Abstract: The invention relates to a method for purification of metallurgical grade silicon where a calcium containing compound is added to molten silicon prior to or after the silicon is tapped from the furnace. The silicon is cast and solidified at a relatively high cooling rate and the solidified silicon is crushed and subjected to a purification process consisting of two leaching steps. In the first leaching step the silicon is treated with an aqueous solution of FeCl3 or FeCl3 and HCl which causes disintegration of the silicon, and in the second leaching step the silicon is treated with an aqueous solution of HF or HF/HNO3. Calcium-containing compound is added to the molten silicon in an amount necessary to provide between 0.3 and 0.95% by weight of calcium in the molten silicon and the weight ratio between Al and Fe in the molten silicon is regulated to between 0.5 and 2.0 by addition of aluminum to the molten silicon.
Abstract: A connecting rod of a crank mechanism is made as a single sheet metal part by shaping without chip removal out of sheet metal. The connecting rod comprises a base sheet (1) that is provided with an upper connecting rod eye (2) and a lower connecting rod eye (3). Each of the connecting rod_eyes (2, 3) has an integral cylindrical stamping (6, 7). The connecting rod further comprises a stiffening collar (8) that is integrally formed out of the base sheet (1) and is configured without interruption on the periphery of the base sheet (1).

Abstract: The present invention relates to a process for producing aliphatic C3-C10-alcohols, in particular 2-ethylhexanol, from high boilers by thermal treatment in the presence of an alkali metal compound and subsequent hydrogenation of the volatile products.
Abstract: The transfer device is a circular conveyor having a plurality of radially moveable grippers. The grippers receive a non-self-supporting package, such as a newspaper jacket, on its bottom edge from an overhead line conveyor and rotate the newspaper down onto a receiving device such as a bundler at the bottom of the drum's rotation. The transfer device controls the gripping of the newspaper from the line conveyor with an inhibitor cam to provide a controlled bypass mechanism. The radial moveable grippers allow for smoother transistion and decrease space needs.
Abstract: The hose reel suitably has a hub mounted on a frame to accept an air hose, said hub being rotatable to wind the air hose. Wheels are attached to one end of the frame and at least one leg is affixed to the back of the frame. The leg enables the frame to be stable when it is rotated 90° off the wheels and onto the leg.
Abstract: A process for the production of vinyl acetate comprising contacting in a first reaction zone a gaseous feedstock comprising essentially ethane with a molecular oxygen-containing gas in the presence of a catalyst to produce a first product stream comprising acetic acid; contacting in a second reaction zone a gaseous feedstock comprising essentially ethane with a molecular oxygen-containing gas in the product stream comprising ethylene; contacting in a third reaction one the first gaseous product stream and the second gaseous product stream with a molecular oxygen-containing gas in the presence of a catalyst to produce a fourth product stream comprising vinyl acetate; separating the product stream from step (3) and recovering vinyl acetate from said product stream from step (3).

Abstract: The present invention relates to novel expression vectors which can produce foreign proteins as soluble forms by using lysyl-tRNA synthetase and a process for preparing foreign proteins by using the expression vectors. Particularly, the present invention relates to the expression vectors which can provide foreign proteins as fused and soluble forms by exploiting the structure and expression pattern of lysyl-tRNA synthetase and the processes for preparing foreign proteins in E. coli effectively, which can be utilized industrially to produce active proteins in mass.
Abstract: By adding an evacuated vertical structure onto a body of water where part of the structure extends above the body of water, the water level rises into the structure because of the vacuum. Use of the structure increases the overall volume of water in an aquarium and provides added space for fish as well as enhanced viewing of the aquarium.
Abstract: The invention relates to a supported catalyst and the production and use thereof in the synthesis of vinyl acetate in the gaseous phase from ethylene, acetic acid and oxygen, or from gases containing oxygen, whereby the activity and selectivity are simultaneously improved. The catalyst contains palladium, at least one alkali metal compound and optionally one or more catalyst accelerators, in particular, gold, barium and/or cadmium on a porous support. Said support contains at least one reducible metal oxide, in particular oxides of the elements of groups IIIb, IVb, Vb, VIb from the periodic table of elements. Once the support has been loaded with at least one palladium compound, a reduction is carried out at a temperature of >200° C.

Abstract: The scent delivery system employs a single conduit with a nasal interface at one end and a fan or canister of compressed air at the other end. In between the two ends a scent injection device is positioned. The injection device injects scent into an air flow created by the fan or canister and creates scented air which is carried to the nose by the flow of air.
Abstract: The invention proposes a variable valve train (1) for throttle-free load control of an internal combustion engine. Each cylinder of the internal combustion engine is provided with two inlet valves (9). According to the invention, each inlet valve (9) cooperates with a particular adjusting element (8, 8a), and the adjusting elements (8, 8a) can be actuated independently of each another. This additionally enhances the variability of the valve train.
