Patent GB-8301319-D0 (GB)
Title: Fabric materials
IPC: D06C3/00
Filed: 1983-01-18
Abstract: A woven fabric material is formed from tapes of synthetic resinous material such as polypropylene, either the warp tapes or the weft tapes having discontinuous longitudinally extending localised weakened areas formed in them, for example discontinuous longitudinally extending grooves in the tapes. The woven fabric is then stretched by stretching longitudinally and at a raised temperature that set of warp tapes or weft tapes which does not have the weakened areas, thereby causing the tapes with the weakened areas to split at those areas and open up to take on the appearance of a network. The stretched woven fabric material is cooled in the stretched condition so that the final stretched woven fabric material obtained has a substantially greater area and a lesser overall thickness than the base woven fabric, i.e. the fabric before it was streched.

Abstract: PCT No. PCT/GB90/00604 Sec. 371 Date Sep. 25, 1991 Sec. 102(e) Date Sep. 25, 1991 PCT Filed Apr. 20, 1990 PCT Pub. No. WO90/12878 PCT Pub. Date Nov. 1, 1990.A novel enhancer, known as the K3'-enhancer, has been identified in the mouse immunoglobulin K locus, downstream of CK. The K3'-enhancer is B cell specific, is some sevenfold stronger than the K-intron enhancer and the region of the enhancer shows striking sequence homologies to the lymphotopic papovavirus, IgH and K-intron enhancers. The novel enhancer allows high level expression both in transfected cell lines and in transgenic mice, and may thus be used to enhance expression of genes in host cells, in vivo and in vitro. The novel enhancer is also found to increase somatic mutation of antibody genes in transgenic mice. The novel enhancer can also be use in gene therapy. Functionally equivalent enhancers are to be expected to occur downstream of CK of the immunoglobulin K locus of other species.

Title: Method of producing elliptic core type polarization-maintaining optical fiber
IPC: C03B37/012
Filed: 1989-05-26
Abstract: A method of producing an elliptic core type polarization-maintaining optical fiber comprises the steps of providing a glass rod comprising a cladding glass layer around the periphery of a core glass layer, the cladding glass layer having a softening point higher than the softening point of the core glass layer, removing two side surface portions of the glass rod by machining along the axial direction of the glass rod to form a machined rod noncircular in cross section, outside depositing fine silica glass particles on the periphery of the machined rod, followed by sintering to provide a support glass layer having a softening point higher than the softening point of the cladding glass layer, and drawing the thus obtained glass rod body as an optical fiber preform. Since the portion for constituting the core of the optical fiber is formed by machining, the core is permitted to have a high ellipticity. An optical fiber with the desired size and birefringence index is obtained by regulating the conditions of production.
