Filed: 1974-03-15
Abstract: 1428310 Ice cream freezers IREKS ARKADY GmbH 15 March 1974 [20 March 1973] 11734/74 Heading F4H An ice-cream freezer and dispenser comprises an upper storage tank 1 connected by a replenishing duct 63 to a lower freezing cylinder 2 provided with a heater 83 and agitator 54, the heater being adapted to partially evaporate the contents of the freezing cylinder and the steam flowing into the storage tank heats the contents therein to a sterilization temperature. The freezing cylinder is formed by a thick-walled tube 35 in which a helical channel 36 is formed for the passage of a freezing medium and which is closed by a shrunk-on tube 39. The heater comprises electrical elements positioned in tubes fitted to the outer surface of the tube 39 and controlled by a thermostat having sensors on the cylinder and tank to prevent overheating of the contents of the cylinder and to terminate heating when pasteurization temperature is achieved in the tank. A driving motor for the agitator 54 and scraper blades 68 which are mounted-on a shaft 53 is connected in the electrical circuitry for the heater by passing the thermostat associated with the cylinder. Compressed air is fed periodically into the cylinder through an inlet 58 and the ice-cream is dispensed through a piston valve 76 controlling an outlet orifice 78. The storage tank 1 has an agitator 18 and a double walled cover 6 locked in position by cam action.

Title: Improved cigarette filter and process for manufacturing same
IPC: A24D3/02
Filed: 1954-04-23
Abstract: A cigarette filter comprises a piece of tow of substantially parallel regenerated cellulose filaments having a rough irregular surface and cavities due to the use in filament formation of a viscose in which air or other gas is finely divided, the viscose being extruded through a multiple-orifice spinneret into a coagulating bath from which the tow thus formed is removed at considerably less than, e.g. approximately one-fifth of, the linear extrusion speed, washed and dried.  Before washing, the tow may be treated with hot water to complete the regeneration. Before drying, the tow is desulphurized and bleached and, before or after drying, it may be coated with a binder by being immersed in an aqueous solution of a cellulose ether, e.g. hydroxyethyl cellulose, methyl-cellulose or carboxymethylcellulose, being subsequently passed through a shaping device to form a round bundle of filaments and subjected to a vacuum treatment to remove excess solution, and being finally dried in a channel-like drier to retain its circular formation.  Adsorption agents such as activated silica gel or activated alumina may be incorporated, e.g. by adding them to the binder solution. Quantitative process examples are given.ALSO:A cigarette filter comprises a piece of tow of substantially parallel regenerated cellulose filaments having a rough irregular surface and cavities due as described to the use in filament formation of a viscose in which air or other gas is finely divided, the viscose being extruded through a multiple-orifice spinneret into a coagulating bath from which the tow thus formed is removed at considerably less than, e.g. approximately one-fifth of, the linear extrusion speed, washed and dried.

Abstract: 527,887. Supply meters. CHAMBERLAIN & HOOKHAM, Ltd., JAMES, S., and WHEELER, A. J. April 22, 1939, No. 12178. [Class 37] [ Also in Groups XXXIV and XXXV] The brake magnet has a flux-diverting member made from a thin sheet of material the permeability of which decreases with increase of temperature, this member extending away from the magnet gap so as to modify the fringe of flux adjacent to the gap and being also such that it readily responds to temperature changes. A C-shaped permanent magnet a acting on a rotor disc b has attached to one of its poles a flux-diverting member e about 0.03 inch thick. The member b may be made from an alloy of 29 per cent. nickel, 70 per cent. iron, 0.8 per cent. manganese, and 0.2 per cent. carbon, or from an alloy of 70 per cent. nickel and 30 per cent. copper. The member is formed of a strip of sheet material bent so that the operative portion e is in the plane of the pole face and the remaining part f lies in contact with one side of the magnet. A clamping plate g is placed over the portion f and is secured to the magnet by a nut h on a screw i passing through one side of the magnet, the portion f, and the plate g. At normal temperature the fluxdivertive member e increases the stray flux or fringe at the adjacent side of the magnet gap, decreasing the flux density in the gap. On rise of temperature the member e quickly responds and causes a decrease of the flux in the fringe with consequent increase of the flux density in the gap. The'braking effect may be adjusted by varying the position of the brake magnet a relatively to,the rotor. The screw i has an enlargement k through which passes an adjusting screw m on a supporting bracket n. The enlargement k is formed with a screw-threaded part o which passes through a slot in the bracket n and carries a securing nut.q.. A-flux-diverting member may be arranged at. each side of one pole or at one or both sides of each pole.

Abstract: The invention comprises 4-chloro-3-oxo-D 4-cyclopentanophenanthrenes of the androstane and pregnane series having apart from the substituent in the 17-position the general formula: <FORM:0792727/IV (b)/1> wherein R represents: <FORM:0792727/IV (b)/2> and the preparation thereof by chlorinating the required 3-oxo-D 4-cyclopentanophenanthrene of the androstane and pregnane series and treating the resulting 4 : 5-chloride with a base to remove the elements of hydrogen chloride.  The chlorination may be effected in an organic solvent with approximately one molar equivalent of chlorine (preferably also dissolved in an organic solvent) at a temperature not in excess of 40 DEG  C., a temperature between - 35 DEG  C. and + 5 DEG  C. being particularly suitable.  The chlorination is preferably effected in the absence of light. Suitable organic solvents are dioxan, ether, carbon tetrachloride and a lower aliphatic acid.  The base used to remove the elements of hydrogen chloride may be a tertiary base such as collidine, lutidine or pyridine.  The removal of the elements of hydrogen chloride may also be carried out by percolating a solution of the 4 : 5-dichloride, e.g. in benzene, through a column of alumina.  Suitable reactants for the above process are androst-4-ene-3,17-dione, methyltestosterone and esters thereof, testosterone and esters thereof, 17-chloroandrost-4-en-3-one, progesterone, pregn-4-ene-3,20-diones containing an oxo, hydroxy or acyloxy group at C11, e.g. 11a -hydroxy-progesterone, pregn-4-ene-3,20-diones containing a hydroxy or acyloxy group at C17 and/or C21, and pregn-4-ene-3,20-diones containing hydroxy or acyloxy groups at C17 and C21 and an oxo, hydroxy or acyloxy group at C11, e.g. cortisone acetate. The esters of testosterone may be derived from acids containing not more than 12 carbon atoms, e.g. the ester may be the propionate, trimethylacetate, valerionate, heptylate, undecylenate, cyclopentylpropionate, cyclohexylpropionate, phenylacetate, phenylbutyrate or hexahydrobenzoate of testosterone.
