Patent GB-703451-A (GB)
Title: Branched chain orthosilicates
Inventor: MORGAN CLARENCE RICHARD
IPC: C07F7/04
Filed: 1951-08-08
Abstract: The invention comprises the following orthosilicates:-tetra 2-ethylbutyl, tetra 1, 3-dimethylbutyl, tetra 2-methylpentyl, tetra 1-ethylpentyl, tetra 1-methylhexyl, tetra 2-ethylhexyl, tetra "iso-octyl," tetra "nonyl," tetrakis (1-methyl-4-ethyloctyl) and tetrakis 2 (1, 3, 3-trimethylpropyl)-5, 7, 7-trimethyloctyl orthosilicates.  The orthosilicates may be prepared either by adding silicon tetrachloride to a slight excess of the required alcohol and when the reaction is complete distilling the mixture to remove excess alcohol, or by reacting ethyl orthosilicate with the required alcohol and distilling ethyl alcohol from the reaction mixture. The tetra "iso-octyl" orthosilicates are a mixture of orthosilicates derived from a mixture of 8 carbon alcohols where the alkyl radicals contain on the average two side chain groupings on a carbon chain of 4 to 6 carbon atoms said alcohols being derived from the reaction of olefins, carbon monoxide and hydrogen.  The tetra "nonyl" orthosilicates are a mixture of orthosilicates derived principally from trimethyl hexanols with dimethyl heptanols as a minor component and contain the 3, 5, 5-trimethylhexyl, 2-isopropyl-3, 3-dimethylbutyl and 2, 2, 4, 4-tetra methylpentyl radicals.ALSO:Mineral oil lubricants contain as an additive any one of the following organo-orthosilicates:-tetra 2-ethylbutyl, tetra 1, 3-dimethylbutyl, tetra 2-methylpentyl, tetra 1-ethylpentyl, tetra 1-methylhexyl, tetra 2-ethylhexyl, tetra "iso-octyl," tetra "nonyl," tetrakis (1-methyl-4-ethyloctyl) and tetrakis 2 (1, 3, 3-trimethylpropyl)-5, 7, 7-trimethyloctyl orthosilicate.  The tetra "iso-octyl" orthosilicate consists of a mixture of orthosilicates derived from a mixture of 8 carbon alcohols where the alkyl radicals contain on the average two side chain groupings on a carbon chain of 4 to 6 carbon atoms said alcohols being derived from the reaction of olefins, carbon monoxide and hydrogen.  The tetra "nonyl" orthosilicate is derived from a mixture of 9 carbon alcohols containing principally trimethyl hexanols wth dimethyl heptanols as a minor constituent and containing 3, 5, 5-trimethylhexyl, 2-isopropyl-3, 3-dimethylbutyl and 2, 2, 4, 4-tetra methylpentyl alcohols.

Abstract: 728,920. Pasteurizing liquids. SOC. POUR, L'EQUIPEMENT DES INDUSTRIES LAITIERES ET AGRICOLES, and SIDLER, W. J. July 24, 1952 [Oct. 19, 1951], No. 18812/52. Class 49. In pasteurizing a liquid such as milk or cream, a laminar stream of the liquid is rapidly heated to pasteurization temperature in two stages, the first stage being effected at sub-atmospheric pressure, the liquid is kept at pasteurization temperature for a desired time and then quickly cooled. In a preferred apparatus. the liquid is fed through an inlet 5 into a heating chamber comprising an evacuated compartment A and a compartment B, and is made to flow in a laminar stream over the inner cylindrical surface of the heated wall 1 of the chamber by paddles 7 attached to partitions 6 9, and 9a secured to a rotating shaft 4. The paddles may be oblique to the shaft. Preferably, the clearance between the paddles and the wall 1 should not exceed 0.5 m.m. and their peripheral speed should exceed 12 metres/sec. The paddles have notches K and L enabling gas-tight liquid seals to be formed at the partitions 9 and 9a. Compartment A is evacuated through an axial bore 10 and radial slots 11 in the shaft. The liquid may receive most of its heat in compartment A. The wall 1 is heated by hot fluid, e.g. steam, circulating through a jacket. The heated liquid is .then passed into a heat-maintaining space between a wall 2 and a drum mounted on the shaft, then through a cooling space between a wall 3 and a cylinder also mounted on the shaft and is finally discharged through an outlet 25. The drum and cylinder mav be united in a single drum 21, as shown, which carries battens 22 to provide laminar flow of liquid through the cooling space. The heatmaintaining space is lagged with heat-insulating material and wall 2 is insulated from the wall 3 by a layer 23 of this material. Liquid on its way to the inlet 5, or water, is passed through a jacket 24 to cool the liquid in the cooling space.

Filed: 1972-05-11
Abstract: 1373816 Moulding hollow ceramic articles ADVANCED MATERIALS ENG Ltd 11 May 1972 [5 June 1971] 19133/71 Heading B5A [Also in Division C7] Hollow ceramic ware is made by vacuum forming, pressure forming, blow moulding or back extrusion of a mass of plastic green mixture to extend the mass and increase its surface area. The form is then sintered or reaction bonded in a reactive gas atmosphere. The plastic mixture may be made by mixing the ceramic powder such as Si either with an alginate-water-glycerol mixture, a methyl cellulose-latex-silicone mixture, benzophenone, toluidene or diphenylamine. The vacuum forming technique may be drape; plug assist; vacuum snap back; inverted drape; air forming with plug assist; or billow. A sheet of the green mixture may be formed by pouring or spraying the mixture on a glass former or by dipping the former in the mixture. The mixture is set on the former by spraying with methylated spirits containing 30% calcium nitrate. The sheet is then vacuum formed into a crucible. Alternatively a lump of the mixture of putty like consistency is back extruded to form a crucible. The Si crucible is then reaction bonded by heating in N 2  to form Si 3 N 4 .

Title: Improvements in or relating to infusion apparatus
Inventor: POUGET LOUIS MARCEL
IPC: A47J31/50
Filed: 1934-06-29
Abstract: 421,515. Coffee urns. POUGET, L. M., 9, Rue des Feuillantines, Paris. June 29, 1934, No. 19207. [Class 129] In a coffee infuser, a compression bell causes the hot water to overflow peripherally on to the ground coffee. In operation, the vessel 1 is filled with water through a suitable place in the space 7. If the cock 10 is closed, the water will not rise to the top of the bell 8, but will cause a cushion of air 12 to form. The volume of this air cushion is determined by turning off the cock 10 at the correct time. When water in the vessel 1 is heated the air expansion and steam generation drives water into the bowl 2 through the peripheral channels 13 whence it percolates through the ground coffee 14 and into the beverage chamber 3. Coffee is drawn off from the chamber 3 by a cock, not shown. When a certain volume of water has passed into the bowl 2, stability results and no more water passes over. Further heating causes a fresh overflow. The frequency of these intermittent pulsations depends on the heating temperature and the dimensions of the spaces 8 and 7. The end of the infusion will occur when the steam and air in the space 12 passes below the skirt 6. Practical forms of the apparatus are described.
