Abstract: 1,269,454. Electrolytic data storage. MESSERSCHMITT - BOLKOW - BLOHM G.m.b.H. 1 May, 1970 [23 May, 1969], No. 21126/70. Heading G4C. An electrolytic store comprises a number of polarizable storage electrodes 23, a non- polarizable counter electrode 24, and a non- polarizable auxiliary electrode 27 all contained in an electrolyte solution 25, and a junction contact 21/22 which may be selectively rendered conductive by means of, e.g. an addressable electron beam 14 in order to connect external source, 16, and discharge lines, 40, to respective storage electrodes. Constructional details.-A suitable junction contact is illustrated in Fig. 3. A highly conductive layer of, e.g. silver is formed on top of one or more highly insulating layers 62 of, e.g. metal oxides, and 63 of highly pure semi-conductor, e.g. silicon. One of the layers, 63, supports several basic elements 60 which are insulated from each other and form metal oxide silicon field effect transistors with the layers 62. The storage electrodes are identified by the numeral 65. In operation.-Address signals provided by, e.g. a computer direct the electron beam 14 to the appropriate part of the memory. The electrons cause the junction contact 21/22 to become locally conductive and an appropriate current flows by way of line 16 on to the corresponding storage electrode 23. Charges flowing to counter electrode 24 generate a polarizing potential across the junction of the storage electrode 23 and the electrolyte 25. Three conditions of polarization are possible, viz. positive, negative, and zero. For read out the beam 14 is appropriately addressed and a meter 40 measures the voltage between an auxiliary electrode 27 and the junction contact 21/22. During readout the polarization at the addressed storage electrode is regenerated via amplifier 50 and line 16 as above.

Abstract: 1,220,621. Laminating apparatus. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 6 May, 1968, No. 21342/68. Heading B5N. A method of laminating at least two sheets capable of being adhesively united under pressure comprises feeding the sheets, e.g. 1, 2, between two opposed pressing elements 9, 10 providing substantially parallel pressing surfaces, at least one of which elements, e.g. 9, oscillates at a frequency between 10 and 1000 c/s in a direction substantially normal to the sheets, the sheets being compressed in consecutive but overlapping sections thereof. In one apparatus shown for performing the method sheets 1, 2 are fed via heaters 23, 24 to the passage between a fixed element 10 and a vertically oscillated element 9. The sheets are advanced by belts 25, 26 at such a rate that the portions compressed between the elements 9, 10 in successive cycles overlap. In a second apparatus both loading elements are connected via spring elements to vertically oscillating members with the result that the elements when pressed together first compress the sheets passing between them and then advance the sheets before being released therefrom. In a further apparatus both loading elements are arranged for oscillation in two directions i.e. normal to the planes of the sheets and parallel to their direction of motion. In this apparatus the elements are actuated to compress the sheets, advance the compressed sheets, release the compression, and return to their original position. In further apparatuses the loading elements comprise a rotating roller and an oscillating element having a concave surface co-operating therewith, or an oscillating roller and a co-operating fixed element having a concave surface, or two fixed blocks in the surface of one of which is embedded an inflatable element the interior of which is connected to a pneumatic or hydraulic source of oscillating pressure. In all the apparatus except the last the oscillations may be produced by mechanical, hydraulic, pneumatic or electromagnetic means and the loading elements may be supported by elastic means. The lamination may be in selected areas only e.g. along stipes, and this may be effected by using divided loading elements. The apparatus may include cooling and/or drying means to consolidate the adhesion between the sheets. The sheets may be of thermoplastic or thermosetting plastics combined with each other or with sheets of metal, paper, wood, or mineral composition. They may be in the form of film, fabric, non-woven fabric, board, veneer, or laminates. Their surfaces may be impermeable or permeable, smooth, or rough. In one example a plastics foam is laminated between two paper sheets. The sheets may be held together by adhesive sprayed or coated on to their surfaces, or, when of thermoplastics material, by heating such material.
