Abstract: Method and device for moving subsea rocks and sediments, also at significant depths, e.g. in connection with removal of protective rocks around subsea installations, where maintenance is to be conducted. The device comprises a rigid or at least partly flexible tubing (5) thorough which the masses (14) may be transported with the aid of a pressure gradient produced by an ejector nozzle (11) arranged externally in relation to said tubing. The nozzle (11) is fed with water from a water pump (12). The device further comprises a chassis (F) adapted to be transported along the (sea) bottom. The required power is arranged to be supplied through a cable (3) from the surface, while the tubing (5) preferably is arranged to be remotely controlled by a manipulator (9, 9").

Abstract: A medical procedure kit incorporates one or more surgical tools necessary to perform at least part of a medical procedure, along with a container having a quantity of a medical adhesive. Medical adhesives are useful as an alternate or an adjunct to surgical sutures and/or staples in wound closure, as well as for covering and protecting surface wounds such as lacerations, abrasions, burns, stomatitis, sores, minor cuts and scrapes, and other wounds. As such, the inclusion of such an adhesive into a composite medical procedure kit can be of great assistance to a medical doctor or surgeon by providing in single kit form, tools necessary to complete many medical procedures, without having to use multiple procedure kits. The adhesive may be independently sterilized and wrapped from the other surgical tools of the resultant kit, and then associated into kit form, or assembled and sterilized together as a unitary kit.  When the adhesive is incompatible with sterilizing procedures of the other components of the kit, the adhesive may be pre-sterilized and protected by a sterilization barrier that shields the adhesive from exposure to the sterilization process used to sterilize other tools of the procedure kit. The adhesive is preferably a 1,1-disubstituted ethylene monomer, such as an alpha-cyanoacrylate.

Abstract: La présente invention concerne un spectromètre de masse comprenant une source d'ions (10) munie d'une pluralité d'ionisateurs (20) d'échantillon à la pression atmosphérique montés sur sa surface antérieure (15). Chaque ionisateur d'échantillon (20) s'étend dans une zone d'échantillon correspondante (30) et la pointe de chaque ionisateur est montée à angle droit par rapport à la pointe correspondante du cône d'une pluralité de cônes d'entrée (50) possédant chacun un orifice d'entrée (40). Chaque cône d'entrée (50) s'ouvre à son tour sur un canal d'entrée comprenant une première et une seconde partie (60,70). Les deux parties du canal d'entrée sont séparées par une porte électrique (65). Les canaux d'entrée correspondant à chaque cône d'entrée (50) se rejoignent tous en un canal de sortie commun (90) vers un spectromètre de masse. En faisant fonctionner les portes (65) qui divisent les canaux d'entrée de manière adéquate, on parvient à obtenir une commutation rapide entre les échantillons analysés dans l'analyseur de masse.

Title: Process for producing catalyst-coated membranes and membrane-electrode assemblies for fuel cells
Inventor: HOHENTHANNER CLAUS-RUPERT
IPC: H01M8/02
Filed: 2003-02-28
Granted: 2011-06-07
Abstract: The present invention provides a continuous process for producing catalyst- coated polymeric electrolyte membranes and membrane electrode assemblies for fuel cells. The process of the invention uses an ionomer membrane having a polymeric backing film on the back side. After the first coating step, the membrane is dried, during which the residual solvent may be almost completely removed. After this, the polymeric backing film is removed and the back side of the membrane is coated in a second step. The front and back sides of the membrane can be coated by various methods, such as screen printing or stencil printing. Two gas distribution layers are applied to the two sides of the catalyst-coated membrane to produce a 5-layer membrane electrode assembly. The membrane electrode assemblies are used in polymeric electrolyte membrane fuel cells and in direct methanol fuel cells.

Abstract: In a method of producing metallic iron by reducing and melting a raw material, which contains an iron oxide-containing material and a carbonaceous reducing agent, by heating, the raw material for producing metallic iron is supplied after a powder and granular atmosphere control carbonaceous material is spread on a hearth of a heat-reducing furnace. In this case, a non-resolidificable carbonaceous material is used as the atmosphere control carbonaceous material, and thus a phenomenon that the powder and granular carbonaceous material is resolidified into a rice-cracker-like shape can be suppressed, thereby permitting solid-phase reduction with high efficiency and stable operationality.

Title: Method and apparatus for ozone sterilization
Inventor: ROBITAILLE SIMON
IPC: A61L2/24
Filed: 2002-11-08
Granted: 2007-01-23
Abstract: The sterilization method disclosed includes the steps of providing a sterilization chamber (10); - placing the article into the sterilization chamber; - equalizing the temperature of the article and the sterilization atmosphere; sealing the sterilization chamber; -applying a vacuum (40) of a preselected vacuum pressure to the sterilization chamber; - supplying water vapour (30) to the sterilization chamber under vacuum; - supplying ozone-containing gas (22) to the sterilization chamber; - maintaining the sterilization chamber sealed for a preselected treatment period; and -releasing the vacuum in the sterilization chamber; whereby a vacuum pressure is used which lowers the boiling temperature of water in the sterilization chamber below the temperature in the sterilization chamber. One or more ventilating cycles can be added to the preferred method for removing the remaining ozone and humidity from the sterilization chamber. Single cycle sterilization with ozone is more efficient and provides for a shorter sterilization cycle than with ETO and requires few changes in user habits.  Moreover, the ozone-based process in accordance with the invention is compatible for use with current packaging, such as sterile pouches and rigid containers. The sterilization process is simple and substantially avoids human errors caused by false interpretation and handling. The ozone sterilization method of the invention requires substantially no aeration or cooling down of sterilized instruments so that they can be used immediately following the sterilization cycle. This allows hospitals to reduce the cost of maintaining expensive medical device inventories.

In general, the mechanical coupling includes a hanger body or casing mandrel, a cone assembly journaled on the casing mandrel, at least one slot or groove in an outer wall of the casing mandrel, and at least one partially or fully annular slot on the inside surface of the cone assembly oriented to correspond with the groove(s) in the outer wall of the hanger body. At least one wire, or one or more bearings, is situated in the corresponding slot and the groove. The wire engages the flanks of the slot and groove sufficiently to resist axial or rotational movement of the cones relative to the hanger body.
