Abstract: <PICT:0920909/III/1> <PICT:0920909/III/2> The apparatus of the parent Specification is modified by the provision of a gridlike agitating member having a small cross-sectional area compared with the total cross-sectional area spanned thereby, which corresponds to the internal cross-section of the aerating vessel, allowance being made for the free up-and-down movement of the agitator within the vessel, and means whereby such movement may be brought about.  The agitator 8 may comprise a frame 9 connected by struts 11 to a central rod 10 which may be used for lifting and lowering the agitator, with or without additional rotation or swivelling.  Additional transverse members 12 may be provided on the frame 9, which, with the members attached thereto, has a downward taper.  As shown in Fig. 1, the rod 10 passes through the bottmo of an aerating box 1, and may be raised and lowered with respect thereto by an hydraulic or pneumatic cylinder 13.  The aerating cylinder itself may be raised and lowered by one or more hydraulic or pneumatic devices 7 with respect to the funnel 4, 5 on which a pre-heated or adhesive coated pipe 6, to be coated, is mounted.  In operation, the agitator is raised and lowered through the particulate coating material contained in the aerating vessel 1, after which the latter is raised to introduce the coating material into the pipe p  6, and lowered after an appropriate interval.

Title: Improvements in and relating to processes for the treatment of soya beans and the products obtained thereby
IPC: A23L11/00
Filed: 1935-02-07
Abstract: Shelled soya beans are steeped from 30 to 60 minutes in warm water until they swell slightly and their moisture content amounts to about 20 per cent.  They are then dried on or between heated rollers after preferably having been squeezed to a thickness of one millimetre by passage between rollers.  The rate at which the beans are passed through the heated rollers is such that the bean flakes when cool have a moisture content of not more than 6 per cent.  The flakes are subjected to the action of a strong current of air and may be worked up into meal or flour.  The process may be carried out under reduced pressure.  The beans may be pressed cool to express approximately half their content of fats. Materials such as rice, potatoes, cereals, e.g. wheat, rye, barley, oats, &c. may be steeped with the beans and passed through the rollers to form a mixed food.ALSO:Shelled soya beans are steeped for from thirty to sixty minutes in warm water until they swell slightly and their moisture content amounts to about 20 per cent.

Title: Ram jet fuel system
Inventor: ACKLAND DOUGLAS EDWARD
IPC: F02K7/10
Filed: 1968-01-25
Abstract: 1,235,354. Ram-jet engine fuel systems. ROLLS-ROYCE Ltd. Jan. 17, 1969 [Jan. 25, 1968] No. 4061/68. Heading F1J. A fuel control system for a ram jet engine comprises a turbine driven by a ram air, the turbine driving a fuel pump which supplies fuel to the engine combustion chamber, there being a variable restriction in the outlet line from the fuel pump also a fixed restriction downstream thereof, the area of the variable restriction being controlled by the difference in pressure between ram air taken from the engine and the fuel downstream of the variable restriction. The turbine 10 shown in Fig. 2 is supplied with ram air through duct 11 and drives fuel pump 12 which has an inlet 14 and an outlet 16 which communicates with an annular chamber 21 formed around a cylindrical chamber 20. A cylindrical sleeve 22 having a closed end 24 and formed with orifices 23 is axially movable within the cylindrical chamber 20, the orifices 23 co-operating with the edge of the annular chamber 21 to define a variable restriction through which fuel may flow from the pump outlet 16 to the duct 17 which communicates through a fixed restriction 18 with the fuel burners 19 which are mounted in the engine combustion chamber. A chamber 26 is formed at the right-hand side of the end wall 24 of the cylindrical sleeve 22 and the ram air duct 11 communicates therewith so that the sleeve 22 is urged to the left by ram air pressure plus the force of the spring 27, and to the right by fuel pressure. Increase in ram air pressure will thus cause the sleeve 22 to move to the left so reducing the area of the variable orifice 23 and so the fuel flow is reduced. As a result of the increase in ram air pressure the turbine will increase in speed and so the output of the pump is increased - the sleeve 22 will thus oscillate until the pressure conditions are balanced.

