Title: "multidimensional magnetic memory system"
IPC: G11C8/02
Filed: 1954-08-20
Abstract: 767,760. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 20, 1954 [Aug. 25, 1953], No. 24274/54. Class 106 (1). In a storage array of magnetic cores comprising word-lines of cores each having at least first and second word-line paths, the first wordline paths are interconnected to form a first group of word-line circuits, each including a plurality of word-line paths, and the second word-line paths are similarly interconnected to form a second group of word-line circuits, a unique word-line being selected by selecting a unique word-line circuit from each of said groups. An array of 4096 word-lines may be regarded as a three-dimensional array with 64 X-planes and 64 Y-planes, the word-lines, each having say 40 bits, extending parallel to the Z- axis. By selecting an X-plane and a Y-plane, a unique word-line may be selected. The group of 64 X-plane circuits may itself be represented as a three-dimensional arrangement, Fig. 3, in which each X-plane circuit extends vertically and is at the intersection of two planes taken respectively from two perpendicular sets of 8 planes each. Thus an X-plane word-line circuit may be selected by means of two address matrices 50, 52 each having 8 output leads. The leads 51 of the matrix 50 are connected to the upper ends of the word-line circuits and the lead 53 of the matrix 52 to the lower ends. A similar arrangement is used for the selection of a Y-plane. Thus in a single word-line only, both X-plane and Y-plane coils are energized. Word-bit selection within that line is effected by reversely energizing word-bit coils on those cores which are not to be reversed. All of the word-bit coils 63 corresponding to a given wordbit, e.g. the first, are connected in a single circuit. In a smaller array having 512 wordlines arranged in 64 X-planes but only 8 Y- planes, a single matrix is sufficient to select a Y-plane. Each cores preferably has 6 coils, a reading and a writing coil for each of the three planes. In one arrangement, Fig. 7 (not shown), the X-planes have separate reading and writing coils but the Y-planes single coils only. A diode address matrix having 8 output leads and controlled by three flip-flop circuits is described. Specification 766,189 is referred to.

Title: Improvements in gaseous fluid blast electric switches
IPC: H01H33/82
Filed: 1946-08-16
Abstract: 615,031. Gas-blast switches. ETABLISSEMENTS MERLIN & GERIN. Aug. 16, 1946, No. 24388. Convention date, May 5, 1939. [Class 38 (v)] In a gas-blast circuit-breaker a tubular movable contact 2 is surrounded with clearance by an annularmember 3, which may be either metallic or insulating according as the voltage is medium or high, and which is so spaced from the end of a fixed nozzle-contact 1, as to define a gas passage having a section substantially equal to the sum of the sections of the contact-bores. The member 3 is secured to an insulating - tube 9 which seals the end of an insulating-tube 7, and has a fluid-tight joint 13 through which the contact 2 slides. The breaker is opened by an insulating connecting-rod 23, at the same time as pressuregas, supplied over a conduit 10 and a recessed collar 8 arranged centrally around the tube 7, enters an annular blast-chamber 11 through spaced apertures 17. Owing to the clearance between the contact 2 and the member 3, the gas-pressure on the interior and exterior of the latter will be equalized, so that when the contacts separate the whole of the arc-gases will be exhausted through the contact-bores, and thereby prevented from coming into contact with the outer surface of the contact 2. Exhaust-orifices 20 in the contact 2 co-operate with a muffle 21, 22, which may be carried by the contact 2 itself or by the base of the tube 7, Fig. 2 (not shown).

