Patent EP-0439701-A1 (EP)
Inventor: JUNG FELIX
IPC: B07B9/00
Filed: 1990-11-09
Abstract: With this method and the device for carrying it out, the sorting of inhomogeneous building rubble is to be improved so that a highly selective separation of the rubble fractions is made possible. For this purpose, building rubble supplied in rubble containers (2) is tipped onto a vibro channel (3) and under the influence of the vibrations produced by the vibro channel (3) is loosened and conveyed to a preseparator (4) with conical screening strips which separate bulky refuse components from the rest of the building rubble. A conveyor belt (13) conveys the building rubble not separated out by the preseparator (4) to the input of a finger screen (12). Between the preseparator (4) and finger screen (12) a magnetic separator (15) is arranged. The finger screen (12) provided with a finger cover (12.4) separates from the rest of the building rubble a fine fraction (C) which for economic reasons is not divided up any further and is taken to tips. The building rubble conveyed to the input of the air separator (14) is divided up in a preseparator section (16) into two fractions which are each conveyed via air streams with the purpose of separating off a light fraction (E) with combustible components from a heavy fraction (D). <IMAGE>

Switching means serves for periodically switching a direction in which the culture medium is circulated between the culture tank and the medium recirculating tank by means of supply and recovery lines. 
     At a bottom or head of the culture tank a separator is adapted to trap any bubble possibly existing in the culture medium or to trap any quantity of cell matrix possibly running out from the culture tank. 
     There may be provided within the culture tank a packed bed filled with the cell matrix. 
     The circulation switching means may comprise a rotary blade provided above or below the packed bed and adapted to be rotated in periodically switched direction. 
     There may be provided within the culture tank a cylindrical member surrounding the packed bed and having upper and lower openings so that a larger gap defined between the cylindrical member and the culture tank may be utilized as the medium recirculating tank.

Abstract: The invention relates to a blind riveting member of the type comprising a tubular sleeve (1) and a mandrel (2) passing through said sleeve. The stem portion (5) of the tubular sleeve (1) comprises successively along its length, a first articulation zone (5a), an inclined portion (5b), a second articulation zone (5c) and an end portion (5d). These zones or portions are arranged in such a manner that the sleeve is subjected to a double folding during setting of the rivet which causes the inclined portion to expand and fold back upon itself toward the materials being assembled, forming a continuous rest surface at the periphery of the hole which contains the riveting member. The invention is applied in particular for assembling fragile materials such as composite materials. It permits providing a good vibration resistant holding for these materials without risk of damaging the same.

Abstract: A precipitation polymerization process for producing a macroporous crosslinked copolymeric lattice, capable of adsorbing hydrophilic and lipophilic fluids, in which process there is copolymerized at least one mono­unsaturated monomer and at least one polyunsaturated monomer in the presence of an organic liquid which is a solvent for the monomers but not for the copolymer, initiating the copolymerization of the monomers by means of a free radical generating catalytic compound, precipitating a copolymer in the solvent in the form of a powder and forming a dry powder by removing the solvent from the precipitated copolymeric powder. One monomer is a hydrophilic compound and the other monomer is a lipophilic compound.

Abstract: A method of producing an abrasive body which consists of an abrasive compact sandwiched between layers of cemented carbide. The method includes the steps of providing an unbonded structure comprising a layer (14) of ultra-hard abrasive particles sandwiched between two carbide layers (10), (18). Each carbide layer (10), (18) is a layer of cemented carbide or a layer containing the components necessary to produce cemented carbide. The two carbide layers (10), (18) and the sandwiched layer (14) each contain a binder metal selected from cobalt, nickel, iron and the like. The concentration of binder metal in the sandwiched layer (14) is less than the concentration of the binder metal in one of the carbide layers (10), (18) and is higher than the concentration in the binder metal in the other carbide layer (10), (18). The unbonded structure is subjected to conditions of elevated temperature suitable to produce the abrasive body.

Abstract: A moldable composition comprising a mixture of magnesia, alumina, and silicon carbide powders or agglomerates thereof, the powders having an overall average size of at most 5.0 micrometers, preferably an average size in the range of 0.2 to 2.0 micrometers, optionally a polymeric binder, optionally a fluxing agent, and optionally a plasticizer or lubricant which exhibits little or no controlled dimensional stability upon being fired to a cordierite ceramic material in a novel process. The process involves incorporation of silicon carbide powder into the moldable composition and the reaction of this silicon carbide upon firing to produce silicon dioxide. The cordierite ceramic material is useful where the dimensions of a shaped or molded part must be preserved after firing, as, for example, in the preparation of dental articles or as a mold for casting metals.

Abstract: Un manipulateur micromécanique comprend un substrat (1), des éléments de chauffage et un bras manipulateur (2) dont le fonctionnement se fonde sur le principe de l'effet bilame. Les manipulateurs connus à effet bilame effectuent des mouvements perpendiculaires à la surface du substrat. Il arrive toutefois fréquemment que l'on souhaite disposer d'un manipulateur capable d'effectuer des mouvements dans le sens de la surface du substrat. Dans le manipulateur décrit, la surface du substrat oppose une résistance mécanique à une déviation du bras manipulateur, bombant celui-ci, réduisant sa longueur effective et entraînant ainsi un déplacement dans le sens de la surface du substrat. Ce bras manipulateur est utile pour entraîner des éléments mobiles dans le plan du substrat, tels que joints articulés et disques dentés.

Abstract: An electrode for engraving electric spark machining which is produced by using a mixture of gypsum hemihydrate powder serving as both a principal material and a binder with a conductive metal powder as a filler, transferring, shaping and hardening the mixture into a desired shape to form electrode material and plating the electrode with the conductive metal. Gypsum hemihydrate powder, gypsum dihydrate powder of less than 1 vol % on the basis of the former and the conductive metal powder are kneaded in a vacuum. Water is added to the kneaded matter, which is again kneaded in a vacuum, poured into a mold to which a predetermined shape is transferred, shaped and hardened by hydration to obtain an electrode material. Then the electrode material is dried and plated with the conductive metal so as to reinforce electrical connection with the metal powder. Since the electrode is made of gypsum as the principal material, even an electrode for electric spark machining to which a precise and complicated shape is transferred can be produced easily, economically, and precisely by the use of a simple mold of, e.g. a silicone rubber, and hence it is particularly suitable for producing dental crowns one by one. Furthermore, gypsum hemihydrate as the principal body of the electrode material and the conductive metal film increase the strength of the electrode by virtue of their synergistic effect. The present invention makes possible machining of a hard material such as titanium for which precise electric spark machining at a desired speed has been difficult by the use of a conventional electrode subjected to impregnation treatment of a conductive solution in which graphite or the like is dispersed in place of plating treatment.
