Interference-seal plunger for an artificial lift system
PATENTS Constant velocity joint having a non-rotating boot Applicant: GKN Driveline North America, Inc. USA A direct torque flow (DTF) constant velocity joint (CVJ) arrangement is described in which the boot remains stationary. A DTF joint may have the outer race of the CVJ friction welded to the output shaft and the inner race have a female spline that is connected to the transmission.
The accommodation of a traditional boot can involve addition space and clearances, reducing the performance of the joint and increasing the space required. The non-rotating boot is statically attached to the transmission housing (96) and has a dynamic rotating seal on the output race, (98). This arrangement is also claimed to make it easier to inspect the joint Patent number: WO/2007/076353 Inventor: H.Wormsbaecher Publication date: 5 July 2007
Seal for a connector and the connector Applicant: FCI, France This applicant is a manufacturer of electrical connectors for a wide range of applications including the automotive industry. The patent describes a boot type seal that has a sealed aperture. A connector can be inserted through the seal and the boot will provide protection for the connection. Patent number: WO/2007/076887 Inventor: A. Flers Publication date: 12 July 2007
This constant velocity joint has a non-rotating bellows and a dynamic seal operating on the outer diameter of the ouput race.
Piston ring, method for manufacturing and coating Applicant: Federal-Mogul Burscheid GmbH, Germany This patent describes a piston ring that has a run-in surface layer described as carbon comprising hydrogen and nanocrystalline carbide phases. This is applied by means of a PVD process. The coating is applied to the running surface and the upper side of the piston ring. Patent number: WO/2007/079834 Inventors: S.Hoppe et al. Publication date: 19 July 2007
Rotary valve internal combustion engine with seal and valve register Applicants/Inventors: V. Consoloni and K. Valentinitsch, Italy An internal combustion engine with combustion chamber inside the rotary valve is described. Elastic seal rings are fitted around the valve to seal it in the head. Further grooves for straight seals are made in the head around the apertures of the induction and exhaust pipes. Patent number: WO/2007/080619 Publication date: 19 July 2007 14
Sealing Technology
Rotatable drill seal Applicant: Robert Bosch GmbH, Germany This invention describes a dust collector that can be fitted to a percussion or hammer drill. A drill bit can be guided through the seal. Patent number: WO/2007/080025 Inventors: O. Baumann and H. Schmid Publication date: 19 July 2007
Vehicle gasket for integrated transport refrigeration unit Applicant: Carrier Corp. USA This patent describes a gasket that can be used when a refrigeration unit is mounted on the top of a vehicle. The vehicle roof has an opening that receives the refrigeration unit. The gasket provides a seal between the refrigeration unit and the vehicle roof. The gasket covers the exterior layer and the interior layer and is formed from multiple layers of material which are secured to one another. Patent number: WO/2007/081338 Inventors: B. Chakiachvili and G. Donnat Publication date: 19 July 2007
The action of the connector seal described in WO 2007/076887.
Interference-seal plunger for an artificial lift system Applicant/Inventor: D.M.Casey, USA This patent is designed to improve the sealing of an artificial lift plunger that is used in a depleted oil and gas well. It is passed down the well, where it seals and allows gas pressure to build up sufficiently to push the plunger to the surface. Patentable feature in this design is a flexible seal between the plunger and the well bore. Patent number: WO/2007/082109 Publication date: 19 July 2007 Editor’s comment: Bicycle tyre pump technology has now reached the oil industry.
