Title: Method of and apparatus for Producing Embossed Thermoplastic Sheet
Inventor: FROWDE STANLEY CHARLES
IPC: B29C51/10
Filed: 1966-11-25
Abstract: 1,168,273. Embossing. IMPERIAL CHEMICAL INDUSTRIES Ltd. 20 Nov., 1967 [25 Nov., 1966], No. 52825/66. Heading B6J. A thermoplastic sheet is embossed by arranging the sheet to face the embossing surface of a non-porous embossing medium, applying suction to the space between the sheet and the embossing surface, forcing the sheet into intimate contact with the embossing surface by means of a flexible diaphragm, applying heat to the thermoplastic sheet and removing the embossed sheet from the embossing surface. As shown, Fig. 1, a thermoplastic sheet 6 (e.g. vinyl polymer or copolymer 1 lies between a flexible, non-pourous diaphragm 3 (of metal, silicone elastomer or plastics material), and the embossing surface of embossing medium 7 (of metal, silicone elastomer or glass). Air is evacuated simultaneously from compartments 1 and 2 and then air is admitted to compartment 2, thus forcing diaphragm 3, sheet 6 and medium 7 against heated surface 8. Air ie then admitted to compartment 1 to equalize the pressure and the embossed sheet is stripped from the embossing surface before or after cooling. Diaphragm 3 may be provided with an embossing pattern and may be used in place of or in addition to medium 7. In an alternative embodiment (Fig. 2) sheet 6 serves as the diaphragm and the embossing surface 7 is placed directly on top of it. In a further embodiment the embossing medium may be maintained in permanent contact with a heat source. Heating of the sheet and/or the medium may be effected by conduction or radiation or electronically. Sheet 6 may be provided with a supporting cellular layer of thermoplastic material.

Title: Information Retrieval System
IPC: G06F17/30
Filed: 1966-12-14
Abstract: 1,158,732. Information retrieval. INTERNATIONAL BUSINESS MACHINES CORP. 14 Dec., 1966 [29 Dec., 1965], No. 55902/66. Heading G4C. An information retrieval system includes sets of storage locations, each set identified with a different item of information (e.g. document), and each location of a set storing a given binary representation only if a corresponding keyword applies to the item identified with that set, the given binary representation also being stored in a " second " buffer location respective to the set if the first mentioned binary representation is absent from the set for a given keyword, and being stored in a " first " buffer location if it is absent from the "second." A magnetic tape has longitudinal tracks as follows: a clock track, M keyword tracks, and two buffer tracks. A fixed magnetic head is associated with each buffer track and a movable one can be positioned at any one of the other tracks. Each row of bit positions transverse of the tape is associated with a respective document, a " one " being recorded in each keyword track whose keyword is assigned to the respective document. Initially, both buffer tracks have a " one " at every position. Combinations of keywords, constructed with the connectors AND, OR and NOT, can be searched for, by scanning the relevant keyword tracks in turn, altering manual switches at the appropriate times to select the connectors used. The bits read from a keyword track are written in true or inverse form at corresponding positions on one of the buffer tracks, being thus effectively ANDed with the bits already there. The OR function is obtained as a combination of an AND and NOTs. The system automatically selects the appropriate buffer track, and writes the inverse of the second buffer track on to the first at the appropriate time if necessary. The documents having the required combination of keywords are finally indicated by " ones " in the first buffer track. The number of the first indicated document is obtained on a display counter by positioning the movable head at the clock track and pressing a manual switch. A second counter counts the clock pulses until it reads the same as the display counter, when the display counter counts " zeroes " from the first buffer track, stopping counting at the first " one " from the first buffer track, thus giving the document number. The second indicated document is identified by pressing the switch again, and so on.

The cooling plates 10 operate as in Specification 1,112,017; the grids 15 function as in Specification 1,354,758 for direct cooling of the casting; and the pressure chamber 20 is constructed as described in Specification 1,398,891. The seal 22 at the entrance to the chamber 20 is cooled and connected to the grids 15. Roller pairs 29, 30, 31 in the chamber 20 form a withdrawing and straightening means. A further withdrawing means is arranged after the chamber. An outlet valve 41 from the topmost of a number of compartments 24-27, into which the chamber 20 is divided, controls the pressure in the chamber and the released steam is condensed. The condensate and unevaporated water, drained by bottom valves 33 controlled by a level gauge, are recirculated to the nozzles 32. The relative pressures in the compartments 25-27 are controlled by valves 42-44. The casting direction may be vertical (with possible bending), inclined or horizontal.

Abstract: 1408876 Associative memories GENERAL ELECTRIC CO Ltd 24 Nov 1972 [3 Dec 1971] 56229/71 Heading G4C [Also in Divisions H3-H5] In an exchange, an associative i.e. content addressable, memory is used for storing data relating to the lines and trunks which have appearances on the exchange switching network. General description.-Each line has one word of memory comprising one row of bi-stable storage cells 12. A word is addressed by setting up each bit thereof-or more usually each bit of one data field thereof in the match and mask bi-stables 34, 36 of each column whereby any row word not having the set-up bit combinations will cause its output match bus 22 to be marked thereby preventing the match toggles 58 from operating when a match pulse is applied on lead 54. The toggles are connected in a chain of AND/OR gates 62, 64 which operate in the manner of a lock-on chain such that only the highest AND gate 62 is opened. The processor can interrogate the particular word indicated by the enabled AND gate by marking lead 72 whence, via gate 70, an enable signal is applied to one address wire 18 and thus each output gate 28 associated with this wire is permitted to pass the contents of its bi-stable cells 12 to an associated output register 38. In some circumstances a memory word may be addressed non-associatively.
