Abstract: An assembling machine with a feeder is provided. The feeder feeds receiving components into an assembler, where a moveable coupling mechanism couples attaching components to the receiving components. Transporting mechanisms coupled to a plurality of drive trains deliver the receiving components across the feeder table and to the assembler. The transporting mechanisms alternate between a plurality of speeds so as to deliver the receiving components to the assembler such that the moveable coupling mechanism may operate at a continuous, periodic rate.

Abstract: Supported stereospecific catalysts and processes for the stereotactic propagation of a polymer chain derived from ethylenically unsaturated monomers which contain three or more carbon atoms or which are substituted vinyl compounds, specifically alpha olefins, particularly the polymerization of propylene to produce syndiotactic or isotactic polypropylene. The supported metallocene catalyst comprises a stereospecific metallocene catalyst and a co-catalyst component comprising at least one of an alkyl alumoxane and an alkylaluminum compound. Both the metallocene catalyst and the co-catalyst are supported on a particulate silica support comprising silica particles having an average particle size of 5–40 microns and an average effective pore size of 50–200 angstroms. The silica support further has a differential pore size distribution of a pore volume of at least 0.01 cm3/g. within a range having a maximum pore width of no more than 300 angstroms.

Abstract: The present invention is directed to compounds useful in the treatment of diseases associated with prenylation of proteins and pharmaceutically acceptable salts thereof, to pharmaceutical compositions comprising same, and to methods for inhibiting protein prenylation in an organism using the same.

Abstract: Method, apparatus and article of manufacture for detecting a physical condition in a pipeline. In one aspect, there is provided a method of detecting a physical condition in a pipeline by obtaining vibration data from the pipeline which is representative of the physical condition. In one embodiment, physical condition is any corrosion in the pipeline.

Abstract: A process for the preparation of a supported metallocene catalyst incorporating metallocene and co-catalysts components on a support. There is provided a particulate catalyst support material in which an alumoxane co-catalyst is incorporated onto the support particles and contacted with a dispersion of a metallocene catalyst in an aromatic hydrocarbon solvent. The metallocene solvent dispersion and the alumoxane-containing support are mixed at a temperature of about 10° C. or less for a period sufficient to enable the metallocene to become reactively supported on the alumoxane support material. The supported catalyst is recovered from the aromatic solvent and then washed optionally with an aromatic hydrocarbon and then sequentially with a paraffinic hydrocarbon solvent at a temperature of about 10° C. or less. The washed catalyst is dispersed in a viscous mineral oil having a viscosity which is substantially greater that the viscosity of the paraffinic hydrocarbon solvent.

Abstract: Process of preparing silica-supported catalysts. A support material comprising silica particles impregnated with an alumoxane co-catalyst with at least one-half of the co-catalyst disposed within the internal pore volume of the silica is contacted with a dispersion of a metallocene catalyst in an aromatic solvent. The dispersion and support are mixed at a temperature of about 10° C. or less to enable the metallocene to become reactively supported on and impregnated within the alumoxane-impregnated silica particles. The supported catalyst is recovered from the aromatic solvent and washed with an aromatic hydrocarbon and then a paraffinic hydrocarbon at a temperature of about 10° C. or less. The washed catalyst is dispersed in a viscous mineral oil.

Abstract: A data structure represents a textual string. The data structure is in the form of an annotated tree that includes nodes, each node having at most one parent node and a set of unordered, immediate constituents, each immediate constituent of a node being identified by a semantic relation to the node.

Abstract: The present invention is directed to compounds useful in the treatment of diseases associated with prenylation of proteins and pharmaceutically acceptable salts thereof, to pharmaceutical compositions comprising same, and to methods for inhibiting protein prenylation in an organism using the same.

Abstract: An electronic computing device for providing a plurality of possible test grades on a scale of zero to one-hundred to a user includes a case and a computer mounted within the case. The computer includes a keyboard through which the total number of problems presented on a test is manually entered and a processor responsive to the total number of problems entered through the keyboard for generating a plurality of signals corresponding to possible test grades and for generating display signals corresponding to the possible test grades. A display associated with the case displays the possible test grades so that the user is visually informed of possible test grades based upon the total number of problems presented on the test.

Abstract: A bioprosthetic valve stent is fabricated from a hydrogel, and a bioprosthetic heart valve comprises such a stent. A method for fabricating a hydrogel bioprosthetic valve stent comprises filling a mold cavity with a solution of a hydrogel, allowing the hydrogel to solidity, removing the solidified hydrogel from the mold cavity and hydrating the hydrogel.

Abstract: A testing apparatus in the form of a dip card 10 for testing a fluid medium includes a housing incorporating a grid member 16 provided with openings or tracks 20 for receiving test strips 18. At least one capillary tube 28 communicates between the exterior of the housing and an opening or track 20 in the grid member. The capillary tube 28 enables fluid to pass to a test strip 18 located in the opening 20 in the grid member 16.

Abstract: A bioprosthetic valve comprising a support ring having three spaced apart end stops projecting upwardly therefrom, a stent post ring having three spaced apart stent posts pivotally connected thereto and adapted to engage respective ones of the end stops so as to permit outward pivoting of the stent posts and to prevent inward pivoting thereof, a leaflet valve having three generally triangular leaflets defining respective cusps, the leaflets being joined at respective commissures, and a sewing ring for attaching the leaflet valve to the stent post ring and support ring.

Abstract: A scent alarm device which includes a housing and a spray canister of an odorant, such as butyl mercaptan, supported within the housing utilizes a mechanism for intermittently dispensing odorant from the canister upon the occurrence of a predetermined event. The spray canister has a depressible release valve for releasing canister contents upon depression of the valve, and the depressing mechanism is adapted to repeatedly depress the canister release valve in an intermittent fashion. The device may utilize a canister having a height within a range of canister heights, and if desired, the device may be interfaced with a number of other alarm systems, such as a smoke or heat detector or used to alert an individual that household electrical power has been shut off.
