  • Publication number: 20150140418
    Abstract: A monoblock battery assembly including an electrode assembly having at least one positive electrode, at least one negative electrode, one or more insulative sheets between the at least one positive electrode and the at least one negative electrode, and an outermost insulative layer which substantially encases the at least one positive electrode, the at least one negative electrode, and the one or more insulative sheets. A housing having a cavity for receiving the electrode assembly is provided and a cover is sealingly attached to the housing. A bussing is electrically connected to the at least one positive electrode and the at least one negative electrode of the electrode assembly.

  • Patent number: 5967921
    Abstract: A hydraulic tensioner is designed for low cost and ease of manufacturing. A housing has a bore and a sleeve member received within the bore. A piston is slidably received within the sleeve member, forming a high pressure fluid chamber with the sleeve member. The housing can be constructed of inexpensive materials such as aluminum or plastic. The piston and sleeve member are constructed of drawn metal. The housing may be formed by injection molding. The sleeve member and other components of the tensioner may be assembled within the tensioner by inserting them into the mold during the injection molding process.
