Title: Scanning systems employing electromagnetic wave energy
IPC: H04N5/30
Filed: 1973-06-29
Abstract: 1399980 Television G O OKIKIOLU [trading as OKIKIOLU SCIENTIFIC & INDUSTRIAL ORGANIZATION] 18 July 1973 [29 June 1973] 31129/73 Heading H4F In a television camera light from a cathoderay tube flying spot scanner is directed, via inclined semi-transparent mirrors or a perforated mask, to a photosensitive device receiving an optical image, whereby the device produces a signal having an instantaneous value determined by the intensity of the image at the point of the device addressed by the flying spot. The mask or mirrors direct light from the CRT to a single corresponding position on the photosensitive device (i.e. they replace a lens or aperture). The CRT may provide X-rays, U-V, I-R or visible rays. In a display device, an electrooptic or magneto-optic device is supplied with video signals to modulate infra-red or visible light from a CRT flying spot scanner. By using beam splitters a plurality of cameras or display devices may be associated for use in colour television. A camera and display device may be combined, having a common flying spot scanner and being selectively operable using electric switches or optical shutters. Alternatively the camera output can be fed to the display input. If, in addition, the camera is directed at the display, electrical oscillations are produced.

Patent GB-485198-A (GB)
Title: Improvements in the treatment of artificial yarns, fabrics, films and the like
IPC: D06M15/423
Filed: 1936-11-16
Abstract: Yarns, fabrics, films and the like of organic derivatives of cellulose are rendered crease-resisting by causing the material to absorb an intermediate resin condensation product from a dispersion thereof in a non-solvent therefor, which is converted into a water-insoluble synthetic resin in the material, preferably by heating.  The condensation product is preferably applied in aqueous dispersion containing an acid organic dispersing agent, which may also act as catalyst for the formation of the resin. Suitable resins include aldehyde-ketone and amide resins, particularly formaldehyde with urea, thiourea, guanidine, aniline and certain substitution products thereof, aromatic sulphonamides and phenols; polybasic acids with polyhydric alcohols.  Any suitable dispersing agent may be used, e.g. sulphonated oils and water-soluble soaps; the latter may be formed in situ in the intermediate condensation product.  Local effects may be produced by effecting the polymerization locally.  In an example, urea is dissolved in aqueous formaldehyde and turkey red oil added, the colloidal solution so formed is diluted and a cellulose acetate fabric immersed therein, mangled, dried and heated for 15-30 mins. at 120-160 DEG  C., washed and dried; instead of turkey red oil, sulpho-naphthalene sulphonic acid may be used; the urea and formaldehyde may be boiled together before addition of the turkey red oil until a precipitate forms on cooling.  Materials so treated also have an increased affinity for cotton dyes, retain mechanical effects such as crimping in yarns or embossing, and have an increased resistance to water.  The resistance to water may be further increased by coating the material with wax-like substances applied in solution, e.g. in chlorinated hydrocarbons. According to the Provisional Specification, acrylic and vinyl resins may be employed; or instead of the resins specified there may be used ester resins, rubber, guttapercha and balata.
