Patents Press-fit pipe joint for motor vehicles Applicant: Henn GmbH, Austria This invention relates to a method for creating a press-fit pipe joint with a plug-type connection for connecting pipes and tubes to fixed connecting points in motor vehicles. The pipe (13) is connected to and sealed in a plug-in opening (12) of a connecting sleeve (7). The pipe that is to be press-fitted is introduced to the plug-in opening that has some radial play. An expanding mandrel is inserted into the pipe, and deforms it outwards towards the internal guiding part of the connecting sleeve (17). This guiding sleeve is then deformed radially outwards with the pipe. Patent number: WO 2005/046906

Energized restraining gasket for mechanical joints of pipes Applicant: United States Pipe & Foundry Company, USA This patent is concerned with pipe joints for water pipelines etc. that may be subjected to additional stress due to ground movement. The purpose is to provide a gasket that is interchangeable with gaskets of standard mechanical joints, but which allows for the transformation of the joint into a restrained joint without the need for any reconfiguration or adaptation of the bell, spigot or gland of the mechanical

joint involved. It may also provide a dynamic connection for pipes that does not require high insertion pressures. The seal contains a locking segment that will grip the pipe when the connection is tightened, to provide a restraint against pullout forces and other movement. A number of potential configurations are covered, as well as seals without the restraint element. Patent number: WO 2005/047745 Inventor: D. Copeland Publication date: 26 May 2005

The press-fit pipe joint assembly for automotive applications that is described in WO 2005/ 046906.

Improved holding gasket Applicant: Tame Industrial Navarcles sl, Spain The invention relates to what is called a holding gasket. It is in the form of an assembly in stainless steel that in outline resembles a bellows. It is equipped with connection means which are provided at the ends (5) of the convolutions and peripheral rectangular openings (10), which are arranged parallel to one another. Patent number: WO 2005/047749 Inventor: D. Fernández Publication date: 26 May 2005

Example of the pipe joint with a restraint insert in the seal, prior to tightening of the connection, from WO 2005/047745.

Low-formaldehyde thermoplastic seal adhesive The stainless steel holding gasket as described in WO 2005/047749.

Lip seal assembly Applicant: Federal-Mogul Sealing Systems Bretten GmbH, Germany This invention relates to the static sealing and assembly of a rotary shaft lip seal. The seal sits in a housing area (4) and has a dynamic lip (7). The static sealing area (5) is at least partially laminated with a hardenable material containing a predetermined number of friction-reducing elements (9, 11). Patent number: WO 2005/047740 Inventors: F. Warnecke and X. Jin Publication date: 26 May 2005 12

Applicant: Lord Corporation, USA This patent discloses aqueous adhesive compositions which emit low residual formaldehyde, and which are suitable for bonding rubbers to a metal substrate under pre-bake conditions. The adhesive composition comprises a phenolic novolik, acid acceptor and chlorinated natural rubber,

without an organic crosslinker. The adhesive can also include precipitated silica and/or carbon black. The patent also includes composite components of rubber bonded to metal, such as seals, gaskets and linings. Patent number: WO 2005/047413 Inventor: B. Carney Publication date: 26 May 2005

Integral seal for centrifuge chamber

The lip seal assembly described in WO 2005/047740, which is designed to have frictionreducing elements on the static sealing surface.

Applicant: Zymequest Inc, USA This patent is designed to overcome a problem with centrifuge bags, particularly those used for centrifuging blood. This is joining the bag with the centrifuge hub for an airtight and sterile seal. While such seals have been accomplished in the past, such methods have been costly

and time-consuming, requiring separate gasket materials to be placed between the two items being joined. This invention provides a novel hub-chamber/bag assembly. Patent number: WO 005/051548 Inventors: K. Rosiello, W.G. de Quevedo and K.D. Boudreau Publication date: 9 June 2005
