Title: Lining of metallic pipe
Inventor: WHITE GEORGE
IPC: B29C63/34
Filed: 1991-05-01
Abstract: ABSTRACT OF THE DISCLOSURE           An improved method of inserting a liner into a metallic pipeline is disclosed.  The liner is formed from a plurality of concentric tubes that are enveloped in a flexible, expansible, tear resistant material.  When the concentric tubes are pulled into the pipeline, the tear resistant material provides protection against tearing of the tubes by burrs, snags or other imperfections on the inside of the metallic pipeline.  The tear resistant material may be a fabric, woven material or mesh. Materials having a structure that permits escape of fluid entrapped during subsequent expansion of the concentric tubes on formation of the liner are preferred.  The method permits the lining of pipeline sections that have bends, loops or the like, while protecting the liner from tearing during insertion into the pipeline.

Abstract: ABSTRACT IMPROVED ELECTRICAL EJECT HEADER:     An eject header comprises an elongate insulative housing  having  opposing  longitudinally  extending sidewalls and transversely extending endwalls and a base supporting a plurality of male terminal posts therein for electrical connection with socket contacts of a complementary connector.  The sidewalls, endwalls and  base  define  a  cavity  for  receipt  of  such complimentary socket connector.  A pair of ejectors are mounted on the housing for pivotal movement in a plane substantially parallel to the endwalls and wherein the ejector lever is manually moveable toward and away from one of the sidewalls.  The sidewall is formed to have an opening for receipt of a foot portion therethrough into the header cavity.   Further,  the sidewall is formed to have a sidewall portion attached to the endwall such that the sidewall portion intersects the plane of pivotal movement of the ejector lever.  The attached sidewall portion,  in addition to providing structural strength through the header housing, serves as a stopping surface for movement of the eject lever. By using the sidewall portion as a stop surface, the throw distance for ejecting the complementary socket connector is enhanced.

Patent CA-2053724-A1 (CA)
Inventor: COCITO GIUSEPPE
IPC: G01J9/04
Filed: 1991-10-18
Abstract: A system for measuring the refractive index profile of optical components using a monochromatic radiation source and an acousto-optical modulator, which is driven by a periodically varying frequency. The modulator emits a first beam having the same wavelength as the source, and a second beam whose wavelength and emission direction vary with the modulating frequency. After the second beam has been collimated, radiation from both beams is directed towards a component under test and an electrical signal having varying frequency is generated representing of the beat between radiation from the two beams exiting from the component. A spectral analysis of the beat signal is performed, the refractive index value being derived from the position taken by the various frequencies of the beat signal on a detection plane.

Title: Process for the production of foamed polymer particles
Inventor: KUWABARA HIDEKI
IPC: C08J9/12
Filed: 1991-11-13
Abstract: Abstract of Disclosure Disclosed herein is a production process of foamed polymer particles, wherein particles of a polymer, which contain a silica-alumina adsorbent in which the molar ratio of SiO2/A1203 is at least 1.15, are dispersed in a dispersion medium in the presence of carbon dioxide in a closed vessel, the resultant dispersion is heated to a temperature not lower than the softening temperature of the polymer to impregnate the polymer particles with carbon dioxide, and the polymer particles and the dispersion medium are then released into an atmosphere of a pressure lower than the internal pressure of the vessel, thereby expanding the polymer particles.  The polymer may be an uncrosslinked propylene polymer, uncrosslinked, linear low-density polyethylene or crosslinked polymer.

Patent CA-2060237-A1 (CA)
Inventor: CLOONAN THOMAS J
IPC: H04B10/27
Filed: 1992-01-29
Abstract: A network arrangement and control method where, before any transmission of data occurs for a particular communication, a network controller determines an unused path to provide a connection, advantageously all the way through the network from a given inlet to a given outlet. Once the identity of the unused path is known, the controller determines control information for use in activating that path and transmits that control information into the network, significantly via the network inlets. The network responds by activating the determined path and communication is enabled via the activated path, but only for the single connection and no buffering of information is required within the network. The network is particularly well suited for optical implementation and control is effected without the use of spatial light modulators but rather by means of control elements embedded within the network itself.

Abstract: Film-based composite structures meet the requirements of highly weight-efficient SDI space-based systems. These structures are rigid, lightweight, dimensionally stable, and possess a high degree of structural damping. Thin-walled structures (wall thickness less than 50 µ) made from self-reinforced ordered-polymer films overcome drawbacks of fiber-reinforced composites, and provide resistance to microcracking, ply delamination and impact. They have high temperature capability (over 300 ·C), low temperature (cryogenic) capability and the capability for hardening and survivability. The modulus and dimensional stability of film-based ultralightweight honeycomb sandwich structures is better than currently possible with aluminum or fiber-reinforced composite materials.  Other thin-walled structures such as tension web beams and thin facesheets also show similar stiffness-to-weight advantages over current materials.

Abstract: The present invention defines a biological role for the following sequence of amino acids that is found in the nucleocapsid domain of the gag precursor polyproteins of all replication-competent retroviruses: -Cys-X-X-Cys-X-X-X-X-His-X-X-X-X-Cys-, wherein X represents variable amino acids. The invariant residues constitute part of a vital protein structure, at least one of which are found in all retroviruses and which are involved in the selection and packaging of genomic viral RNA into infectious virus particles. Disruption of this structure leads to the formation of virus-like particles which appear to be structurally normal, but which do not contain the normal complement of viral RNA. Therefore, their infectivity is drastically reduced or completely eliminated. The infectivity of any retrovirus, including human retroviruses, and more particularly human immunodeficiency virus (HIV), can be drastically reduced or completely eliminated by generating mutants that lack some or all of the invariant residues required to form the structure. In addition, any means of disrupting the functions of this array will in turn disrupt the viral life cycle. Thus, with the knowledge provided by this invention, chemotherapeutic reagents aimed toward this array may be devised.
