Title: Improved method of and apparatus for the continuous drying and roasting of cocoa beans and the like
IPC: A23N12/08
Filed: 1929-08-14
Abstract: 330,826. Steely, D. G., and Blake, F. W. Aug. 14, 1929. Roasting granular &c. materials.- Cocoa beans and the like are dried and roasted in a continuous stream by passing them in a hollow column down a long vertical stack, heated gases being caused to pass alternately in opposite directions through the sides of the hollow column from one end to the other : the beans are withdrawn from the lower end of the stack in a broad and thin horizontal sheet. The beans occupy the space between the innermost tube 14 and the intermediate tube 12 of the vertical stack which has an outer casing 10. They are fed by a conveyer 24 through an opening 20 in the side of the stack into a hopper 18 formed at the top of the intermediate tube and gradually pass downwards through the stack. The inner tube 14, which is perforated and formed in sections, is provided with conical partitions 34 having openings 36 normally closed by tampons 38 arranged on a chain 40. By pulling the chain the tampons are lifted and any dust &c. that collects in the compartments can fall to the bottom of the stack. The intermediate tube 12 also is perforated and composed of sections, each section being formed of two semi-cylindrical flanged members bolted to each other. The outer casing is formed of semi-cylindrical flanged members bolted together, and diaphragm plates 50 extend between the outer shell and the intermediate tube, these diaphragms being staggered relatively to the partitions 34 so that the roasting and drying gases, which are introduced by a pipe 52 at the base of the stack, are forced to travel continuously between the inner and outer tubes across the column of descending beans. Dust collecting in the outer casing is withdrawn through openings 58 at the bottom of each section, said openings being normally closed by flexible bands 60. The lower end of the intermediate tube is extended below the outer tube and is provided with a conical discharge nozzle 66 that has an adjustable long and narrow discharge opening through which the beans are adapted to be discharged in a broad and thin horizontal sheet on to a conveyer 68. The hot roasted beans are cooled by cool air drawn through the beans on the belt by a suction pipe 80.

Title: An improved system for automatically obtaining a desired ratio between two or more quantities
IPC: G05B13/02
Filed: 1958-08-05
Abstract: 901,641. Automatic control systems. SARNOFF, S. J. Aug. 5, 1958 [Aug. 8, 1957], No 25002/58. Class 38 (4). In a control system for a plant or process having a plurality of operating variables which are a function of the adjustment of a plurality of regulating elements, the ratio of two electrical signals corresponding to the values of two of the variables controls the regulating elements in succession to obtain a desired ratio. In an aircraft, transducers 11, 10, Fig. 2, respectively produce voltages, dependent on airspeed and rate of flow of fuel, arranged in a bridge circuit self-balanced by a motor 8 so that the position of a coupled potentiometer 24 represents miles per gallon. Potentiometer 24 is arranged in a second bridge circuit, the output of which represents deviation of m.p.g. from a desired value selected by the setting of a further potentiometer 16. This error signal is applied through a continuously-driven selector switch 17 to controllers 1-5 in succession so that variables such as throttle setting, propeller pitch, carburetter mixture, and supercharger pressure, according to which of switches 35-39 are closed, are adjusted in such sense as to correct the m.p.g. figure. Networks 40 may introduce a rate component of control. If it is desired that m.p.g. shall be a maximum, potentiometer 16 is set to an extreme position and networks 40 arranged to transmit rate components only. Systems in which control signals are a function of more than two variables and/or groups of correctors are controlled by groups of detectors are referred to. Application to obtaining optimum conditions in helicopter stabilization, chemical plant, steam power plant, paper manufacture, machine tool finish and air conditioning is referred to.

Filed: 1963-06-26
Abstract: 1,023,601. Photocopying apparatus. LAWES BROS Ltd. June 23, 1964 [June 26, 1963], No. 25414/63. Heading G2A. In a photocopying machine in which the original and copy sheet are conveyed together in contact round a translucent cylinder 1 housing a light source 2 by a number of separate endless bands 7 spaced along the length of the cylinder, the areas of the copy sheet registering with the bands is given a different degree of exposure from those areas registering with the spaces between the bands. As shown, this is effected by a comb plate 5 fixed to an air-duct 4 which is located within the cylinder 1, and which also carries a reflector 3. The comb plate has a castellated edge with cutaway'slots 6 corresponding to the spaces between the bands 7. Thus as the sheets are carried round the exposure cylinder, those areas passing below the slots 6 will receive more exposure than the remaining areas. It is stated that this differential exposure tends to eliminate the streakiness sometimes obtained with separate conveyor belts.

Abstract: 989,488. Thermo-aluminic and like processes; welding by fusion. YAWATA IRON & STEEL CO. Ltd. July 14, 1961 [July 22, 1960], No. 25690/61. Headings B3R and B3V. In a fusion welding process a thermo-aluminic agent positioned in a joint or cavity to be welded is ignited by an arc passed between a wire or rod electrode 2 and the work, to produce a molten weld deposit 9 covered by molten flux 5 into which the end of the electrode 2 dips as welding proceeds upwardly. The thermo-aluminic agent is added continuously or intermittently and the welding heat is derived from the chemical reaction and the resistance heating of the welding current. A carbon or fusible metal electrode is used and filter metal, e.g. alloying metals, may be added to the agent or the melt. In this way, four members 1, Fig. 1, may be welded to form a cross. Two vertical members may be welded using vertically moving water-cooled steel melt retaining plates with grooves in their upper ends to drain surplus flux. The process can be used for filling a cavity in which case a melt retaining sleeve 7, Fig. 4, is used. Up to three consumable electrodes may be used simultaneously. The electrodes may be oscillated transversely.
