Bipolar battery and gasket
PATENTS
High speed contact developing with end seal Applicant: Lexmark International Inc, USA This patent relates to a photocopying machine in which the developer roller and photoconductor roller rotate at high speed and the developer roller has an end seal subject to frictional heating. The developer roller rotates past a doctor blade, which may also have an electrical charge, and then contacts the rotating photoconductor roller. In this configuration a source of toner is located on the side of the developer roller opposite the photoconductor roller. Seals of various kinds are employed to prevent this toner from escaping from the sides of the developer roller. Typically the seal is a member that is shaped to fit the contour of the developer roller and is resilient so that it can be firmly pressed between the end of the developer roller and a frame member. Some such seals take the form of the letter J and are often termed J-seals. The arrangement patented has a developer roller immediately under the seal that is reduced in stiffness. A void area is located on the developer roller between a
supporting shaft of the developer roller and an outer part of the developer roller. Since that outer part will flex inward somewhat during use, friction between the developer roller and the seal is reduced. In a typical example the difference in temperature between a developer roller of standard configuration and a developer roller having a gap under the seal was 13.5%. Patent number: WO 2005/047984 Inventors: M.D. Foster and J.C. Piotrowski Publication date: 26 May 2005
Example of the J-seal arrangement for a high-speed photocopier machine, which provides lower friction than the previous arrangements, from WO 2005/047984.
Bipolar battery and gasket Applicant: Nilar International AB, Sweden This invention provides a battery that can store more energy than conventional designs, and also provides additional cost and assembly benefits. The gasket acts a hydrophobic barrier and a pressure-tight seal, and also provides a means to create a common gas space within the battery. This in turn makes it possible to use the available space more efficiently, and use larger electrodes. The gasket is made from a hydrophobic material in the shape
of a frame to prevent the creation of an electrolyte path between adjacent cells when fitted in a battery. The frame is designed to partially encompass a biplate when mounted in the battery, and includes a means to permit gas passage through the gasket. The gasket is made from a material with deformable properties to provide a seal between the biplate and endplate. Patent number: WO 2005/048390 Inventors: D. Hock, N. Puester and L. Fredriksson Publication date: 26 May 2005
Cross-section of the battery and gasket arrangement described in WO 2005/048390, which is designed to increase battery capacity and reduce assembly costs.
Bearing with IC tag and seal (1) Applicant: NTN Corporation, Japan This patent covers a bearing with an IC tag (9), which is capable of preventing obstruction such as radio wave reflection and absorption caused by raceway rings etc. The IC tag uses the metal casing of the bearing seal as an antenna so that tag can be reduced in size and increased in capacity. Patent number: WO 2005/052397 Inventors: M. Seriu and S. Takada Publication date: 9 June 2005
Seal for parts with limited mobility Applicant: Weidmann Plastics Technology AG, Switzerland This patent is concerned with the sealing of control levers and similar components in the automotive industry. The seal comprises a rubber-elastic body (5) with an opening (6) for a control lever or
joystick. The outside diameter of the seal provides for attachment to a flange. The molding (9) allows the flange (10) to move within the peripheral edge (7). Patent number: WO 2005/052415 Inventor: J. Ott Publication date: 9 June 2005
A bearing fitted with an IC tag which uses the metal casing of the seal as a radio antenna, as described in WO 2005/052397.
The limited mobility seal for joysticks and similar components described in WO 2005/052415.
Bearing with IC tag and seal (2) Applicant: NTN Corporation, Japan This is a further patent that covers the fitting of an IC tag to a bearing. The tag is encapsulated within the rubber molding of the seal, adjacent to the metal casing, to provide protection from the external environment and extremes of temperature. Patent number: WO 2005/052398 Inventors: T. Nakajima and K. Murakami

Publication date: 9 June 2005 Editor’s note: IC tags are a digital medium that use radiofrequency identification (RFID) technology to keep track of items and automatically discriminate between various types of information through a wireless exchange of data. The electronics industry is currently developing lowcost, high-performance, ultra-thin IC tags for a wide range of uses.
Electrically conductive gasket Applicant: Joinset Co Ltd, Korea This patent describes the construction of an electrically conductive gasket. It includes a conductive sheet from a natural pulp base with a soft aluminum foil adhered to one surface. A hot melt layer is formed on the other
surface of the pulp base, and a nonconductive elastic member is overlapped to be continuously encompassed by the conductive sheet. Patent number: WO 2005/053328 Inventor: S.-K. Kim Publication date: 9 June 2005
