Title: Improvements in or relating to pulse generating circuit arrangements
IPC: H03K3/16
Filed: 1959-05-05
Abstract: 911,409. Valve pulse generating and gating circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 5, 1959 [May 8, 1958], No. 15369/59. Class 40 (6). [Also in Group XXXVI] A self-oscillating pulse generator is controlled by input pulses of a much lower frequency supplied through two separate channels, the first channel inhibiting the pulse generator during each input pulse, the second channel discharging a relaxation capacitor in the pulse generator during each pulse so that the pulse generator is ready to start at the end of each input pulse. Fig. 5 shows a circuit for providing the trains of pulses Z from the line and frame synchronizing pulses l, b<SP>11</SP>. Frame synchronizing pulses b<SP>11</SP> are fed to the monostable multivibrator 12, 13, of which valve 12 is normally cut off but is rendered conductive by each positive pulse b<SP>11</SP>, maintaining valve 13 cut off for a time T1 1 depending on the time constant of components 16, 17. The end of period T1 is accurately determined by the appropriate line pulse l. The output pulses b<SP>1</SP>1 drive valve 2 into conduction, cutting off the blocking oscillator 1, the relaxation period of which is determined by capacitor 8 and resistor 9. Pulses b<SP>1</SP>1 also discharge capacitor 8 via a rectifier 5 thus ensuring that valve 1 is able to start generating the train of pulses Z immediately each pulse b<SP>1</SP>1 is finished. Small amplitude line pulses I are fed via capacitor 11 to synchronize the start of each pulse Z with the start of a line. The repetition frequency is stabilized by the catching diode 6 and is adjusted by variation of resistor 9. Pulses are derived from the pulses Z by means of a monostable circuit comprising valves 14, 15. The blocking oscillator 1 may be replaced by a free-running multivibrator.

Title: Improvements in and relating to means for erecting cartons
IPC: B31B5/76
Filed: 1939-05-24
Abstract: 529,200. Setting-up collapsed cartons. HARTMANN, C. W., and SATONA, Ltd. May 24, 1939, No. 15421. [Class 94 (i)] A machine for distending collapsed cartons comprises a reciprocating bar which is inserted in each carton in succession to support it while it is partly distended by a folding - member moving transversely to the bar, and means for opening the carton fully and feeding it on to a support. The carton, which is used for retailing liquids, comprises a blank 1, Fig. 1, to be folded into a square-section tube with sides converging to a folded base. The flattened blanks are stacked on a base 5, Fig. 2, in front of a feed plate 20 which is urged forwards by the frictional drive of an endless belt 24. The plate presses the stack against a raised stop 19 and a folding-member 17 carried by a bar 8. A spreader bar 7, attached to a reciprocating carriage 16, moves across the front of the stack, and in its forward movement enters the first blank and supports the back walls of the blank against the pressure of the plate 20. The bar 8 is carried by a pair of swinging arms 9, and when the bar 7 has entered the blank fully, the arms 9 swing the bar 8 about the bar 7. The folding-member 17, which overlaps slightly the front edge of the first blank, partly opens the carton, and this movement presents one corner of the carton to a pair of rollers 10, 11. As soon as the bars 7, 8 return to their initial position, the rollers draw the partly-opened carton between them and deliver it to a shaping-plate 13 between ,a fixed abutment 13 and a reciprocating pusherplate 14 which co-operate to open the carton fully. Finally, a flange 16a attached to the reciprocating carriage 16 pushes the distended carton on to a support for conveyance to further operating-stages.

Title: Magnetic device for storing information
IPC: G11C19/10
Filed: 1962-04-24
Abstract: 937,860. Circuits employing bi-stable magnetic elements. HUGHES AIRCRAFT CO. April 24, 1962 [May 25, 1961], No. 15567/62. Class 40 (9). [Also in Group XIX] A magnetic data store using domain shifting in a magnetic wire wound on a plate-like removable storage member comprises a holder 20 (Fig. 1) with slot 31 into which a storage member can be inserted, write and read windings 84, 86 fixed in the holder, and two domain-shifting drive conductors 98 and 100 of zigzag form, staggered relative to each other, and located round the slot, so that by suitably electrically energizing them a magnetic field can be caused to step the magnetic pattern of data entered at 84 along the wire for eventual read-out at 86. The plate is of electrically conductive material, and titanium is stated to be suitable when the wire is of metaliron since the similar coefficients of expansion ensure that a constant tension in the wire is maintained; this is necessary for maintaining its magnetic properties. A coating of shellac retains and protects the wire. Magnetization is along the axis of the wire; in one direction for binary 1, and in the other for binary 0 and also between bits. Transistor circuits are described for read circuit 178, write circuit 146 and domain shift driver 156 which is controlled by clock 166 in synchronism with the write circuit. Data read out can be re-written over line 182. Fig. 4 shows the drive conductors 98, 100 for domain shifting (in cutaway form) and the way the currents through them are switched in each of four clock times T 1 -T 4 . A " plus sign " indicates one direction of current in the corresponding limb of the conductor 98 or 100 at that clock time, and a " minus sign " the other. One bit is written in a length equal to that between successive limbs of the same conductor, and is separated from the next by an equal length of wire with reference magnetization the same as binary 0. In a cycle of four clock times the pattern is thus advanced sufficiently to write the next bit. Specification 857,289 is referred to.

