Title: Improvements in or relating to image reproduction
IPC: G03F1/00
Filed: 1965-02-25
Abstract: 1,087,770. Copying by scanning. D. J. KYTE. Feb. 2, 1966 [Feb. 25, 1965], No. 8428/65. Heading H4F. In a process for the production of screened photo-reproductions of an original two separate photographic exposures of photo-sensitive material, such as " Lith " film, are made, one with a screen and a constant light source, the other continuously without a screen by means of a scanned light beam, the brightness of which is varied during scanning under control of signals derived from like scanning of the original, the screened exposure being such that by itself it does not blacken the photo-sensitive material. The screened exposure may be made by evenly flood-lighting the photo-sensitive material through a ruled screen, Fig. 2 (not shown), or through a contact screen applied to the photo-sensitive material by vacuum. The time of exposure is adjusted so that those parts of the film subjected to the greatest light intensity are exposed by an amount approximately equal to the amount X, Fig. 3 (not shown), so that the developed film will show no blackening, i.e. the film is presensitized in a two-dimensional cyclic pattern. The pre-sensitized sheet may then be transferred to a rotating cylinder (2), Fig. 1 (not shown), and scanned helically by a glow tube (10), the intensity of which is controlled by the output of photo-electric cell (7) which is caused to scan the illuminated original transparency (4) on rotating drum (1), i.e. a continuous tone image is produced. The final developed image comprises a pattern of dots, the size and/or densities of which vary as a function of the tone values of the original being screened. For the whole range of screen dots the maximum continuous tone exposure must be of the order of X, Fig. 3 (not shown), the threshold value of the film exposure characteristic. The continuous tone image may be produced before the film is pre-sensitized. Transparency (4) may be a colour transparency.

Filed: 1968-02-22
Abstract: 1,156,433. Hose. EAU ET FEU S.A. 22 Feb., 1968, No. 8712/68. Heading F2P. A hose constituted by a woven, braided or knitted jacket having a thin impermeable lining and an external cover is manufactured by introducing into the jacket 1 a lining tube 2 of rubber or expandable plastics having a composite surface layer formed by an inner abrasionresistant sub-layer 3 and an outer flexible sub-layer 4, subjecting the assembly to internal air pressure and external heat to cause the outer sub-layer to exude outwardly, applying pressure to the exuded material to form sheaths around the yarns of the jacket, continuing application of internal pressure and heat to cause the inner sub-layer to exude through the outer sub-layer and jacket to form projecting spikes and applying pressure to spikes to form an abrasion resistant cover. The two sub-layers 3 and 4 may be of suitable compounded polymer blends of nitrile rubber and polyvinyl chloride. Alternatively, the inner sub-layer may be polyurethane or a blend of polyurethane and polyvinyl chloride, the outer sub-layer being plasticized polyvinylchloride, and the lining tube being a blend of nitrile rubber and polyvinyl chloride. As a further alternative, the inner sub-layer may be a polychloroprene containing a carbon black filler, the outer sublayer a polychloroprene flexible compound, and the inner lining tube polychloroprene. The lining tube may also be of nylon. In a particular example, specific additives are given, the lining tube is extruded, and the textile jacket is woven with nylon wefts and warps of " Terylene " (Registered Trade Mark). Two travelling air ovens are used for heating the hose and each trailing three peripherally-distributed rollers for rolling down the exuded material of the inner and outer sublayers. In a modification, the outer sub-layer is itself constituted by an inner portion and an outer portion which form outer and inner sheathings respectively on the jacket yarns.
Patent GB-1005783-A (GB)
Title: Improvements in the production of aryl esters of phosphorus oxy-acids
IPC: C07F9/12
Filed: 1962-03-07
Abstract: <FORM:1005783/C2/1> An aryl ester of a phosphorus oxy-acid is obtained by introducing a phenol and the chloride of a phosphorus oxy-acid into a zone in which they react at an elevated temperature under conditions permitting back mixing to occur freely until the reaction is at least 50% complete and transferring the resulting mixture, still containing a substantial proportion of unreacted materials, to a second zone in which the reaction is allowed to go to completion under conditions which do not favour back-mixing of the contents of this second zone.  The reaction is preferably at least 85% complete before the mixture is transferred to the second zone. Back mixing in the latter zone may be diminished through the use of, e.g., cut baffles, perforated baffles, or packing, e.g. Berl saddles. The reactants are preferably allowed to flow continuously from the first zone to the second zone and to progress through the second zone continuously in a downward direction.  In the continuous process it is advantageous to apply heat only to the initial reaction zone and in a preferred method of operation the temperature of the reaction mixture is maintained by the method disclosed in Specification 1,005,784 by separately preheating the phenol fed into the reaction zone to a temperature high enough to vaporize all or a significant part of the phenol.  In the reaction zone the vaporized phenol condenses liberating latent heat which maintains the temperature of the reactants. The phenol may be heated by passage through a steam or direct fired heater and when cresylic acid is used as the phenol preferably more than 50% of it is vaporized by heating at from 208 DEG  to 227 DEG  C. at atmospheric pressure.  A catalyst, e.g. magnesium chloride, stannic chloride or titanium tetrachloride is preferably included in the reaction mixture.  A suitable reactor (see Figure) for carrying out the process continuously comprises a cylindrical tower 10 separated into a lower zone 12 and an upper zone 13, the zones being connected by a conduit 14.  Partially vaporized phenol and the chloride of a phosphorus oxy-acid are fed to the lower zone at 16 and 17.  Hydrogen chloride passes up through liquid disengaging space 18 and mist eliminator 19 and out overhead at 20. Back mixing in zone 12, which is maintained full, is effected by the agitating effect of the HCl gas evolved and baffles 15 assist in reducing back-mixing in the zone 13.  The fully reacted product is withdrawn continuously at 22.  An example is given in which cresylic acid comprising a mixture of xylenols, cresols and C9 phenols and a small proportion of phenol and C10 phenols is reacted with phosphorus oxychloride to form tricresyl phosphate.  Specification 877,271 also is referred to.
