Abstract: L'invention porte sur une pompe à sang (10) à écoulement axial comportant un rotor (20) suspendu dans des paliers à bille et à rotule (38, 34) qui sont refroidis par le sang, mais non lubrifiés activement par le sang. Les structures à bille et à rotule sont fabriquées dans un matériau hautement thermoconducteur et sont en contact par transfert thermique avec des pales (30) de stator thermoconductrices qui servent de puits thermiques pour les paliers. Les structures à bille et à rotule sont radialement plus petites que les pales du stator. L'interface bille-rotule comporte un très léger vide qui fait que les structures à bille et à rotule présentent une surface essentiellement continue adaptée à l'écoulement sanguin.

Title: Method and apparatus for manufacturing products through the use of waste materials of various kind, and product obtained therewith
Inventor: BERTOGLIO MARIO
IPC: B29C45/16
Filed: 1999-04-08
Granted: 2001-12-04
Abstract: A method and an apparatus for manufacturing products through the recycling of waste materials and whereby the optional addition of raw materials may occur. The waste materials and optionally used raw materials are first shredded into small-sized particles, preferably from 1 to 10 mm in size, and then mixed together to form a first blend that constitutes a first component of each product, which is adapted to form the inner, non-visible portion, or core, of each product, and a second blend which constitutes a second component of each product, and which is adapted to coat the inner portion and form the outer visible portion, i.e. skin, of each product. The first and said second blends are subsequently heated separately from each other, following addition to the first blend of heat stabilizing means and blowing means adapted to cause the first blend to swell or foam during heating, as well as the addition of colouring means to said second blend. Heating takes place to a temperature of approx. 180 to 210°C, thereby achieving first and second plasticized masses. Constituents having higher melting temperatures than said pre-determined heating temperature are incorporated in the masses where they behave like inert filling materials. The first and said second plasticized mass are then injected simultaneously into a moulding means reproducing the shape of the respective products, thereby homogeneously mixing with each other so that the lower density, higher fluidity compound forms the outer portion and the higher density, lower fluidity compound forms the inner portion of the product.

Abstract: The generator of an engine-driven welding machine is comprised of front and rear housings that attach directly to each other. The generator stator may be secured solely to one or the other housing with preloaded screws. Alternately, one or more preload elements may be interposed between the stator and one of the front or rear generator housings. Thermal stresses are thereby avoided between the stator and the generator housings, despite the housings being made of aluminum and the stator being made of steel. The rear generator housing has an end wall that is mountable to different selected internal combustion engines by means of teardrop shaped clearance holes and machineable bosses.      Slots for cooling air in the rear generator housing have sides with tangential components. Air leaves a fan in the generator with tangential components that are matched by the rear generator housing slots. The fan incorporates both fan blades and a baffle having a close clearance with an annular wall of the rear generator housing. Side ducts in the rear generator housing allow cooling air to flow around the front generator housing and into the rear generator housing before being expelled out the rear generator housing slots.

Granted: 2007-11-13
Abstract: A method and apparatus is provided for gathering computer network data, such as Internet data, in accordance with a subscriber's preferences, and transmitting the computer network data to a terminal along with various other channels of video programming. After collecting the data, it is multiplexed together with video data, representing video programming, to form a multiplexed signal for transmission over a network to a terminal. Based on a unique terminal ID of each terminal, the network selectively routes the computer network data portion of the multiplexed signal that is specific to each terminal to the respective terminals.

Title: Protective device for injection or aspiration needle
Inventor: ASBAGHI HOOMAN A
IPC: A61M5/46
Filed: 2000-06-15
Granted: 2009-01-06
Abstract: A protective device for injection or aspiration needles has a barrel piece telescopically slidable over an adapter sleeve mounted at one end to the luer coupling of the syringe or to a multisample collector. An injection needle is mounted within the adapter sleeve, projecting out through an opening in the opposite nose end of the barrel piece. An interposed spring urges the adapter sleeve and barrel piece apart towards a fully extended position. The barrel piece and adapter sleeve are latched together in a ready to use position with the needle partially protruding out from the barrel piece. As the syringe or multisampling system is advanced, the needle is extended out through the barrel piece end to allow penetration into the patient's body, and automatic unlatching is induced as penetration begins. As the needle is withdrawn from the patient, the spring causes the needle to be fully withdrawn within the barrel, and locking features engage preventing any axial movement to insure permanent enclosing of the needle within the barrel piece and defeating any attempted reuse of the needle. A reference scale on the barrel piece aids in determining when the proper depth of penetration has been achieved.
