Patent GB-765294-A (GB)
Title: Method of producing hollow objects of a thermosetting resinous material
IPC: B29C33/50
Filed: 1955-01-04
Abstract: In making tubes or other hollow objects from thermosetting resins (e.g. thermosetting polyester resins, phenol-resorcinol resins or epoxy resins) the object, which may be reinforced with glass fibre or cloth, is formed around a hollow former which has been made from a thermoplastic material (e.g. polyvinyl-chloride, cellulose aceto-butyrate, polymethylmethacrylate) then exposed when above its softening point and cooled in this expanded condition.  The thermosetting resin is then cured and during or after curing it the former is heated to above its softening point, when it shrinks to its original size, and may be easily withdrawn. In an example, the former comprised a P.V.C. tube which was heated and blown up into contact with the inside of a metal tube and then cooled in this expanded condition.  A glass-fibre-reinforced polyester tube was formed around the former and cured, after which the former was shrunk by heating and removed.  In another example a bottle is made.

Title: Improvements in or relating to photographic silver halide emulsions and elements containing the same
IPC: G03C1/053
Filed: 1958-01-02
Abstract: 825,264. Photographic silver-halide emulsions. DU PONT DE NEMOURS & CO., E. I. Jan. 2, 1958 [Jan. 14, 1957], No. 199/58. Class 98(2) The emulsions have a water-permeable binding agent of 40 to 70% of a butadiene/acrylonitrile copolymer' containing 30 to 40% of the acrylonitrile component and the remainder of protein, usually gelatin. Preparation of the copolymers in aqueous medium is briefly described, and they may be mercaptan-modified in amount up to 1% of the copolymer; they are preferably added from aqueous dispersion to aqueous colloid-silver halide emulsions which are then coated by conventional methods. Additives, particularly sensitizers, of which numerous types are quoted, may be present in the emulsions. The coatings are usually of cine positive type and the advantage thereof is that focus flutter in projection caused by change of curvature in the film gate, from concave on the emulsion side facing the exposing light to convex, under the influence of radiant energy from such light is minimized. Backing, antiabrasive and additional emulsion layers when present may be prepared from the same binding agent. Example I describes coating of a polyethylene terephthalate film with vinylidene chloride and then gelatin sublayers before the layer of the invention, and then this and eight further examples continue with numerous comparisons of flutter and blister effects of such layers and ordinary gelatin emulsion layers, after exposure and processing, as affected by repeated projections. Specification 738,640 is referred to.

Abstract: 468,237. Telescope sights. TAYLOR, W., and KAPELLA, Ltd. Jan. 3, 1936, Nos. 249 /36 and 14 /37. [Class 119] A telescope sight is pivotally attached to a rifle on an axis substantially parallel to and in one plane with the axis of the sight and of the rifle respectively. As shown, the telescope A is provided with a pair of lugs B, C integral with the telescope or with a bar E secured to the telescope by screws D. The rifle R is similarly provided with a pair of lugs F, G integral with the rifle or with a bar I secured to the rifle by screws H. Holes J, K are bored through the lugs F, G parallel to the axis of the rifle ; the lugs B, C are fitted with pivots j, k parallel with the axis of the telescope ; and the pivots are inserted into the corresponding holes J, K from the rear. To ensure interchangeability irrespective of small variations in size, the holes are broached over 60‹ at one side k1, Fig. 2, and spring plungers N are provided to press the pivots against the edges of these broached parts. One at least of the pivots is made with a flat co-operating with the spring plunger to hold the sight in operative position, and if desired also with another flat P for holding the sight in the off position. The engagement of the plunger with these flats also prevents the withdrawal of the sight except when the sight is turned out of these extreme positions.

Abstract: 198,304. Lewis, J. Dec. 8, 1922. Food for animals.-Poultry and animal foods in granular or powdered forms are manufactured from household waste, condemned foods, &c. by a 'process in which some fatty moisture is extracted by centrifugal apparatus in conjunction with wet steam, the food being afterwards dried by air or superheated steam at a high temperature and low pressure. The material is sorted out on a sorting table and disintegrated and then passed into a centrifugal extractor into which wet steam is injected. From the extractor it is elevated to the drier, where it comes into contact with steam or air at a temperature of about 800‹ F. A low pressure is maintained in the drier and the cooled and sterilized material is discharged from it at a temperature of about 240‹ F. after having remained in it about 35 minutes. The material is thus cooled and afterwards screened to separate the granules, the remainder being crushed or ground. It is stored for a time before packing. A mixing-drum may be employed between the centrifugal extractor and the dnier.