Abstract: 1277689 Continuous casting; straightening CONCAST AG 20 May 1970 [20 May 1969] 24519/70 Headings B3E and B3F A withdrawal and straightening device, for a plant in which a cast strand 1 is conveyed from the mould in an at least partly curved path, has upper and lower banks 19, 20 of rolls, at least some of which rolls are driven, and at least two of the rolls 11, 12 or 11<SP>1</SP>, 12<SP>1</SP> of one of the banks are mounted in a unit assembly including a pivotable rocker, e.g. having a rocker arm 15 or 16 at each end of the rolls, to distribute loading. As shown in Fig. 2, a unit of two rolls 11, 12 in the upper bank of one section of the device is opposed to a unit of two rolls 11<SP>1</SP>, 12<SP>1</SP> in the lower bank of the section. The arms 15 of the upper rocker are movable to adjust the spacing of the opposed rolls by means of pistons (of cylinders 21) connected to the pivot pins 17 of the rockers. The pivotal range of the rocker 16 is limited by stops 27, 28. In another embodiment, Fig. 4, a section of the device (to be both preceded and followed by two sections of the kind shown) there are two pairs of rockers in the form of yokes 35-38 each mounting a pair of rollers. The upper yokes are each adjustable, for roll spacing, by a piston of a cylinder 41 or 42 at each side of the strand 1. Each bottom yoke 37 or 38 is connected to the cylinders 41 or 42 and the cylinders are movable in a supporting frame 23 and pivotably connected to a common third rocker 43. All but rolls 33, 34 are driven. The pivotal axis of the rockers 15, 16 of the middle section of the first embodiment, or of the rocker 43 of the middle section of the second embodiment, lies in the vertical plane through the tangent point 9 of the strand 1 and through the centre of curvature of the main guide path curve or that of the curved portion preceding the device. Particular sections of the device, e.g. having one rocker above and one below the strand 1, may be freely movable transversely of the casting path and of the pivot axes of the rockers, the distance between the axes remaining constant.

Title: Improvements in or relating to television systems
IPC: H04N3/32
Filed: 1933-09-04
Abstract: 427,625. Television. COSSOR, Ltd., A. C., BEDFORD, L. H., and PUCKLE, O. S., Highbury Grove, London. Sept. 4, 1933, No. 24526. [Class 40 (iii)] In a system using velocitymodulated scanning, a voltage, derived from the output of the photo-cell P and controlling the instantaneous rate of change of the scanning ray, is transmitted, and the integration to produce the voltage controlling the deflection of the ray at the receiver is carried out by a time-base circuit C1, V1, V2, V3 at the receiver. Transmitter, Fig. 1. Scanning potentials for application to a deflecting plate Px1 are developed across a condenser C1 by charging it through a valve V1 and discharging it by valves V2, V3, as described in Specification 419,298. The potential for the transverse scanning movement is developed across a condenser C5, which is given an increment of charge through a valve V5 each time that its grid is given a positive pulse through a condenser C15 by the discharge of the condenser C1. At the end of each picture the line scanning is interrupted for a time longer than the longest possible line by a relay S which short-circuits the pulse fed to the grid of the valve V3 and is controlled by a time-base circuit R13, C13, V14. This interruption allows the bias supplied by a circuit R5, C6 to the grid of a gas-discharge valve V6 to fall sufficiently to allow the discharge of the condenser C5 through the valve. A circuit V9, C9, V10 compensates for movement of a film as described in Specifications 399,469 and 412,794. The grid voltage of the valve V1 is taken as the signal for transmission, and a line-synchronizing signal is obtained by feeding the last anode circuit of the photo-cell amplifier from a tapping on a resistance R2. Residual picture distortion is annulled by introducing a compensating distortion between the grid of the valve V1 and the transmission voltage, Fig. 4 (not shown). Receiver. When operating on a " white " synchronizing signal, the receiver is similar to the transmitter with the receiving amplifier in the place of the photo-cell amplifier, Fig. 2 (not shown). When " black " synchronizing signals are used, the discharge of the condenser C1, Fig. 3, is under the control of a valve V4 with a screen voltage so low that anode current flows only on the receipt of a synchronizing signal. This causes the grid of the valve V3 to move negatively and so initiate a discharge. Potentiometers Ri, Rv are adjusted to the correct degree of intensity and velocity modulation respectively. Specifications 413,401 and 423,098 also are referred to.

