Title: Improvements in or relating to apparatus for moulding dough
IPC: A21C7/04
Filed: 1948-11-01
Abstract: 658,627. Rounding-up dough. ORMEAU BAKERY, Ltd., CUSDIN, A., McHENRY, R. T., and HAMILTON, J. Nov. 1, 1948, Nos. 28250/48, 31762/48 and 3108/49. [Class 87 (ii)] A dough balling machine of the kind in which the dough is moulded by the use of cups which are given an orbital motion, is characterized in that each cup has flexible or resilient discs forming a ceiling adapted to bear down yieldingly on the dough piece. The endless band 1, Fig. 1, moves in the direction of the arrow in a stepwise fashion beneath a framework 2 supporting rows of inverted cups. Dough pieces 10 are placed inside the cups of row A, the framework 2 is gyrated and is then raised to permit the pieces to move to row B and so on. In Fig. 3 the cup comprises a flanged metal ring 5 having a tapered rubber ring 6 fitted therein and two felt discs 7, 8, clamped together and positioned as shown by the ring 6. The ring 6 may however be inverted. A modified form of cup. Fig. 5, consists of a ring 11 having two side floats 11a, Fig. 6, (not shown), over which ring is stretched a short length of rubber tubing 12 forming a double equally-tensioned ceiling. In an alternative form a circular part is cut out of the tubing to give a single elastic diaphragm, or the disc may be moulded with a relatively stiff edge. As shown in Fig. 7, spring means is provided to bear down on the felt discs, the spring being attached to a spider 16 having legs positioned between the disc 7 and the ring 5 by means of the rubber ring 6. Adjustment of the height of the cup ceiling and the spring pressure is effected by the nut 17 which raises or lowers the screw. In Fig. 8 (not shown), the spring is conical in shape. The assemblies shown in Figs. 5, 7, 8, may be used for rows B, C and D. Alternatively, in row D the cups may be left open to form rings and the internal diameter of each cup may be reduced by the insertion of a backing ring of rubber and then a rubber ring 6. The variable tensions of the ceilings enables the pressure on the dough to be eased progressively from cup to cup as in the natural hand action. In the first Provisional Specification the height of the individual or successive cups may be varied by packing discs, and the cup ceilings may be provided with felt rings attached around their inner edges to the ceiling but free at their outer edges.

Abstract: 279,869. Duoskop-Ges., (Assignees of Kucharski, S.). Oct. 27, 1926, [Convention date]. Kinematograph apparatus. - An endless film coiled on a support is subjected to a jogging or shaking motion by radially disposed rollers which support it and are themselves shaken by depressions or elevations on a driven disc; film-controlled means for regulating the speed of unwinding &c. may be provided. As shown, the film c passes from the projector b to the outside of a coil carried by radially-arranged rollers e. The rollers are rotated by the engagement of their ends h with a disc i having elevations n, or depressions, causing the rollers to be shaken. The rollers may have, at their upper ends, helical grooves q which guide the film towards the centre, and, at their lower ends, oppositely cut grooves r to restrain the central movement. The grooves q may be provided on parts only of the rollers, or on one side thereof, and enlargements s may be provided. The rollers may be made eccentric, or may be so mounted in their bearings as to produce the desired movements. The disc i is driven from the projector by a belt k and pulleys m, l, the pulley m being provided with an axially adjustable lower part z to vary its effective diameter, and, consequently, the speed at which the disc i is rotated. The part z is moved vertically, when the tension of the film increases by the action of the film on a roller u carried by a lever v connected by a cord w to a lever t ; springs x, y restore the parts to their original positions when the tension becomes again reduced.

Title: Improvements in and relating to rotational scanning systems
IPC: H03K4/12
Filed: 1951-12-07
Abstract: 701,620. Radar; pulse generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 7, 1951 [Dec. 8, 1950], No. 28743/51. Classes 40 (6) and 40 (7). [Also in Group XXXVI] D.C. voltages proportional to Œ sin e and Œ cos e are produced by generating from a sinusoidal waveform a pulse train of equal recurrence frequency, the phase displacement of the pulse train relative to the sine wave being proportional to e, and separately combining the pulse train with four phase-quadrature components of the sine wave to give four composite waveforms having envelopes whose amplitudes are proportional to Œ sin e and Œ cos e. The invention is applicable to a radar resolved P.P.I. or sector display in which the X and Y components of the timebase are modulated by the sine e and cos e voltages the angle e being the instantaneous angular position of the aerial. As shown the sine wave is generated by an R.C. oscillator VI, phase quadrature components thereof being produced at terminals A. B, C, D, and the component at B being applied to render V5 conductive during the positive half cycles thereby producing a train of sawtooth waves at the anode due to the effect of components R and C. The potentiometer P is ganged to the aerial and the positive voltage v at the slider which is proportional to e is applied to the cathode of V5 and so combined with the sawtooth voltage in the anode circuit. The resultant waveform, Fig. 5, is applied to the grid of a blocking oscillator V6 which fires each time the amplitude of the resultant waveform reaches a predetermined level L to give a train of pulses, Fig. 6 (not shown), the displacement of each pulse from a reference portion of the sine wave being proportional to the instantaneous amplitude of v. The pulse train is combined with a sine wave from B and the composite waveform, Fig. 7, is applied to a peak rectifier V10 whose cathode output comprises a D.C. voltage proportional to the envelope 14 of the composite wave which is proportional to sin e and this voltage is applied to one of the timebase circuits 5 to modulate the sweep voltage applied to one of the deflector plates of the cathode-ray tube V11. Voltages proportional to sin e and Œ cos e for modulating the sweep voltages applied to the other deflector plates are produced in a similar manner by combining the pulse train from V6 with sine waves from A, C and D in the peak rectifier V7, V8 and V9.

In an amplifier comprising an odd number of stages, in which an impedance Zt comon to the cathode circuits of the first and last stages provides negative feed-back, the effect of the anode current of the penultimate stage 2, part of which passes through the impedance Zt via the grid-cathode impedance Z4 of the valve 3, is neutralized by connecting an impedance Zc between the grids of the first and last stages. The impedances Z4, Zt, Zc, together with the impedance Zi of the source driving the amplifier form a Wheatstone bridge which is balanced with respect to the voltage appearing between the anode of valve 2 and earth. The arrangement may also be applied to a push-pull amplifier.

Abstract: 999,571. Transistor pulse circuits. STANDARD TELEPHONES & CABLES Ltd. July 23, 1963, No. 29132/63. Heading H3T. An amplifier comprises a first transistor VT1 having its collector coupled to the base of a further transistor VT2 of the opposite conductivity type, the further transistor having a collector load comprising an output transformer TR and a series resistor Rl which resistor is also in the base input circuit of the first transistor. The application of a pulse to the base of VT1 renders both transistors conducting (but not saturated) producing an output pulse across the load R3. Resistor Rl makes the input impedance of VT1 high, Zener diode Z limits the amplitude of the pulse and diode D ensures a rapid recovery after the pulse. Self-oscillation is prevented by an inductor B which may be in the form of a ferrite bead.
