The tube-guiding sleeve is used for mounting a roll-back tube drive.Type: GrantFiled: June 11, 1998Date of Patent: September 11, 2001Assignee: STM Medizintechnik Starnberg GmbHInventors: Robert Pauker, Thomas Viebach, Fritz Pauker, Gerhard Weiglhofer

Patent number: 6250339Abstract: There is provided a sound-absorbing and a heat-insulating duct comprising a nonwoven cloth layer 1, a reinforcing core 2, a foam strip layer 3, a bonding resin 4 and resin-coating layer 5. The nonwoven cloth layer 1 is formed by wound spirally a nonwoven cloth 10 into a tube-like shape in which adjacent side edges of the adjacent nonwoven cloths 10 are brought in abutment against or lapped with each other so as to form a bonding portion 1a. The reinforcing core 2 made of hard synthetic resin material is wound spirally on the bonding portion 1a while a surface of the reinforcing core 2 being brought into contact with the nonwoven cloth 10 is welded or bonded to the nonwoven cloth 10. The foam strip layer 3 is formed by wound spirally a foam resin strip 30 having a width approximately equal to a width of the nonwoven cloth 10. Both adjacent edges 3a, 3b of the foam resin strip are disposed on adjacent reinforcing cores 2, 2 respectively.Type: GrantFiled: January 28, 2000Date of Patent: June 26, 2001Assignee: Totaku Industries, Inc.Inventors: Hiroshi Ikegami, Susumu Okairi

Patent number: 6244303Abstract: A flexible hose 10 having a flexible material 12 and a more rigid material 14. The flexible material 12 and the more rigid material 14 being helically wound and molded together to form a hose 10 with an exterior surface 16 and an interior surface 18. The cross-section of the more rigid material 14 having at least two peninsulas 20, extending in longitudinally opposite directions, at least one radially inwardly extending peninsula 22, and at least one radially outwardly extending peninsula 22. The longitudinally extending peninsulas 20 are embedded in the flexible material 12 and the radially extending peninsulas 22, 24 are at least partially embedded in the flexible material 12. In the preferred embodiment, the longitudinally extending peninsulas 20 are centrally located in the flexible material 12 between the respective surfaces 16, 18 of the hose 10 and the radially outwardly extending peninsula 24 extends beyond the flexible material 12 on the exterior surface 16 of the hose 10.Type: GrantFiled: January 21, 2000Date of Patent: June 12, 2001Assignee: The Goodyear Tire & Rubber CompanyInventor: Anthony Dennis Adams

Patent number: 6240160Abstract: A system for inspecting pipelines, especially in the coupling between pipe parts, comprises a radiation source and a detector device or a photographic film. The pipeline includes indicators which are laid into the pipeline material and have a differing absorption of radiation than the material comprising the layers of the pipeline in which the indicators are formed. By placing the radiation source and the detector device (or photographic film) on opposite sides of the pipeline, or on opposite sides of a wall of the pipeline, the position of the indicators may be detected, and any displacement can be measured.Type: GrantFiled: June 14, 1999Date of Patent: May 29, 2001Assignee: Den Norske Stats Oljeselskap A.S.Inventors: Alf Daaland, Svein Åge Holen
