Patent GB-857335-A (GB)
Title: Fluorocarbon acids and derivatives
IPC: C07C311/02
Filed: 1956-12-31
Abstract: The invention comprises perfluoroalkanesulphonamido alkylenemonocarboxylic acids of the general formula:  Rf SO2 N(R1)R-COOH where Rf is a perfluoroalkyl residue containing 4 to 12 carbon atoms, R is an alkylene bridging group containing 1 to 18 carbon atoms and R1 is hydrogen or an alkyl group containing 1 to 6 carbon atoms and the acid chloride, metal and ammonium salt ester and amide derivatives of the above acids.  The acids may be prepared from a perfluoroalkylsulphonyl fluoride RfSO2F which is converted to a sulphonamide and then to a sulphonamide salt by treatment with an amine and then an alkali, condensing the sulphonamide salt with an omega-halogenated carboxylic ester, hal-R-COOR1, and hydrolysing the resulting ester to give the desired acid.  The acid derivatives may be prepared by conventional methods. Articles coated with these compounds are stated to have both water and oil repellent surfaces. In Examples (1) N-ethyl-N-perfluorooctanesulphonyl glycine, C8F17-SO2(CH2H5)CH2 COOH, is prepared from perfluorooctanesulphonyl fluoride, ethylamine, and ethyl chloroacetate.  The preparation of the lithium, sodium, potassium, ammonium, aluminium and zirconium salts is described together with that of the acid chloride, 2-ethyl-butyl ester, ester of the monomethyl ether of diethylene glycol, acid amide, N-ethyl amide, N : N-dibutyl amide and N-alkyl amide.  The preparation is also described of an amidoalkylene dialkylamine compound by treating the acid chloride with beta-dimethylaminopropylamine and the resulting compound is quaternized by treatment with ethyl bromide to give a solid quaternary bromide.  (2) N-perfluorooctanesulphonyl glycine is prepared by oxidising N-alkyl-perfluoroctane-sulphonamide which is itself obtained by treating perfluoro-octane-sulphonyl fluoride with alkylamine, N-perfluoropentanesulphonyl glycine and N-perfluorodecanesulphonyl glycine may be similarly prepared. (3) N-perfluoroctanesulphonyl-beta-amino-propionic acid is prepared from perfluorooctanesulphonyl fluoride and beta-propiolactone.  (4) and (5) N-methyl perfluoro-octanesulphonamide is condensed with ethyl-omega-bromoundecylate to give, on hydrolysis, an acid C8F17 SO2N(CH3(CH2)10-COOH, a similar compound may be prepared using ethyl-omega-bromostearateor, N-ethyl perfluoro-octanesulphanamide. Specifications 758,467, 857,334 and 857,336 are referred to.

Abstract: 1,242,394. Heat exchanger tube supports. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 30 Aug., 1968 [30 Aug., 1967], No. 39750/67. Heading F4S. A tube module for a heat exchanger comprises a number of superimposed layers, each layer being composed of a plurality of parallel tubes of a synthetic plastics material and each layer being separated from an adjacent layer by a number of spaced rows 5a, 5b, 5c of fibres 4 disposed transversely to the tubes the fibres serving to reinforce synthetic plastics material holding the tubes in position. A further plurality of fibres 8 running transversely of the tubes 1 and the fibre 4 may be provided also to separate the tubes. The parallel tubes in a layer are formed from a continuous length of tubing and the fibres interposed therebetween are cast into the synthetic plastics material to form tube plates 2 and a wall 3. The return bends of the continuous tubing are then cropped. The fibres which may be of glass are secured to the tubes 1 by first dipping the fibres in a liquid plastics material and the module fabricated in a loom. The casting may be performed by allowing the casting material to float on a liquid about one row of fibres at a time (Figs. 4A, 4B, Provisional).

