Abstract: 1335477 Slitting webs CREBAN MFG CO Ltd 29 Sept 1972 [1 Oct 1971] 45710/71 Heading B4B An adjustment means for the displacement of the cutting edge of a rotary disc cutting blade in the axial direction of the blade according to the deviation of an intended line of cut longitudinally in a web of material, the adjustment means comprising a shoe 13a engageable with a channel-like formation 15a in the web and a mechanical coupling means 13d adapted to automatically effect a shift of the cutting edge of the blade corresponding to the displacement of the shoe in the channel 15a. The shoe 13a is connected to a link 13c which is mounted on one end of a flexible arm 13b, the other end of the arm being connected to a fixed part 14 of the cutting machine; the arm is adjustable in length by means of a collar (not shown). A claw member 13d is mounted on the shoe so that any movement thereof causes the blade to be moved correspondingly along a splined driving shaft 12. The edge of the shoe in contact with the material may be coated with P.T.F.E., the edge being maintained in such contact by a spring or magnetic means. In the event of the shoe riding out of the channel-like formation, i.e. over selvedges 15b, Fig. 3, the lifting movement of the shoe actuates a micro-switch via, e.g. a linkage, to stop the slitting machine. As shown a pair of identical cutting discs are mounted on a common splined shaft; alternatively, the discs could be rotated by individual motors mounted for pivotal movement such pivoting movement being controlled by claws in engagement with the blade. In a further modification, instead of the shoe being carried by the flexible arm 13b it may be suspended from a transverse element via pivoted joints to permit movement of the shoe.

Title: Circuit for checking the correct operation of a control circuit
IPC: D05C15/00
Filed: 1971-09-29
Abstract: 1338805 Checking system SHORELL Ltd 5 July 1972 [29 Sept 1971] 45268/71 Heading G4H [Also in Division H3] In an electrical control and checking system in which neither less nor more than a predetermined number of control devices must operate together, a signal representative of the number of devices actually actuated is generated and compared with a reference signal; an alarm condition being initiated if a predetermined relation between the signals is not achieved. As described, the control devices are solenoids; only one should operate at a time and the system includes a parity check to ensure that the solenoid which operates is one of a subgroup. The solenoids are incorporated in a carpet tufting machine. The pattern is coded in binary form on a tape sensed by photo diodes A, B, C and decoded at 2 to drive relays H, the contacts HA of which operate solenoids HB. Resistors HC are also switched by contacts HA. The alarm lamp L is switched on by SCR on conduction of transistor T5 which is maintained in a normally conducting mode by Zener ZA. A potential is applied to FI only when the solenoids are being operated; at all other times a positive potential at lead K prevents operation of the alarm. Parity signals on line P for solenoids 2, 3, 5 and 8 and from the anode of diodes DG for the other solenoids earth the bases of transistors T4, T3 respectively which form an exclusive OR gate. In operation, when one relay operates, one resistor HC passes current and the potential at the junctions of HC and RA and of RC and RD are equal- T6 does not conduct. The voltage across RB is rectified by diodes DA, DB and charges capacitor CB. If the correct parity signal is applied, one of T3 and T4 conducts, the cathode of ZA is pulled down to earth and the SCR does not fire. If the parity check is incorrect, i.e. a relay in the wrong group has operated, the exclusive OR gate will not conduct and the alarm will light. If no solenoids operate, CB does not charge and the OR gate does not conduct. If too many solenoids operate, the voltage across RB charges CB, but, due to an excessive voltage across RA, T6 conducts, CA charges, T2 conducts and shorts out CB, disenabling the OR gate.
