Patent GB-856306-A (GB)
Title: Improvements in or relating to the separation of niobium and tantalum compounds
IPC: C01G33/00
Filed: 1957-12-06
Abstract: Niobium values are recovered from mixtures of niobium and tantalum oxides, for example columbite ore, by contacting the mixture with a stream of chlorinating gas in the presence of at least a stoichiometric amount, as defined, of a carbonaceous reducing agent, at a temperature sufficient to convert niobium oxide to niobium oxychloride, the concentration of chlorine vapour in the exiting gases being so low that the chloride vapours are predominantly niobium oxychloride, and that not all the niobium oxide at the exit point of the gases is chlorinated.  The carbonaceous reducing agent may be derived from the chlorinating gas, as when phosgene is employed, or may be provided separately, for example as coke.  The chlorination may be carried out either in static or fluidised beds. To ensure that some niobium oxide is present at the exit point of the gases, a second bed of mixed oxides, or niobium oxide, may be provided through which the gases having the first bed pass.  As this second bed becomes enriched in tantalum, it may be employed to feed the main bed.  The chlorinating temperature may be between 600 DEG -1,000 DEG C.  The chlorine concentration in the exit gases is preferably 0.1% to 0.5% by weight.  Suitable chlorinating and carbonaceous reducing agents include chlorine and carbon, chlorine and carbon monoxide, phosgene, and chlorinated hydrocarbons, for example carbon tetrachloride.  From the exiting gases, niobium pentachloride and oxychloride may be condensed together with chlorides of impurities such as of titanium, tin, iron or manganese and other metals.  If desired, after the bed has been substantially depleted of niobium, the bed may subsequently be further chlorinated to remove all the remaining niobium contaminated with a considerable proportion of tantalum, thereby obtaining in the bed a niobium-free solid residue.

A machine for stacking wooden boards or similar articles has a conveyer member which assembles articles in a layer on a table, feeler means to sense when the layer is complete, and a displacement mechanism for transferring the layer of articles to a stacking platform. A chain or belt I, running over pulleys 4, 6, conveys single articles 3 transversely on to a table 2, each article pushing the previously assembled article or articles along the table, thus forming a parallel layer. Rail 7 rest on top of the articles to keep the layer correctly arranged, and each article passes over an arm 9 on a carriage 10 as it arrives at the table. A feeler member (32), Fig. 4 (not shown), is positioned towards the far end of the table 2, and when this feeler is actuated by an article, signifying the presence of a complete layer, a motor is started to drive an endless chain 11, moving the carriage 10 along the table. The arm 9, along with carrying arms 24, is raised by linkage, Fig. 2 (not shown), attached to the carriage 10, and the layer of articles 3 is thus transported on the arms 24 to a position 24a above the stacking platform 43. When the carriage 10 reaches the far end of the table, the arms 24 are lowered on to the stack 14 and drawn back by the return motion of the carriage, leaving the layer of articles 3 disposed on top of the stack 14, which is then moved downwards on its base 43 by a motor 45 so that it is ready to receive the next layer of articles. The position of the feeler member along the table can be varied according to the length of the stack required, the mechanism being mounted on a carriage which may be driven by a chain (38), Fig. 4 (not shown).

Title: Improvements in or relating to a process for the preparation of heterocyclic phosporic acid amides
IPC: C07F9/6506
Filed: 1960-11-11
Abstract: Heterocyclic phosphoric acid amides are obtained by reacting an NN1-carbonyl diheterocyclic compound wherein each heterocyclic ring is five membered, unsaturated, substituted or unsubstituted, and has at least two nitrogen atoms incorporated therein, with orthophosphoric acid or its mono- or di-esters. Specified N,N1-carbonyl compounds are carbonyl-diimidazole, carbonyl-di(4- or 5-methyl imidazole), carbonyl-di (triphenyl imidazole), carbonyl-di-(1, 2, 3-triazole), carbonyl-di-(1, 2, 4-triazole), carbonyl - dibenzimidazole, carbonyldibenz-1, 2, 3-triazole and carbonyl-di (3, 5-dimethyl pyrazole).  Specified phosphoric acid esters are mono- and di-phenyl phosphoric acid and their nuclear substituted derivatives, naphthyl phosphoric acid and its nuclear substituted derivatives, and benzyl-, p-nitrobenzyl-, cyclohexyl, adenosine-, dibenzyl, di-p-nitrophenyl-, diethyl and dicyclohexyl phosphoric acids. When orthophosphoric acid or its monoesters are used the heterocyclic monoamide first formed may be reacted with a second molecule of the N, N1-carbonyl compound to form a heterocyclic phosphoric acid diamide.  The reaction may be exemplified by the following scheme.: <FORM:0950290/C2/1> wherein R1 and R2 which may be the same or different are hydrogen, or an alkyl, aralkyl, aryl, cycloalkyl or nucleoside group.  The above referred to diamide products have the formula: <FORM:0950290/C2/2> wherein N represents the heterocyclic ring as defined above. The products in which at least one of R1 and R2 is a hydrogen atom may be suitably isolated in the form of their organic base or alkali metal salts and may be reacted with alcohols to form esters, with amines to form amides, or with carboxylic acids to form anhydrides which are useful in the peptide synthesis; also they may be reacted with phosphoric acid or its mono- or di-esters to form pyrophosphates which reaction may be applied in the synthesis of coenzymes. Examples are given for the production of diphenyl-, monophenyl-, monobenzyl-, p-chloro-phenyl-, betanaphthyl-, monomethyl glycol-, and monothymyl-phosphoric acid mono-imidazolides and ortho-phosphoric acid mono- and di-imidazolides.

