Title: Optical fiber laying structure for electric power cable line trouble occurrence location detecting system
Inventor: AMANO KAZUO
IPC: G01R31/08
Filed: 1991-07-10
Abstract: In an optical fiber laying structure for an electric power cable line trouble occurrence location detecting system for detecting a trouble occurrence location by laying an optical fiber along an electric power cable line, the portion of the optical fiber laid along the cable of one of the two adjacent sections is superposed on the portion of the optical fiber laid along the cable of the other sections in an area in the vicinity of the boundary of the electric power cable line.  Thus, if a temperature rise occurs due to a trouble such as a ground-fault in the boundary area, the temperature peak position, i.e., the trouble occurrence location can be detected by the two different optical fibers.  Therefore, the trouble occurrence location in the boundary area can be accurately detected.

Title: Method of producing silanes from silicon monoxide
Inventor: BOKERMAN GARY N
IPC: C01B33/04
Filed: 1991-08-06
Abstract: SILANE PRODUCTS FROM REACTION OF SILICON MONOXIDE             WITH ORGANIC HALIDES                         ABSTRACT           The present invention is a process for preparing silanes from the reaction of solid silicon monoxide with organic halides.  The solid silicon monoxide is reacted with the organic halide in the presence of a catalyst which can increase the conversion of silicon monoxide to silanes and partially select for the type of silanes produced.  The process may employ an activation step in which the solid silicon monoxide is activated by heating in an inert atmosphere.  Activation of the silicon monoxide can increase silicon conversion and alter the type of silanes produced.

A pulling eye extends from the second end of the body portion to permit installation and removal of the fitting from the surface of the access.    A  coupling on  the  exterior  side  surface connected  to  the  passage  permits  the  insertion  or removal of a media from the component or the venting of gases contained therein.
Patent CA-2053245-A1 (CA)
Inventor: EDWARDS JEFFREY C
IPC: E21B49/08
Filed: 1990-04-20
Abstract: Following completion of the testing procedure applied to a newly drilled oil well using a mechanism of the annulus pressure-responsive type, it is necessary safely to "shut down" the test tools, and then to remove the test string from the packer assembly and pull it to the surface. It is desirable for the high pressure reference gas in the tool to be vented before the string reaches the well head. It is also an advantage if there be incorporated within the test string some means of isolating the upper portion of the tubing thereof, and of subsequently providing a route for communication between this tubing and the annulus, so that tubing-contained well liquid above the test string can then be circulated out of the tubing before it is raised to the surface. The invention provides apparatus for the venting and isolation procedures just described, this apparatus permitting those operations to be carried out as an automatic sequence, following the application of a single actuating pressure pulse to the annulus. For the venting of the reference gas, the invention suggests pressure release apparatus having two spaced pistons (7, 11) located at opposite ends of a chamber (10) filled with that gas and blocking both a gas vent (17) to annulus and a hydraulic liquid passageway (22: to further up the test string), the pistons being held together by a shear pin (13) until the application of a predetermined pressure (higher than the gas reference pressure) at the outside ends of those pistons causes the pin to shear, allowing sequential movement of the two pistons towards each other, with the effect of firstly opening the gas vent to annulus, and secondly opening the passageway (22) to a chamber (24) of hydraulic liquid. The hydraulic liquid pressure within this passageway then causes actuation of ball valve apparatus for isolating the upper section of tubing. This apparatus is in the form of a ball-valve-driving piston (39) blocking another passageway (40) for hydraulic liquid, which piston is: forced to move under the influence of the pressure, breaking a restraining shear pin (44) as it does so, and closing the ball valve while opening this other hydraulic liquid passageway, permitting transfer of hydraulic pressure to apparatus for venting the contents of the tubing to annulus. Finally, this venting apparatus contains a longitudinally-movable sleeve member (54) the position of which determines whether or not flow is permitted, via vent ports (55, 56), from the test string tubing to the annulus.

Abstract: TITLE FLUID DISTRIBUTION SYSTEM HAVING    NOISE REDUCTION MECHANISM                ABSTRACT OF THE DISCLOSURE A fluid distribution system, such as a valve, comprises a housing having a chamber which has a plurality of acoustic modes.  The acoustic modes are excited when fluid flows through the chamber.  An inlet passage and an outlet passage are disposed in fluid communication with the chamber.  A plate is disposed in the inlet passage.  A plurality of orifices are formed in the plate.  The orifices conduct fluid from the inlet passage to the chamber and reduce the coupling between the flow of fluid through the inlet passage and the acoustic modes of the chamber.  With this arrangement, the acoustic modes of the chamber and the resonance frequency of each of the orifices are substantially unexcited by the flow of fluid through the orifices.

Abstract: PORTABLE SUPPORT SYSTEM FOR SUSPENDING PERSONS FROM BUILDINGS                  ABSTRACT OF THE DISCLOSURE         A portable support system for use on the roof of a building to support an object and/or person therefrom.  The system is arranged to be readily rolled to a desired position adjacent the edge of the roof and includes two wheeled frame assemblies and a collapsible/extendable boom assembly.   The boom assembly comprising pivotable sections arranged to be extended  from  a  compact  orientation  to  an  extended orientation  and  vice  versa.    The  frame  assemblies  are arranged for connection to respective portions of the boom assembly.    When  the  boom  assembly  is  in the  compact orientation  the  frame  assemblies  are  closely  connected together via plural  connecting members to form a compact cart.   The frame assemblies each include a pair of spaced wheels which can pivot in any direction to enable the cart to be readily wheeled to a position at the edge of the roof. The  frame  assemblies  are  then  disconnected  from  the connecting members,  and the boom sections extended so that the frame assemblies are spaced further apart for stability. A portion of the boom assembly extends over the edge of the roof to support a person/ object therefrom.  When the system is in position supporting the person/object the wheels are locked into an orientation so that they may only roll in directions transverse to the axis of the extended boom so that the system may roll along the edge of the roof,  if desired.

Title: Lysozyme dimers and method of preparing them
Inventor: HERRMANN PETER
IPC: A61P29/00
Filed: 1990-01-08
Abstract: A method is provided for preparing a highly-purified lysozyme dimer product, which comprises dimerizing lysozyme monomer with a suberimidate coupling reagent in a buffer solution adjusted to pH 10, stopping the dimerization at a given point by lowering the pH to 7 via addition of HCl or other suitable acid solution, and purifying the dimeric lysozyme by a series of elution steps carried out using liquid chromatography. Monomeric lysozyme remaining undimerized by the initial dimerization step is recycled into the process in order to increase yield. The present system is advantageous in that large amounts of purified lysozyme dimer can be prepared efficiently and relatively inexpensively, and the lysozyme dimer so produced is useful in treating viral and/or bacterial diseases without causing the cytotoxic effects associated with the lysozyme monomer.
