Title: Improvements in and relating to Linoleum and Linoleum Cement.
IPC: D06N1/00
Filed: 1918-01-28
Abstract: 123,791. Craven, A. B., and Yorkshire Dyeware & Chemical Co. Jan. 28,1918. Fatty acids, fatty oils, oxidizing. A linoleum cement is obtained by a process which primarily consists in oxidizing the fatty acids from drying and semi-drying oils, or the oils themselves (except tung oil, linseed oil, and soya oil), or the byproducts obtained in refining these oils, by means of gaseous oxygen or ozone until the requisite resilient, tacky, and adhesive product is obtained. The by-products employed are those resulting from the refining of oils by means of acid, alkali, or bichromate and acid, or by sedimentation, or the oily bodies recovered from fuller's earth. Mixtures of the raw materials may be used, the solidity of the product being adjusted by a suitable selection. Non-drying matters are removed from the raw materials when necessary by cold filtration or by distillation by the process described in Specification 121,777 which also effects a partial polymerization. A non-fluid product is also ensured by the addition of aluminium hydrate at a suitable stage, or by mixing resin or a gum resin with the products obtained by oxidation. The oxidation is conducted at 110‹ C. or more, and preferably in the presence of resinate, linoleate, hydrate, or other compound of lead, manganese, or cobalt, the operation normally taking from 14-25 hours. The treatment of linseed oil fatty acids, cottonseed oil foots, and a mixture of linseed oil fatty acids with cod oil are described. The raw materials may be preliminarily purified in the manner described in Specification 121,777.

Abstract: 1,267,764. Laminated non-woven fabrics. CHEMISCHE INDUSTRIE KEMPEN G.m.b.H. 14 Jan., 1970 [15 Jan., 1969], No. 1903/70. Heading B5N. [Also in Division D1] A patterned non-woven fabric is made by laying a pattern bonded needled non-woven web of a first colour on a needled non-woven web of different single or blended colour and needling the two webs together so that the fibres in the unbonded parts are needle punched through to the reverse side of the underlying fabric and the fibres in the bonded parts are only partially needle felted and do not pass through to the surface. The binder may be a gluten glue, vegetable glue or polyvinyl alcohol. The glue may be redissolved after needling the webs together so as to spread it throughout the web. A further binder, e.g. foamed acrylate resin and urea formaldehyde resin, can be applied to the completed web. Further webs may be laid on the first two prior to needling to obtain different colour patterns. The fibre length and thickness in the webs may differ. The webs may be made of red and black polypropylene fibres.
Patent GB-685063-A (GB)
Title: Improvements in or relating to stripping oil used in the coating of steel objects
IPC: C23C2/30
Filed: 1950-01-26
Abstract: A stripping medium for hot-dip metal coating comprises a mixture of a fatty oil, which may be hydrogenated, and an ester of a monohydric aliphatic alcohol with a fatty acid, the alcohol and fatty acid residues each containing 12 to 22 carbon atoms in the molecule.  The proportion of ester is from 10 to 35 parts per 100 parts of mixture. Examples of suitable esters are cetyl palmitate, stearate, and myristate; stearyl stearate and palmitate; myristyl stearate and palmitate; spermaceti; and the higher monohydric alcohol esters of jojoba oil.  A commercially available form of such esters is hydrogenated sperm oil.  Examples of suitable fatty oils, which should be nearly or completely saturated and have an iodine number below 30 for machine dipping and below 60 for hand dipping, are hydrogenated fish oils such as menhaden, sardine, pilchard, cod, herring or whale oils, hydrogenated vegetable oils such as soya, cotton-seed, peanut and rape oils, and hydrogenated animal oils such as tallow, lard or lard oil.  In some cases the sheets or other articles coated by the hot dip method are allowed to cool before passage through the stripping oil, which in that case is heated separately to about 450 DEG  to 550 DEG F. so that the heated oil reheats the coating during the stripping process.  The oil may also be used in this way for brightening plated articles which have been coated electrolytically.  The same oil may be used for making terne plate, for example with a molten mixture of 85 parts lead to 15 of tin.

The molar ratio of acetic acid to amine may be from 0.1:1 to 0.6:1, and the weight ratio of emulsifying agent to fatty amine may be from 0.01:1 to 1:1. A preferred emulsion contains 5% to 10% amine, 0.2% to 1% acetic acid, 0.5% to 1% emulsifying agent. The amine may be hydrogenated tallow amine (exemplified) or octadecylamine. The water-soluble polymer may be polymethacrylic acid, polyethacrylic acid, copolymers and terpolymers of acrylic acid, methacrylic acid and ethacrylic acid with each other and with other vinyl monomers, or salts of these. The non-anionic emulsifying agents include block polymers of ethylene oxide and propylene oxide on a propylene glycol or alkylene diamine backbone, polyoxyethylene fatty amines, polyoxyethylene N-fatty trimethylene diamines, alkyl chloride quaternary salts of polyoxyethylene fatty amines or of polyoxethylene N-fatty trimethylene diamines, ethylene oxide-propylene oxide random copolymers.

To provide a soft running-in surface on a wear-resistant spinning &c. ring, the ring has, at least on the surfaces on which the traveller slides, a layer at most 50Á deep of soft steel having a hardness of less than 60 on the Rockwell scale C which is intimately integrated with the 'base material of harder steel beneath it. The base material may be surfacehardened, or be hardened throughout; the softer surface may be steel of lower carbon content than the base material and be formed by deposition, spraying, annealing the surface of base material or by removing carbon from the base material. When the surface is formed by removing carbon from the base material, the ring may be subjected to a hardening- treatment which will then only affect the base. The ring may be coated with corrosion-resisting material.
