Title: Machine for processing linear material
Inventor: PATERSON JOHN
IPC: B23D36/00
Filed: 1961-06-19
Abstract: 988,364. Automatic speed and registration control. SAMUEL M. LANGSTON CO. June 19,1961, No. 22010/61. Heading G3R. A machine for cutting continuously fed sheet material 10 into lengths comprises main drive motor 18 coupled to feed-rolls 12 through main shaft 16 which also forms the input to Reeves drive 22 whose output is coupled through shaft 24 and crank mechanism 26 to knife cylinders 20. A differential gear train 30 is associated with motor 32 for varying the speed of the knife cylinders and hence the sheet length. A tachometer generator 34 detects the sheet speed whilst tachometer generator 36 measures the average speed of the knife cylinders. Adjustment of sheet length through the Reeves drive is effected by motor 40 intercoupling the drive 22 and crank mechanism 26. The difference between the voltages of the tachometer generators 34,36, is applied to comparator 58, and, if the sheet-length is correct, there is no error voltage, length adjustment being effected by resistor 44. The output of comparator 58 is applied to motor 32 which drives differential 30 to correct the error. If the error signal exceeds a predetermined value, relay 62 or 64 is actuated, according to the sense of the signal, and motor 40 is energized to adjust the drive 22. The sheetspeed is also detected by a tachometer generator 66 driven through impulse wheel 68, and detection of knife speed is made by photo-cell 70 associated with a mark on one of the rollers. A photo-electric detector 72 is used if printed matter is to be located relative to the knife edge. Pulses from the detectors 66,70, are fed to a digital error computer 74 for adjusting resistor 52 in circuit with tachometer generator 34. If the system is adapted to maintain the cut in register with print marks, pulses from detectors 70 and 72 will be coincident when the sheet length and location of cut are correct. If an error in location occurs so that the pulse from detector 72 precedes that from detector 70, the pulses from detector 66 are doubled during the interval whereby the next sheet is made shorter and the pulses from detectors 70,72 are brought into coincidence. If the pulse from detector 70 precedes that from dectector 72,the pulses from detector 66 are blocked and the next sheet will be cut longer.

Abstract: 841,422. Paper-making machines. DOMINION ENGINEERING WORKS Ltd. July 17, 1956, No. 22082/56. Class 96. A narrow, high-speed, modified Fourdrinier paper-making machine has a short wire-cloth 5 the upper run C of which hangs freely as a catenary between the breast roll 6 and the couch roll 7, so that water drainage from the pulp is aided by centrifugal force, and suction boxes and table rolls are not needed. The breast roll 6 may be at the same height, or at a higher or a lower level than the couch roll 7. The roll 8 is tiltable &c. so that it can act as a guide roll to correct wander of the wire-cloth, and the roll 9 is adjustably positioned for control of the amount of slack in the catenary C. The web S may be couched vertically upward with the aid of a water shower 13, an air blast 14, and centrifugal force as the wire moves around the roll 7. Alternatively, the web may be couched at any angle, or vertically downward. The wet press may have small diameter rolls 18, 19, each backed by two larger rolls 20 and 21, and driven by a wormtype speed-increasing gear train. No press felt is used and the high speed of the small rolls 18, 19 ensures the web S leaves cleanly. The rolls 6, 7, 8, 9 are cantilever-supported to facilitate wire-changing. The flow box 11 may be trunnion-mounted and have an internal rotating paddle which whirls the pulp and delivers it under pressure. Specifications 815,363, 841,427 and 841,441 are referred to.

Filed: 1972-05-11
Abstract: 1367003 Electronic fuel injection systems for I C engines ATELIERS DE LA MOTOBECANE 11 May 1972 [12 May 1971] 22100/72 Heading G1N In an I.C. engine fuel control system, a condenser C is discharged through the electromagnetic winding 1 of a fuel injector in synchronism with the cycles of the engine to thereby lift the needle of the injector to admit fuel, the discharge being varied to thereby vary the period of lift of the needle. As shown in Fig. 3, the engine alternates coil L is connected to charge the capaciter C through a diode D1, discharge being effected by the triggering of a thyristor in parallel with the winding 1. A diode D2 and a variable resistor R are connected in parallel with the winding 1 to vary the discharge through the winding 1. The resistor may be variable in dependence upon intake suction, temperature or the accelerater position.  In Fig. 4, the discharge is varied by a thyristor Th controlled by a dephasing circuit Cd connected as shown. In an alternative, Fig. 5 (not shown), the dephasing circuit Cd is connected to shortcircuit to a greater or lesser extent the winding L of the alternater to thereby vary the charging voltage of the condenser C. This is achieved by connecting a thyristor in parallel with winding L, this thyristor being controlled by the dephasing circuit. The system is particularly appropriate for use in a two-stroke engine where fuel is injected directly into the cylinders.

Filed: 1948-08-25
Abstract: 653,990. Case stacking. WEBSTER, A. H. Aug. 25, 1948, No. 22393. [Classes 78 (i) and 78 (iii)] A case stacking mechanism comprises means (1) for lifting a case (2) to a pre-arranged level, supporting means (3) for receiving the elevated case and for supporting it in the elevated position while the lifting means descends to receive another case for elevation thereto and movable means for moving the stack of cases therefrom. Fig. 1. Cases 2 are received by vertically reciprocating platform 1. The platform 1 rises, conveying the case until the case slides past pivoted pawls 3 and rests thereon. The movement of the pawls works a switch which causes the lift to descend again to receive another case. The platform 1 then rises again and pushes up the first case so that two cases now rest on pawls 3, and so on till on pawls 3 rest a stack of cases 2 of such a height that the switch 12 is operated by the top of the stack to stop the movement of the platform and to bring into operation pusher 6 which pushes the stack of cases rightwards on to palet 11 resting on grill 9, which is held by piston-rod 10. As the pusher 6 withdraws it operates a switch to bring again into operation platform 1 which commences to raise another case 2 till a second stack of cases 2 is resting upon pawls 3, whereupon actuation of switch 12 again releases pusher 6 which pushes this second stack on to grill 9, and this second stack in turn pushes forward the first stack of cases so that the latter operates switches 13. These switches prevent further movement of pusher 6 and also actuate piston-rod 10 which descends till the pallet 11 touches the ground and thus supports the stacks of cases; pallet and cases are removed; an empty pallet placed on grill 9; and piston-rod 10 supporting the second pallet 11 is raised to its original position to set switches 13 ready for the next sequence. Preferably there are two sets of pawls and two side-by-side pushers 6 working simultaneously and the pallet 11 then supports and discharges four stacks of cases. Specification 645,920 is referred to.
