Filed: 1928-06-29
Abstract: 304,181. Zeller, T. Jan. 16, 1928, [Convention date]. Cocoa manufacture.-In the preparation of fresh cocoa beans the known fermentation process is interrupted at the termination of the alcoholic fermentation and before the beginning of the acetic fermentation. The fermentation is interrupted by the application of heat, a temperature of between 45‹ C. to 70‹ C., and preferably between 55‹ C. to 65‹ C., being maintained for about 24 hours in order to complete the decomposition and loosening of the mucous covering. The beans are then washed, and thereafter dried. A rotary drum f with perforations e and stirrers g for washing the beans is shown. The beans are supplied on a belt conveyer band transferred to a hopper d by a stripper a. The drum is located in a cabinet h with a heating coil k, and the external surface of the drum is' cleaned by a brush o. The shaft n is rotated by gearing. The Specification as open to inspection under Sect. 91 (3) (a) comprises also reference to a single rotatable drum extending through a plurality of casings provided with heating devices, each casing having separate charging and discharging apparatus.

Title: Improved homogeneous nuclear reactors
IPC: G21C1/24
Filed: 1957-06-17
Abstract: 837,848. Nuclear reactors. ESSO RESEARCH & ENGINEERING CO. June 17, 1957 [July 3, 1956], No. 18986/57. Class 39(4). To obtain a high neutron flux in a reactor a homogeneous fissile coolant is circulated rapidly through the core by a plurality of conduits each connecting at either end with the reactor core through a port, the sum of the cross-sectional areas of the ports being at least equal to twice the maximum interior cross sectional area of the core. The reactor shell 50, Fig. 2, is spherical and has four inlet and four outlet ports 52, each pair of ports communicating to form a circuit through a heat exchanger and a pump, the conduit 65 from the outlet port being long enough for delayed neutrons to appear before the heat exchanger is reached. The conduits leading to and from the reactor have a larger cross section than the ports, Fig. 3 (not shown). Instead of passing through ports into a shell, the conduits may converge in the core zone 80, Fig. 5, where a concentration of critical mass is achieved. In this last form, which eliminates " hot-spots ", the conduits are shaped as in Fig. 6, in the region of the core, which may comprise solid or liquid fissile material around the conduits. A central conduit 85 may carry a non-fissile coolant, such as H 2 O, D 2 O or a hydrocarbon. The fuel passes through the core quickly, in from 0À001 to 1 second. The fissile coolant may be an aqueous solution of U 2 SO 4  enriched to 93% U<SP>235</SP> and provision is made for withdrawing and replacing this and for recombining gases of decomposition. The fuel could be a suspension in bismuth and the conduits are of stainless or of carbon steel. The reactor walls are of stainless steel. For control rods cadmium or beryllium steel is used. The reactor may be used for producing power and radioactive isotopes, for testing materials and for effecting chemical reactions such as hydrocarbon conversions. Fluxes in the range 10<SP>15</SP> to 10<SP>17</SP> neutrons/cm.<SP>2</SP>/sec. are mentioned. Secondary coolants for the heat exchangers are air, H 2 , He, H 2 O, D 2 O, Na, Na-K alloy, Pb-Bi alloy, Li, LiC1-KC1 eutectic mixture, Hg, Dow-Therm and so on.

Combustion-product plant. - In apparatus for generating products of combustion for use in an expansion engine or turbine 11, the apparatus comprising a double-ended cylinder 1, a free piston 2 and means for producing explosions at both ends of the cylinder, the piston is operated by the pressure of an incoming compressed charge. As shown, the cylinder is provided at each end with inlet and exhaust valves 3, 4 and a sparking plug 5. Combustible mixture under pressure is supplied from a main pipe 8 through pipes 7, and the main 8 may be connected to the pipes 7 in turn bv a butterfly valve 9 operated concurrently with the movements of the piston 2. The exhaust valves 4 are connected by pipes 10 to the expansion engine or turbine 11. In operation, mixture under pressure admitted to the end a of the cylinder drives the piston 2 to the right, expelling exhaust gases from the end b through the open exhaust valve 4. The left inlet valve 3 then closes, the mixture in the end a is exploded by the plug 5, the left exhaust valve 4 is opened and the exhaust gases escape until the pressure falls to that of the combustible mixture supply. The right inlet valve 3 is then opened, and mixture admitted to the end b drives the piston 2 to the left, expelling the remaining exhaust gases from the end a, whereupon the cycle is repeated. In a modification, the expansion engine 11 is a reciprocating engine, one of the cylinders of which supplies the compressed charge to the pipe 8 on the compression stroke and is supplied with exhaust gases from the cylinder 1 on the expansion stroke. In other forms, the inlet pipe. 8 is replaced by separate inlet pipes for gas and air, and a number of combustion chambers 1 supply a single expansion engine or turbine, the period of low pressure of the exhaust from one such chamber corresponding with that of high pressure of the exhaust from another, in order to maintain a high mean pressure.
