Abstract: 558,593. Cutting-machines. BARNARD, C. W. July 8, 1942. No. 9495. Convention date. July 3, 1941. [Class 31 (i)] [Also in Groups XVI and XV] In a machine for making and packaging stamp hinges, and mounting strips for photographs, the stock 2 is fed from a take-off reel 3 and is folded longitudinally by a folder 6 with bent edges 7, 8 adapted to bend one edge upwardly and over. The stock is then directed by fingers 11, 12, Fig. 7, to feed rolls 13, 14 which may also crease the stock, and spaced guides 15, 16 direct it to a fixed cutter 18 and a reciprocating cutter 19 actuated by a slide 22 controlled by adjustable crank mechanism 23-29 from a shaft driven by a pulley 34 and belt 36. The pulley shaft drives a shaft 40 of one of the feed rolls 13, 14 by a chain 39, and shaft 40 drives a worm 51 engaging a worm wheel 52 which operates mechanism for tripping the feed roller 13 after a given number of finished hinges have been discharged into a chute 85 by means of air blasts from a nozzle 85. During the cutting operation, the continued advance of the stock causes bulge adjacent to the cutting edges 18, 19 and a spring stripper 17. Fig. 7, is raised during the cutting action and acts to straighten out the bulge after a hinge is cut off. In a modified form of cutter, Fig. 13, a number of rotary blades 89 driven by bevel gearing 91, 92 replaces the reciprocating blade 19. After a given number of hinges have been discharged into chute 84 the feed roller 13 is raised to stop the feed by energization of an electric magnet 70, which operates a cam 74, Fig. 1, to raise the 'bearings of roller 13 against the action of springs. The circuit to magnet 70 comprises contacts 61, 62 adapted to be closed by the operation of a pin 59 on a disc 56 which is driven frictionally from the worm wheel 52. The shoot 84 may co-operate with other adjustable shoots which can be used in turn to direct the given number of hinges to an envelope under the shoot. A pair of spring-pressed rollers may be used to break up the gummed surface which is led over a rubber &c. roller and is acted upon its back by a hard metal ribbed roller.

Title: Improvements in or relating to circuit arrangements for stabilizing voltages
IPC: H04N3/18
Filed: 1958-03-26
Abstract: 891,486. Automatic voltage control systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 26, 1958 [March 28, 1957], No. 9712/58. Class 38 (4). In a system for stabilizing the direct voltage across a load 7 supplied through a transformer 4 and a rectifier 5 from an amplifying valve 1, supplying an alternating current of sawtooth waveform to a deflection coil of a television receiver, an alternating voltage proportional to the direct voltage is derived through a capacitive voltage divider 8, 9 from a secondary winding of the transformer 4. The voltage across the capacitor 9 is applied to the grid of a triode valve 17, the output of which, through a capacitor 20, is rectified by a diode 21 to produce across the parallel combination of a resistor 22 and capacitor 24 a direct bias voltage for the control grid of the valve 1 tending to maintain constant the voltage across the secondary winding of transformer 4. The voltage in a tertiary winding 31, tightly coupled to the primary of the transformer 4, is shown to be dependent on the current through the load 7 and through a rectifier 32 is applied as a direct voltage bias to the grid of the triode 17 to compensate for the internal resistance of the high-voltage rectifier 5. A voltage dependent resistor 34 is employed in a potential divider 33, 34 connected to the rectifier 32 so that with an increase in voltage across the potentiometer, the bias to the grid of the triode 17 increases only very slowly. The capacitors 8, 9 may be formed by a cable having an inner conductor enclosed by a pair of insulated conductive coatings, or by a metal strip arranged in the proximity of the secondary winding of the transformer 4. The compensating bias to the triode 17 may be derived by replacing the rectifier 32 by a rectifier 37, a capacitor 36 and a resistor 38 connected as shown by the dotted lines.

Abstract: 1298271 Transistor amplifying circuits RCA CORPORATION 2 March 1970 [3 March 1969] 9875/70 Heading H3T The bias on a transistor amplifier having direct coupling to a signal source is rendered independent of a D.C. component in the signal from that source. The amplifier comprises transistor 10 Fig. 2, which is biased by means of resistor 32 and diode 12, which comprises a similar transistor with base and collector strapped together. The signal is applied to its base over resistor 22, from a source comprising an A.C. component 20 and D.C. component 18. The D.C. component 18 of the signal is also applied over resistor 30 which has the same value as resistor 22, to the base of a transistor 26, the collector of which is returned to the base of transistor 10: transistor 30 is biased by means of diode 28 which Comprises a similar transistor with base and collector strapped together. Since diode 28 and transistor 26 comprise similar transistors and their bases are strapped together, they pass similar collector currents so that, resistors 30, 22 being of equal value, transistor 26 provides a path for all the current flowing through resistor 22, no bias current flowing from the resistor to transistor 10. In a modification, the bias resistor 32 is omitted and the transistor 10 biased by making resistor 22 of lower value than resistor 30 (Fig. 1, not shown). In a modification, the resistors 22, 30, Fig. 3 are returned to either end of the secondary of a transformer 34, the D.C. source being connected to its centre tap and the A.C. source to the primary winding. Alternatively, two separate A.C. sources may be coupled by means of transformers between the D.C. source and resistors 22, 30 respectively. The Specification also describes the application of the invention to a video detector circuit of the type disclosed in Specification 1,298,272.
