Title: Improved eccentric drive shaft for atherectomy device and method for manufacture
Inventor: SPASSKY MIKHAIL
IPC: A61B17/32
Filed: 1999-03-17
Abstract: This invention is a method of manufacturing a rotational atherectomy drive shaft (20) having an asymmetrical tissue removal section (28). One or more strands of wire are helically wound about an elongated mandrel having an enlarged diameter section (28) with a predetermined shape, thereby forming an elongated, flexible drive shaft (20) which has an enlarged diameter tissue removal section (28).  A protion of the drive shaft (20), including the enlarged diameter tissue removal section (28) is placed into a first clamp, and given a first heat treatment to give the wire turns (31) of the enlarged diameter tissue removal section an initial set, thereby preserving the initial shape of the enlarged diameter tissue removal section (28) of the drive shaft (20).  The drive shaft (20) is then removed from the first clamp, and the mandrel (50) is dissolved. The enlarged diameter section (28) of the drive shaft (20) is then deformed to an asymmetrical shape by placing a portion of the drive shaft (20), including the enlarged diameter tissue removal section (28) into a second clamp. The clamped portion of the drive shaft (20) is then heat treated for a second time to give wire turns (31) of the enlarged diameter tissue removal section (28) a new set, thereby preserving the asymmetrical shape of the enlarged diameter section (28). In its asymmetrical shape the enlarged diameter tissue removal section (28) has a longitudinally flat "side", i.e., all wire turns of the tissue removal section may be connected by an imaginary straight line which throughout its length is parallel to the rotational axis of the driveshaft.
Patent CA-2339804-A1 (CA)
Inventor: BRUSKI RICHARD S
IPC: B22D47/00
Filed: 1999-08-06
Abstract: Il est possible de faire fondre rapidement un matériau composite granulaire (20) préhumidifié en plaçant les granulés dans un four (34) à induction qui fait fondre la matrice métallique des granulés et produit un mélange en fusion. En appliquant une forte puissance à la bobine d'induction, on amène rapidement les granulés à leur point de fusion, et à des températures supérieures permettant de mouler le mélange en fusion. La rapidité d'échauffement permet de préparer par mélange dans l'air des matériaux composites qui seraient sinon réactifs.

Title: Centrifugal filter for removing soot from engine oil
Inventor: MAY DAVID F
IPC: B04B9/08
Filed: 2001-04-25
Abstract: A centrifuge filter for removing soot from engine oil. The centrifuge filter includes a rotor adapted to be rotated inside a centrifuge housing by an electric motor or other means. The rotor preferably includes a reusable aluminum support casing and a disposable plastic cartridge. The plastic cartridge includes a trap with partition walls to prevent wave formation in the rotating liquid contained in the trap. The cartridge includes an annular inlet through its top end, a winding flow path through the cartridge and an outlet at the bottom enc. The centrifuge housing includes an isolated sealed rotor chamber. Using the venturi effect, air is evacuated from the rotor chamber to provide a partial vacuum to reduce air drag on the rotor. Resilient rubber vibration isolators are used to reduce vibrations and engine induced shock loads from reaching the rotating element. A side oil inlet is provided in the cartridge to receive unfiltered oil at a location offset from the axis of rotation. Oil is feed in through the top of the centrifuge cartridge and discharged out the bottom. The rotor is carried by bearings on a stationary central support shaft. Maintenance is performed through a removable lid on the top end of the rotor. A restriction plug is used to control flow into the rotor.

Abstract: An alpha-numeric string electronic telephone and client service provider communication system is superimposed over the existing Internet, telephone, and pager legacy systems to provide a much simpler communication system that  will work seamlessly with the existing communication systems. The new system  will allow an unlimited number of connections and an unlimited numbers of signal type protocols to be used in the future and eventually phase out all of the separate numeric only telephone systems world wide and at the same time integrate the legacy e-mail system of the Internet with the legacy world wid e numeric communication systems in a seamless and more powerful manner. Some other advantages of the new system is to eliminate the need for having to li st up to five or more numbers on an individual business card. The system can eliminate the need to show multiple area codes at the same location and can even eliminate the need to have to give out ones company extension number. Another major benefit is that at least two types of communication connection s can be offered at different prices to the customer. With the current inventi on a client service provider can offer connections of the legacy direct type at  one price and connection via the Internet at a different price depending on the servicerequested by the customer.
