Patent GB-2459948-A (GB)
Title: A dry filler comprising glass beads coated with a microbiocide
Inventor: SHORT GODFREY STEWART
IPC: C04B14/22
Filed: 2009-04-24
Abstract: A filler (for use in a binder-and-filler material) comprises glass beads which are coated with a microbiocide (e.g. zinc pyrithione), the filler being dry. The microbiocide may be antibacterial, antiviral and/or antifungal. The glass beads may have a lower absorption of the microbiocide than most other materials that are conventionally used for this purpose. The glass beads may be substantially impervious to microbes so that the required amount of the microbiocide is reduced, for example from about 2 or 3% by volume to about 1% by volume. The glass beads are preferably made from pulverised fly ash having advantages of low cost, low density, high wear resistance, easy dispersion and homogeneousness. The microbiocide may disperse with the readily-dispersible beads when the beads are combined with the binder. The coated beads may be used as a replacement for a conventional dry filler when combining with the binder. The binder may comprise a plastics resin, Portland cement, gypsum powder, paint or lacquer.

Patent GB-166337-A (GB)
Title: Improvements in or relating to the printing of cotton fabrics
IPC: D06P3/64
Filed: 1920-04-12
Abstract: Cotton fabrics are mordanted by known methods in such a manner that one or more metallic mordants are fixed on some parts of the fabric, the tannate or tannates of these mordants on other parts, while yet other parts may remain unmordanted; they are then dyed with at least either one dyestuff having affinity for a metallic mordant only together with one having affinity for the tannate only, or, one dyestuff having affinity for both metallic and metal tannate mordants but in different degrees.  For example, a chrome mordanted fabric may be printed with tannic acid, steamed and washed, and dyed first with a dyestuff having affinity for the tannate only, such as methylene blue, and then with a dyestuff such as Chromorhodine B having affinity for the untanned mordant only; by using a single dyestuff, such as Prune pure, having affinity for both mordants, tone-in-tone effects may be obtained. The mordanting may be effected in any convenient way and may involve dyeing, padding, printing, or the use of discharge and resist colours; colouring-matters may be applied simultaneously with the tannin or metallic mordant; the fabric may also be first prepared with b -naphthol and a suitable diazo compound added to one of the printing colours subsequently applied.

Title: Sensitizable coated sheet adapted for electrophotographic reproduction
IPC: G03G13/28
Filed: 1959-03-25
Abstract: 912,836. Electrophotolithographic printing plates. PLASTIC COATING CORPORATION. March 25, 1959 [April 10, 1958], No. 10274/59. Drawings to Specification. Class 98 (2). [Also in Group XXXVI] A lithographic printing plate is made from an electrophotographic plate of form suitable for attachment to the printing cylinder of a lithographic press by charging and exposing the plate in the normal way, developing the latent image using an hydrophobic oleophylic toner such as resin or wax, and rendering the untoned areas hydrophylic by treatment in acidified ferrocyanide solution. The electrophotographic plate consists of a flexible base sheet one surface of which is coated with a dispersion of finely divided inorganic photoconductive material in a styrenated alkyd copolymer resin. In one embodiment a synthetic resin base sheet is used consisting of any of the polymeric materials listed in the Specification, but preferably of polyethylene terephthalate. The sheet is provided with a conductive coating by vacuum metallizing or cathode sputtering with a metal such as aluminium. To improve the adherence of the metal the sheet may be precoated with a film of resin, e.g. the copolyester of ethylene terephthalate and ethylene sebacate. Alternatively a conductive coating consisting of conductive solids dispersed in a film forming lacquer is applied. Suitable conductive solids are graphite, carbon black, copper, bronze, zinc, litharge, stannic oxide, and copper or silver sulphite but aluminium is preferred. 0.25-1.5 parts by weight of aluminium being used per part of film forming lacquer. Lacquers comprising cellulose acetobutyrate, ethyl cellulose, polyvinyl butyral vinylidene chloride-vinyl chloride copolymers, vinylidene chloride-acrylonitrile copolymers, vinyl chloride-vinyl acetate copolymers, and copolyesters of ethylene terephthalate and ethylene sebacate are suitable. As a further alternative a non-conductive clear lacquer coating is used. In another embodiment the base sheet consists of paper coated with a layer of casein-latex-clay mixture, or a cellulose derivative. A conductive or clear lacquer is applied as in the previous embodiment. In all the above cases the photoconductive material, preferably zinc oxide or lead oxide is applied to the base sheet dispersed in a solution of a styrenated alkyd copolymer resin in an organic solvent. Where zinc oxide is the photoconductor 2.6-4.5 parts by weight are used per part of resin. Specifications 907,909, 912,834, 912,835 and 912,837 are referred to.

