Abstract: 1,143,311. Electron beam focusing apparatus. SIEMENS A.G. 25 Jan., 1966 [26 Jan., 1965], No. 3225/66. Heading H1D. A magnetic system for focusing an electron beam along an axis-e.g. for a travelling wave tube-includes a plurality of permanent magnets magnetized in directions perpendicular to the axis and disposed in a closed row or rows along and symmetrically about the axis with similar poles adjacent the axis, the poles remote from the axis being linked by a magnetically soft bridging member which extends beyond the magnet at each end of the system to each of two magnetically soft irises, the individual magnets producing fields along the axis which are larger the nearer the magnet is to the centre of a row, and the field along the axis of the complete system reversing at the centre of the row or rows. A periodic focusing arrangement, Fig. 4, includes two or more axially adjacent systems defined by successive pairs of irises having a common pair of bridging members 2 from which an opposed pair of sets of hard ferrite magnets extend, the lengths of the magnets varying in a step-wise manner to a maximum at the centre of each system, such as to provide an axial field of substantially uniform intensity which reverses sense at each centre plane, V, and in the plane of each iris. In alternative embodiments, four sets of symmetrically disposed magnets are arranged around the axis (Fig. 2, not shown), or a single set constituted of annular disc magnets is used. Reference is also made to the production of non-uniform reversing fields by suitable variation of the magnet steps.

Convention date, Feb. 9, 1933. [Class 8 (ii)] Krypton and xenon are obtained from atmospheric air by rectifying air cooled to near its liquefaction point by washing liquid in amount sufficient to condense practically all the krypton and xenon, but less than sufficient to condense the maximum amount of oxygen ; the washing liquid may be about 10 per cent of the air treated. Air passed alternately through regenerators A<1>, A<2> and expanded in a turbine B is delivered at the bottom of a rectifier C. A part of the vapour evolved at the top of the column passes through exchangers G, F to a compressor E and back through the exchanger F. Part of this vapour is expanded in a motor H and delivered to the heating coil I of the rectifying column and thence to the top as washing liquid. Part of the remainder is liquefied in passing through the exchanger G and forms further washing liquid. The remainder passes to the heating coil of a column K which receives and partly vaporizes the residual liquid in the rectifier. The residual liquid in the column K is drawn off rich in krypton &c., which are extracted therefrom. The vapours may return to the rectifier C or a part may be drawn off as oxygen.

Title: Magnetic-domain storage system
IPC: G11C13/06
Filed: 1974-01-25
Abstract: 1450966 Magnetic bubble stores PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 Jan 1974 [12 Feb 1973] 03532/74 Heading G4C [Also in Division H3] Data is stored as stationary magnetic bubbles at particular positions in a plate of magnetic material. The particular positions are determined by recesses in the surface of the plate, the bubbles positioning themselves at these recesses. Write-in and read-out are performed by a beam of light. The light may be raster scanned over the plate, or the plate may be rotated relative to the light beam. In one arrangement there are a number of magnetic plated mounted on a substrate to form a disc. The plates have a regular array of dot-like recesses which lie on concentric tracks centred on the disc axis or on a spiral. The disc is situated in a bias field, which may arise from coils placed to one side of the disc and/or from a layer of permanent magnetic material deposited as a layer between the substrate and the plates. During write-in a polarized light beam, e.g. from a laser, is positioned radially to strike a required track on the rotating disc and, when a chosen one of the recesses is presented, a shutter passes the light to cause local heating to about the compensation point to form a bubble at that recess. The intensity of the light may be permitted to be insufficient alone to raise the temperature to the compensation point if an auxiliary heater is provided or if the bias field is temporarily reduced. During read-out the light beam is directed to a selected recess as in writein. The light reflected from the disc has a polarization which is rotated relative to that of the incident beam by an amount dependent upon the presence or absence of a bubble beneath the recess. The reflected light passes to a detector which outputs a 1 or 0 bit dependent on the polarization. The magnetic plate may carry an array of elongated recesses in addition to the datacarrying recesses. The elongated recesses are used to control the centring of the laser light beam on a selected track and the required data recess is found by counting the recesses as they pass the field of view. Alternatively the length of the elongated recesses may be indicative of their position. The elongated recesses and datacarrying recesses may be coincident.
