Patent GB-634222-A (GB)
Title: Improvements relating to closure devices for bottles and the like
IPC: B65D47/24
Filed: 1947-05-28
Abstract: 634,222. Stoppers. LEVIN, D. May 28, 1947, No: 14241. [Class 125 (iii)] A closure device for a bottle or like container comprises an inner plug member, which fits in the container mouth, and an outer rotatable cap member, both members having liquid discharge apertures. When the cap is rotated it closes at least one liquid aperture and is displaced axially to bring complementary surfaces on the cap and plug into tight sealing engagement. A projecting cylindrical portion of the plug co-operates with a complementary cylindrical inner surface of the cap to form a rotatable mounting for the cap and also provide a liquid-tight seal between cap and plug. In the form shown in Fig. 2, for sprinkling, an inner resilient plug 11 fits in the bottle neck, and a threaded cap 15 screws on to the bottle neck. Liquid is dispensed via bore 19 which may be lined with a rigid tube 20, and bore 21, the cylindrical walls of members 11 and 15 being in liquidtight contact. When cap 15 is screwed down, surfaces 18 and 14 engage to seal bores 20, 21. Instead of screwing on to the bottle neck, cap 15 may screw on to the plug or a ferrule thereon. A number of eccentric bores such as 20 may be provided and the upper' surface of the plug may be so shaped that the bore in the cap is sealed before the bore or bores in the plug, to facilitate the return to the bottle of liquid trapped between cap and plug. Upward movement of the cap may be limited by turning in the lower edge of the cap below a flange on the plug, as below the ferrule. In another form, Fig 3, for steady pouring, liquid outlet passages 25, 30 and air inlet passages 26, 31 are provided, the air inlet tube projecting at 27. A slight rotation of the cap moves the inlet and outlet passages out of register and also forces surfaces 24, 29, which are never separated, into closer sealing contact. Relative rotation of cap and plug is limited by engagement of a stepped portion of the screw threads on ferrule 32 with an interruption in the screw threads on the cap. In the form shown in Fig. 11, the sealing effect of the cylindrical surface of the plug portion 46 is increased by flexible annular ribs 47 acting like piston rings; an annular flange 48 surrounds the upper end of bore 49 for a similar purpose. The plug may be of plastic, a bush 50 of cork or rubber being fitted on a fluted portion 51 and held between a shoulder 52 and a flange 53 in liquid-tight engagement with a surface 54. According to the provisional specification, relative movement of cap and plug may be limited by means of a spring detent and co-operating recess, or by rigid stops.

Title: Improvements relating to processes for the introduction of alloying constituents in metal melts
IPC: C22C1/02
Filed: 1957-05-06
Abstract: An alloying constituent which melts at a high temperature, such as manganese, copper, nickel or chromium, is introduced into a metal melt in the form of a briquette which contains the alloying constituent as a powder and a salt as refining substance which, after introduction of the briquette, gives off a gas or vapour in amount sufficient to cause spontaneous disruption of the briquette and dispersion of the alloying constituent throughout the melt, the refining substance serving to purify the melt.  The salt is preferably one which evolves chlorine, and may wholly or partly consist of a chloride of an alloying constituent such as manganese chloride which is used with powdered manganese or nickel.  Lead chloride may be used with powdered nickel.  Other salts of the same acid as the refining salt may also be present, e.g. sodium chloride and/or potassium chloride.  The briquette may also contain substances capable of dissolving a deoxidation product, e.g. a fluoride.

Title: Improved cellulose material and a process of preparing it
IPC: D06M13/322
Filed: 1937-05-24
Abstract: Natural or regenerated cellulosic materials are given hydrophobic properties and their behaviour towards dyes is improved, by treating the materials with an a -halogen ether of the formula R-O-CHR1-x (where x is halogen, R and R1 are alkyl, aryl, aralkyl or cyclo-alkyl, and R1 may alternatively be hydrogen) in the presence of a tertiary amine, or with an addition product from a tertiary amine and such a -halogen ether, in an indifferent solvent, an aqueous solution or suspension, and simultaneously or subsequently treating the cellulose with another substance which imparts hydrophobic properties, e.g. paraffin wax, a salt of alumina, or a fatty acid methylolamide of high molecular weight.  The impregnation is carried out at a temperature above 100 DEG  C., or the material is treated, after impregnation, at such temperature.  In a modification, an alkylene oxide is caused to act upon the cellulose, before, during or after impregnation with the a -halogen ether.  In an example, dyed viscose artificial silk is passed through a bath containing di-(octadecoxymethyl) - tetramethylmethylene - diammonium dichloride (from 2 mols. of octadecyl chloromethyl ether and 1 mol. of tetramethylmethylene diamine) and aluminium formate.  The centrifuged fibre is dried at 120-130 DEG  C.  In a second example, the impregnating bath used for the treatment of cotton calico contains octadecoxymethyl - pyridinium chloride and paraffin wax dissolved in tetrachlorethane.  In another example, artificial silk goods are placed in alcoholic caustic soda, squeezed, dried and treated with a solution of ethylene oxide in carbon tetrachloride.  The goods are then treated in a bath containing palmitoxymethyltriethyl ammonium chloride, palm-nut oil fatty acid methylolamide and aluminium acetate.  A number of other suitable quaternary compounds derived from a -halogen ethers are specified. Specifications 426,482, 466,817, and 469,476 are referred to.  The Specification as open to inspection under Sect. 91 refers also to the use of the a -halogen ethers and tertiary amines in the absence of other waterproofing agents, and also to impregnation and drying at temperatures not necessarily above 100 DEG  C.  Examples of these modifications are included.  This subject-matter does not appear in the Specification as accepted.
