Title: Vortex nucleation scrubbing
IPC: B01D47/10
Filed: 1972-10-02
Abstract: 1445978 Centrifugal separators CARRIBBEAN PROPERTIES Ltd 26 Sept 1973 [2 Oct 1972] 45266/72 Heading B2P A process for the separation of particles from a gaseous phase in which the particles are suspended comprises (a) continuously supersaturating the gaseous phase with the vapour of a liquid which is capable of wetting the particles until at least some of the particles have been wetted by the vapour condensing on them, and (b) continuously spinning the supersaturated gaseous phase to centrifugally separate the wet particles therefrom. The supersaturation may be accomplished either (1) by saturating the gaseous phase at a relatively elevated temperature, e.g. by evaporation of the liquid or introduction of the vapour, and adiabatically cooling the saturated gaseous phase until condensation occurs; or (2) introducing the vapour at a relatively elevated temperature into a relatively cooler gaseous phase.  One simple form of apparatus, not shown, for carrying out the process comprises a generally vertical conduit, having an inlet for the particle-bearing gaseous phase, preferably directed circumferentially around its vertical axis, near its lower end, one or more similarly circumferentially directed inlets for vapour or evaporatable liquid preferably situated above the gaseous phase inlet, an outlet for the scrubbed gaseous phase at the top, and an outlet for the condensed vapour carrying the scrubbed particles at the bottom. Another form of apparatus, Fig. I, comprises two coaxial hollow members 1, 11 defining between them an annular venturi conduit having a convergent portion 13. a throat 14 and a divergent portion 15. The member 1 is enclosed by insulation 18. An inlet 5 for gaseous feed, e.g. dust-bearing air, is tangential to the wall 2 of the member 1. Scrubbing fluid, e.g. saturated steam, is supplied through a valved conduit 10 and nozzles 8 tangentially directed to the wall 2. A mist collector 17 comprising a cylindrical mesh of knitted filaments is supported by a plate 16 having holes 20 for the passage of scrubbing liquid and centrifugally separated wet solid particles into the hollow conical bottom 4 of the member 1 from which they are continuously withdrawn via a valved outlet 6. An exhaust fan 21 may be installed within the member 11 to spin the gaseous phase as it is discharged to provide final scrubbing thereof. A further form of the apparatus, Fig. 2, comprises a conduit 1 made of a series of one or more Venturi tubes having a tangential inlet 5 for particle laden gaseous fluid and a scrubbed gas outlet 11 which may be shielded by a conical baffle 26 and a mist collector 17. Scrubbing fluid is fed through tangential nozzles 8 connected to a manifold 10 and through one or more valved nozzles 24. The scrubbing fluid supplied through the nozzle(s) 24 may be a gaseous coolant, e.g. part of the scrubbed gas discharged through outlet 11 and compressed and cooled before being recycled.

Title: Improvements in or relating to Movement Control Arrangements for Corpuscular Beam Apparatus
IPC: H01J37/02
Filed: 1967-10-05
Abstract: 1,193,977. Discharge apparatus. MAX-PLANCK-GES., ZUR FÍRDERUNG DER WISSENSCHAFTEN E.V. 5 Oct., 1967 [24 Feb., 1967], No. 45410/67. Heading H1D. Means for moving an object disposed in the vacuum chamber of a corpuscular beam apparatus, e.g. an electron microscope, comprises an adjusting rod arrangement extending through a seal in the wall of the apparatus and carrying the object at one end, the other end being attached to a control drive adapted to move the arrangement longitudinally for movement of the object in one cirection, and a second control drive being adapted to deform the rod arrangement thereby producing movement of the object in an orthogonal direction. In Fig. 2 the object 3 is a diaphragm mount, but it may be a specimen or part of a polepiece, and is attached to the outer portion 25 of the control-rod arrangement extending through a gasket 1 in the wall of the chamber. The centre portion 26 of the controlrod arrangement is flat and secured by pins 31 and 32 in slots in the outer portions 25 and 27. A screw-threaded end 7 of the rod portion 27 co-operates with a screw-threaded sleeve formed of two rigidly connected parts 8 and 9, the outer part 9 being screw-threaded in a fixed portion 10. Rotation of the hand grip 11 therefore causes translation of the rod according to the difference between the pitches of the two screwthreads. The rod arrangement passes through a sleeve 20 which is pivoted at its left end (about axis 30, Fig. 1, not shown) and is rotatable about the pivot by means of a second control drive 5 similar to the first control drive 4 and acting via a ball 33 and a bearing-plate 34 and opposing the action of a return-spring 39. Any rotation thus produced is transmitted to the rod arrangement through a bearing-plate and a roller 23 to cause transverse movement of the object 3. A compression spring 36 is located between a part 37 of the sleeve 20 and an abutment surface 38 on rod portion 25 and takes up any slack in the rod arrangement as well as acting as a return spring for the first control drive 4.
