Title: Interactive enquiry systems
IPC: G06Q10/00
Filed: 1976-03-17
Abstract: 1504112 Interactive enquiry system INTERNATIONAL BUSINESS MACHINES CORP 17 March 1976 10813/76 Addition to 1437883 Headings G4A and G4H In an interactive enquiry system comprising a host data processor 1 with associated central data store 2 connected to a plurality of local sub-systems 4 each including a local processor 7, a local data store 9, 17 and at least one enquiry terminal 13 for accessing data in store 2, each subsystem creates space in its local store by deleting those items obtained from the central store which are least frequently requested by its terminals, whereby in operation the most popular items requested in a particular subsystem may be accessed without accessing the host processor. The system is described as an improvement in the ticketing system of Specification 1,437,883, data being stored in "pages" corresponding to city pairs, &c. (Fig. 2, not shown), each terminal 13 comprising a display 14, a keyboard 15 and a printer 16 (Fig. 4, not shown). Each local store comprises a RAM 9 (42, Fig. 3) containing the most popular item and a floppy magnetic disc file 17 containing the next most popular items; a request from a terminal is used to access first RAM9, then disc 17, then store 2 (Figs. 6 or 9, not shown), although disc 17 and store 2 may be accessed simultaneously to save time. RAM9 may take the form of two push-down stacks storing pages in respective "quiterecently-used" and "least-recently-used" chains (Fig. 7, not shown); alternatively it may consist of a first part storing data and a second part storing directory entries (including frequency of use) for the items in the first part (Fig. 10, not shown). The boundary between the two parts may be floating, and free space in the first part may be periodically consolidated. The RAM may also contain a list of the most frequently used items together with their address on the disc, the list being scanned when an item is not found in the RAM. Disc 17 contains data together with directory entries which indicate, inter alia, frequency of use (Fig. 8A or 11, not shown), the least frequently used items being deleted to create space for a newly accessed item from store 2. Disc 17 also contains RAM back-up storage and storage which cannot be deleted containing items anticipated to be the most popular or essential for its particular subsystem. A directory entry may be stored on the same track as the associated item (Fig. 8B, not shown), when a hashing operation may be performed on a number identifying an item to determine the track(s) where it should be stored. Alternatively the disc may contain separate directory and data tracks (Figs. 13- 14, not shown). The frequency of use information for a stored page may take the form of a count which is incremented each time that page is accessed. Alternatively, each page is given a high count whenever it is accessed, the counts for all the pages being periodically decreased. Specification 1,504,113 describes and claims similar subject matter.

Patent GB-376833-A (GB)
Title: Improvements in or relating to artificial bristles, straw and similar products
IPC: D01F2/28
Filed: 1931-04-17
Abstract: Artificial bristles, straw, &c. of subdued lustre are produced by coalescing a number of filaments, straw, &c. containing a derivative of cellulose in the presence of a white or substantially white pigment or effect material.  The material to be coalesced may be in the form of fine filaments, twisted or untwisted, or consist of heavier filaments or bristles, or straw, braids, tapes or strips of fabric.  Pigment may be incorporated in spinning solutions for the filaments &c., or may be applied to formed filaments &c. prior to or simultaneously with the application of coalescing liquid.  Ornamental effects may be produced by incorporating with the artificial filaments &c. yarns of natural silk, cotton, reconstituted cellulose, wool or fine flat metal bands.  The cellulose derivatives are preferably organic derivatives, e.g. esters such as cellulose acetate, formate, propionate or butyrate or ethers such as ethyl, methyl or benzyl cellulose.  Suitable pigments include titanium dioxide, barium and strontium sulphates, barium calcium and strontium carbonates, barium, calcium, and strontium phosphates, zinc oxide or sulphide; also organic compounds of high melting-point such as acidyl derivatives of diamino diphenyl bases, e.g. diacetyl benzidine, diacetyl tolidine, condensation products of urea or thiourea and a diphenyl base, e.g. thio-carbo-benzidine, 4-4<1>-diureido diphenyl and 4-4<1>-dithio-diureido diphenyl, and a -dinaphthyl urea and diphenyl oxamide. Coalescing liquid for the filaments &c. contains a solvent or restricted solvent for the cellulose derivative.  Suitable solvents or solvent mixtures are acetone, ethylene dichloride and ethyl or methyl alcohol, dichlorethylene and ethyl or methyl alcohol. The coalescing liquid may contain a proportion of cellulose derivative such as specified above.  Coalescence may be effected by the liquid alone or may be assisted by heat and pressure.  The pressure device may comprise a pair of rollers at least one of which is heated.  In an example a 1,50 denier yarn of cellulose acetate composed of 40 filaments and containing 1 per cent of titanium oxide is wound while passing at a rate of 200 metres per minute over a wick which supplies acetone of 99 per cent strength in an amount equal to 20 per cent of the weight of the yarn; the filaments coalesce to form a white, matt, opaque bristle.  In a further example, the pigment is applied to the formed yarn as it is wound from one package to another, by means of a roller supplied with a 25 per cent dispersion of titanium oxide in diethylene glycol, followed by an application of 99 per cent acetone by means of a flannel wick.  Specifications 341,057, 346,678, and 346,793 are referred to.

Patent GB-494259-A (GB)
Title: Improvements in or relating to the production of crepe fabrics
Filed: 1937-04-23
Abstract: Fabrics containing high twist cr<\>zepe yarns of an organic ester of cellulose are treated with an agent having a hydrolysing or saponifying action on the cellulose ester yarns, and are thereafter treated with a cr<\>zepeing bath.  The treatment with the hydrolysing or saponifying agent, e.g. hydrochloric acid, formic acid, oxalic acid, caustic soda, caustic potash, or sodium carbonate, may be sufficient to cause a loss in weight of the materials of 20 to 30 per cent, but is preferably insufficient to destroy the affinity of the materials for cellulose ester dyestuffs.  After the treatment, the fabric is preferably dried and washed with warm water or soap solution prior to being subjected to the cr<\>zepeing treatment.  For the latter, a treatment with a hot aqueous soap solution at a temperature of at least 80 DEG  C. may be used, and the steps of hydrolysing or saponifying, drying, washing, and cr<\>zepeing may be carried out continuously.  In order to preserve the lustre of the fabrics, particularly after using caustic soda or sodium carbonate in the saponifying treatment, a salt or sugar, e.g. ammonium sulphate or cane sugar may be incorporated in the cr<\>epeing bath. Specifications 437,019, 438,589, 438,590, and 438,591 are referred to.
