Abstract: New compositions, titanium-ligand complexes and arrays with pyridyl-amine ligands are disclosed that catalyze the polymerization of monomers into polymers. These catalysts with titanium metal centers have high performance characteristics, including high styrene incorporation into ethylene/styrene copolymers.

Abstract: A cannula for use in transferring small volumes of fluid materials, such as in a parallel reaction process. The cannula comprises a long thin needle having various end (port) configurations, and an adapter for connecting the needle to a fluid line. The adapter may include the combination of a reservoir and transition, or simply a transition.

Abstract: New ligands and compositions with bridged bis-aromatic ligands are disclosed that catalyze the polymerization of monomers into polymers. These catalysts with metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene into isotactic polypropylene.

Abstract: An ethylene/?-olefin copolymer comprising a component produced by a non-single-site polymerization catalyst and a component produced by a single-site polymerization catalyst, its preparation and use are described. The copolymer has an ?-olefin content of 5 to 20 percent by weight aud shows at least two CRYSTAF peak temperatures differing by at least 15° C. and/or at least two DSC melting peak temperatures differing by at least 15° C.

Abstract: A video identification verification system has a light tray for insertion of an ID card. The card when inserted has its top surface recorded on a video recorder. The image of the person presenting the card is also recorded along with a time/date stamp. The light tray has side wall diffusers and associated LEDs that provide even illumination to the light tray so as to facilitate recording of ID cards of all types.

Abstract: A parallel reactor system including a reactor and vessels in the reactor for holding reaction mixtures, and a cannula for introducing fluid reaction material into the vessels. A robot system is operable to insert the cannula into cannula passages in the reactor for delivery of reaction materials, including slurries, to respective vessels, and to withdraw the cannula from the cannula passages after delivery. Related methods are also disclosed.

Abstract: An apparatus for parallel processing of multiple reaction mixtures comprises a plurality of reactor vessels for holding reaction mixtures at pressures of at least about 15 psig. Cannula passages communicate with respective vessels, and a cannula is adapted to be inserted into each cannula passage. A sealing mechanism, comprising a valve and a seal, in each cannula passage maintains a respective vessel sealed when the cannula is inserted into and withdrawn from the cannula passage. A robot system is operable to insert the cannula to a location where a distal end and port of the cannula are past the open valve and seal, and to withdraw the cannula. Methods for transferring fluid reaction material to and from a series of pressurized vessels, establishing fluid communication between a cannula and a vessel of a combinatorial chemistry reactor and establishing fluid communication between a cannula and a series of pressurized vessels of a combinatorial chemistry reactor are also disclosed.

Abstract: A structure formed from a new family of polyhedral models and rigid structures. The structure having discrete interior and exterior elements, and is formed from a plurality of rigid-stellate polygonal modules. Each rigid-stellate polygonal module has at least three polygonal structures coupled to a rigid stellate connector or axis by a base edge. The angle subtended between each of the at least three polygonal structures may be varied by changing the connector.

Abstract: An improved glass block construction unit having an electrical assembly (13) integrally attached through a glass wall (2) of the unit, thereby allowing the unit to be self illuminating.

Abstract: A variable polyhedral framework made from at least two joined tetrahedrons hinged at their coincident base edges, which may thereby move easily through and be made rigid in many different configurations.

Abstract: An exercise device for improving poor visual acuity is disclosed in which a subject must identify randomly chosen figures of minimal visual stimulus projected in a darkened chamber. Earphones are provided to aid in the isolation of the subject and provide audio feedback. The device provides effective treatment for certain eye conditions involving poor acuity and is particularly effective in treating the eye condition known as amblyopia.

Abstract: A new type of robotic device is disclosed, using several cable trussed compression members in concert. The cable trussed compression members are deformed along the length of their central compression mast, by the lengthening and shortening in concert of all of the cables of each cable trussed compression member, through the use of motors. Weights traveling on tracks, or fluid filled hoses, are used in addition to the deformation of the cable trussed compression members, to change the location of the center of gravity of the entire assembly, thereby enhancing the balancing and stability of the robotic device. Additional known mechanical and electrical devices may be used in conjunction with the several cable trussed compression members.

Abstract: A family of modular construction units, formed from a plurality of curved surfaces, which may be interconnected with others of like shape to form a structure defining a volume of space.
