Title: Molecular cloning and clones of human b lymphotropic virus (hblv)
Inventor: JOSEPHS STEVEN F
IPC: C12Q1/70
Filed: 1987-08-11
Granted: 1993-09-21
Abstract: ABSTRACT OF THE DISCLOSURE        A clone of  Human  B  Lymphotropic  Virus  (HBLV), pZVH14  has  been  isolated  (from  the  peripheral blood leukocytes of six individuals)  and  characterized.   The clone  is  obtained  from  nucleic  acids  extracted from purified virus, and contains a 9.0 Kb HindIII fragment of HBLV .   HBLV contains a double-stranded DNA genome and is morphologically similar to some  members  of  the  Herpes family.    The   clone   is  lymphotropic and selectively infects freshly isolated human B cells, where it  induces the  appearance  of characteristic large refractile mono-nucleated or binucleated host cells.  The molecular clone of  the  present   invention  is  capable  of  in  situ hybridization with host cells infected with HBLV.   This clone,  therefore,  is  useful  as  a diagnostic probe  for HBLV-infected cells, as well as for the detection of viral antigens  or  antibodies  in  blood  samples  (using  an immunofluorescence assay or any other assay for antigens or antibodies which uses viral nucleic acids).  Molecular clone pZVH14 is also used in the detection of early virus infection of umbilical cord blood lymphocytes and spleen cells by in situ hybridization in culture.   The present invention is also capable of introducing genes into target cells  of  the virus  as  a  recombinant  DNA  virus  vector system.

Title: Method and apparatus for metering liquid samples
Inventor: MEYRAT PIERRE-ANDRE
IPC: G01F11/10
Filed: 1987-12-22
Granted: 1993-01-12
Abstract: A METHOD AND APPARATUS FOR METERING        LIQUID SAMPLES     ABSTRACT OF THE DISCLOSURE     First and second containers (R1; R2) are successively brought to a decanting station (C) in which the samples are metered. For this purpose, a piston (17) is mounted so as to be able to penetrate each first container (R1), which can be lifted, when it enters the decanting station (C). The quantity of sample in the first container (R1) is greater than the quantity to be precisely metered which is poured into the second container (R2) by means of a pouring assembly (24 to 36) situated above it. A pouring member (40) may be placed between the second container and the pouring assembly. Thus, when the first container acts as cylinder on the piston (17), a first quantity of the sample rinses the decanting circuit to eliminate any residue of a preceding sample, while the pouring member is located between the pouring assembly (24 to 36) and the second container, then an exactly metered quantity of the sample is poured into the second container after withdrawal of the pouring member (40).

Abstract: Sour water is treated to remove dissolved hydrogen sulfide by means of an aqueous chelated poly-valent metal solution in a continuous recirculating system, particularly an autocirculation system, having reaction and oxygenation zones.  The solution contains a small catalytic amount of chelated polyvalent metal, and the dissolved hydrogen sulfide is catalytically oxidized to sulfur in the liquid phase by means of dissolved oxygen in the solution.  The sour water feed to the reaction zone is diluted by a massive recycle of oxygenated solution from the oxygenation zone before the sour water is contacted with air or other oxidizing gas used for oxygenating the used solution.  A portion of the oxygenated solution containing chelated polyvalent metal is removed as the sweet water product, and replacement chelated polyvalent metal is added.  The operating variables are controlled to maintain in the solution a predetermined polyvalent metal content and an effective dissolved oxygen content, and also to maintain a predetermined residence time so as to obtain high efficiency of hydrogen sulfide removal.

Granted: 1993-04-13
Abstract: Abstract of the Disclosure A contact lens for an animal (such as an egg-laying hen) having a nictitating membrane.  The contact lens has a curved central region adapted to be disposed over and spaced from the cornea when the contact lens is in place in the eye.  The lens also includes a peripheral region, disposed about the central region and having a curvature opposite thereto (i.e., a "reverse curvature"), to fit snugly under the animal's outer eyelids to aid in retention.  An annular surface portion of the peripheral region is adapted to contact and rest on an annular region of the eye tissue disposed radially outward of the region at which the nictitating membrane joins the eye tissue.  The radius of curvature of the central region provides, along with the increased diamater of the outer annular surface portion, a chamber within which the nictitating membrane may move under the lens without interference from the lens.  The slope of the curvature of the interior surface of the central region is continuous with the slope of the curvature of the interior surface of the peripheral region at the junction between the central and peripheral regions.  A portion or the central region has a thickness greater than that of the peripheral region without forming any discontinuities in the exterior surface of the lens. The contact lens is also extremely thin.  An injection molding process for fabricating the contact lens is additionally provided.
