Title: A process for working up household refuse for moulding purposes
IPC: B03B9/06
Filed: 1932-08-10
Abstract: In a process for working up house refuse for moulding purposes the refuse is freed from metal bodies, pulverised, sterilized to destroy germs injurious to health by boiling with water and lime, and mixed with one or more of the subsubstances specified below for rendering the animal and vegetable constituents organically inert; the resulting mass is then moulded, the bulk of the liquid being removed from the mass before or during moulding and the moulded articles dried.  The substances used for rendering the p  animal and vegetable constituents organically inert are mercury, copper or other heavy metal salts, formalin, organic acids, or inorganic acids such as sulphuric, nitric or phosphoric acids. After the animal and vegetable constituents have been rendered organically inert the mass may be treated with substances which wholly or partly break down or disintegrate the fibrous substances contained in the refuse e.g., the mass may be treated with boiling soda lye or sulphite lye and the mixture then acidified to reprecipitate the dissolved cellulose substances.  About 3 per cent of aluminium sulphate may be added during the stage of rendering the animal and vegetable constituents organically inert in order to obtain a greater firmness and resistance to the action of water in the final product.  The refuse used may be wholly or partly freed from ash constituents.  The mass may be moulded into wall-boards, slabs, ceiling and other building materials.

[Class 46.] Vertical filter cells, immersed in material to be thickened, rotate as a whole about a common vertical axis and each individual cell rotates about its own axis during a period while it is being cleaned by a reverse flow of compressed air. The cells 73 are carried by plates 16, 17, fixed to a sleeve 15, which is attached to the moving part 18 of a distributing valve and can be clutched to a central shaft 5 so as to rotate therewith. A flange 37 on the lower end of an elbow pipe 44 is pressed on the upper end of the suction pipe 25 of each cell by a spring 38 which engages a hinged stirrup 39. The pipe 44 has a rectangular section so that the arms of the stirrup 39 will prevent its rotating. The suction pipe 25 is connected by a pipe 44, a glass tube 46 and a pipe 47 with a cut-off cock 49 to an aperture in the plate 18. The upper plate of the distributer has connections to suction and compressed air so that as they rotate each cell reaches a position in which a back flow of compressed air detaches the cake therefrom. Each element as it comes into the position in which it is connected to the source of compressed air is rotated by a driving-wheel which is carried by a pivoted arm and pressed by a spring into engagement with a spur or friction wheel 27 keyed on a collar 26 fixed to the suction pipe 25 of the element. The material under treatment is supplied through an inlet 2 to the tank 1 which may have a jacket 4. The discharge of the thickened mud through an outlet pipe 3 is promoted by agitators 67, 69 on a shaft 8 rotating with the shaft 5. Each cell 73 comprises a cylindrical filtering wall with end caps 71, 72 and an inner air-tight body 74 held in position by tie rods 75.

Abstract: 1,221,046. Crimping yams. GLANZSTOFF A.G. 5 May, 1969 [7 May, 1968], No. 22742/ 69. Heading D1F. In apparatus for continuously crimping, and, perhaps, also stretching, yarn by passage between intermeshing "gear" teeth which may be directly or indirectly heated, radially extending teeth are formed as circular rings on opposed end faces of two cylinders the axes of which are inclined to each other (and possibly intersect) so that a segment only of the rings of teeth are in continuous meshing engagement. One cylinder comprises pins, around the inner periphery of the ring, which engage in corresponding bores in the other cylinder to ensure that a rotary drive is synchronously and positively transmitted from one (belt driven) cylinder to the other, that the flanks of opposed teeth are not in contact when the teeth intermesh and therefore the yarn is not pinched therebetween, and that the yarn, whilst supported by the pins, is not pulled away from the ring of teeth towards the centre of rotation of the gear wheel by the tension therein., One gear wheel may be axially displaceable and biassed by a tensioning element towards the other gear wheel.

Title: Improvements relating to carboxylic acids and esters thereof
IPC: C07C35/205
Filed: 1962-06-19
Abstract: The invention comprises 1-alkylcyclo-undecane-1-carboxylic compounds of the formula <FORM:1005642/C2/1> in which R is an alkyl group of 1-4 carbon atoms and R1 is hydrogen or an alkyl group of 1-4 carbon atoms.  The novel compounds may be made by reacting sodium-containing cyclododecanone (made from cyclododecanone and sodamide) with an organic alkylating agent, such as an alkyl halide or sulphate, separating from the product the resulting 2-alkyl-cyclododecanol and treating it at 18-22 DEG  C. with a halogen in an organic diluent which is inert under the operating conditions whereby a 2-halo-2-alkylcyclododecanone is formed, and treating the 2 - halo - 2 - alkylcyclododecanone with an alkali metal hydroxide followed by acidification whereby it is converted into a 1 - alkylcycloundecane - 1 - carboxylic acid. The ester may be formed by esterification with an alkanol of 1 to 4 carbon atoms. When the alkyl radical is of the type-CH2R11, where R11 is a hydrogen or alkyl radical, 2-alkyl-cyclododecanones for use in the above process may be made by first forming 2-methylene cyclododecanone and hydrogenating it, for example using hydrogen in the presence of Raney nickel at 15-20 DEG C., or reacting with an alkyl magnesium halide.  The preparation of 2-methylenecyclododecanone by converting cyclododecanone to a quaternary ammonium salt of N,N-dimethylaminomethyl cyclododecanone and treating the latter with an alkaline agent is described in Specification 1,005,643. Detailed examples are given.
