Abstract: A method for providing EMI shielding to an electronic circuit board using an electrically-conductive thermoplastic sheet containing a pre-applied electrically-conductive adhesive composition is disclosed. The adhesive composition is fluent and form-stable, and comprises a silicone adhesive, a compatible silane and electrically-conductive particles or fibers. The adhesive is conveniently pre-applied to the thermoplastic sheet and shipped to the customer for attachment to the integrated circuit board.

Abstract: A compressor is provided suitable for compressing natural gas from a pressure associated with a residential gas supply to a pressure suitable for an automotive gas tank. The compressor utilizes a par of pneumatic cylinders driven by a hydraulic cylinder to compress the gas in a multi-stage process. Various embodiments are provided with respect to the gas compressor portion and the drive portion. A pressure boost system is also provided which utilizes an internal control valve and internal orifice through the piston of one of the pneumatic cylinders.

Abstract: A piston-slipper assembly and method for assembling a piston-slipper assembly for use in a hydraulic apparatus such as a piston motor or piston pump. The assembly contains a piston and a slipper, and at least one of the piston or the slipper includes a ball and the other includes a socket. The ball is retained in the socket without crimping, swaging or bending of the socket.
