Abstract: 280,986. Downs, C., and Bellwood, R. A. July 21, 1926. Fats and fatty oils, extracting by solvents.-Palm and like oils are extracted without the use of steam or water by means of externally heated solvent while the pericarp is being stripped from the nuts. In the steamjacketed extractor 11 palm fruits are agitated in hot or boiling solvent by serrated blades 19 which are mounted on a rotating shaft 15 and alternate with stationary agitators secured to the extractor. The blades 19 are pivoted on hubs P so as to be displaceable in the path of rotation and give under abnormal pressure, but may be pivoted so as to be set or to give at an' angle to the path of rotation. In a modification the extractor and agitating shaft are vertical, and the extract flows through a perforated plate above which is a sweeper for ejecting the shredded pericarp and the cleaned nuts through a suitable orifice in the side; steam coils are arranged below the plate to maintain the temperature of the solvent. In further modifications, the digester described in Specification 241,298, [Class 58, Grain &c.], is slightly modified and used as an extractor, all the agitators may rotate, maybe some in opposite direction to the others, a plurality of agitating shafts situated laterally of a central one may be employed, or a shell or cage may be arranged adjacent the extractor walls, be fitted with agitators, and be rotated in the same or opposite direction as the central shaft.

Abstract: 595,716. Weighing-apparatus. ELECTROFLO METERS CO., Ltd., and BRIDGES, J. P. Oct. 24, 1945, No. 18254/44. [Class 143] [Also in Groups XXIX, XXX and XXXV] Apparatus for regulating the supply of material by a power-driven conveyer, in particular for the supply of solid or powdered fuel to the furnace of a steam generator, is controlled by the weight of material on the conveyer, the speed of which is also controlled by some other condition influenced by the rate of delivery, such as the load on electrical generators driven by the turbines to which steam is supplied, or the steam pressure, or the temperature in a building to which heat is supplied. As shown in the Figure, the fuel is supplied from a chute 11 and a hopper 12 on to an endless conveyer band 1 driven by an electric motor 5. The conveyer is mounted on a frame 10 which is pivoted on a horizontal axis 8 so that the weight of material on it operates through a connection 14, a weighbeam 15 associated with a regulator 16 of the type described in Specifications 463,326 and 463,549, [both in Group XXIX]. The regulator 16 is provided with an adjustable control spring 16' and controls a servo device operating a shutter 17 in the opening 13 of the hopper 12 to regulate the supply of the fuel on to the conveyer. The speed of the motor 5 is maintained constant by a governor 19 actuating a weighbeam 20 of another regulator 23 which controls a resistance 18 in the motor circuit. The speed of the motor can be adjusted by pressure of a fluid in a conduit 22 acting on a diaphragm 21 connected to the weighbeam 20, this pressure depending upon the condition, such as the load on electrical generators, in accordance with which it is desired to exercise control. Other types of conveyers may be used such as a rotating disc loading and unloading at different points on its circumference and the controlling shutter may operate horizontally instead of vertically. Liquids or semi-liquids may be delivered by the apparatus by providing the conveyer belt with a number of suitable receiving and discharging compartments. The movement of the conveyer or a part thereof under the weight may operate the damper controlling the supply of material directly and not through a servo device as shown.
