Patent CA-2005487-A1 (CA)
Title: Configuration with several splicing modules
Inventor: FINZEL LOTHAR
IPC: G02B6/36
Filed: 1989-12-14
Abstract: \                 ABSTRACT OF THE DISCLOSURE     A compact configuration of a large number of splicing modules that enables each splicing module to be freely accessible is made by connecting each splicing module to a carrier with a pivotal connection so that the pivoting axis extends through the interior of the splicing module parallel to the direction in which the light waveguide bundle is introduced into the splicing module.  The pivoting axes of several splicing modules extend parallel to one another.  Each splicing module has a hollow cylinder that is mounted to the carrier with U-sections.  Light waveguides are led through the hollow cylinders to each splicing module.  No excess length of the light waveguides is necessary since the hollow cylinders remain stationary during pivoting of a splicing module.  The pivotal connection of the splicing modules enables them to be "leafed through" like a book.  Each splicing module can be accessed in this manner so that the light waveguide splices located on it can be renewed or repaired.  The invention can be used in light waveguide splice coupling boxes.                                            :

Inventor: VAUGHEN JACK F
IPC: B60V1/18
Filed: 1990-06-20
Abstract: In an air cushion load transport vehicle, an annular sealing assembly comprising an annular inflatable hanger on the underside of a load-bearing base and an annular sealing means on the underside of the hanger confines a load-supporting air cushion that is continuously supplied with compressed air during operation, Stability is promoted by a number of design features in the inflatable hanger, the annular sealing means, the flexible connection between them and the load support structure. These include means for automatically closing off flow through hanger damping eyelets during initial hanger pressurization together with means to keep the eyelets open at all operating hanger heights. Additional covered ports are provided in the outer hanger wall positioned to automatically vent if the hanger is over-inflated thereby avoiding dyanmic instability.      A check valve is incorporated into the device to prevent damage from inadvertantly inflating the hanger before the cushion is pressurized. Finally, critical relation ships between key design parameters and seal materials are defined which avoid dynamic instability of the air cushion load-bearing vehicle during operation.

Abstract: ABSTRACT OF THE DISCLOSURE      An optical head is disclosed for detecting a tracking error on a recording medium by the reflected beam from the recording medium obtained by irradiating a beam on the recording medium.  The optical head splits a light path of the reflected beam into two light paths wherein a first photo detector arranged before the focal point of the re-flected beam in one light path having a light receiving area split into at least two parts detects the reflected beam in one light path, a second photo detector arranged beyond the focal point of the reflected light in the other light path having a light receiving area split into at least two parts detects the reflected beam in the other light path, and a control signal for tracking is generated by adding the out-put of the first photo detector to the output of the second photo detector.  In this control signal for tracking occurs no offset even when an objective lens moves in the diametric direction of the recording medium and shifts the light path of the reflected beam.

Title: Stripper rubbers for drilling heads
Inventor: BAILEY THOMAS F
IPC: E21B33/08
Filed: 1991-07-09
Abstract: ABSTRACT OF THE DISCLOSURE       A stripper rubber for use in a drilling head to seal against a work string deployable through the drilling head. The stripper rubber is longitudinally restrained to prevent extrusion of the stripper under pressure and to reduce the tensile and compressive stresses on the stripper rubber. One embodiment of the stripper rubber incorporates upper and lower metal  rings  which  are  maintained  in  spaced  apart relation by vertical rods thereby allowing radial expansion as  tool  joints  pass  through the  rubber  but  prevents inversion   of   the   stripper   rubber   under   pressure. Reinforcing cords added to the stripper rubber increase the longitudinal strength.  A second embodiment bonds a stripper rubber into a cylinder which restrains the rubber in the vertical direction.   Radial deflection is accommodated by allowing  the rubber to  flow vertically as  a tool  joint passes   therethrough.    Each  of  the  stripper  rubbers incorporates  an  integrally  formed  drive  bushing  which facilitates mounting within the drilling head.

Title: Process and apparatus for fabrication of silver coated high temperature ceramic superconductor fiber on metal substrate
Inventor: WOOLF LAWRENCE D
IPC: H01B13/00
Filed: 1991-08-20
Abstract: A method and apparatus for manufacturing a superconductor wire has a wire take-up spool and a feed speed control spool.      A wire substrate is taken from the feed speed control spool and onto the take-up spool as the wire take-up spool is rotated. The wire passes through a container which holds a diffusion barrier material, where the diffusion barrier material is electrophoretically deposited onto the wire substrate and subsequently sintered. The wire is also passed through a container which holds a superconductor material suspended in solution, and a layer of the superconductor material is electrophoretically deposited onto the diffusion barrier. The grains of the superconductor layer are then magnetically aligned and sintered. Also, a silver coating is electrophoretically deposited onto the superconductor layer and sintered. A diffusion bonding inhibitor material is then applied to the silver coating. Then, the silver-coated superconductor wire is spooled and heated to four hundred degrees centigrade (400°C) for one (1) day to oxidize the superconductor layer.
