Title: Improved means for Delivering Measured Quantities of Semi-Liquid or Pasty Materials
Inventor: WEBSTER EDWARD
IPC: B65B3/32
Filed: 1967-03-31
Abstract: 1,151,461. Reciprocating pumps; syringes. EDWARD WEBSTER Ltd. Feb. 19, 1968 [March 31, 1967], No.14814/67. Headings F1A and F1R. A pump for dispensing adjustable measured quantities of semi-liquid material, e. g. mascara, into containers, comprises a cylinder 31, Fig. 3 with an inlet port 29 connected to a supply container 10, Fig. 2, with a compressed air-actuated piston 18, and an outlet port 44 connected to a containerreceiving nozzle 45, a piston 32 being reciprocated in cylinder 31 by a double-acting compressed air motor and having a piston-rod 35 slidably extending through a piston 36 and carrying an axiallyadjustable, threaded sleeve 41. Adjustment of sleeve 41 by wheel 39 determines the axial spacing between pistons 32 and 36, and hence the quantity discharged. In the left-hand position of the pistons shown, the space between the pistons is filled with material through the inlet port, the piston assembly then being moved to the right to close the inlet port and open the outlet port. Piston 36 abuts plate 37 at the end of its movement to the right, the continued rightward movement of piston 32 discharging the material through outlet port 44. The supply container 10 is filled by releasing nuts 15, and removing cover 14 and the piston assembly. On replacing the piston assembly, trapped air is vented through piston-rod 21 and a vent valve, Fig. 1 (not shown). When the container is nearly empty, a collar 25 on piston-rod 21 actuates a switch 26 controlling a solenoid valve to shut-off the compressed air supply to the space above piston 18. Reciprocation of the air motor driving the pump is controlled by a pedal-operated air valve. A pair of pump assemblies is mounted on a stand with a common air supply.

Abstract: Unspecified types of dyes, dyeing with; cellulose esters or ethers; dyeing; textile materials, treating with liquids; dye preparations; cellulose carboxylates and ethers.--The fastness of colourations, produced with anthraquinone dyestuffs on textile materials or materials made of or containing cellulose or cellulose esters or ethers, including cellulose ester or ether films, filaments, threads or fabrics, is improved by incorporating in the materials, before, during or after their colouration, bases of the general formula-- <FORM:0361362/IV/1> in which R is an aralkyl group, R1 is an aromatic residue, and R2 is hydrogen or an organic residue, such bases taking no part in the production of colouring matter on the materials. The amount of the base incorporated is preferably 0,5-2 per cent based on the weight of the material, and the use of such large amounts as are necessary to prevent slipping, splitting or laddering in woven or knitted fabrics (cf. Specification 280,990, [Class 2 (ii), Cellulose &c.]) is excluded.  Specified bases are benzylethylaniline, benzylmethylaniline and their homologues and nuclear substitution products.  Other substances capable of improving the fastness, such as the ureas, thioureas, and guanidines of Specification 340,572 or the compounds of Specification 340,541, and/or compounds having an alkaline reaction due to an inorganic base, such as sodium carbonate, borax, disodium hydrogen phosphate, sodium acetate, sodium palmitate or sodium oleate, may be incorporated separately from or simultaneously with the aralkylated aromatic base.  The bases may be applied in the form of aqueous solutions of the bases or their salts or in the form of aqueous dispersions produced, for example, by the methods of Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, 273,820, 322,737, or 323,788, [all in Class 2 (iii), Dyes &c.].  In the application to artificial materials, particularly materials made of or containing cellulose esters or ethers, the base may be incorporated in the spinning solutions used. The invention is particularly applicable to the dyeing of cellulose ester or ether materials with amino, alkylamino or arylamino derivatives of anthraquinone.  In an example a cellulose acetate woven fabric is dyed a blue fast to the combined action of light and acid fumes by treatment at 80 DEG  C. in a bath containing soap, a dispersion of 1 : 4-di-(methylamino)-anthraquinone in turkey red oil, and a dispersion of benzylethylaniline in turkey red oil, following by rinsing, passing through a solution of borax, and drying.
