Patent GB-987965-A (GB)
Title: New vat dyestuffs and processes for their manufacture
IPC: C09B5/28
Filed: 1961-11-29
Abstract: The invention comprises vay dyes which contain a chromophore of formula <FORM:0987965/C4-C5/1> and a sulphoacylamino group attached through its amino nitrogen atom.  The dyes are prepared by (a) treating a vat dye containing the said chromophore and an acylamino group with a sulphonating agent until at least one sulphonic acid group has been introduced or (b) acylating a vat dye containing at least one acylatable amino group and a chromophore of the above formula with an acylating agent which contains in addition to the acylating group a sulphonic acid group or a sulphohalide group which is hydrolysed to a sulphonic acid group under the reaction conditions.  The sulphonation process (a) may be carried out with oleum or sulphuric acid or with chlorosulphonic acid followed by hydrolysis of the sulphonyl chloride obtained.  Specified acylating agents for process (b) are sulphobenzoyl chlorides, benzoic acid sulphochlorides, disulphobenzoyl chlorides, sulphofuran- or sulphothiophene-carboxylic acid halides, sulphocinnamoyle chloride, sulphonaphthoyl chlorides and 2-sulphobenzoic acid anhydride.  The dyes give olive-green shades on cotton by the usual vat-dyeing processes.  Examples describe the preparation of the dyes.

Title: Flavour powders
Inventor: WAYGOOD WILLIAM ARTHUR
IPC: A23L27/00
Filed: 1964-11-30
Abstract: A flavoured or scented powder is prepared by mixing aromatic material, for example sweet orange oil, nutmeg oil, onion or leek oil, and oleoresin capsicum, with a setting agent, for example glycerol monostearate, a polyethylene glycol, or a fat, which may be at least partially hydrogenated, to obtain a uniform liquid mixture, and spraying the mixture, for example by means of a rotatable atomizer, in the form of molten droplets into an inert cooling atmosphere, for example of carbon dioxide, to set the droplets into powder particles.  The dispersibility of the powder in water may be increased by adding sorbitan or polyoxyethylene esters.  An antioxidant, such as BHA, may be added.  The powder may be diluted with for example rusk, rice-flour, sugar, dextrose, or salt. Aromatic material is defined as a scented or flavoured material that is an oleoresin, an essential oil, a synthetic chemical, a whole extract of a flavouring material, or a partially or wholly detergenated citrus oil.  Setting agents are edible materials inert to the aromatic material, solid at room temperature and with a melting point below 100 DEG C., the molten setting agent being completely miscible with the aromatic material.

A valve for controlling flow of coolant to an I.C. engine radiator has a temperature responsive power element of the wax filled cylinder and plunger type. This element is on the opposite side of the valve seat from the closure part of the valve closure member 18 which is carried by the plunger 44. The plunger is biased in the closing direction by a tension spring 36. The cylinder is biased in the opening direction by a compensating compression spring 34 and is movable toward a fixed abutment base 28. The start-to-open temperature is higher than the start-to-travel temperature of the element, and owing to pump pressure acting on the valve the start-to-open temperature is lowered as pump pressure increases. In the event of excessive pump pressure the valve 18 will blow open regardless of the temperature. The spring locating base 24 is fixed by frame legs 22.

Title: Worsted/synthetic stretch fabric and processes for manufacturing same
Inventor: PINSON MARVIN JOSEPH
IPC: D03D15/56
Filed: 1963-12-20
Abstract: A worsted-type stretch fabric has weft of worsted fibres with a twistless multifilament core of textured nylon or polyester.  The yarn may be singles, in which case the core is given such a twist, before combining with the worsted roving, that it is removed during spinning; alternatively, a twistless core may be used, the twist imparted to it during spinning being removed by plying two or more yarns together; the twist is set by steaming before weaving or, in the second case, before plying.  Weaving is effected with the warp reeded out so that the weft can bulk when the fabric is finished in the relaxed condition.  The warp may be ordinary worsted yarn to produce a fabric having weftwise stretch, or may be the same as the warp to produce two-way stretch. Polyester, nylon, or cotton fibres may be blended with the worsted in the warp and/or weft.  Details of preferred ranges of grade of wool, twist, and threads per inch are given.  Finishing.
