Abstract: 1,135,088. Break-spinning apparatus; cleaning machines. VESESOJUZNY NAUCHNOISSLEDOVATELSKY INSTITUT TEXTILNOGO I LEGKOGO MASHINOSTROENIJA. 24 March, 1966, No. 13020/66. Headings DID and D1F. In break-spinning machines comprising a plurality of spinning elements each with a suction tube, all the tubes, 1, Fig. 2 are connected to a fan 4 and a fibre-collector 5 by an air-main 3 in which the pressure is kept at a predetermined value by inflow and outflow valves 11, 7 at opposite ends of the main. In each element 2, Fig. 1, material drafted at 22 is spun into yarn in a chamber 2 where an air-vortex is created. Loose fibres arising from a break in the yarn pass through the tube 1 to the main, and are drawn into the collector by the fan. When, through overfilling of the collector, the pressure rises at the exit end of the main, an adjustably spring- loaded flap valve, Fig. 4, not shown, is opened; when, through fibres clogging one of more of the tubes 1, a fall in pressure occurs at the inlet end, it opens a valve, comprising a venturi with an adjustably spring-loaded cone 13, Fig. 3, not shown. In each chamber, the working pressure is pre-set to a valve indicated by a manometer 19 by adjusting the resilient wall of a pitot-tube 17 in the tube 1. A throttle-disc 18 is also provided in each tube.

A grain harvesting, thrashing and separating machine has a mobile frame 7, e.g mounted on a motor lorry 6, and cutting mechanism from which reapings are sucked through a duct 23 into an air-impelling thrashing fan 17, which delivers thrashings through a duct 16 into a separating chamber 9, from which grain passes into a receiver 13 and chaff is sucked through a duct 14 by a fan 18, which discharges the chaff through an outlet 22. The cutting mechanism is mounted in a frame 26 attached to sleeves 38 sliding on guides 36 supported by an outrigger arm 27, e.g. detachably connected to the frame 7, which arm also supports a cylinder 39 carrying pulleys 42 and a plunger 43 carrying a pulley 44. A cable 46 is trained round the pulleys and secured at each end to a sleeve 38. The frame 26 can thus be raised or lowered by hydraulically raising or lowering the plunger in the cylinder. The outrigger is supported by a wheel 34.

Title: Centrifugal separators
IPC: B04B1/12
Filed: 1972-03-21
Abstract: 1325413 Centrifugal separator WESTFALIA SEPARATOR AG 21 March 1972 [30 April 1971] 13188/72 Heading B2P A centrifugal separator drum for concentrating solids suspended in a liquid comprises a concentration chamber 10 the radially outer part of which communicates with nozzles 5 for the continuous discharge of concentrate to the outside, and valve means 4 which, in its open position, uncovers a plurality of orifices 9, Fig. 1, or an annular slot 16, Fig. 3, at the drum periphery for the complete ejection of concentrate and liquid from the chamber. In Fig. 1, a piston valve 4 embraces the outside of the bottom drum section 1 and is equipped with a number of nozzles 5 distributed around its periphery. When control liquid fills a closing chamber 6 the valve 4 is in its closed position as shown. Its top edge is forced into contact with a sealing ring 7 and the inlet openings 8 of the nozzles 5 communicate through some of the orifices 9 with the chamber 10, there being a greater number of orifices 9 than there are nozzles 5 and those orifices 9 not communicating with the openings 8 being kept closed by the valve 4. To empty the drum completely, the supply of control liquid is opened and the latter flows from the channel 11 through passages 12, 13 to an opening chamber 14 thereby causing the valve 4 to open so that the nozzle openings 8 lie beneath the orifices 9 which thus communicate freely with the outside. Rinsing water is supplied to the chamber to rinse out the solids. In a modification, Fig. 2 (not shown), the piston valve carrying the nozzles is arranged into the drum interior. When the valve is in the open position an annular slot is opened up between the valve and the drum cover (2) and the concentrate passing through this slot then passes outside through ejector slots (17) in the drum bottom section (1). In Fig. 3, the small tubes 18 lead from the radially outer part of the chamber 10 to the discharge nozzles 5 through which the concentrate is continuously centrifuged out when the valve 4 is in its closed position. When the feed is closed, the drum empties to the level A which corresponds to the level of the discharge bores of the nozzles 5. After opening of the valve 4 the drum contents are ejected through the annular slot 16 and the ejector slots 17. In any of the above arrangements, the control mechanism for the piston valve may be coupled to a switch which in the event of any imbalance in the drum automatically initiates the displacement of the piston valve into the position in which it exposes the orifices 9 or the slot 16.

Title: Improvements relating to the measurement of condensation nuclei
IPC: G01T5/04
Filed: 1955-05-09
Abstract: 785,943. Photo-electric measurement of condensation nuclei. GENERAL ELECTRIC CO. May 9, 1955 [May 24, 1954], No. 13405/55. Class 40 (3). A method of counting the condensation nuclei within a gas sample includes the steps of drawing the gas into a chamber, rapidly reducing the pressure in that chamber to a first value so that supersaturation occurs, reducing the pressure still further to a second value so that water vapour forms about condensation nuclei of a size greater than a certain minimum dependent upon the degree of supersaturation, this second pressure reduction being slower than the first one but still fast enough to ensure adiabatic expansion of the gas, and measuring the density of the fog so formed in the chamber to provide an indication of the number of condensation nuclei larger than said minimum size. By varying the initial pressure reduction each time, a series of readings may be obtained of the number of nuclei having sizes greater than certain minima. Apparatus for carrying out this method comprises three chambers, the first two being interconnected by a valve which can be quickly operated to provide the rapid pressure reduction of the gas in the first chamber and the second and third chambers being joined by a restricted passage allowing of the second slower pressure reduction ; and means for measuring the fog density. In the apparatus shown, the first chamber 4 is connected through a valve 16 to a source of gas and through a valve 9 to the second chamber 10. Valves 9 and 16 are identical, each comprising a ball-bearing 18, which is spring-pressed as at 20 on to a ring 19, and a pivoted lever 21 for opening the valve. Chamber 10 is joined to the third chamber 12 by a capillary tube 11, chamber 12 being connected through valve 14 to a vacuum pump. The chambers 10, 12 have plungers movable therein to adjustable positions whereby the volume of the gas in each chamber can be raised. Light from a lamp 1 passes through chamber 4 to a photo-tube 3 connected to a measuring device 7, calibrated in terms of numbers of condensation nuclei. In use, with all valves open, the gas sample is drawn into the chambers and then valve 9 is closed. Chambers 10, 12 are evacuated and valves 14, 16 closed. Valve 9 is then opened to provide a rapid reduction in pressure which is followed by a slower pressure reduction as the gas penetrates into chamber 12. When the pressure in the chambers have become equal, the meter 7 (which has been precalibrated) is read. The plungers in the chambers 10, 12 are then moved so as to vary the volume of each chamber, while keeping the total volume constant, and the steps are repeated.
