Patent GB-1042138-A (GB)
Title: Production of organotin compounds
Inventor: COATES HAROLD
IPC: C07F7/22
Filed: 1962-08-15
Abstract: An alkyl, particularly dialkyl, tin ester is prepared by reacting tin, or an alloy thereof, with an alkylating ester in the presence of an alkyl bromide and/or iodine, e.g. 0.05-0.4 mols per mol alkylating ester.  An alkylating ester is defined as an alkyl ester of an oxy-acid that is capable of reacting with stannic bromide or icdide to produce the corresponding alkyl halide, for example an alkyl sulphate, sulphonate, sulphite, phosphate or phosphite. The alkyl groups in the ester may have 1-20 carbon atoms, may have inert substituents, e.g. fluoro-, cyano-, ether or thio-ether groups, and they are preferably the same as the alkyl groups in the alkyl halide. Suitable esters are butyl, amyl, hexyl, heptyl and octyl esters, particularly tri-n-butyl and tri-n-octyl phosphates. Reaction may take place at 80-300 DEG  C. in presence of one or more of an organic base, e.g. pyridine, a non-oxidizing acid, e.g. phosphoric or p-toluene sulphonic acid, metals, which may be alloyed with the tin, such as copper, silver, magnesium or aluminium, and/or salts of these metals.  Optionally a diluent, e.g. halogenated hydrocarbons or high boiling ethers may be used, and in addition a minor proportion of an alcohol, preferably that corresponding to the alkyl group in the ester, may be present.  The alkyl tin ester may be isolated by, e.g. filtration, extraction or distillation, or may be hydrolyzed in situ to the alkyl tin oxide, alkyl stannoic acid or salt thereof.

Abstract: A devitrified glass coating composition is made by mixing a powdered glass (i), and another powder (ii), and sintering for a time sufficient for the mixtures of (i) and (ii) to react together and form a predominantly crystalline composition.  Glass powder (i) has composition, in per cent by weight: SiO2, 54-66; Al2O3, 17-27; MgO, 4-12; CaO, 0-10; BaO, 0-1; B2O3, 0-3; TiO2, 0-3; F, 0-0.3; Na2O and/or K2O, 0-0.4.  The mixture of powders (i) and (ii) comprises the following percentages by weight of the following components of powder (ii): Al2O3, 0-22; Li2O, 0-12; MgO, 4-55; SiO2, 0-10; these components being in the form of Li2CO3, LiAlO2, Li2SiO3, MgO, MgCO3, MgSiO3 or Al(NO3)3.  The sintering may be conducted at 1150-1250 DEG C.  The mixture, with or without pre-sintering, at 1000 DEG  C. and further comminution, may be mixed with organic binders and ground to a pasty or thin sprayable consistency.  The binders may be e.g. oils, turpentine, or amyl acetate/nitrocellulose. Substrates include quartz quartz glass, porcelain, ceramic, e.g. cordierite, sintered corundum, metals and metal alloys, e.g. W, Mo, Nb, Ta and their alloys, and Cr/Al/Fe alloy.  The layers may be applied e.g. by hand, by dipping or by spraying.  The firing may be performed in an electrically heated oven, or by direct electrical heating of the metal substrate. The layers can be placed as a fusion cement between two parts to be united, and may have thermal expansion coefficients adapted to the parts to be united, in the range (20-107) x 10-7/ DEG C.

Title: Improvements in or relating to high frequency compressional-wave transmission and receiving apparatus
IPC: G10K11/00
Filed: 1945-11-22
Abstract: 644,288. Subaqueous audible and like signalling apparatus. RAYTHEON MANUFACTURING CO. Nov. 22, 1945, No. 31493. Convention date, Oct. 6, 1941. [Class 118 (ii)] [Also in Group XL (b)] Relates to compressional wave transducer systems in which plane waves are transmitted from one medium to another normally through the skin of a vessel, the transducer being located in a tank with reflecting walls which is mounted against the skin. According to the invention a plate having a substantial mass is positioned in the tank parallel to the skin. the plate, skin and intervening medium forming a half-wave resonant system whereby loss of energy caused by reflections at the surface of the skin is reduced. The invention which is particularly applicable to submarine echo-sounding systems is described as applied to the transducer system in U.S.A. Specification 2,332,541 in which a magnetostrictive oscillator 13<SP>1</SP> is mounted in a tank 2 which is clamped to the inside surface of the steel skin 1 of a ship, the inside of the tank being filled with fluid and the oscillations initiated at the surfaces 14<SP>1</SP>, 15 of the oscillator being reflected by the sloping sides of the tank to form a plane wave front travelling normal to the skin. In accordance with the present invention, a steel plate 5 is adjustably mounted parallel to the skin by means of the threaded rods 11, and perforations 10 are provided when the fluid in the space 8 between the plate and the skin is the same as in the rest of the tank. If the space 8 is filled with a different fluid the perforations are omitted and the plate 5 is arranged to make a fluid-tight fit with the walls of the tank ; alternatively the space 8 may be filled with a solid, plastic or semi-plastic material. When the space 8 is filled with fluid, partitions may be inserted, Fig. 3 (not shown), constructed of sound insulating material such as spongerubber or cork in order to damp out transverse vibrations. The position of the plate 5 is adjusted so that the plate, skin, and intervening medium forms a half-wave resonant system with a nodal surface located in the medium. When the plate and skin have the same thickness and are made of the same material, the resonant system is symmetrical with respect to the nodal surface and a true impedance match is obtained between the medium in the tank and the external medium but when this condition does not obtain, optimum transmission is produced by tuning the tank so that the transmission path from any point on the oscillator 13<SP>1</SP> to the inner surface A of the plate 5 is an integral number of half-wavelengths either by compressing the gasket 4 to bring the flange 7 of the tank close to the skin or by adjusting the position of the back plate 30. In general the thickness of the skin is less than #/4 and may be less than #/8 and the thickness of the plate 5 may be less than that of the skin.
