Abstract: An inflatable packer apparatus for use in a well bore has pre-formed metal stress rings surrounding the respective opposite end portions of the packer element. The stress rings are machined to initially have conical outer surfaces, and then are outwardly stressed beyond their yield strengths to obtain plastic deformation such that such outer surfaces are generally cylindrical so that the packer element can be inflated to higher pressures.

Abstract: A variable capacity vane compressor has an axial pressure device for applying variable axial pressure to a rotary valve.  The rotary valve plate locates in a rotary valve housing and changes the capacity of the compressor due to its rotary position.   An actuator member rotates the rotary valve plate in response to varying pressure in the discharge and intake chambers. A control valve supplies a variable control pressure to the actuating member for moving the actuating member to rotate the rotary valve plate.  An annular axial pressure chamber is located between the rotary valve housing and the rotary valve plate.  A control pressure port leads from the control valve to the axial pressure chamber.  A seal member within the axial pressure chamber applies an axial force on a bearing located on the rotary valve plate.    The  control  valve  which  supplies  variable pressure used to vary the actuator member position also supplies the control pressure to the axial pressure chamber.

Granted: 2000-10-17
Abstract: A method of manufacturing grounding connectors (1) based on a stamping process on progressive tooling which can produce a grounding connector (1) which is lighter, of a reduced size, and is of low manufacturing cost. The wedge type grounding connector (1) comprises a hollow body (2), a wedge (3), a shear-head bolt (4), two nests (5, 6) for grounding cables (7) and rods (8), and a solid fixture block (9). With the exception of the fixture block (9), all components of the grounding connector (1) are light, and of a reduced size since these components of the grounding connector (1) are manufactured by a stamping process.

Abstract: A necktie with a knot-forming core is disclosed, which is composed of a necktie-body made of cloth and a knot-forming core made of synthetic resin. The necktie body comprises (1) a necktie panel having a combining hole at its top, (2) a knot-cloth being sewed to the knot-forming position of the necktie panel and having a pair of combining holes at its two lower corners, (3) and a pair of necktie-arms being sewed to the respective upper corners of the knot-cloth and being used for jointing the necktie to shirts or blouses. The knot-forming core comprises (1) a core-body and (2) a combining projection provided on the back of the core-body. A Y-shaped necktie having a desired size and shape is assembled merely by placing the core on the back of the knot-forming position of the necktie-body, and thereafter fitting orderly the above-mentioned three combining holes around the combining projection of the core. The merit of this invention is that the Y-shaped necktie thus assembled is maintainable, disassemblable, and re-assemblable. And the so made Y-shaped necktie is to be put on or taken off simply by applying such jointing means as (1) a jointing tool like a Velcro (trademark) - tape, hook, press studs, or magnets, attached both at the necktie-arms and the shirt, (2) a band detachably connected to one of the necktie-arms and which applies the above mentioned jointing tools both at its other end and the counterpart necktie-arm, (3) a string movably penetrating through the core, and whose length is adjustable simply by pressing or releasing the projection on the back of the core.

Abstract: A dual completion for gas wells includes a dual base with a primary hanger incorporated in the base. Primary and secondary coiled tubing strings extend through the base at a downwardly converging angle of 2° or less. The dual base is mounted on an annular blowout preventer. At the top of the annular blowout preventer is a tubing centralizer that aligns the two tubing strings parallel to one another. The blowout preventer has two side ports below the bladder allowing the operator to produce gas from the annulus, to flare gas to atmosphere or to pump in kill fluid in the event of an emergency. The alignment of the tubing strings allows production recorders to be run in either string.

Abstract: Automatic Hazard signal alarm deals with and warns of the lack of stability and balance of the automobile at the time of the instant stops in the application of the brakes. It warns of the lack of stability and balance at the time of slipping during fast turns as well as on uneven or steep downhill roads. It also gives sufficient advanced warning to the other vehicles in the proximity of the automobile having such a system.  The system contains four cylinders, each of which works with a magnetic piston. Each magnetic piston could move in the direction of the cylinder whereby the magnetic switches as sensors situated at one end of each cylinder activate the system by the effect of the magnetic pistons. A spring in each cylinder determines the limit of the movement of each piston and a regulating screw which is situated on the other end of each cylinder regulates the movement and adjusts the initial location of the pistons by the connected spring. This mechanism sets up the sensitivity of the system.

Title: Pressure-boost device for downhole tools
Inventor: MYHRE MORTEN
IPC: E21B23/04
Filed: 1996-08-08
Granted: 2006-04-04
Abstract: A pressure-boosting apparatus particularly amenable for use in downhole applications is disclosed. The pressure-boosting apparatus employs an unbalanced piston which is initially fixated in a run-in position. The piston has a flowpath therethrough in which is mounted a check valve. Initially, pressure is applied to above and below the piston which results in an unbalanced force on the piston due to its configuration. Flow to the tool initiates its actuation at this time.  When the unbalanced force reaches a predetermined level, the piston is no longer fixated to the housing and begins to accelerate. Acceleration of the piston closes the check valve due to the sudden decrease in pressure behind the check valve and an increase in pressure in front of the check valve as the fluid volume in front of the piston is compressed. Due to the proportional relationship between pressure and area, a magnification of force originally delivered by the pump is achieved for completion of the setting of a downhole tool such as a packer or bridge plug or the like.

Title: Laminated bows
Inventor: FASCIO CARLO
IPC: D04D7/10
Filed: 1996-09-26
Granted: 2001-02-06
Abstract: The present invention relates to decorative bows formed from a folded pattern of a laminated substrate. The substrate comprises one or more layers of printed material laminated between two layers of laminate film so that the print is visible on both sides of the substrate. In order to match the bow to gift wrap the substrate can be formed from gift wrap paper with a protective film laminated to the printed side of the paper. As gift wrap is normally only printed on one side, two sheets of gift wrap are laminated with their unprinted sides together resulting in a substrate having printed material on both sides with a protective film on each side. The gift wrap can be substituted with cardboard, fabric, vinyl, plastic or other film. By laminating the material the resulting bows are waterproof, durable, reusable.
