Abstract: 838,270. Statistical records. WESTERN ELECTRIC CO. Inc. July 25, 1958 [Aug. 5, 1957], No. 24034/58. Class 106 (1). [Also in Group XL (b)] In an information storage system the information is stored by imparting any one of three or more light transmission characteristics to individual discrete areas of the storage slide or member. The slide depicted in Fig. 2 has four transmission characteristics, viz. opaque, transparent and two intermediate grey levels. The information is read out of the system by the circuit indicated in Fig. 3. Light from a flying spot scanner is directed to the required area by information applied in analogue form to the X, and Y plates of the C.R.T. The light passing through the slide is received by the photo-cell 24, the voltage produced being a function of the light transmission of that area of the slide. The voltage is applied to the three gate circuits 31, 32 and 33, biased by the reference voltages V3, V2 and V1 of decreasing amplitude. The operation of the gates and the associated flipflop circuits 36 and 37 is indicated in the table, Fig. 4, where the code values 0, 1, 2 and 3 refer to areas which are opaque, dark grey, light grey and transparent, respectively, and the output information is given in reflected binary form. The output of gate 31 is applied to F/F1 via a delay circuit 35 and triggers it to a condition opposite to that to which it has been set by the output of gate 33.

Title: Improvements in and relating to glass panels
IPC: F21V3/04
Filed: 1959-07-14
Abstract: 931,551. Laminates. A. M. MARKS, M. KAHN, and M. M. MARKS. July 14, 1959, No. 24214/59. Class 140. [Also in Group XX] A light-polarizing panel comprises glass flakes extending substantially parallel to one another and to the plane of the panel, the flakes being held together as a self-supporting structure, either by adhesive material or by being embedded in plastic material. Examples of adhesive material, applied in organic solution or aqueous emulsion and subsequently dried, are polyvinyl butyral, vinyl-pyrolidine / vinyl acetate copolymer, acrylic resins, acrylonitrile/ butadiene copolymer, polyvinyl-pyrolidine/polyvinyl methyl ether/maleic anhydride mixture; examples of embedding material are methyl methacrylate/styrene or /vinyl toluene, copolymers, polyvinyl acetate, cellulose esters, acrylonitrile copolymers and melamine-urea resins. A sharp change in refractive index occurs at the surface of the flakes. The flakes are such as are obtained from the fragmentation of a glass bubble, and preferably have a thickness of 5 microns and diameters of about 1/16 to 1/4inch. The natural slight curvature of the flakes 11 (Fig. 1) entraps air spaces between them, the glass-air surface providing the change in refractive index referred to above. The flakes may be secured together by dots of adhesive material 12. The panel may be enclosed between and bonded to two glass cover-plates, and sealed (Fig. 2, not shown), the bonding material being, for example, an epoxy resin. In the form of Fig. 3, each flake is coated with a film 21 of titanium dioxide, to give the sharp change in refractive index, the coated flakes then being embedded in a resin sheet 20. In Fig. 4 (not shown), the panel is attached to one face of an electroluminescent panel comprising a metal plate having light-diffusing, phosphor, and metal coatings thereon. Fig. 5 shows an arrangement in which air bubbles have been entrained in the plastic sheet embedding the flakes. A number, e.g. up to twenty, of such sheets may be secured together, for example by a styrene/polyester monomer copolymer (Fig. 9, not shown). Fig. 7 shows a glass sheet 39, to which is secured a flake-panel 10, and finally a fibreglass layer 40, such a structure having good sound-absorbing properties. Heat transmission is also reduced by such a flake panel structure. Specification 762,768 is referred to.
