Abstract: 1,179,426. Change-speed control. CLAYTON DEWANDRE CO. Ltd. 16 April, 1968 [20 April, 1967], No. 18278/67. Heading F2D. A vehicle change-speed gear control comprises a shift-lever 10 mounted on a pin 11 in an inverted trunnion 12 and movable along a gate 9 to pivot the trunnion 12 about pins 13, 14 so that cams 21, 22 on the trunnion co-operate with pistons 15, 16 through rollers 19 to open valves 25, 26 to direct compressed air to a gear selector motor (50), Fig. 5 (not shown), the lever 10 being also pivotable about the pin 11 to move across the gate 9 to rock a hollow shaft 35 carrying arms 64 co-operating with pistons (65), Fig. 4 (not shown), to open valves (66) to direct compressed air to a gear shift motor (70), Fig. 6 (not shown), such rocking of the shaft 35 being prevented by pistons (41), (42), Fig. 3 (not shown), co-operating with lugs (38), (39), on the shaft (35) until the compressed air operated main clutch is disengaged, when the pistons are withdrawn. As shown, the control is for an eight forward speed and reverse gear, and a third piston 17 is controlled by a cam 23 to open a valve 27 to direct compressed air to a dual-range cylinder (not further described), to obtain the top four ratios. A fourth spring loaded piston 18 co-operating with cam 24 provides a delay between selection of fourth and fifth gears. A collar 77 or lever 10 must be raised to avoid a baulk on the gate 9 to obtain reverse. A further pair of arms (67), Fig. 4 (not shown), on shaft 35 co-operate with a pair of pistons (68) loaded upwards against the arms by springs and by air pressure communicated through one-way valves (71), (72) in the shift motor (70) from the pistons (66). Rocking of shaft 35, after the clutch is disengaged, is therefore resisted by springs and air pressure until the split piston (73), (74) in the shift motor reaches either of its end positions, i.e. the gear is engaged, when it abuts and opens the respective one-way valve to release the air pressure acting on the respective piston (68) to allow the other piston (68) to hold the lever 10 in its engaged position.

Abstract: 1,007,932. Selective signalling systems. VENNER Ltd. April 24, 1962 [April 28, 1961], No. 15547/61. Heading G4H. The output of a counter is displayed by a moving-coil meter having a scale 18 and means to lock the coil in any of its display positions while a counting operation is taking place. The moving coil 4 carries a disc 20 having teeth 22 which pass through the air gap of a C-shaped permanent magnet 24, the magnetic attraction between a tooth 22 and magnet 24 ensuring that a digit on scale 18 is correctly displayed. Several alternative methods of ensuring correct positioning are described, for example disc 20 may have a single radially extending arm which co-operates with a toothed magnet, Fig. 4 (not shown), or disc 20 may act as the magnet, or magnet 24 may be an electromagnet. Several methods of locking coil 4 are also described. When magnet 24 is a permanent magnet, it may be provided with a winding which is energized during a counting operation to increase the attraction between a tooth 22 and magnet 24 to such an extent that the maximum torque which coil 4 can exert is not sufficient to overcome the attraction. A more economic method is to make the. attraction between magnet 24 and teeth 22 large enough to prevent movement of coil 4, and to energize a winding on magnet 24 to reduce the attraction for a short period after a counting operation. Fig. 7 shows a pawl-and-ratchet type of arrangement in which a disc 25 carried by coil 4 is simultaneously positioned to display the correct digit and locked in that position as pawl 27 engages an indentation 26. Another mechanical locking arrangement which may be used with any of the magnetic positioning arrangements described comprises a solenoid-releasable friction pad engaging disc 20. The digits on scale 18 may be optically projected.

IPC: B65H1/18
Abstract: 1,052,918. Feeding and delivering sheets. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. April 17, 1964 [April 19, 1963], No. 16126/64. Headings B6B and B6H. In a sheet processing machine wherein sheets are delivered to a pile or removed therefrom one by one, the height of the pile is kept substantially constant under the control of a feeler 3 which is secured to the shaft of a rotatable magnet 1 suspended by an adjustable mounting 2, the magnet and feeler being rocked between operative and inoperative positions B and A, respectively, by a switch 6 controlled by a cam 5 which is rotated in synchronism with the machine. As applied to the delivery of sheets to form a pile 10, in each cycle of the machine the cam 5 first closes contacts 7 of the switch 6 to cause the magnet 1 to rock the feeler 3 from position A to position B where it engages the top of the pile 10, and after a delay, the cam closes pile motor contacts 8 of the switch. If the pile is substantially below a datum height 11, the feeler 3 engages and opens a switch 9, so that the circuit between the contacts 8 and a motor which drives the table supporting the pile is broken. If, however, the pile is at, or above, the height 11, the switch 9 is not opened by the feeler 3, and the motor is operated to lower the pile table for a period of time governed by a time switch in the motor circuit. A pressbutton switch in series with the switch 9 enables the pile table to be raised during the working of the machine, but only when the feeler 3 is in the position B, so that the pile height can be raised in timed steps to the height 11. When the machine is stopped, a further contact in the press-button causes the contacts 7 to be bridged to energize the magnet 1 and hold the feeler 3 in the position B, so that uninterrupted raising of the pile table is possible until the pile is at the height 11. The press-button switch enables a continuous lowering of the pile table when the machine is stopped or working. In the case where sheets are separated sequentially from the top of the pile 10 and fed to the machine, the pile table is raised intermittently by the above mechanism to maintain the pile height substantially at the height 11.

