Abstract: A method and an apparatus for controlling an elevator is equipped with a deck-distance drive machine which by reference to positional information adjusts the distances between the individual cars in a common car sling in such a way that each car can stop at the corresponding floor accurately, i.e. without forming a step. Measured values of floor position are stored in memories and periodically updated so as to detect any changes such as, for example, building settlement. Based on this data the necessary deck-distances are calculated which are necessary for all the cars to stop without any of them forming a step. Furthermore, the method and the device can be correspondingly extended for a multi-decker elevator and for any type of control (conventional control, destination call control, etc.).

Abstract: The invention relates to an apparatus for the mechanical removal of deposits on welding electrodes. Welding electrodes have to be cleaned after a certain number of welding operations due to deposits. Therefore an apparatus is provided which is essentially subdivided into two subassemblies, namely a machining head and a holding device in the form of a stand or pedestal, which can be installed universally and in any position. The apparatus is characterized by a simple construction of a pneumatic motor which is an integral part of the apparatus. The pneumatic motor rotor is housed in a rotary manner in the machining head, which also contains the gear and the holder for the abrading tool to clean the welding electrodes.

Abstract: Refractory gold ores are roasted at temperatures from 500.degree. to 650.degree. C. in an oxidizing atmosphere in a fluidized bed, which is supplied with a carbonaceous additional fuel. To effect a substantially complete combustion of the additional fuel to form CO.sub.2 and H.sub.2 O, methanol is added as a carbonaceous fuel.

Abstract: Water-dilutable coating binder combinations which can be deposited cathodically, and based on epoxy resin-amine adducts, acrylate copolymers and crosslinking components are described. The binders are particularly suitable for formulation of water-dilutable primers and one-coat paints when deposited cathodically are described. In 3 to 30% by weight, based on the solids, of a basic epoxy resin-amine adduct (A) which is free from epoxide groups, 70 to 97% by weight of a monomer mixture (B), which consists of esters of (meth)acrylic acid which contain secondary or tertiary amino groups, of monoesters of (meth)acrylic acid with diols, of (meth)acrylic acid alkyl esters and if appropriate of aromatic vinyl monomers, is polymerized. Components (A) and (B) comprise at least 5% by weight, preferably 10 to 20% by weight, of identical aliphatic radicals having 7 to 18 carbon atoms. The baked films based on these products have a high degree of gloss and an excellent UV, washing agent, and corrosion resistance.

Abstract: A series-shed loom with a weaving rotor (1) and laying-in members (2) which lay the warp threads (3) into high points and low points on the weaving rotor (1) to form the sheds, while the weaving rotor combs through the sheds (6) so formed to beat-up against a beater bar (8) of a meanwhile inserted weft yarn (7). Warp threads (3a, 3b) are laid into gaps (11) in the combs, while the low points (5) of one warp thread (3) are formed in gaps (11) which are in line in the direction of rotation (9). The high points (4) for one warp thread (3a, 3b) are formed by fins (12) which are in line in the direction of rotation and which form longitudinal saddles (13a, 13b) extending in the direction of rotation (9) between a beater nose (14) and a holder nose (15).

Abstract: The iron content of the TiO.sub.2 -containing precursor is subjected to a direct reduction to effect a metallization of at least 90%. The reduced product is separated into magnetic and nonmagnetic fractions by magnetic separation. To oxidize the metallic iron, the magnetic fraction is subjected to an oxidation in an acid medium with agitation at a pH value below 2, under a pressure of 12 to 24 bars, and at a temperature from 150.degree. to 210.degree. C. with a supply of an oxygen-containing gas that contains at least 90% oxygen. When the suspension has been pressure-relieved, the hematite which has been formed is separated from the TiO.sub.2 concentrate.

Abstract: The traversing shed loom has a shedding weaving rotor into which weft yarns are picked. The rotor has shedding elements and beating-up combs in which warp placing guides place warn yarns by moving transversely to the direction of rotor rotation. Most of the warp yarns are deflected transversely to the direction of rotation during shedding and the deflection is cancelled only by the shedding elements moving away before the beating-up of the weft so that the warp yarns are realigned. The beating-up combs have at least two warp yarns per occupied space. The position of guides, the geometry and position of the combs, the position of top shed guides and bottom shed guides and the warp yarn placing program are so adapted to one another that the streakiness, i.e., warp streakiness, is controllable.

Abstract: A mechanical disintegration is effected in which substantially only the metal sheath of the small batteries is torn apart. The crushed material is roasted at 500.degree. to 1000.degree. C. in a state of motion in an oxidizing atmosphere and the volatilized mercury is recovered from the exhaust gas. The roasted material is separated by sieving and magnetic separation into an iron-containing scrap fraction, a brass-containing scrap fraction and a collectable fraction, which contains manganese, zinc and silver.

Abstract: Disclosed is a process for burning cattle dung at a temperature of from 500.degree. to 780.degree. C., preferably from 650.degree. to 780.degree. C., in the presence of one or more aluminum-containing substances selected from the class consisting of bauxite, kaolin and aluminum compound-containing ash from furnaces for firing solid fuels. A major part of the alkalies contained in the cattle dung and a substantial part of the chlorine are retained in combined form in the resulting furnace ash.

Abstract: In a method of processing contaminated sodium oxalate which becomes available in a separating stage succeeding the digestion of bauxite in accordance with the Bayer process, chemicals used in the digesting process are recovered in that moist sodium oxalate which has been separated is dried with the hot exhaust gases from a rotary kiln jointly with aluminum hydroxide or aluminum oxide hydrate and/or reactive alumina at a mole ratio of aluminum to sodium of at least 0.8 and the dried product is decomposed in said rotary kiln at a temperature of 780.degree. to 1000.degree. C. to form sodium aluminate. Suitably drying is effected by spray drying in direct contact with the exhaust gases of the rotary kiln and decomposition is effected at a temperature in the range from 850.degree. to 950.degree. C. and with an Al:Na ratio not in excess of 1.2.

Abstract: The device for the storing of filamentary material contains a thread storage and a feed nozzle associated with it, the thread storage having a thread carrier which rotates past the feed nozzle and the feed nozzle being arranged fixed in position and rigid; and the depositing of the thread (S.sub.1, S.sub.2, S.sub.3) on the thread carrier takes place in the form of thread packages (P.sub.1, P.sub.2, P.sub.3) which consist of partially superimposed turns so that the length of the thread package (P.sub.1, P.sub.2, P.sub.3) and thus of the entire storage can be kept small, so that the storage is particularly suitable for looms, especially when using so-called mixers. The thread carrier is preferably covered by a small plate at the point of the formation of the thread packages, and the thread packages are deposited in the space between the thread carrier and the plate.
