Gasket for hygienic tube fitting connections
PATENTS Thermoplastic elastomer and gasket for a drum washing-machine
A ‘no-twist’ rod seal for use in steel-rolling mills forms the subject of patent WO/2010/035039, which discusses the replacement of the steel energiser ring (30) with one made from plastic.
able for use in harsh chemical and/or physical environments. Traditionally, these seals have an energiser ring made from stainless steel. However, there are disadvantages to such an arrangement. Making the band in the required shape and configuration, within the desired tolerances, can be difficult. In addition, the band can be difficult to fit, and requires skilled fitters and specialist, dedicated tooling. The band described in this patent includes one or more plastics materials. The material from which it is made, includes at least 80% – preferably 90% – of a plastics material by weight. In some arrangements, it is preferred that the band is made mostly of plastics material, for example, only an engineering plastics material. Compared with a band made from stainless steel it offers a number of advantages. For instance, dimensional accuracy can be improved. The band may be formed by moulding or machining – techniques that may give rise to a more uniform shape and/or configuration than is possible for one made from steel. Problems relating to shape, associated with welding steel bands, also can be reduced or avoided, as can those related to fitting such a band. In addition, the cost of manufacturing a large number of the bands is relatively low. Patent number: WO/2010/035039 Inventor: J. Toynbee Publication date: 1 April 2010
Glass seal Applicant: Rehau Ag + Co, Germany This invention relates to a glass seal for attaching a component to a glass pane in a motor vehicle. It is characterised by its mounting profile, which is designed in such a way that a lower force is required to assemble the attached part than to remove it. Patent number: WO/2010/037432 Inventors: A. Schaff, S. Gruber and U. Kaiser Publication date: 8 April 2010
Seal for retaining lubricant in chain links Applicant: AB SKF, Sweden A seal is described that retains the lubricant in chain links. A composite design, with a support ring, maintains the seal in position and correctly positions the sealing lips. Patent number: WO/2010/037544 Inventor: W. Dolata Publication date: 8 April 2010
Applicant: GS Caltex Corp, Korea This invention covers a thermoplastic elastomer produced from: a multifunctional acrylate monomer, which has a molecular weight of 150–2000 g/mol; a propylene-ethylene random copolymer, which has a melt-flow index of 5–50 g/10 min and has an ethylene content of 1–7%; and an ethylene-propylene-nonconjugated diene terpolymer that has a Mooney viscosity of 40–60 ML(1+4)/125°C, and to which oil has been added. A gasket for a drum washing-machine, which is made from this elastomer and has Shore A hardness of 30–60, is also detailed by this patent. Patent number: WO/2010/038931 Inventors: H.-M. Kang, D.-H. Yang, Y.-B. Kim, T.-H. Im and H.-K. Kwon Publication date: 8 April 2010
Compression sensor gasket Applicant: Federal-Mogul Corp, USA A general approach to providing a pressure sensor within a gasket for automotive engines is described. It may be applied to coolant and lubrication systems or cylinder bores. The purpose is to reduce the number of components required during assembly. The sensor has a tip that is configured to sense pressure within the chamber that is to be sealed. The gasket has, what is termed, a metal distance layer, which includes the housing for the pressure sensor. The housing has an outer, annular, tapered surface that is configured to register in radial alignment with the chamfered surface, in order to create an hermetic seal between the pressure sensor assembly and the gasket body.
Gasket for hygienic tube fitting connections Applicant: Parker-Hannifin Corp, USA A specialist gasket for hygienic tube fitting connections is discussed. A feature of the gasket is an inner sealing bead, in addition to the main sealing bead, which mates with the form of the hygienic flange. Patent number: WO/2010/036388 Inventor: R.J. Dubiel Publication date: 1 April 2010
