Title: Improvements in or relating to cellulosic sponge material
IPC: C08J9/00
Filed: 1961-08-09
Abstract: A cellulosic sponge material is treated with a reagent capable of reacting with the hydroxyl groups of the cellulose to provide groups attached to the cellulosic structure, which groups have inherently ion-exchange properties. An oxyacid of phosphorus, e.g. orthophosphoric acid, may be used to provide a phosphorylated cellulosic sponge material, the reaction conditions preferably being such as to provide a product having an ion-exchange capacity of 0,5-10 meq./g. Phosphorylation may be effected by saturating cellulose with a mixture of urea and orthophosphoric acid, squeezing out most of the reagent, curing the treated cellulose in an oven at 130 DEG C. for 2-3 hours, and then washing out unreacted reagent. Other reagents which may be used include citric acid yielding citrate groups attached to the cellulose, and mixtures of strong alkali with either (a) sodium chloroacetate, to yield carboxymethyl groups, (b) aminoethylsulphuric acid, to yield aminoethyl groups, (c) 2-chlorotriethylamine hydrochloride, to yield diethylaminoethyl groups, or (d) a mixture of epichlorhydrin and triethanolamine, to yield basic groups containing tertiary nitrogen. The cellulosic sponge material may be in block or sheet form and may contain scrim or fibrous reinforcing material. It may be prepared by rolling out a crystal paste of viscose and regenerating the viscose by conventional means. Materials so made have a high ion-exchange capacity and good structural rigidity, and liquids flow through such materials rapidly.ALSO:A cellulosic sponge material is treated with a reagent capable of reacting with the hydroxyl groups of the cellulose to provide groups attached to the cellulosic structure, which groups have inherently ion-exchange properties.

Title: Agglomerating pulverulent material by contacting with a film of jetted liquid
IPC: A23P10/22
Filed: 1966-12-06
Abstract: Pulverulent products such as foodstuffs and dietetic products e.g. milk powders, chocolate flavoured beverages and soups, are brought into contact with at least one jet of liquid with an initial velocity of at least 8 metres per second and a temperature of at most 30 DEG C., the product is moistened and carried along by the jet so that the particles are agglomerated, and the product is collected and dried in the form of a powder of agglomerated particles. Water, optionally containing to some extent at least substances to be included in the composition of the pulverulent product, or an aqueous solution or dispersion of the pulverulent product is projected under a pressure of at least 10 kg/cm2 and at a temperature of between 5 DEG and 15 DEG C. through one or more nozzles directed horizontally or inclined obliquely upwards and giving a flat jet of liquid in the shape of a fan at its origin. The pulverulent particles are uniformly delivered from a vibrating feed assembly into contact with the jet of liquid in a quantity sufficient for all the liquid to be absorbed by the particles in a few seconds and the agglomerated particles are dried while suspended above a vibrated screen by air at a temperature of not more than 100 DEG C. Damp air is exhausted from the assembly and fine particules are collected for recycling. An Example is directed to the agglomeration of skim milk powder with the aid of jets of a 10% dispersion of skim milk powder in water.

Abstract: A damping unit for controlling vibrations, e.g. in the overarm 9 of a milling machine, comprises at least one viscoelastic absorber element, e.g. 27 or 28 of varying cross-section interposed between a damper mass 23 and a support location 25, 26 on an adjustably positioned support means, relative movement between the support means and absorber element altering the working height h of the absorber element (Fig. 2) to alter its stiffness and thereby the frequency of the damping unit. The support means may, as shown, comprise a shaft 24 with shoulder portions 25, 26 and adjustment of the positions of the shoulders relative to the absorber elements may be by means of a screw 32 or alternatively, cam means (Fig. 19a, not shown), responsive to movements of the overarm, automatically vary the support locations to vary the frequency of the damping unit according to a predetermined relationship. Alternatively (Fig. 20, not shown) electrical sensing means responsive to the natural vibration of the machine may be used to control the damping units accordingly. The absorber elements may be straight and of generally triangular section (Figs. 14-18, not shown), or annular, or segmental surrounding the damper mass (Figs. 12, 13, not shown). The damper masses may be supported by springs so as substantially to relieve the absorber elements of static loading.
