IPC: B65G19/16
Filed: 1935-08-02
Abstract: 462,387. Endless-chain conveyers. REDLER, A. Aug. 2, 1935, No. 21984. [Class 78 (i)] Flights sweeping the full width of the floor of the trough of an en masse conveyer have their articulated interconnections positioned above the maximum level of the material being conveyed. As shown, links 15 interconnecting the flights are jointed together in the manner described in Specification 421,986, the flight elements 18 depending downwardly from the joints (Figs. 1, 2, and 4), or intermediately of the links (Fig. 7) ; in the latter case their limbs 18A, 19B, and 20A are successively backwardly directed with respect to their direction of movement to prevent distortion of the chain under the load. The chain passes round a driving sprocket in the form of a double disc element 8, and a similar tensioning sprocket 8<1> journalled in a spring-actuated sliding plate 12. In the construction of Figs. 1 and 2, the flight elements are inwardly directed, the chain being located against the outer walls of the trough 1 which is divided into two runs bv a partition 5. In Fig. 4 the flights are outwardly directed, and the inner walls 5A, 5B of the two runs of the trough are consequently spaced. The material is introduced through one or more hoppers 24, and discharged by way of one or more shoots 25. The flights may be of inverted T-form, instead of U-form as shown. Specification 460,894 also is referred to.

Patent GB-376973-A (GB)
Title: Improvements in and relating to the manufacture of threads or strips of rubber or the like
Filed: 1931-08-04
Abstract: Threads and strips of uniform rectangular cross section are obtained by cutting a sheet of rubber which has been obtained from latex or other dispersion by processes such as those of Specifications 284,608, 292,964, [both in Class 70, Indiarubber &c.], 347,691, 351,012 and which contains a large proportion of water, say 20 to 60 per cent.  The dispersion may be compounded, concentrated, &c., may include synthetic or reclaimed rubber, and may be pre-vulcanized. The sheet until it is cut may be kept in water.  The sheet is drawn over a plastic-coated drum and cut by circular knives rotating at a peripheral velocity of 30-100 feet per minute.  The knives are lubricated with a solution of glucose, sugar, dextrine, &c. with the result that the threads adhere sufficiently to be handled as if they still formed a sheet, but not so as to prevent their separation at any desired later stage. The cut sheet is taken off by a small roller and wound on a cylinder on which it may be vulcanized.

Abstract: Pigment compositions which give colourings on synthetic materials which are fast to wet rubbing, comprise metal lakes of azo dyestuffs containing sulphonic acid groups with 5 to 15% (by weight of the metal lake) of such water-soluble nitrogen compounds of the aliphatic or cyclic series (i.e. polyamines or condensation derivatives or quaternization products thereof) as have a precipitating action on the aqueous solutions of the dyestuffs. The compositions are prepared by thoroughly mixing the metal lakes with the water-soluble nitrogen compounds, preferably under dry conditions.  Specified water-soluble nitrogen compounds include ethylenediamine, triethylene tetramine, diamino - dicyclohexyl - methanes, dianisidines, diaminodiphenyl ureas, naphthalene diamines and melamine; and preferably condensation products of polyamines or, in a modification of the process, of aldehydes, with compounds containing the grouping <FORM:0837851/IV(c)/1> such as dicyandiamide or guanidine (see Group IV (a)).  In examples, the sodium salts of the dyes 2-chloro-5-amino-1-methylbenzene-4-sulphonic acid or 2-aminonaphthalene-1-sulphonic acid --> 2-naphthol; the calcium lake of aniline-2 : 5-disulphonic acid --> 2-naphthol-3-carboxylic acid-11-naphthylamide; and the barium lakes of aniline-2 : 5-disulphonic acid --> 2 - naphthol - 3 - carboxylic acid - 21 : 41 - dimethoxy - 51 - chloranilide or 2 - naphthol - 3 - carboxylic acid - 21 - methyl - 41 - chloranilide are milled with condensation products from polyethylene polyamines and dicyandiamide, a condensation product from urea, dicyandiamide and formaldehyde, a condensation product from dicyandiamide and paraformaldehyde or a polyquaternary ammonium compound from N : N1: N111-pentamethyldiethylene triamine and b  : b -dichlordiethyl ether.

They are used in improving the fastness of colouring of synthetic materials (e.g. polyvinyl chloride) with metal lakes of azo dyestuffs (see Group IV (c)). In examples: (1) dicyandiamide is heated with the following compounds to give a water-soluble product: a mixture of polyethylene polyamines, triethylene tetramine, diethylene triamine or paraformaldehyde; (2) a mixture of urea, aqueous hydrochloric acid, dicyandiamide and formaldehyde is condensed by heating; (3) as in (2) but with ammonium chloride as an additional component and adding glacial acetic acid at the end of the condensation; (4) 0.6% of a mixture of the calcium lake of the azo dye aniline-2 : 5-disulphonic acid coupled with 2-naphthol-3-carboxylic acid-11-naphthylamide and a condensation product from diethylene triamine and dicyandiamide is incorporated into a plasticized polyvinyl chloride foil.