Patent GB-975775-A (GB)
Title: Ammonia synthesis gas process
IPC: C01B3/02
Filed: 1962-02-06
Abstract: Ammonia synthesis gas is produced from hydrocarbons by successive steps of primary reforming with steam, secondary reforming with air, shift conversion and removal of oxides of carbon, wherein the steam to carbon ratio of the primary step is 4.0 to 8.0 and the pressure of the secondary reforming step is 270-650 p.s.i.a.  Thus an embodiment discloses, desulphurized compressed gaseous hydrocarbon, e.g. natural gas, mixed with steam and preheated to 600 DEG  F. by the combustion gases used to heat the primary reforming step.  The mixture of gas and steam passes over nickel bearing catalysts in the externally fired primary reformer furnace and leaves at 1350 DEG -1650 DEG  F. at 50-200 p.s.i.a.  The combustion gases from the primary reformer may also be used to generate high pressure steam by burning with additional fuel in a waste heat boiler.  The reformed gases are mixed with compressed air at 25 p.s.i.a., preheated, if desired, to 300-1250 DEG  F. and pass to the secondary reformer which contains a nickel bearing catalyst and leave at 1650-2000 DEG  F. The exhaust gases are quenched with steam and/or water, to 1100-1200 DEG  F. if the gas then passes through a waste heat boiler, or to 550-700 DEG F. if the gas passes directly to the shift converter.  The shift converter contains a plurality of catalyst beds with intermediate injection of steam, water or both to maintain the temperature in the range of 550-700 DEG  F.  The crude synthesis gas and surplus steam from the converter are passed through another waste heat boiler and also used to regenerate the solutions, e.g. aqueous monoethanolamine, potassium carbonate or ammoniacal copper liquor, used to remove CO and CO2 from the crude synthesis gas.  The gas stream passes through a separator to remove steam, on to a cooling and purification plant where CO and CO2 are removed and after compression passes on to the ammonia synthesis plant.  A particular embodiment of the invention and the optimum conditions for reaction are disclosed in Figs. 1 and 2 (not shown).

Abstract: 631,165. Jet-propelled aircraft screw propellers. MAGILL, H. L. Feb. 23, 1945, No. 4653. Convention date, Dec. 30, 1943. [Classes 4 and 114] An aircraft is provided with one or more screw propellers driven by reaction jets near the blade tips, the blades being of variable pitch and capable of being adjusted to such a setting that the thrust from the propeller is primarily one of direct reaction from the jets at the blade tips. The blade pitch may be controlled automatically in accordance with the height of the aircraft, so that the propeller rotates at substantially constant speed. In the form shown in Figs. 1 and 5 gases are delivered to nozzles 24 near the tips of the blades 15, from a combustion chamber 19, as described in Specification 631,194, [Group XII]. Pitch adjustment of the blades is effected by bevel gearing 226, 227 and a rotary threaded sleeve 223 operated by an axially movable member 223b actuated through worm gearing 220k, 220l and an arm 220e by an electric motor 220m. The latter may be controlled by a hand lever 2f, or automatically by a centrifugal governor 6 to maintain a constant speed of rotation. The speed of the propeller may also be varied by controlling the supply of gas from the combustion chamber 19. Fig. 1 shows an aircraft provided with a single screw propeller. fixed reaction nozzles 25. 26 at the trailing edges of the wings, and a universally-mounted nozzle 29 at the tail of the machine. The propulsive gases are supplied from combustion chambers 27, 28, 31 similar to the chamber 19. At high altitudes the thrust of the jets from the nozzles may be augmented by adjusting the blades 15 of the propeller to a pitch setting of 90 degrees, so that the blade-tip jets are directed rearwardly. A helicopter comprising contrarotating coaxial lifting rotors 396, 397 and a tail rotor 408 of construction similar to the propeller 15 is shown in Fig. 28, the gases being supplied by combustion chambers 393, 419. The lifting rotors are carried by a universal joint 392 so as to be tiltable in any direction, while the tail rotor is capable of movement about a vertical axis for effecting control in yaw. The Specification as open to inspection under Sect. 91 comprises the subject-matter of divisional Specification 631,194. This subjectmatter does not appear in the Specification as accepted.
