Abstract: 1,158,482. Magnetic storage apparatus. WESTERN ELECTRIC CO. Inc. 9 Aug., 1966 [9 Aug., 1965], No. 35586/66. Heading H3B. A magnetic storage device includes a pair of conductive strips P, N which lie on the surface of a piece of magnetic material having two stable remanent states. The conductive strips are joined by conductors having two parallelconnected portions 15A, 15B each including a photo-responsive region PCA, PCB. A potential difference is applied between strips P, N and one or the other of the regions PCA, PCB is illuminated so that current flows through portion 15A or 15B. The magnetic material beneath the region enclosed by loop 15 is therefore switched to a downward or upward stable state depending on which photo-conductive region was illuminated. A further layer of remanent or low reluctance magnetic material is placed over the conductors to provide flux closure paths. The information stored is read out by directing plane polarized light at the storage region and monitoring either the transmitted or the reflected beam, the plane of polarization of which is rotated in a direction dependent upon the direction of the remanent flux. The lower magnetic film is made of an optically transparent material in both cases, while the upper layer is either transparent or reflective depending on the mode of read-out utilized. Yttrium aluminium garnet having a thickness of between one and three mils is suggested for both layers, or gadolinium iron garnet may be used. An yttrium aluminium garnet laser may be used both for writing and reading, the beam being directed through a digital light deflector. Instead of a loop 15, with connecting tabs 16, 17, separate straight portions each containing a photo-responsive region may be provided. In a storage array conductors P and N each consist of comb-like structures with the teeth of each comb connected together at each end, the two structures being positioned so that the teeth are interdigitated. Both random access and wordorganized arrangements are referred to. The magnetic layers may be deposited by sputtering and the conductors formed by photo-etching. The photo-responsive regions may be of photo-conductive material such as cadmium selenide or may consist of avalanching diodes.

Title: Improvements in or relating to methods of forming internal coatings on hollow vessels
Inventor: MAJOR DONALD CECIL
IPC: B05D7/22
Filed: 1959-10-26
Abstract: 925,021. Electrostatic precipitation. GENERAL ELECTRIC CO. Ltd. Oct. 14, 1960 [Oct. 26, 1959], No. 36183/59. Class 39 (1). [Also in Groups XI and XV] A method of electrostatically depositing a layer of particulate material on the inner surface of a hollow vessel includes the steps of forming over the part of the surface on which the material is to be deposited a film of a conducting liquinol, establishing an electric potential between the film and an electrode positioned within the vessel and, before the film as dried, applying the particulate material to the surface charged in such a sense that it is attracted towards the film and forms a coating on the surface. The particulate material is the fluorescent coating of a bulbous HPMV lamp or a tubular lamp or a light-diffusing silica coating of an incandescent lamp. The envelope may be of glass or metal. In the method the bulb is sprayed with water containing 0.1-1% of a wetting agent such as " Teepol " or " Lissapol " (Registered Trade Marks), and the lamp is mounted in a rotatable holder 4 of the suction kind and drained to leave a liquid film. A glass tube 7 is introduced into the bulb. It contains a needle electrode 9 carried by wires 8 held by resilient metal bands 10 of part circular shape. A corona discharge is set up between electrode 9 and liquid film 12 and the fluorescent material which may be magnesium fluorogermanate is blown upwards through tube 7, e.g. as in Specification 925,023, while holder 4 rotates the envelope and the envelope or tube 7 is oscillated vertically or moved in one direction, the vertical speed being varied in accordance with the diameter of the envelope, as in Specification 925,022 by cam 13. The gas is blown upwards through glass fibre pad 27 and glass balls 28 which exert a milling action on the fluorescent powder. After the envelope is coated it is baked in an oven to dry it. The various operations may take place while the tubes are advanced along a single production line. The fluorescent or light-diffusing material may or may not be charged electrically, e.g. by friction before introduction into the vessel. The liquid may or may not have drained when the vessel is fitted over tube 7. A spring clip 5 provides a terminal for the liquid film.

Title: Microprogramme-interrupted computer
IPC: G06F9/26
Filed: 1975-09-04
Abstract: 1525862 Computer systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 Sept 1975 [7 Sept 1974] 36453/75 Heading G4A A computer system (Fig. 1) comprises a power supply unit SC and peripheral apparatus TA, MB connected by individual signalling lines DRE1, DRE2, DRE3 and a switch unit SA to the execution unit of a central processing unit CPU also including a non-volatile processing store MEM for macroinstructions connected to programme counter MPZ (pulsed from a clock TG) of a microprogramme store MPS. The switch unit SA is under the control of the execution unit. A priority sequence for the units SV, TA, TB exists with unit SV having highest priority and peripheral apparatus with little or no buffer capacity having next higher priority. As described the peripheral units are a keyboard TA and magnetic tape unit MB but they may include for example a printer, display, card reader and back-up store. Data is transmitted to and from the unit via switch S and bidirectional line DD. All microprogrammes include a section for interrogating the signal lines DRE1, DRE2, DRE3, there being predetermined maximum time durations between successive connections of each line to the execution unit to prevent loss of information. If a mioroprogramme (which may itself have been interrupted) is interrupted by a signal existing on one of the lines DRE, after the interrupt microprogramme has been completed, further execution of interrupted microprogrammes is carried out in order of priority. Initially at switch on of the power supply the programme counter is set to a predetermined address and pulsed by clock TG so that information stored in store MPS relating to peripheral apparatus is transferred to predetermined addresses in the store MEM. Next a test programme is performed to test the data paths, registers, ALU and core store. Line DRE1 is then interrogated to determine whether a signal from circuit AS exists indicating that a voltage monitoring unit U has detected an error in at least one of the generated direct voltages. If the signal exists a "terminate" microprogramme is fetched which marks instructions in the store MEM which have not yet been completed so that they might be executed when the computer is restarted. A microprogramme loop is then cyclically completed until the voltage is such that the clock pulse generator TG stops. This prevents any functions being incorrectly operated. Storage capacitors ensure that an adequate voltage exists long enough to perform these steps. During normal operation all the units are interrogated sequentially. At switch off of switch SS during interrogation of the lines the signal on line DRE1 results in the state of this switch being subsequently transmitted to the control unit to initiate an appropriate microprogramme section.
