Title: Procede de preparation d'un compose ferrique a base de sulfate et d'hydroxyde
Inventor: JAFVERSTROM STEFAN
IPC: C01G49/14
Filed: 1994-12-29
Granted: 2007-03-27
Abstract: L'invention se rapporte à un procédé de préparation d'un composé ferrique pur et solide, à base de sulfate et d'hydroxyde, tel que de l'hydroxysulfate ferrique ou de la jarosite de sodium, ce procédé comprenant les étapes suivantes: a) on prépare un sel ferrique de sulfate ou de chlorure, b) on prépare une solution aqueuse acide comprenant soit des ions sulfate et des ions ferriques, soit des ions sulfate, des ions chlorure et des ions ferriques, c) on maintient cette solution aqueuse acide pendant 2 à 12 heures à une température comprise entre 60 et 220 ~C afin d'obtenir par hydrolyse un composé ferrique solide de sulfate et d'hydroxyde, tel qu'un hydroxysulfate ferrique ou de la jarosite de sodium, et d) on sépare de la solution aqueuse acide le composé ferrique de sulfate et d'hydroxyde, tel que l'hydroxysulfate ferrique ou la jarosite de sodium. Les procédés de préparation de l'hydroxysulfate ferrique et de la jarosite de sodium diffèrent sensiblement seulement en ce que pour la préparation du jarosite de sodium, on utilise une solution aqueuse acide qui, outre les ions sulfate ou ferriques, ou les ions sulfate, chlorure et ferriques, contient également un composé de sodium soluble dans l'eau, auquel cas on obtient de la jarosite de sodium au lieu de l'hydroxysulfate ferrique, lors de l'étape d'hydrolyse c) du procédé.

Patent CA-2208415-C (CA)
Inventor: ASTROM BO
IPC: H04M3/42
Filed: 1995-12-15
Granted: 2006-06-06
Abstract: A system and method is provided for controlling the signalling between the subscriber of a mobile station and an external service node such as a message center. The control of the signalling is carried out by using unstructured supplementary service data (USSD) which is analyzed by a USSD handler of a home location register which invokes a transparent transfer to external service node (TTEN) application when the USSD does not correspond to a service defined within the home location register. The TTEN application establishes a dialog with the subscriber of the mobile station and the desired external service node by using USSD. This allows the subscriber of the mobile station to access all message services by sending one service code.      Also, the operator is not busy while accessing the services and any incoming calls may be answered while accessing the services.

Abstract: A fluid valve (10) has a housing (12) formed by first and second halves (14, 16) which combine at mating surfaces (26) to form a cavity (22) with an inlet (18) in the first half and an outlet (18) in the second half. The mating surface of each half includes a notch (32) extending between an outer edge of mating surface and the cavity, and includes an annular recess (28) around the cavity. A pad (40) is formed on each mating surface between the cavity and the annular recess, and has a groove (42) that forms a bushing when the first and second units are connected. A butterfly valve member (82) is located within the cavity and is mounted on a valve stem (76). The valve stem has an end that rides in the bushing and a portion that passes through the notches in the housing halves. An annular seal (44) fits within the recesses to prevent fluid leakage between the two housing halves and also seals around the valve stem portion. In addition the butterfly valve member engages the seal in a closed state of the valve.

Abstract: Apparatus for forming elongated metal cans (32) from relatively short cups (30) by utilizing a reciprocating ram (24) to drive the cups one at a time through a die pack (33a-33d), is provided with a continuously rotating feed (41) that transfers the cups from the exit of a gravity feed chute (26) to a receiving station (25) where each cup is indexed for engagement by the ram as it moves forward in its working stroke. The feeder rotates through one complete revolution for each forward-return cycle of the ram and during each revolution thereof a pocket (40b) in the feeder receives a cup from the chute, which cup then moves downstream through a guideway to a receiving station. A tensioner device (100) is used to keep the cup seated fully on the registry formation during the initial engagement of the cup by the ram while the latter moves forward in its working stroke.

Abstract: Sperm, oocyte, and embryo survival and function is improved in vivo or in vitro by the use of a polysaccharide containing arabinose, galactose and/or hexuronic acid. In particular, a nonspermicidal lubricant containing such a polysaccharide (e.g., gum arabic, pectin, or galacturonic acid) increases the fertilization potential of the sperm during coitus, artificial insemination or sperm collection. Similarly, a freezing medium containing a polysaccharide containing arabinose, galactose and/or hexuronic acid enhances sperm, oocyte, or embryo viability.

Abstract: Un système de commande permettant, dans un réseau ATM, de maîtriser les flux (202, 212, 226) de cellules de données et les cellules de gestion de flux allant d'un certain nombre de sources à une destination par des connections passant par un élément de réseau (212). Les cellules de gestion de flux sont renvoyées de leur destination à leurs sources respectives par un élément de réseau. Cet élément de réseau est susceptible d'encombrements en raison de la concurrence entre les connections, ce qui nécessite une file d'attente des connections. Les cellules de gestion de flux ont un champ de débit explicite pour une valeur de débit explicite servant à limiter le débit maximum autorisé de cellules à partir de la source à une valeur spécifique. Une fonction d'exploitation (230) utilise les écarts par rapport à une valeur de débit disponible pour les cellules à moindre priorité et par rapport à une référence de longueur de queue constituant une longueur de queue acceptable pour calculer une valeur modifiée de débit explicite comme fonction de ces écarts. Cette valeur modifiée de débit explicite est introduite dans le champ de débit explicite des cellules de gestion de flux vers l'amont (226).

Inventor: WEBER PETER BERNHARD
IPC: B09B3/00
Filed: 1997-04-21
Granted: 2005-08-23
Abstract: A method for safely treating and disposing of infectious biomedical waste and other hazardous materials is disclosed. The method involves alkaline hydrolysis of infectious agents contained in regulated medical waste or hazardous waste solutions. The infectious waste is immersed into a highly basic solvent which is then heated. The material containing the infectious agents is allowed to remain within the heated solvent until the hydrolyzable matter is fully digested, thereby forming a sterile solution and sterile solid waste. The sterile solution and solid waste may then be disposed of through standard means, such as in a sanitary sewage system or local landfill facility. The method also provides for the treatment of lipid soluble hazardous material contained in the regulated medical waste.

Abstract: The automatic analyzer for the assay of liquid samples comprises an exchangeable mixing chamber unit (34) whose mixing chamber (14) is tapered toward the bottom and is provided with an outlet (18) which is followed by a bore (19) which connects the mixing chamber (14) to an outlet opening (20). An abrupt transition (13) is formed between said bore (19) and the outlet opening (20) for the analyzed liquid. Said abrupt transition (13) is a restriction which serves as a collecting trap for disturbing particles (23), e.g. coaguli, which might lead to undesirable obstructions elsewhere. Those particles which cannot be flushed away laterally by another outlet opening (17) are eliminated by removing the mixing chamber unit (34) from the base unit (35) in few operations and blowing it through. A sealing ring (49) serves for a tight seal between the plane bottom (41) of the mixing chamber unit (34) and the connection (47). A fluid sensor (50) is provided in order to detect the sample liquid flowing through this connection.
