Patent GB-808668-A (GB)
Title: Detergent compositions
IPC: B01J2/00
Filed: 1957-04-01
Abstract: A minor proportion of a granular detergent composition consists of coloured granules uniformly distributed throughout the composition, the colouring of the coloured granules being vivid so as to be sharply contrasted with the background coloration of the remaining bulk of the granules.  The coloured granules suitably constitute 2-30 per cent of the composition, are generally 0.2-1.5 mm. in their largest dimension, and may comprise granules of more than one colour. As shown, an apparatus suitable for the production of such compositions comprises an air lift 3 into which the uncoloured detergent composition is fed by conveyer 1. Particles <PICT:0808668/III/1> which are too small are not transferred by gravity separator 4 to conduit 6 but pass out through 5, while lumps which are too large fall into container 2.  The particles of the required size pass over vibrating screen 7 and thence to conduit 10, where a proportion of the material is diverted by means of conduit 16. The remainder of the material passes from conduit 10a to conveyer 12 prior to packaging.  The diverted material passes ultimately to rotating drum 18, where it is sprayed with colouring material supplied from source 19, before passing back to air lift 3, by means of conduit 23, where it is intimately mixed with the uncoloured material.  If multi-coloured compositions are required, separate units as described may be used for each colour required, all the units having an air lift in common for mixing. The detergent compositions described comprise tallow soap, sodium dodecylbenzene sulphonate, sodium tripolyphosphate, sulphate, and silicate, miscellaneous solids, anticaking agents, sudsing control agents, and substantive fluorescent dyes.  Suitable non-substantive dyes for colouring the compositions include Erioglaucine, Patent Blue A, Rhodamine B, Amaranth Red, Fast Crimson, Wool Violet, Azure Blue, and Lumogen Yellow, Blue, and Green.

A reel stand comprises a first pair of spaced arms 3 supporting a working reel 5; a second pair of spaced arms 4 supporting a replacement reel 6; a common shaft 2 about which the arms 3, 4 can pivot under the action of hydraulic jacks 7; and a pivotable arm 10 carrying a guide roller 12 associated with a web-cutting and splicing device 11. In use, when the reel 5 is almost exhausted, the arm 10 is moved into position 15 and the reel 6 is accelerated so that the splicing of the new web to the running web can be effected by the device 11 which then severs the old web so that the spent reel can be removed from the arms 3 (Figs. 5 to 8, not shown); the empty arms 3 are then pivoted in a clockwise direction into an approximately horizontal position where they can be loaded with another spare reel and the arms 4 are pivoted anticlockwise so that the reel 6 is moved into the working position (Fig. 9, not shown), the arms 3 and 4 moving past each other during this operation. When reel 6 is itself exhausted a similar change-over sequence is effected (Figs. 10 to 13, not shown), so that the arms 3 and 4 again occupy the position shown in Fig. 1. The arms 3 are preferably longer than the arms 4, and the arms may be mounted on separate shafts (Figs. 3 and 4, not shown).

Title: Improvements in or relating to producing foam for fire extinguishing purposes
IPC: A62D1/06
Filed: 1926-04-23
Abstract: 274,567. Excelsior Feuerl÷schgerate Akt.-Ges., and Wagener, C. April 23, 1926. Fire-extinguishing by foam; chemicals. - In the production of foam for fire-extinguishing, reaction chemicals are used, one of which at least is insoluble in water. A suspension of the insoluble chemical may be produced by the addition of water under pressure which is subsequently brought into contact with the soluble chemical by the stream of water under compression. The method may equallv well be carried out by dissolving the soluble chemical, then bringing the solution into contact with the insoluble chemical. In a preferred method, the insoluble chemical such as carbonate or bicarbonate of calcium or magnesium, is mixed into a paste with a little water, and the foam generating substance is added to the paste. To this paste is then conducted the solution of a soluble chemical, such as oxalic acid, by a stream of water under pressure. When a soluble salt has been kept as a dry powder for use in producing foam, it has been found that its solubility has varied, and the production of foam has been irregular.

Inventor: ACH RENE
IPC: A63H15/02
Filed: 1967-03-08
Abstract: 1,169,116. Walking or waltzing puppet. R. ACH. 20 Feb., 1968 [8 March, 1967], No. 10846/67. Heading A6S. A walking or waltzing puppet has two feet 13, 14 rotatably mounted on the legs, the axes of rotation of the feet converging in a direction away from the feet towards the body. The C.G. may lie on or adjacent the bisector of the angle formed by the axes of rotation of the feet, whereby displacement of the C.G. in a direction parallel to the line interconnecting the feet transfers the weight of the puppet from one foot to another. This displacement may be achieved by placing the puppet on an incline, by pulling with a string or by rotating the feet using an electric or clockwork motor and having a weight or weights mounted on the feet or on the body in connection with the motor. When manual displacement is used the feet should be circular, but the feet may be otherwise shaped, e.g. trapezoidal on motor operated puppets. The feet may be rotated in the same or opposite directions.

Title: Process for the bleaching and shrinkproofing of wool
IPC: D06L4/30
Filed: 1960-03-28
Abstract: Wool is bleached and shrink-proofed by introducing and submerging it in water, the water and the resulting treating bath being at 13 DEG -25 DEG C., introducing progressively a dilute aqueous solution of an acid with continuous agitation until a pH of 2-4,5 is reached, con-tinuing agitation, introducing slowly an aqueous chlorite solution of pH 8-9 and free from ClO2 until the wool turns pink whereby the pH of the chlorite solution is lowered without evolution of ClO2 and the bath remains sub-stantially colourless throughout the treatment, rinsing with water and treating the pink wool with an aqueous reducing solution at a tempera-ture of 45 DEG -60 DEG C.  The acid may be phosphoric, sulphuric, formic or acetic acid and may be in the form of a dilute aqueous solution having a concentration of 5-20% by weight. When acetic acid is used 5-40% of sodium acetate based on the weight of the undiluted acid may be added to the solution to serve as a buffer at the indicated pH.  The chlorite solution may be an aqueous solution of an alkali metal chlorite having a concentration of 5-20% by weight and the reducing solution may be a 0,2-1,5% by weight aqueous solution of an alkali metal bisulphite or hydrosulphite or a mixture thereof.  The treating bath and bleaching solution may also contain 0,02-0,1% by weight of a wetting agent, e.g. RCOOCH2CH2SO3Na, RCONHCH2CH2SO3Na, RCH2SO4Na or RCH2SO3Na in which R is an alkyl or alkenyl radical containing 12-20 carbon atoms, an alkyl aryl sulphonate, an alkyl p  phosphate salt, lauryl polyethoxy ether or n-octadecyl diso-dium sulphosuccinamate, and 0,005-0,05% by weight of hydroquinone may be added to the acidic chlorite treating bath.  The treatment may be combined with an additional chlorina-tion treatment with a sodium hypochlorite solution followed by treatment with sodium hydrosulphite solution or with a treatment with a proteolytic enzyme, e.g. papain or trypsin, which may be added to the reducing solution together with 0,2-1% by weight of sodium bicarbonate.
