Publication number: 20040239111Abstract: Normally, compressed air coupling plugs lock inside a coupling housing. Decoupling must consequently occur by releasing said plugs counter to the friction forces existing between the plug and the housing. This requires force and the plug may not relieved of pressure when decoupled. The invention works with a locking element (2) which is mounted in a coupling housing (1). The plug (5) and the locking element (2) are provided with reciprocally corresponding locking means (24, 52; 28, 56) whereby the locking element (2) can be pivoted for decoupling without the plug (5) pressing on the housing (1), thereby enabling large caliber tubing, such as those used with construction compressors, to be coupled by hand without tools.Type: ApplicationFiled: February 3, 2004Publication date: December 2, 2004Inventor: Hans Wuthrich

Patent number: 4986575Abstract: In an annularly corrugated flexible plastic protective tube or conduit for receiving lines the longitudinal slit thereof is so widened that it is readily possible to insert the lines without interference. Clamped in fitting manner on the tube is an outer tube which also has a wide longitudinal slot and which covers the longitudinal slot of the first tube. The locking engagement of inner and outer tubes can be improved by corresponding complementary formation of the ribs or corrugations of the tubes. Branch pieces can be clamped onto the inner and outer tubes.Type: GrantFiled: November 17, 1987Date of Patent: January 22, 1991Assignee: Frankische Rohrwerk Gebr. Kirchner GmbH & Co.Inventor: Franz-Josef Braun

Patent number: 4981170Abstract: A heat exchanger for various kinds of liquid and gaseous fluids includes a tubular conduit having a corrugated heat exchanging outer wall and a stationary baffle and turbulator plate mounted inside each corrugation. The turbulator plates divert the fluid flow radially into contact with the large surface areas of the corrugations and a ribbed construction on each turbulence plate adds to the turbulance of the fluid flow to enhance heat exchange. An assembly of tubular conduits is provided with quick disconnect attachments whereby individual conduits may be easily removed and replaced.Type: GrantFiled: November 29, 1989Date of Patent: January 1, 1991Inventor: Robert F. Dierbeck

Patent number: 4897963Abstract: In order to place in sealed communication two reactor containments provided with openings capable of having a displacement between their axes, an assembly (12) is placed between the flanges (B.sub.1, B.sub.2) delimiting these openings, said assembly comprising two mobile linking parts (30a, 30b) according to a common axis, these parts bearing lip seals (36a, 36b) coming to take sealed support on the flanges under the action of a control (52) and springs (44) mechanism. Two double doors (14a, 14b) can be placed inside the openings and the linking parts in order to ensure separation of the containments. These double doors are formed of doors (16a, 18a, 16b, 18b) interconnected by means of magnets (62a, 64a, 62b, 64b) authorizing a certain relative sliding.Type: GrantFiled: October 4, 1988Date of Patent: February 6, 1990Assignees: Commissariat A L'Energie Atomique, EuritechInventors: Michel Reboul, Charles Glachet

Patent number: 4767137Abstract: A tube connecting device is provided that connects rectangular tube ends in a fluid-tight manner with one another. The tube ends communicate with one another at their ends in a tube connecting device. A first tube end has a frame that is open on one side, this frame having a circumferential groove. A second tube end has a circumferential flange that is received in the circumferential groove. This open side of the frame is covered by a sealing strip fastened thereto, this strip clampingly spanning adjacent portions of the frame and flange.Type: GrantFiled: March 18, 1987Date of Patent: August 30, 1988Assignee: MTU MOTOREN-und Turbinen Union Munchen GmbHInventors: Hans Zinner, Hans Kaupp

Patent number: 4767136Abstract: The device for coupling two pipes comprises a variable length assembly formed from two tubular parts, whereof the internal diameter corresponds to the internal diameter of the pipes. The tight coupling of this assembly to the ends of the pipes is brought about by compressing O-rings between a planar surface and a spherical surface by means of two nuts. The two tubular parts are then tightly joined by actuating a nut compressing a third O-ring.Type: GrantFiled: June 18, 1987Date of Patent: August 30, 1988Assignee: Cogema, Compagnie Generale des Matieres NucleairesInventor: Jean Lehmann
