Title: Automatic restart system
IPC: D04B35/10
Filed: 1973-06-01
Abstract: 1433145 Controlling A.C. motors A A KRYSZEK 1 June 1973 [8 June 1972] 26375/73 Heading H2J [Also in Division D1] A system for controlling an apparatus comprises a stop motion device for stopping operation of the apparatus and for actuating a timing device which remains actuated for a predetermined time and means for preventing reinitiation of operation of the apparatus if the stop motion device remains actuated at the end of the predetermined time. A knitting machine comprises devices 16, 18 for closing one or both of a pair of contacts 27, 47 should the tension in the yarn 10 being knitted have an abnormal value. For automatic restart type of operation of the machine a switch S1 is closed and the machine is started by momentary depression of a push-button switch 48. Relay B is thus energized which causes energization of control relay C and contactor A so that a motor 24 is energized to run the machine. Whilst the motor is running a relay E is energized which opens contact E1 to inhibit operation of a timing device T. Should an improper tension develop in the yarn 10 one or both of the switches 27, 47 close and relays F, D are energized. Contacts D1, D2, F1 open so de-energizing contactor A to stop the motor 24. Relay E de-energizes to close contact E1 whereupon the timing device T is actuated, relay C remaining actuated by relay B is disabled by the open contact D1. After a predetermined time (say 4 seconds) the timing device T closes contact T1 and opens contact T2. If after this time an improper tension still exists the relays F, D will still be energized so preventing re-energization of contactor A and the relay C will become deenergized to shut down the machine. Should the normal tension be restored during the time the relays F, D will be de-energized so that on closure of contact T1 the contactor A will reenergize to restart the motor 24 and the relay C will remain energized by the closure of contact D2.

Title: An improved book-binders' press
IPC: B42C13/00
Filed: 1928-09-14
Abstract: 322,552. Murray, J. Sept. 14, 1928. Bookbinding-presses.-In a bookbinding-press provided with a fixed head and a platen movable by hand to impart a preliminary pressure to sheets located between the platen and head, a train of gearing and an electric driving-motor are introduced automatically at the end of the first stage movement in order to impart the final pressure. The invention relates more particularly to improvements in the bookbinding-press described in Specification 181,207. A face plate 7, Fig. 2, resiliently mounted on the fixed head 1 is provided on its underside, Fig. 3, with an insulated conductor 17 which bridges a pair of contacts 18, 19 on the underside of the fixed head when the initial hand pressure is transmitted by the platen 2. A tappet rod 8, Fig. 1 (not shown), connected to the face plate 7 is simultaneously moved longitudinally to bring a sun-and-planet gear into operative connection with a pinion 4 secured to the rear of the platen 2, the sun-and-planet gearing contained within a casing 9 being connected by a driving-belt 15 to the motor 14. The bridging of the contacts 18, 19 by the member 17 closes the motor circuit and the power pressure is then applied. The contact 18 is connected to a bus-bar 20 adjacent to a parallel bus-bar 22 which is normally connected to it by a brush 38 on. an insulated arm 37 mounted on the platen 2. The platen also carries a face-plate 25, and between the platen and face-plate is interposed a plate 26 which is spaced from the platen by springs 27, and from the face-plate by springs 28, direct connection between platen and face-plate being provided by springs 28<1> passing through apertures in the plate 26. A set-screw 29 through the lower end of the face-plate engages one arm 30 of a bellcrank lever pivoted at 31 to the platen 2 and provided with an arm 32 which is urged downwardly by a spring 33 and provides a latching engagement with an arm 34 on a shaft 35 carry. ing the brush arm 37. The arrangement is such that, when the mechanical pressure is applied by the rack-bar, the face-plate 25 is pressed towards the platen and, at a point determined by the adjustment of the screw 29, the bell-crank lever 30, 32 is tripped by the screw, allowing the brush 38 to move away from the bus-bars 20, 22, thereby breaking the circuit and stopping the motor. The books are then tied up, and a lever 10 is operated to disengage the pinion 5 from the sun- and-planet gear to allow the platen to be pulled back by hand. The contact 17 automatically springs away from the contacts 18, 19 and, during the rearward movement of the platen, a cam 41 on the underside of the table 3 engages a roller 40 on an arm 39 secured to the shaft 35, which is thereby rocked to bring the brush 38 again into contact with the bus-bars 20, 22.

