Sealing film Applicant: Surgichem Ltd, UK This patent describes the sealing film for the covering film of a pill dispensing tray.
Seal for bearing assembly Patent number: WO 2006/013371 Inventors: S. Valentine, J. Hart and M. Chadwick Publication date: 9 February 2006
Seal with plastic inner cup Applicant: SKF USA Inc, USA This patent describes a composite unitized seal for heavy truck and trailer hub seals. The inner supporting cup of the seal assembly is manufactured from a plastic molding instead of the usual steel pressing. The potential benefits of the plastic include; reduced weight, noise reduction, convenient molding in of part numbers and reduced cost. The plastic will also introduce improved design flexibility to introduce facilities such as magnets and heat sensors. A number of ribs (78) are molded into the plastic for strength. Patent number: WO 2006/017038 Inventors: D. Denton, L.
Applicant: Gunite Corporation, USA This patent describes a seal that is used as a static seal between the inner cone and the hub of a wheel bearing assembly [I think – Editor]. The benefit appears to be that the pair of
taper roller bearings can be more readily stored, handled and assembled as a pair. Patent number: WO 2006/015289 Inventors: R.A. Pete and O.J. Fakhoury Publication date: 9 February 2006
Liquid handling device with surface features at seal
The truck hub bearing seal on which the inner supporting cup is manufactured from plastic, from WO 2006/017038.
Applicant: Protedyne Corporation, USA This invention relates to plunger operated sample handling tools such as automatic pipetting devices which have a series of plungers in parallel. The plungers are typically sealed using an O-ring or X-ring. It has been found that improved seal life can be achieved if the surface of the plunger includes features such as a groove, pit, protuberance or cavity etc. The patent describes a
plunger with a spiral groove that may be any size up to 1–2 mm in cross-section. Other surface features are also covered including porosity. Patent number: WO 2006/017186 Inventors: P. Massaro and M. Paschetto Publication date: 16 February 2006 Editor’s comment: This is not the 1 April edition of the news. If these are for bio-science research then cleaning the plunger must be interesting.

Introducer assembly with suspended seal Applicant: Tyco Healthcare Group, USA This patent describes a surgical access apparatus that includes a seal. The seal design includes an
outer and inner lip. Patent number: WO 2006/020267 Inventors: D.C. Racenet, R.A. Stearns and G.A. Stellon Publication date: 23 February 2006
Head gasket for internal combustion engines Applicant/Inventor: R. Hunter (USA) This patent describes metal cylinder head gaskets that can be manufactured from malleable copper to provide good thermal conduction between the head and cylinder block.
The gasket includes a wire insert surrounding the cylinder bores to provide high-pressure sealing. A number of different designs to accommodate the wire are included. Patent number: WO 2006/020865 Publication date: 23 February 2006
Threaded joint for steel pipes Applicant: Sumitomo Metal Industries Ltd, Japan This patent is a further design of threaded joint for high performance down-hole oil pipe. The thread is designed with a flat flank on the loaded side of the thread and a rounded design on the upper side 14
of the thread. There is also some radial clearance between the male and female thread portions when initially joined to facilitate easier assembly of the joint. Patent number: WO 2006/022418 Inventors: M. Sugino et al. Publication date: 2 March 2066
Examples of surface features that may be used on the plunger of a dispensing pipette to improve the seal life, from WO 2006/017186.
Gas evacuation seal for caps Applicant: Manufacture Generale de Joints, France The invention relates to a gas evacuation seal to be positioned in the bottom of a bottle cap. The application is for fruit juices and other products that may produce some gas. The seal will allow the gas to escape but retain
the liquid contents. The seal has a flat support and a through-hole. Both faces of the seal are covered with a film that is permeable to gases but impermeable to liquids. Patent number: WO 2006/018556 Inventor: J. Delorme Publication date: 23 February 2006
