Title: Improvements in or relating to gas purifiers
IPC: B01D47/02
Filed: 1957-11-27
Abstract: 850,944. Gas purifying apparatus. TAYLOR, C. H. Nov. 12, 1958 [Nov. 27, 1957], No. 36979/57. Class 55 (2). A gas purifier comprises a vessel capable of containing liquid in a swivel chamber and in a sludge trap located below the swirl chamber, the vessel having gas inlet and gas outlet openings within the upper part thereof, baffle means arranged above the swirl chamber between the gas inlet and gas outlet openings and being provided with a plurality of small apertures to allow a small proportion of incoming gas to pass directly from the gas inlet to the gas outlet, the arrangement being such that with liquid in the swirl chamber and the sludge trap of the vessel, the gases impart a swirling motion to the liquid so that solid particles within the gas are entrained within the liquid thereby causing removal of the solid particles from within the gas. As shown the vessel may comprise an outer cylinder 1 and inner cylinder 2 and top and bottom plates 3 and 4 respectively. Through outer cylinder 1 and in the upper part thereof may be located inlet pipe 5 which directs exhaust gases for example, between cylinders 2, 3. Gases entering at 5 are preferably directed downwardly so as to impinge upon deflector 7 which due to its S-shape imparts a swirling motion to the gases. Deflector 7a may also be provided to direct gases and moisture downwardly, thereby preventing the inlet gases from becoming unduly moist. Cylinder 2 may be provided with a lower plate 8 through which projects an outlet pipe 9. Dish shaped members 12, 13 may serve to dissipate the heat content of inlet gases. Cylinder 2 is provided with a series of louvres 14 so as to give access to the gases from the outside to the inside of the cylinder, but preferably the gases are constrained to pass in one direction all the way round the outside of cylinder 2 before entering therein. A plate 15 having holes 16 and central aperture 17 may be located below cylinder 2. Liquid 18 may enter the vessel via opening 19. Bottom plate 4 is provided with drainage plug 20 so that the sludge trap may be formed by plate 15, bottom plate 4 and cylinder 1. Cylinders 1 and 2 are preferably eccentrically disposed so that gas pressure is built up in circulation, a swirling motion is imparted to liquid 18 and solid particles within the gas are thus transferred to the liquid. These solid particles form a dense sludge and separate at the bottom of the vessel as such. Fig. 5 shows a modified gas purifier of rectangular construction having inlet and outlet springs 23, 24 respectively, a perforated swirl chamber 25 having a horizontal base portion and rolled up ends, plate 26 located within swirl chamber 25 and plate 28 also perforated. Baffles 30, 31 divert incoming gases downwardly to swirl chamber 25 where cleansing ensues.

In the preferred embodiment illustrated in Fig. 1 both copper and zinc values are recovered. Fresh iron-containing brass alloy scrap is fed to step (E) where it is contacted with a filtered solution from step (D) containing CuSO 4 . The copper powder thus precipitated is filtered off (F) and purified of the metallic iron entrained therein by cycling to step (C) where it contacts a solution of CuSO 4 . The residual scrap from step (E) is recycled to step (A) where it is dissolved in a mixture of aqueous H 2 SO 4  and HNO 3 , the nitric oxides produced being recovered via step (P). The solutions from step (A) is separated from insolubles (B), and mixed with the impure copper powder from step (F), as described. The de-coppered solution from step (F) is contacted (I) with a filter cake containing ZnO and from step (H); the ZnO in the filter cake reacts with the FeSO 4  in the presence of oxygen, to form a precipitate of Fe 2 O 3 .xH 2 O and ZnSO 4  which gas into solution. The quantity of ZnO in the filter cake is adjusted so as to assure its almost complete removal from the filter cake. The precipitated Fe 2 O 3 .xH 2 O is filtered off and discarded (J), the filtrate being cycled to (G) where it reacts with an excess of solid ZnO from step M, to produce (H) a mixed filter cake of ZnO and Fe 2 O 3 .xH 2 O, which proceeds to step (I) as described, and a substantially pure ZnSO 4  solution which proceeds to steps (L), (M), and (N) where it is treated to recover ZnO and SO 3 .

