Patent GB-694503-A (GB)
Title: Improvements relating to thermionic valve trigger circuits
Inventor: HADFIELD LLOYD DYSON
IPC: H03K3/08
Filed: 1950-07-22
Abstract: 694,503. Pulse and saw-tooth generating circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 23, 1951 [July 22, 1950], No. 18351/50. Class 40 (vi). A cathode coupled two-condition circuit which has at least one unstable condition comprises a capacitor coupling the anode of a first valve to the control grid of a second which is also connected via two separate resistances to two different potential sources, one such path including a switching device which is controlled in dependence upon the condition of the trigger circuit so that the period for which the circuit remains in each of its two conditions is in part determined by the respective values cf the two resistances. Fig. 1 shows a multivibrator in which if valve 1 has just ceased to conduct then valve 2 commences to conduct and its grid potential rises rapidly. Diode 8 is thus cut-off by the rise in its cathode potential and capacitor 6 charges via resistor 7. The grid potential of valve 2 thus falls linearly until the valve is cut-off when valve 1 is rendered conducting and the grid potential of valve 2 falls rapidly again until diode 8 conducts when capacitor 6 discharges through a path comprising resistor 9, until valve 2 conducts when the cycle is repeated. A saw-tooth type waveform as shown in Fig. 2 is thus produced at the grid of valve 2, the sloping portions 16 and 18 of which produced when valves 1 and 2 are non-conducting are of a slope determined by the values of resistors 7 and 9 respectively, resistor 9 having a small value compared with resistor 7. The multivibrator may be synchronized by pulses applied to capacitor 12 or to the anode circuit of valve 1 or the constants may be adjusted so that the circuit functions as a pulse frequency divider. The circuit may thus be used as a saw-tooth voltage generator or pulses may be derived from output lead 11. In a modification, Fig. 3 (not shown), output pulses of opposite polarity are obtained by reversing the polarity of the diodes and their resistive connections to HT+ and HT -. Fig. 4 shows a further modification in which pushpull output potentials may be taken from leads 11 and 24 and in which the linearity of the saw-tooth voltage of the grid of valve 2 is improved by feed-back to its cathode via resistor 19 and capacitor 22, the saw-tooth also being maintained at constant amplitude. The duration of the long flank 16 (Fig. 2) of the saw-tooth voltage and hence the repetition frequency may be adjusted by variation of resistor 21. The potentiometer 23 may be adjusted so that the circuit operates as a single stable state flip-flop triggered by pulses applied to capacitor 12.
Patent GB-768024-A (GB)
Title: Improvements in and relating to clothes washing machines
IPC: D06F37/30
Filed: 1953-07-03
Abstract: 768,024. Washing-machines. GENERAL ELECTRIC CO. July 3, 1953 [July 18, 1952], No. 18497/53. Class 138 (2). [Also in Group XXIV] A washing-machine comprises a spin basket containing an agitator, a gear casing 23 provided with an annular hub 22, a gear frame 21 in the casing connected to the spin basket and provided with a hub 21a rotatably mounted in the hub 22, gearing carried by the gear frame 21 and connected to the agitator, a pinion 29 on a drive-shaft 31 for turning the gearing, the hub 21a having annular surfaces 44, 43 aligned with annular surfaces 48, 47 on the drive shaft 31 and hub 22 respectively, and two oppositely wound helical springs 46, 45 lying against the aligned surfaces respectively, which springs upon rotation of the drive-shaft in one direction are unwound to loosen the engagement between one spring (46) and the drive-shaft 31 and tighten the engagement between the other spring (45) and the hub 22 so as to hold the gear frame 21 stationary and effect operation of the agitator, and upon rotation of the drive-shaft in the other direction are wound to tighten the engagement between the one spring 46 and the drive-shaft 31 and loosen the engagement between the other spring 45 and the hub 22, thereby to release the gear frame 21 for rotation by the drive-shaft to effect rotation of the spin basket. The spring 45 has an outwardlyturned upper end 50 positioned in an opening 51 in the hub 21a. The spring 46 has an inwardlyturned upper end 52 positioned in an opening 53 in a liner 34 fixed by a pin 35 in the hub 21a. Both springs are formed from rectangular wire and pre-wound tightly. When shaft 31 turns in the direction of arrow A a collar 49 keyed to shaft 31 over-rides spring 46 which is wound left-hand, and pinion 29 effects oscillation of the agitator. Any torque tending to turn gear frame 21 is opposed by the braking action of spring 45 against the inner surface of hub 22, spring 45 being wound right-hand. When shaft 31 turns in the opposite direction (as indicated by arrow S) the tendency of collar 49 to turn relatively to spring 46 is in a direction which ,serves to wrap the lower end of spring 46 tightly around the collar, thus locking the collar and shaft 31 to gear frame 21 to effect rotation of the gear frame and its gearing, and the spin basket as a unit. As hub 21a rotates it tends to wind up the spring 45 so that its lower end no longer grips the inner surface of hub 22. The shaft 31 may be connected to a reversible electric motor (not shown) through a pulley 40, belt 54, and a bi-directional centrifugal clutch (not shown) which transmits drive when the motor, rotating in either direction, reaches a predetermined high speed. In a modification (Fig. 5, not shown) the helical springs, instead of both being arranged in a recess in the gear frame hub 21a, are arranged on opposite sides of this hub and bear against opposed faces thereof. Specification 684,656 is referred to.

Abstract: 1,011,663. Paperboard. L. N. EGERSTRAND. May 15, 1962 [Sept. 18, 1961], No. 18714/62. Heading D2B. [Also in Division F4] Hardboard is made by pressing a wetlap in apparatus which comprises two facing horizontal platens (5 and 6), adapted for heating (e.g. by steam lines 5a and 6a) and means for forcing the platens together to compress awetlap (13). One of the platens carries a flat, perforated plate (14) which, in use, engages the wetlap, and has a structure (12) behind it supporting the plate unyieldingly on the platen but permitting free egress laterally between the plate and the platen of moisture and steam passing through the perforations from the wetlap. The perforations are small and few enough and so arranged as to restrict the escape of moisture and steam uniformly across the layer. As shown, the other platen carries an imperforated plate 10. Both plates are of stainless steel and are backed by screens 9 and 12 having apertures closer together than perforations in the plate 14. This screen 12 forms the supporting structure referred to above. The finished board has one surface smooth, but the other surface has small projections widely spaced over it. These can, if desired, be sanded off.
