Title: Improvements relating to apparatus for conveying material in bulk
IPC: B65G25/00
Filed: 1947-09-30
Abstract: 642,426. Reciprocating conveyers. SMIDTH & CO. AKTIESELSKAB, F. L. Sept. 30, 1947, No. 26425. Convention date, Sept. 30, 1946. [Class 78 (i)] An apparatus for conveying material in bulk over a support 1 in which the support is stationary and the conveyer members 3 reciprocate over it, is characterized in that the conveyer members slide over and are pressed into contact with the support, the conveyer members being wedge-shaped so that they push the material on their forward stroke and slide through it on their backward stroke. As shown, cement clinker falls from shoot 32 on to support 1 and is urged forward by reciprocating members 3 and is discharged at 35. Conveyer members 3 slide over portion 2 of surface 1 and are resiliently secured to beams 15 and 18 and 19 by means of bolts 10, springs 14 and nuts 13; and are reciprocated by driving- arms 24 which have a roller 25 which engage with lugs 23 fixed on beam 19. The conveyer members are formed with holes so that air entering at 37 passes up through these holes in the conveyer members and cools the clinker, the air being divided by partition 36 to allow the hotter portion to escape at 33 to the cement kiln and the cooler portion to go waste at 34. Air also escapes through the holes shown in surface 1 and additionally is introduced at 38 to escape through holes in support 39. The clinker as it falls down shoot 32 may be spread by distributing units, not shown, so as to divide into several flows and spread over the surface evenly.

Filed: 1921-10-10
Abstract: 170,015. American Radio & Research Corporation, (Assignees of Smith, C. G.). Oct. 8, 1920, [Convention date]. Vacuum tubes.-In a rectifying tube having electrodes spaced apart at a distance approximating to the mean free path of electrons in the gas contained in the bulb, the paths of the electrons are influence by means, such as a magnetic field; so as to permit conduction in one direction only between the electrodes. It is stated that no discharge occurs without the magnetic field, owing to the close spacing of the electrodes, but that the magnetic field increases the mean path of the electrons sufficiently to produce ionization by collision. As shown, the electrodes 12, 13, which may be of molybdenum, are of concentric shape, and a magnetic field parallel to the axis of the electrodes, is produced by a permanent magnet 15. The electrode 13 is mounted in grooves in cylinders 17, 18 of magnetic material, secured together by a sleeve 19 of non-magnetic material, and spaced from the bulb by washers 35. The electrode 12 is fused or welded between iron rods 20, 21 which are secured by a nut 30 on one rod 21, the end 22 of the other rod being enlarged. The rods are insulated by glass &c. cylinders 25 spaced by flanged collars 28 of copper or other non-magnetic material. The ends 31 of the cylinders 17, 18 are counterbored to provide a long insulation path. Slots 14 in the sleeve 19 allow escape of heat from the electrodes. Specification 168,882 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of the tube as an amplifier or oscillation generator.

Abstract: The Provisional Specification describes the preparation of aluminium silicate comprising mixing solutions of sodium hydroxide and sodium silicate in amounts such that the silicate conforms to Na2SiO3 and adding the mixture to a solution of aluminium nitrate in amounts such that the ratio of Al2O3 to SiO2 is 1 : 1.  The compound is a catalyst for the conversion of levulinic acid or its esters to methyl vinyl ketone (see Group IV (b)).ALSO:Methyl vinyl ketone is produced by heating alpha or beta angelica lactone or levulinic acid or an ester thereof in the vapour phase at a temperature of from 450 DEG  to 650 DEG  C.  The reaction may be carried out in a vessel packed with filling bodies such as silica chips or pumice, in the presence of a dehydrating or cracking catalyst such as aluminium silicate or in an unpacked vessel.  If desired, angelica lactone may be prepared in situ and the process then carried out in several stages.  In examples, the ketone is prepared (1) by passing alpha angelica lactone or levulinic acid over silica chips at 570 DEG  C.; (2) by passing levulinic acid over basic aluminium phosphate at 350 DEG -360 DEG  C. and then passing the exit vapours over heated silica chips as in (1). Specification 453,518 is referred to.  The processes described in the Provisional Specifications are not limited to the use of the above temperatures; both Specifications describe the preparation of the abovementioned aluminium silicate comprising heating a mixed solution of sodium hydroxide and sodium silicate with a solution of aluminium nitrate (see Group III).

Abstract: 1,137,880. Crimping yarns. TURBO MACHINE CO. 17 June, 1966 [17 June, 1965], No. 27067/66. Headings DID and D1F. In a process of crimping yarn by twisting two yarns together, heat-setting the yarns, and then separating the twist-set yarns, each separated yarn 20 or 21 is passed over a guide 74 or 75, with the guides being laterally movable should the tension in the separated yarns be unequal. The movement of the guides causes the yarn of higher tension to move towards the smaller end of its pair of conical draw rolls 16, 18 or 17, 19 and the yarn of lower tension to move towards the larger end of its pair of draw rolls. In the embodiment shown guides 74, 75 are formed by spools mounted on the ends of arms 72, 73 of a V- shaped spring-tensioned wire member 70 mounted on stud 58 which is rotatably supported. Arms 74, 75 are adjustably urged together by collar 76. Yarn guides 36, 37 maintain the separation point S substantially constant. Conical rolls 16, 17 have a rubber surface, are mounted on a common drive shaft and have rolls 18, 19 pressed against them by air cylinders against the force of removal springs. The separated yarns 20, 21 are wound on packages driven by a common drive roller. Excessive movement of wire member 70 is prevented by U-shaped guide 77, while mercury switches 90, 81 stop the machine if the member moves more than a set amount. In modifications guides 74, 75 are mounted on vertical end portions of generally horizontal arms adjustably secured together and pivotable about a vertical axis, or guides 74, 75 and 36, 37 are formed by bars mounted on a plate pivotable about a horizontal axis, or guides 74 and 36, and 75 and 37 may be formed by a single pair of guide bars mounted on a plate pivotal about a horizontal axis with conical rolls 16, 17 being mounted on parallel shafts on either side of the guide bar.
