IPC: B04B11/02
Filed: 1999-11-10
Abstract: Upon use of a nozzle centrifuge for separating oil, water and sand from a mixture thereof separated water and sand is continuously removed through nozzles (12), which are arranged at the periphery of the rotor of the nozzle centrifuge. Separated oil is discharged through a central outlet (13-15) in the rotor. Through a space (17) in the rotor, which communicates with the radially outer part (7b) of the rotor separating chamber (7), water may either be supplied under pressure to the rotor or be discharged from the rotor for maintaining an interface layer, which is formed in the separating chamber (7) between separated oil and separated water, at a predetermined radial level (22). A supply device (23-25) and a discharge device (26, 27) are adapted to supply to the rotor and discharge from the rotor, respectively, only so much water that is required for said purpose. The discharge device (26, 27) is separated from the supply device (23-25), so that discharged water need not be subjected to the pressure generated by or maintained in the supply device (23-25).

Title: Gene encoding labyrinthin, a marker for cancer
Inventor: RADOSEVICH JAMES A
IPC: C07H21/04
Filed: 1999-03-11
Abstract: A cDNA molecule that encodes a protein designated Labyrinthin (Lab) is isolated and its nucleotide sequence is determined. The protein, or peptides derived from the protein, are markers useful to define novel classes of cancers. Diagnostic assays for these cancers use antibodies to Lab or nucleotide probes that hybridize with the lab gene or a fragment therefrom.  Vaccines useful either to prevent recurrence of cancers in subjects who test positive for Lab (or lab), or to prevent initial occurrence of cancer, use proteins or peptides derived from Lab. Expression of Lab via immunogenic assays is used to monitor effects of cancer treatments. Antisense molecules against lab are used in treatments. Sense molecules of lab are used to restore lost lab function in diseased normal cells, for example, gland cells.
