Abstract: The present invention relates to a process for making a bread product. The process includes the addition of a non-maltogenic exoamylase that hydrolyses starch to a starch medium, and the application of heat to the starch medium. The non-maltogenic exomylase cleaves one or more linear malto-oligosaccharides, predominantly consisting of from four to eight D-glucopyranosyl units, from non-reducing ends of amylopectin side chains. The non-maltogenic exoamylase has an endoamylase activity of less than 0.5 endoamylase units (EAU) per unit of exoamylase activity.

Abstract: The invention concerns a method of testing an evaluation circuit (10 11), which checks the correct contact of a switch (13) with a testing means (14) in a d.c.-supplied circuit. The testing means (14) includes for example a capacitor (15) in parallel with the switch (13). The evaluation circuit (10) itself is made up of a controller (11), an input and an output buffer (17 18). To determine faulty conditions in the output buffer (17), the invention arranges that when testing for faults both the input and the output buffer (17 18) be actively connected by connecting them connected to the controller (11) via a respective data line (21 21a) for exchanging data.

A random generator is applied to drive the container for rotation about one or more of the axes at a speed and/or in a direction of rotation such that the container tumbles with a constantly irregular mixing movement and with a constantly changing Froude number.

Abstract: A polymer granulate whose particles consist of a core component and a coating component can be prepared by mixing a granular polymer with a pulverulent coating agent. The core component is made of a water-soluble polymer, in particular a polyvinyl alcohol. The coating component is a water-soluble or water-insoluble substance which is applied to the water-moistened particles of the core component. The particles of the polymer granulate have diameters within the range from 0.6 to 6 mm. The granulate has particularly good freeflowing properties; it is especially suitable for preparing adhesives.

Abstract: In order to preserve the solubility of films and moldings of polyvinyl alcohol in cold water even under the action of an aggressive atmosphere, in particular a strongly acidic atmosphere, the thermoplastically processable polyvinyl alcohol composition used for the preparation of the films and moldings is stabilized by the addition of a water-soluble polymer or copolymer which is composed to the extent of at least 70% by weight of monomer units which are carboxylic acid amides at least monosubstituted on the amido nitrogen. N-vinylpyrrolidine, N-vinyl-N-methylacetamide and the alkali metal salts or the ammonium salts of 2-acrylamido-2-methylpropanesulfonic acid have proved to be particularly suitable representatives of this group of compounds.

Abstract: For the thermoplastic processing of polyvinyl alcohol, the processing temperature must be below the decomposition temperature of the polyvinyl alcohol; this is attained by incorporating plasticizers. For preparing a plasticizer-containing granular polyvinyl alcohol wherein the plasticizer is homogeneously distributed, there is used as starting material a granular polyvinyl alcohol consisting substantially of particles having a definite diameter. The plasticizer is incorporated in the presence of a small amount of water insufficient to dissolve the polyvinyl alcohol, and the temperature is adjusted in a definite manner during the mixing operation. Simultaneous presence of fine particles of a high molecular weight organic compound soluble or dispersible in water is advantageous. The plasticizer-containing granular polyvinyl alcohol is suitable for the manufacture of any shaped articles, especially films and sheets.

Abstract: A pulverulent polymer composition which is readily pourable, has a low tendency to form dust and has good stability on storage is composed of a mixture of a vinyl ester polymer and a small proportion of a hydrophobic silica. The composition is prepared by spray drying an aqueous vinyl ester polymer dispersion in the presence of a hydrophobic silica. The silica is preferably a product from the reaction of a hydrophilic silica with an organochlorosilane. The composition can be redispersed in water and the films produced from such dispersions are transparent; they are suitable for the production of paints, glues and adhesives.

Abstract: The water content of a material, which tends to either absorb water or to release water, is changed with the aid of a film, which at least partially separates the material from the adjacent space and is impermeable to liquid water but permeable to gaseous water. Polyvinyl alcohol with a particular degree of polymerization and degree of hydrolysis is used as the film material. The film can be mechanically or chemically after-treated. The moistening or de-moistening of the material, which is solid, liquid or gaseous, is effected, utilizing a water vapor pressure gradient, under very mild conditions.
