Patent number: 6416904Abstract: An improved design and manufacturing method is disclosed for calendered, double side segment coated webs. By staggering the leading edges and/or the trailing edges of the segment coatings on one side of the web from those on the other side, web damage, including the incidence of breakage, can be reduced. Further, vibration and wear on the calendering apparatus can be reduced. The invention is particularly useful for heavily calendered webs such as the electrodes in non-aqueous rechargeable lithium ion batteries.Type: GrantFiled: October 23, 2000Date of Patent: July 9, 2002Assignee: E-One Moli Energy (Canada) LimitedInventors: Jan Naess Reimers, Akiyoshi Manabe, Alexander Man-Chung Leung

Publication number: 20020083704Abstract: A pneumatic oil pump has a cylinder, a piston, a pedal and an oil reservoir. The cylinder has a central bore, a sealed front end and a sealed rear end. An air connector is mounted in a cover on the front end of the cylinder. An actuating valve is mounted in the cover on the front end of the cylinder and communicating with the air connector and the central bore of the cylinder. The piston is movably mounted in the bore of the cylinder to divide the central bore of the cylinder into a first chamber and a second chamber. A piston seat is attached to the piston at an end facing the rear end of the cylinder. A ventilative, sound-absorbing material is arranged between the air outlets of the piston and the piston seat. By such an arrangement, the shock of the air flow can be absorbed by the ventilative, sound absorbing material. Therefore, noise and shock will not occur when the pneumatic pump is in operation.Type: ApplicationFiled: January 4, 2001Publication date: July 4, 2002Applicant: Tai E International Patent and Law OfficeInventor: Ta-Chin Wang

Patent number: 6413588Abstract: The present invention relates to a process for producing a durable multi-layered coating on difficult-to-coat substrates, such as aluminum. The process includes subjecting the surface of the difficult-to-coat substrate to a adhesion promoting step, followed by applying an intermediate layer of flexible primer, which contains a polyester copolymer produced through a two-stage polymerization process. A mar resistant top layer of clear coating composition is then applied over the intermediate layer to produce the multi-layered durable coating on the difficult-to-coat substrate. If desired, the intermediate layer may be pigmented or it may be applied in the form of one or more patterned layers of different colors. Alternatively, one or more patterned layers of different colors may be applied over the intermediate layer before the application of the mar resistant top layer.Type: GrantFiled: November 1, 1999Date of Patent: July 2, 2002Assignee: E.
