Filed: 1946-08-29
Abstract: 632,797. Self-feeding mops. SMITH, A. W. Aug. 29, 1946, No. 25991. [Class 19] A mop of the kind comprising a head, a handle and a cylinder connected with the handle for containing a floor-treating medium, is characterised by a delivery tube supported by the cylinder, means associated with said tube for attachment thereto of the head, a plunger mounted on said delivery tube and displaceable within the cylinder by movement of the handle relative to said attachment means and latch means movable with the handle to effect said displacement of the plunger, the latch means being withdrawable from its effective position to enable free restoration of the plunger to its initial position. In the Figures, the mop comprises a handle 1 and a head 2 which may be reversible to provide a polishing surface and a scrubbing surface respectively. The handle is connected with an extrusion device 4 which consists of a cylinder 5 containing a plunger or piston 6, the rod 7 of which is hollow and is engaged by a half-nut 8 at the base of the cylinder. The rod 7 which constitutes the delivery tube is slidably guided in a tube 9 protruding from the lower end of the cylinder and is attached to the mop head so that by rotating the handle 1 and cylinder 5 the piston may be caused to travel up the cylinder to feed the contents to the floor or mop surface. The handle is releasably connected to the cylinder and the mop head 2 is pivoted to the rod 7 by means of a disc 11 fixed to the rod and formed with a continuation 13 of the conduit 10. The device may be filled by screwing the piston head down, but preferably the half-nut 8 is slidably mounted in the bottom of the cylinder so that by pressure on a knob 18 the half-nut may be released from engagement with the piston-rod and the latter slid down through the tube 9. The half-nut is biassed to the engaging position by a spring 19. The polishing medium may be loaded directly into the cylinder 5 after removing the handle, or a refill cartridge 20 may be used, being fitted into the cylinder 5 with its open mouth downwards.

Title: Improvements in or relating to the preparation of vat-dyebaths
IPC: D06P1/22
Filed: 1933-09-28
Abstract: Vat dyes, dyeing with.--A vat dyebath for cotton is prepared by dissolving in water two solid preparations, viz. (a) a mixture of 1 molecular proportion of sodium hydrosulphite with about 2 molecular proportions of caustic alkali (or an equivalent quantity of another substance of alkaline reaction) and (b) a mixture of the vat dyestuff, alkali and hydrosulphite in proportions determined empirically in the case of each dyestuff as described below, preparation (a) being used in a quantity per unit volume of dyebath necessary for vatting and maintaining in solution the quantity of the particular dyestuff present in (b) sufficing to produce the lightest dyeing and preparation (b) being used in a quantity per unit volume of dyebath necessary to produce the desired depth of the dyeing.  To determine the proportions of the ingredients in preparation (b) the known prescriptions for dyeing cotton with the particular dyestuff are utilized, the optimum quantities of alkali and hydrosulphite required to produce the lightest dyeings and dyeings of medium depth are noted and, with these as absciss  and the percentages of dyestuff as ordinates, straight lines are drawn inclined to the absciss  at angles of which the tangents represent the ratios percentage of dyestuff/quantity of alkali and percentage of dyestuff/quantity of hydrosulphite over the whole range of dyeings; these ratios correspond to the required proportions in preparation (b). Preparation (a) may be stabilized by an admixture, e.g. of starch or lycopodium powder.  The following examples are specified: (1) Cotton yarn is dyed by treatment for \ba1/2\be hour in a vat at 50 DEG  C. primed with 7 grams per litre of a mixture of hydrosulphite (1 mol.) and caustic soda (2 mols.) with the addition of 1\ba3/7\be grams per litre of a mixture containing 25 per cent of the dyestuff 3 : 3<1> - dichloro - N - dihydro - 1 : 2 : 1<1> : 2<1\h - anthraquinoneazine, 45 pe>r cent of caustic soda and 30 per cent of hydrosulphite and developing as usual. (2) Cotton yarn is similarly dyed in a vat primed as in (1) with the addition of 0,5 per cent of the same dyestuff preparation. (3) Cotton muslin is dyed on the jig by treatment in four passages in a vat liquor primed with 3 grams per litre of the hydrosulphite-caustic soda mixture with the addition of 2 per cent of a mixture containing 30 per cent of the dyestuff obtainable by condensing 1-amino-5-benzoylaminoanthraquinone (2 mols.) with oxalyl chloride (1 mol.), 30 per cent of caustic soda and 40 per cent of hydrosulphite and developing as usual.  (4) Cotton cheeses are dyed by treatment in a vat liquor at about 45 DEG  C. primed with 3 grams per litre of the hydrosulphite-caustic soda mixture with the addition of 8 per cent of a mixture containing 30 per cent of the dyestuff di-p-aminobenzoyl-1 : 4-diaminoanthraquinone, 30 per cent of caustic soda and 40 per cent of hydrosulphite.  (5) Slivers are dyed by treatment in a vat liquor at 25 DEG  C. primed as in (4) with the addition of 0,5 per cent of the dyestuff mixture in (4).

Patent GB-268806-A (GB)
Abstract: 268,806. Posternak S., and Posternak, T. March 31, 1926, [Convention date]. Albumenoids.-The mixture of acid bodies containing phosphorus obtained from de-fatted and coagulated egg-yolk is separated into three constituent bodies (termed a, #, and gamma) by treating a solution of the alkali salts with alcohol to precipitate the alkali salt of the # body, then adding a soluble alkaline earth salt to precipitate the alkaline earth salt of the a body, and then precipitating the alkaline earth salt of the y body by means of alcohol or a heavy metal salt; in the latter case, the heavy metal salt of the gamma body thus formed is decomposed to the free -y body or its alkali salt by adding a hydrogen or alkali compound the anion of which forms an insoluble heavy metal salt. In an example, a solution of the sodium salts of the mixed a, # and gamma bodies made according to Specification 268,805 is treated with alcohol while stirring, when a flocculent precipitate of the sodium salt of the # body is formed. It mav be treated with suitable salts to give the corresponding alkaline earth or heavy metal salts. The filtrate, freed from alcohol by distillation in vacuo, is treated with calcium chloride or acetate, when the calcium salt of the a body is precipitated. It may be treated with sodium oxalate to obtain the sodium salt, which may be converted into the alkaline earth or heavy metal salts. The filtrate from the a body is precipitated with alcohol to obtain the calcium salt of the gamma body, or with lead acetate, the lead salt obtained being decomposed with sulphuretted hydrogen to give the free gamma body, or with a copper, mercury or other heavy metal salt. In another example, the solution of the mixed sodium salts is saturated with sodium chloride and hydrochloric acid is added. The precipitate, containing the a and # bodies, is dissolved in sodium carbonate solution and mixed with alcohol while stirring. The precipitate contains the body #. The filtrate is freed from alcohol and treated with an alkaline earth salt to precipitate the alkaline earth salt of the body a. or is poured into alcohol acidified with hydrochloric acid to precipitate the body a in the free state. Specification 221,716 also is referred to.
