Title: Process for the manufacture of non-blocking dispersible powders
IPC: C08F18/08
Filed: 1967-12-30
Abstract: A non-blocking dispersible powder of a vinyl acetate polymer or copolymer having a glass temperature of 30 C. or below (down to -25 C.) is prepared by polymerizing vinyl acetate and optionally one other monomer in an aqueous dispersion to a monomer conversion of 80-90%, adding a polyvinyl alcohol of viscosity of 3-13 cps and a saponification value of 60 to 255 completing the polymerization, forming a powder by atomization, drying and adding an inert substance to the powder after it leaves the drier. The alcohol is preferably added in such a quantity that the powder contains 0.5- 4% of the alcohol. An anti-foaming agent may be added to the polymerization batch. In the examples, a vinyl acetate polymer, a copolymer of vinyl acetate and vinyl laurate, a copolymer of vinyl acetate and dibutyl maleate, or a copolymer of vinylacetate, vinyl chloride and vinyl laurate, are polymerized using hydrogen peroxide optionally with potassium persulphate and in the presence of polyvinyl alcohol as an emulsifier, and polyvinyl alcohol of viscosity in the range 3-13 cps is added, polymerization completed and the polymer dispersion atomized. Inert substances such as aluminium silicate kieselguhr or talc, and anti-foaming agents such as gluconic acid, a silicone emulsion or tributyl phosphate are added.

Title: Dedenting containers and the like
IPC: G09F5/02
Filed: 1969-06-19
Abstract: A method of reducing asymmetrical stresses in a cylindrical sheet metal container and restoring its shape by removing any dents comprises expanding the container by radially expanding and retracting inner dies past the yield point of the metal and compressing or shrinking the container by radially movable outer dies while supporting the container interiorly by said inner dies until the yield point is exceeded and the diameter of the cylinder is less than its original diameter and then collapsing the dies to allow the container to return to its original diameter. Apparatus for carrying out the method comprises a base 1, a head 2 and a casing 3 the base and head being connected by tension rods 4. An hydraulic cylinder 7 carried by tension rods 6 operates a conical member 9 which actuates spring-loaded segmental inner dies 10.

Title: Process for sulfolane bonding of textile fibers
IPC: D04H1/548
Filed: 1970-07-07
Abstract: Sulpholane (tetramethylene sulphone), unsubstituted or carrying up to 8 carbon atoms, blended with an organic diluent is applied to fibrous materials as a latent solvent, so that on heating the fibres bond to each other by being partly dissolved in the sulpholane. At least 25% of the fibres comprise one or more of polyacrylonitrile (85-100% acrylonitrile). Modacrylic (35-285% acrylonitrile), chlorofibres (vinyl or vinylidene chloride or copolymers thereof) or cellulose esters, cellulose diacetate, triacetate or acetobutyrate, vinyl acetate, vinylidene chloride, vinyl chloride, methyl acrylate, methyl methacrylate, vinyl pynidine or styrene may be copolymerised with acrylonitrile or the chloro monomers. The remaining fibres, if any, of the blend may be wool or other natural or synthetic fibres. The diluent is diethylene or triethylene glycol, dibutylphthalate, triethanolamine, 3-octyl sulphonyl ether. Trichloropropyl phosphate or alcohol or glycerol alkoxylates, the evaporation rate of the diluent being 0.01 to 3.5 times that of the sulpholane at 100 C. The blend may contain water. Carded or air-laid webs of staple fibres are cross-laid to form batts. The bonding blend may be sprayed, dripped or padded onto the fibres, the web or the batt. Compressed air may be used to force the blend through the batt, which may be treated from both sides. Heat is then applied. The batt may be needled or stitched before or after treatment with the bonding blend. Non-woven fabrics and blankets, knitted or tuffed articles and other woven frabrics may be surface bonded by spraying or padding with the blend to reduce piling.

Title: Phosphates
IPC: C09K21/02
Filed: 1970-11-27
Abstract: Complex phosphates of aluminum containing a halogen and chemically-bound molecule of a hydroxy compound, which may be water or an organic hydroxy compound. A typical example is a complex phosphate containing ethyl alcohol having the empirical formula AlPClH25C8O8.

Title: Oligomeric amino-containing aminolysis products of polymethacrylates or polyacrylates, and epoxy resin coating compositions containing such aminolysis products as curing agents
IPC: C08L63/00
Filed: 1978-01-10
Abstract: Novel, versatile aminolysis products are obtained by aminolyzing, with a polyamine of aliphatic nature, an oligomeric homopolymer of an alkyl methacrylate in which the alkyl group contains from 1 to 6 carbon atoms or an oligomeric copolymer of at least two alkyl methacrylates, such oligomers being produced from monomeric alkyl methacrylates by anionic polymerization to provide number average molecular weights in the range of 600 to 10,000 and preferably in the range of 1,000 to 5,000. Alternatively, an anionically polymerized homo-oligomer of a (C1-C6)-alkyl acrylate or co-oligomer of at least two alkyl acrylates in which the alkyl in at least one monomer has from 1 to 6 carbon atoms in the co-oligomer, and the alkyl in the comonomers may have from 1 to 18 or more carbon atoms, are aminolyzed with a polyamine of aliphatic nature. Instead of oligomers obtained by anionic polymerization of esters of acrylic acid or of esters of methacrylic acid, there may be used in the aminolysis, oligomers of corresponding low molecular weight obtained by free radical polymerization, and in this version there may also be included copolymers (not obtainable by anionic polymerization) of an ester of methacrylic acid with an ester of acrylic acid and also copolymers of one or more such esters with monomers not of ester type, such as styrene. The aminolysis products have outstanding utility in the coatings field, particularly as the hardener for curing epoxy resins.

Title: Yarn piecing device for open-end spinning machines
IPC: D01H4/48
Filed: 1978-09-13
Abstract: The invention relates to apparatus for piecing-up yarn on an open-end spinning machine. A yarn reserve forming member is movable between an extended position, in which it constrains the yarn to follow a prescribed reserve yarn path, and a retracted position, in which the yarn follows another prescribed and shortened path and the end of yarn and its length, which is the difference between the lengths of said prescribed paths, is permitted to return to the spinning means to contact fibres fed thereto. To achieve efficient piecing-up, the yarn moves between such prescribed pathways from one to the other under control of the reserve forming member while the reserve yarn path is in a sense depleted and the yarn is caused by yarn insertion means to be inserted in the delivery roller nip at a predetermined position in the course of movement by the reserve forming member when the latter moves to the retracted position. Preferably, the yarn is engaged by a yarn retaining means when in the extended position from which it is released by the resultant tension in the yarn at the end of the movement of the reserve forming member to the retracted position.

Title: Telecommunications line current supply circuit - uses two differential transistor amplifiers, first as master and second as follower
IPC: H04M19/00
Filed: 1978-09-29
Abstract: A telecommunication line supply circuit is designed for a telephone exchange terminal. The circuit has two continuous current generators one of which is the "Master" the other the "Follower". The 'Master' generator supplied a first conductor of the line, whilst the 'Follower' generator supplies a second conductor of the line. The 'Follower' has a control circuit which ensures line impedance matching. The 'Master' generator has also a control circuit which regulates the value of continuous current supplied to the line to is resistance value whatever the value of the resistance. The 'Master' generator control circuit is designed so that the current provided by the 'Master' generator is constant as long as the lines resistance is less than a step resistance value. The current is reduced in value as a function of the resistance value of the line when its value is greater than the step value.
