IPC: B01D71/68
Filed: 1986-05-12
Abstract: A mixture of two or more gases is contacted with a surface of a gas separation membrane and a gas having a different composition is removed from the vicinity of an opposite surface of the membrane, where the membrane is formed from a sulphonated polyarylsulphone or polyarylketone. The membrane may be a dense film or may be an asymmetric membrane. The process is particularly suitable for the separation of hydrogen from a hydrogen/nitrogen mixture when separation factors considerably in excess of 100 may be achieved together with an acceptable permeability. The membrane is preferably formed from a sulphonated polyarylethersulphone, for example one having repeat units of the formula
     where Ph' is a phenylene residue and at least some of the groups Ph are sulphonated and m is 1 or 2 and the value can differ along the polymer chain. Divalent metal salts give membranes of high permeability which have a good separation factor.

IPC: H01L23/44

Abstract: A circuit module that contains a planar array of chips has an improved fin assembly that transfers heat to a liquid coolant that is circulated through the fins in a single pass so that there is a tendency for the upstream edge of the fins to run cold and the downstream edge to run hot. The module can be immersed in the coolant. A shroud (53) on the fins confines the coolant flow to channels (54) defined by the fins, the shroud, and the base (50) of the fins. The fin assembly is constructed so that the coolant channels are narrowed as a function of the temperature of the liquid coolant, e.g. by tapering the channels in the direction of flow. The narrowing channels increase the coolant velocity and thereby improves the heat transfer at what would otherwise become the hot end of the module. The coolant velocity is increased at the appropriate rate to maintain equal cooling along the direction of coolant flow. 
     The narrowing channels can be combined with other techniques for improving heat transfer, and in one embodiment the fin assembly has sets of fins (60,61,62) spaced that increase in density along the direction of coolant flow. The increased fin density constricts the channels and thereby increases the coolant velocity.

Abstract: A magnetic refrigerator (10) has a rotating magnetic wheel (71) which includes a stack of spaced rings (67) of magnetic material. Heat transfer plates (65) of a high temperature heat extractor (22) are interleaved with the magnetic rings (67) and extend to solid heat transfer conduit which leads to a high temperature terminal (23). Superconducting magnet coils (47, 48, 52, 53) are mounted to provide a magnetic field through the magnetic wheel (71) at the position of the high temperature heat transfer plates (65). Low temperature extractor heat transfer plates (85) are positioned outside of the magnetic field and interleave with the rings (67) of the magnetic wheel (71) to transfer heat thereto which is conducted from a low temperature terminal (20) through a solid conduit. As the magnetic wheel (71) is rotated, heat is drawn from a load and conducted through the solid material of the low temperature heat extractor (21) to the magnetic wheel (71), is released when the material of the wheel (71) is subjected to the magnetic field and transferred to the high temperature heat transfer plates (65), and is thence conducted through the solid material of the heat transfer conduit to the high temperature terminal (23). Helium gas is sealed in the space surrounding the rotating magnetic wheel (71) to transfer heat between the rings (67) of the wheel (71) and the heat transfer plates (65, 85). Substantially all heat transfer in the magnetic refrigerator (10) is thus provided by conduction through a solid, allowing start-up of the refrigerator (10) without an initial charge of liquid helium to cool the refrigerator (10) to cryogenic operating temperatures.

Abstract: A thermal conductivity cell is described whose elements are well protected against short term temperature fluctuations, changes in flow rates, leaks, and vapor pressures of construction materials. The sample and reference chambers are formed within a relatively large copper block with a controlled thermal time constant. The thermal elements are isolated from the gas flow paths by porous metal plugs which are thermally "clamped" to the block. Element feed-throughs are potted in thermally conductive epoxy to minimize the effect of temperature gradients. Electron-beam welding and fluxless vacuum brazing are employed in joining operations.