Abstract: 1,198,235. Rocket assisted projectile or gun boosted rocket. A. I. MAGNUSSON, P. T. MARKLUND, S. M. BRODDNER, L. AX, and R. B. ANDERSSON. 26 March, 1969, No. 15774/69. Heading F3A. A rocket assisted projectile or a gun boosted rocket comprises a solid propellant charge 7 and a supporting tube 11 separated by an annular space 14 from the wall of a central bore of the charge, the charge showing a high tensile strain in response to axial and centrifugal forces set up by launching, whereby the charge is constrained by axial acceleration during launching to deform so a to receive support from the tube without cracking, but when axial acceleration ceases can resume its original shape and consequently form a space between the charge and supporting tube so that radial combustion of the charge is rendered possible. Centrifugal forces generated by spinning of the projectile cause elongation of the charge into engagement with the end walls of the combustion chamber with a consequential enlargement of the space between the charge and supporting tube. The space may be uniform or rearwardly tapered. The charge can be provided with a heat insulating lining along its outer surface 8 and end surfaces 9 and 10, and may be bonded to the casing along the rear one third of its length. The supporting tube is consumable during combustion of the charge and comprises glass fibre reinforced plastics material, phenolicasbestos laminate or magnesium and aluminium alloys. The propellant charge includes a carboxy-terminated polybutadiene binder and is ignitable by an igniter 15 located in a recess in a conventional shell case 1 or in a nozzle closure 16. A heat insulating layer of asbestos-phenolic laminate protects the shell casing.

Title: Improvements in the electro-osmotic separation of substances
Filed: 1920-06-10
Abstract: 144,710. Elektro-Osmose Akt.-Ges. (Graf Schwerin Ges.). April 8, 1918, [Convention date]. Electric endosmose.-Before the separation by electric endosmose of mixtures of colloids, ions, and non-ionized bodies, ions which are unsuitable for the process are replaced by more suitable ones, for instance chloride, sulphate, or phosphate ions by inorganic or organic ions of the samel or different valency, or calcium, magnesium, or aluminium by ammonium, sodium, or potassium. If a mixture containing ammonium sulphate and albumen is treated in a three-compartment cell, even the most electro-positive diaphragms do not prevent more rapid migration of the ammonium ions and consequent acidity of the mixture in the middle compartment; but after treatment of the mixture with barium acetate and removal of barium sulphate, the mixture on electrolysis with a positive diaphragm at the anode remains feebly alkaline and albumen is not precipitated. If barium chloride is similarly used, the mixture keeps feebly acid. Both anions and kations can be replaced; for instance, if aluminium sulphate is present, the aluminium can be replaced by ammonium and the sulphate ion by a monovalent one.

Title: Method of electron control
IPC: B41F31/28
Filed: 1938-05-26
Abstract: 518,665. Thermionic valves. JOBST, G. May 26, 1938, Nos. 15784, [Convention date, May 26, 1937], 15785, 15786. [Convention dates, June 1, 1937], 15787 and 15788. [Convention dates, Aug. 28, 1937]. [Class 39 (i)] A constant or modulated stream of electrons from a cathode is gathered into groups which reach the anode at regular intervals which are equal to or a multiple of the period of an oscillator circuit connected between the anode and cathode. Two methods of accomplishing this are described. In the arrangement shown in Fig. 1a electrons from a cathode 2 pass through a positively biased grid 3 to a grid 5. The grid 5 has a negative bias on which is superinduced an alternating potential such that the passage of the electrons is blocked for the greater part of the period, but during a short part of each cycle they can pass to the anode 8 ; in the interval, they oscillate between the cathode 2 and grid 5. In the arrangement shown in Fig. 2a two grids 23, 24 are provided, connected together so that the space between them is free of field. A potential increasing rapidly with the time and returning suddenly to its original value is applied to these electrodes so that electrons leaving the cathode 22 at a later period are accelerated more strongly in the space between the cathode and the electrode 23 than those leaving earlier and overtake them in the space between the electrodes 23, 24, so that they pass to the anode 25 in groups. It is stated that for the best effect the voltage applied to the electrodes 23, 24 should be proportioned to #o<2>/(#o-t)<2>, where #o is a constant and t the time but that a good approximation to this value can be obtained over a considerable part ot the period by means of a sinusoidal potential ; in the latter case the electron stream should be stopped by a grid carrying an alternating potential for that portion of the period when the approximation is not satisfactory. It is also stated that the cathode current may be modulated by a grid carrying an alternating current having a frequency less than that of the oscillating circuit, the frequency of the oscillations thus produced being increased in the ratio of the time in which a group of electrons leave the cathode to the time between the arrival of the first and last electrons of the group at the anode. The current may also be modulated by a frequency greater than that of the oscillating circuit. The application of the invention to a gas-filled tube, say at a pressure at or above 10<-5> mm. of mercury, is discussed.
