Abstract: Alkanes are dehydrogenated by passage through alternating dehydrogenation zones and selective oxidation zone(s), in which latter zone(s) hydrogen produced in the preceding endothermic dehydrogenation reaction is selectively oxidized to generate heat for the succeeding dehydrogenation reaction. New catalyst compositions are prepared comprising reduced and sulfided nickel crystallites on siliceous supports which have been treated with chromium compounds and oxidized to provide surface-anchored chromyl species. Also new catalyst compositions are prepared by sulfiding nickel-containing compositions with carbonaceous sulfur compounds such as dialkylsulfoxides. Another embodiment of the invention is catalyst and dehydrogenation therewith, in which pores having radius of 50 to 200 Angstroms occupy pore volume from 0.30 to 1.50 ml per gram of the support, and pores having radius of 20 to 50 Angstroms occupy pore volume less than 0.1 ml per gram of the support.

Abstract: A method for processing a dehulled, defatted oilseed protein meal, e.g., soybean meal, to produce non-porous, meat-like fibers comprises preparing an oilseed protein source and water mixture, extruding the mixture under predetermined conditions, coating the extruded mixture with an edible oil or fat and then further extruding the oil- or fat-coated fibers under specified conditions. The mixture may further comprise meats, fruits, and/or other vegetables as a source of water. The extrusion conditions and the oil or fat coating act to inhibit the expansion of the extruded, non-spongy fibers. The resulting product has a non-porous texture and resembles broiled meat fibers.

Abstract: Provided is an ergonomic cutting device for cutting casts and other rigid objects comprising an oscillating cutting blade driven by a motor, a handle, and a vacuum system. The present cutting device is designed such that the offset positioning of the motor enables the weight of the motor to help manipulate and make more efficient the device. The vacuum system cools the device and draws dust produced by the cutting blade through the device without contacting the dust with the motor or other mechanical components. The motor is designed to initially engage in an idle mode when the device is turned on, then automatically sense when a load is placed on the cutting blade and, at that point, boost to a cutting mode. The motor may also be manually placed in a higher powered turbo mode. The device also includes a dynamic braking system which enables the device to stop oscillation of the blade faster than previous device.