Abstract: 478,385. Step-by-step conveyers. BARNETT & FOSTER, Ltd., and RAYMOND, C. W. Oct. 6, 1936, No. 27141. [Class 78 (i)] A machine for agitating the contents of bottles to effect a mixing thereof, comprises an undulating track along which the filled and closed bottles are caused to travel endwise and be repeatedly tipped over during their travel. In the embodiment shown, the bottles are fed singly by a conveyer 17 and fingers 19 on to a track comprising a series of " hills " and "valleys" bounded by walls 3, 4. A bottle 26, Fig. 4, conveyed to the first " valley " falls on to a lift member 5 fixed to a rod 6 connected by a connecting rod 9 to a crank 8. The member 5 which is moving downwards, engages the arm 11 of the wall 3 by means of a cam 14 and tilts it about its pivot 10 to push the bottle against the wall 4, Fig. 5. The member 5 subsequently rises to the top of the valley and the bottle then falls by its own weight into the next valley where it is, received neck downwards on another lift member 5. The bottle is subsequently pushed against the wall 4 as before, and then raised by a member 5 so as to fall into the next valley, this cycle of operations being repeated until the bottle reaches the last valley into which it is deposited neck uppermost. The wall 4 of this valley is vertical so that the bottle may be lifted and then transferred by a finger .22 to a conveyer 18 in an upright condition. The cranks 8 are secured to shafts 15 which are geared together by sprockets and chains 16. The parts of the track with which the bottles make contact are faced with rubber or the like.

Title: Improvements in or relating to circuit arrangements for generating electrical pulses
Inventor: BLUNDELL GORDON ROY
IPC: H03K5/08
Filed: 1965-04-13
Abstract: 1,084,583. Pulse circuits. MULLARD Ltd. Feb. 14, 1966 [April 13, 1965], No. 27207/66. Divided out of 1,084,582. Headings H3P and H3T. In a circuit for generating a waveform having discrete voltage levels, a first incident pulse is fed to a shunt clipping circuit so that the onset of the required waveform is derived from the clipped leading edge, a second incident pulse being fed to a specified series clipping circuit so that the termination of the required waveform is derived from the clipped-off leading edge of the second incident pulse. The Specification describes apparatus, such as a linear accelerator, having a beam of charged particles, the pulse duration of the beam is controlled by deflection modulation with respect to an apertured shield 2. The deflection plate A is first biased so that when the beam is emitted by a source 1, it is deflected along path 5. The bias is then removed from plate A by means of a positive-going pulse allowing the beam to pass the aperture 3 on to a target after which plate B is pulsed, deflecting the beam along path 5 or 6 and so terminating the beam pulse received by the target. As described, the source 1 is an electron gun; plate A is normally biased via diode 13 to - 8 kv. whilst B is earthed by diode 21. Shortly after the onset of a pulse of electrons from 1, thyristors or thyratrons 10, 12 are turned on by a pulse from 17 giving a + 16 kv. pulse at the cathode of valve 10 which is clipped to earth by valve 12 so as to utilize the part of the pulse having the shortest rise time. This allows the electron beam to traverse path 4 on to the target. After one or more nano seconds, thyratron 27 is turned on giving a negative-going pulse at the anode, the lower 8 kv. passing diode 25 and turning off diode 21 so as to provide at B a pulse which deflects the beam to path 6 so terminating the pulse on the target. The use of the lower part of a clipped pulse at plate A and the upper part of a delayed clipped pulse at B makes the rise and fall times of the pulse on the target extremely short, the duration being dependent on the delay between pulse generators 17, 18 which is controllable by a low level circuit. The H.T. line 19 is pulsed at +18 kv., a delayed pulsed supply being fed to the screens if tetrode thyratrons are used at 10, 12, 27. Diode 21 may be replaced by a thyratron triggered from 17. A single deflection plate may be employed if a circuit comprising valves 25, 27 is connected to plate A. The beam 4 and target (not shown) may form a high-power switch.
