摘要:
A compression chamber is formed by two end walls (10) and a flexible tubular member (11) extending between the end walls (10). The flexible tubular member (11) is formed from an inner tube (12) of air impermeable material and an outer tube (13) of a braided material. The inner tube (12) is unstressed when the chamber is filled with oxygen or air and the outer tube (13) bears the pressure load.
摘要:
An inflation device for a buoyancy body such as a life jacket or life raft having a pressurized gas cylinder mounted within the buoyancy body and including an actuator, preferably in the form of a rotatable shaft, which projects from the interior to the exterior of the body so that it can be used to cause release of gas into the body and is operable from the exterior of the inflation device.
摘要:
Methods are provided for conducting specific binding assays to determine the concentration or presence of at least one analyte in a sample. Dendrimer-reagent preparations with particular analyte specificities are mixed in solution with a sample to form dendrimer-reagent-sample complexes. The complexes are then immobilized on a solid phase. Immobilization is facilitated by coupling specific binding assay reagents such as polypeptide receptors or analytes with water soluble polymers. Such water soluble polymers, for example star polymers such as dendrimers, provide production advantages of lot-to-lot uniformity and homogeneity, and can enhance sensitivity due to low non-specific binding to the solid phase.
摘要:
A pump comprises a flexible container (11) filled with a fluid and having a fluid inlet (104) and a fluid outlet (105), and a constricting device (12), preferably in the form of a braid tube, conforming the container (11) to a generally circular cross-section and operable cyclically to reduce the diameter of the container (11) to expel fluid from the outlet and then allow the diameter to increase with fluid entering the inlet to refill the container (11). Such a pump can be suspended in the sea between an anchor and means for converting energy from the sea into a force acting on said constricting device, for example, a float, to cause the constricting device to reduce the diameter of the container (11) to expel fluid from the outlet (105), and then passing the expelled fluid to do work such as drive a generator (121).
摘要:
An inflatable tube (10) in a fascine is provided with a cover (11) of a braided material to provide significant strength. An outer cover (12) of KEVLAR™ may also be provided. The braided cover (11) and the inflatable tube (10) are held at the ends of the tube by a clamping mechanism (17, 18, 19) and a cylinder (40) of inflation gas is supported within the tube (10), when the tube (10) is inflated.

摘要:
Compositions including a liquid or liquid-like carrier and first and second particles dispersed therein. The first and second particles differ from each other in at least one surface chemistry property, such as hydrophobicity. The gel compositions can be used in a variety of applications, including the separation of blood samples into component fractions. Processes for producing gel compositions having desirable properties are also provided.
