Abstract: The present invention relates to DNA compounds which encode human protein C activity. A variety of eukaryotic and prokaryotic recombinant DNA expression vectors have been constructed that comprise the novel protein C activity-encoding DNA and drive expression of protein C activity when transformed into an appropriate host cell. The novel expression vectors can be used to produce protein C derivatives, such as non- carboxylated, non-glycosylatedd, or non-hydroxylated protein C, and to produce protein C precursors, such as nascent or zymogen protein C, and to produce subfragments of protein C, such as active or inactive light and heavy chain. The recombinant-produced protein C activity is useful in the treatment and prevention of a variety of vascular disorders.

Abstract: A system for providing information to alter the software of an electronic data processor embedded in an electronic module includes a remote reprogramming module that conducts a sequence of operations to provide data to the processor which the processor uses to reprogram itself. The system employs a data link having a bi-directional transmission path connecting the processor and the reprogramming module. A controlled switching circuit is provided at each end of the transmission path. Under normal operating conditions, the transmission path is used to transit a function signal for a function performed by the electronic module. Periodically, the processor operates one switching network to capture the path for transmission of a reprogramming inquiry signal to the reprogramming module. At the same time, the function signal is diverted to an alternate path internal to the electronic module. When the reprogramming module detects a reprogramming inquiry, it operates the other switching circuit to gain access to the transmission path. Then, in response to commands from the processor, the reprogramming module undertakes the reprogramming sequence and transfers data to alter program information held in the memory of the processor. Thereafter, both the processor and the reprogramming module operate their respective switching circuits to restore the transmission path to its normal operational use for the transmission of the function signal.

Abstract: Cigarette filter rods (34) having individual pellets (208, 209, 210, 211) positioned at predetermined intervals therein are prepared by cutting a strand (59) of plasticized material into pellets which are then inserted into a web of filter tow (22). A wheel (50) having a series of grooves (52) is rotated within a rim-like housing (57), and introduction of a plasticized flavor-containing strand into each groove results in a cutting of the strand into pellets of the desired size. Each pellet is positioned within the moving web of tow. The web filter material (22) and the pellets (145) positioned within the web are introduced into a rod-making unit (14) wherein the rod is formed. The rate of feed of the strand, the rate of feed of the filter tow, the rate of rotation of the grooved wheel and the rate of pellet formation are controlled relative to one another such that pellets of well controlled size are positioned at predetermined intervals along the rod. Cigarette filter elements having well controlled amounts of flavorant contained therein can be made from the rods.

Abstract: A catalytic hydrocracking process wherein a hydrocarbonaceous feedstock and a liquid recycle stream is contacted with hydrogen in a hydrocracking reaction zone at elevated temperature and pressure to obtain conversion to lower boiling hydrocarbons. A liquid hydrocarbonaceous stream produced from the effluent of the hydrocracking reaction zone is fractionated to produce at least one liquid hydrocarbonaceous product stream and a liquid hydrocarbonaceous stream containing hydrocarbons boiling at a temperature in the boiling range of the feedstock and heavy polynuclear aromatic compounds. At least a portion of the liquid hydrocarbonaceous stream containing heavy polynuclear aromatic compounds is introduced into a zone of the divided-wall fractionation zone to produce a stream rich in polynuclear aromatic compounds. At least another portion of the liquid hydrocarbonaceous stream containing hydrocarbons boiling at a temperature in the boiling range of the feedstock is recycled to the hydrocracking reaction zone.
