Title: Device on board a moving vehicle to obtain signals representative of the relative speed of the vehicle relative to an ambient fluid
Inventor: BEIGBEDER GERARD
IPC: G01P5/00
Filed: 1990-06-22
Granted: 2000-08-01
Abstract: The device uses fringe laser diode anemometers which, from the beams coming from one or more laser diodes, for measuring volumes made of interference fringes. The component of the relative speed of an aircraft in a direction perpendicular to the plane of these fringes is deduced from the modulation that the dust particles cause in the signal of the photodetector of each anemometer during their passage in the measuring volume of this anemometer. By joining two anemometers with the measuring volumes whose planes of the fringes are, for example, orthogonal, it therefore is possible to determine two components of the relative speed vector and therefore to determine, for example, this relative speed in the longitudinal vertical plane of the aircraft, and to deduce from it the angle of incidence of the aircraft.

Granted: 1999-12-07
Abstract: A one-piece casing (20) comprising a bottom (22) and a shell (24) formed with a cylindrical bore (26) houses a piston (30) for hydraulic actuation of a brake. For mechanical parking brake actuation, a shaft (34) is supported in the bottom (22) of the casing and a ramp arrangement (50) is rotatable by the shaft, thereby being displaceable axially away from a ramp arrangement (40) which is secured to the casing. Two strut members (60,64) which are screwed together constitute an adjustable strut between the axially adjustable ramp arrangement (50) and the piston (30). A return spring (90) is positioned under axial bias between a thrust bearing (92) secured to the casing and a thrust bearing (58) at one of the two strut members (60). The thrust bearing (92) which is secured to the casing is formed at an insert (84) by which one of the strut members (60) is guided non-rotatably. The ramp arrangement (40) which is secured to the casing as well as the insert (84) are retained against axial displacement in the casing (20) by a common fastening member (96) and are prevented from rotating by a common twist preventing means (42).

Title: Current averaging data separator
Inventor: WAHLER RICHARD
IPC: H03L7/089
Filed: 1991-05-06
Granted: 1994-04-05
Abstract: Abstract Of The Disclosure A data separator for use in synchronizing data derived from a floppy disk or similar data source provides a variable net gain or loss of charge to vary the frequency of a voltage-controlled oscillator in accordance with the relative position of the data with respect to the clock until data centering or synchronization is achieved. The net charge is derived from a charge pump circuit that is controlled by a charge pump-up signal whose duration is proportional to the detected phase difference between the data and the clock, and a charge pump-down signal whose duration is one clock cycle.  When the data pulse is centered within a clock cycle, the duration of a pump-up signal is one half that of a pump-down signal.

IPC: C07C51/43
Filed: 1992-01-30
Granted: 2002-10-08
Abstract: Terephthalic acid is produced by oxidation of para xylene, purified in an aqueous phase and recovered by precipitating a purified product from the aqueous phase, the aqueous phase mother liquor is then cooled or evaporated to produce a further less pure precipitate and a second mother liquor and the less pure precipitate is returned to the reaction medium and/or the water of the second mother liquor is used to dissolve the crude solid and/or the second mother liquor is treated to recover water which is used to wash the precipitate recovered from the aqueous solution. The process produces better yields of terephthalic acid, reduces the use of water and reduces problems in the disposal of polluted waste water.

Abstract: Des matériaux métallurgiques résiduels, qui ne sont pas écocompatibles avec des applications comme le déversement en décharge contrôlée ou le déversement à ciel ouvert ou dans des bassins recouverts de plastique, en raison de la contamination de la nappe phréatique, peuvent être traités pour récupérer les éléments utiles (Zn, Cd, Pb, Ag), et fixer les éléments toxiques (As, Sb, Bi) sous forme de scories écocompatibles.  Les matériaux résiduels renferment : a) au moins un composé du fer, qui peut être un oxyde simple ou mixte de fer (hématite, goethite, ferrites et jarosites); b) au moins un métal lourd (Zn, Pb, Cd), récupérable dans des conditions fortement réductrices et par volatilisation; c) au moins un élément toxique (As, Sb, Bi), séparé du fer et stabilité dans la matte ou le speiss.

Des conditions fortement réductrices à la surface de la masse en fusion (22) entraînent la volatilisation de Zn, Pb et Cd.  Les éléments toxiques (As, Sb, Bi) sont stabilisés dans la couche de matte ou de speiss de la masse en fusion (22), avec un peu de Zn, un peu de Pb, Ag. Au, Cu, Ni et Co.   mesure que la masse en fusion circule autour de l'extrémité de la lance (24) et de la zone de combustion oxydante qui y est associée, les éléments toxiques (As, Sb, Bi) sont oxydés et volatilisés, et s'échappent avec les gaz de carneau par la tuyauterie d'aspiration (18), soit sous forme de métal ou (par oxydation au-dessus de la masse fondue) d'oxyde.  Le four (10) possède un trou à scories (26), d'où les scories écocompatibles, à faible teneur en éléments toxiques, peuvent être soutirées périodiquement ou en continu.  La lance (20) est protégée du milieu environnant par une couche protectrice de scories (28), se formant lors du procédé.
