Patent CA-2347623-C (CA)
Inventor: HAUSBICHLER HANNES
IPC: B29B7/76
Filed: 1999-10-19
Granted: 2008-07-22
Abstract: The invention relates to a valve device (14) for low-viscosity to high-viscosity fluids, especially for fluid plastic material constituents (12) of single or multiple constituent plastic mixtures. The inventive valve device comprises a valve housing (18) with a fluid inflow (20, 30) and a dosing valve (15) which has a dosing nozzle (22) that can be optionally closed or opened by a closing element (23). Said valve device also comprises a pressure control device (40, 44) which influences the fluid in the fluid inflow. In order to maintain a constant fluid pressure in the housing which is not influenced by the position of the closing element, the invention provides that the pressure control device is essentially comprised of a control membrane (40) which can be pneumatically prestressed and which acts upon the closing element (23). The invention enables a particularly easy isobaric control or regulation of the fluid inflow since the fluid pressure on one side of the membrane and acting upon the same is in equilibrium with the air pressure prevailing on the other side, and since the air pressure and thus the control membrane remain practically unchanged due to the compressibility of the gas when the closing element is displaced.

Abstract: A cryogenic fluid distributor for turret machine tools (e.g.,lathes) directs a stream of cryogenic fluid from an external, pressurized cryogen source to a working position of a machine tool to prevent overheating of the tool. Designed for easy retrofitting and synchronizing with multi-tool turret machines, the distributor allows for a "dual-fluid" machining capability combining a cryogenic fluid and a conventional cutting fluid (flowing via a conventional coolant system built into a given machine tool). Made of low thermal-mass, insulating polymer and metallic parts, the distributor utilizes the different thermal contraction coefficients of the parts to establish cryogenic sealing connections, which eliminates undesired turret plate cooling and assures rapid cryogen flow start-up.

Abstract: La présente invention concerne un rotor (1) qui est parcouru par un fluide dans une direction d'écoulement principal (H) et qui est doté d'au moins une pale (4) tournant autour d'un axe de rotor. La pale (4) s'étend au moins par sections de l'axe de rotation (2) vers le fluide. La rotation (D) de la pale (4) autour de l'axe de rotation (2) dans un sens de rotation prédéterminé engendre une force propulsive dirigée à l'encontre de la direction d'écoulement principal, notamment l'écoulement entraîne un moment de couple autour de l'axe de rotation. Pour obtenir avec de tels rotors une réduction des tourbillons en bout de pale et donc une réduction des pertes en termes de mécanique des fluides et des bruits d'écoulement, la pale (4) se prolonge à une certaine distance de l'axe de rotation par au moins deux pales partielles (5, 6) et forme une boucle. Une pale partielle (5) s'étend au moins dans une zone proche de la pale dans le sens de rotation (D) par rapport à la pale (4) et l'autre pale partielle  s'étend au moins dans une zone proche de la pale (4) à l'encontre du sens de rotation (D) par rapport à la pale (4). A leurs extrémités, les deux pales partielles (5, 6) sont reliées d'une seule pièce de telle façon qu'elles entourent une surface boucle (12) qui est parcourue par le fluide et qui s'étend sensiblement perpendiculairement au sens d'écoulement principal.

Abstract: The invention comprises a section of improved tubing with coupled end connectors and an insert containing at least one electrical wire. The insert has an outside diameter that is approximately equal to the inside diameter of the improved tubing. The insert also has projections at each end such that when two inserts are placed end to end, the projections will mate up. The insert has at least one groove cut into its side and running the length of the insert. The groove is for the placement of a wire for transmission of power to the well bore or for the placement of a wire for transmission of data from the well bore. The groove is installed down the length of the insert. The groove is deep enough so that when a wire is placed inside the groove, the wire does not project beyond the outside diameter of the insert. The insert may contain as many groove and wire combinations as are necessary for the particular application. The wire has an electrical connection at each end of the insert. When the inserts are placed end to end, the insert projections line up the electrical connectors and correct mating of the insert projections will result in correct mating of the electrical connectors. The inserts are the same length as the tubing and are installed inside the tubing such that the insert is flush with the first end of the tubing. The inserts are then welded to the tubing or secured to the tubing by some other method. A threaded coupler is then installed on the second end of the tubing to protect the exposed insert and electrical connector. The coupler will also be used to secure the improved tubing together. Individual pieces of improved tubing are connected together in a three step process. First the coupler is threaded onto the second end of the tubing. Next, the first end of one tubing member is positioned above the second end of another tubing member. Next, the insert projections are properly aligned so that they will mate together. Then, the two pieces of tubing are plugged together so that the electrical connections engage each other. Finally, the coupler is screwed onto the first end of the tubing so that the two pieces of tubing are secured together. The process may be repeated as necessary to create an elongated string of improved tubing.
