Title: The manufacture of substantive dyestuffs
IPC: C09B56/06
Filed: 1934-04-13
Abstract: Substantive stilbene dyes are made by condensing in the presence of alkali a nitrostilbene compound of the general formula <FORM:0430596/IV/1> with an aminostilbene compound of the general formula <FORM:0430596/IV/2> (in which formulae X and Y = nitro or arylazo groups or one stands for an arylazo and the other for an arylazoxy group, with the exception that X and Y must not both be arylazo groups).  They may be after-treated by methods customary in the manufacture of azo and stilbene dyes, e.g. oxidation, reduction, alkylation and formation of metallic complexes and yield clear fast reddish yellow to reddish orange shades.  In examples (1)--(3)4 - nitro - 4<1> - aminostilbene - 2 : 2<1> - disulphoacid is condensed in aqueous caustic soda with 4 : 4<1> - dinitrostilbene - 2 : 2<1> - disulphoacid, dinitroazodistilbenetetrasulphonic acid (formula given) or the methylated azo dye 4 - nitro - 4<1> - aminostilbene - 2 : 2<1> - disulpho acid --> phenol; the first compound may be after-treated with hypochlorite; (4) the methylated and reduced dyestuff 4 - nitro - 4<1> - aminostilbene - 2 : 2<1> - disulphonic acid --> phenol is condensed with 4 : 4<1> - dinitrostilbene-2 : 2<1> - disulphonic acid.  The Specification as open to inspection under Sect. 91 states that X and Y in the above formulae must not be the same arylazo group and gives an example in which 4-nitro-4<1>-aminostilbene - 2 : 2<1> - disulpho acid is condensed with the dyestuff obtained by reduction of 4 : 4<1> - dinitrostilbene - 2 : 2<1> - disulpho acid with glucose or formaldehyde.  This subject-matter does not appear in the Specification as accepted.  A sample has been furnished under Sect. 2 (5) of the dyestuff obtained by condensing 4-nitro-4<1> - aminostilbene - 2 : 2<1> - disulphonic acid with not more than equimolecular proportions of aniline and condensing the intermediate product with the methylated azo dye 4 - nitro - 4<1> - aminostilbene - 2 : 2<1> - disulphonic acid --> phenol (formula given).

Title: Apparatus for placing tube stock mounted valves on aerosol containers
IPC: F17C13/04
Filed: 1969-03-05
Abstract: 1,223,093. Making aerosol containers. COSTER TECHNOLOGIE SOECIALI S.p.A. 5 March, 1969 [28 March, 1968], No. 11577/69. Heading B3A. An apparatus for placing valve assemblies on to aerosol containers 2, comprises a container support platform 1, a tapered guide funnel, the smaller end of which is resiliently deformable and a tube stock inserting device including a tubular body 10, an elongate body 13 movable therein, the end of the body 13 facing the platform 1 providing a seat for the valve assembly, which seat communicates with a source of vacuum. The apparatus rotates about a vertical axis whereby it is taken to a series of work stations and at the first a fixed cam engages an arm 9 to lower the device so that it can pick up a valve assembly from a guide (42), Fig. 2 (not shown). At the next station the arm 9 is clear of the cam and the device 4 is raised. At the third station a cam 44 actuates a valve 27 to supply compressed air via a tube 29 to a cavity 20. Compressed air is also supplied to a cavity 18 via a tube 26 but the upper surface of the piston 12 is of greater area than that of the lower surface. The air passes through apertures in a piston 17 to act on the piston 12 thereby driving the body 10 downwardly. The body 10 is so dimen. sioned that the end of the tube 16 lies within the limits of the funnel and as it descends the body actuates a valve 30 whereby compressed air is supplied to a chamber 23 to drive the body 13 downwardly. The lower end 14 of the body pushes the valve assembly through the funnel, the plates 6 of which pivot against the action of springs 7 and then close back over the valve. Movement to the next station brings the cam 44 clear of the valve 27, venting tubes 29, 31 to the atmosphere and causing the pistons 12, 17 to move upwardly by the action of the pressure in the cavity 18, the chamber 23 being vented through the valve 27. The plates 6 retain the valve assembly on the container 1. When the body 10 clears the valve 30, the chamber 23 is vented to the atmosphere therethrough. In an alternative embodiment the tubular body and the elongate body are moved individually by fluid pressure-operated cylinders (52), (56), Fig. 9 (not shown), and there is no equivalent of the hollow cylinder 8.

Abstract: 857,517. Tea extracts. UNILEVER Ltd. April 9, 1957 [April 9, 1956], No. 11628/57. Class 129 In a multistage equilibrium batchwise counter current process for producing a tea extract, fresh leaves are introduced at the initial stage and fresh water at the final stage, in the proportion of between about 9:1 and 13:1, the initial and final stages being maintained at below about 80 ‹C. and above about 90 ‹C. an extract, having at least about 2À5 % soluble tea solids representing about 80 % of the tea solids in the leaves, being withdrawn from the initial stage. As shown in Fig. 1, in a two cell process, fresh leaves are introduced to the first cell 10 at 17 and an extract enters from pipe 20 having come through cooler 16 from the second cell 11. The extractors may be jacketed covered kettles with a central rotating agitator having blades extending adjacent the interior walls. The fresh leaves and extract are stirred until equilibrium is achieved between the dissolved and undissolved components of the leaves the temperature being held below 80‹C. after which the extract is drained through pipe 21. The leaves are removed and squeezed in press 12 to remove further extract which passes through pipe 22 and is combined with the extract leaving the first cell through pipe 21. The pressed leaves are added to cell 11 which is supplied with hot water through pipe 26. The temperature in this cell is maintained at above 90 ‹C. and the mixture is again stirred until equilibrium is achieved when the extractor is drained through pipe 20 to cell 10 and the leaves are removed and pressed in press 15 and then discarded. The extract from pipe 21 is concentrated to produce a tea extract which will, on dilution, produce tea beverage. In a modification, Fig. 2 (not shown) three cells are used, the central cell receiving pressed leaves from the first cell and extract from the third cell and from the press beyond the third cell and the process being generally similar to that shown in Fig. 1. Instead of pressing the leaves between extractions, a larger number of steps, e.g. five, may be used, Fig. 3 (not shown) the tea leaves being transferred through a perforated reel, over a shaker screen or through a pulper or an auger type juice extractor. The extract removed from this process is concentrated e.g. as described in Specification 853,834. Non- sweet corn syrup may be added and the mixture is dried e.g. by spray drying. Examples are given using various black teas and blends thereof in the above processes. Specification 844,451 also is referred to.

A sound head H associated with each film feeds a loud-speaker H1 or H2 through an amplifier A. Multiple loudspeakers may be fed from multiple sound tracks in a separate sound reproducer. A flying spot scanner for each film comprises a scanning tube T imaged by a lens L1 on the film behind which a field lens L2 concentrates the light on a photo-cell P, the output of which, amplified by the amplifier V, is fed to the projection tube K from which an image is projected optically by a concave mirror U with correcting plate Z. The deflection generators Q, J for the scanning and projection tubes, together with the motor M, are driven in synchronism by a signal generator R. Both films may be scanned by single tube T by interposing an optical beam splitter after the lens L1. For scanning colour film a beamsplitter is interposed between the film and separate photo-cells P for recording different colour aspects. Different image records may be carried on a single film. The picture records may be magnetic instead of photographic.
