Abstract: The present disclosure relates to energy storage devices having: a sealed container configured to house a plurality of energy storage devices and enable electrical communication via terminals of the sealed container and a vent located on a periphery of the sealed container. The vent generally comprises a vent panel; a countersink located adjacent the vent panel; at least one score located in the countersink; a buckling initiator at least partially located on the countersink, where the buckling initiator is configured to intersect with the at least one score; and a hinge portion attached to the vent panel, where the hinge portion is positioned opposite the buckling initiator.

Abstract: The present application provides for various embodiments of energy storage devices and various methods of utilizing the same.

Abstract: A spool has a spirally-wound, elongated channel having a C-shaped cross-section with a pair of arms extending from a central web. The channel is oriented with the pair of arms parallel to the axis of the spool and with the central web extending radially, relative to the axis of the spool. The channel has a plurality of adjacent windings, a first and second of the arms of spirally-wound channel cumulatively forming the inner and outer surfaces of the spool. The arms are spaced apart a distance approximating the width of the central web, such that the central web of the windings of the channel is received between the arms of adjacent windings and is retained therein to establish an overlap of windings in the axial direction. Other embodiments feature S, B and E-shaped channels to form the spool, some embodiments having inner and outer layers of channel.

Abstract: The invention relates to a structural sheet formed with cup-shaped projections in which the sidewalls are formed by a sigmoidal line of revolution to provide for more uniform distribution of stress in the structural sheet. There is also provided a novel two-component structural panel which incorporates the advantages of such a structural element to eliminate depressions in the outer panel member which would present "read through" problems.

Abstract: A scissor jack having four aluminum arms of U-shaped cross section which are substantially identical and which may include a hollow aluminum lead screw. The threaded nut through which the lead screw is mounted may be made of glass fiber reinforced plastic as may the saddle which is adapted to engage the undercarriage of a vehicle.
