Title: Process and apparatus for mixing flowable materials
IPC: B01F25/90
Filed: 1947-06-20
Abstract: 643,470. Centrifugal mixing apparatus. SAFETY CAR HEATING & LIGHTING CO., Inc. June 20, 1947, No. 16298. Convention date, Dec. 26, 1946. [Classes 23 and 86] A continuous mixing apparatus comprises means for feeding in predetermined ratios the constituents of flowable materials, such as flour, paints, insecticides &c. into a turbulent centrifugal mixing zone, particularly suitable for mixing small percentages of minor constituents with larger quantities of major constituents. A controlled stream of the major constituents of a product is fed from a bin 2 to a screw conveyer 12 into which controlled amounts of the minor constituents are also fed, in a larger proportion than required in the final product, by screw conveyers 18, 20, 22, and 24 withdrawing materials from the bins 4, 6, 8 and 10 respectively. The constituents are fed from the bins by motors M at rates corresponding to the ratio of the constituents required in the final product. A uniform stream of the product is fed through a spout 26 to the treatment zone of a centrifugal mixing machine 28, of the type described in Specification 563,052, comprising a lower annular plate 36 extending outwardly from the base of a frustro-conical hub portion 34 and a top annular plate 40 mounted on vertical and concentrically-spaced impactors 38 to form a treatment zone between the plates 38, 40. The intermediate product and the correct amount of the major constituent are withdrawn from the bins 46, 2 by screw conveyors 48, 52 respectively and fed into a similar mixing machine 50 so that the final product received in the bin 62 contains the constituents in the ratio required. The final product may be produced by several intermediate stages followed by a final mixing operation. In a modification. star feeders regulate the amounts of the different constituents which fall on to a constant speed endless belt which deposits the accumulated stream into one, or more, centrifugal machines. The Specification as open to inspection under Sect. 91 comprises also a drying arrangement in which moist flour in a bin 100, Fig. 3 (Cancelled), is fed at a constant rate by a star feeder 102 through a spout 103 to a centrifugal machine 104. At the same time, a relatively large stream of air is blown by a fan 106 through a heating coil 108 and a spout 110 into the machine 104 to treat the flow. The latter is then fed into a separating bin 112 where substantially all of the air separates from the flour and is discharged through a cyclone separator 114 by a fan 116. The flour from the bin 113 and the separator 114 is discharged to a storage bin 118 through star feeders 120 and 122 respectively. A further arrangement comprises similar means for bleaching flow. This subject-matter does not appear in the Specification as accepted.

Vacuum engines. - A fluid-actuated wind-screen cleaner is provided on the motor casing with a valve for the purpose of confining the fluid pressure to one side only of the piston so as to maintain the cleaning element out of the field of vision when not in use. In the construction shown in Figs. 1, 4, and 5, the motor comprises a cylinder 3 provided with pistons 7 connected by a member 8 with openings 9 for engaging a toothed segment 10. This segment is secured to a shaft 4 supporting the cleaner element. The cylinder is provided with a main suction passage 15 and with passages 13 adapted to communicate with the spaces at the ends of the cylinder. A cup-shaped valve 16 is adapted to cover the end of the passage 15 and the end of one or other of the passages 13. The valve is carried by a pivoted member 17 connected by a spring 22 to a slide 23. As the pistons 7 are actuated they contact with the slide 23 thereby shifting the valve 16 to bring the opposite ends of the cylinder 3 alternately into communication with the source of suction. At one end of the cylinder there is formed a valve chamber 27 screw-threaded to receive a control valve 28 which is formed with a conical portion 31 and with a reduced portion 32. Passages 67, 35 lead from the chamber 27 to the source of suction and the adjacent end of the cylinder, respectively. The chamber is also adapted to communicate by a flexible pipe 34 with the adjacent passage 13. When the cleaner is in use the passage 15 is open and the port 67 closed. To stop the motor the valve is screwed into the chamber 27 so that the passage 15 is closed, as shown, and suction is applied to one end only of the cylinder 3 by way of the passages 35 and 67, thereby causing the cleaner to remain in the raised position. In the construction shown in Figs. 9, 10 and 14, the reciprocating pistons 37 are adapted to actuate valves 43, 44, through the medium of a bar 51, pivoted yokes 49, 46, and a spring 50. The valve 43 brings the ends of the cylinder 36 into communication with the source of suction and the valve 44 allows the ends to be opened to the atmosphere. The cylinder 36 is provided with a hollow valve 57 with openings 61, 62, 63. The opening 61 is always in communication with the source of suction. When the cleaner is in use the opening 62 registers with a passage leading to the space around the stem of the valve 43. To stop the motor the valve is turned in its seating thereby closing the opening 62 and bringing the aperture 63 into registration with a passage 64 leading to one end of the cylinder, so that the cleaner is brought to, and maintained in, the horizontal position. Specification 249,114 [Class 135, Valves &c.], is referred to.

Filed: 1940-11-22
Abstract: 546,666. Food preparations. BRITISH ARKADY CO., Ltd., FORD, W. P., and EGERTON, W. E. Nov. 22, 1940, No. 16792. [Class 49] A golden brown or yellow crust colour is imparted to baked unfermented goods such as scones, cakes, biscuits, pastries and pies by incorporating in the dough mix, prior to baking, yeast solids in the proportion of 0.01 to 2 per cent. of the total weight of the mix (including water). Also may be added a substance containing a large proportion of watersoluble protein, such as skim milk powder or soya bean flour; this water-soluble protein assists in tne caramelisation of sugars produced by the yeast during baking, which causes the development of the golden brown &c. colour. The yeast may be distillers', bakers' or brewers'. If a dried yeast preparation is used, it should be soaked in water before addition to the mix. To neutralise the effect of the yeast on the crumb colour, acid or acid salts may be added-e.g. lactic acid, citric acid, acid calcium phosphate, potassium hydrogen tartrate or sodium bisulphate. Specification 484,616 is referred to.

Abstract: 958,644. Cable and wire couplings. AMP Inc. April 30, 1963 [May 9, 1962], No. 16940/63. Heading H2E. An electrical connector (Fig. 3) for permanent connection to the braided metal sheath 6 of a cable 7, comprises an inner metal ferrule 3 which is crimped about the sheath 6 by applying pressure to an outer metal ferrule 1, the material of the inner ferrule being extrudable and entering the interstices of the sheath, and the outer ferrule being of a material which when shaped under crimping pressure maintains the inner ferrule in its extruded shape subsequent to crimping. The connector may be adapted to receive a pig-tail earthing lead 9 (Fig. 8) in which case the outer ferrule 1 has a bight 2 and can thus receive both the inner ferrule 3 and the bared core 81. When crimping is effected, the outer ferrule 1, which may be of tin-plated copper, is deformed to a roughly circular cross-section (Fig. 4) and clamps the core 8<SP>1</SP> causing the inner ferrule (which may comprise 95% tin, 5% antimony), to extrude into the interstices 11 of sheath 6 (Fig. 7, not shown). If a flat conductor is to be crimped between ferrules 1 and 3, ferrule 1 is of circular cross-section initially. Ferrule 1 may have connection tabs, and may be surrounded by an insulating sleeve. The internal diameter of ferrule 3 may be greater than the external diameter of sheath 7, to allow the connector to be slid along and crimped to any desired bared portion of the braid. A connector for a twocore cable has ferrules of generally oval crosssection (Fig. 8, not shown). U.S.A. Specification 3,010,184 is referred to.
