Title: Recovery of synthetic resin scrap
IPC: B29C48/08
Filed: 1963-08-01
Abstract: 977,955. Reclamation of scrap synthetic resin. E. I. DU PONT DE NEMOURS & CO. Aug. 1, 1963 [Aug. 1, 1962], No. 30633/63. Heading B5A. In a process for the reclamation of thermoplastic synthetic resin scrap, particles of the scrap are compacted in a tapered screw compactor 4 and issue into a melt screw extruder 7 and are extruded as molten resin. The screw 3 of the compactor is driven by motor 1 through coupling 2 at a controlled torque so that compacted synthetic resin passes into the extruder at a constant pressure of from 75 p.s.i. to just below the pressure at which the compacted resin would be converted into melt. A cutter 10 cuts the extruded resin into pellets. By this process particles having relatively high bulk density are obtained from particles of low bulk density and can be used in extrusion processes for forming films &c. Non-thermoplastic material such as hemp or asbestos may be added to the thermoplastic resin before compaction. Two examples are described of the treatment of scrap polyethylene film.

Title: Improved antifogging and stabilizing agents for photographic silver halide emulsions
IPC: G03C1/29

Abstract: 742,221. Stabilizing photographic emulsions. KODAK, Ltd. Nov. 9,1953 [Nov. 8,1952], No. 31023/53. Class 98 (2). The tendency of a photographic silver halide emulsion to produce fog and lose speed on storage is reduced by the incorporation therein or in a colloid layer on one or both sides of the support or in a processing bath such as a developing bath or pre-bath of an organic compound of mercury in which the mercury atom is attached by a non-ionic bond to an organic nucleus and by an ionic bond to an anion. Mercury compounds specified include p-aminophenyl mercuric acetate, 3-chloromercuri-lchloromercuriphenyl - 4 - methoxy - 3 - methyl - 3 : 4 - dihydro - 5 - pyrazolone, 2: 5 - dichloromercurifuran, 2 - amino - 5 - chloromercurithiazole, and 2-acetoxymercurimethyl-5-methoxy - 2: 3 - dihydrobenzofuran. The mercury compound may be added to the emulsion in a solvent, e.g. water, a lower alcohol or a ketone, at any stage before coating, e.g. after final digestion. The emulsion may be dye-sensitized and may be chemically sensitized by digestion with naturally active gelatin or by addition of sulphur compounds, salts of ruthenium, rhodium, palladium iridium, or platinum (antifoggants in higher amounts), gold salts, stannous salts, polyamines such as diethylenetriamine and spermine, or bis-(#-aminoethyl)-sulphide and its water-soluble salts. In example 1, speed, gamma and fog data before and after incubation are given for an emulsion sensitized with potassium chloroaurate, a sulphur sensitizer, and a stannous salt, with and without 2-pyridyl mercuric chloride as anti-fogging agent. Similar data are given in example 2, using 3-chloromercuripyridine as antifogging agent, and in example 3, using an emulsion sensitized with a sulphur sensitizer and ammonium chloropalladate and using 2-pyridyl mercuric chloride as antifogging agent. Similar data are given in example 4 for an emulsion sensitized with allyl thiourea and potassium chloroaurate and for this emulsion also sensitized with triethylenetetramine, using as antifogging agents with this further sensitized emulsion 8-chloromercuriquinoline and 2-chloromercurithiophene. In example 5, similar data are given for the emulsion as in example 4 without triethylenetetramine, 8-chloromercuriquinoline being used as antifogging agent. In example 6, similar data are given for an emulsion sensitized with allyl thiourea with and without 2-chloromercurithiophene (in different quantities) and 8 - chloromercuriquinoline. Specifications 235,211, [Class 98 (ii)], 602,158, 602,160, 618,061., 636,140, 658,592, 661,645, 663,019, 664,230, 680,593, and 682,355 are referred to.

Abstract: 810,245. Heat treatment furnaces. WILSON, L. Oct. 11, 1956 [Oct. 24, 1955], No. 31042/56. Class 51 (2). In a bell furnace for heat treating coils of wire carried by the stem of a spider, the base of the spider rests on vanes forming open-topped passages extending radially from an opening in which a blower is arranged below an annular blower inlet plate which also rests on the vanes. Vanes 10 extend helically outwards from the space surrounding a blower 11, an annular inlet plate 13 resting on the inner ends of the vanes, which may be recessed so that the top surface of plate 13 is flush with the upper edges of the outer part of the vanes 10. Furnace atmosphere drawn in through the centre opening of plate 13 is directed outwardly between the vanes 10 to the outer part of the furnace. Coils of wire C are supported on three spiders comprising an apertured baseplate 15 and a tubular stem 18 which is ribbed or corrugated and has holes 19 to allow the atmosphere to reach the inside. The flow outwards between the vanes 10 induces a secondary atmosphere flow around the coils C through the apertured spider stem and base. In a modification, Fig. 5, a single spider is supported above spacing 'struts 26 and an inlet plate 24 by a grating of concentric rings 30 spaced apart by radial and diagonal webs. In this case the secondary flow passes through the coils and down outside the stem 15 of the spider.
