Patent GB-615314-A (GB)
Title: Crinkled fabrics and methods of producing same
IPC: D06Q1/08
Filed: 1945-08-17
Abstract: Crinkled areas are produced on cloth of normal non-creping twist and texture by bleach processing and stretching the cloth in a warpwise direction, printing it locally in the warpwise stretched condition with a paste containing a thermosetting resin resist, drying, polishing and glazing the dry cloth and hardening the resin by heat while the cloth is held in the prestretched condition and finally subjecting the cloth to a slack laundering operation or mechanical shrinking operation, whereby the non-printed areas are shrunk to their prestretched dimensions and the printed areas are caused to crinkle.  Specified resists are urea-formaldehyde and melamine-formaldehyde condensation products and alkyd resins such as a glycerolphthalic-anhydride-fatty acid condensation product.  A blend of melamine-formaldehyde resin and an alkyd resin is also suitable.  If desired, the paste may contain urea and the printed fabric is then subsequently treated with aldehyde to produce the resin.  Thickeners such as starch, sodium alginate, gum tragacanth, a protein thickener or a resin-oil-water emulsion may be added to the paste as also may a polymerization catalyst such as ammonium chloride.  The polishing and glazing operation is effected by heated calendering rolls and this operation may also serve to harden the resin.  In the slack laundering operation the cloth is subjected to a standard soap and water laundering treatment and dried in the slack condition. The mechanical shrinking operation is that known under the Registered Trade Mark "Sanforized".  The cloth may be dyed prior or subsequently to the treatment or dyestuffs may be incorporated in the printing paste.

Abstract: 899,820. Focusing view-finders; optical projection screens. HEIDECKE, R., and FRANKE, H., [trading as FRANKE & HEIDECKE.]. July 7, 1958 [July 11, 1957], No. 21672/58. Classes 97(1) and 98(1). In a photographic camera focusing screen in which the direction of light scatter is controlled by forming the surface with conical or pyramidal projections or indentations, the cones or pyramids further from the centre of the screen are proportionately more inclined than those nearer the centre so that the divergent image forming beams are converged to the eye position on the central normal. Preferably, triangular pyramidal indentations of equal apical angle have their apices spaced apart in a plane by 20-40Á and their axes convergent to a point about half-way between the screen 9 and the eye position 14 or a position intermediate the eye position with and without a magnifying lens. A Fresnel lens may be added to the screen 9 when a very short focus magnifying lens is to be used. The screen is preferably made of polystyrol and each indentation is formed separately by a steel embossing tool formed with a pyramidal working face 30, 31 and 32. The angle of inclination of the tool is varied to vary the inclination of the pyramids and the smallest face 32 of the pyramid is always directed away from the centre of the screen. The opical angle of the pyramids or cones may be increased towards the edge of the screen. Specification 706,741 is referred to.

Title: Data processing systems
IPC: G06F11/34
Filed: 1972-05-10
Abstract: 1336704 Data storage; error detection INTERNATIONAL BUSINESS MACHINES CORP 10 May 1972 [9 June 1971] 21691/72 Headings G4C and G4A A digital data processing system comprises a data processor 23 and a number of dynamic data storage devices 1, the processor being adapted to monitor errors in the devices. Errors may arise in the storage volumes themselves (e.g. detachable disc or tape units) or in the drives which hold them, and, by monitoring the errors, the processor can amass data which indicates which volume(s) or drive(s) is erroneous.  For each device there is a group of usage/ error counters (Fig. 3, not shown) which count the number of seeks, the number of information bytes read (i.e. the usage parameters); the number of correctable data errors, the number of uncorrectable data errors and the number of seek or access errors/drive. A threshold of a minimum usage for a number of errors can be established and, if the error threshold is reached before the usage threshold, then the statistical information is offloaded to disc store 43 for further analysis. The data can also be offloaded at the end of day or when a volume is changed. When a large number of errors are encountered a data logging mode is entered. The statistical information can be analysed and printed out, e.g. for a maintenance engineer.  A control unit 5 may be a read only or read/ write microprogram unit using integrated circuits.
