Inventor: LUNET FRANCOISE MARIE GERMAINE
IPC: C09B45/00
Filed: 1964-07-01
Abstract: Sulphonated, sulphocarboxylated or polycarboxylated metallisable dyes are pasted with water and an anionic dispersant, the pH of the paste being such that the dye is practically in the undissolved state at room temperature and the dye particles have a size not greater than 5 microns.  The pastes may then be dried, e.g. spray dried, to form a dry powder.  The pastes and powders so obtained may be employed to dye animal or superpolyamide fibres by known after-chroming or simultaneous chroming (monochrome or metachrome) processes even with very hard water using a bath-circulating apparatus.  In the examples the following aniomic dispersants are employed: (1) dinaphthylmethane disulphonate together with sodium diheptyl sulphosuccinate, (3) as in (1) plus sodium sulphoricinoleate, (4) sodium lignin sulphonate and sulphated lauryl alcohol, (5) as in (1) plus diheptyl sulphosuccinate.

Title: Calculator for determining the centre of gravity of a load carrying structure
IPC: G06G1/00
Filed: 1952-10-29
Abstract: 732,460. Calculating-apparatus. FRIESEN, J. R. Oct. 29, 1952 [Oct. 30, 1951], No. 27168/52. Class 106 (1). Apparatus for determining the centre of gravity of a load-carrying structure comprises a load scale 26 carried by a first part which is perpendicular and slidable relative to a base 12 in which is mounted a slide 15 carrying a pivoted arm 18. Indices 33, 20 on the first part and slide 15 co-operate with a distance scale 14 on the base and a line 21 on the arm 18 co-operates with a reference line 32 on the first part. As described, the first part comprises a bar 22 in which is mounted a slide 23 and over which moves a cursor 34. The arm 18 is transparent and rotatable against frictional resistance which is adjustable by the pivot pin 19. In use, the slide 23 is positioned so that the division of the scale 26 on the bar 22 corresponding with the unladen weight of an aircraft is aligned with the division of a scale 30 on the slide 23 corresponding with the load to be carried in a particular part of the aircraft. The total weight may then be read on the scale 26 against a zero line 31 on the slide 23. The bar 22 is positioned along the base 12 in accordance with the load arm (measured from a predetermined datum) of the weight of the aircraft, and the slide 15 is set in accordance with the load arm of the load to be applied. The line 21 on the arm 18 is then set over the intersection of the lines 31, 32 on the slide 23 and remains in this angular position while the bar 22 is moved until the intersection of the line 32 with the line of the cursor 34 (set according to the unladen weight of the aircraft) meets the line 21 of the arm. It is shown that the position of the centre of gravity of the aircraft so loaded is given by the reading of the index 33 on the scale 14. The effects of additional loads are found in, a similar manner. By using the negative portion of the load scale 30, the effect of removing a load may be found. The scales may be provided with verniers.

Patent GB-442607-A (GB)
Title: Improvements in the manufacture and production of organic sulphur compounds
Filed: 1934-09-24
Abstract: Ethane dithio ethers are prepared by the interaction of vinyl thio ethers with aliphatic or aromatic mono- or polyvalent mercaptans. The vinyl thio ethers are prepared by the process of the parent Specification.  The reaction is one of simple addition thus R-S-CH=CH2+R1SH-->R-S-CH2.CH2.S.R1 where R and R1 may be aliphatic, or aromatic radicals.  In addition to monovalent mercaptans, polyvalent mercaptans such as ethylene mercaptan may also be used. In cases where the reactants are liquids it is usually sufficient merely to mix them together when interation takes place with considerable evolution of heat. The reaction may also take place in the presence of solvents such as benzene, toluene, cyclohexane, chlorbenzene and dibutyl ether, or in the gaseous phase, under increased pressure if desired.  In some cases it is necessary to employ heat to cause the reaction to go to completion, or catalysts such as acids, caustic alkalies, alkali metal alcoholates, ammonia or organic bases may be used. Catalysts are not usually necessary.  The products may be purified by crystallization distillation or precipitation.  They are used as dyestuff intermediates, vulcanization accelerators or for pharmaceutical purposes.  In examples: (1) molecular proportions of p-thiocresol vinyl ether and p-thiocresol are reacted to yield ethane dithio-di-p-tolyl ether, and similarly beta thionaphthol vinyl ether and p-thiocresol yield ethane dithio-beta-naphthyl-p-tolyl ether; (2) 2 - chlor - 1 : 4 - xylene - 5 - mercaptan and vinyl ethyl sulphide yield the ethane dithio ether of the formula <FORM:0442607/IV/1> (3) 1-mercaptoanthraquinone and p-thio-cresol vinyl ether yield <FORM:0442607/IV/2> a corresponding reaction takes place when 2-mercaptoanthraquinone is substituted for the 1-mercapto-anthraquinone.  (4) Two mols. of p-thiocresol vinyl ether react with one mol. of ethylene dimercaptan to yield <FORM:0442607/IV/3>ALSO:Ethane dithio ethers for use as vulcanization accelerators are prepared by the interaction of vinyl thio ethers with aliphatic or aromatic mono- or polyvalent mercaptans.
