Abstract: A multi-layered compressor housing and method of manufacture is provided. The housing defines an interior space and includes first and second layers having first and second major surfaces respectively. The first and second layers are secured together by the frictional engagement of the first and second major surfaces which each substantially enclose the interior space defined by the housing. The housing may be manufactured by placing first and second layers of sheet stock material in mutual facing engagement wherein the two layers are relatively moveable. The first and second relatively moveable layers are then simultaneously formed into a non-planar shape defining at least a portion of the housing. A compressor is then mounted in the housing and the housing is hermetically sealed. The simultaneous forming of the first and second layers into a non-planar shape causes the frictional engagement of the layers whereby the layers are secured together.

Abstract: An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. The apparatus and methods further include a tube frame removably connected to the cassette and configured to hold a plurality of tubes in a position to be connected to tubes in the portable housing.

Abstract: The invention provides devices, device configurations and methods for improved sensitivity, detection level and efficiency in mass spectrometry particularly as applied to biological molecules, including biological polymers, such as proteins and nucleic acids. Specifically, the invention relates to charged droplet sources and their use as ion sources and as components in ion sources. In addition, devices of this invention allow mass spectral analysis of a single charged droplet. Further, the charged droplet sources and ion sources of this invention can be combined with any charge particle detector or mass analyzer, but are a particularly benefit when used in combination with a time of flight mass spectrometer.

Abstract: The invention provides devices, device configurations and methods for improved sensitivity, detection level and efficiency in mass spectrometry particularly as applied to biological molecules, including biological polymers, such as proteins and nucleic acids. In one aspect, the invention relates to charged droplet sources and their use as ion sources and as components in ion sources. In another aspect, the invention relates to charged droplet traps and their use as ion sources and as elements of ion sources. Further, the invention relates to the use of aerodynamic lenses for high efficiency ion transport to a charge particle analyzer, particularly a mass analyzer. Devices of this invention allow mass spectral analysis of a single charged droplet. The ion sources of this invention can be combined with any charge particle detector or mass analyzer, but are a particularly benefit when used in combination with a time of flight mass spectrometer.

Abstract: A storage rack system with tapered storage rack arms and a protective device for covering the exposed outer ends of the storage rack arms. The tapered storage rack arms have tapered lower sides and may have upwardly inclined upper sides. The tapered lower sides allow material to be loaded onto subjacent storage rack arms without scraping or colliding with the lower sides or exposed outer ends of the tapered storage rack arms located above. The protective device utilizes an arcuately shaped member attached to a support member. The support member of the protective device is attached to the exposed outer end of the storage rack arm of the storage rack unit. The protective device prevents collision with the exposed outer ends of the storage rack arms by personnel, customers, equipment and material.
