Abstract: An energy storage system is disclosed. The energy storage system includes a first energy storage cell, a second energy storage cell, and a first interconnect connecting the first and second cells. The interconnect includes a support member and a plurality of protrusions extending away from the support member. At least two protrusions are spaced relative to each other along a longitudinal axis of the interconnect.

Abstract: A pipe seal assembly for a poured concrete tank or box in an on-site waste disposal system including a seal member having an inclined inner wiper flange which releasably retains a mandrel, and plug means also releasably mounted within the seal member to prevent ingress of liquid concrete during box formation. A spacer member is provided for those instances where the seal member is to be installed in the wall of a relatively thick-walled concrete box. Alternate means for releasably retaining the seal member to the mandrel are disclosed. Additionally, a series of such seal assemblies is disclosed for use in sealably attaching a pipe through a thick poured concrete wall, such as a basement wall.
