Title: Procede et dispositif de sterilisation a l'ozone
Inventor: SIMARD MARIO
IPC: A61L2/20
Filed: 2000-01-24
Abstract: La présente invention concerne un procédé de stérilisation qui, après mise en place d'une enceinte de stérilisation, consiste à placer un article dan cette enceinte, à fermer de manière étanche l'enceinte, à la mettre sous vide à une pression prédéterminée, à alimenter l'enceinte sous vide en vapeur d'eau puis en gaz contenant de l'ozone, à maintenir étanche l'enceinte durant une période de traitement prédéterminée, et à faire remonter la pression dans l'enceinte de stérilisation. Dans ce procédé on utilise un vide permettant d'abaisser le point d'ébullition de l'eau à une température inférieure à celle régnant dans l'enceinte. On peut ajouter au procédé préféré de l'invention un ou plusieurs cycles de ventilation permettant d'éliminer de l'enceinte de stérilisation l'ozone et l'humidité qui restent. Un cycle unique de stérilisation avec de l'ozone est plus efficace et permet un cycle de stérilisation plus court qu'avec l'oxyde d'éthylène (EtO) et ne demande que peu de changement dans les habitudes d'un utilisateur. De plus, le procédé à l'ozone selon l'invention peut être utilisé avec les emballages courants, tels que des poches stériles et des contenants rigides. Le procédé de stérilisation est simple et permet pratiquement d'éviter des erreurs humaines de fausse interprétation et de manutention. Ce procédé de stérilisation à l'ozone ne requiert pratiquement pas d'aération ou de refroidissement des instruments stérilisés, ce qui permet leur utilisation immédiatement après le cycle de stérilisation. Les hôpitaux peuvent ainsi réduire les coûts de maintien de stocks de dispositifs médicaux chers.

Abstract: A method and apparatus for injecting a gaseous fuel into a combustion chamber of an internal combustion engine employs a combination of operating modes. First, one of a low load and a high load mode of operation is selected during the operation of the internal combustion engine. Low load and high load modes are distinguished by the combustion characteristics of an amount of fumigated fuel added to the combustion chamber. Fumigated fuel that supports combustion will cause high load to be selected. Fumigated fuel that does not support combustion will cause low load to be selected. A directly injected amount of fuel is provided under low load. Under high load, a directly injected quantity of fuel can be added when the piston is near top dead center to allow the engine to meet load requirement above that provided by the fumigated fuel.

Title: Optically powered sensor arrangements
Inventor: ANDRESEN RICHARD P
IPC: G01D5/24
Filed: 1990-03-05
Abstract: ABSTRACT OF THE DISCLOSURE     An  optically  powered  sensor  arrangement  comprises  a plurality  of  sensors  which  are  interconnected  to  an optical  bus  to  communicate  with  a  central  controller.         Each of the sensors receives optical energy from the bus and  uses  a  photo-diode  array  to  convert  the  received optical energy into electrical energy which is stored in a capacitor.   Each sensor  includes a  transducer  in the form of a capacitance device,  such as one  in which the capacitance  varies with  liquid  level.   In  addition,  a fixed  reference  capacitance  is  provided.   Under  the action of a timing and sequence control, and as energised by the stored electrical energy in the capacitor, a pulse encoder  produces,  in  sequence,  two  integrated  outputs, one dependent on the capacitance value of the transducer and the other dependent on the capacitance value of the reference capacitor.  The integrated outputs are compared with predetermined fixed levels so as to produce a series of short-duration pulses from whose time separation the capacitance value of the transducer can be derived, and thus  the  liquid  level.   These  pulses  drive a  light emitting diode  to  produce  corresponding  optical  pulses which are transmitted to the central control.
