Title: Improved method and apparatus for separating the kernels from cashew and like hard-shelled nuts or seeds
IPC: C09F5/04
Filed: 1951-09-07
Abstract: In a process for the ejection and separation of the kernels from the shells and epidermis (or testae) of cashew and like hard-shelled nuts or seeds in which the shells contain phenolic or resinous substances, the nuts or seeds are subjected to a preliminary softening treatment and are subsequently subjected to pressure developed by compressed gaseous or vaporous fluids for building up a pressure inside the shells to equal the pressure surrounding the shells whereafter the pressure surrounding the shells is instantaneously released causing the pressures built up internally of the shells forcibly to press the kernels against the weakest or natural cleavage region of the shells where a tear or slit is produced through which the kernels are ejected from the shells and also from the epidermis or testae which remains attached to the shells.  The preliminary softening treatment may be (a) by soaking in water to allow it to penetrate the shell only or (b) subjecting to forced draught or circulation of hot gases, e.g. air or steam under predetermined pressure, or (c) immersing in or subjecting to a bath of hot shell liquid obtained from the shells to obtain the largest percentage possible of shell liquid extraction after which the nuts may be submitted to treatments (a) or (b) for softening the shell.  After pretreatment the nuts or seeds are placed in a pressure chamber and treated by (d) pumping air in until the desired pressure is obtained and then forcing compressed air into the interior of the nut or seed and when the interior pressure is equal to the exterior pressure and equal to the pressure required to eject the kernels, the exterior pressure is instantaneously released and the kernels are ejected and separated from the shells and epidermis simultaneously, or (e) by introducing steam and/or hot air into a pressure chamber until the required pressure and temperature are obtained and after sufficient time has elapsed for the internal pressure to equal that of the external pressure and the pressure required for the ejection of the kernels from the shells and epidermis is attained, instantaneous release of the external pressure is effected, care being

Filed: 1946-07-18
Abstract: 640,505. Two-stroke engines. RIISE, S.S. July 18, 1946, No. 21561. Convention date, June 23, 1945. [Classes 7(ii) and 7(vi)] In a two-stroke engine exhaust from the cylinder takes place in two stages, high pressure exhaust first passing to atmosphere through non-return means either directly or through a turbine, and low pressure exhaust subsequently passing to a receiver having a capacity 1.5 that of the cylinder and subject to the continuous suction of a pump driven by an exhaustactuated turbine, the engine crank-shaft or a separate source of power. Charge is thus drawn into the cylinder, the arrangement being such that the amount of charge flowing into the cylinder causes the pressure therein to rise to at least atmospheric pressure. As shown, high pressure exhaust passes through a passage 8 from a cylinder 5 when the exhaust valve 6 is lifted and subsequently a sleeve valve 7 attached to the valve uncovers a low pressure passage 9. Alternatively passages below the piston crown register with ports in the cylinder walls. The high pressure exhaust passage is dimensioned so that its resistance prevents air from escaping during the compression stroke. The Specification as open to inspection under Sect. 91 comprises also an ejector through which the high pressure exhaust passes to produce suction in the receiver. This subject-matter does not appear in the Specification as accepted.

Title: A process for eliminating sulphur oxides from combustion exhaust gases
IPC: B01D53/50
Filed: 1966-05-18
Abstract: <PICT:1098557/C1/1> In a treatment of combustion exhaust gases to remove their sulphur oxide content, wherein active carbon is submitted to a cyclic treatment of three stages, viz.: an absorption stage when sulphur oxides are absorbed from the gas stream by the active carbon for a given time and are oxidized by oxygen also present in the gas stream, a washing stage when the active carbon is washed with water to produce sulphuric acid from the sulphur oxides absorbed thereon, and a drying stage; the exhaust gas stream to be treated is divided into two parts, the first part being always utilized in the above-mentioned drying stage, in which its heat content is used to achieve the necessary drying and this part of the stream loses some of its sulphur oxide content to the dried carbon and suffers a lowering of temperature, so that when it is remixed with the second part of the gas stream it acts to lower the temperature of the stream to a value suitable to achieve maximum removal of the sulphur oxide content when the whole stream is passed through the active carbon in the absorbing step.  Preferably the three stages of the process are carried out simultaneously a single bed of activated carbon being divided into a plurality of portions which can selectively be submitted to the stages of absorption washing and drying.  In a preferred apparatus (Fig. 1), the bed 6 is circular and divided radially into six sections, three of which are undergoing absorption, one washing and two drying.  The bed is situate in a container having inlets 2, 3 and outlets 2a, 3a concentrically situated above and below the bed, said parts being fitted with valve means 9 so that the sections of the bed may be either completely cut off from or connected respectively to the appropriate inlets and outlets.  The inlet 3 carries that stream of gas which achieves the drying step and is returned to the other stream before it enters inlet 2 for the absorbing stage. Treated gases are vented through pipe 12 to the atmosphere.
