Title: Cyclonic fluid separators
Inventor: MORNS JAMES GREENWELL
IPC: B04C5/103
Filed: 1968-07-05
Abstract: 1,261,906. Centrifugal separators. CLARKE CHAPMAN & JOHN THOMPSON Ltd. 4 July, 1969 [5 July, 1968], No. 32232/68. Addition to 937,549. Heading B2P. In a cyclone separator of the kind described in the parent Specification, but in which the angular extent of the rectangular entry duct 2 is not necessarily 180‹, there is located within the cylindrical casing 1 and at a distance below the lower termination of the duct 2 an inner duct tube 10 and a bottom plate 11 spaced from the tube 10, the tube and the plate each having an annular gap between it and the wall of the cylindrical casing. The tube 10 and the plate 11 are secured to the casing by straps 12. 13. The tube 10 is frustoconical and has a chamfered edge 14, Fig. 3, at its upper larger end. When treating wet steam, the tube 10 forms a restriction in the path of the descending water vortex which is also supported by the plate 11 independently of the level of water outside the casing. These features provide less tendency for the layer of water in the centre of the plate 11 to become too thin when there is a low water level outside the casing so that re-entrainment of steam is reduced. The gap between the chamfered edge 14 of the tube 10 and the casing allows only steam-free water to drain away so that surplus water falling inside the tube 10 has a reduced velocity when it flows through the gap between the plate 11 and the lower edge of the tube 10 thereby reducing re-entrainment of steam. Re-entrainment may be further reduced by providing a plate 16, Fig. 4, below the bottom edge of the casing, the gap between the plate and the casing being adjustable by means of a threaded attachment 17-19. A number of separators may be mounted in a battery as illustrated in Fig. 6 or Figs. 7 and 8 of the parent specification.

Abstract: 383,433. Changing frequency. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Salzberg, B. ; Rocky Point, Long Island, New York, U.S.A.) Nov. 26, 1931, No. 32832. Convention date, Dec. 26, 1930. [Class 38 (ii).] An electronic frequency multiplier suitable for use at very high frequencies comprises electrostatic means for cyclically deflecting an electron stream so that it strikes in turn a number of anodes connected alternately to opposite sides of a tuned output circuit. As shown in Fig. 1, the input is generated by a short-wave oscillator 54 and is applied through feeders 56, 60, 62 to two pairs of plates 20, 22 and 24, 26 set orthogonally in the tube 2. The electron stream from the cathode 4 is thus caused to sweep out a conical path and to impinge in succession on a series of conductive targets 30 arranged on an insulating, ring 18. The targets are alternately connected to opposite sides of an output circuit 36, tuned to the multiple frequency. If the deflecting plates 20, 22 are situated the same distance along the tube as the plates 24, 26, they are energized in phase quadrature, but if the pairs of plates are displaced as shown, their relative phase is suitably adjusted, having regard to the time of passage of the electrons, by means of U-shaped slides 58 in the line 56. The electron stream is concentrated bv a negatively-charged annular screen 8 and a hollow cylindrical anode 10 positively charged by a source 12 through a resistance 14. The targets may be arranged in an elliptical or other curved path, and when a single pair of deflecting plates is employed, the targets may be in a straight line and so spaced that equal time intervals elapse between contacts with successive targets, Fig. 2 (not shown).

Title: A method of producing an instant cocoa
IPC: A23G1/56
Filed: 1960-09-27
Abstract: "Instant" cocoa is produced by subjecting cocoa powder, mixed if desired with sugar and other ingredients, to the action of steam under pressure to produce a cooked cocoa powder having a water content between 8 and 20% and then granulating the powder. In Example 1, 1 kg. commercial cocoa powder is heated in an autoclave, with a double bottom which contains sufficient water to keep the atmosphere saturated with steam, until the pressure rises to 1.5 kg. per square inch which is maintained for about 3 minutes.  The pressure is then lowered and the treated powder is granulated by means of a 0.5 mm. sieve and allowed to dry. Alternatively, Example 2, instead of treating for a given time, the cocoa powder can be treated with a measured amount of water turned into steam under pressure.  The powder may be agitated during treatment.  A mixture of equal parts of cocoa powder and powdered crystallized sugar may be treated as in Example 1 to produce a sweetened instant cocoa, care being taken not to let any condensate reach the mixture.  Similar treatment may be given to a mixture of the following powders: 30 parts cocoa, 55 parts sugar, 6 parts milk, 7 parts malt extract, 1 part lecithin, 0.5 part calcium phosphate and 0.5 part magnesium phosphate.