Abstract: 1,213,732. 732. Optical projection apparatus; projection screens. W.S. MILLER. May 23, 1968 [June 13, 1967], No.24601/68. Headings G2A and G2J. An optical projection apparatus comprises a light reflecting structure 16 shaped as a conicoid, a first projector 15 constructed to project an object on to the structure and a second projector 17 located at a focus of the conicoid 16 and constructed to reproject the image on to a screen 10 which is shaped as a second conicoid having a focus at the location of the second projector 17. The second projector 17 is a spherically curved lens having its centre coincident with the focii of both conicoids 16 and 10. The conicoid 16 is an optical director positioned at the focus of the first image and has a surface with many small reflective facets (35) Fig.5 (not shown) in order to concentrate the light on the projector 17. The surface 29 of reflector 16 may be an ellipsoid, paraboloid or hyperboloid and the surface 33 of screen 10 may also be one of these surfaces, and may be formed from a large number of glass beads. Alternatively these surfaces may be spherical. Both surfaces 29 and 33 have a common axis of revolution 30 on which both the projection systems 15 and 17 are located. Alternatively the surfaces may be spherical. The first projection system 15 includes a mirror (25) Fig.4. (not shown) which is operated to select images from two different projectors (21) and direct them to a common location, and a relay lens 18 for producing a projection of either of the last mentioned images on the reflecting structure 16. Each projector (21) has a lens which produces an intermediate image at infinity and has a second lens 23 which produces through the mirror (25) an aerial image (24) of the intermediate images. The optimum viewing location is located on axis 30 at point 13. The apparatus is particularly useful in a cinema or outdoors.

Abstract: 967,330. Control of A.C. motors. CANADIAN CONTROLLERS Ltd. June 27, 1962, No. 24710/62. Heading H2J. A brake B is coupled to an induction motor which drives a hoist, the release coil 10 for the brake being energized from the rotor circuit of the motor. When a drum controller 12 is moved to the first hoisting- position, coil 10 is energized from three-phase rectifier 76-81 in the rotor circuit, so releasing the brake. A maintaining circuit for the brake is completed from rectifier 86 through resistors R22-R24, the rectifier being connected to the mains through a transformer. If contacts LS1, LS2, ofanover-hoist limitswitchare opened, the winding 10 is deenergized to set the brake. Movement of the drum controller to further hoisting-positions causes the rotor resistance to be removed in timed steps. The rotor is connected to supply D.C. to the stator in the first lowering-position of the controller, so providing a compensated braking torque due to overhauling of the motor by the load. Most of the rotor resistance is removed, and the friction brake is released. On further lowering- points of the controller, the rotor resistance is re-inserted to reduce the braking torque until the motor is reconnected to drive the load downwardly and the D.C. braking circuit is disconnected. Actuation of pushbutton 25 has the same effect as returning the controller to the " off "- position from a high-speed lowering position.

[Also in Division B8] The meeting faces 3, 4 of cartons which faces have previously been coated or impregnated with thermoplastic material are sealed together by applying heat simultaneously to the two faces 3, 4 from a source operating between them (otherwise than as described in Specification 898,960) and, as soon as the coating is sufficiently plastic to adhere, removing the heating effect and bringing the faces 3, 4 into mutual contact under pressure. The thermoplastic coating or impregnant is preferably applied to the whole of the carton material. A filled carton is conveyed to a heating station at which the faces 3, 4 are heated by two flame jets 6, Fig. 2, of gas, oil or spirit issuing from a double orifice burner 7 ; by radiant heat reflected from an infra-red source on to the faces 3, 4 by a hollow block 10, Fig. 4, fed by hot oil or water through inlet and outlet pipes 11 or by reflection from an adjacent resistance heater. The carton then passes to a closing and pressing station at which rollers press the faces 3, 4 together. Cooling means, e.g. cool air jets or chilled pressure rollers, may be provided at or immediately beyond the closing station. The invention may also be applied to sealing a wrapper around an already closed carton.