Title: Improvements in or relating to radio navigation equipment
IPC: G01S1/30
Filed: 1964-03-12
Abstract: 1,055,805. Radio navigation. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 12, 1964 [March 15, 1963], No. 10405/64. Heading H4D. In a radio navigation receiver carried by an aircraft, the input carrier phase being compared in a detector 1 relative to the phase of a local signal from an oscillator 3 and the detector output voltage being utilized to control the frequency of the oscillator, the bandwidth of a low-pass filter 4 can be made very small by adding to the output of the filter a voltage corresponding to the velocity of the aircraft in the direction of the radio station. The outputs of speedometer 6, gyro compass 8- correponding to pitch and heading-and aircraft position are fed to a unit 7 which affords an output voltage corresponding to the horizontal velocity component parallel to the line connecting the aircraft and the radio station. Position-line determination is effected by comparing the phase of the output voltage from oscillator 3 with that from an oscillator similarly phase-locked to the wave from another radio station or with that of a reference oscillator.

Title: Improvements in and relating to colour photography
IPC: G03C7/18
Filed: 1941-07-25
Abstract: 553,229. Colour photography. KODAK, Ltd., and BRANCH, L. E. T. July 25, 1941, Nos. 10433/42 and 10434/42, [both divided out of 553,196Drawings to Specification. [Class 98 (ii)] In the subtractive reproduction of a multicoloured original by a photographic or photomechanical process, colour correction is effected by making three colour-component records from the original, by contact or projection printing on one support or on separate supports, while it is in register with a mask having a single image which, in order to compensate for the undesired light absorption of blue light by the colour component records coloured minus green and minus red, is a record of the blue light absorption of the said two component records in the original or in the copy, and is coloured minus blue. The masking image is not formed in a sensitive layer in which a colour component picture record is made, although it may be formed, e.g. as described in Specification 547,519 in a layer integral with a layer or layers containing colour component picture records ; and it has an absorption gamma as measured by blue light which is not more than 50 per cent less or 50 per cent greater than the sum of the absorption gammas measured by the same light, of the said two component records. The correcting process may be extended by using in the reproduction a mask having two images, e.g. in superimposed layers on a single support, or in a mixed grain emulsion layer, one of which is as specified above, and the other of which, in order to compensate also for the undesired absorption of green light by one of the said component records coloured minus red, or of red light by one of the said component records coloured minus green, is either a red component record coloured minus green or a green component record coloured minus red, and has an absorption gamma as measured by light of the colour undesirably absorbed, and for which correction is being made, which is not more than 50 per cent less or 50 per cent greater than the absorption gamma, measured by the same light, of the component colour image which exhibits the undesired absorption. The correction process may, with appropriate raising of the gamma of the mask, be extended to correct for undesired absorptions of the dyestuffs used in both the copy and the original if this is a subtractively-coloured photograph. The masking images may be coloured by direct or indirect colour development, the developed silver being removed. The colour of the masking image may be adjusted to compensate for incorrectness of the gamma of one of the records, e.g. the effective absorption gamma of a record may be reduced by including in the mask a proportion of colouring matter of the same colour as the record, and in this case the mask may be made by colour development of a single emulsion using a mixture of colour couplers of the same kind as those used in producing the original or the copy. Specifications 427,518, 427,520, 458,665, 418,942, 493,952, 494,341, 512,608, 517,416. 537,864, and 551,614 also are referred to.
