Abstract: "Method for the regeneration of ammoxidation catalysts" Regeneration of ammoxidation catalyst which is exhausted as a result of prolonged exposure to ammoxidation conditions, containing oxides of Mo, Bi, P, Fe, Co, Ni and possibly an alkali metal, particularly K, on a granular support, particularly silica, by means of a method including:
     - the impregnation of the granules of spent catalyst with an aqueous molybdic acid solution, or with an aqueous solution of partially or totally salified molybdic acid in the form of the ammonium salt, with a volume of impregnation solution less than the total pore volume of the catalyst subjected to regeneration;   - the drying of the impregnated granules at a temperature of from 100 to 200°C;   - the calcining of the dried granules at a temperature of from 250 to 450°C, solely when the impregnation is with an aqueous solution of partially or totally salified molybdic acid.   
     Under ammoxidation conditions, the catalyst regenerated in this manner displays characteristics of activity, selectivity and of mechanical strength similar to those of the fresh catalyst.

IPC: B01D53/50
Filed: 1986-01-15
Abstract: In the desulphurisation of waste gases by injection of suspended calcium hydroxide, high efficiency is achieved only at relatively low treatment temperatures which in turn cause corrosion problems, since the temperature in the downstream plant sections (e.g. dust precipitator, stack) drops below the dew point. The waste gases must therefore in many cases be reheated. It is proposed to recover the energy required for heating the waste gases from the oxidation of the calcium sulphite formed in the desulphurisation, to calcium sulphate. For this purpose, the calcium sulphite-containing residues arising in the gas purification unit are oxidised in a separate furnace, then dedusted and either admixed directly to the waste gases to be heated up or used for indirect heating by means of heat exchangers. <IMAGE>

Abstract: An offset lithographic press, as commonly found in the newspaper industry, is provided with an airless, pulsed spray dampening system for simplified, automatic control of the ink/dampening fluid balance. The dampening system is constructed in accordance with several critical parameters, including the center-to-center nozzle spacings, nozzle to adjacent roller spacings, as well as the frequency of pulses per minute, the duration of each pulse, and the pressure of the dampening fluid. Construction of a dampening system in accordance with the critical parameters enables the press to be operated with a minimum of user intervention, and the relatively small spacing between the nozzles and the adjacent rollers is such that the dampening system can be mounted adjacent the aisles between the press units for facilitating maintenance thereon. The system directs a continuous, carefully controlled supply of dampening fluid to the plate so that the latter can be satisfactorily used with a minimum of fluid and does not experience moisture variations cycling between wet and dry conditions. A spray bar provided with eight nozzles oriented in parallel relationship to the longitudinal axis of an associated dampening system roller is detachably mounted to the frame and can be readily removed for repair or replacement.

Abstract: Control of the Fermi level pinning problem and the production of flat band surface performance in compound semiconductors is achieved by providing a cationic oxide free of anionic species on the surface of the semiconductor for flat band performance and with a localized inclusion of some anionic species for barrier performance so that oxide and metal work function responsiveness is available in structure and performance in MOSFET, MESFET and different work function metal FET structures. A cationic gallium oxide is produced on GaAs by oxide growth during illumination and while being rinsed with oxygenated water. The oxidation is used to produce both anionic and cationic species while the rinsing process selectively removes all the anionic species.

IPC: G01M9/06
Filed: 1987-09-17
Abstract: A passive load mitigation system for supporting transducers on a body moving through a fluid stream is described. According to the invention, a streamlined aerodynamic surface for supporting the transducers is attached to the body via a pivot axis. The axis supports the surface in a torsionally unrestrained manner in at least one rotational degree of freedom about the pivot axis. Therefore, as the body moves through the fluid stream, the surface remains substantially parallel to the plane of the stream. Aerodynamic stability is ensured by forming the surface with substantially trapezoidal or parallelogram shaped sidewalls and by mounting the surface on the pivot axis such that the surface's aerodynamic center is located downstream of the pivot axis. Flutter is prevented or substantially reduced by increasing the surface's bending stiffness or by incorporating ballast weights on a tip pod attached to a portion of the surface.

Abstract: Reference beam deflection command values are assigned to respective pinholes at two diametrically opposite corners of a cathode ray screen. The pinholes sense actual beam position by transmitting light via respective fiberoptic cables to a detector arrangement remote from the electrostatic fields at the screen. Command values corresponding to actual beam alignment with the pinholes are determined and compared to the preselected reference beam deflection values, to produce corrections required to compensate for image scaling and/or center drift errors. With stroke type image generation, special beam search patterns are generated in the vicinity of the pinholes to activate the detector arrangement.
