Title: Improvements in connectors for liquid containers
Inventor: BAILEY VICTOR SAMUEL
IPC: F16L37/18
Filed: 1968-04-09
Abstract: 1,215,985. Pipe connections. GRUNDY (TEDDINGTON) Ltd. 9 April, 1969 [9 April, 1968], No. 16997/68. Heading F2G. Two diametrically opposed cams 13, operated by levers 14 and mounted on a housing 10, which fits over the outlet of a gas pressurized liquid container, act on a flanged unit 11 which sealably carries a dispensing outlet tube 15, causing the outlet tube to press down the container seal and communicate with the container extractor tube to permit outflow of liquid. A seal 16, with a flanged metal plate 17 providing stiffness at its lower end, provides the sealing for the outlet tube 15 in the flanged unit 11 and for the container outlet during liquid outflow to prevent spillage. Gas may be supplied under pressure through the top-fitting to the container to pump out the liquid by means of an inlet 18 and holes 20 in the seal 16, which deforms during the depression of the outlet tube 15 causing part of the seal, around the holes 20, to move away from the flanged unit 11. Thus gas can only pass the seal 16 when the outlet tube 15 is depressed. Alternatively, the seal may be in the form of a ring (23), Fig. 2 (not shown), with a lip (23a) contacting the outer diameter of the outlet tube 15 at its lower end 15a, allowing gas to pass the seal only into the container. Here the outlet tube 15 and gas inlet tube 18 are sealed in the flanged unit 11 by lock-nuts (22) and sealing rings (21), and the outlet tube is inclined. Substantially all of the parts of the top fitting can be made of plastics.

Title: Improvements in and relating to the production of cellulose methyl ethers
Inventor: HITCHIN ERIC WILFRED
IPC: C08B11/02
Filed: 1960-05-16
Abstract: <PICT:0909039/IV(a)/1> Cellulose is treated with aqueous caustic soda of 40-55% w/w concentration at temperatures within the range 35 DEG -56 DEG C., the actual conditions used lying within the area marked on the graph. The alkali cellulose so produced is methylated by treatment with methyl chloride containing an inert diluent in which methyl chloride is soluble, such as an ether.  Particularly good results are obtained when the methyl chloride contains 45-90% of its weight of dimethyl ether.  Methylation, under these conditions, is uniform and the cellulose ether so produced has similar viscosities in water and in organic solvents.  In the examples, dry cellulose sheet is methylated to a methoxyl content of 26,3-31,7%. Hydroxyethyl and hydroxypropyl methyl ethers may be produced by additionally reacting the alkali cellulose with ethylene or propylene oxide.

Title: Process for the manufacture of copper phthalocyanines
IPC: C09B47/067
Filed: 1935-06-20
Abstract: Copper phthalocyanine is prepared by reacting phthalonitrile with cuprous halide and a tertiary organic base such as pyridine or quinoline, the molecular proportion of the cuprous halide to the tertiary organic base being above the ratio of 1 : 10 and/or the reaction being effected under pressure at a temperature above about 120 DEG  C.  Alternatively, phthalonitrile, cuprous halide and a tertiary organic base, such as pyridine or quinoline, are reacted together, the reaction being commenced with a relatively larger amount of the base and the concentration being constantly increased in the course of the reaction by distilling off the base.  Preferred temperatures lie between 120--180 DEG  C. and the preferred time of reaction is longer than 2--3 hours.  In examples: (1) phthalonitrile, pyridine and cuprous chloride are heated at 145 DEG  C. for 3 hours in a stirring autoclave giving a 51 per cent yield; working at 180 DEG  C. a 91 per cent yield is obtained; (2) phthalonitrile, pyridine and cuprous bromide are heated at 125 DEG  C. for 2 hours in a stirring autoclave to give a 56 per cent yield; continuing the reaction for 10 hours gives a yield of 87 per cent; (3) the influence of the molecular ratio cuprous bromide: pyridine is shown by the results obtained by heating phthalonitrile, cuprous bromide and pyridine at 120 DEG  C. in an iron autoclave using an increasingly higher molecular ratio of the two latter reactants; (4) phthalonitrile, i.e. pyridine and cuprous chloride are heated under reflux for 3 hours, the pyridine is then distilled off under reduced pressure and the temperature thereby finally raised to 170 DEG  C., reduced pressure being an advantage towards the end of the distillation; a yield of 90 per cent is obtained.  The Provisional Specification specifies as the working conditions applied alone or in conjunction (a) a reaction temperature above about 120 DEG  C., (b) a reaction time of more than one hour, (c) a molecular ratio of cuprous halide to tertiary base above 1 : 13,5.
