Filed: 1955-06-30
Abstract: 787,761. Toggle presses. GOLDING, W. F. July 2, 1956 [June 30, 1955], No. 18989/55. Class 87(2). [Also in Group XXIV] A crank mechanism for a toggle-actuated press comprises four gears 15 secured to a driving shaft 11, each gear 15 meshing a gear 16 having at least one hub 17 supported in a journal-type bearing 18 and a single crank pin in the form of a rod 19 extending through all four gears 16. The arrangement is such that when the mechanism is under load, the crank formed by the rod 19 and gears 16 is not subjected to torque. The shaft 11 is driven from an electric motor 12 through belt reduction gearing 13, and a worm gear 14. Connecting rods 20 on the crank 19 are mounted on pivot pins 9 joining the upper and lower arms 7, 8 of a toggle 5 between a fixed base 4 and a vertically movable platen 3. A toothed sector 21 on the toggle arm 8 meshes a correspondingly toothed sector 22 on the lower arm of another toggle 6, thereby constrained to move simultaneously with the toggle 5. Reciprocation of the connecting rod 20 thus raises and lowers the platen 3 of the press with respect to an upper fixed platen 1.

Patent GB-582427-A (GB)
Title: Crimped fibres, filaments and threads of cellulosic nature and a process for their preparation
IPC: D02G1/14
Filed: 1943-11-26
Abstract: Crimped fibres, filaments, or threads of cellulose or regenerated cellulose in which the crimp is resistant to boiling alkaline soap solutions are obtained by mechanically crimping in such manner that the crimping curve has points of inflection, i.e. points where the direction of curvature changes from one sense to the opposite sense and where the curvature passes through zero value, and that the ratio of the length of the crimped material to that of the stretched material is less than two thirds, and the crimped materials are then treated with hardening agents to set the crimp.  The crimp may be imparted by associating the fibres by weaving, knitting or similar process so as to form a yarn, fabric or like product, treating the associated fibres with a hardening agent and then resolving the hardened product into the constituent fibres.  A system of intermeshing rods may also be used for imparting the crimp.  The hardening agent may be formaldehyde, an alkylol-urea, a water-soluble condensation product such as a phenoplast, or aminoplast, if desired together with a catalyst. After the material has been impregnated with the hardening agent it is subjected to a heating operation to effect the required hardening.  The crimped material can be transformed into yarns or fabrics possessing a wool-like, soft touch. In an example, a rep weave fabric with regenerated cellulose warp and cotton weft is treated with a solution of dimethylol urea with ammonium sulphate as catalyst.  The impregnated fabric is dried and then heated to 125-150 DEG  C. to insolubilize the resin.  The fabric is unravelled and strongly crimped rayon fibres are obtained from the warp. Knitted regenerated cellulose fabric is impregnated with a solution of dimethylol urea and sodium phosphate.  After impregnation and hydro-extraction, the fabric is dried and then heated to 130 DEG C.  The material is resolved into filaments which are then cut into fibres.  Other hardening agents which may be used are solutions of formaldehyde and urea or hydroxyethyl urea. In another example, a rayon fibre or yarn is impregnated with a soluble urea-formaldehyde pre-condensation product and sodium phosphate as catalyst.  It is then gripped between two intermeshing rows of small rods so that the depth of crimping is 1/16 of an inch.  During this process the fibre or yarn is heated to about 150 DEG  C.

Filed: 1925-08-07
Abstract: 246,394. Imray, 0. Y., (Soc. of Chemical Industry in Basle). Aug. 7, 1925. Azo dyes are produced from 3-aminonaphthalene-1:8-dicarboxylic acid either by coupling it with a diazo compound or by diazotizing it and coupling with a component. The products are of a mordant character, and by selection of the diazo compound or component, acid, direct-dyeing, or lake dyestuffs may be obtained. By treating with agents yielding chromium, the dyestuffs yield chromium compounds which dye wool in various shades and can be used in chrome printing on cotton. According to examples dyestuffs are obtained by diazotizing sulphanilic acid or 5-nitro-2-aminophenol-4-sulphonic acid and coupling the diazo compound with the anhydride of 3-aminonaphthalene-1: 8-dicarboxylic acid; the diazo compounds of a toluidine-sulphonic acid, a chloraniline-sulphonic acid, an aminophenolether-sulphonic acid, a naphthylamine.sulphonic acid, p-nitraniline-o-sulphonic acid, the various chloro-, nitro-, and methylaminophenol-sulphonic acids, or the carboxylic acids of o-aminophenols may also be used. In other examples, the dicarboxylic anhydride is diazotized and coupled with salicylic acid or 1 : 8- aminonaphthol-4 : 6-disulphonic acid. The following bodies are also mentioned as coupling components : cresotinic acid, acetoacetic esters and arylides, methylketol, 1-arylpyrazolones, #-naphthol, ethyl-#-naphthylamine, the naphthol and dioxynaphthalene sulphonic acids, 1 : 8-aminonaphthols and their N-acidyl derivatives, and the 2 : 8 : 6 and 2 : 5 : 7 aminonaphthol sulphonic acids. In other examples, the dyestuff from diazotized 6-nitro-2-amino-phenol-4-sulphonic acid is converted into a chromium compound by boiling with chromium formate, and those from diazotized. 4-nitro-2-aminophenol-6-sulphonic acid, and 2-aminophenol-4-sulpho-6-carboxylic acid by boiling with chromium fluoride. In further examples the dyestuffs obtained by diazotizing the 3-aminonaphthalene-1 : 8-dicarboxylic acid and coupling it with. 1-amino-5-oxynapthalene-7-sulphonic acid. 2-oxynapthalene-6-sulphonic acid or 1-oxynapthalene-4-sulphonic acid are converted into chromium compounds by boiling with chromium acetate.
