Abstract: In hydrodynamic bearings it is necessary for the lubricant leaving the lubricant film to be cooled. The self-sufficient, reliable operation of the system is only ensured if the transport of lubricant can be generated and maintained by the bearing itself. For this purpose the lubricant is taken from the contact surface of the moving component (2) into a pumping gap (13), recessed in the stationary component (4), which exhibits a strong constriction (17) in the direction of movement by a graduation (16). This pumping gap (13) may be machined directly in the contact surface of a bearing segment or in a separate component. A part of the lubricant stream which enters the pumping gap (13) is removed in front of the constriction (17) through an appropriate lubricant discharge duct (14). This branched lubricant stream (19) represents the delivery quantity of the pumping gap (13). The remainder of the branched lubricant stream flows on through the lubrication gap (18). The pumping pressure corresponds to the pressure built up hydrodynamically in the pumping gap (13).

Abstract: A method and system for locating possible error or fault sites in a circuit or system. A set of nodes are chosen, using error models in some embodiments. By applying X values to the set of nodes in conjunction with three valued logic simulation output responses between the circuit and the specification are determined. Based on the comparison of the output responses between the circuit and the specification, an error probability can be assigned to the set of nodes. A ranked set of nodes is thereby produced with the highest ranked set of nodes being the most likely error or fault site.Furthermore, by determining the relationship of the inputs to the set of nodes to the outputs of the set of nodes in conjunction with test vectors and output responses determined in the specification, an error probability can also be assigned to the set of nodes. Use of symbolic logic variables can assist in determining the relationship of the inputs to the set of nodes to the outputs of the set of nodes.

Elastic deformation of the at least one protrusion is caused. The other protrusion is rotatable relative to the nut and force can be transmitted in the axial direction between the threaded bolt and nut. The protrusion is embodied with an axially protruding extension which extends to approximately the plane of the surface of contact of the nut with the contacting surface.

Abstract: This invention provides novel methods for the formation of biocompatible membranes around biological materials using photopolymerization of water soluble molecules. The membranes can be used as a covering to encapsulate biological materials or biomedical devices, as a "glue" to cause more than one biological substance to adhere together, or as carriers for biologically active species. Several methods for forming these membranes are provided. Each of these methods utilizes a polymerization system containing water-soluble macromers, species, which are at once polymers and macromolecules capable of further polymerization. The macromers are polymerized using a photoinitiator (such as a dye), optionally a cocatalyst, optionally an accelerator, and radiation in the form of visible or long wavelength UV light. The reaction occurs either by suspension polymerization or by interfacial polymerization. The polymer membrane can be formed directly on the surface of the biological material, or it can be formed on material, which is already encapsulated.
