Filed: 1917-10-12
Abstract: 117,359. Jelley, J., and Jelley, H. Oct. 12, 1917. Drawings to Specification. Saddles.-In the manufacture of cycle and similar saddle tops from composite material of fabric and rubber by shaping blanks in pressure moulds or dies and simultaneously or subsequently applying heat for the purpose of vulcanizing the rubber, prior to being faced with rubber, the fabric is slit around the edges so that the skirt portions are rendered flexible and can readily conform to the shape of the moulds. The fabric may be rubberproofed canvas having sticky surfaces, so that, when the slit blank is given a preliminary shaping by hand, any overlapping parts can be made to adhere by finger pressure. The hand-shaping may be conducted in a mould having locating-pins, as described in Specification 115,305, and, to produce a reinforced top, such as described in Specification 1059/15, strips of proofed canvas can be affixed by hand-pressure to the blank, and strips are proferably applied to the slit-edge portions. After the preliminary shaping and strengthening of the fabric blank, an inner layer of rubber is applied thereto, the roughly shaped fabric and the rubber layer are removed from the die, another or top layer of rubber is placed in the die, and then the fabric and inner rubber layer are replaced over the top rubber layer; the built-up top is then ready for the pressure treatment between the pair of moulds. Specification 116,999 also is referred to.

IPC: B27N3/24
Filed: 1950-06-20
Abstract: Wallboard is manufactured from a continuously travelling preheated mat of discrete or comminuted cellulosic material mixed with a powdered thermosetting resin by subjecting the mat to compacting in a compression zone between endless metal bands to reduce the mat to the required gauge and density and then to a holding pressure to prevent recovery during the curing of the resin, the mat being reduced at a temperature of 90 DEG -100 DEG  C. and at a moisture content equal to the hygroscopic equilibrium of the cellulosic material at normal atmospheric temperatures, and the resin having a high or maximum fluidity at a temperature not substantially different from the compression temperature, and possessing a rate of cure relative to the effective length of the press and the rate of travel of the material, such that the completion of the cure is effected at the end of the holding pressure zone.  The cellulosic material may be wood sawdust, cork, bark, cotton, linen, flax straw, hemp, cane, bagasse and husks in powder, granular, chip, fibre or filament form.  For wood sawdust the moisture content should be 6-10 per cent and the compression pressure 200-500 lbs per square inch, and the holding pressure 50 lbs per square inch.  Preferably the mat is heated up to 70 DEG  C. by external heating in a saturated atmosphere, and is then radio frequency heated to about 95 DEG  C.  The resin may be a phenolic or amino plastic type and may be used in proportions of about 5 per cent.  The process may be carried out in a caterpillar type of press as described in Specifications 665,275 or 665,276.

Abstract: 646,755. Artificial pearls. POELMAN, A. J. J. June 9, 1948, No. 15569. Convention date, June 10, 1947. [Class 70] [Also in Group VII] The cores of imitation pearls and the like are coated by placing the cores on a surface where they receive the coating varnish except in the vicinity of their points of contact with that surface, and in varying these points of contact during the coating operation. When coating by means of an air brush the cores 1, Fig. 7, may be positioned on the holes of plate 4 which forms part of box 7 by means of a partial vacuum applied through pipe 8. After initial coating, a similar box is placed over the cores and the partial vacuum transferred to the new box, and the cores resprayed. In a modification, Fig. 6 (not shown), the cores may be positioned on adhesive tape and then re-positioned by applying an adhesive tape of greater adhesive power than the first. A continuous system, Fig. 8 (not shown), may be used in which the cores are laid out in trays, sprayed by an air brush, dried by infra-red radiations and then reversed and re-treated. When coating by dipping, the cores 1 may be enclosed in a chamber 12, Fig. 11, containing a gaseous atmosphere above a varnish bath 13. A piston 15 exerts pressure on the varnish but the gaseous layer prevents the varnish from completely covering the cores. In a further device for rotating the cores, Fig. 9 (not shown), the cores rest on a base plate fitted with holes which are sufficiently large for a part of the surface of the core to pass through and to be supported on a moving rubber band which causes the core to rotate slowly and continuously.

Abstract: Polymers of ethylene alone or with another monomer are made in the form of films, by polymerizing the monomer or monomers in the presence of a catalyst consisting of an organo-metallic compound of Group I, II, and III of the Periodic Table and a transition metal compound, on a liquid surface of a liquid reaction medium throughout which the catalyst is distributed, and which has no solvent effect on the polymer formed at the polymerization temperature.  The Specification contains an extensive list of monomers which may be copolymerized with ethylene.  The monomers may be selected from alpha mono-olefines, non-conjugated dienes such as dicyclopentadiene or 1, 4-hexadiene, 5-alkenyl-substituted-2-norbornenes, 5-methylene-2-norbornene, or 2-alkyl-2, 5-norbornadienes. The Specification also contains long lists of two and three component catalysts. Polymers exemplified are polyethylene and copolymers of ethylene and propylene, and terpolymers ethylene, propylene, and 1, 4-hexadiene. The exemplified catalyst is a mixture of vanadium tris (acetyl-acetonate) and diisobutyl aluminium monochloride which may be made by reacting triisobutyl-aluminium and aluminium chloride.  The liquid reaction medium may be methylene chloride, ethyl chloride, or 1,2-dichloroethylene.  The monomers and solvents may be purified before use.  The polymerization is effected in the absence of oxygen. The polymerization of ethylene and other gaseous monomers is effected by passing the monomers over the liquid surface.  When a liquid monomer is used as a comonomer it may be dissolved or dispersed in the liquid reaction medium.  The catalysts may be preformed or formed in situ. The polymer may be recovered as a coherent film, or scraped off by a doctor knife technique. Elastomeric polymers can be mill dried.  Specification 778,639 is referred to.
