A vapor compression system having a multi-stage compressor with a minimal number of ports located in the hermetically sealed compressor housing. A working fluid at suction pressure enters the compressor housing through a first port and is compressed to an intermediate pressure. The intermediate pressure refrigerant flows from the first stage compressor mechanism to the second stage compressor mechanism where it is compressed to a discharge pressure and discharged through a second port. The intermediate pressure refrigerant is in thermal communication with a heat exchange medium which is introduced into the compressor housing through a third port in the housing.

A retrievable packer assembly for use in operations into wellbores, wherein the packer assembly comprises a continuous mandrel with a valve body including seal cups to seal against an inner surface of a casing, and a gap defined between the valve body and the mandrel to permit or prevent circulation of fluid between the interior of the mandrel and a section of the casing above the seal cups in response to the movement of the valve body.

This invention relates to a method for producing components with internal architectures, and more particularly, this invention relates to a method for producing structures with microchannels via the use of diffusion bonding of stacked laminates. Specifically, the method involves weakly bonding a stack of laminates forming internal voids and channels with a first generally low uniaxial pressure and first temperature such that bonding at least between the asperites of opposing laminates occurs and pores are isolated in interfacial contact areas, followed by a second generally higher isostatic pressure and second temperature for final bonding. The method thereby allows fabrication of micro-channel devices such as heat exchangers, recuperators, heat-pumps, chemical separators, chemical reactors, fuel processing units, and combustors without limitation on the fin aspect ratio.

The invention refers to a device for fixing a tube member (1) in a cavity (2) of a patient. The device includes a body (3), which surrounds the tube member and has a casing (4) that at least partly forms an inner space (5). The body (3) is expandable by supplying a fluid to the inner space in such a way that the fluid in the inner space has a working pressure. Furthermore, the body (3) has, in a non-expanded state, a relatively small outer extent, which permits the introduction into said cavity (2), and in an expanded state, a relatively large outer extend, which permits fixing in said cavity by abutment with a contact pressure against a tubular wall (7) of the cavity. In order to ensure a tight abutment against the wall (7) of the cavity, the body (3) has such a geometrical shape that the contact pressure is substantially constant independent of variations of the working pressure within a normal working range.

An electrically and thermally conductive adapter for connecting a weld electrode to a tip holder portion of a welding device. The adapter has a first, threaded end, for removable engagement with a like-threaded receiving cavity in the tip holder. The threads may be of parallel configuration to minimize damage to the receiving cavity. The adapter has a second, preferably tapered end, for receiving a removable weld electrode. A passageway is preferably provided through the adapter for transporting cooling fluid to the electrode. An o-ring may be retained on the adapter and designed to engage with a groove in the receiving cavity in order to prevent leakage of cooling fluid from around the threads. The adapter is economical to manufacture and may be quickly and easily removed or installed to the tip holder. The adapter reduces damage to the tip holder commonly caused by the repeated changing of electrodes.
