve 4 through valves 17, 16 and 19, and simultaneously to a distributer 11, and thence to valve 12 which closes and interrupts the air flow to valve 7, which also closes and prevents air feed to runners 8. Air is also fed from distributer 11 to a normally closed valve 10, which is associated with means for providing a time delay, so that the valve is closed during this time and thereafter opens, and allows air to flow to valve 7, which opens and the runners 8 are driven at the increased torque. This supply of increased torque is interrupted intermittently for given intervals of time by control means associated with valve 10. A preselected number of interruptions may be counted, and valve 2 or valve 7 may be closed automatically.

Title: Improvements in or relating to ticket printing machines
IPC: B41K3/08
Filed: 1944-06-28
Abstract: 595,066. Ticket-printing machines. SETRIGHT REGISTERS, Ltd., TOVEE, H. J., and YAXLEY, J. V. June 28, 1944, No. 12325. [Class 106 (iii)] In a ticket-printing and issuing machine, two pawls 17, 38 provide the interlock between the manually-rotatably actuating-member and the manually-adjustable value printing-wheel, each pawl being arranged to permit or obstruct movement of the other so that the machine can only be operated when the value printing-wheel is set correctly and the setting of the printing- wheel cannot be altered unless the main shaft is in its home position. A ratchet wheel 16 for preventing reversed rotation of the main shaft 11 has an extra deep tooth space 20 to receive the nose of the pivoted pawl 17 when the main shaft is in its home position, the tail 21 of the pawl being then clear of an aperture 22 in a casing partition 23. In any other position of the main shaft the pawl is rocked so as to obstruct the aperture, thereby preventing passage of a lock-bar 41 and movement of a locating-pawl 38 pivoted thereto, with consequent locking of the printing-wheel 32, since a pin 37 on the locating-pawl 38 engages a tooth space in a wheel 36 on the printing-wheel shaft. Should the wheel 32 be incorrectly set, the pin 37 will ride on a tooth of the wheel 36 and the end of the lock-bar 41 will project through the aperture 22 and obstruct the tail 21 of the pawl 17, thus preventing operation of the main shaft to print a ticket. A differential totalizer is operated in known manner from a stepped gear 48 and axially-adjusted pinion 46 set by the shaft 33. Modified arrangements of the pawls are described with or without lockbars, and for one or more value printing-wheels. Printing on a paper strip fed along the line X-X is effected by a platen 28 operated by the sudden release of a spring-pressed cam 30.

In order to prevent aeration of the working liquid in a direct-acting, hydro-pneumatic telescopic shock-absorber means are provided for permitting atmospheric pressure to act upon at least the radially innermost portion of a seal element 15 which is mounted, adjacent a cylinder end cap 11, between a piston-rod 13 and a working cylinder 10, with provision for the entire seal element to slide axially within the cylinder under the resultant of the opposed atmospheric pressure and liquid pressure within the cylinder 10. The seal element 15 has annular lips 22 on its inner surface and a naturally concave surface 23 in axial crosssection which is extended in two resilient annular flanges 24, 25. The end cap 11 is maintained in position by inward peening of the adjacent end of the cylinder 10 and by the engagement of a shoulder 27 on the cylinder wall by a flange 28 on the cap 11. The upper surface of the seal is placed in communication with the atmosphere through an annular groove 30 in the adjacent face of the end cap and through spaced ports 31 in the cap 11. Alternatively, or in addition, passages may be formed by serrations 32 in the inner surface of the cylinder 10. In a modification, Fig. 3 (not shown), the seal (35) instead of being substantially rigid, has a radially intermediate resiliently flexible part (36) which allows the inner portion (37) of the seal to move axially relative to the outer portion (38). The lips 22 are replaced by a single lip (40). In a further modification, Fig. 4 (not shown), the seal (42), substantially the same as the seal 15, has a single lip seal (43) and an outer surface which is not completely flattened, an enlarged guide aperture (14) in the cap (44) providing communication between the atmosphere and a plano-convex space (46) between the cap (44) and the seal (42). In another arrangement, Fig. 5 (not shown), the cap (51) and the seal (50) move together, the cap (51) having its upward movement cushioned by an O-ring (53). Atmospheric pressure may be led to the seal through a cap made of air pervious material.
