Abstract: 1343084 Printing machines OCE-VAN DER GRINTEN NV 6 July 1971 [16 July 1970] 31718/71 Heading B6C A cylinder carrying a sheet 8 to be printed or a master sheet or plate from which copies are to be printed has means for clamping the leading edge of the sheet 8 comprising a gripper bar 4 which receives the sheet edge as shown in Fig. 1, and is moved inwardly of the cylinder to grip the sheet edge, and subsequently, to release the sheet, is moved further inwardly beyond the sheet edge, Fig. 3, and then moved outwardly to eject the sheet. The outer end of the bar 4 is shaped as shown so that the sheet edge is bent inwardly and clamped against the edge of an axial slot in the cylinder, the inwardly bent part springing away from the slot edge as shown in Fig. 3 when the bar 5 moves further inwardly so that during subsequent outward movement of the bar 5 the bent part is ejected from the slot. The cylinder comprises a cylindrical casing 1 and end discs 2. The bar 4 slides radially in slots 3 in the discs and has followers 5 engaging cam tracks 6 to cause the required movement. The sliding movement of the bar 4 may be other than radial (Fig. 5) or the bar may have a pivotal movement (Fig. 6). As shown in Fig. 7, the bar 4 mounted on the cylinder 1 as in Figs. 1, 3 has a rod 15 at its ends projecting through a slot in gear 14 for the cylinders, the rod 15 being subject to the action of springs 28 so as to cause cam follower roller 16 on the rod to engage a cam 18 which operates the bar as described above. A second cam 19 is fixed to the cam 18 and the two cams are moved axially of the cylinder 1 by a spring 22 when a solenoid 27 is de-energized so that the follower 16 engages the cam 19. The latter is circular and dimensioned so that when operative, the bar 4 is permanently held in the clamping position.

Patent GB-348087-A (GB)
IPC: G01F15/18
Filed: 1929-10-29
Abstract: 348,087. Preventing unauthorized use of motor vehicles. SOC. LIBER, 55, Rue de Rivoli, Paris. Oct. 29, 1929, No. 32,833. Convention date, Oct. 30, 1928. Void [Published under Sect. 91 of the Acts]. [Class 79 (iii).] Lockable means, (not shown), for preventing the engine of a motor vehicle from being started up, by closing the induction pipe, opening an electric circuit, &c., also actuate means which are optionally effective to cause a radially slidable bolt 5 to lock the steering wheel shaft 9 within its supporting pillar 8. For this purpose, a cam plate 1, which is rotated with the locking means putting the engine out of use, operates, by means of a groove 2, a plunger 4 slidable within the bolt 5, thereby compressing a spring 12 by which the bolt 5 is actuated. Rotary adjustment of a pin 11, passing transversely through slots in the plunger, bolt and the enclosing casing 6 and retained in either of two positions at right-angles by a cross-bar 13 adapted to engage grooves 14 in the casing, determines whether or not the bolt 5 is free to engage a recess in the shaft 9 when the spring 12 is compressed. This effect is obtained by the co-operation of flats 19, 20 in planes at right-angles on the parts of the pin 11 passing through the plunger 4 and the upper part of the casing 6, where the slots are of key-hole formation pointing in opposite directions, as shown in Figs. 2 and 3. Figs. 1 to 3 show the conditions under which the pin is free to move with the plunger and does not oppose actuation of the bolt 5. If turned through a right-angle, however, the rearrangement of the flats 19, 20 in the key-hole slots, obstructs movement of the pin 11 and thereby, of the bolt 5, though still allowing movement of the plunger 4. Rotation of the pin is only possible in the initial position before the plunger is actuated. A modified form of pin, with the cross-bar 13 incorporated in a spring-pressed head, is described.

Abstract: 783,149. Phase measurement. SPERRY RAND CORPORATION. Nov. 18, 1955 [Nov. 26, 1954], No. 33039/55. Class 37. [Also in Group XXXV] In apparatus for measuring the difference in phase between two voltage pulses, the two pulses from source 30 are made to appear at 28, 29 on the screen of a cathode-ray oscillograph 26, where they are compared with two reference pulses 31, 32 derived from the pulse generators 23, 24 connected respectively to input and output windings of a phase shifter 14. The cathoderay sweep is produced by a sawtooth wave voltage from generator 25 fed from pulse generator 23. The phase shifter is energized from an oscillator 11 which is tuned so that the repetition rate of pulses 28, 29 and of reference pulses 31, 32 is the same and that pulses 28 and 31 are coincident. The phase shift between reference pulses 31, 32 is altered by rotating knob 21 on phase shifter 14 until pulses 29, 32 are coincident, when the angle through which knob 21 has been turned is a measure of the phase angle between reference pulses 31, 32 and therefore between pulses 28, 29. The phase shifter 14 comprises an input winding 13 inductively coupled to two windings 15, 16 in quadrature from which the output is obtained through a phase shift circuit comprising resistor 18 and capacitor 19. Rotation of the input or output windings (as shown) by knob 21 changes the phase of the output. The input reference pulse is derived from a winding 22 tightly coupled to winding 13 and not to the latter winding, whereby the phase shift is made independent of temperature.
