Title: Combined laser and plasma-arc processing torch and method
Inventor: BOGACHENKO EVGENY
IPC: B23K26/20
Filed: 2000-07-05
Abstract: A combined laser and plasma-arc welding torch, which joins features of separate laser and plasma-arc welding devices in a single tool. A laser beam is directed by an optic system to be co-linear with the central axis of a plasma-arc torch. The laser beam passes through a group of electrodes, whose longitudinal axes are disposed at an acute angle to the torch central axis on the generatrix of a cone, the apex of which lies on the torch central axis close to the section plane of a constricting nozzle, and the base of which faces the main body of the torch. The electrodes may be both cathodes, or anodes, or cathodes and anodes. The welding torch may be additionally provided with a mechanism for additional constricting and stabilization of a plasma jet. Gas is forced through a chamber having the electrodes and nozzle at the chamber bottom end. Electrodes heated by the laser radiation cause the gas to be ionized, forming a plasma-arc in the constricting nozzle. The laser beam passing through the nozzle comes to a focus and interacts with the plasma-arc formed between the electrodes and a workpiece. The resulting interaction between the plasma-arc and the laser beam form a plasma-laser discharge which increases the energy density of the welding spot formed on the workpiece.
Patent CA-2380137-A1 (CA)
Inventor: HENRIKSEN STEN K
IPC: C23F13/04
Filed: 2000-07-21
Abstract: The invention provides a method of inhibiting or preventing corrosion of reinforced steel in concrete by eliminating the differences in surface potentials that result in the total passivation of corrosion activity and create an environment in the steel that does not allow corrosion. The method, optionally includes measuring the active non-uniform surface potential in the steel and passing a DC voltage through the concrete and steel to stop corrosion providing a substantially uniform surface potential on the reinforced steel. The current is controlled and adjusted to send pre-determined amounts of electrical energy to individual areas targeted for treatment. A corrosion potential survey may be conducted to determine the energy requirements necessary for the corrosion condition or a reference electrode may be strategically placed on the concrete structure. The amount of energy passed is sufficient to polarize the reinforcing steel sufficiently to stop corrosion and establish substantially uniform surface potentials on all the reinforcing steel. The invention also includes changing conditions on the surface of steel from a condition of non-uniform surface potential to a condition of substantially uniform surface potential.

Abstract: Methods for making a loaded catheter assembly for delivering a sel-expanding  stent where the self-expanding stent is carried in a compressed state and th e compressed stent has an inside diameter smaller than the outside diameter of  the catheter distal tip. The methods can utilize catheter sub-assemblies lacking already attached tips or having partially formed distal tips. A sten t can be proximally and co-axially slid over the distal end of the catheter shaft and constrained by a retractable sheath disposed co-axially about the compressed stent. The catheter distal tip can be added or more fully formed after the loading of the stent. Some catheters include a preformed distal conical tip held in position by a heat-shrink film. Other catheters have an elastomeric distal tip waist for slipping over and engaging an outward projection on the catheter shaft distal region. Some catheters are adapted t o engage catheter shaft distal threaded regions.

Title: Method and device for producing composite nonwovens by means of hydrodynamic needling
Inventor: ORLANDI VITTORIO
IPC: D04H1/492
Filed: 2001-01-13
Abstract: A known method exists for producing a composite nonwoven from at least one carded nonwoven and a wood pulp layer placed on said carded nonwoven, for producing a hygiene product.  According to this method, the carded nonwoven is hydrody--namically needled before the pulp layer is applied in order to increase the resistance of the nonwoven. However this means that the nonwoven is wet when the pulp layer is applied. The moisture is disadvantageous for the circulation and therefore, the distribution of the pulp. The carded nonwoven still has to be consolidated in order to achieve sufficient resistance to wear by friction. According to the invention, this problem is solved by subjecting the carded nonwoven to action by air or calendering the carded nonwoven before it is coated with the super-absorbent material in order to pre-consolidate said carded nonwoven. The wood pulp layer is applied and the two are then consolidated together by hydrodynamic water needling and dried. This may be followed by additional calendering.

Title: System for implanting a replacement valve
Inventor: TOWER ALLEN J
IPC: A61F2/24
Filed: 2003-04-22
Abstract: A system for percutaneously inserting a prosthesis containing a biological replacement for a defective valve into an implantation site through a body lumen. The system contains a balloon catheter upon which a collapsable stent containing a venous valvular replacement is mounted. A protective shield is slidably mounted upon the catheter that is movable between a closed position over the balloon and an open position wherein the balloon can be inflated to expand the stent. A central lumen runs through the catheter that is formed of stainless steel. The central lumen provides a one to one torque ratio between the proximal end of the catheter and the distal end to enhance the steerability of the catheter. The vein of the replacement is reduced in thickness between 50% and 90% of its original size thereby considerably reducing the size of the replacement package when the stern is collapsed upon the balloon of the catheter.