Title: Improvements in electric circuit elements
Inventor: SPERRY LEONARD JAMES
IPC: H01G2/00
Filed: 1961-10-18
Abstract: 934,012. Circuit assemblies; capacitors; fixed resistors. GLOBE-UNION Inc. Oct. 18, 1961, No. 37439/61. Class 37. A resistor-capacity unit in which the capacitor comprises a pair of electrodes and associated leads bonded to an insulating member of dielectric material has a resistor formed in parallel with the capacitor by coating the entire outer surface of the dielectric member with a resistance ink, that area of the dielectric member which is not covered by the electrodes and denned thereby constituting the resistor. As shown in Fig. 16, a dielectric ceramic tube 16 has a silver electrode 22 coated over the entire interior and ends of the tube to form a common connector for the resistors, and a further electrode 24 is applied to the outside of the tube with its ends spaced from the ends of the electrode 22 to leave uncovered defined, spaced, surface portions, Fig. 3 (not shown), which are determined and accurately set by varying the length and relative position of the electrode 24. The capacitive value is derived mainly between the external electrode 24 and the portion of the fixed electrode 22 on the inside of the tube 16 opposite the electrode 24. Pretinned lead wires 26, 28 are wound around electrodes 22, 24 and soldered in place. A resistance coating comprising a paint or ink is either sprayed over the uncovered surface areas of the dielectric material and electrodes or the unit is suspended by the leads in a bath of resistance ink or paint so that two resistors 30, 32 are formed. Since the two resistors are in parallel the effective resistance of the unit can be increased by eliminating resistor 32 by grinding off the electrode 22 at the right-hand end of the tube or alternatively the resistance may be altered by sandblasting away part of the resistance coating. In a further embodiment the dielectric material is in the form of a ceramic disc 34, Fig. 17 and Figs. 8 to 11 (not shown), which has bonded thereto circular electrodes 36, 38 and leads 44, 46, the electrodes being of less diameter than the disc so that the margins and the edges of the disc when coated with a resistance ink or paint as in the first embodiment form a resistor 48. In another embodiment, the ceramic dielectric base is a plate 50, Fig. 18 and Figs. 12 to 15 (not shown), and electrodes 52, 54 are bonded to the same side of the plate to form the capacitor, leads 56, 58 being secured to the electrodes 52, 54 and a resistance coating applied as before. The electrodes 52, 54 determine the area of an uncovered portion 60 between such electrodes and that part of the resistance coating covering such area forms a resistor 62.

Abstract: 1,161,228. Sheet forming. SCHWEIZERISCHE INDUSTRIE-GESELLSCHAFT. 24 Aug., 1966 [3 Sept., 1965], No. 37874/66. Heading B5A. In a plunger assisted blow and/or vacuum moulding process an externally clamped sheet is drawn into a female mould through the opening in an apertured plate located over the mould. The opening in the plate is larger than that of the mould and the sheet slides in a controlled manner over the rim of the opening. In this way a larger area of sheet may be utilized and a more uniform drawing of the sheet is achieved. In one embodiment, illustrated in Fig. 5b, the sheet is clamped and an apertured plate 47 over which the sheet may slide raised to contact it. Plunger 45a is then lowered to pre-draw the sheet through the opening in the plate and into a mould 44 which is simultaneously raised. The escape of air from the mould is controlled so that the initially balloons upwardly as shown, this further improving the thickness distribution in the article. In a second embodiment, see Fig. 3, the sheet is externally clamped at 11, lightly clamped between apertured plates 10a and 7, and then drawn into moulds 4<SP>11</SP>, through the openings in the lower plate 7, by ram actuated plugs 5a. The plates 10 and 7 are retained in the operative position when the mould and plugs are withdrawn so as to facilitate removal of the drawn article from the mould. In a third embodiment (see Fig. 4, not shown) this removal is assisted by providing the base of the mould cavities with plungers.

Abstract: 1409969 Alpha-numeric displays SUWA SEIKOSHA KK 10 Aug 1973 [16 Aug 1972] 37962/73 Heading G5C A display device comprises a nematic liquid crystal material sandwiched between square or rectangular transparent plates having surfaces treated so that molecules in contact with each surface are aligned in different directions, the directions being at an angle to the edges of the plates. Material having positive dielectric anisotropy is sandwiched between plates which have been rubbed. The device is mounted between polarizing plates with their planes of polarization aligned with the said directions. The direction of the plane of polarization of light turns as light passes through the liquid crystal and light passes through the panel. When a sufficient potential is applied across an area of the liquid crystal the molecules are aligned, light cannot pass through and the area appears dark. When a lower potential is applied this effect is partial and the area appears light or dark according to the direction of observation. The device is used in watches with sevensegment electrode arrays.

Abstract: 1,198,613. Producing crimps or folds in fibres. I.W.S. NOMINEE CO. Ltd. 11 Aug., 1967 [26 Aug., 1966], No. 38440/66. Headings D1F, D1K, D1S and D1W. A method of folding textile fibres comprises continuously holding and advancing an unfolded strand or layer of textile fibres at a first speed to a folding zone and continuously holding and conveying the folded strand or layer between a pair of spaced surfaces away from the folding zone at a second speed slower than the first, the location of release of the unfolded strand or layer being so close to the intake to the spaced surfaces, and the folding zone being thereby so small, that the strand or layer is folded at the intake to the spaced surfaces into simple folds or waves having an amplitude determined by the spacing between the spaced surfaces, the second speed being related to the first speed in accordance with the amplitude and pitch of the folds or waves. The fibres may be fed to the folding zone between a conveyor belt and a second belt or a plate, the belt or each belt passing around a roller or guide of small radius at the entry to the folding zone. Similarly the spaced surfaces may be formed by two belts or one belt and a plate which may be a continuation of the feed plate. The spaced surfaces may pass the fibres through a steaming zone followed by a drying zone to set the folds. A setting agent, e.g. an aqueous solution of an alkali metal or ammonium sulphite or bisulphite, may be applied to the folded or unfolded fibres. The strand may be a sliver, or a plied yarn which receives a sinusoidal crimp or the plies of which may separate and form helices or become kinked. The fibres may be of wool, or nylon, cellulose acetate or polyethylene terephthalate. A pile fabric may be formed by passing a crimped strand or a spaced array of strands onto the surface of a backing fabric coated with latex adhesive, or between two such fabrics and slitting the sandwich thus formed to form two pile fabrics.
