Patent EP-0045590-A1 (EP)
Inventor: SWALES DANVERS A
IPC: C01G37/033
Filed: 1981-07-21
Abstract: Chromium trioxide is made by reacting sodium dichromate with sulphuric acid in an aqueous reaction mixture, evaporating the resultant liquor to cause crystallisation of most of the chromium trioxide and to cause the concentration of sodium sulphates to be close to but below that at which sulphate crystals start to form, and separating the chromium trioxide crystals from the evaporated liquor. The liquor may then be cooled so as to cause crystallisation of sodium sulphates, generally as sodium bisulphate, and the resultant liquor, after separation of the crystals, may be recycled to the reaction mixture containing dichromate and sulphuric acid.

Abstract: Nouveau type de moteurs a explosion ou a combustion interne, comportant deux rotors l'un dans l'autre, le tout dans un stator. Les deux rotors ont la meme vitesse de rotation, mais tournent autour d'axes de rotation differents. Ces axes sont paralleles et non confondus. Des cloisons, escamotables dans le rotor interieur, delimitent avec l'exterieur du rotor interieur et l'interieur du rotor exterieur des chambres de combustion etanches entre elles. De ce fait, un lubrifiant peut circuler du rotor interieur au rotor exterieur par l'intermediaire des cloisons et etre evacue par des ouvertures amenagees sous les cloisons a cet effet. Des ouvertures d'echange de gaz sont pratiquees sur le rotor exterieur, coincidant avec des lumieres d'admission et d'echappement, puis avec un trou filete pouvant recevoir un dispositif d'allumage ou d'injection pratiquees dans le stator a un moment de la rotation. Le stator est ajuste au rotor exterieur de telle facon qu'il obstrue ces ouvertures lorsqu'il n'y a pas coincidence. Le moteur birotatif est egalement muni d'un dispositif de compression des gaz d'admission et de tout autre dispositif necessaire au bon fonctionnement d'un moteur a explosion ou a combustion interne.

Abstract: Ein Verfahren zur Entfernungsermittlung eines Zielgegenstandes aus der Laufzeit eines Messlichtimpulses vom Messort zum Zielgegenstand und zurück erfordert ene exakte zeitliche Zuordnung zwischen Sendezeitimpuls und Beginn bzw. Empfangszeitpunkt und Ende der Laufzeitmessung. Hierzu wird bisher ein vom Sendelichtimpuls abgezweigter Referenzlichtimpuls praktisch verzögerungsfrei einem eigenen Empfänger zugeführt, dem wie dem Empfänger für den reflektierten Messlichtimpuls ein eigener Empfangskanal nachgeschaltet ist, dessen Ausgangssignal die Laufzeitmessung beendet. Die beiden Empfangskanäle besitzen üblicherweise verschiedene Signallaufzeiten, deren unterschiedliche Schwankungen auch mit grossem technischen Aufwand nicht völlig eliminierbar sind. Zur Lösung der daraus resultieenden Aufgabe, nämlich ohne grossen Aufwand sehr hohe Messgenauigkeiten zu erzielen, werden Messlichtimpuls (15) und Referenzlichtimpuls (28) demselben Empfänger (16) zugeleitet. Die Schwankungs- und Drifterscheinungen dieser einkanaligen Anordnung sind in dem kurzen, zwischen den Empfangszeitpunkten zweier zusaminengehöriger Lichtimpulse liegenden Zeitraum vernachlässigbar. Für sehr kurze Messentfernungen ist der Referenzlichtimpuls auf einen zweiten Lichtweg (34, 35) mit einer Verzögerung wenigstens gleich dem Zweifachen der Freiwerdezeit des Empfangskanals umschaltbar.

Abstract: A hydrostatic transmission such as for a vehicle comprises a variable speed prime mover (10), a variable displacement pump (20) powered by the prime mover (10), a fluid motor (30) powered by the variable displacement pump (20) and, in accordance with the invention, a control device (140) which senses the speed of the prime mover (10) and regulates the operation of a control cylinder (60) of the variable displacement pump (20) in accordance therewith so that the speed of the fluid motor (30) is not only responsive to speed changes in the operation of the variable displacement pump (20) directly attributable to changes in speed of the primp mover (10) driving the variable displacement pump (20) but also responds to displacement changes in the variable displacement pump (20). A fixed pump (90) powered by the prime mover (10) develops a fluid flow proportional to the speed of the prime mover (10) and this is converted into a corresponding mechanical signal by means of a series orifice ( 1 00) which develops a pressure differential, proportional to the fluid flow of the fixed displacement pump (90), which sets the operation of a piston and cylinder arrangement (142). The said mechanical signal determines the setting of a compensator valve spool (156) which, in dependance upod the position of an associated sleeve (160) determines the supply of high pressure fluid to the spool (176) of a servo arrangement having a control sleeve (182) which is mechanically linked with the displacement control element (40) of the variable displacement pump (20) and furthermore provides a camming surface for a cam follower (198) which in turn acts upon the compensator valve sleeve (160). By this means, a mechanical feedback signal representative of the displacement of the variable displacement pump (20) is transmitted to the control means of the variable displacement pump (20) to maintain the pump displacement proportional to the speed of the prime mover (10).

Abstract: Two or more stimulable phosphor sheets carrying radiation images of an object stored therein under conditions different from one another are scanned with stimulating rays to convert the radiation images into light, which is photoelectrically read out and converted into digital image signals. The digital image signals are subjected to subtraction between corresponding picture elements of the images, thereby to obtain a signal for forming an image of a specific structure of the object. Markers for providing reference points or lines are recorded together with the radiation images in a positioned fixed with respect to the radiation images to correct the deviations among the radiation images prior to the subtraction. To improve the quality of the subtraction image, image size reduction is conducted on the radiation image before or after the subtraction.
