Title: Process for separating olefinic hydrocarbons from hydrocarbon mixtures
IPC: C07C7/11
Filed: 1957-05-17
Abstract: Olefines are separated from gaseous or liquid mixtures containing hydrocarbons by using as solvent for the olefine an aqueous solution of silver fluoroborate and/or fluorosilicate. Gaseous mixtures may contain other gases such as carbon dioxide, carbon monoxide, oxygen, hydrogen, nitrogen or an inert gas.  Up to 1% of acetylene may also be present.  The silver salts can be used in concentrations exceeding 1 kilogram of silver per litre. Space-time yields of about 100 litres of olefine gas per litre of absorption space per hour can be obtained, the olefine being readily regenerated by heating the solution.  In cyclic processes water is added to the silver salt solution prior to recycling to the absorption stage to replace water lost by evaporation in regenerating the olefine and the solution is filtered to remove silver acetylide which may be formed.  The examples illustrate (1) the recovery of ethylene in 99,9% purity from a gaseous commercial ethylene containing 94,1% ethylene with carbon dioxide, hydrogen, ethane and small quantities of acetylene, oxygen and nitrogen (2) the separation of gaseous ethane and ethylene (3) the recovery of ethylene from a gaseous mixture with methane, hydrogen and carbon monoxide (4) the separation of gaseous propane and propylene (5) the separation of liquid propane and propylene, all using aqueous silver fluoroborate solutions.ALSO:Olefines are separated from gaseous mixtures containing hydrocarbons by using as solvent for the olefine an aqueous solution of silver fluoroborate and/or fluorosilicate.

Title: Process for the manufacture of vat dyestuffs
IPC: C09B1/42
Filed: 1936-06-05
Abstract: Vat dyes are made by reacting a cyclic amino compound containing at least one hydrogen atom attached to the nitrogen with excess over the molecular amount of an aromatic dicarboxylic acid halogenide, isolating the reaction product and causing it to react with another amino compound containing at least one hydrogen attached to nitrogen, at least one of the cyclic amino compounds being capable of being vatted.  The first stage and/or the second stage may be performed in presence of a high-boiling solvent, or the first stage may be carried out with a high-boiling solvent and with an acid-binding agent, in which latter case the use of excess of the dicarboxylic acid halogenide and the isolation of the intermediate product may be dispensed with.  The first stage is performed below 100 DEG  C. and the second above 100 DEG  C.  Dicarboxylic acid halogenides specified are those of terephthalic, isophthalic, diphenyldicarboxylic and naphthalene dicarboxylic acids.  Amines capable of being vatted are amino compounds of anthraquinones and higher ring systems such as benzanthrones, anthanthrones, violanthrones and anthrapyridine.  The new dyes have good fastness properties and are suitable for printing. In examples, (1) excess isophthaloyl chloride or terephthaloyl chloride is reacted with 1-aminoanthraquinone, followed by 1-amino-5-benzoylaminoanthraquinone; (2) excess isophthaloyl chloride is reacted with 1-amino-5-benzoylaminoanthraquinone followed by 1-amino-4-benzoylaminoanthraquinone (orange shades on cotton) or monoaminoanthranthrone; (3) isophthaloyl chloride, or (4) terephthaloyl chloride, is reacted with 1-amino-5-benzoylaminoanthraquinone in presence of pyridine, followed by 1-aminoanthraquinone without isolation; in (3) above, the amino-anthraquinones may be reacted in the reverse order, the pyridine may be replaced by collidine, quinoline, or dimethylaniline, and the solvent may be di- or tri-chlorbenzene instead of nitrobenzene; (5) isophthaloyl chloride or terephthaloyl chloride is reacted with 1-aminoanthraquinone, followed by 4-aminopyrimidine; in (5) above, one amino compound may be replaced by 5-aminopyrimidine; isophthaloyl chloride is reacted with 1-amino-5-benzoylaminoanthraquinone, followed by (6) 1-amino-4-methoxyanthraquinone, (7) monoaminopyrene (bordeaux-red shades on cotton), (8) b -naphthylamine, (9) piperidine, (10) 1-amino-6-chloranthraquinone, (11) naphthalene-1.4-dicarboxylic acid chloride is reacted with 1-amino-5-benzoylaminoanthraquinone, followed by 1-amino-4-benzoylaminoanthraquinone.  Specification 27098/08, [Class 2], is referred to.

