Title: Modified polyesters and the method of preparation thereof
IPC: C08G63/82
Filed: 1961-03-27
Abstract: Example 1: 5-hydroxy-iso-phthalic acid was prepared from potassium-3,5-dicarboxy benzene sulphonate and potassium hydroxide, esterified with methanol and the resulting dimethyl-5-hydroxyisophthalate was reacted with a p-toluenesulphonyl chloride to yield 3,5-dicarbomethoxy-p-toluenesulphonate.  Example 16:  Reaction of ethyl-p-hydroxybenzoate with p-toluenesulphonyl chloride yielded p-carboethoxyphenyl-p-toluenesulphonate.ALSO:Polyesters are modified with 0.1 to 20 mol. per cent based on the acid component of the residues of sulphonic acid esters of formula (X-Y)n-Y in which X and Y each represent the same or different organic radicals, at least one of which contains at least one ester-forming functional group and the total number of functional groups is 1 or 2; Z is -OSO2- or -SO2O-, is 1, 2, 3 or 4 and when n = 1 the organic radical attached to O is aromatic, and when n = 2, 3 or 4, X is the same or different organic radical.  Ester-forming functional groups mentioned are hydroxyl, acyloxy, carboxyl, carboxyl esterified with alkyl or aryl, or carbohalide.  Suitable sulphur-containing modifiers are listed, mostly for the cases when n = 1 or 2.  The modifiers may be added at any stage of the conventional polyester-forming reaction, preferably towards the end thereof. Conventional additives may be included, e.g. delustrants such as TiO2, and stabilizers such as phosphorous acid. Conventional catalysts may be employed.  In examples 1 to 10, polyesters were prepared from ethylene glycol, terephthalic acid and (1) 3,5-dicarbomethoxyphenyl-p-toluene sulphonate, (2) 3,5-dicarbomethoxyphenyl benzene sulphonate, (3) p-carboethoxyphenyl-p-toluene sulphonate (4), (5) p-carboxyphenyl-p-acetoxybenzenesulphonate.

Abstract: 101,695. Walker, A. H., (Wood, H. A. W.). Oct. 19, 1915. Stereotype. - T h e valve 131, Fig. 5, controlling the supply of metal by the pump 147 to a mould for casting stereotype plates, is itself controlled by the presence or absence of a complete matrix in the mould. As shown, the pump is driven continuously by means of a cam 140, Fig. 1, on a driving-shaft 40 acting upon a spring-pressed arm 142 to rock a shaft 143 which, through an arm 264 and pin 262<a>, operates an arm 144 connected to the pump plunger 145. The valve 131 is normally held open, so that no metal is supplied to the mould, by means of a latch 129, Figs. 1 and 4, bearing on the end of the valve-rod 130 and carried by a rock-shaft 128 provided with an arm 127 engaging the end of a pin 126 slidably mounted in the upper part 95 of the casting-mould, the lower end of the pin 126 penetrating into the casting space when no matrix, or only a special dummy matrix having a corner cut away, is present in the mould. The lower part 93 of the mould reciprocates vertically, and when a complete matrix is present in the mould and the part 93 is in casting position, the pin 126 is lifted and the latch 129 thereby moved clear of the valve-rod 130, so that on the next upward movement of the pump plunger, the valve 131 closes and metal is.supplied to the mould. The valve may be held depressed when desired, for instance while repairing the machine, by turning the shaft 128 to bring a catch 152 thereon over a collar 153 fast on the valverod 130.

Title: Improvements in or relating to processes of treating an impure solution or liquid containing organic material, particularly processes of purifying sugar solutions and the like
IPC: C13B20/12
Filed: 1942-08-24
Abstract: A process for treating an impure acidic liquid containing organic materials, particularly an acidic sugar or dextrose solution obtained in the acid conversion of starch products in the production of sugar, or in the treatment of aqueous wood extracts, comprises treating the liquid first with an active carbonaceous material, particularly a decolourizing carbon, and then with an acid-adsorbing or acid-removal body.  After treating the liquid, if necessary, with a hydrogen-exchange body, e.g. a zeolite prepared by the treatment of wood, lignite, coal, or other carbonaceous material with strong sulphuric acid, or a cation-exchange body such as a condensation product of a polyhydric phenol and formaldehyde, whereby the inorganic salts are converted into the corresponding acids, it is passed through a bed of granular activated carbon where colouring-matter and other organic colloids and dissolved organic impurities are removed.  The liquid is subsequently passed through the acid-adsorption body, which may consist of a m-phenylene-diamine-formaldehyde, aniline-aldehyde, guanidine-formaldehyde, or dicyandiamide resin or an oxide of iron or aluminium.  The liquid when passed through the carbon bed should have a pH value less than 7 and preferably less than 4.3, and the carbon can then be reactivated when exhausted by treatment with a dilute alkali solution, e.g. a 0.5-5 per cent solution of sodium hydroxide. The solution used may be that which has already been used in regenerating the acid-absorbing material.  Prior to reactivation, the carbon is preferably washed with water, and after treatment with hot or cold alkali, it can be treated with acid, e.g. sulphuric or hydrochloric acid or, preferably, carbon dioxide, to facilitate removal of the alkali by further washing. The alkali solution can be treated for recovery of the contained substances.  In order to prevent inversion of the sugar, a small amount of alkaline substance may be added to restore the pH value to at least 7, any carbon dioxide dissolved in the liquor being preferably first removed by aeration.  Specification 554,826 and U.S.A.  Specification 2,151,883 are referred to.
