Abstract: An apparatus for radially expanding tubular members.

Abstract: An apparatus and method for forming a wellbore casing. An annular piston is displaced in the axial direction by pressurizing an annular piston chamber. The axial displacement of the piston radially expands a tubular member into contact with a preexisting tubular member. The radially expanded liner hanger is then decoupled from the apparatus.

Abstract: A mechanical human figure standing in a golf putting posture, having a lower stationary assembly of feet, legs, and spine, and having an upper pivoting assembly of shoulders and arms. The arms are fixed relative to the shoulders. A golf club is fixed to the lower ends of the arms in a golf putting grip. The upper assembly is attached to the spine on a pivot axle extending forward and upward from the top of the spine between the shoulders. The club head pivots in a circular swing arc tangent to the ground. A golf ball and a stroke guide are placed on the ground in front of the robot. Two laser sources on the pivoting assembly illuminate two aspects of a proper stroke on the ground and on the guide. The arms are lifted manually into a backswing and released, striking the ball and demonstrating the guide.

Abstract: A golf putting guide that is placed on the ground between a golfer and a golf ball. It has a vertical front surface facing the ball that is part of the elliptical vertical projection of a desired swing circle of the club head. The heel of the club head slides along the front surface of the guide in putting practice, guiding the club head in a planar swing circle that is centered between the golfer's shoulders. The top surface of the guide is marked with a series of club face alignment lines extending backward from the top front edge of the guide. Each of these lines is perpendicular to a line tangent to the elliptical top front edge of the guide. These lines visually guide the alignment of the club head as it moves along the front surface of the guide so the club rotates only on a single axis.

Abstract: A wellbore casing formed by extruding a tubular liner off of a mandrel. The tubular liner and mandrel are positioned within a new section of a wellbore with the tubular liner in an overlapping relationship with an existing casing. A hardenable fluidic material is injected into the new section of the wellbore below the level of the mandrel and into the annular region between the tubular liner and the new section of the wellbore. The inner and outer regions of the tubular liner are then fluidicly isolated. A non hardenable fluidic material is then injected into a portion of an interior region of the tubular liner to pressurize the portion of the interior region of the tubular liner below the mandrel. The tubular liner is then extruded off of the mandrel.

Abstract: Disclosed is a process for preparing a fibrous web. The fibrous web includes a microencapsulated material, such as a microencapsulated phase change material, adhered to the web. Preferably, the web is prepared in a melt-blowing or spun-bonding process. In the melt-blowing process, cooling water containing the microcapsules is used to cool melt blown fibers prior to collection on a collector. In the spun-bonding process, microcapsules are applied in liquid suspension or in dry form to a heated web, for instance, after the web has been calendared. The fibrous webs thus prepared have numerous uses, and are particularly suited to the manufacture of clothing.

Abstract: An expansion mandrel includes a lubrication system for lubricating the trailing edge portion of the interface between the expansion mandrel and a tubular member during the radial expansion of the tubular member.

Abstract: A liquid crystal display device is described in which the TFTs are located directly below the spaces between pixels. The black matrix comprises an array of opaque conductive elements with one such element being above each TFT. The black matrix is incorporated into the TFT structure. By using highly conductive material for the black matrix elements their thickness is held to a minimum, thereby minimizing their impact on planarity. Optionally, this highly conductive layer may be laminated with layers of a non-reflective conductor that makes good ohmic contact to silicon. In one embodiment, metal filled via holes are added that connect the TFTs to the transparent conductive pixel control elements by way of the black matrix layer. In another embodiment, the black matrix layer is connected to be in parallel with the gate electrode, thereby reducing the series resistance of the latter. A process for manufacturing the display is also described.

Abstract: A redundant communication system contains a principal transceiver and a back-up transceiver to be controllably substituted for the principal transceiver. A monitor protection switch, which controls swapping the two transceivers, has an RF loopback test circuit that is switchably coupled to whichever transceiver is the backup. The RF loopback test circuit monitors the operational capability of the back-up transceiver, and provides an indication of its functionality. If the back-up transceiver is defective, corrective action can be taken in advance of a potential operational failure of the principal transceiver. As long as the RF loopback test circuit indicates proper operational capability of the back-up transceiver, the redundant transceiver can be immediately switched in place of the principal transceiver.

Abstract: An apparatus for coupling a tubular member to a preexisting structure.

Abstract: An RF loopback test circuit is adapted to be coupled to an antenna port of a digital radio, to determine whether the radio is functioning properly. A frequency generator outputs an auxiliary frequency corresponding to the sum or difference between the radio's transmit and receive frequencies. The auxiliary frequency is coupled to a Schottky diode mixer, which is also coupled to the input/output port. If the radio's transceiver section is operating properly, the sum or difference frequency output of the Schottky diode mixer will be passed by only the diplexer's narrowband receive path filter to the radio's receiver section. The mixer's sum frequency is blocked by the diplexer's narrowband filters. Therefore, if the receiver section provides an indication that it is receiving a sufficient signal level from the RF loopback test circuit, it can also be inferred that each of the transmitter and receiver sections is operating properly.

Abstract: The fuel filter assembly for filtering and removing water from a fuel under pressure includes an outerhousing, an inner sleeve member, an annular space between the outerhousing and the inner sleeve member, and filtering means for filtering the fuel. The filtering means is positioned within the sleeve member. The fuel inlet is at the upper end of the outer housing and provides fluid flow between the outer housing and the inner sleeve. The fuel inlet and annular space are positioned and dimensioned to provide a downward, non-circumferential, substantially laminar flow in the annular space. The inner sleeve member extends downwardly to a position below the bottom of the filtering means. The downwardly flowing fuel and contaminants must turn 180 degrees and flow upward through the filter media to the outlet. The slow moving denser components settle out in the accumulation chamber. The accumulation chamber is the region within the lower end of the outerhousing, below the filter media and the annular sleeve.

Abstract: A spread spectrum communication system for wirelessly transporting autonomously time-referenced telecommunication data couples the data streams to mutually synchronized multiplexers, outputs of which are encoded and applied to associated I and Q channel spreaders, which spread the respective multiplexed data streams using mutually orthogonal spreading code sequences. The resulting spread I-channel data streams are coupled to I and Q channel summing units outputs of which are applied to respective channels of a QPSK modulator and transmitted to a receiver site. At the receiver the QPSK signals are correlated in despreading correlators and then decoded and demultiplexed to produce data streams, corresponding to those applied to the transmitter.

Abstract: An improved method and apparatus for imparting a smooth surface to gypsum fiber panels. The method involves imparting energy to the surface of a slurry as the slurry is dewatered just prior to rehydration. The apparatus used to impart the energy is a water spray including a source of pressurized water such as a pump, a distribution manifold and a plurality of nozzles to direct the water spray at the surface of the slurry. In operation, the water spray is directed against the surface of the slurry. The flow disrupts the slurry to a fraction of its total depth, thus dispersing clumps or flocs of commingled crystals and fibers in the depth that would give the surface of the finished panel a rough surface if they were allowed to remain.