Abstract: 826,508. Gas turbine power plant. ARMSTRONG SIDDELEY MOTORS Ltd. Dec. 23, 1957 [Dec. 28, 1956], No. 39397/56. Class 110(3). In an axial-flow gas turbine power plant having a compressor and turbine rotor assembly associated with a thrust bearing which is subjected to the difference between the oppositelyacting thrusts of the turbine and compressor rotors during operation, a plurality of coaxial thrust pistons is provided, each secured to and axially-spaced along the rotor assembly and coacting with an associated stationary reaction piston so as to form a pressure chamber to which the compressor outlet pressure is communicated in parallel, the sides of the pistons opposite to the pressure chambers communicating with the atmosphere. A hollow shaft extension is provided at the side of the turbine remote from the compressor, the shaft being supported in a balltype combined journal and thrust-bearing 12. The end of the shaft is of reduced diameter and three thrust pistons 29 are mounted thereon, being secured by a nut 38. The axiallyextended hub portions 36 of the pistons are formed with openings 32a which are aligned with openings 32 in the shaft extension. Stationary reaction pistons 30 are disposed adjacent the thrust pistons 29 to define chambers 33 therewith, air under pressure tapped from the compressor outlet being supplied to the chambers through the hollow shaft 11 and openings 32 and 32a. The sides of the thrust pistons 29 opposite the pressure chambers 33 communicate with atmosphere through openings 35 in the axially-extending flanges 39 of the reaction pistons, the side of the outermost thrust piston 29 being open directly to atmosphere. The flanges 39 of the reaction pistons are connected together, the innermost reaction piston being secured to stator structure 31. The pressure acting on the thrust pistons 29 counteracts the axial thrust in the direction 28 towards the compressor rotor. When the compressor outlet pressure rises, the piston-type valve 46 opens against the loading of spring 48 whereby air under pressure passes through openings 32b, 32a to the outermost pressure chamber 33a, thereby providing an additional axial thrust in the direction opposed to direction 28. In Fig. 2 the assembly of thrust pistons 29 and reaction pistons 30 is enclosed within a casing 49, the spaces on the sides of the two innermost thrust pistons 29 opposite the pressure chambers 33 communicating therewith through openings 35. The chamber within casing 49 communicates with atmosphere through duct 50 and a valve device which comprises a piston 54 in a cylinder 55. Air under pressure from the compressor outlet acts on the piston 54 against the loading of spring 58 and when the air pressure reaches a certain value the piston 54 and rod 53 move to the position shown in which the duct 50 communicates with atmosphere through ports 57 and 51 when the axial counter-thrust on the pistons 29 is a maximum.

In operation, the cop-feeder B travels along the front of the winder A in a reciprocatory manner and preferably stops at every alternate winding unit in one direction of travel and at the intermediate winding units in the opposite direction of travel. Suitable means are provided for stopping the feeder B. The cops 10 are moved towards the feeder B on a conveyor belt 61 which has means to lift a portion of the belt in the vicinity of a chute 62 which feeds the cops to the feeder B. The cops are receivd in a channel in the section 1, suitable limit switches SW1, SW2 being provided to effect movement of the belt 61. From the channel in the section 1, the cops are individually transferred to channels 27a 27b in the feed-out section whereby the cops drop into slots in a charging holder 30 in the charging section 3. The charging holder 30 is then lowered into the vicinity of the magazine 11 by lifting means 7, the cops being held in the slots by flaps 33. The flaps 33 are then pivoted and the cops drop into the pockets in the magazine 11. In the event of a cop being present in the pocket, the top of the cop prevents the flap from pivoting and the charging cop is held in the charging holder 30. The charging holder 30 is associated with an arcuate guide 80 and means are provided to entrain the holder 30 with the magazine 11 for rotation therewith during charging of the cops. Suitable electric circuits are described for the sequence of operations.
