Abstract: L'invention concerne une soupape de sécurité comprenant un corps (4) de soupape définissant une chambre (6) de soupape. Un tube intérieur (8) traverse ledit corps (4) d'un orifice d'entrée (9) à un orifice de sortie (10). Un joint étanche est placé dans un tube intérieur (8) à proximité de l'orifice d'entrée (9). Le produit liquide pénètre dans ladite chambre (6) par la première série de trous (16). Une troisième série de trous (20), placée à proximité de l'extrémité de sortie, permet au produit liquide de quitter la chambre (6) de soupape. La troisième série de trous (20) présente une zone d'écoulement plus petite que celle de la première série de trous (16). La chambre (6) de soupape se remplit ainsi de produit liquide, un flotteur placé autour du tube intérieur commençant à s'élever, laissant apparaître une seconde série de trous (18) dans ledit tube intérieur. La zone d'écoulement de la seconde série de trous (18) est sensiblement équivalente à celle de la première série de trous (16). Le flotteur se déplace entre une position à plein débit dans laquelle les seconde (18) et troisième (20) séries de trous sont découvertes et une position à débit réduit dans laquelle seule la troisième série de trous apparaît.

IPC: H01H11/00
Filed: 2000-06-28
Abstract: A closed loop feedback system controls electrical switchgear that moves at least one contact relative to another contact to switch power on and off in an AC electrical circuit. The control system includes a position feedback device that is operatively coupled to at least one of the two contacts to produce contact position information. A processor receives and analyzes the contact position information to control contact motion to provide AC waveform synchronized switching. The electrical switchgear may be a capacitor switch that includes a bi-stable over-toggle latching device. The latching device maintains the contact in one of an open stable position in which electrical current does not flow through the contacts or a closed stable position in which electrical current flows through the contacts.

Title: Structure for holding optical fiber
Inventor: IMAMURA KAZUO
IPC: G02B6/36
Filed: 2000-08-03
Abstract: A thin member for sealing and holding optical fibers laid two-dimensionally is composed of a base member layer, an adhesive member layer deposited on the base member layer, and a laminate member layer holding the optical fibers between it and the adhesive member layer. The optical fibers are arranged parallel not to be superposed on one another. They are bent individually by 180 degrees at the right-hand end of the thin member, bent downward toward the lower side of the thin member at the area from the central part to the left-hand side part, and led out of the thin member. Hence the structure is thin and therefore can be accommodated in a small space, enabling a small size. If the portions, led out of the thin member, of the optical fibers are covered with tubes, breakage of the optical fibers can be prevented. The thin member can be flexible.

Title: Bearing socket liner for ball joint
Inventor: MAUGHAN GARTH B
IPC: F16C11/06
Filed: 2002-06-20
Abstract: An improved socket liner for a ball and socket joint is adapted to be fixedly installed within a joint housing so as to encase the ball. The housing defines a longitudinal axis, and the liner, formed in two longitudinally extending mating halves that confront one another along surfaces parallel to the axis of the housing, are oriented to provide a theoretically tightest possible ball bearing-socket fit. Each liner half includes at least one protuberance on each longitudinally confronting surface. The protuberances not only facilitate location of the liner halves during assembly, but also assure a physical separation between the halves, creating an additional lubrication groove for enhanced operation of the joint during its useful life. In one preferred form, a compliant thin soft material cover is overmolded over the exterior socket liner structure, and exterior surface slots integrally provided on the cover interlock with protruding ribs: fixed to the interior of the housing.

Abstract: Improved methods and apparatus for completing a subterranean zone penetrated by a wellbore are provided. The improved methods basically comprise the steps of placing a sand control screen (e. g., screens, screened pipes, perforated liners, prepacked screens, etc.) and an outer shroud assembly mounted over the sand screen in the wellbore adjacent the zone to be completed, the shroud having perforated and blank (non-perforated) segments with the blank segments corresponding to selected intervals of the wellbore, for example problem zones such as shale streaks or isolated zones where flows are restricted by mechanical seals or packers, and injecting particulate material into the wellbore, whereby gravel packing takes place in the remaining length of the wellbore/shroud annulus without voids. The inner annulus between the shroud and screen provides an alternate flow path for the slurry to bypass the blocked intervals and continue with its placement.      Mechanical seals or packers may be used in combination with the shroud and associated sand screen. The method is also applicable to placing gravel packs in a cased and perforated well drilled in the zone.

Title: Method of assembling pipe joints
Inventor: ASHBY CHARLES L
IPC: G01M99/00
Filed: 2001-01-02
Abstract: A method of assembling pipe joints in a pipe string allows the circumferential orientation of a first pipe (13) in the pipe string to be determined relative to a second pipe (13) in the pipe string. Each pipe joint has a coupling member (15) and at least one pin member (13), the pin member (13) being threadingly connected to the coupling member (15) to create the pipe joint (11).  Threads (21, 29) are created for the pin member (13) and the coupling member (15) of each joint, and each pin member and coupling member is marked with an alignment mark (35, 37). The threads (21) for each pin member are created so that they are identical to the threads on the other pin members in the pipe string. This is done by gaging the overall rotational capacity of each pin member with a coupling marking gage (43) and adjusting a thread depth as needed.
