Title: Inductive component
IPC: H01F17/04
Filed: 1967-09-13
Abstract: 1,203,948. Transformers and inductors; magnetic storage devices. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 13 Sept., 1967 [30 Sept., 1966], No. 41724/67. Heading H1T. An inductive circuit component, e.g. a transformer, inductor, magnetic switching element or storage element, comprises one or more windings encased by one or more layers of a metallic magnetic material forming a magnetic circuit linking the windings, there being a gap in the layer or layers so as to render it or them electrically discontinuous in the winding direction. As shown, the primary and secondary windings 1, 2 of a transformer are covered with an insulating layer 3, and enclosed in metallic magnetic layers 4, 5, 6 separated by insulation 4a, 5a, an air gap U1 being provided to reduce eddy currents. An inductor (Fig. 2, not shown) comprises spiral windings (8, 9) photo-etched out of a copper layer applied to an insulating plastics foil (7), the windings being on opposite surfaces of the foil and with the same winding sense about a window (10) in the foil. Applied over the windings is an insulating layer, followed by a magnetic layer provided with an air gap (U2). The windings may be connected in series. Several such flat inductors may be stacked together with a magnetic layer embracing them all round the outside. Another application of the invention is described (Figs. 4-6, not shown). The substrate can be ceramic with screen-printed and fired-on conductors. The magnetic layers may be applied galvanically, electrochemically, electrolytically or electrolessly, several methods being described. The insulating layers may be applied by lacquering, e.g. electrophoretic lacquering, or these layers may be derived from copper, deposited electrolessly and subsequently converted to its oxide by wet chemical processes, or an insulating glaze can be used. The thickness of the magnetic layers applied is matched to the frequency range and particular application of the component, examples being described. The material of the magnetic layers may be iron-nickel alloy or highly permeable alloys of the permalloy type, and the method and conditions of deposition will depend on the desired characteristics of the layers. The inductance can be measured continuously during manufacture, and deposition of magnetic material halted when a desired value is reached. A control magnetic field may be produced during manufacture by passage of current through the component.

Abstract: 1358128 Self levelling headlamp systems DAIMLER-BENZ AG 22 Sept 1972 [2 Oct 1971] 44036/72 Addition to 1333509 Heading F4R In a pneumatically operated self-levelling system for vehicle headlamps, as described in Specification 1,333,509 further elements are introduced to improve system reaction to acceleration and braking. The system includes in addition to a pressure modulator 1, adjusting motors 11, 20 and a control switch 17 of Specification 1,333,509 a valve 41 inserted into a pipeline 21 between the control switch 17 and the adjusting motor 20 to by-pass the damping effect 40 previously introduced into the pipe-line to suppress fluctuations in the vacuum. This damping effect causes undesirable inertia in the system during acceleration and braking, and the valve 41 removes this. The valve may be electrically operated via a sprung pendulum switch 50, the pendulum 48 making contact with contacts 46 during harsh braking or accelerating, so operating the valve. In an alternative embodiment, the valve may be operated by a mercury switch on acceleration and by the brake light switch on braking.

Abstract: 1413401 Influenza vaccines MOUNT SINAI SCHOOL OF MEDICINE OF THE CITY UNIVERSITY OF NEW YORK 24 Sept 1973 [25 Sept1972] 44690/73 Heading A5B [Also in Division C6]  A recombinant, antigenically hybridised virus contains a haemagglutinin antigen having substantially no cross-reactivity with a challenge influenza virus and a neuraminidase antigen having substantial cross-reactivity with the challenge influenza virus, the recombinant being derived from viruses which are non- neurovirulent. The neuraminidase antigen may be derived from a subtype of Type A, B and C influenza viruses or from the Hong Kong variant. The haemagglutinin antigen may be derived from A/equine 1 virus. A recombinant virus H/eq 1/N2 which is effective against the Hong Kong variant can be formulated by recombining an Ao influenza virus e.g. Ao/PR 8/34 (HON 1) with the Hong Kong variant e.g. HK/Aichi/68 (H3N2) to form hybrid recombinants, some of which contain haemagglutinin and neuraminidase antigens which both have cross-reactivity with the type of influenza virus against which the viral vaccine is to be effective.

Title: A magnetic memory
IPC: G11C5/04
Filed: 1967-10-02
Abstract: 1,130,498. Magnetic data storage apparatus. NATIONAL CASH REGISTER CO. 2 Oct., 1967 [24 Oct., 1966], No. 44720/67. Heading H3B. A magnetic memory unit includes a pair of parallel sheets 10a, 10b of magnetic material having between them a plurality of parallel magnetic rods 15, each comprising a substrate coated with a magnetic thin film and surrounded by a solenoid winding 16, and a plurality of electrically conductive wires 12 arranged between one of the magnetic sheets and the magnetic rods, the wires being parallel to each other and transverse to the rods. Preferably wires 12 are provided between each magnetic sheet and the magnetic rods, the wires lying in grooves on the sheets and being continuous from one sheet to the other. In the arrangement shown, including a plurality of memory units, the wires 12 are also continuous from one unit to the next. In a modification the magnetic rods are also embedded in grooves. Construction.-A memory arrangement is constructed by arranging grooved magnetic sheets side by side and laying conductors along the grooves continuously across the adjacent sheets. Magnetic rods are placed on alternate sheets and the conductors extending between adjacent sheets are then bent so that the sheets can be stacked as shown in Fig. 8. Preferably, circuit boards 19 carrying line diodes 21, drivers 22 and decoding circuitry 23 are attached to magnetic rods 15 before placing the rods on the sheets. Operation.-Solenoids 16 are connected in rows and columns to row grounders and column drivers, to supply word read or write currents to a selected solenoid. Each bit is. stored in two adjacent storage elements on a common magnetic rod. In a complete memory assembly two units of the kind shown in Fig. 8 are used, the digit-sense conductors 12 of the two units forming separate series circuits, AC and BE (Fig. 13), for the first storage element of each bit, and FH and GJ (Fig. 14, not shown) for the second storage element of each bit. These circuits are connected to transformer windings 51, 52 (Fig. 15) and to drivers 40 and 60. During read-out a signal is induced in conductor AC or GJ if a "1" is stored or in FH or BE if a "0" is stored, a binary digit being represented by one or other of the two elements being switched from its datum state. Data is written by generating a digit current 2I D  in driver 40 or 60, and preferably a simultaneous inhibit current - 2I D  in the unselected driver. The word and digit drive currents have a magnitude such that only partial switching takes place. Read-out may be destructive or, if a smaller read current is used, nondestructive. The memory may be used to store ternary data, two of the memory states being represented by partial switching of one or the other storage element and the third state by switching of neither element.
