Title: Filament finishing
Filed: 1974-10-28
Abstract: 1492052 Textile lubricants PVO INTERNATIONAL Inc 28 Oct 1974 22449/77 Divided out of 1492051 Heading C5F [Also in Divisions D1-D2] Synthetic linear organic polymer filaments and fibres are treated with or incorporate a hydroxypivalyl hydroxy pivalate diester having the general formula in which R 1  and R 2  each represent an alkanoic or alkenoic monocarboxylic acid having from 2 to 24 carbon atoms. The coefficient of friction between the filaments and metal is reduced whilst a slight degree of filament-filament cohesion, so called "balanced cohesion" is produced and thus facilitates the handling of multifilament yarn. The diester is stable at high temperatures. The diester may be applied as an aqueous emulsion as described in parent Specification 1,492,051 as a neat liquid or in solution in an organic solvent. Filaments may be treated in a continuous process, staple fibres are treated in a batch process. The diester may be added to a polymer melt before it is spun into filaments. The diester may be formed from 2 moles of an acid selected from oleic, stearic, palmitic, lauric, nonanoic, iso-nonanoic, heptanoic or caparic acid or the other acids listed in Example VII or it may be formed from mixed acids, e.g. stearic/ iso-nonanoic or palmitic/lauric acids.

Filed: 1971-04-19
Abstract: 1307025 Valves KELSEY-HAYES CO 19 April 1971 [23 March 1970] 23316/71 Heading F2V Flow between an inlet 18 and an outlet 20 is controlled by means of a tiltable valve member 58 which is biased on to a seat 38 and which has an integral stem 16 extending therefrom, the stem being releasably coupled (Fig. 2, not shown), to posts 74 extending one from each of two diaphragms 84. The portion of the stem proximate to the coupling has a reduced section 91 which facilitates bending of the stem 16. The diaphragms are deflectable, e.g. to the position shown in broken lines, by actuators 90 with such deflection giving rise to a corresponding deflection of stem 16 and hence to a corresponding tilting of valve member 58 relative to its seat 38. Tilting of the valve member about the axis of valve seat 38 is ensured by forming the stem 16 with spaced radial projections 68 which engage the walls of the flow passage 40. A modified arrangement of projections is depicted in Figs. 4 and 5 (not shown). Four such valves may be employed (Fig. 6, not shown), to control the operation of a doubleacting piston and cylinder. In this case, the actuators 90 are dispensed with and the diaphragms 84 are selectively subjected to an actuating fluid pressure derived from the same source as is connectible, via the valves, to the piston and cylinder.

Abstract: 1,239,990. Cis - propenyl phosphonic acid diesters and derivatives thereof. MERCK & CO. Inc. 12 May, 1969 [15 May, 19681, No. 23967/69. Heading C2C. Diester derivatives of cis - propenyl phosphonic acid are obtained by treating a diester of ethynyl phosphonic acid with tetramethyl diborane, generally in an inert solvent, to yield a trans diester of 2 - (dimethyl boryl) vinyl phosphonic acid and treating the latter with iodine in the presence of a base e.g. an alkali metal- or alkaline earth metal hydroxide, preferably in an inert solvent. The reaction is generally conducted at below 40 C., preferably - 10 to 0 C. The diester product may be hydrolysed to the free cis - propenyl phosphonic acid e.g. by treatment with a mineral acid in the presence of a buffer, or by treatment with trimethylchlorosilane or toluene sulphonic acid and the phosphonic acid may then be epoxidized to ()(cis - 1,2 - epoxypropyl)phosphonic acid, e.g. by treatment with H 2 O 2  in the presence of an alkali metal pertungstate. The racemic mixture of ()(cis - 1,2 - epoxypropyl)phosphonic acid thus obtained can be resolved into its optically active components by the crystallization of salts of the acid prepared by reacting the acid with an optically active base, e.g. quinine, d - α - phenethylamine, strychnine or quinidine and the resulting salts, after isolation, can be treated with a base, e.g. NaOH, NH 4 OH or CaC0 3  to form the corresponding salt e.g. of (-)(cis - 1,2 - epoxypropyl)phosphonic acid from which the free acid may be obtained e.g. by passage through an ion exchange resin at 0-5 C. on the hydrogen cycle. The () and (-) (cis - 1,2- epoxypropyl)phosphonic acid and salts thereof have antimicrobial properties. The ester derivatives of ethynylphosphonic acid may be prepared by treating 3-pyranyloxy- 3 - methyl - 1 - bromo - 1 - butyne with a diester derivative of sodium phosphite to yield the diester derivative of 3 - hydroxy - 3 - methyl - 1 - butynyl phosphonate and then treating the latter with caesium carbonate at elevated temperature and under reduced pressure. The sodium diester phosphite may be prepared by treating a phosphite diester with sodium hydride.
