Patent number: 6162559Abstract: This invention relates to a battery cell housing for valve-regulated, lead-acid batteries. The housing includes a tray base, vertical side walls attached to the base so that the tray base and vertical side walls define a single battery compartment. A top wall is secured to the side walls and has at least one opening. A compression member is positioned in the battery compartment beneath the top wall for movement between the side walls so as to compress a stack of battery cells stacked in a horizontal position in the battery compartment. At least one internally threaded member is included with the top wall and is aligned with at least one opening. At least one compression bolt extends through the top wall opening and contacts the compression member while threadedly engaging at least one internally threaded member.Type: GrantFiled: September 21, 1998Date of Patent: December 19, 2000Assignee: Douglas Battery Manufacturing CompanyInventors: David G. Vutetakis, Christopher R. Cestone, Stanley K. Wilkie

Patent number: 5981103Abstract: An assembly of an electronic device within a sealed chamber of a flexible container. The electronic device, which may be a printed circuit board, has signal terminals connected to elongated insulated signal conductors. These conductors pass through a laminate construction wall of the container for connection to outside conductors. The signal conductors are electrically isolated from an EMI protection layer which forms part of the laminate construction wall. A grounding device connects a ground conductor of the electronic device to the EMI protection layer. The grounding device comprises a ground element having teeth on one side. A screwthread arrangement extends through the container wall and clamps the ground element onto the wall with the teeth cutting into the EMI protection layer to be in electrical contact therewith. The ground conductor is electrically connected to the screwthread arrangement.Type: GrantFiled: December 12, 1997Date of Patent: November 9, 1999Assignee: Northern Telecom LimitedInventors: L. Eugene Batten, Jr., Dennis A. McCulloch, David H. Williams

Patent number: 5707758Abstract: A nonaqueous electrolytic secondary battery is formed by winding a thin-film positive electrode, a thin-film negative electrode, and a thin-film separator. A cap is arranged at the distal end portion of a pole bored through the cap and interposed between a nut and a disk-like portion of the pole through a ceramic washer being in contact with the nut and a ceramic patch being in contact with the disk-like portion. The ceramic washer and the ceramic patch consist of alumina or zirconia. For a bolt for interposing a bus bar or a conductive line to fix the bus bar or the conductive line, a female screw portion formed in the pole is arranged in a space of a spindle.Type: GrantFiled: September 16, 1996Date of Patent: January 13, 1998Assignee: Nissan Motor Co., Ltd.Inventors: Satoshi Iwatsu, Tatsuo Shimizu, Hideya Takahashi, Yosuke Kita, Kiyoshi Katayama, Etsuo Ogami
