Title: Improvements in or relating to circular knitting machines
IPC: D04B9/10
Filed: 1941-09-29
Abstract: 550,371. Knitting-machines. MELLOR, BROMLEY & CO., Ltd., BROMLEY, T. C., and SHORTLAND, A. Sept. 29, 1941, No. 12604. [Class 74 (ii)] The sinkers or web-holders of a circular machine and associated with inactive needles are moved inwards immediately after the outward movement so that yarn lying on the outside of the needles extends over the outer edges of the ribs or noses of the sinkers and is prevented from undesirable engagement with the sinker. The early timing of the sinkers is effected during both forward and reverse strokes of reciprocatory knitting. The invention is described in connection with a double-cylinder machine in which needles are rendered idle for fashioning purposes as e.g. in making heel and toe pouches. In one form, Fig. 10, an adjusted portion 6a is provided in the sinker cam ring so that the sinkers are moved inwards early as at position J so that yarn Y held by the last active needle 2 will lie over'the top edges of the sinkers 3 corresponding to the inactive needles. In a modification, Fig. 13 the sinkers corresponding to inactive needles are moved inwards by the engagement of lateral projections 23 upon the needle sliders 13, when the sliders are moved to heeling height. Alternatively, lateral projections may be provided upon the sinkers to engage sliders moved to heeling height.

Filed: 1926-07-14
Abstract: 278,982. Dicker, S. G. S., (Verein fiir Chemische Industrie Akt.-Ges.). July 14, 1926. Double compounds of santalol esters with hexamethylenetetramine are prepared by bringing the components together, preferably in the presence of a solvent such as chloroform, carbon tetrachloride, or benzene, at normal or elevated temperature. The products possess enhanced pharmaceutical properties. An example is given according to which santalol is treated with bromacetylbromide, and the resulting bromacetic and santalvl ester allowed to stand in chloroform solution with hexamethylenetetramine, when a crystalline powder separates out. Other santalyl esters mentioned are the halides, nitrate, sulphate, sulphocyanate. alkyl- or aryl-sulphonates. e.g. the benzenesulphonate; santalyl esters of halogen-fatty acids and arylsulpho-fatty acids are also referred to. Santalyl nitrate is obtained by treating santalol with a mixture of concentrated nitric acid and sulphuric acid. Santalyl sulphate is prepared by treating santalol with sulphuric acid. Santalyl sulphocyanate results when mixed solutions of santalyl chloride and sodium sulphocyanate in dry acetone are allowed to stand, the sodium chloride filtered off. and the acetone distilled. Santalyl benzenesulphonate is produced by cooling mixed solutions of santalol. benzene sulphochloride, and pyridine in ether, the resulting solution with water, drying, and distilling the ether away.

The hydrophilic phase may contain by weight 1 to 99% water, 99 to 1% of alcohol, e.g. methanol, isopropanol, butanol or isobutanol or up to 80% of an organic acid or acid-alcohol, e.g. formic, acetic, lactic or tartaric acid. When the hydrophilic phase comprises an alcohol the required acidity may be provided by mineral acid or a salt, e.g. ammonium tartrate or sulphate providing mineral or organic acid, or by the anionic dyestuff when used in the free acid form. The lipophilic phase is preferably a chlorinated aliphatic hydrocarbon having 1 to 3 carbon atoms, e.g. methylene chloride or trichlorethylene, white spirit or petroleum ether. The constituents of the composition may form an azeotropic mixture and swelling agents may be present.

Abstract: 1, 34,174. Filters for liquids. WALKER MANUFACTURING CO. April 3, 1963 [April 6, 1962], No. 13174/63. Heading B1D. A filter element comprises a porous body formed of substantially uniform diameter resincoated rayon fibres, said fibres being disposed randomly and being moulded under heat and pressure to a rigid shape, the resin acting as a binding agent. A filter cartridge 1 has a perforated outer shell 3, and a perforated inner shell 5 between which lies the filter medium 9 and a fabric sleeve 7. A cap 11 seals the top of the filter whereas annular cap 13 leaves shell 5 open. Oil flows from outside to inside, via filter 17 and filter 21 of the above-defined type. Filter 17 comprises a material such as waste cotton, whereas filter medium 21 is preferably composed of viscous rayon fibres of 60-70Á in diameter which are crimped and coated with a resin bonding agent, e.g. a phenolformaldehyde resin, and then moulded under pressure and temperature to form a rigid structure. The shape of element 21 is such that its inner surface area is equal to its outer surface area, and this is achieved by tapering the unit at top and bottom. The element itself is attached to the base of cap 11 so that the whole may be removed as a unit. In a further embodiment, uniform porosity of the element is obtained by forcing an air stream containing short fine fibres through the element. The fibres deposit themselves in regions of high flow and produce uniformity of porosity, themselves acting as a filter medium. The fibres may if desired be resin coated so as to stick and can be moulded into place. They may also be of rayon but may be selected and treated to absorb, adsorb and/ or strain out impurities
