Title: Process for preparing a solid substance containing ethyl alcohol
IPC: A23L29/00
Filed: 1967-05-06
Abstract: Lactose anhydride is treated with ethyl alcohol so as to cause the ethyl alcohol to be asborbed by the lactose anhydride. An additive such as flavouring, colouring, medicament or perfume may be associated with the lactose anhydride and/or the ethyl alcohol before the absorption treatment, or with the treated product. Additives: flavouring agents such as fruit juice extract, hop extract, dried bonito extract, spice extract, amino acid, common salt, malt extract, glycerine, sodium cyclamate, tartaric acid, malic acid, succinic acid, sodium malate, potassium malate and sodium bicarbonate, alcoholic beverages such as brandy, whisky, sakÚ, wine or beer (also cocktails), colouring agents such as caramel, medicinal agents such as a vitamin or hormone, and perfume agents. According to the Examples: (1) 33 Kg. of crystalline lactose are heated to remove the water of crystallisation and to obtain 30 Kg. of lactose anhydride, in which 20 Kg. of ethyl alcohol are absorbed with stirring to produce about 50 Kg. of powder. The powder can be used in confections such as chocolate or chewing gum. Alternatively, the powder is dissolved in water to produce an alcoholic beverage. (2) A mixture of lactose anhydride and condensed grape juice is dried to obtain lactose anhydride containing a condensed fruit juice, and 95%-ethyl alcohol, in which a small amount of a perfume agent and glycerine have been dissolved, is absorbed by the lactose anhydride. The product is then mixed with tartaric acid, malic acid, succinic acid, potassium malate and colouring to give a "grape wine powder". The powder can be formed into granules, lumps or tablets. (3) 95%-ethyl alcohol containing dissolved ingredients of hops and malt, is absorbed on lactose anhydride. The product is then mixed with amino acid powder, caramel powder, malic acid, tartaric acid and sodium bicarbonate to give a "powdered beer". (4) A seasoning is prepared by absorbing an extract of bonito in ethyl alcohol, on lactose anhydride prepared by spray-drying a solution of crystalline lactose in an aqueous extract of bonito. (5) 99%-ethyl alcohol containing dissolved orange juice and perfume, is absorbed on lactose anhydride containing gelatin and sodium cyclamate. The product may be added to the raw materials used in the production of cakes.

Title: Apparatus for Wet Screening Solid Particles.
IPC: B07B1/00
Filed: 1968-03-23
Abstract: Apparatus for wet separating loose solid material, e.g. plastics granulate, into fractions according to size comprises a screening deck 4 formed by longitudinally inclined bars 5 which are clamped at their upper ends and free at their lower ends and on top of which the material to be screened is fed with liquid at the upper end of the deck, and a partition wall 9 extending downwardly from a position spaced from the bars near the lower end of the deck for separating material which discharges through the deck from material which discharges off its lower end, the wall 9 being so placed that liquid dripping from the lower extremities of the bars falls to the same side of the wall as material discharging between the bars whereby any undersize fraction material entrained with the water is not discharged with the oversize fraction material. The material is pumped with water into a compartment A through a feed opening 15 and flows over the top end of the deck, the undersize and oversize fractions being collected in compartments B and C respectively. The bars which are circular in cross-section, and which may be solid or tubular, diverge from one another in the direction from the upper to the lower end of the deck so that the deck is self-cleaning. The bars are preferably curved back at their lower extremities as at 16. In the latter case, the downstream end regions of the bars may extend beyond the partition wall 9. The side walls 2, 3 of the apparatus may be divergent or, as shown, they may be fitted with divergent guides 12, 13 to prevent material falling between the side walls and the outermost bars.

Title: Novel precipitated siliceous products
IPC: A61K8/00
Filed: 1976-03-11
Abstract: A method for producing a precipitated silicon dioxide having a new combination of physical and chemical properties is disclosed. The pigments are produced by acidulating a solution of an alkali metal silicate with an acid under controlled precipitation conditions. The aqueous reaction medium comprising the precipitated silica is then post-conditioned by introducing a second silicate solution into the reaction vessel and thereafter adding additional acid to react with the said second silicate solution. By varying the amount of the silicate employed in the post-conditioning step, a product is obtained which has a unique combination of physical and chemical properties including reduced wet cake moisture content, high surface areas and oil absorptions, improved surface activity, friability, wetting characteristics, and the like. The product has particular utility for use as a rubber reinforcing agent because of its increased surface activity and oil absorption, etc. The product, however, may be used in paints, paper, detergents, dentifrice compositions, molecular sieves, and polymeric compositions. An unexpected discovery of the invention involves the production of a rubber reinforcing silica which has a decreased wet cake moisture content. In one particularly advantageous embodiment, an adduct material, such as aluminum, is added to control the refractive index and surface area of the product.

Title: Refrigeration circuit utilising heat dissipated by condenser - uses condenser cooling water to supply central heating system
IPC: F25B29/00
Filed: 1978-05-10
Abstract: A refrigeration circuit consists of a compressor (16) which supplies refrigerant to a condenser (17 or 18). The liquid refrigerant passes through the reservoir (19) the drier (20), the sight glass (21), the expansion valve (11), and evaporator (12) to return to the condenser (16). To use the heat dissipated by the condenser, it is cooled with water through the pipes (22). Using cooling water enables the condenser to be placed in any convenient position (e.g. 171). The heat in the cooling water is removed by a fan and the air used for heating purposes elsewhere. This heating can be supplemented with hot water, from a tank controlled by a valve. When heating is not required, the secondary condenser (18) is used which is air cooled by the fans (32).
