2092076 9205662 PCTABS00011 The appropriate one of a list of possible motion vectors is applied to each region of a video image. An image value for that region is determined for each of four successive fields, for each of the possible motion vectors. The values for the four fields are compared and when the values are substantially the same for a given vector it is assumed that that is the vector a...

This invention relates to a self-supporting tray-like product container and to a method and machine for making the container. In producing a product container, material requirement are imposed which are difficult if not impossible to meet with a single material, especially one which is readily thermoformable, and which for packaging of food product possesses the desired thermal distortion resistan...

This invention relates to a novel chartreusin derivative of the general formula (I): (I) and a salt thereof. This chartreusin derivative and a salt thereof have an excellent antitumor activity, which is exhibited even when the site of cancer inoculation and the site of drug administration are different. This invention further relates to a antitumorous composition containing the above-me...

The invention is a process for producing N-substituted glucamines, a process for oxidizing an N-substituted glucamine with an oxidizing microbe or extract thereof, and a process for oxidizing an N-substituted glucamine with an oxidizing microbe or extract thereof and reducing the oxidized N-substituted glucamine to an N-substituted-I-deoxynojirimycin. In addition, a one pot process for producing N...

2092002 9205186 PCTABS00011 Oligonucleotide analogs are disclosed wherein one or more phosphodiester linkages between adjacent nucleotides are replaced by a backbone linkage resistant to nucleases. The modified oligonucleotides are capable of strong hybridization to target RNA or DNA. These oligonucleotide analogs are useful in therapies which modulate gene expression using "antisense" or other sp...

The present invention teaches a method of producing butt welds between pipes or ducts of fluoropolymers, which are extremely chemically inert and which have continuous service temperatures in the range of 300 to 500 DEG F (149 to 260 DEG C) or more, by simultaneously applying infrared or radiant heat to the ends of the pipes or fittings to be welded but without touching the ends being radiated. Th...

Direct label probe compositions which stain DNA of a preselected single chromosome or region of a chromosome of a multi-chromosomal genome are provided that comprise mixed DNA segments which are covalently bound to fluorophore groups through linking groups. The mixed DNA segments are derived from the DNA present in the preselected chromosome or chromo- some region. These probe compositions can be...
