Title: Process for the production of condensation products with tanning properties
IPC: C14C3/20
Filed: 1953-05-26
Abstract: Tanning agents are produced by condensing a mono- or di-sulphonic acid of a hydrocarbon containing at least two condensed aromatic nuclei or a mixture of such acids, an o-chlorophenol and an aliphatic aldehyde, the o-chlorophenol and aldehyde being simultaneously but separately introduced into the sulphonic acid while condensing the resultant mixture.  The chlorophenol should have at least one free o or p position.  Up to two mols. each of chlorophenol and aldehyde can be condensed per mol. of sulphonic acid.  In examples (1) naphthalene is sulphonated with sulphuric acid and to the product o-chlorophenol and formaldehyde are added separately over an hour the mixture being condensed for a further hour.  The final product is neutralized with ammonia and adjusted to pH 3.2 to 3.5 with acetic and formic acids. (2) Similar to (1), a small amount of formaldehyde being added after the addition of the chlorophenol. (3) As in (1) using 6-chloro-m-cresol instead of o-chlorophenol. (4) Phenanthrene is sulphonated and the sulphonic acid reacted with o-chlorophenol and formaldehyde as in example (1).  (5) Anthracene is sulphonated and the products reacted with o-chlorophenol and formaldehyde as in example (1).  (6) Naphthalene is sulphonated and the product reacted as in example (1) with formaldehyde and a chlorination mixture of phenol containing both o- and p-chlorophenols.  The resulting solutions may be evaporated after neutralizing to give solid products to which may be added solid acid reacting substances such as sodium bi-sulphate, oxalic acid and citric acid, to give pulverulent tannins.  All the products on neutralizing and adjustment of pH dissolve in water and have good tanning action and dissolve the sludge and phlobaphene of organic tanning solutions. Specification 430,343 is referred to.

Abstract: 386,521. Supply meters. JOENS & CO., GES., W. H., 33, Franklinstrasse, Dusseldorf, Germany. May. 25, 1932, No. 14783. Convention date, May 26, 1931. [Class 37.] For the electrical integration of quantities measured by mechanical instruments such as steam and water meters, a slider is moved over a resistance F, Fig. 1, by the water meter &c., thereby varying the ratio of the parts r1, r2 into which it is divided. An induction motor meter has its current winding divided into two parts S1, S2 by a tapping, so that the circuit comprising the winding S1, resistance r1, and an auxiliary resistance W1 is in parallel with the circuit comprising the winding S2, resistance r2 and auxiliary resistance W2. The circuit is completed through a resistance W, the winding S4 of a braking magnet B, and the secondary winding of a transformer T. The pressure winding S3 of the meter is connected across the resistance W. The windings S1, S2 oppose one another magnetically and are so proportioned that they neutralize one another when the slider on the resistance F is at the position corresponding to the zero of the quantity to be integrated. The coils S1, S2 may constitute the primary winding of a transformer, the secondary winding of which is connected to the current winding on the meter. A number of separate quantities may be summed and integrated by providing a resistance F corresponding to each quantity as shown in Fig. 3 each resistance being connected to a separate pair of coils S1, 52. These circuits, each consisting of two branches in parallel, are connected in series between the supply mains. The current through the meter may be maintained constant by means of an iron filament lamp.

Title: Therapeutic glucosides and method of obtaining them
IPC: A61K31/70
Filed: 1962-04-17
Abstract: Anthocyanidin glycosides are isolated from a mixture of anthocyanidin glycosides and sugars by fermenting the sugar content of the mixture by means of yeast which will ferment the sugars but which will not attack the glucosides and separating the anthocyanidin glucosides from the fermented mixture.  The mixture to be fermented may be the juice or an extract of plants or fruit such as the juice or an extract from bilberries.  It is preferable to lyophilize and acclimatize the yeast to the anthocyanidin glycoside content of the mixture before fermentation.  A suitable yeast is Saccharomyces oviformis.  The fermentation may be carried out under partial aerobic conditions and carbon dioxide formed during the fermentation is preferably removed from the vicinity of the fermenting mixture.ALSO:Therapeutic compositions useful for improving visual acuity and for the treatment of vascular diseases which increase the fragility and the permeability of capillary walls contain as the active ingredient anthocyanidin glucosides and an inert diluent or carrier.  The composition may be administered in the form of tablets, drops or injectable solution.

Abstract: The invention comprises complex cobalt compounds of monoazo dyes of formula (I) [HO-R1-N=N-R2]-An wherein R1 is a benzene radical, R2 is a naphtholic or enolic azo compound having an hydroxyl group ortho to -N=N-, R1 and R2 are free from nuclear sulphonic acid groups, A is a -CO2-CH2-CH2-OSO3Na or -SO-CH=CH2 group bound aromatically, n is 1 or 2 and OH is ortho to -N=N-.  They are prepared by treating an azo dye of formula I, or a mixture of such dyes, with a cobalt-yielding agent in known manner, preferably so as to obtain complexes containing one atom of cobalt to two dye stuff molecules.

They dye nitrogenous materials, particularly wool and polyamides in yellow, red and brown shades.  In an example, 2-aminophenol-4-(b -hydroxyethyl-sulphone) is treated with sulphuric acid, neutralized with sodium hydroxide, then diazotized and coupled with 1-acetoacetylamino-2-chlorobenzene and the monoazo dye obtained is treated with aqueous cobalt sulphate solution.  Further cobalt complexes are similarly prepared and in some cases treated with alkalis.  Additional components specified are 2 - amino - 6 - nitro - or -bromo - phenol - 4 - (b  - hydroxethyl - sulphone), 2 - aminophenol - 4 - vinylsulphone and 2 - aminophenol - 4 : 6 - dichlorobenzene; 2 - naphthol, 1 - phenyl - or -(31 - chlorophenyl) - 3 - methyl-5 - pyrazolone, 1 - acetoacetylamino - 4 - chlorobenzene, acetoacetylamino - benzene and 1 - (41 - b  - hydroxyethyl - sulphonylphenyl) - 3 - methyl - 5 - pyrazolone.
