Title: Method and apparatus for slitting and or scoring paperboard
IPC: B26D7/26
Filed: 1970-09-21
Abstract: 1315407 Cutting and scoring apparatus HARRIS-INTERTYPE CORP 21 Sept 1970 [4 Dec 1969] 44859/70 Heading B4B A machine for cutting and/or scoring paperboard comprises a plurality of rotatable blades 92 mounted on a shaft 72 for co-operation with a roller 94, individual drive means 90 for moving the blades along the shaft and programmed control means for storing information regarding desired blade positions for successive production runs of the machine and for controlling operation of the drive means to adjust the positions of the blades on the shaft between successive production runs. The blades 92 are in the form of cutting discs each rotatably mounted on housings 86 which are movable along a track 82 secured to a beam 80. The track is provided  with a rack 84 for engagement by pinions 88, one being provided on each drive shaft of the  individual stepping motors 90. The blades are rotated simultaneously by a shaft 72. The roller 94 is covered with a bristle backing and is arranged to be moved out of contact with the blades during a setting-up operation by an actuating means 44; these means are described in connection with a scoring blade assembly 20, Fig. 1, which is otherwise substantially identical with the slitting assembly just described except that the anvil roller 42 is covered with a plastics material. The actuating means 44 includes a piston-and-cylinder device 46, 48 connected to a segment 50 forming part of a conventional eccentric adjusting means 53, Fig. 2; an indicator scale 54 and limit stop 52 are provided. In order to ensure that the adjustment of the roller is the same at each end thereof, a gear segment 56, Fig. 2, is attached to each end of the shaft for the roller, each segment meshing with pinions on a second shaft 58. The stepping motors are controlled by a computer via electronic circuitry an example of which is described (Figs. 6 to 9, not shown). The information fed into the computer can be derived from punched cards or tape.

Abstract: 1,164,357. Petrol pumps. KIENZLE APPARATE G.m.b.H. 5 Oct., 1967 [25 Oct., 1966], No. 45396/67. Heading G4D. A receipt printer for a self-service petrol pump prints only when the nozzle is hooked into home position. When the nozzle is returned to its housing after a dispensing operation, movement of a permanent magnet (131) opens a reed switch (132) to stop the dispensing motor. Star-wheels (24, 25) coupled to the price and volume registers are engaged by wedges to align print wheels to the nearest whole number at the same time as the drive to the registers is disengaged (22, 23). If a receipt is required the customer rotates a crank (11) provided with a full-stroke device and printing and delivery of the receipt follow. Dispensing is prevented during the printing operation and vice versa. When the nozzle is removed from its housing for a subsequent dispensing operation the star-wheels (24, 25) are released and the registers are restored by heart cams in known manner. The drive to the registers is then restored and the pump motor energized.

Title: Measurement to ultrafiltration rate

Filed: 1975-11-04
Abstract: 1534701 Dialysis COBE LABORATORIES INC 4 Nov 1975 [4 Nov 1974 (2)] 45715/75 Heading B1X A dialysis machine having apparatus for measuring the ultrafiltration rate includes a dialyzer, inlet and outlet conduits for dialysate, a flow meter having an inlet in fluid communication with the outlet conduit, valve means in the inlet conduit for interrupting flow of dialysate to the dialyzer, valve means in the outlet conduit for diverting flow of dialysate from the outlet conduit to the flow meter, flow-producing means for producing a negative pressure in the dialyzer and means for maintaining the negative pressure in the dialyzer, during interruption and diversion of the flow, at a value substantially equal to the average value of the dynamic pressure therein prior to the interruption and diversion. As shown, operation of valve 14 from the "rim" to the "bypass" position shuts off the supply of dialysis fluid to the dialyser 18 and shunts it back to the supply, while maintaining the pressure in dialysate space 34 of the dialyser; under these conditions any change in this pressure, measured by meter 12, is due to ultra filtration.

Title: Transistor oscillation generators and inverters
IPC: H02M7/5383
Filed: 1962-12-04
Abstract: 1,032,125. Transistor inverter oscillating circuits. WESTERN ELECTRIC CO. Inc. Dec. 4, 1962 [Dec. 29, 1961], No. 45726/62. Heading H3T. [Also in Division H2] In a transistor oscillator circuit base drive current for the transistor is fed back from a secondary winding of a transformer, part at least of the primary of which is connected in a closed loop path with the emitter collector path of the transistor and a D.C. source, over a closed loop series feed-back circuit including a frequency control means comprising a series resistor and capacitor. With reference to Fig. 1 when the D.C. supply 100 is connected into the circuit transistor 102 is biased into conduction by a starting current flowing through resistor 103 and a voltage is induced in feedback winding 109 such as to bias transistor 102 further into conduction. Capacitor 107 charges exponentially to the polarity shown through the loop comprising winding 109, resistor 106, baseemitter path of transistor 102 and diode 105 resulting in transistor 102 becoming biased off. The collapsing flux in the saturable transformer induces a potential in winding 109 such as to bias transistor 102 further into cut-off and at the same time bias transistor 101 into a conducting state. Current induced in winding 109 now flows in the loop including the base-emitter path of transistor 101 and diode 104 so that capacitor 107 discharges and then charges to a potential of opposite polarity to that shown in Fig. 1. When the base drive potential of transistor 101 is insufficient to maintain this transistor conducting the flux in transformer 108 collapses and transistor 102 is biased into conduction again and the cycle repeated. The frequency of oscillation is determined by resistor 106 and the voltage drop across the base-emitter of the non-conducting transistor in each halfcycle is limited to the forward voltage drop across the appropriate diode so that the transistor is not driven far into cut-off. The saturable transformer 108 is operated in its linear portion of its BH characteristic. The D.C. to D.C. converter of Fig. 2 has two R.C. networks 201, 202 and 203, 204 employed for frequency control and operates in a similar manner to the circuit of Fig. 1, the transistors 101, 102 being alternatively conducting and non-conducting and the circuit includes two starting resistors 103, 207. Capacitor 107 of Fig. 1 may be replaced by a non-linear capacitor, Fig. 3 (not shown), having a rectangular hysteresis loop which saturates before transformer 108. The feedback winding 109 is connected to the circuit via a double pole switch the position of which determines whether the output is a sine wave or pulse.

As shown, a hollow grinding wheel spindle 21 is rotated by a pulley 80 while the shaft 60 for the balancing mass 39 is driven when required by a motor 83 through strain wave gearing 86, the motor being supplied with current through brushes 99, 100 and 101 in contact with rings 102, 103 and 104 on a motor housing 81 rotatable with the grinding wheel spindle. A sufficiently large torque is applied by the motor to the shaft 60 to overcome the friction of a brake disc 66 which is continuously urged against a face plate 64 of a carrier unit consisting of carriers 45, 46 secured together by screw 51. A shaft 37 is carried by the carrier unit and is driven by a pinion 36 meshing with internal teeth 35 of a casing 27 mounted by screws 28 to the grinding wheel spindle 21. Rotation of the shaft 60 turns the carrier assembly within the hub of the grinding wheel causing the pinion 36 to roll around internal teeth 35, the number of teeth being an integral multiple of those of the pinion plus or minus 1 to 3 so that the path 125 along which the centre of gravity of the balancing mass 39 is moved is hypotrochoidal (or hypocyloidal if the point is on the circumference of the pinion).