Title: Apparatus for feeding and discharge of sheets or forms
IPC: G06K13/08
Filed: 1958-05-19
Abstract: 860,971. Feeding and delivering sheets. KOOPERATIVA FORBUNDET EKONOMISK FORENING. May 19, 1958 [May 18, 1957], No. 16020/58. Class 100(1) Feeding sheets:-In a data processing machine in which sheets are separated sequentially from the bottom of a pile in a holder, passed through the machine, and stacked beneath a pile in a second holder, the first holder 2 has a base 10 which does not extend to the front wall 9 thereof so that the front end of the pile 3 is exposed, and the front end of the bottom sheet is deflected downwardly from the holder by a curved plate 11, which has a slot 12 therein connected to a source of vacuum, into contact with two driven perforated suction drums 13 arranged one on each side of the plate 11 and adapted to separate the sheet from the pile 3. The suction drums have pairs of peripheral perforations spaced apart to suit the sheet lengths. Sheet separation is assisted by air blasts through openings 19 in the side walls of the holder 2, and adjustable air blasts from pipes &c. 20 at the front of the pile. The front wall 9 of the holder is pivoted at the top about a pin 8, and is forced against the pile 3 by a hammer 17, pivoted at 16, which is actuated during each sheet separation to force the rest of the pile against rear supports 7. Friction between the bottom sheet and the base 10 is reduced by providing ribs 15 on the base. The separated sheet is fed over the base of a guiding device 4 by the drums 13 and is engaged by a driven endless belt 26 arranged on two pulleys which are not in alignment, whereby the sheet is forced against a side registering plate 21. The pressure exerted by the belt on the sheet is adjusted by presser rollers 30, 31. The sheet is then fed through the machine (not shown) along a path 5 by suction rollers (not shown). Sheet delivery:-The processed sheets are delivered along the path 5 on to two spaced conveyer belts 36 which move them into the base of a holder 6 provided with four sheet elevating screws such as 45, 47, two at each side, which are rotated about their vertical axes, and place each sheet beneath the bottom of a pile 3<SP>1</SP>. The direction of rotation of these screws is such that the sheets are stretched during elevation. If the weight of the pile 31 is such that sheets are prevented from entering the holder 6, or a stoppage is caused for any reason, the sheets cause the belts 36 to sag into contact with a roller 48 which is then rotated by the belts: rotation of the roller 48 actuates an arm 49 which operates a switch 50 to stop the motor driving the belts 36.

Abstract: 485,246. Artificial legs. SOKAL, S. (Instituto Ortopedico Rizzoli) June 9, 1937, No. 16044. [Class 81 (ii)] Relates to an hydraulic device for locking the articulation of the knee in the flexing direction. A cylinder 1 containing oil is hing- ed to the " shin " at 2<1> near the angle, and a piston 7, connected by a part 12 and hinge 13 to the lower part of the " thigh," sides therein on bending or straightening the knee, the oil passing through passages in the piston. A strap consisting of elastic and inelastic parts 22<1>, 22, attached to the wearer's belt 23 and running over a guide 19 on the part 12, is connected to a spindle 9 carrying a valve 25 pressed towards open position by a spring 33. When the wearer leans forward, either deliberately, or instinctively in regaining balance lost by stepping on the bended knee, tension on strap 22<1> closes valve 25 to lock the piston, allowing the whole weight to be supported. The knee may however be straightened, with valve 25 still closed by the tension on strap 22, piston 7 then moving upwards and oil passing through a flap valve 30 carried on valve 25, which valve 30 normally covers ports in valve 25.