Abstract: 1,274,493. Induction electricity meters. COMPAGNIE DES COMPTEURS. Aug. 8, 1969 [Aug. 8, 1968], No.39830/69. Heading G1Q. An induction motor meter for a four wire, three phase supply incorporates two rotor discs 1, 2 solid with and spaced along a common shaft 3, there being respective pairs of stator windings for each phase, two of the pairs co-operating with the disc 2 and the third pair co-operating with the disc 1. Each pair comprises a first, (current) winding, 42, 52, 62 respectively in the space between the disc and a second (voltage), winding 41, 51, 61 respectively on the opposite side of the respective disc outside the space. The magnetic circuit of the first winding of the third pair partially overlaps the magnetic circuits of the first windings of the other two in a longitudinal direction parallel to the shaft, to reduce the spacing between the discs. The planes of the first two pairs of windings are slightly inclined to the disc diameters parallel to the place of the third pair and the centres are slightly displaced to the plane of this diameter, to compensate for error due to change in the order of phase succession. The arrangement is such as to reduce stray coupling between the different electromagnetic circuits.

Filed: 1970-08-21
Abstract: 1284966 Piezo-electric transducers MOTOROLA Inc 21 Aug 1970 [23 Sept 1969] 40319/70 Heading H4S A disc of polarized piezo-electric ceramic material is stressed into a dish-shaped configuration and confined in that configuration by a frame attached to the perimeter of the disc. Electrodes are formed on the opposite major surfaces of the disc. The disc may function as the diaphragm of a loudspeaker or transmitter since it can be sufficiently thin to provide a good impedance match to air. By proper selection of materials and dimensions a wide frequency response may be obtained. A disc 10 (Fig. 1) of barium titanate has electrodes 11, 12 applied by plating, sputtering or painting. The electroded disc 10 is placed in a groove 14, 15 in a ring 13 of tungsten, tungsten carbide, alumina ceramic or molybdenum. A weight is applied to the centre of the disc to dish the disc. A unidirectional electrical field between the electrodes 11, 12 effects permanent polarization. The perimeter of the disc 10 is cemented into the groove 14, 15 by epoxy cement. Upon application of a signal current, the disc 10 alternately expands and contracts within its elastic limit. The movement is translated into movement perpendicular to the plane of the ring 13. The ring 13 has torsional characteristics to follow the movements of the disc. To minimize tendency of the disc 10 to fracture, a thin film of polyethylene terephthalate may be cemented to one or both major surfaces. The electrodes may be over this film. One or both electrodes 11, 12 may form a resistive conductive coating. A paper cone may be attached to the centre of the diac 10 to enhance low frequency response. It is also suggested to use a ring (23), Fig. 6 (not shown), having its inner surface in the form of a circular knife edge against which the dished disc is wedged.

Abstract: A "crystalline fraction" (defined as alkali metal salts of sulphuric acid secondary alkyl esters in which at least 90% of the molecules have entrenched alkyl groups containing 8 to 18 carbon atoms inclusive and the sulphate group is attached to the second carbon atom of the alkyl chain) is separated from an aqueous mixture of alkali metal monoalkyl sulphates formed by sulphating olefins by adding to this mixture a monohydric aliphatic alcohol that has a boiling point exceeding 100 DEG C. and is liquid and immiscible with water at 20 DEG C., allowing the resultant mixture to settle to an aqueous layer and an alcoholic layer, separating the alcoholic layer, distilling water from the alcoholic layer to leave a substantially water-free alcoholic solution, cooling the solution to crystallise the fraction and isolating the resultant crystals. Specified alcohols are methyl isobutyl carbinol, 1-hexanol and oxo-alcohols. In the examples, methyl isobutyl carbinol is added at 60 DEG C. to a solution of sodium alkyl sulphates and, after settling, the alcoholic layer is distilled leaving 0.2% water. Acetone is added before or after cooling to help crystallisation. On cooling, the crystalline mass is filtered or centrifuged leaving the "crystalline fraction". Specification 858,500 is referred to.
