Title: A process for treating oil containing liquors from the wet rendering of oil-containing materials
Inventor: ONARHEIM THOR
IPC: C11B1/00
Filed: 1954-08-20
Abstract: Oil-containing liquors from oil production by wet rendering of fatty oil-containing materials are treated to separate the oil in a series of steps comprising a preliminary centrifuging step with a low degree of oil separation, an evaporating step applied to the remaining liquid, and a final refining step of the latter residual liquid.  The liquors may be de-sludged in a series of such steps made between the separation steps.  The oil-containing liquors treated are preferably press liquors from the wet rendering of herrings.  The preliminary centrifuging removes a bulk of oil before heating the liquors; the evaporation of the watery liquid produces a liquid containing solids of value as animal food; and the final refining step, which may be another centrifuging, recovers the remaining oil therefrom.  The final de-sludging and final separating steps are preferably effected at a fairly high temperature, e.g. 80-100 DEG C.  The evaporation step is thus averaged to finish at such a temperature.  The evaporation apparatus may comprise a vacuum evaporator having three or more stages using decreasing temperatures such as 116 DEG C., 90 DEG C. and 60 DEG C. respectively, live steam being used to heat the first stage and vapours from preceding stages being used to heat the second and third stages.  The liquor is treated in the first stage, then in the third stage and finally in the intermediate stage.  The liquors may be acidified before the final separation and final de-sludging steps, e.g. with sulphuric acid to a pH of 4.2.

Title: Treatment of animal fibres
IPC: D01C3/00
Filed: 1936-09-08
Abstract: The spinning of animal fibres, particularly short fibres such as rabbit fur or hair and feathers, is facilitated by treating the fibres with a solution of sericine.  The fibres may first be degreased as by an aqueous mixture of trichlorethylene and triethanolamine, followed, if desired, by soap washing.  For the main treatment there is used a solution of sericine in an alkali preferably a soap, a suitable solution being boiled-off liquor; and to the solution an alkali sulphocyanide may be added, or the latter may be applied as a separate treatment.  After treatment, the fibres are dried.  Fibres so coated and weighted do not exhibit electrical effects, and they are free from "fly" in spinning and from "shedding" when spun; they may be spun with other fibres; and their dyeing is facilitated.ALSO:A coating solution for animal fibres consists of a solution of sericine in an alkali, preferably a soap.  A convenient solution is boiled-off liquor.  To the solution alkali sulphocyanide may be added.

Abstract: 404,399. Harvesting tea, flax, or hops. BUDD, A. G., and BARTON, H., Station Garage & Motor Works, West Moors, Wimborne, Dorset. Sept. 5, 1932, No. 24756. [Class 6 (iii).] In a machine for plucking poultry, stripping tea plants, pulling flax, or picking hops, of the kind comprising gripping-members mounted on rotary discs, the gripping-members consist of spring blades 5 secured, e.g. by riveting, at the leading ends to the sides of the discs 3, the trailing ends being free and arranged to come together in pairs to form the grippers. The blades 5 are stiffened by spring blades 11 secured to the discs and arranged behind the blades 5. The discs 3 are spaced by, and are secured to, spacers 4 which are keyed to the hub 1, and the assembly of discs and spacers are held together by a screwed ring 13. Means 7, 8 for separating the grippers 5 are arranged between each pair of discs 3, the means 7, 8 being secured between spaced fibre rings 6 loosely mounted on the spacers 4. The means 7, 8 are prevented from rotation by a bar 10 which passes through aligned holes in the parts 8. The bar 10 may be adjustable to vary the position at which the grippers snap together on being released by the members 7, 8. In operation, the bird, or article to be plucked, is held against an opening in the casing, which at the plucking position, is curved to the radius of the gripper drum, and the feathers, erected by draught induced by a fan, project between the grippers 5 which have been opened by the members 7. On being released by the members 7, the grippers 5 snap together and grip the feathers. The tips of the grippers 5 are curved away from each other, to avoid sharp edges contacting with the members 7, 8. The plucked feathers are released by the members 8, which positively eject the feathers and clean the grippers.

Title: Process for the separation of constituents from gas or vapour mixtures
IPC: B01D51/10
Filed: 1929-08-13
Abstract: 338,497. Caro, N., and Frank, A. R. Aug. 13, 1929. Nitric acid; nitrogen tetroxide; calcium cyanamide; hydrocyanic acid; ammonium carbonate and other ammonium salts.-Mixtures of gases or vapours, obtained as the products of chemical reaction, are treated by a process of condensation in which the temperature of the cooling agent is kept as far as possible below the temperature of the gases issuing from the condenser, when the large fall of partial pressure towards the cooling wall results in precipitation of one of the constituents, in solid or liquid form, without the dew point being reached in the bulk of the gas. A substance may be added to reactant gases and this substance, or its reaction products, removed by the process after passing the reaction zone but before further treating the mixture. Hot aqueous nitrous gases produced by combustion of ammonia, with the addition of steam, hydrogen, oxygen or sulphurous acid in some cases, can be treated to separate the water, free from, or poor in nitric acid, while avoiding a low temperature of the final gas mixture, the ammonia combustion apparatus, the heat utilizing boiler, and the condenser being connected one behind the other. A more concentrated acid, together with saving in cooling surface, is obtained using mixtures rich in oxygen and in nitrogen oxides, prepared e.g. according to Specification 273,718, employing the present process of condensation. Mixtures containing nitrogen oxides and water vapour from other sources such as from oxidation of hydrocyanic acid with air or oxygen, with or without addition of water vapour, may be similarly worked up. The reaction of ammonia and calcium carbonate to give calcium cyanamide may be carried out, using the present process for removing the water formed, the unconverted ammonia, which is still at a comparatively high temperature, being again introduced into the process. The gas mixture resulting from the reaction between carbon monoxide and ammonia to produce hydrocyanic acid and water may be similarly treated. If excess of carbon monoxide is used formation of carbon dioxide occurs which retards the reaction, as is also the case in the cyanide formation referred to above when carbon monoxide is added. To avoid this, ammonium carbonate solution may be separated instead of water, without the gas mixture being saturated with the separated solution. Ammonium salts can be separated from other ammonia-containing gas mixtures, or ammonia separated in liquid form from mixtures such as from the ammonia synthesis.