Abstract: 1,054,937. Bookbinding machines. LEIPZIGER BUCHBINDEREIMASCHINENWERKE VEB. Oct. 14, 1963, No. 40473/63. Heading B6A. In a machine for gluing and binding books of the kind wherein the books are conveyed from one station to another by clamps which move on guide rails, the clamps are opened and closed by control means which includes a device on the clamp jaws for holding them open, and an actuating device on the machine frame which causes the jaws to close. An endless conveyer chain carries a number of carriages 1 each having rollers 8, engaging fixed guides 5, 6, 7, and a fixed supporting jaw 2 provided with a boss 9 in which a guide rod 10 is fixed. A movable clamping jaw 3 having arms 12, 13 is slidably mounted on the rod 10 and guided on a rod 18 secured to the jaw 2, and is urged towards the jaw 2 by tension springs 17. An arm 15, Fig. 3 (not shown), integral with the arms 12, 13 and the jaw 3, co-operates with a roller 34 in the opening and closing positions of the jaws: in the closing position, the roller 34 is moved backwardly to allow an even movement of the jaw 3 into closing position, and in the opening position the roller 34 is moved forward to open the jaw 3 against the action of the springs 17. The roller 34 is carried by a rod 33 adjustably mounted on a frame 35 which is supported on links 30 ... 32 and is oscillatable by gearing 37, 38. The means for holding the jaw 3 in the open position comprises a one-way friction clamp, and includes a clamping lever 20, Figs. 5 and 6 (not shown), pivotally mounted on the rod 10. a @air of spaced pins on the lever embracing a rod 25 which is flexibly mounted an extension of the jaw 3, a spring 24 engaging between the extension of the jaw and one end of the lever 20, and a control roller 29 mounted in the path of the other end of the lever 20. With the jaw 3 open, the spring 24 tilts the lever 20 and the friction between the rod 25 and the pins on the lever is sufficient to hold the jaw in the open position. However, when the lever 20 engages the roller 29, the lever is tilted so that the pins do not restrain the rod 25, and the jaw 3 closes under the action of the springs 17. The conveyer chain is driven continuously, and books are inserted between the open jaws from below and are carried along by the rod 18 to a shaking station, a clamping station, and other stations where cutting, milling, gluing, back-lining, cover-applying &c. operations are performed.

Abstract: 1,226,901. Measuring physical properties electrically. SEMPERIT OSTERREICHISCHAMERIKANISCHE GUMMIWERK A.G. April 2, 1969 [April 5, 1968], No.17146/69. Heading G1N. A device for measuring the visco-elastic properties of elastomers, comprises a movable electromagnetic coil, 1, supporting along its longitudinal axis a rigid rod 2 carrying discs, 3, locating rubber test specimens, 4, 50 that in use longitudinally-directed vibrations are impressed on the specimens by axial oscillations of the coil which is driven by an audio-generator 5 through a power amplifier, 6. The amplitude of the oscillations is measured by a differential transformer, 10, and the current through the coil which is proportional to the axial distorting force is measured and maintained constant while the frequency of the generator is calibrated using a timer 9. To each specimen is applied a pre-load by means of discs 16, threaded spindles 17 and hand wheels 18, which load is measured using a Piezo-electric load cell 13, amplifier 14 and digital voltmeter 15, while the static distortion is indicated by clock gauges, 19. The pre-load and distortion are greater than the alternating load and distortion so that the test specimens remain between the discs. An oscilloscope 20 utilizes a signal from a velocity pick-up 21 to enable the device to be set at its resonant frequency. Formulae are given in the Specification relating the dynamic modulus of elasticity E<SP>1</SP> and the dynamic loss modulus E<SP>11</SP> to the measured quantities. (For Figure see next page)
