Abstract: This invention relates to a process for the preparation of wort starting from mash, comprising the separation of spent grain from the mash to form a clear wort in at least one membrane filtration unit having a pore size of the filter not exceeding 2.0 .mu.m, if desired addition of hops to the wort and boiling of the wort.

Abstract: An indigestible dextrin characterized in that the dextrin is prepared by heat-treating potato starch with addition of hydrochloric acid thereto to obtain a pyrodextrin, hydrolyzing the pyrodextrin with alpha-amylase and glucoamylase and removing at least one-half of glucose formed from the resulting hydrolyzate, and comprises a fraction other than glucose.

Abstract: A partially baked, laminated dough product such as a croissant or a pastry is made by heating the dough product preferably in an impingement oven to a temperature of about 200.degree. F. to about 210.degree. F. and then immediately freezing the partially baked dough product preferably in a co-current liquid nitrogen freezer so as to prevent a collapse of the partially baked dough product.

Abstract: Fat fractions are produced by a process for the fractionation of fats and oils in which the fat or oil is dissolved in a binary azeotropic solvent mixture. The solvent containing the dissolved fat is cooled to a first temperature to crystallize a high melting stearine fraction, and the high melting stearine fraction is removed from the solvent-crystal mixture. If the fractionation process has for its objective the production of a high melting fat and a lower melting fat (oil), the fractionation process is terminated at this point. However, if an intermediate melting solid fraction is the objective, it is desirable in the first crystallization step to remove a smaller portion of high melting stearine fraction and then to cool the remaining solution to a second temperature lower than the first to crystallize an intermediate melting solid fraction. The second crop is crystals is removed from the solvent-crystal mixture by filtration or decantation.

Abstract: Process for producing a film having at least one monomolecular layer of non-amphiphilic molecules.This process comprises the following stages:(a) combining non-amphiphilic molecules A, such as pyridine, with amphiphilic molecules B, such as a zinc porphyrin, in order to form a complex of molecules A and B;(b) forming on the surface of the liquid a monomolecular layer of the thus obtained complex, and(c) transferring the thus formed monomolecular layer to a rigid support.Molecules A and B can form between them a charge transfer complex, e.g. TCNQ-alkyl pyridinium which makes it possible to obtain laminated structures of organic conductors.

Abstract: According to the invention, the composition contains an abrasive material (12.5-37.5 vol.-%), a metallic filler (30-60 vol.-%), a mineral binder (5-30 vol.-%) and the balance is an organic binder.The mineral binder is constituted by at least one substance from a group of salts whose melting temperature corresponds to the temperature range of polymerization of the organic binder.

Abstract: An improvement in the manufacture of diamond compacts is disclosed in which a cylindrical mass of polycrystalline diamond is surrounded by and bonded to an outer mass of metal which provides support for the diamond. The improvement comprises the use of seed diamond to grow the polycrystalline mass under high pressure-high temperature (HP/HT) conditions from non-diamond carbon, utilizing a catalyst metal contained in the outer metal annulus. Preferably, this improved process is carried out using a cup-shaped metal mass having a stable carbide content of at least 10% and a coefficient of thermal expansion slightly higher than diamond. It is also preferred to heat the sample (the outer metal mass and the inner graphite mass) directly by passing an electric current through the outer metal mass in the HP/HT process during which the polycrystalline compact is formed.

Abstract: Disclosed is a process for dyeing or printing a textile substrate employing an aqueous paste comprising dyestuff and a synthetic thickener, which process comprises the step of applying an electrolyte to the substrate prior to or after application of said aqueous paste, said paste being free from added electrolyte.
