Patent GB-593700-A (GB)
Title: Cellular zein boards
IPC: C08J9/04
Filed: 1944-12-01
Abstract: Boards of zein having an interior of blown cellular structure and smooth outer faces sealing off the cellular interior may contain a resin or a fibre filler, or both.  The resins may be thermoplastic or thermosetting and are exemplified by: polyvinyl alcohol, a maleic anhydrideglycerol-abietic acid resin or a substituted formaldehyde-glycerol-phenol resin in solid form, a copolymer of vinyl chloride and vinyl acetate, polyvinyl chloride, polystyrene, a ureaformaldehyde resin, a mixture of alkyd resin and a polymerized olefine such as styrene, a melamine - formaldehyde resin, a polyvinyl alcohol-butyraldehyde resin, nylon, cellulose acetate, ethyl cellulose.  The fibre fillers are exemplified by flock, cotton, wool, rayon, hair, mineral fibres. Other compounding ingredients, e.g. carbon black, whiting, gum arabic, stearic acid, may be incorporated. In making the boards, a zein-containing mass, containing a small amount of water or a chemical blowing agent, e.g. sodium bicarbonate and containing, if desired, a solvent for zein, e.g. methyl or octyl alcohol, or ethylene glycol, is subjected in a closed mould to pressure and to heat sufficient to vaporize the water or liberate gas from the blowing agent, and to cause the outside of the mass to flux and thereby trap the vapour or gas within the mass, and the pressure is then reduced to allow the trapped vapour or gas to expand the mass to a cellular structure.ALSO:Boards of zein, containing if desired a resin or a fibre filler or both, have an interior of blown cellular structure and smooth outer faces sealing off the cellular interior.

Title: Improvements in wire tensioners
IPC: F16G11/12
Filed: 1950-10-03
Abstract: 691,326. Wire strainers. STOREY, A. G. G. Oct. 1. 1951 [Oct. 3. 1950], No. 24101/50. Class 45 A wire tensioner comprises a link on which, intermediate its ends, a reel or roller is mounted for coiling the wire thereon to tension the same, the link having an eye on one end which is adapted to thread over a post, whilst the other end is engaged by the wire to be tensioned so that. the eyethreaded on the post is tilted to give a frictional grip on the post and thereby fix the eye in an adjusted position on the post. The link is made from a length of wire which is bent to form an eye 3 from which two arms 1 and 2 extend, the arms ending in eyes 4 which are superposed on one another and which engage the fence post. The arms 1 and 2 are each coiled in the centre to form bearings 5 for a tubular reel spindle 6 carrying flanges 7. The spindle 6 has an aperture for the wire to be strained and another aperture for a tommy bar 8 by which it is rotated. The tommy bar has a hooked end 10 which can be axially rotated into engagement with the link to prevent the reel unwinding. The wire passes through the eye 3 and its pressure tilts the eyes 4 on the fence post to hold the link against movement longitudinal of the post.

Title: Method of reducing the agglomeration and sticking tendency of a slurry
IPC: B01J2/30
Filed: 1966-05-31
Abstract: The agglomeration and sticking tendencies of slurries of particulate solids are reduced by adding a conductivity increasing agent to the slurry liquid.  The process is applicable to slurries of catalytic or absorptive solids in aliphatic or aromatic hydrocarbons, such as occur in processes for separating aromatics from paraffins, or normalfrom iso-paraffins, and in isomerization and cracking processes. Many suitable conductivity increasing agents are specified and the process is exemplified in relation to the removal of benzene from hexane by contact with silica gel in a rotating disc contactor, the agent being a mixture of calcium didecyl sulphosuccinate with the chromium salt of mono- and di-alkyl salicylic acids.

Title: Improvements in or relating to the manufacture of shotgun cartridge wads
IPC: F42B7/08
Filed: 1938-08-22
Abstract: 518,319. Moulding cartridge wads. DU PONT DE NEMOURS & CO., E. I. Aug. 22, 1938, No. 24694. Convention date, Aug. 25, 1937. [Class 87 (ii)] [Also in Groups XXI and IV] A shot gun cartridge wad comprises a bonded fibrous mass of wad-forming materials, with or without granular fillers, the said mass having been prepared from a dilute slurry of the wadforming materials containing a bonding agent in the form of separate non-adhesive particles by laying a shaped mass of the wad-forming materials from the said slurry and subsequently subjecting the said mass to treatment for the purpose of rendering the bonding agent adhesive. According to one embodiment, a slurry of a concentration of about 5 per cent. is prepared from unbleached sulphite pulp and mechanical pulp and beaten. To this slurry are added ground cattle hair, wood flour' and a bonding agent such as tapioca starch. The slurry is again beaten to secure uniform dispersion and distribution but not hydration of the solid materials. The prepared slurry is then dropped into a tank associated with the moulding or forming apparatus, diluted to a concentration of about 1 per cent. and constantly agitated during delivery to the moulding or forming apparatus which may be of the form described in U.S.A. Specification 2,026,765. The wads leaving this apparatus are treated with moist steam to effect colloidal dispersion of the starch and then dried. Instead of forming individual wads, a sheet from which individual wads may be cut can be formed from the slurry. If desired, a quantity of alum may be introduced into the mixture at the proper stages in manufacture in order to increase the adhesiveness of the starch, whilst, when it is desired to lower the gelatinization temperature of the starch, a thiocyanate or other salt may be added. As alternatives to the use of starch as a bonding agent, there may be employed materials such as casein, the salts formed by the reaction of casein and alkalis, cellulose glycollic acid or a salt of this acid, which are subsequently treated with an alkaline substance so that they are colloidally dispersed. Specifications 17141/89, [Class 87], 286,238, [Class 70], and 359,950, also are referred to.

[Class 55 (ii).] Heavy oil is atomized directly into an unobstructed zone 1 by means of an amount of preheated air insufficient for supporting complete combustion so as to obtain a free jet of hot products in which a partial combustion is being performed, the products then being transferred to a second zone separated from the first by a heat-radiating body 7 to the centre of which heat is imparted by substantially the whole of the products before leaving the second zone. The plate 7 rests upon two small partitions 8 between which the outlet 9 is located so that gases resulting from the more intense reactions at the periphery of the jet and passing through perforations 11a in the plate are caused to yield heat to the central part of the plate before mixing with the more central gases and escaping from the zone into the annular space 10 of an air preheater in which they are suddenly cooled. Additional partitions may be provided further to lengthen the gas travel under the plate. A modified plate has radial slots at the periphery with a few central orifices. Another heat-radiating body comprises a disc deflector with a slot at the periphery and a metallic spiral thereunder providing a spiral conduit leading from the slot to a central outlet. The disc may be perforated to allow products still containing free oxygen to pass through it.
