Title: Separation of Hydrogen from other Gases
Inventor: BUCKLAND IVOR JOHN
IPC: B01J8/24
Filed: 1967-03-15
Abstract: 1,163,279. Separating hydrogen from gas mixtures. INTERNATIONAL NICKEL Ltd. 15 March, 1968 [15 March, 1967], No. 12230/67. Addition to 1,090,479. Heading B1L. The process of the present specification is modified by fluidising the sorbent palladium sponge or powder with the gas to be purified during the sorption stage and with the purified hydrogen being released during the desorption stage. The palladium sponge or powder may be replaced in whole or in part by the palladium alloy or by the inert particles coated with palladium or the alloy; these materials are described in Specification 1,147,010. Thus, impure hydrogen-containing gas, e.g. comprising 75% hydrogen and 25% nitrogen from cracked ammonia, is passed by compressor 10 from reservoir 9 to supply vessel 11, and thence at about 520 p.s.i.g. to container 1 under such conditions that the sorbent palladium 2 is fluidised, the pressure rises to about 5000 p.s.i.g. within container 1 and the sorbent becomes saturated. Valve 16 is then closed, and valve 22 opened to allow the impure hydrogen-containing gas to be bled from container 1 and passed to vessel 11 for subsequent reprocessing. Valve 22 is then closed and valve 19 opened, and most of the desorbed hydrogen passed to receiver 17, until the excess pressure in container is about 5 p.s.i.g., when the cycle is restarted. Part of the desorbed hydrogen is returned by lines 8 and 5 and pump 4 to keep the bed fluidised during desorption. Heaters 28 are used to assist desorption.

IPC: G01P1/12
Filed: 1939-04-24
Abstract: 529,038. Recording apparatus. V. D. O. TACHOMETER AKT-GES. April 24, 1939, No. 12234. Convention date, June 14, 1938. [Class 106 (iv)] In an apparatus for recording data relating to the working of machines, a number of record discs are inserted simultaneously and automatically inscribed in succession by the recording members. The discs I to IV, in an embodiment, are superposed and connected at their peripheries so that the edges of the cutaway portions 4 with like designations a-a, b-b &c. are in register. During the recording process, the rear disc VI is rotated on the boss 6, while the remaining discs I to V are severed in turn by a stationary knife 14 and held motionless, thus allowing the recording members 11, 12, 13 to fall through the cut-away portions and successively inscribe the discs. Reference has been directed by the Comptroller to Specifications 172,117 and 195,759, [both in Class 106 (iv)]

Abstract: 465,385. Uniting by fusion. LINDE AIR PRODUCTS CO. April 30, 1936, No. 12262. Convention date, May 25, 1935. [Class 83 (iv)] [Also in Group XI] An oxyacetylene welding nozzle 10 formed with two more discharge passages for providing preheating flames 33 is used with a stem having its outer edge bent at 120‹ so that as the nozzle is drawn backwardly in the plane of the seam over the surfaces to be welded the main flame tends to restrain the flow of the molten puddle P. The gaseous mixture preferably contains an excess of acetylene which tends to carburize the base metal surfaces in advance of the puddle, thereby lowering their melting point and reducing the surface oxide.

The rotors have respective drive means 16, 17 by which, in one mode, the rotors may be driven at a constant speed and, in another mode, the rotors may be indexed to place the sets of spaces 4, 5 successively beneath the dispensers 13, 14. The modes of operation of the drive means may be manually or automatically controlled. Samples to be analysed are contained in cups 22 carried by a conveyor 21 which may be operated to index the cups one by one to location 23. The drive means 15 is manually or automatically controlled so that the arm 11 may be pivoted first to location 23 where the dispenser 13 is placed above a cup 22 and is remotely actuated to withdraw a predetermined amount of sample from the cup, then to location 18 where the dispensers 13 and 14 withdraw measured amounts of diluent and reagent respectively from reservoirs 19 and 20, and finally to the leading location associated with a rotor, e.g. rotor 9, where the dispensers discharge their contents to a pair of receiving spaces 4, 5. The rotor is then indexed to bring a desired number of pairs of receiving spaces to the loading location, so that the loading steps of the arm can be repeated. The same loading procedure may be repeated with the rotor 10 whilst the rotor 9 is run up to a constant speed to cause the materials to be centrifuged in the chambers 6 so as to have their light transmission properties analysed by means of an optical device, Fig. 4 (not shown).

IPC: C07D471/14
Filed: 1958-04-23
Abstract: The invention comprises dipyridyl derivatives of the formula: <FORM:0857501/IV(b)/1> wherein R represents a branched or unbranched, saturated or unsaturated alkyl radical located at positions 4 or 5, and 41 or 51 and X stands for an anionic radical, such as chloride, bromide, iodide and p-toluenesulphonate radicals.  The novel compounds may be prepared by interaction of the corresponding di-substituted a , a 1-dipyridyl with an ethylene glycol di-ester. The reaction may be effected by heating the reagents together alone or in the presence of an inert solvent or diluent, for example nitrobenzene or b -ethoxyethanol. Certain of the new dipyridyl derivatives may be obtained by reacting a salt of the formula: <FORM:0857501/IV(b)/2> in which Y is an anionic radical with a salt derived from an anionic radical X, e.g., silver iodide, or silver chloride.  The new compounds may be used in herbicidal compositions.ALSO:Herbicidal compositions contain, as the active herbicidal ingredient, one or more dipyridyl derivatives of the formula:  <FORM:0857501/VI/1> wherein R stands for a branched or unbranched saturated or unsaturated alkyl radical located at positions 4 or 5 and 41 or 51, and X stands for an anionic radical such as chlorine, bromine, iodine or p-toluensulphonate radicals. (For preparation see Group IV(b)).  The compositions may be liquid compositions, for example aqueous solutions of the active ingredients.  Wetting agents such as alkali metal salts of dinaphthylmethane disulphonic acids, alkali metal salts of long chain aliphatic sulphates, and condensation products of ethylene oxide with an alkyl phenol, and/or humectants, for example, calcium chloride, glycerol, ethylene glycol and water-soluble polyethylene glycols, may be present.  Agents which improve the adhering properties of the composition to the plant, such as sodium carboxymethylcellulose and ammonium polymethacrylate may also be present.  The compositions may also be solids containing inert pulverulent diluents such as talc, china clay, gypsum, basic slag, kieselguhr, bentonite or other colloidal clays.
