Abstract: A process is disclosed for recovering metallic constituents of spent or waste catalysts containing metallic compounds fixed on an aluminous support. The process is particularly applicable for the recovery of metals such as Al, Mo, V, Ni and Co, contained in spent catalyst. The process comprises transforming the metals to be recovered into volatile chlorides by carbochlorination and then separating the chlorides obtained by dry means and fixing them successively in a selective manner. The separation of AlCl.sub.3 is accomplished by passage through granules of anhydrous NaCl, and the separation of MoCl.sub.5 by passage through granules of crystallized KCl. The process is particularly suitable for the treatment of waste catalyst from the catalytic hydrocracking or hydrodesulfurization of oils.

Abstract: In a process for the carbothermal reduction of alumina, carbon and alumina are supplied to a molten reaction bed in a hearth in the floor of a reactor. The reaction bed is supplied with energy by contact with plasma or with plasma effluents. For this purpose the reaction bed itself may form the counter-electrode for a plasma gun orbiting about the vertical axis of the reactor or there may be an intermediate counter-electrode. In either case the hearth is preferably electroconductive to provide a current path from the material in the reaction bed. Some or all of the feed material entering the reaction bed may enter the upper end of the reactor and descend through the plasma. At least part of the carbon may be in the form of coarse lumps which are fed to the reactor via an entry duct in counter-current relation to evolved carbon monoxide which preheats and partially scrubs it.

Abstract: An apparatus for holding a spare wheel under the chassis of a motor vehicle in a horizontally suspended fashion, including a wheel holder supported at its one end on the outer surface of one longitudinal chassis member for both vertical and horizontal rotation to rotate its other end vertically and horizontally. A pin depends from a supporting member on the outer surface of the longitudinal chassis member and is connected to the one end of the wheel holder to permit at least horizontal rotation of the wheel holder. The vertical rotation of the wheel holder is effected by a rotative connective mechanism provided either at the one end of the wheel holder or between the pin and the one end of the wheel holder. A winch mechanism is provided for raising and lowering the other end of the wheel holder. According to one embodiment, the winch mechanism is positioned on the outer surface of the longitudinal chassis member, so that the wheel holder extends in parallel to the longitudinal chassis member for 90.degree.

Abstract: A process for the extraction of uranium from ores which is an improvement in the known "dry attack" treatment of uranium ores to an economical yet high rate of extraction. The process concerns solubilization of the uranium contained in the ores and consists of carrying out digestion of the mixtures of ore and reagent, with the possible addition of oxidizing agents. The process is carried out on an improved trough type of conveyor belt at predetermined conditioning of temperatures and humidity.

The strips are characterized in that each strip includes: (a) on its outer surface towards the road, molded-on profiles which are fitted with studs located on both the lateral shoulders and the central region; (b) on its inner surface which comes in contact with the tire, pointed rigid molded-on profiles specifically aligned with and/or provided immediately around the base of the studs. Additional molded-on profiles can be provided spaced about the remainder of the inner surface.

Abstract: A closure cap for bottles which is stamped from a blank and has a pair of tear assisting tabs thereon especially adapted for high speed bottling equipment and designed so as not to jam in the equipment. The tabs in the transport position form a V-configuration on their inner edges and their outer lateral edges are in parallel planes spaced apart a distance equal to the diameter of the cap; such construction permitting a following cap to enter between the tabs without riding up on the preceding cap.

Abstract: Process for recovering aluminum in the form of a specific acid sulfate from an initial solution containing aluminum in the form of dissolved aluminum sulfate hydrate in which the specific acid sulfate is of the formula Al.sub.2 (SO.sub.4).sub.3.0.5H.sub.2 SO.sub.4.11 to 12 H.sub.2 O and in which the initial solution is sequentially treated in a series of crystallizers, wherein successive crystallizers are maintained at a predetermined decreased generally fixed temperature such that in each crystallizer a state of supersaturation of aluminum acid sulfate exists and the parameters attendant operation of each crystallizer insure that a state of static equilibrium of precipitation of product is generally reached before the process solution/slurry is passed to a successive crystallizer, or filtered for recovery of product.

Abstract: An incentive spirometer for breathing control exercising of post-operative patients having flow varying capability. A patient breathing tube connects through a chamber in a base and through suction tubes to the upper end of a gauge tube in which a calibrated ball having a diameter substantially the same as the gauge tube is movable. Vent means in the gauge tube below the ball allow atmospheric air to act on the lower surface of the ball so that inhalation by the patient will cause the ball to rise in the gauge tube.

Abstract: A means of compensating the magnetic field induced by the adjacent line in series of high intensity electrolysis cells placed in a transverse direction. A compensating conductor traversed by a direct current which induces an antagonistic field neutralizing the parasitic field of the adjacent line is arranged along each line on the internal side and/or on the external side. Excellent compensation is achieved by regulating the intensity in each conductor and the distance between the conductor and the line.Application may be to series of igneous, very high intensity electrolysis cells for the production of aluminum.

Abstract: A process and apparatus for separating gaseous mixtures by a pressure swing adsorption technique. One or more adsorbent beds are employed which operate on a cycle comprising the successive steps of adsorption, vacuum regeneration, and backfilling. The pressure in the bed(s) during backfilling is sensed, backfilling is ceased when such pressure reaches a predetermined level, and the regeneration step is controlled to occupy a constant period of time. The described process is able to maintain a substantially constant output flow and product purity despite the changes in adsorption capacity of the bed(s) which occur under fluctuating ambient temperatures.

The vibrating means of the various markings are preferably made from identical comb-like members having teeth which are vibratory with different natural frequencies and of the type used in small music boxes. The different frequency codes may then be obtained by removing teeth in different combinations from the members used in the various markings. The markings may, for example, be arranged on dairy cattle, and the identification system may then be used in connection with a milk sampling system.

Abstract: A wooden workpiece is positioned on a saw table and introduced to a safety-back saw blade rotating in generally the same direction as the direction of introduction of the workpiece at the point of contact. The blade generates components of vertical and horizontal thrust of sufficient magnitude to self-feed either the workpiece or the saw, one relative to the other, at a rate compatible with the capability of the saw to cut the workpiece without generating sufficient thrust to propel the workpiece uncontrolled from the cutting and feeding operation.
