Title: Improvements relating to the supply of dyestuffs, alum and other materials in solution or suspension, to paper pulp during its passage to paper making machines
IPC: D21H23/18
Filed: 1936-06-16
Abstract: <PICT:0475972/IV/1> In the manufacture of paper, necessary solutions or suspensions are added to the pulp stream immediately before its passage to the paper-making machine, from storage tanks through open nozzles, delivery of each solution or suspension being controlled by adjusting the hydrostatic head of the solution above its nozzle. Solutions or suspensions of rosin size, casein, sodium silicate, glycerine &c. dyestuffs, alum, glue, fillers are fed to pulp in its passage to a paper-making machine, from a tank 13, through a flexible hose 14, and float - valve ensuring constant level to a tank 5 counterbalanced by a weight 12 on a cable 7 wound up or down by a drum 10 and handle 11 or by a scale 15 attached at one end to the tank 5 and at the other to a spring-drum 16.  A pointer indicates on the scale the delivery rate or the hydrostatic head of liquid in the tank 5 above the delivery nozzle 1, different sizes of which nozzle may allow outflow rates in the ratio 1 : 10 : 100 &c. allowing the same scale to be used for each, as by the pointer covering columns of figures when requisite.  Two or more applicances may be mounted on a common frame, and deliver a mixture of substances.

Filed: 1974-04-18
Abstract: 1467899 Laminates ROHM & HAAS CO 18 April 1974 16980/74 Heading B5N A self-bonded laminate comprises (a) a transparent plastics surface film on (b) a crushed, crosslinked thermoset resilient plastics foam adhered to (c) a substrate, optionally with (d) a decorative layer between (a) and (b). The laminate may be produced by foaming a thermosettable plastics material without effecting thermosetting and applying it to the substrate, reducing the liquid content, if any, to a point where the foam can be crushed to a thickness of 5-25% of the thickness of the original foamed material without completely collapsing the foam, self-bonding a transparent plastics film to the foam, and before or after bonding the film thereto, crushing the foam to this thickness and curing it. The substrate (c) may be a woven, knitted or non-woven textile material of glass, nylon, polyester, cotton, wool, rayon or spandex yarns, paper, paperboard, plastics film, leather, leather substitute, wood or metal e.g. steel iron copper aluminium brass or zinc which may be primed with an epoxy resin or mixture thereof with an aminoplast.

Title: Improvement in manufacture of composites of plastic materials and fibres
IPC: C08J3/22
Filed: 1931-06-11
Abstract: A fibrous composition is uniformly coloured by dyeing the fibres to the same colour as the binding material which may itself be artificially coloured.  The fibres are preferably coloured to a deeper shade than the matrix.  Such treatment is particularly advantageous in the case of rubber shoe sole compositions as it obviates the gray or dusty appearance produced by the exposed fibres after the sole is somewhat worn.

Title: The production of carbon fibres
Inventor: JOHNSON WILLIAM
IPC: D01F9/16
Filed: 1964-04-24
Abstract: Carbon fibres which are prepared from organic polymer fibres by a process which includes submitting the fibres at some stage of the conversion to the combined effect of heat and tension (see Division C1) are used as reinforcing elements in composite materials.  In Example 3 the following constituents were compounded in a rubber mill:-a fluoroelastomer copolymer of vinylidene fluoride and hexafluoropropylene, MgO, dicinnamylidone hexamethylene diamine (curing agent) and the carbon fibres of the invention. In Example 4 a mixture of polyester resin, methyl ethyl ketone peroxide and a 6% solution of cobalt naphthenate in white spirit was poured over a bundle of carbon fibres and the resin cured and set at ambient temperature. In Example 5 the procedure of Example 4 was repeated with an epoxy resin and polyamide hardener.  In Example 6 the carbon fibres were impregnated with a resin comprising diphenyl oxide and paradichloroxylylene in a dichloroethane solution.  After evaporation of the dichloroethane the fibrous mass was shaped and heat-cured at 180 DEG  C. and 500 p.s.i. for 2 hours.ALSO:Carbon fibres are prepared from organic polymer fibres, the fibres having been submitted at some stage of the conversion to the combined effect of heat and tension.  The polyme fibres may be exposed to an oxidizing atmosphere at a temperature of 200-300 DEG  C. for sufficient time for substantially complete oxygen permeation of the fibres while under a tension such that there is little or no longitudinal shrinkage, and then carbonized by heating to about 1000 DEG  C. under non-oxidizing conditions, optionally while still under tension. Preferably the carbon fibres are then heated to 2000 DEG C. or more under non-oxidizing conditions. In the examples the starting material is multi-filament polyacrylonitrile yarn.  Carbon fibres may be made from polyacrylonitrile fibres without a preliminary oxidizing step by submitting the polyacrylonitrile fibres to the combined effect of heat and tension at a carbonizing temperature of about 1000 DEG  C. under non-oxidizing conditions, optionally followed by further heating to at least 2000 DEG  C.  The carbon fibres of the invention may have tensile strengths of from 120 x 103 to 260 x 103 p.s.i. and a Young's modulus of from 20 x 106 to 60 x 106 p.s.i.  The carbon fibres may be used as reinforcement in synthetic plastic materials (see Division C3).
