Abstract: 444,290. Centrifugal gas -separators. GOERIG & CO. AKT.-GES., 25, Hafenstrasse, Mannheim, Germany.-(Assignees of Haken, K. von and Kulisitsch, S. von; 176, Kurf³rstendamm, Berlin) Aug. 3, 1935, No. 22074. Convention date, Aug. 7, 1934. [Class 23] [See also Group XII] Gas is extracted from mixtures of dust and gas during the progress of chemical and thermal processes, by withdrawal through annular louvres where the flow in a reaction vessel changes its direction, while the remainder of the mixture, richer in dust, passes onwards. Suitableapparatus for the treatment of coal dust in the recovery of benzine is shown in Fig. 1. The cyclone chamber 5 is supplied with the pre-heated mixture through the inlet 1 and the socket 2 ; the latter has tangential passages 3 which impart a whirling motion to the entering gas. In addition to this whirling the gases also rotate as shown by the arrows a, b, and gas passes through the annular louvres 4 to the outlet 7. The remainder of the gas with the dust passes downwards to the outlet, and the lower part of the chamber 5 receives a scavenging gas through the jacket 8 and tangential slots 9 to prevent caked dust from adhering to the walls. The cyclone chambers and reaction chamber 12, Fig. 4, are surrounded by a heat insulating shell 10. The top section 5<1> serves to draw off oxygen from the dust-laden gas supplied through the inlet 11. The scavenging and reaction gases are supplied through the inlets 11<1> ... 11<1111>. The second section 5<11> serves for preheating the dust with scavenging gas and has tangential entry slots through its whole length. The reaction column 12 has a series of staggered tangential slots, and a partition 14 in the shell 10 enables the mixture to be cooled before reaching the discharge outlet 13.

Filed: 1952-09-04
Abstract: 735,444. Capping bottles. FORDS (FINSBURY), Ltd. Sept. 9, 1953 [Sept. 4, 1952], No. 22269/52. Class 125 (2). In apparatus for spinning the flange of a bottle cap onto the bottle neck, the spinning head is quickly detachable from its driving member without the use of tools. A driving motor 53 through a belt 54 and gearing 55, 34 rotates a driving collar 26 (the driving member) which has an upper tubular part 28 keyed to the gear 34. A rod 43 is rotatably mounted within part 28 and has an upper peg 47 projecting into a collar 48 loaded by a spring 49. Suspended from rod 43 is a sleeve 14 in which a rod 12 is suspended by a pin and slot connection 39, 40. The bottom of rod 12 carries a plate 12a engaging the cap 20. According to the Provisional Specification, the plate 12a may be cup-shaped and lined with rubber to fit the cap. Surrounding the sleeve 14 is a collar 13 in which are pivoted arms 17 provided at their lower ends with spinning rollers 19, urged outwardly by compression springs 17a and having upper rollers 23 carried on pins 23a the ends of which rest on lips 25 formed on driving collar 26. When the rollers 23 are raised, they run in grooves 24 in collar 26 to urge the rollers 19 inwards. A spring 41 acts between the collar 13 and a flange 14a on sleeve 14. To remove the spinning head, the carrying plate 29 is swung to one side, the rollers 19 are grasped by the hand and moved inwards thus lifting pins 23a off lips 25 and then the collar 13 with the arms 17, the sleeve 14 and rod 43 can be pulled out. In operation, the driving collar 26 is rotating continuously and a bottle 22 on support 2 is raised by operating a handle 6. It first contacts plate 12a which is raised until it abuts flange 14a whereupon spring 41 is compressed. The cap meanwhile is centred by rollers 27.. When pin 39 reaches the top of slot 40, the collar 13 and rod 43 are raised against spring 49 so that rollers 23 ride up the grooves 24 to cause rollers 19 to engage the cap flange. In a modification, Fig. 2, bottles are fed by conveyer 60 into a holder 61 having three bottle supports 75 and rotated by shaft 63. The supports 75 ride on a fixed cam 77 to present the bottles to sealing heads 11 constructed as described above. These heads are suspended from a shell 64 rotated through dowel rods 74 from the holder 61. A fixed shaft 66 has a stationary gear 72 which causes rotation of gears 71, 70 as the shell 64 rotates. Gear 70 drives a gear 67 loose on the shaft 66 and carrying a shell 65 forming with a geared annulus which drives the gears 34 of the sealing heads. The sealing heads are adjustable in height by a handwheel 83. When a nut 86 is removed, the carrying arm can be raised to disengage the rods 74 from the holder 61 and then swung aside. The spinning heads can then be unhooked from the lips 25 on the driving collars 26.
