Boot for universal joint
PATENTS
Patents
A seal for use with pipe and flange assemblies
for applications such as medical supplies or emergency food. Dry components and liquid can be stored separately in a single container and them mixed at point of use by breaking the seal. Specialist emergency food and drugs can then be administered safely by untrained staff. The frangible seal may be broken by actions such as gripping the container or contra-rotation of two sections of the container. Patent number: WO 2007/055660 Publication date: 18 May 2007
Applicant: Oceaneering International Inc, USA The invention relates to a seal for use with a pipe and flange assembly. The seal is intended to prevent leakage during axial movement of the pipe relative to a flange. A central cylindrical elastomeric component is located between two circular elastomeric end rings. The seal is particularly intended to be more resistant to sour gas than earlier designs. Patent number: WO 2007/053328 Inventors: M.N.A. Shaw and B.A. Wallace. Publication date: 10 May 2007
Acoustic seal for use in kitchen appliance
Boot for universal joint Applicant: NOK Corp, Japan This universal joint bellows is designed to provide improved durability, by providing a lower resistance to large angular deformations. The radially outward facing section at each end of the boot has a thinner section than the remainder of the bellows. Details of the relative thickness and convolution angles are presented. Patent number: WO 2007/049429 Inventor: H. Satoh. Publication date: 3 May 2007
Windscreen seal and assembly method Applicant: Renault s.a.s, France This patent describes an entire windscreen assembly and fitting method for motor vehicles. A feature of this design is that the finished seal includes a connecting lip which is incorporated into the adhesive bead on assembly. Patent number: WO 2007/051942 Inventor: P. Cordier. Publication date: 10 May 2007
A pipe seal assembly that permits axial movement of the main flange assembly of a pipe joint, from WO 2007/053328.
Mechanical seal Applicant: Eagle Industry Co. Ltd, Japan A mechanical seal is described that has a back-up ring on the atmospheric side of the rotating secondary seal O-ring. The back-up ring specifically has a lower permeability than the O-ring. It also has an inside diameter that is larger than the shaft so presumably is precluded from acting as the secondary seal. Patent number: WO 2007/055156 Inventor: N. Nakahara Publication date: 18 May 2007
Process for producing a high temperature ceramic/metal seal Applicant: L’Air Liquide Societe Anonyme pour L’Etude et L’Exploitation des Procedes Georges Claude, France A process for producing a joint between ceramic and metal components is described. The jointing material is a mixture of glass and ceramic powder. The preparation of the powder, pressing of the preform, densifying and heating is described. Patent number: WO 2007/054462 Inventors: N. Richet et al. Publication date: 18 May 2007
October 2007
Applicant: Owens Corning, USA A replacement for the acoustic insulation that is provided on many dishwashers is described. This version functions as both an acoustic insulator and seal and is fitted as a single component reducing labour costs. Patent number: WO 2007/056024 Inventor: A.L. Panther. Publication date: 18 May 2007
Seal arrangement for filter element Applicant: Donaldson Co. Inc, USA This patent is concerned with engine air intake filters, it covers the filter element, seal and methods of assembly and use. Improvements in the filer element pre-form and seal are described. These include: a single beveled surface of the seal to facilitate installation and an inside region of the seal having a tip adjacent to an inwardly directed lip of the pre-form, to control flash during moulding. A variety of media pack configurations and features are described. Patent number: WO 2007/056589 Inventors: B.K. Nelson et al. Publication date: 18 May 2007
Asset seal device and method The low permeability back-up ring fitted to a mechanical seal secondary seal. The relative dimensions of the back-up ring and metal components are specified, from WO 2007/055156.
A container with separately sealed compartments Applicant/Inventor: K.M. Hiew, Singapore This patent describes a container that is specifically designed for use by emergency services and disaster agencies. It can be used
Applicant: Motorola Inc, USA This patent describes a bolt that may be used as part of the system for sealing a container. It is fitted with an RFID tag. When the container is sealed the RFID circuit is connected. If the bolt is loosened or broken the tag will transmit the relevant data. Patent number: WO 2007/056636 Inventors: N.C. Hopman and R.S. Flatt. Publication date: 18 May 2007
