The storage device includes a storage chamber enclosing a storage space where oxidizable materials may be placed and a differentially permeable membrane. The differentially permeable membrane allows at least one selected gas to pass therethrough while inhibiting at least oxygen from passing therethrough. The differentially permeable membrane is in fluid communication with the storage chamber such that the at least one selected gas is allowed to pass through the differentially permeable membrane flows into the storage chamber. An air mover, preferably a compressor, feeds gases to the differentially permeable membrane. A cooling element is provided for cooling the temperature within the storage chamber below that of the ambient temperature. The level of oxygen within the storage chamber is thus reduced relative to the level of oxygen in the atmosphere.Type: GrantFiled: November 8, 2002Date of Patent: January 11, 2005Assignee: American Moxie, LLCInventors: Lawrence Kunstadt, Peter Carlson

Patent number: 6752856Abstract: An assembly for removing aerosol from crankcase gasses being returned to an air intake manifold is generally shown at and includes a housing having a housing wall defining a top portion and a base with at least one drain. An inlet line extends through the housing wall communicating with a crankcase. An outlet line extends through the top portion for communicating with an air intake manifold. An inertial separator generally shown at is attached to the inlet line and has a screen through which the crankcase gasses pass and an impacter plate for obstructing aerosol suspended in the gasses. A sheet wound in spaced convolutions to define a spiraled path from the exterior to a central space conveys gasses from the inertial separator to the central space. A thermal interception tube located in the central space receives gasses and has a tube wall for gasses to pass therethrough and an opening at one end for egress of gasses.Type: GrantFiled: April 29, 1999Date of Patent: June 22, 2004Assignee: Caterpillar Inc.Inventor: Russell R.

Patent number: 6638330Abstract: In a device for filtering the intake air of internal combustion engines, including a tubular housing (2) with one filtering cartridge (3) fixed at an end by means of support means (4) provided with an inlet opening (5) and fit to support the housing (2) in correspondence of a lower opening (9) thereof, the filtering cartridge (3) is fixed to the support means (4), near the edges of the opening (5) so forming a single body, and is internally provide with air deflectors (6) fixed at the free end of the filtering cartridge (3) in such a way that the air flow coming from the opening (5) is forced by the air deflectors (6) to pass through the filtering cartridge (3) and comes out from the device (1) through an outflow opening (7), passing through the space between the filtering cartridge (3) and the external housing (2).Type: GrantFiled: June 12, 2002Date of Patent: October 28, 2003Assignee: BMC S.R.L.Inventor: Gaetano Bergami

Patent number: 6547844Abstract: The present invention has an object to improve the efficiency of collection of solidification constituents and solids in exhaust gas and to prevent early blockage of the filter without damaging the vacuum pump. In an exhaust path 48a, a vacuum pump and exhaust gas filtration device are provided. This exhaust gas filtration device is constituted by a trap device, pre-filter and filter. The pre-filter reduces the exhaust gas flow rate flowing through the interior of the exhaust path by controlling the exhaust gas flow path in the vessel. The aforesaid exhaust path is constituted by connecting this vacuum pump, trap device, pre-filter and filter which are arranged in this order from the side of airtight vessel and connected through piping if required.Type: GrantFiled: December 12, 2000Date of Patent: April 15, 2003Assignee: Anelva CorporationInventors: Toshihiro Rikyuu, Keisuke Nagakura
