Abstract: PROBLEM TO BE SOLVED: To obtain a good injection molding material without executing a preliminary mixing between a hard material phase and metal powders by specifying the viscosity of a binder. SOLUTION: At least one kind of the hard material phase is mixed with the metal powders and the binder to form granulated powders. At this time, the preliminary mixing between the hard material phase and the metal powders is not executed before the hard material is mixed with the binder. The binder has a viscosity of 20 to 200cm /10min. at 195 deg.C and under a load of 2.16kg by the DIN standard. Mixing with the organic binder having such a high viscosity brings a high shearing force into a mixture and, as a result, flocculation of the hard material phase or metallic component particles is dispersed or cannot be generated. Therefore, the components inside the granulated material are uniformly distributed, which is reflected to the characteristic corresponding to a produced molded member. Thus, also the flow characteristic of the granulated material during the injection molding is improved, thus the molding of complicated members is facilitated, thereby shortening the binder removing time, too.

Abstract: Preparation of a granulate by mixing at least one hard material phase (A) with a metal powder (B) and binder (C) and then granulating the mixture - carried out without any pre-mixing of (A) and (B) prior to mixing with (C), which has a viscosity of 20-200 (30-100) cm /10 minutes at 195 degrees C and 2.16 kg load, according to DIN 53735. A process for making moulded articles by injection-moulding one of these granulates is also claimed, in which the granulate is shaped in a mould, binder is removed and then the material is sintered.

Abstract: 1. A process for manufacturing an electrode consisting of an electrically conducting support structure bearing an electromechanically active boron-containing nickel layer deposited thereon by electroless deposition from a bath of a nickel(II) salt and a complexing agent by reduction with sodium boranate, wherein said bath contains a molar ratio of complexing agent : nickel salt of from 80 to 200, a molar ratio of sodium boranate : nickel salt of from 0.7 to 4.0, from 10 to 400 mmol/l of a hydroxide of sodium, potassium or an alkaline earth metal which is more strongly basic than ammonia, and from 10 to 80 mmol/l of nickel salt.

Abstract: For the production of preforms of ceramic and/or metallic fibres, a mixture containing the fibres and a thermoplastic binder is moulded by injection moulding or extrusion. The thermoplastic binder used is polyoxymethylene. After the moulding process, the polyoxymethylene is removed by treatment in a gaseous, acid-containing atmosphere or in a gaseous atmosphere containing boron trifluoride.

Abstract: A gas-generating metal electrode comprises hollow profiled sections arranged parallel to one another in a horizontal plane and interconnected by a current distributor. The faces of the profiled sections facing the counterelectrode are curved, the curvature being greater at the sides than in the centre. At the top, the profiled section is terminated by two side faces emerging tangentially from the curvature. The electrode is suitable as anode for chlorine-alkali electrolysis amalgam cells.

Abstract: To prepare a colored pigment which has a metallic luster and consists of a metallic core whose surface is at least partially covered with an iron oxide, iron pentacarbonyl is oxidized with oxygen in a fluidized bed of the metallic cores at above 100 DEG C. The amount of iron pentacarbonyl vapor introduced into the fluidized bed must not exceed 5% by volume, based on the total gases introduced into the fluidized bed over the same period of time.

Abstract: Waste waters containing dissolved saturated and/or unsaturated ketones or aldehydes and/or unsaturated alcohols are hydrogenated before charging to biological purification plants in order to prevent presence or formation of cpds. which inhibit decomposition activity of microorganisms. E.g. waste water containing inter alia 3-ketobutanol-1, methylvinyl ketone, methylbutenol and HCHO is hydrogenated, using Ni-Cu-Mn catalyst at 240 degrees C and 300 atm. H2. Filtered solution is separated into aqs. phase with carbonyl no. 1, iodine no. 0 and 2.54 wt.% C, which is further diluted in 1:20 ratio and charged to biological purification plant, and (b) organic phase which is burnt.
