Title: Thermostable inorganic cation exchanger prepn. - by colloidal gel formation of Gp=IV metal salts in non-aq. solvents, followed by comminuting and drying
IPC: B01J39/08
Filed: 1969-12-04
Granted: 1978-11-03
Abstract: In preparing a thermostable, inorganic cation exchanger from colloidal gels of Gp.IV metal salts solns., the improvement comprise using solvents other than water for the salts and for the pptg. anions solns. Suitable solvents are e.g. glycols and their esters or ethers, DMF, DMSO, etc. Gel formation may be direct or in the form of solidified emulsion globules opt. in presence of carbonisable material. The process is an improvement over the related patent 1605524 in which water is the sole reaction medium for pptg. the metal salt. Use of an organic solvent gives mechanical strong solid gels of the insoluble salts instead of pptn. crystals which are mechanically more or less solid.

Abstract: 1,051,420. Television. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 2, 1965, [March 3, 1964]. No. 8955/64. Heading H4F. In a closed circuit television system in which a camera C, Fig. 1, located at the bows of a ship is directed at a slant angle D downwardly on to the surface of the water, the viewing screen of the receiver, Fig. 2, is provided with range lines 1-5, each line corresponding to a distance from a point at or near the bows of the ship measured at sea level in a direction parallel to the longitudinal axis of the ship, Fig. 3, not shown. The actual range values of the lines depend upon the " effective " lens angle # (the meaning of which is explained in the Specification with reference to Fig. 4, not shown), the angle of declination D, the freeboard F (or draught) and in some cases, the pitch angle # of the ship. In Fig. 2 the range lines are engraved on a piece of transparent material located in front of the screen and a rotatable cylinder CAL carries vertical rows of range scales for the lines each row corresponding to a given value of freeboard F for given values of the angles D and #. Alternately the transparent material on which the range lines are engraved may be moved in front of the screen in accordance with the freeboard F. The range lines may be marked on the outside surface of the screen itself, they may be formed within the screen, or they may be superimposed on the picture electronically by means of a scanning spot. The camera may be pivotally mounted to allow for pitching of the ship and gravity biased so that the angle of declination remains substantially constant. The range lines are not necessarily equi-spaced as shown and in addition vertical lines may be provided on the screen to indicate sideway distances. Two cameras may be arranged on one mount at two different angles of declination so that a larger region in front of the ship is covered, the regions covered by each camera overlapping slightly. The ranges may be " written " electronically on the screen against each range line and changed automatically with changes of angles D and/or # and/or changes of the freeboard F.

Cigarettes or cigarette packets are carried by carrier 15 rotatably mounted at 14 in arm 13, the latter being guided between slides 11, 12 fixed on rotatable disc 5 and being supported and influenced radially by roller 9 of said arm engaging fixed cam track 8. Additionally, shaft 14 carries gear 16 engaging with 17 carried by the arm and positionally controlled by its roller 19 engaging cam 23 fixed to disc 5. Operation.-Cigarettes are received on carrier 15 at the elevated position being held pneumatically whilst the disc rotates constantly clockwise. As it does so, roller 9 is urged by track 8 to move the carrier inwards and downwards and this movement, in turn, causes roller 19 to run on cam 23 and thus rotate shaft 14 and therefore the carrier 15 together with cigarettes. At the lowest position shown in Fig. 1, carrier 15 is inverted and has also been rotated through 90 degrees so that the cigarettes fall off appropriately oriented.

Abstract: 1,238,063. Removal of sulphur oxides from flue gases. NORTH AMERICAN ROCKWELL CORP. 14 May, 1968 [15 May, 1967], No. 22914/68. Heading C1A. Sulphur dioxide and sulphur trioxide are removed from flue gases by treating with a molten salt mixture containing alkali metal carbonates at a temperature of at least 350 C. to form alkali metal sulphites and sulphates respectively; these products are then converted to the carbonates, for recirculation, and hydrogen sulphide by one of two processes. In a single stage process the sulphite and sulphate present in a molten salt mixture are treated with a carbon and hydrogen containing material at a temperature of at least 350 C., preferably 350-650 C. In a two-stage process the sulphite and sulphate present in a molten salt mixture are first treated with a carbonaceous material at a temperature of at least 350 C., preferably 350-650 C., to form sulphides and carbon dioxide, and the sulphides are then treated with a mixture of steam and carbon dioxide, preferably at a temperature below 450 C. at which the mixture is molten. Alternatively, the last stage may be carried out at a temperature as low as 100 C. The initial molten absorbent salt mixture is made up from one, two or three alkali metal carbonates either with or without diluent salts, subject to the condition that at least two alkali metals are present. A suitable mixture contains, in mole per cent, 45  5 of lithium carbonate, 30  5 of sodium carbonate and 25  5 of potassium carbonate. Another suitable mixture contains, in mole per cent, 15-60 K<SP>+</SP>, 40-85 Li<SP>+</SP>, and 0-20 Na<SP>+</SP> as cations, and 10-98 Cl-and 2-90 CO 3 - as anions. An alkali metal sulphite content of 10-30 mole per cent is preferred in the salt mixture after the absorption stage. In the single stage regeneration process the carbon and hydrogen containing material may be hydrogen mixed with a solid or liquid carbonaceous material, e.g. activated carbon, or may consist of sludges, cokes, asphalts, tars and pitches from petroleum and coal processes, supplemented with added hydrogen if required. Alternatively hydrogen may be generated in situ from steam and a carbonaceous material. In the two-stage regeneration process the carbonaceous material may be charcoal, activated carbon, coke, asphalt, tar, pitch or a hydrocarbon. Carbon dioxide produced in the reducing stage may be employed in the final reforming stage.

A ring-forging press comprises a vertical mandrel 10 and a forging ram 7 movable horizontally and mounted in a horizontal C- frame 3. The ring 20 is supported on a bearing surface 21 and displaced linearly during retraction of the ram at an angle to the forging axis so that it is rotated by the ram on the forward stroke. The displacement may be effected by an hydraulic piston-cylinder unit 24, Fig. 4, which moves the bearing surface 21 or by an hydraulic unit (26), Fig. 5 (not shown), with a beam (30) which moves the ring. The displacement moves the ring away from the mandrel and the next advance of the ram causes the ring to roll on the mandrel, Fig. 3c (not shown). The unit (26) may be mounted in a slot (31) for adjustment as the ring diameter increases. The mandrel 10 has an eccentrically mounted smaller mandrel 19 which is used initially on a pre-pierced billet. The mandrel 10 is moved vertically by an hydraulic unit 11 to bring either the smaller mandrel 19 or the main mandrel 10 in line with the ram 7. A ring-flattening press (32), Fig. 6 (not shown), is mounted to act vertically on the ring at the side of the ring-forging press. The rams of the presses are arranged to act alternately.

The bacteriophage may be T4 or T2 phage. In Examples, the conjugates comprise bovine pancreatic ribonuclease, bovine serum albumin, 'rabbit serum albumin, rabbit immunoglobulin IgG, lysozyme insulin. In carrying out the test, the reduction in activity of the phage towards the bacteria is determined after reaction of the conjugate with the solution under test. If the conjugate comprises antigenphage, antibody may be determined by mixing the conjugate and test sample, adding soft agar containing the bacteria and pouring the reaction mixture on to agar plates, or alternatively by adding bacteria, a hyper-immune anti-phage serum and soft agar then plating. In an alternative method which may be used for determination of antibody or antigen, the inactivation of a protein antigen-phage conjugate by added antibody in the test mixture is inhibited by addition of free protein antigen.
