Title: Read only memory
IPC: G11C13/04
Filed: 1970-05-27
Abstract: 1317456 Read only memory OPTICAL MEMORY SYSTEMS Inc 27 May 1970 [5 June 1969] 25429/70 Heading G4A The invention relates to an optical read only memory. A plurality of light sources E1 to E16 such as galium arsenide or galium phosphide photoemissive diodes are arranged in a matrix and a plurality of light sensors are arranged spaced from the sources such that each source is coupled to each sensor by a plurality of separate light paths. A mask having a plurality of areas equal in number to the number of sources is situated between the sources and sensors with the areas associated with the sources such that the light paths between a source and all the sensors pass through only through the area associated with the source. Each area is divided into portions equal in number to the number of sensors each portion being opaque or clear to block or pass light to an associated sensor (as shown in Fig. 1 in the area associated with source E2). The sources may be coupled between rows and columns of an address matrix so that any source may be selected and the sensors may be similarly coupled or may feed amplitude detectors and amplifiers. The sensors may emit current on receipt of light or may change resistance. The sensors may be situated on the surface of a sphere having the sources distributed on a matrix arranged at the sphere centre (Fig. 2, not shown).

Abstract: 736,227. Cathode-ray tubes. LICENTIA PATENT - VERWALTUNGS - GES. Oct. 10,. 1952 [Oct. 19, 1951], No. 25456/52. Class 39 (1). An image intensifier tube for X-ray pictures comprises a semi-conductive layer 2 on a metal backing of which the conductivity varies according to the incident X-ray intensity or according to light intensity from an X-ray image on a luminescent screen, and the metal backing is held at the potential of cathode 4 so that electrons. therefrom are variably reflected by the semi-conductive layer and form an intensified image on luminescent screen 3. The first luminescent screen referred to may also be inside the tube envelope. It is stated that the semi-conductive layer may be of selenium, or the oxides, sulphides, selenides, tellurides, carbonates, sulphates and chlorides of Zn, Cd, Hg, Pb, Sb, Bi, Tl, Cu, Ag, Mn, or conventional fluorescent materials such as the above-mentioned sulphides and is formed by evaporation or deposition from suspensions. They are given a high transverse resistance, e.g. by forming them as a mosaic of electricallyinsulated elements. The layer thickness is 10<SP>-3</SP>-1 mm. CdS, CdSe and CdTI are stated to be most suitable for excitation by light from the intermediate fluorescent screen. In the form shown. the electrons pass through a small hole 5 in luminescent screen 3 and are accelerated by anode 6 to 2000 volts before being reduced to cathode potential at layer 2. The electron paths to the layer may be made curved by magnetic or electric deflecting fields. A second anode 7 has a variable voltage of 10-100 volts to enable the final image size to be enlarged or reduced. It is stated that due to the velocity distribution in the beam some electrons will always strike layer 2. A prior art image transformer using a semi-. conductive layer for forming an image of an object. illuminated by or emitting infra-red rays, is referred to.

Patent GB-261280-A (GB)
Abstract: 261,280. Jackson, L. Mellersh-, (Diago, F. G.). May 13, 1926. Voting-apparatus. - A ballot voting machine for registering votes given at elections by the gravity action of voting balls comprises a number of receptacles arranged in longitudinal and transverse rows, each receptacle being provided with a hole for the passage of a voting ball that has been inserted in one of a set of containers mounted above the receptacles on transparent bands adjustable to select the political party to which the vote is to be accorded. Arranged beneath the receptacles are sets of trays through which the bail passes and thereby moves the trays longitudinally to close the holes and prevent the insertion of another ball. As shown in Figs. 4, 6, and 12 several receptacles 2 - - 5 one for each party are connected by pin-and-slot connections and each has a number of holes 9 according to the number of candidates. The receptacles are furnished with guides 14, Fig. 12, and form passages for bands 15 which pass over pulleys 18 and are connected to weights 17. The bands are made of mica, celluloid, or other transparent material or they may be built up of strips of glass linked, or jointed together. Each band is provided with a container 19 having a pivoted trap 21 for the reception of the voting-ball. Under each hole 9 of the receptacles 2, &c. is a tray 25 made as light as possible and those in each transverse row are connected by links 26. Holes in the trays 25 register with the holes 9 and the voting ball in its passage through the holes falls upon an arm 30 of a lever 27 the other arm of which is thereby moved into engagement with the tray 25 and moves the latter to close the row of holes. At the same time the ball enters a corresponding tube 41, Fig. 18, and actuates an oscillating lever 71 connected by a rod 73 to a double armed lever 74 and pawl 76 of a corresponding counting mechanism 78, 83. The total number of 'votes is registered by a counter the actuating lever of which has a pin overlying the bent ends of the rods 73. Return of the trays to normal position is effected by a cam 52 mounted on rods 54 pivoted to a platform 47 upon which the voter stands and which remains depressed during the time he is registering his vote. Normally the container 19 for a " straight" vote is the only one exposed, the remainder being covered by a shutter 45 slidable in guides 44 on the casing. To expose the other containers for a " split " vote the shutter is pushed to the rear and is held by a bar 61 thereon engaging a latch 53 operated by an extension 51 of the platform 47. After the platform rises the shutter 45 is released and returns to normal position by the action of a cord and weight 62. To the upper row of trays is attached a rod 31, Fig. 20, so that when a vote is registered in this row the trays cause a movement of all the other rows to close all the holes 9. By means of other rods 85, 87 movement of any one of the other rows of trays causes a movement of the remaining rows.
