Title: Improvements relating to circuit arrangements for cathode ray tubes
Inventor: HIRSHMAN CYRIL LEOPOLD
IPC: H04N5/21
Filed: 1947-12-31
Abstract: 656,603. Radio interference suppression. EDISON SWAN ELECTRIC CO., Ltd. Dec. 31, 1947, No. 35160. [Class 40 (v)] [Also in Group XL (b)] The effect of transient interference signals in input signals applied to a modulating electrode of a cathode-ray tube is eliminated by also applying the input signals above a predetermined level which is varied automatically in accordance with variations in the peak value of the signals to a further modulating electrode so as to oppose the modulation produced by the first modulating electrode. In one arrangement according to the invention Fig. 4 (Comp.), the input signals (television signals including transient interference signals) are fed to the modulating grid of a cathode-ray tube CRT from the junction point of load resistors R1, R2 in the anode circuit of a valve V1 (video amplifier stage in a television receiver) and signals are also fed direct from the anode of V1 to the cathode of CRT through a diode D1, the conduction level of which is determined by the biassing potential applied to its cathode from condenser C3 which is charged through a second diode D2 during the peak periods of the signals. The circuit constants R1, R2 are so selected that the signals fed to the cathode of CRT during the occurrence of the transient interference signals are just sufficient to oppose the effect of these signals of the grid of CRT. Other embodiments in which the compensating signals are fed to the modulator grid instead of to the cathode of the cathode-ray tube and in which the biassing potential for the diode D2 is derived from the anode of V1 via a cathodefollower stage so as to reduce the loading on V1 are described with reference to Fig. 3 (Prov.) and Figs. 5 and 6 (Comp.) (not shown). In a further embodiment, Fig. 7 (Comp.), a diode D3 supplies D.C. restoration both to the cathode-follower stage V<SP>1</SP> 2  and to the grid of the cathode-ray tube and a switch AB is provided for selecting one of two different timeconstants for the load circuit of the diode D2. In order to prevent the D.C. voltage supplied by D2 from following sustained interference signals when a high time-constant is employed (to prevent clipping of white peaks), the load circuit is shunted by a valve which is rendered conducting periodically (e.g. by means of pulses at line or frame frequency) so that the reduced resistance of the valve reduces the time-constant by a desired amount and prevents a voltage build-up (Fig. 8, not shown).

Title: Improvements in or relating to electrical transformers and inductances
IPC: H01F27/32
Filed: 1947-12-31
Abstract: 637,210. Transformers and inductances. PHILIPS ELECTRICAL, Ltd. Dec. 31, 1947, No. 35198. Convention date, June 21, 1941. [Class 38 (ii)] An electrical transformer or inductance has a voltage winding 6 insulated from a core 1 by insulating members 7, 8 which pass around the winding and are secured to the outer columns 3, 4 of the core so that the distance b between the winding and core, measured along the insulating elements, is greater than the shortest distance a therebetween. The winding is thus " in suspension " around the primary winding 5 and both windings are thus secured to the same core. Excessive electrostatic stresses in the insulating elements are consequently avoided.

Title: One-way braking device
IPC: B66D1/06
Filed: 1965-08-17
Abstract: 1,110,328. Screw-and-nut gearing; safety devices. J. B. POPPER. 17 Aug., 1965 [20 Aug., 1964; 3 March, 1965], No. 35245/65. Headings F2J and F2Q. A one-way braking or locking device for driving a machine-tool lead-screw, jack, hoist, motor-vehicle window or steering-gear, or for opening and closing the door of a pressure chamber, or safety control of a press, uses differential screw-threads with proportions and friction coefficients related by specified formulae to give a desired degree of braking or locking with a high forward drive efficiency (exceeding 50%) without the necessity for a high reduction ratio. The device comprises a permanently fixed member 15; a first rotatable member 19 axially fixed with respect to the member 15; and a second rotatable and axially movable member 12 having differential screw-threads 13, 14 engaging threads on the members 15, 19. In Fig. 2, the member 12 drives and is turned by a handle 22, to impart rotation to the member 19 which is the driven member and has pinion teeth 21 engaging a rack carrying a vehicle window. In Figs. 1 and 5, not shown, the first rotatable member (10) and fixed member (6) have coaxial external threads engaging threads inside a sleeve (1) forming the second rotatable member. In Figs. 6 and 7 (not shown), the driven rotatable member is the ball-threaded lead-screw of a machine tool, which, in Fig. 7, not shown, is the second rotatable member, and so has axial as well as rotary movement. The differential threads may be of the same or opposite hand and the friction and thread parameters are related by the specified formulµ to give either simple one-way braking or three different degrees of self-locking as follows.- In a first order self-lock, locking occurs whenever the output attempts to drive the input. A second order self-lock adds to the first order, self-locking when the output member is subject to an active torque and the input member attempts to drive it in the same direction as that torque. (In this case the input drive would be unable to lower a load which it had raised). In a third order self-lock no drive is possible until a drive is applied simultaneously to both input and output. In this last form the device may be used as the safety control of a press, requiring both hands of the operator on input and output to control the press.

A transmitting amplifier is provided with negative feed-back by means of a resistor R2 connected between the grid and a tapping-point on the anode circuit-as shown, the join of capacitors joined in series across the anode tuned circuit. According to the invention the resistance R i  in the grid circuit comprises, in addition to the internal impedance of the driving source, that of a resistor connected in series, the arrangement being such that the impedance of this additional resistor combined with the input impedance of the valve matches the internal impedance of the driving source. The resistor R 2  may be replaced by two resistors R a , R b  in series, a switch S being provided to earth their common point; in this way, if the value of resistors Ra, Rb is suitably chosen the feed-back may be removed, e.g. in setting up the amplifier, without altering the stage gain.

Abstract: 877,596. Stapling machines. FANFOLD Ltd. Oct. 19, 1959 [Oct. 27, 1958], No. 35339/59. Class 89(3) A rotary stapling machine comprises a wheel 26, Fig. 1, containing a plunger 56, Fig. 5, which co-operates with grooves 59 to form a recess into which a length of wire, carried by the wheel, is pressed to form a staple by an anvil 58 on a wheel 27. After rotation of the wheels to the position shown in Figs. 1, 5, a hammer 62 drives the plunger 56 to eject the staple to pierce sheet material S moving past the wheel. The staple limbs projecting underneath the sheet material are then clinched by means 66 at a speed greater than the speed of driving the staple through the sheet material. The means 66 includes jaws 75, Fig. 1A, pivoted at 76 and movable by a plunger 71, driven by a follower 72 on a lever 73 rotating on a shaft 68A driven from the input shaft 25 faster than the wheels 26, 27 which are mounted on shafts 28, 29 respectively, and also faster than the means 66 which rotates on the shaft 25. The wire stock W is fed by wheels on shafts 42, 43 through a guide 38, Fig. 12, against a stop 45, and is then cut by a blade 46 rotating with wheel 26. The cut length is carried on ledges 50 to the position where anvil 58 forms it into a staple. A spring finger 33, Fig. 4, prevents backward movement of the wire stock and is mounted in front of the feed wheels.
