Abstract: 1,034,818. Automatic control of shears. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 30, 1963 [Sept. 11,1962], No. 34696/62. Heading G3R. In a control system for a flying shear, a device 51 sums the voltage from strip-driven tachometer generator 17 with a negative voltage from tachometer generator 15 which is coupled with the motor 13 driving the shears. A device 53 integrates the output from summing device 51. A further summing device 55 receives an input from terminal 39 representing the predetermined lengths of material which is to be cut off, and an input from terminal 41 indicating the periphery of the circle swept by the shear blades, as well as an input from the integrating device 53. The output supplied to the motor regulator 21 represents the sum of the shear circle periphery and.the time integral of the linear velocity of the material, less the sum of the desired length and the time integral of the peripheral velocity of the shear blades, the integrals being taken from the datum point given by the making of the last cut. The integrator 53 is set to zero by a pulse applied through line 47 from the tachometer generator 15. A holding signal is applied through terminal 49 to hold the integrator at zero until a desired starting point relative to the strip is reached.

Title: Improvements in or relating to weighing machines
IPC: G01G13/00
Filed: 1937-12-17
Abstract: 507,607. Delivering material from hoppers. SIMON, W. G., and SIMON, F. R. Dec. 17, 1937, No. 35056. [Class 78 (i)] [Also in Group XVIII] In an apparatus suitable for supplying, powdered &c. material to a mixing vessel, an automatic weighing machine intermittently discharges the weighed quantities into a hopper, and the outlet from the hopper is controlled to effect a continuous delivery of the material. The material discharged from the weigh pan 13 falls into a delivery hopper 19 provided at the base with a delivery tray 20 continuously vibrated by an electromagent 21 to deliver the material continuously to a mixing or other vessel. As the quantity of material in the delivery hopper 19 becomes exhausted a switch 22 is operated by the rise of a counterweighted flap, 24 liberated by the sinking material. The switch 22 introduces a resistance 23 into the circuit of the magnet 21 thus reducing the vibration of the delivery tray 20 and retarding the delivery sufficiently to prevent emptying of the delivery hopper before a further weighed charge is introduced. The added material depresses the flap 24 and restores the full vibration of the tray 20. The resistances 17, 23 are variable to regulate-the vibrations of the trays.

Title: Apparatus for testing the insulation between turns and between layers of a transformer winding
IPC: H02H7/04
Filed: 1945-11-30
Abstract: 627,999. Fault testing. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 29, 1946, No. 35491. Convention date, Nov. 30, 1945. [Class 37] In apparatus for testing the inter-turn insulation of the winding of a distribution transformer 1 (Fig. 1), having a large distributed series winding capacitance, a known impulse generator 5 is connected to terminal 2 and terminal 3 is connected to earth through capacitor 7, shunted by resistor 9, the combined timeconstant being 50- 100 micro-seconds. A predetermined voltage wave-form (Fig. 4) produces a current wave in the winding and a consequent voltage drop across capacitor 9, and produces a trace (Fig. 8) on oscillograph 8, connected across the capacitor, discharged between tests by the resistor 9 which also limits the voltage rise across the capacitor. Insulation defects are detected by comparing the trace with that of a known good transformer. Fig. 8 shows the trace produced before failure and Fig. 9 that when there is a short-circuit of one turn in the winding. Were a resistance used instead of a capacitor, the large initial voltage surge would make trace interpretation difficult.

Abstract: 1524035 Feeding sheets PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 2 Sept 1975 [5 Sept 1974] 36097/75 Heading B8R Insertion of a record carrier, e.g. an account card, into an accounting machine moves a card-sensing lever to a position in which a photoelectric switch is operated, the lever being maintained in such switch-operating orientation when it is subsequently withdrawn from the card guide slot. Insertion of a card 22 pivots a lever 7 to the position shown in Fig. 2, in which a shield 28 of lever 7 has moved to actuate a photoelectric switching device 10. Lever 7 is pivotally mounted on a plate 2, itself pivotally mounted at 5. Actuation of the switching device 10 causes a shaft 12 to rotate through 180 degrees (from the Fig. 2 to the Fig. 3 position), cams carried by shaft 12 performing two functions during such rotation. Firstly, a lever (15, Fig. 4) is pivoted to move a pressure roller 14 against a drive roller 17 for transporting the card to a processing position (not shown). Secondly, cam 1 permits spring 22 to pivot lever 18, a lug (38) of which coacts with lug (37) of plate 2 to pivot the latter, together with lever 7. Initial movement brings toothed sector 23 of lever 7 into engagement with a rubber abutment (9) carried by pivoted spring-loaded lever 24. Upon further movement, such engagement maintains lever 7 orientated so as to maintain the actuated state of switch 10. After processing of the card is completed, the shaft 12 is rotated through a second 180 degrees to withdraw roller 14 from roller 17 and to push lever 18 back to its starting position. Plate 2, which is connected by spring 21 to lever 18, is thus also returned, lever 7 remaining in its switch-actuating position until the engagement between sector 23 and abutment 9 is broken.
