Title: Improvements in centrifugal separators
IPC: B04B5/12
Filed: 1951-02-21
Abstract: 693,999. Centrifugal separators. ALPINE AKT. - GES. EISENGIESSEREI UND MASCHINENFABRIK. Feb. 21, 1951 [Feb. 24, 1950], No. 4210/51. Class 23 [Also in Group XXVI] Coarse material is separated from a fluid in a cyclone separator, the inwardly-flowing liquid or gaseous fluid carrying fine material being discharged axially through one or more apertures in a rotor which forms part of the boundary wall or walls of the casing. Figs. 1, 2, show an inlet 11 for dust-laden air which flows around a casing 1 into which a second stream of air is introduced through a pipe under control of a valve 25. Coarse material is directed by a point 24 into an outlet controlled by a valve 13. The air leaves through annular openings 9, in rotor walls 5, and passes through impeller vanes 4 to outlets 10. Clean air is sucked in through ports 26 which prevents dust passing down to bearings 27 and cleans gaps 28 of dust. Air is also blown inwards through gaps 29 to the separator chamber 6. In Figs. 3 and 4 an inlet 31 leads to a separator chamber bounded by adjustable vanes 36 formed into a flat spiral 34. Coarse material is diverted by an edge 37 into an opening 38 and is discharged, as a plug 46, by a screw conveyer 39 to an outlet 47. The plug acts as a seal against the atmosphere. The part 40, of the chamber extends along a spiral line 41 which is inclined at approximately the average inclination of the vanes. Air, containing fine material, passes through an opening 45 into a rotor 43, having vanes 48, into a spiral casing 49 leading to another separator (not shown). Fresh air 51 flows inwards through gaps 50, and air 52 through vanes 48, which are hollow, to a gap between the rotor periphery and the casing. Further air 53 is driven outwards by vanes 54, on the back of the rotor, through a gap 50. Air flowing through passages 55, 56 protects the main and screw bearings respectively. A further arrangement, Fig: 5, includes an inlet 62 for material to be separated, the dustladen air being impelled by vanes 63 which through an opening 72 into an impeller 73 to a spiral casing 74 into a further separator (not shown). Clean air from ports 76 is impelled outwards 'by vanes 77 to an annular slot 78. An annular space 79 is supplied with clean air through ducts 80 in the hollow vanes 73.

Abstract: <PICT:0947882/C1/1> <PICT:0947882/C1/2> <PICT:0947882/C1/3> Glass phials and the like are sealed by locating the neck alongside of an electrical resistance heating surface adapted to be brought through a Joule effect to a temperature above the melting point of the glass and working the molten glass to close the phial.  The coil resistance heater A (steel 25% Cr, 20% Ai) is surrounded by a refractory (e.g. soapstone) chamber B (Figs. 1 and 2) which may be vertically reciprocated along guide rods H.  The phials are shifted in succession along guide rails L and are positioned under the flared opening D.  The neck of the phial K is centred in the interior of the coil either by adjusting chamber B or by upward movement of adjustable member M, or by adjustment of both, such adjustments being automatic.  The glass softened by the heater (brought to 1000 DEG C.) collapses and seals the phial. By modifying the dimensions of the apparatus the phial may be positioned with its neck projecting above the chamber B so that it may be gripped, e.g. by tweezers, drawn to form a solid rod and snapped off.  In a further embodiment (Fig. 4), the resistance heater includes two adjustably spaced sections N of wire or metal strip (one may be of chromium-nickel-steel and the other platinum or platinum alloy). The phials are fed into the heating space by conveyer T having phial seating means. The phial is caused to rotate during sealing by frictional engagement with stationary rail V.
