Title: Rolling-compressing apparatus
IPC: B30B11/22
Filed: 1974-01-24
Abstract: 1466305 Briquetting apparatus J MOLITORISZ 24 Jan 1974 [29 Jan 1973] 03259/74 Heading A2B In a roller type briquetting apparatus, the axes of rotation of the rollers can be skewed from substantially parallel to the fodder chamber when at rest to skew thereto. The apparatus comprises a core forming channel defined by a plurality of compression rollers arranged circumferentially of the channel and extending longitudinally thereof with a transverse inlet between two of such rollers. One set of ends of said rollers is supported by a roller drive gear box arranged to drive at least one of the rollers, the gear box being mounted for pivotal movement about an axis extending longitudinally of the channel and arranged between the axes of said rollers. The gear box is biased to a rest position in which the axes of said rollers are substantially parallel to the axis of the channel and the input shaft of the gear box is so disposed relative to the axes of said rollers that when the input shaft is driven it exerts a torque on the gear box in opposition to the bias thereon so as to rotate the gear box from said rest position if the torque exceeds a predetermined value, thus skewing the axes of said rollers relative to the axis of the channel so that the rollers exert an axial force on a core of material e.g. fodder within the channel. The rotational movement of the gear box may be limited by adjustable stop means which serve additionally to define the rest position. Preferably the rollers include a primary receiving section and a secondary finishing section, an axial interspace being formed therebetween, and a cutter blade may be arranged to operate in the space between the sections to cut the core in the channel into briquettes which are further rolled by the finishing section prior to discharge from the apparatus.

Title: Improvements in the production of coloured products containing organic film-forming substances
IPC: C08J3/215
Filed: 1940-02-21
Abstract: 538,958. Cellulose derivative and synthetic resin compositions ; artificial filaments &c. LORD. G., and REEVES, G. Feb. 21, 1940, No. 3273. [Classes 2 (ii) and 2 (iii)] [Also in Group III] A coloured product is obtained by precipitating a colouring matter in finely divided form in an aqueous liquid, replacing water of the wet colouring matter by a liquid which is miscible with a solution of a film-forming substance in an organic liquid, the replacement being effected while maintaining the colouring matter wet with liquid, mixing the wet colouring matter with the solution of the film-forming substance and then precipitating the coloured filin-forming substance. A solution of the coloured product may be used for the production of artificial filaments, films, and the like. The water of the wet colouring matter may be displaced by a solvent of the film-forming substance. The coloured solutions may be precipitated by treatment with a non-solvent so as to obtain the coloured film-forming product which is subsequently worked up to any desired form. In an example, a vat dyestuff dissolved in sulphuric acid at 0‹ C. is poured into a large amount of water and crushed ice. The dyestuff is precipitated in finely divided form, filtered, washed, and pressed. It is then rinsed with acetone and ground with more acetone in a pebble mill. The paste is added to a solution of cellulose acetate and the solution is then poured into. water to precipitate the coloured cellulose acetate. Dyestuffs which may be used are those of the indigoid, thioindigoid, anthraquinone, and dibenzpyrenequinone series, phthalocyanine dyes, azo dyes, or water-insoluble bases of basic dyes. Inorganic pigments may be used. A deeply coloured product may first be produced and this mav be mixed with an uncoloured solution of film-forming substance to give a final product of the desired shade. The film- or filamentforming substance may be cellulose propionate, butyrate, aceto-propionate or other cellulose ester or ether, or polyvinyl acetate.
Patent GB-620951-A (GB)
Title: Improvements in or relating to refrigerating apparatus
IPC: F25B47/02
Filed: 1947-02-04
Abstract: 620,951. Refrigerating; thermostats. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 4, 1947, No. 3291. Convention date, Feb. 5, 1946. [Classes 29 and 64(ii)] In a compression refrigerating system, defrosting is effected by flooding the evaporator tube with warm liquid refrigerant normally retained in a reservoir 20, the refrigerant being prevented from entering the compressor in liquid form by the suction pipe being at least in part in heat exchange relationship with the hot gas line. As shown in Fig. 1 refrigerant flows from compressor 10 through a pipe 14, condenser 15, capillary tube 16, and a narrow pipe 18 to the reservoir 20 whence it flows through another narrow pipe 22 to evaporator 26. The suction conduit 30 is in heat exchange relation with the pipe 14 and capillary tube 16. An inverted U-tube 36 is connected between the reservoir 20 and the input line 24 to the evaporator 26. To defrost, a switch 42 is closed to apply current to a heater 38 which heats the pipe 18 and raises the pressure in reservoir 20 and liquid refrigerant is forced from the reservoir through the tube 36 and floods the evaporator and suction line 30. Liquid is prevented from reaching the compressor 10, since it is vaporized by the warm gases in pipe 14. Alternatively the element 38 may heat the reservoir 20 directly. In a modification shown in Fig. 3 refrigerant flows from condenser 15 to reservoir 50 and then through pipe 52 and expansion valve 54 to the evaporator 26. Valve 54 is thermostatically controlled by elements 62, 64, each of which is large enough to hold all the liquid medium filling the sealed system. To defrost, the element 62 is heated by element 66 and thus the valve 54 opens wide and liquid refrigerant floods the evaporator 26 and suction line 30. In the event of liquid refrigerant approaching the compressor 10, the element 64 will be cooled and will close the valve 54 more or less until the liquid-vapour boundary recedes along the pipe 30. A heating element 70 at the evaporator inlet 24 accelerates the refrigerant flow and defrosting action.
