Filed: 1926-02-02
Abstract: 261,950. Armstrong Cork Co., (Assignees of Humphreys, C. F., and McCarthy J. C.). Dec. 11, 1925, [Convention date]. Inlaid linoleum.-In inlaid coloured linoleum certain of the coloured inlays are indented so as to bring the pattern into relief. The invention is particularly applicable to moulded inlaid linoleum having tile patterns, in which the parts representing the mortar joints are indented. The inlays 4 - - 8, Fig. 3, are applied to a backing 2, Fig. 4,. in the usual way, and the inlay portions 8 are then sunk or depressed to form shallow grooves 9 to imitate the joints. The grooves are relatively wide and shallow, being from 1/32 to 3/64 of an inch in depth, and preferably have rounded edges to facilitate cleaning. The linoleum is preferably formed by moulding, that is, the mixes which form the inlays are placed by stencils in granular condition on the backing and then compressed. The junction lines 'between the inlays in this type of linoleum are slightly irregular. Straight-line inlaid linoleum may also be used, the inlays being cut from sheets of calendered and dried mixture. After the linoleum is made it. is passed through an embossing plate which indents the desired parts of the pattern, and the material is then cured. The indenting operation mav be carried out on the cured linoleum, in which case it is previously heated. Alternatively, the indenting operation may be carried out simultaneously with the compressing of the linoleum in the ordinary process of manufacture.

Title: Improvements in processes for the treatment of textile fibres
IPC: D06B5/00
Filed: 1922-02-04
Abstract: Wool, either wet or at normal conditioning dryness, or other textile fibre in hanks or other forms are relatively tightly packed in wagons which are run into chambers.  Air is evacuated from the chamber till a pressure of 0.2 lbs. per sq. inch is reached and a pure bleaching gas, such as sulphur dioxide or chlorine, is passed into the chamber at ordinary temperature. After an hour the chambers are again evacuated and air is admitted till atmospheric pressure is attained. When chlorine is used its pressure is not allowed to rise above 4 lbs. per sq. inch, and if non-animal fibres are being bleached or animal fibres are being rendered unshrinkable the pressure of the chlorine is about 1/2 inch of mercury.  The chambers may be arranged in pairs so that fresh gas need not be used at each operation. According to one Provisional Specification, the evacuation lasts for 50 minutes and the gas is circulated by pumps for 2 hours.  According to the other Provisional Specification, the sulphur dioxide may reach a pressure of 70 lbs. per sq. inch.

Title: Polymerisation of fatty acids
IPC: C07C51/353
Filed: 1963-01-30
Abstract: Unsaturated fatty acids are polymerized by heating in the presence of a lithium stabilized clay in the absence of water. The lithium may be present as a compound in the clay or lithium ions may replace cations such as potassium sodium, calcium and magnesium in the clay. The clay may be present in 10 to 35% by weight based on the fatty acid, and a temperature in a range 160 to 230 DEG C. at atmospheric pressure is preferred. The product is filtered and decolourised by conventional methods. Acids with from 8 to 22 carbon atoms are listed and acetylenic acids may be used.  Examples describe the polymerization of tall oil fatty acids and oleic acid.ALSO:Lithium stabilized clays are used in the heat polymerization of unsaturated fatty acids in the absence of water.  Lithium compounds are incorporated with the clay, e.g. montmorillonite containing Fe impurities, and the lithium ions may replace at least in part the cations such as potassium, sodium, calcium and magnesium, of the clay.  The lithium compounds added to the clay may be lithium halides, e.g. LiCl or LiF, salts of aliphatic hydrocarbon monocarboxylic acids with up to 22 C atoms, or hydroxide or carbonate which form a fatty acid lithium salt in situ.  The exchangeable cations in the clay may be replaced by adding a soluble lithium salt followed by washing or dialysis purification, or by treating the clay with a cation exchange resin in hydrogen form, or a dilute solution of strong mineral acid followed by solutions of lithium compounds.  Examples describe the polymerization of tall oil fatty acids and oleic acids using lithium treated clay obtained by the several methods.
