Abstract: 1317923 Bonded fibre fabrics SANDOZ Ltd 27 July 1970 [28 July 1969 15 Aug 1969 23 Sept 1969] 36356/70 Headings D1B and D1R Non-woven fabrics are impregnated with a mixture of a binder and a pre-dyeing agent, said agent comprising a polyamine or polyamine/amide bearing cationic groupings, produced by cross-linking said polyamines and/or polyamide/amines with acylating or alkylating agents. Then printed, dyed and/or optically brightened. The binder may be a copolymer of 2 or more of acrylonitrile, acrylic acid, methacrylic acid, or their esters of C 1 -C 4  alcohols, butadiene and styrene, and is applied as an aqueous dispersion by spraying, padding or by screen or foam impregnation. The pre-dyeing agent, which is dissolved in the water is formed by reacting polyamines or polyamine/ amides, in which the NH and/or CO groups are linked by linear alkylene chains of 2-8 carbon atoms, optionally carrying methyl, ethyl or phenyl substituents, e.g. dipropylene triamine, or polymerisation products of triethylene tetramine, tetraethylene pentamine, tri-(1,2-propylene)-tetramine, di-(1,3-propylene)- triamine, and di-(1,4-butylene)-triamine with dicarboxyclic acids whose functional groups are linked by a C 4  to C 8  chain, with bifunctional alkylating or acylating agents. These are epichlorohydrin or  were X is 0-7, Z is R 1  and R 2  are alkyl or hydroxyalkyl, Y is a C 2  to C 6  chain, a 2 hydroxy-1,3-propylene radical or (CH 2 ) p -NH-CO-NH-(CH 2 ) p , where p = 2 or 3, and A is an anion, or aliphatic diacyl chlorides. The dispersion may also contain catalysts, and acids, hydroxides or buffers to control the pH value, preferably within 7.5 to 10.5. The fabric may comprise wool, hair, natural cellulose, polyamides, poleysters, polyacrylonitrile, rayon, cellulose diacetate, cellulose triacetate or glass fibres. Impregnation is carried out at 10-50C and condensation at 100-180C. The non-woven fabric is then coloured and/or optically brightened by printing, exhaust dyeing, or pad dyeing by the steam, roll, batch or jig processes by anionic dyes and/or brighteners bearing sulphonic and/or carboxylic acid groups. They are of the acid, direct, solubilized vat, reactive, premetallized and metallizable classes. Examples are given.

Title: Process for the separation of organic compounds
IPC: B01D15/04
Filed: 1956-08-23
Abstract: <PICT:0871493/III/1> In a process, e.g. a chromatographic process, for separating organic compounds from a mixture thereof, by admitting the mixture to a separating column in which an involatile solvent flows in counter-current with an eluent gas, the extraction column is divided into zones each at a constant temperature but the series of zones being operated at different flow rates of eluent gas, solvent, and mixture (1st stage) extracts (at later stages) which are selected so that a component concentrates at the interfaces of each pair of zones, and thee concentrates are drawn off in side streams.  The temperatures in each zone may be the same, increase in successive zones, or one zone may have a temperature gradient applied as described in Specification 871,494.  A column packed with capillary tubes, wire gauze cones or other material to expose a large surface area is divided into 3 zones SC SM SH maintained at successively higher temperatures; an eluent gas enters the column at 1 and leaves the top coolest zone at 2; a solvent liquid is introduced at the top at 3 and passes downwards in stages of increasing temperature and is drawn off at 4.  The mixture is fed in at 5, and sidestreams of extracted components are drawn off at 6 and 7.  In a mixture of 4 components C1 ... C4, flow rates of gas and solvent are adjusted so that components C1 C2 rise in the column and components C3 C4 fall, the temperature of each zone is then adjusted so that C1 rises and is withdrawn with the eluent gas, C2 is drawn off at 6, C4 falls and is withdrawn with the solvent, and C3 is withdrawn at 7.  In an example a mixture of isopentane and n-pentane is separated, using kerosene counter flowing with air at a slow rate, and the mixture fed in at the rate of 9.5 c.c. per hr., the two products are drawn off as side-streams at 6 and 7.  The extraction column may be vertical or inclined.  The solvent liquid includes hydrocarbons, silicones, esters, ketones, ethers, glycols; the eluent gas includes air, hydrogen, CO2, methane and steam.  The process may be applied to separate petroleum hydrocarbons, essential oils, and azeotropic mixtures.

