Abstract: A package and method of use for packaging temperature sensitive payloads during transport through environments having extreme temperatures. The package includes a segmented, flexible panel containing a plurality of phase change material segments. A pair of such panels may be used, with each panel being separately thermally preconditioned as a function of anticipated ambient temperature during transport. The panels may be formed by retaining phase change material segments between a pair of flexible sheets.

Abstract: The present invention is directed to a transport package which efficiently maintains payload temperature within a predetermined temperature range during delivery through regions having ambient temperatures outside the desired range. The transport package is used for transporting temperature sensitive materials and thermally protecting the materials from cold and hot ambient temperatures in a manner that does not require a power source or other mechanical devices. Aspects of the invention relate to a temperature maintaining packaging system having an outer container, thermal insulation materials and two or more different phase change materials.

Abstract: Virtual dedicated voice connections between parties 18, 19 to a packet switched system can be created by reserving capacity for such connections in the packet switched system. The capacity reservable by any one party is limited, to prevent oversubscription of resources in the packet switched. The system incorporates a call admission control processor 12, 17 for controlling access to the packet switched call routing system such that a voice call attempt is successful only if capacity for such a dedicated connection has previously been reserved. The capacity reserved for the virtual connections is made available for use by other traffic when not required for voice calls.

Abstract: A strip-shaped superconductor has a conductor structure containing at least one metallic substrate strip, a layer made of oxidic high Tc superconducting material of the AB2Cu3OX type; an oxidic buffer layer, which is arranged therebetween and which has adapted crystalline dimensions, and; a normal-conductive top layer that is applied to the superconductive layer. The buffer layer should be formed so that a transition resistance of no greater than 10?3 ?cm2 is formed at least in partial areas between the superconductive layer and the substrate strip. For example, suitable materials are of the La—Mn—O or Sr—Ru—O or La—Ni—O or In—Sn—O type.

Abstract: The invention relates to an analytical test element for analysis of a liquid sample (20), containing a channel (9) which is suitable for capillary transport of the liquid sample (20) and which is provided with an inlet opening (7) for the liquid sample (20) and with an air outlet opening (8). At least one test field (17) is arranged in the channel (9), spaced apart from the inlet opening (7). The test element (1) comprises a sample application site (4) which is closed with a seal and which is designed in such a way that, when the seal is opened, the sample application site (4) and the inlet opening (7) of the channel (9) are simultaneously open to the outside environment of the test element (1). The test element (1) can then receive the liquid sample (20) inside the channel (9) via the sample application site (4) and inlet opening (7), for analysis in the test field (17). The invention also relates to a test element magazine and to a system for analysis of liquid samples with at least one test element.

Abstract: The resistive current limiter contains an electrically insulating support body and at least one conductor track structure arranged thereon and having a conductor track made of high-Tc superconductor material. The conductor track has straight and curved conductor track segments. A maximum radii ratio v of 7 (v=ra/ri where ra=external radius, ri=internal radius) is to be maintained for the curved conductor track segments. The conductor track is advantageously patterned from a layer which is made of the high-Tc superconductor material and is applied on the support body.

Abstract: An apparatus for delivering current to a cooled electrical device. The apparatus includes at least one electrical line having a first end at a first temperature and a second end at a second temperature being lower than the first temperature. The second end is provided for connection to the cooled electrical device to deliver current to the cooled electrical device. The cooled electrical device is preferable a superconducting device. At least a portion of the electrical line includes a part of a cold head. The part of the cold head is preferably a regenerator or a pulse tube of a pulse tube cooler.

Abstract: The invention relates to a rechargeable lithium-ion cell, a method for its manufacture, and its application. The cell is distinguished by the fact that it has a metallic housing (21) which is electrically insulated internally by two half shells (15), which cover electrode plates (8) and main output tabs (7) and are composed of a non-conductive material, where the metallic housing is electrically insulated externally by means of an insulation coating. The cell also has a bursting membrane (4) which, in its normal position, is located above the electrolyte level of the cell (1). In addition, the cell has a twisting protection (6) which extends over the entire surface of the cover (2) and provides centering and assembly functions for the electrode package, which comprises the electrode plates (8).

Abstract: An Li/LiMn.sub.2 O.sub.4 secondary cell employing a SWING system (i.e., of the "rocking chair cell" type) includes a positive electrode formed as a metal gauze-reinforced, rolled electrode, and a negative electrode formed by impregnating a nickel foam with a paste of Li-intercalating graphite. Such electrodes are from 3 to 4 times thicker than the thin-film electrodes fabricated with prior, knife-coating techniques and employed in wound cells, and are therefore particularly suitable for constructing prismatic cells. By prerolling the as yet empty nickel foam to specific thicknesses, the capacity per unit area of the negative electrode can be tailored to that of the positive, rolled electrode. By rerolling the impregnated nickel foam, optimal energy density and electrode capacity is achieved, at a porosity of from 50 to 60%.

Abstract: A spiral-wound galvanic cell is based upon a lithium system with a nonaqueous electrolyte, and includes a positive electrode, the carrier of which is clamped within the slit of a simple metal splint which serves as the winding mandrel and current collector. Contact with the metal splint is established by a leaf spring associated with the housing cover, which then serves as the positive terminal post for the cell. A high specific contact pressure is developed at this connection by providing the leaf spring with a punched hole which rests on thicker top portions of the metal splint. A small metal plate pressed through the lithium electrode and its separator establishes electrical contact between the lithium electrode and the interior wall of the housing vessel, which then serves as the negative cell pole.

Abstract: An apparatus for treating uremic patients by means of ultrafiltration, in which the withdrawn blood is separated by means of a hemofilter into plasma water and residual blood and the plasma water is exchanged in an exchange device. The latter comprises two chambers I and II, separated from one another by a flexible or movable partition, of which chamber I is filled with fluid and can additionally receive the plasma water, and chamber II contains substitution solution. By exerting pressure in the partition, a suction is caused in chamber I and a pressure in chamber II, so that chamber I can take up the plasma water, while the same volume of substitution solution is released from chamber II.
