Title: Optical fiber bundle having improved terminal structure
Inventor: MOGI MASAHARU
IPC: F21V8/00
Filed: 1988-01-13
Granted: 1992-09-29
Abstract: ABSTRACT    At the end of an optical fiber bundle,  a reflecting member is provided to deflect  the  emitted  light  from a portion of the fibers in a direction transverse to the axis of the fiber bundle, thereby enhancing the ability of the fiber  bundle  to  irradiate  lateral  surfaces  while  the undeflected light maintains the irradiation of a surface confronting the axial end face of the fiber bundle.

Title: Corrosion protected tension member for use in prestressed concrete and method of installing same
Inventor: NUETZEL OSWALD
IPC: E04C5/12
Filed: 1988-03-11
Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE     A corrosion-protected tension member, such as a tendon for prestressed concrete with post-tensioning, is made up of a bundle of individual tension elements, such as strands, ar-ranged within a tubular envelope.  The tension member extends between anchoring devices, each forming an anchor region for the tension member with a free region located between the anchor regions.  In the free region, the tubular envelope is formed of a sheathing tube.  Each individual element is located within a separate sheathing duct, and a corrosion-protection mass fills the space within the ducts about the elements.  The open volume within the sheathing tube around the sheathed elements is filled with cement mortar.   In the anchor regions, the tubular envelope includes an anchor tube enclosing an anchor pot,  The anchor pot has a base with openings through which the individual elements pass in a sealed manner.   The anchor pot is filled with a corrosion-protection mass.  Accordingly, the individual elements are axially movable and retensionable along their entire lengths.          The sheathing ducts and  the anchor pot separate the cement mortar from the individual tension elements in the free region extending between the anchor pots.

Title: Monoclonal wee-1 b-cell line
Inventor: WEE RICHARD K
IPC: C12N5/0781
Filed: 1988-09-16
Granted: 1992-11-03
Abstract: Form 24 ABSTRACT   A novel B-cell line (designated WEE-1) has been artfully cloned from human peripheral blood. By innovative isolation procedures and specialty phenol-red free culture medium, the cloned cells grow into large clusters. Under light microscopy, these fusiform cells exhibit apical cytoplasmic projections, and irregular large nuclei. By electron microscopy (EM) the cell reveals abundant mitochondria, stratified rough endoplasmic reticulum (RER), ribosome lamella complex, and a heterochromatic thick-rimmed, irregular nucleus containing prominent nucleoli. The cells are positive for immunoglobulin (Ig) G and M heavy-chains, and Kappa (K) light-chain, and they express tartrate-resistant acid phosphatase (TRAP), Epstein-Barr virus (EBV) antigen, and abnormal karyotype of 45, X, -Y, +12q. When cell DNA was hybridized with recombinant probes specific for immunoglobulin heavy-chain joining region (JH), kappa and lambda light-chain constant regions (CK and C.lambda.), autoradiographs reveal rearranged JH, and CK genes and germ line configuration of C.lambda.. Upon immunophenotyping by flow cytometry, the WEE-1 cells express a sequence of human leucocyte antigen (HLA) class II antigens DR+DP+DQ+. These distinctive cells exhibit the CD19 and CD20 pan-B cell antigens CD23 and CD71 receptors for IgE and transferrin, but lack the common acute lymphocytic leukaemia antigen (CALLA or CD10), haematopoietic progenitor cell antigen (HPCA-1 or CD34), terminal deoxynucleotidyl transferase, and the common myelomonocytic and T-cell lineage antigens. The WEE-1 cell line is an invaluable tool for the study of B-cell development and differentiation, and acquisition of a non-toxic 21 kilodaltons (Kd) protein designated blood tumour necrosis factor (BTNF or TNF-.gamma.) for use in biological response modifications. Interaction of these unique cells with other haematopoietic cell lines will increase our comprehension of host defense and immunity, cell-cell communication, intracellular processing of proteins, and functional significance of histocompatibility.

Title: Assay using template-dependent nucleic acid probe reorganization
Inventor: BACKMAN KEITH C
IPC: C12Q1/00
Filed: 1988-12-09
Granted: 1993-10-19
Abstract: Abstract of the Disclosure Target nucleic acid is detected by reorganizing an excess of two complementary pairs of single stranded probes, which hybridize to contiguous target sequences. Nucleic acid in the sample is annealed to the probes, and contiguous sequences are ligated to form complementary detectable fused probes complementary to the original target, and the fused probes serve as a template for further fusions.  The reorganized species being detected is increased at a geometric rate by cycles of annealing probes to the target, ligating the annealed probes in a template-dependent manner, and separating the fused probes from the template to form new templates.

Inventor: BOCK WOJTEK
IPC: G02B6/42

Granted: 1992-12-01
Abstract: ABSTRACT OF THE DISCLOSURE:         There is disclosed a method anal a system for laying out  optical  fibres  across  an  aperture  in a wall  separating a high pressure zone  from a low pressure zone.  It  involves a plug member sealingly mounted across the aperture and formed with  an  axial  through  fibre  passage having a conical  first portion and a second portion of constant cross-section. A co-nical wedge member is freely inserted into the first passage portion and is formed with a series of grooves on its outer surface leading into the second passage portion. A plurality of optical fibres are divided into fractions and each fraction is received into one of the grooves; all fibres being there-after collected into the second passage portion. Plastics ma-terial is introduced in the grooves and in the second passage portion to completely embed the fibres while adhering to the walls  of the grooves  and of the second passage portion.  In this manner, the frictional resistance of the plastics material is greatly increased,  allowing an appreciably larger pressure differential between the two pressure zones.

Abstract: In a scroll apparatus for fluid compression, two interfitting involute scroll elements with inner wall surfaces, each defined by an inner tip portion, an adjacent intermediate portion, an outwardly tending arcuate portion for periodic engagement in moving line contact with the inner tip of the other respective scroll element, and an involute portion extending from the arcuate portion to an outer end of the scroll element.  When the involute scroll element inner tip is in moving line engagement with the arcuate portion of the other element, the scroll elements cooperate to define sealed final compression chambers of decreasing volume bounded by the intermediate portion of the scroll elements adjacent the respective inner tips, providing an extended duration of final compression as compared to a scroll apparatus having unmodified scroll elements.  Furthermore, the arcuate portions and intermediate portions define an involute scroll wrap element having a thickened inner tip portion for increased strength and improved discharge flow from the final compression chambers to the discharge port.
