Filed: 1995-12-18
Abstract: A reactor for catalytic dehydrogenation of dehydrogenatable hydrocar-bons, in particular C3 and/or C4 hydrocarbons, in a hydrocarbon-containing stream, with selective oxidation of hydrogen. The reactor comprises seri-ally connected in the flow direction of the hydrocarbon-containing stream: a first catalyst zone (2), an oxygen admixing zone (3) provided with a means (5) for separate feeding of an oxygen-containing gas into the hydrocarbon-containing stream, and a second catalyst zone (4).

The means (5) for feeding oxygen-containing gas is designed to feed said gas with a flow velocity which is at least 1 m/s and is up to 200 times higher than the flow velocity of the hydrocarbon-containing stream in the oxygen-admixing zone.  The oxygen-admixing zone (3) is free of catalyst at least in the region adja-cent to the oxygen feeding means (5).

Inventor: MEADOR JAMES W
IPC: A61B17/22
Filed: 1996-06-07
Abstract: This invention is a pericardial centesis apparatus (100) and method for accessing the pericardial space. The invention consists of inserting a percutaneous tube (104) whose tip has a hole (123) which is positioned over and contacts the anterior pericardium. Introducing a vacuum within said tube (104) forms a pericardial bleb within that hole. A  guided needle (124) within the tube is advanced to puncture the pericardial bleb while avoiding contact with the epicardium. A hollow filament or electro-cardial lead or flexible guide wire (114) within said needle can then be advanced into said pericardial cavity. The guide wire (114) may be used to guide an intra-pericardial catheter into the pericardial space for injection or infusion of selected therapeutic agents into the pericardial space to treat various heart and blood vessel diseases. Controlled drug release materials can be injected through said needle (124) for the slow and/or sustained delivery of said therapeutic agents into said pericardial cavity.

Title: Inter-vertebral implant
Inventor: COTTLE WILLIAM
IPC: A61F2/00
Filed: 1996-10-03
Abstract: The inter-vertebral implant consists of a frame-like cage enclosing a space, with a top and bottom surface, two side surfaces, a front and a rear wall. The top and bottom surfaces have a plurality of perforations, the total area of which amounts to 40 to 55 % of the total area of said surfaces. The individual area of a single perforation is at most 20 % of the total area of the top and bottom surfaces.      The ratio VH/VK between the volume VH of the space and the total volume VK of the cage is in the range from 70 to 90 %.      The cage is substantially wedge-shaped with top and bottom surfaces diverging towards the front wall. This gives the advantage that, owing to the large bone bearing area of the top and bottom surfaces, the implant is prevented from sinking into the end plates of the body of the vertebra.

Patent CA-2240363-A1 (CA)
Inventor: SIDRIM FERNANDO ANTONIO COSTA
IPC: E21B43/12
Filed: 1997-01-29
Abstract: This invention relates to a method and equipment to assist the flow of offshore production of hydrocarbone mixtures containing a high concentration of gas. A primary separating vessel (52) is used and production is diverted to it. This vessel (52) is designed to allow primary separation of the gas, which flows to the gathering centre (63) via a special line (56). Within the primary separating vessel (52) there is a U-shaped length (53) of pipe whose arms are connected to two flow lines (57 and 58) which extend to the gathering centre.  A mechanical interface (70) driven by high pressure gas periodically travels along these lines (56, 57 and 58), carrying with it to the gathering centre (63) the volume of liquid phase which has accumulated in the lines. If liquid phase passes into the gas flow line (56), a mechanical interface (70) can be passed along this line to remove the volume of liquid which has accumulated within it.
