Patent EP-0323270-A1 (EP)
Inventor: BELL WELDON K
IPC: C07C43/04
Filed: 1988-12-30
Abstract: A process is disclosed for converting light olefin(s) to alcohol(s), ether(s) or a mixture of alcohol(s) and ether(s) which comprises contacting a feed containing at least one light olefin with water in the vapour and/or liquid phase under olefin hydration conditions in the presence of a large pore zeolite as catalyst to produce said alcohol(s), ether(s) or mixture thereof. The process is especially applicable to the hydration of a propylene-containing feed, for example, a refinery FCC stream containing a substantial amount of propylene, to provide a mixture of isopropyl alcohol (IPA) and diisopropyl ether (DIPE) which is particularly useful as an octane improver for gasoline.

Abstract: According to the invention an arrangement is proposed for training and practicing ball games, in particular golf. The arrangement can be used indoors as well as outdoors and comprises, on the one hand, a scoring means, preferably a panel (20) with a specifically prepared surface (28) and, on the other hand, a number of "golf balls" (10) having a surface likewise specifically prepared. The said surface preparation is such that the panel immediately catches and retains a ball when hit by it, so that the hitting point on the panel can be observed and taken down. However, the balls do not cling to each other or to carpets, curtains etc. occurring indoors. The surface of the panel (20) is prepared with so called Velcro material (25). By means of the arrangement a game of golf can be practiced while imitating the play on a real golf course and while using the so called score card of this course. For training so called "putt" strokes the panel (20) can be replaced by a small cylindrical body or a thin circular plate of the same diameter. To catch the ball upon a hit the periphery of the body and the top side of the plate are prepared in the same way as the surface of the score panel (20) mentioned above.

Abstract: Batches of hydroxide sludges are successively converted with various reagents in a reaction container, thus transforming by oxidation the chrome hydroxide into chromate. The zinc hydroxide is extracted by alkalis. The chrome hydroxide in the residue of the alkali processing is oxidized into chromate. Copper and nickel are extracted with acids from the oxidation residues. The remaining residual sludge contains essentially iron hydroxide. Copper oxide is precipitated from the solution, separated from the nickel solution and finally dissolved in acid. The separation can be carried out in a single container and supplies the separated components of the hydroxide sludge in a form that allows these components to be recuperated as useful materials.

Abstract: Tuyère à jet d'eau destinée à être utilisée dans des métiers à grande vitesse. Dans une tuyère à jet d'eau ordinaire pour métiers, un organe d'alimentation en fil de trame se compose au mieux d'acier durci, et un stabilisateur redresseur de courant de jet d'eau se compose d'une résine dans la plupart des cas. Lorsqu'on utilise ce type de tuyères ordinaires dans un métier à grande vitesse, la résistance à la corrosion de ces parties se révèle être insuffisante, et leur durée de vie est assez courte. L'objet de la présente invention est la production d'une tuyère à jet d'eau pour métiers, présentant une grande résistance à l'usure et à la corrosion, ainsi qu'une excellente stabilité à grande vitesse. A cet effet, on prévoit une tuyère dans laquelle est incorporé un organe composé d'un orifice et d'un stabilisateur réalisés intégralement en un matériau de grande dureté et de grande résistance à la corrosion, une aiguille réalisée en un matériau de grande dureté et de grande résistance à la corrosion étant également incorporée dans ladite tuyère. La présente invention est particulièrement adaptée à des métiers à très grande vitesse.

Abstract: In electrical switch devices having two contactors, there is a problem that the fixed contact elements of the two contactors must be connected to one another. Particularly when using the contactors for high currents, connection by means of current leads is unfavourable. The electrically conductive connections are therefore constructed in each case as one piece with the two associated fixed contact elements (20, 22; 21, 23), as busbars (26, 27) having a U-shaped cross-section at least on the region of the contact elements. The fixed contact elements are arranged on the lower U-limbs, while the upper U-limb represents the electrically conductive connection of the contact elements which are connected to one another in pairs. The housing can be divided in a plane parallel to the longitudinal extent of the busbars, so that the busbars (26, 27) can be pushed into the housing (28) from the dividing plane. <IMAGE>
