Patent GB-1523459-A (GB)
Title: Air scrubber
IPC: B04C5/04
Filed: 1975-10-24
Abstract: 1523459 Centrifugal separators E H CUMPSTON 24 Oct 1975 43818/75 Heading B2P An air scrubber, Fig. 1 has air inlets 82, a scrubbing liquid inlet 83, a relatively low pressure chamber 79 along which the air and liquid pass and a fan 88 for forcing the air and aerosol particles helically into an annular chamber 80 of relatively high pressure, the outer wall of chamber 80 having small apertures 100 for removing aerosol particles together with entrained dust particles. Additionally slots 92-94 on the lower portion of the outer wall 77 of the chamber 80 serve to separate liquid from the air (and to recirculate part of it into the incoming air stream). A channel 95 which is adjustable in height to regulate the proportion of liquid recirculated and the proportion drained from the scrubber, is mounted on the exterior of the outer wall 77. The difference in pressure between the outer and inner chambers promotes the removal of liquid and aerosol particles. The region having the apertures 100 may be slightly roughened as by shot blasting.  The rows of slots 92-94 may be replaced by two annular zones between separate wall portions of the wall 77. The zones are of toothed form, Fig. 6, and define openings which can be adjusted in size by relatively having the wall portions. The fan 88 may have concavely shaped blades and is driven by a central motor 89. The scrubber is able to remove very small particles (e.g. 0.1Á) from air.

Title: Improvements in or relating to sintered products
IPC: B22F3/10
Filed: 1963-11-07
Abstract: <PICT:0990316/C6-C7/1> In a powder metallurgical process for forming sintered long slender shapes such as thin rods and bars, warpage of the shapes during sintering is inhibited by forming a unitary assembly of a plurality of the compacted slender shapes lying adjacent each other and connected together by thin longitudinal webs, and after sintering the assembly the sintered shapes are separated from each other by severing the webs.  As shown in Fig. 3, the compacted and shaped assembly comprises long thin rods 7-11 connected together by webs 7a-10a and the webs may be grooved to aid severing after sintering.  During sintering the webs may be supported by a refractory form such as magnesia (Fig. 2, not shown).  The ratio of length to cross-sectional thickness of the shape is at least 5:1 and the web thickness may range from 0.025-0.075 inch with a ratio of thickness of cross-section to thickness of web of at least 4:1.  A specific example relates to the production of rods of a tool steel composition comprising 60% steel powder of 20 micron size and 40% TiC powder of 5-7 micron size. The powder mixture is pressed, shaped and vacuum sintered at 1450  DEG C. for 1 hour.  The sintered rods 4 1/2 inches x 1/8 inch are severed from the webs and finish ground to size.  The process may also be applied to the following materials: - W, Mo, Cr, Ta, Nb, V, Ti, Zr, Hf, mixtures of two or more of these metals, and carbides, borides, nitrides and silicides of these metals liquid phase sintered with a matrix metal such as Cu and its alloys, Fe, Co and Ni and their alloys, Ag and its alloys.

Abstract: 1,153,565. Preventing dye migration. BADISCHE ANILIN - & SODA - FABRIK A.G. 7 Oct., 1966 [9 Oct., 1965], No. 44875/66. Heading D1B. Dye migration in pad dyeing of fibrous material with vat, disperse and/or fixing dyes is prevented by applying before, during or immediately after the padding in of the dye a cationic polymer which is a polymer or copolymer of a vinylimidazole or ethyleneimine polymer or a salt or quaternary ammonium compound of such a polymer or copolymer. In particular poly - N - vinylimidazole is particularly advantageous as are the quaternary ammonium compounds of polyethyleneimine in which up to 20% of the nitrogen atoms have been quatenized. Preferably the cationic polymer is applied together with the dye by dissolving in the padding liquid. In examples cotton, rayon, polyester, cellulose triacetate, nylon, and mixtures of polyester/cotton and polyester/rayon materials are dyed. 2.5 to 200% by weight of polymer with reference to the dye is preferably used. Specified compositions for use in the above process are referred to.
