Title: Sterilizer with vacuum-assisted air removal
Inventor: CIORACA DORIN
IPC: A61B50/33
Filed: 2000-04-06
Abstract: A sterilizer for medical instruments is compact and designed to be placed on a table top. The sterilizer provides includes a cavity for receiving a cassette holding the instruments to be sterilized. A stream circuit provides steam to the cassette for sterilization, and the time required for sterilization is reduced by withdrawing air from the cassette by application of a vacuum.

IPC: H04J13/00
Filed: 2000-10-19
Abstract: This invention relates to a method and arrangement for controlling transmission power in a mobile communications system, and to a network element. In the method according to the invention a certain target level is defined for a value representing the quality of a signal, which target level should be reached by the received signal. According to the invention this target level is advantageously limited so as to be smaller than or equal to a first predetermined limit value and/or greater than or equal to a second predetermined limit value. In accordance with the invention the quality of the signal may be measured e.g. by means of an SIR  value. In the method according to the invention the quality of the received signal is checked and, based on the check, a first SIR  target level is given to a comparing element (21). By means of the comparing element (21) it is ensured that the said first SIR target level falls within predetermined limits. Based on the comparison, a final SIR  target level is given to a power control element (12) which produces a power control signal in order to adjust the transmission power.

Abstract: L'invention porte sur des procédés et sur un appareil de fabrication de dispositifs de petite échelle tels que des dispositifs à échelle micronique et submicronique, y compris des dispositifs à échelle nanométrique. Le transport électronique de dispositifs à composants mobiles s'effectue dans un milieu fluidique en direction d'un endroit cible désiré sur un substrat ou carte-mère. Les forces utilisées sont la force électrophorétique, la force électro-osmotique, la force électrostatique et/ou la force diélectrophorétique. Selon une réalisation préférée, des forces électro-osmotiques exemptes de champ sont utilisées soit seules, soit avec d'autres forces. Ces forces peuvent être utilisées seules ou en combinaison avec également d'autres forces telles que des forces fluidiques, des forces mécaniques ou des forces convectives thermiques. Selon cette réalisation préférée, des dispositifs qui, par leur taille, poids et/ou densité, ne peuvent pas être effectivement transportés par transport électrophorétique, peuvent être transportés sur la surface du dispositif cible ou carte-mère via un écoulement de fluide électro-osmotique. Le transport peut être effectué au moyen d'électrodes de commande de manière à transporter le dispositif à composants vers d'autres électrodes de connexion. Selon certaines réalisations, les électrodes de connexion peuvent être utilisées soit seules, soit en combinaison avec des électrodes de commande afin de transporter électroniquement le dispositif à composants vers les électrodes de connexion. Une électrode de commande peut être utilisée pour placer le dispositif à composants à proximité des électrodes de connexion, ces électrodes de connexion étant ensuite utilisées pour générer un écoulement électro-osmotique de façon à créer une pression fluidique sur le dispositif à composants en direction des électrodes de connexion. On peut ainsi réaliser un mouvement série ou un mouvement parallèle des dispositifs à composants. L'invention porte également sur des procédés devant être utilisés dans un environnement à faible gravité de sorte que les modes de transport électronique puissent être utilisés avec des dispositifs à composants qu'on ne pourrait réussir à réaliser dans un environnement gravitationnel normal.

Patent CA-2391653-A1 (CA)
Inventor: SCHWERT SIEGFRIED
IPC: B29C63/36
Filed: 2000-11-28
Abstract: The invention relates to a method for lining a pipe conduit (3) with a textile tubing (4) that adheres to the inner walls of the pipe conduit by means of an adhesive. According to a first aspect of the invention, the coated textile tubing is filled with a long pot life adhesive and the textile tubing is turned inside out while introducing it into the pipe conduit or channel.  Substantially simultaneously with introducing the textile tubing a fast-curing adhesive is applied to the inner wall of the pipe conduit in as short a distance as possible to the end (9) of the tube moving through the pipe conduit. The introduced tubing is then subjected to an inner pressure so as to force it against the inner wall of the pipe conduit until the fast-curing adhesive between the tubing and the inner wall of the pipe conduit has cured.  According to a second and third aspect of the invention, the pipe conduit is not filled with a long pot life adhesive. Instead, according to the second aspect, a textile tubing is used that has been impregnated thoroughly.  According to the third aspect, a coated tubing is used. The pressure required for forcing the textile tubing against the pipe conduit is so high that the fast-curing adhesive fills out the fabric completely without trapping any air.  According to the fourth and the fifth aspect of the invention, the textile tubing is simply filled with an adhesive under conditions under which curing does not at all or only slowly take place before the textile tubing is introduced into the pipe conduit. The conditions required for the adhesive to cure quickly are created not before the textile tubing has been turned inside out.