Abstract: 848,724. Photographic developing apparatus. KODAK Ltd. Feb. 24, 1959 [Nov. 25, 1957], No. 36691/57. Class 98(2) The attachment of a film, such as an exposed X-ray film, to a frame on which it is to be supported in a processing bath by impaling the film on spikes projecting from the corners of the frame, is effected in apparatus having dies displaceably mounted in a base-board to receive the spikes, and abutments on the base-board to locate the film and frame so that the latter can be pivoted downwardly in register with the former. Preferably, each die is mounted in a rubber sleeve 21 in base-board 1 having abutments 5, 7 for locating frame 8, 9. The lower end of the die rests loosely in metal ring 12 which is fixed to board 1 and is secured by clip 16. The head of the spike may be larger than the bore 18 of the die so that the spike does not fully enter the bone. The hole punched in the film is then insufficiently large for it to pass readily over the head of the spike but the elastic deformation of the film caused by the concavity 37 ensures that it springs over into the mounted position. In another form the die consists of a hole 35 in a metal plate 32 loosely held by a pin 33 against resilient cushion 36. The plate is arranged inrectangular cavity 30 in board 1.

IPC: C07C5/327
Filed: 1959-10-29
Abstract: Quenching of the hot vaporous effluent from a hydrocarbon dehydrogenation reaction is effected by pre-quenching by direct contact with a first supply of quench oil, introducing the liquid and vaporous effluent therefrom into a main quench zone where it is contacted in countercurrent with a cool, descending, second supply of quench oil, accumulating both pre-quench and main quench oils in the bottom of the main quench zone, recycling a first part to the pre-quench zone, cooling a second part after removing a minor portion and recycling the cooled oil to the main quench zone, heating the minor part and vaporising at least half by volume to separate a higher boiling portion as liquid which is removed and passing the vapours into the main quench zone.  The vapours to be quenched may be from the dehydrogenation of C3-C5 hydrocarbons containing olefines and (or diolefines.  They are quenched with an aromatic oil, e.g. a catalytically cracked oil boiling in the range 350-600 DEG  F. and containing at least 65% aromatics.  It is collected in the bottom of the main quench zone in two compartments, one collecting the pre-quench oil which is recycled to the main quench zone, the other the main quench oil to be recycled to the pre-quench zone.

Title: A process for the production of barium hydroxide
Inventor: MARSHALL JOHN GEOFFREY
IPC: B01J47/00
Filed: 1960-10-26
Abstract: Barium hydroxide is produced by passing a solution of barium sulphide through either a strongly acidic cation-exchange resin in the sodium or potassium form or a strongly basic anion-exchange resin in the hydroxyl form. The effluent is collected, in the case of the anion-exchange resin this is barium hydroxide and in the case of the cation exchange resin the effiuent is sodium sulphide. The exchange resin is then regenerated by passing sufficient sodium or potassium hydroxide solution through the resin in the reverse direction of flow.  The effluent from the regenerating step in the case of the cation-exchange resin is barium hydroxide and in the case of the anion exchange resin is sodium sulphide. The barium sulphide solution, which is employed at a temperature of 50-70 DEG  C., may comprise the aqueous extract of the clinker produced by the coke or like reduction of barytes.

Title: Improvements in or relating to Feed apparatus for Copying Machines
IPC: B41L7/04
Filed: 1966-08-18
Abstract: 1,158,002. Feeding sheets. RICOH K.K. 18 Aug., 1966 [21 Aug., 1965], No. 37006/66. Heading B8R. A feed apparatus for a document copying machine comprises a signal device 20, responsive to the receipt of an original document, means for supplying copy sheets 13, sheet by sheet to a copying section P of the machine, means defining a channel for the passage of the document to the copying section and means coupling with the signal device a control of the copying section capable of varying the velocity of the document and sheet through the section, the signal device being adjustable through the coupling means by the control means in accordance with said velocity to vary the moment at which it actuates the supplying means on receipt of a document whereby a sheet is delivered with the document to the copying section either with the leading edges co-incident or at a preset spacing from one another. In a preferred embodiment, Fig. 1, there is provided a mouth 1 for original documents on endless conveyer 2 for documents and a guide plate 5. Endless conveyer 8 serves to transport sensitized paper from file 13 supported on vertically displaceable stacker 14. Guide rollers 18, 19 are provided where the leading edges of document and paper meet immediately before a printing or exposure section P. An automatic document and sensitized paper separating device S leads to developing section D. The separated document may be returned to 1. Micro-switch 20 is movable in the directions indicated by the arrows on rack 22. A pinion 21 meshing with rack 22 is coupled with an exposure speed control member (not shown) of the exposure section which varies the speed of travel of the original and the sensitized paper. The microswitch may alternatively be moved by a cam device coupled to the exposure speed control. The leading edge of a document actuates the micro-switch which in turn causes arm 17 to move roller 16 into contact with a sheet 13 which sheet is delivered to the conveyer. Since the time at which this actuation occurs is determined by the position of micro-switch 20 which is in turn determined by the speed of travel set for the original document the ends of the document and paper will always assume a constant relative position to each other irrespective of the set exposure speed. Instead of a movable micro-switch three micro-switches in different positions, e.g. 20, 20<SP>1</SP> and 20<SP>11</SP> may be provided only one of which is activated for a given exposure speed. Alternatively a photoelectric cell may replace the micro-switch.
