Title: Apparatus and Method for Forming Heat Treating Atmospheres
Inventor: NAYAR HARBHAJAN S
IPC: C21D1/76
Filed: 1997-03-04
Abstract: The present invention is directed to a method for forming a heat treating atmosphere in which a nitrogen rich gas containing small amounts of oxygen is preheated.

Title: Pince chirurgicale ayant une ouverture longitudinale par laquelle le tissu immobilise fait saillie
Inventor: YU GEORGE W
IPC: A61B17/122
Filed: 1995-11-21
Abstract: La présente invention concerne une pince chirurgicale (50) ayant un côté (52) avec deux pattes et un côté (62) avec une seule patte. Lorsque la pince chirurgicale est fermée, le mouvement de la patte unique vers les deux pattes déplace le tissu immobilisé vers une ouverture longitudinale (58) entre les deux pattes (54) (56) de l'autre côté (52). Pour augmenter la surface de préhension de la pince, la surface de préhension de la patte simple a la forme d'un coin arrondi avec des bords arrondis (c'est-à-dire non coupants) qui sont parallèles aux côtés internes des deux pattes. La forme en coin arrondi permet d'éviter de couper le tissu. Lorsque la pince chirurgicale est engagée avec le tissu pour l'immobiliser, un plan du tissu est déplacé dans la région de serrage, ce qui augmente la force nécessaire pour désengager la pince du tissu immobilisé.

Patent CA-2233931-A1 (CA)
Inventor: KANER AVIGDOR
IPC: G07B15/02
Filed: 1996-07-29
Abstract: A vehicle parking network comprises a transmitter-responder device (TRD) for each subscriber and a complementary box which can be coupled to the TRD and only to it, and permits it to communicate with a central computer. The complementary box is provided with identification marks that can be scanned from the outside and includes a microcontroller, memory means and timing means. Once the vehicle is parked, the TRD is used to obtain from the computer a parking authorization and an allowed parking time. Then a legitimate parking sign is displayed and the parking time is downcounted until the allowed time has been completed or until the vehicle leaves the parking space. If communication with the computer cannot be established, the complementary box carries out an assumed parking procedure, stores its data in a buffer memory, and later transmits them to the computer for verification and registration. The computer communicates the data of each parking to the Public Authority charged with collecting the parking fees. Examples of TRD's are cellular phones, message recorders, pagers, private alarms and vehicle location units (VLU). If a VLU is used, the central computer obtains vehicle location data from the control center of the vehicle location system, monitors the vehicle position, and carries out the parking procedure.

Abstract: The invention relates to a method of converting hydrocarbons. According to the method, a gaseous or liquid hydrocarbon feed is passed into a circulating fluidized-bed reactor, wherein the feed is converted at a high temperature under the influence of particulate matter kept in a fluidized state, and the converted hydrocarbon products are removed from the reactor in a gaseous phase. According to the invention, a circulating fluidized-bed reactor (1-3; 41-43) is used having an axially annular cross section and being equipped with a multiport cyclone (14,17;  52,63) for the separation of the particulate matter from the gas-phase reaction products. The reaction space comprises an intershell riser space (L3; 50) formed between two concentrically located cylindrical and/or conical envelope surfaces. The separation of particulate matter from the gas-phase reaction products is performed by means of a multiport cyclone equipped with louvered vanes (14; 63).
