Title: Improvements in the severing and scoring or sheet material
IPC: B21D26/14
Filed: 1964-08-13
Abstract: 1,074,775. Shearing. CONTINENTAL CAN CO. Inc. Aug. 13, 1964 [Aug. 14, 1963], No. 32951/64. Heading B3W. A method of dividing a moving conductive section into individual elements comprises the steps of moving the section between a coil and a co-operating work member, and passing a large current pulse through the coil to induce an opposite and repelling force into the conductive section which is moved towards the co-operating work member so that a shearing force is developed in the conductive section. Fig. 2 shows the basic apparatus comprising a work guide 17, a coil 23 and an anvil 20 having a shearing edge 22. When a current pulse is passed through the coil the magnetic field surrounding the coil induces a current in the flat strip 15 which results in a repelling magnetic field so that the strip is forced against the shearing edge 22. The dimensions of the step 21 determine whether the strip is completely sheared or merely scored. Fig. 3 (not shown), illustrates the apparatus adapted to operate on a tubular section (25). The coil (29) and the anvil (30) may be interchanged in position. The anvil (30) may be replaced by a second coil (55), Fig. 9 (not shown), through which a current pulse is passed to produce a field opposed to the field produced by the internal coils (37). The coil support shaft (34) has guide members (35) thereon and may also conduct coolant to the working area. Fig. 10 (not shown), illustrates the use of an anvil having a shearing edge (59) and also secondary coils (60), the purpose of which is to limit the outward movement of the tube in order to reduce the friction on the edge (59). Flying shear.-Fig. 11 (not shown), illustrates an apparatus in which the anvil is external and consists of halves (60, 65) mounted on endless chains (69 and 71) driven so that the halves travel at a speed equal to, or slightly greater than, the speed of the section (25), and in the working position co-operate to form a complete anvil. In a modification, Fig. 13 (not shown), the anvil (74) is supported by a resilient diaphragm (77). A copper ring (80) is repelled by the field produced when a current pulse is passed through a coil (82) which is energized simultaneously with the coils (63). In a further modification, Fig. 14 (not shown), the anvil is reciprocated longitudinally of the section (25) by a cam. The apparatus may also be used for cutting laminates of metal and paper or plastics.

Title: Adder
IPC: G06F7/501
Filed: 1961-09-18
Abstract: 911,728. Tunnel diode switching circuits. RADIO CORPORATION OF AMERICA. Sept. 18, 1961 [Oct. 10, 1960], No. 33411/61. Class 40 (6). [Also in Group XIX] An adder comprises a Wheatstone bridge circuit having a negative resistance diode in one arm and resistive elements in the other arms. Two equal resistances 16, 14 and a third resistive element 18 are placed in three arms of a Wheatstone bridge circuit, a tunnel diode 12 being placed in the fourth arm. When only one of the three inputs 31, 33, 35 is supplied with a pulse, indicative of a binary " one," the diode assumes the low voltage, high current operating state 1 of its characteristic (Fig. 2), in which its resistance is equal to that of the resistive element 18, so that there is no voltage drop between the " carry " output terminals 28, 24, but the current flow i 1  through resistor 14 causes a voltage drop between the " sum " output terminals 24, 26, representing a binary " 1 ". When two of the three inputs receive pulses, the tunnel diode switches to the low current region of its high voltage state (operating position 40) where its high resistance produces a voltage difference between the " carry " terminals but the small current i 2  through the diode causes substantially no voltage difference at the " sum " terminal. When all three of the inputs receive pulses the diode enters the high current region of its high voltage state, where its static resistance is much greater than the resistance of the element 18 so that the major portion of the current flows through the branch 18, 16 of the bridge circuit. This causes a " carry " output of " one " between the terminals 28, 24. The current i 1  flowing through the resistor 14 also causes a substantial voltage drop at the " sum " terminal 24, also indicative of a binary " one." The values to be expected from the output terminals when specific values are given to the resistors are given in the Specification.

Abstract: 428,672. R÷ntgen ray apparatus. MULLER AKT.-GES., C. H. F., 24, Rontgenstrasse, Hamburg, Germany. Nov. 26, 1934, No. 33957. Convention date, Nov. 27, 1933. [Class 39 (i)] In an arrangement comprising a tube having a rotary anode, the device for adjusting the load of the tube at will has connected with it a device for controlling the speed of the anode so that the speed is higher at high loads than at low loads. The variation in speed may be accomplished by changing the stator voltage or frequency or by changing the stator pole system. In one form, a tube 1 is supplied from a hightension transformer 4 and has an anode 2 caused to rotate by a three-phase stator 33. In the position shown, which is suitable for radioscopy, the windings 33 are supplied through an impedance 37 and resistances 29 and 30 are connected in series with the filament heating transformer 31. In this position the anode 2 just revolves. Closure of the switch 14 actuates the switch 9 which substitutes resistance 28 for resistances 29 and 30 in the filament heating supply and short-circuits impedance 37 in the supply to the transformer or frequency-changer feeding the stator windings 33. The transformer 4 is now supplied through a timeswitch 22 from a regulator 23 giving a highvoltage suitable for exposure work. In a modification, the tube is suplied from a Greinacher circuit. On changing from radioscopy to exposure work a switch is actuated which energizes a solenoid arranged so as to break a switch in the supply to the tube and simultaneously cuts out the filament heating transformer. The switch then closes contacts short-circuiting an impedance in the stator supply and other contacts again supplying the filament. When it is desired to make an exposure the heating currents of the valves in the Greinacher circuit are interrupted and the condensers discharge through the tube. A time-delay switch subsequently to or during the discharge cuts off the filament heating current. Specification 385,757, [Group XXXVII], is referred to.

In a colour television transmitter for transmitting a SECAM type (Trade Mark) composite video signal in which two pre-emphasized colour signals A 1  and A 2 , e.g. (R-Y)/K 1  and (B-Y)/K 2  respectively, are linearly frequency modulated on a subcarrier alternately at line frequency and passed through a coding filter whose gain increases on either side of a frequency Fc of the variation range of the instantaneous frequency of said frequency-modulated subcarrier, the signals A 1  and A 2  have different resting frequencies, Fo and F<SP>1</SP>o respectively, positioned asymmetrically on either side of frequency Fc, and frequency Fc is positioned towards the instantaneous frequency of the subcarrier corresponding to the transmission of signal A 1  for the maximum algebraical value of the difference-signal R-Y. This positioning of frequency Fc which is towards the lower frequencies since K 1  is negative reduces the noise present in the highly saturated red portions of the picture. Fig. 1 shows the centre part of the gain vs. frequency wave of the coding filter. The minimum of the gain characteristic is located between F<SP>1</SP>o and Fo but due to the positioning referred to above it is 40 kc/s. from F<SP>1</SP>o and 116 kc/s. from Fo. The Specification describes in detail embodiments of transmitters, Figs. 2 and 3, not shown, in which the outputs of two harmonic generators having resonant frequencies Fo and F<SP>1</SP>o are compared in a phase comparator with the output of a frequency modulated oscillator to develop control signals which are applied to the frequency modulated oscillator to modify its resting frequency in alternate lines when signals A 1  and A 2  are applied thereto. The Specification also describes a receiver, Fig. 4, not shown, which includes a decoding filter whose gain vs. frequency curve compensates for that of the coding filter in the transmitter.
