Granted: 2005-01-25
Abstract: A top drive is used to connect successive lengths of casing. The casing is gripped by a mechanism (100) which comprises a support (5) which is attached to the top drive by a drive plate (4). A circular plate (9) is rotatably mounted in the support (5) and is associated with four jaw assemblies (50). In use the mechanism (100) is lowered onto a length of casing until the circular plate (9) engages the top of the casing. When the top drive is rotated in one sense the support (5) rotates relative to the circular plate (9). This causes toothed cylinders (14) to rotate which, in turn, rotates eccentric members (12 and 13) which advance the jaws (15) into gripping engagement with the casing. Further rotation of the top drive rotates the casing and screws it into the casing below.

Title: Coriolis flowmeters using fibers and anisotropic material to control selected vibrational flowmeter characteristics
Inventor: VAN CLEVE CRAIG BRAINERD
IPC: G01F1/84
Filed: 1997-09-09
Granted: 2002-01-29
Abstract: A Coriolis flowmeter whose flow tubes are made, at least partly, of anisotrophic materials such as fiber reinforced composites. The composite material is formed by orienting the fibers in one direction to increase the tensile strength of the material in that direction. Selected areas of the flow tubes are formed of this composite to increase the flowmeter sensitivity and to separate desired flowmeter vibrational frequencies from undesired vibrational frequencies. Circumferentially oriented fibers increase the internal pressure containment capability of the flow tubes. A strain gauge affixed to the flow tubes flexes with flow tube deformation to indicate the internal flow tube pressure.

Title: Method and apparatus for obtaining transmit diversity using switched antennas
Inventor: TIEDEMANN EDWARD G JR
IPC: H04J13/18
Filed: 1998-11-30
Granted: 2006-11-28
Abstract: A method and apparatus for providing diversity transmissions to a receiving unit. A transmitting station used to communicate with the receiving unit may have a first and second antenna (34, 36) and repeatedly switch between the two antennas (34, 36) during the transmission of information to the receiving unit. Transmission of information may be initiated from a first antenna (34), and when terminated, transmission of information from a second antenna (36) is initiated. Likewise, after transmission of information from the second antenna (36) is terminated, transmission of information from the first anten na (34) continues. This "swapping" of antennas continues until the information transfer ends. Antenna swapping results in diversity transmissions that improve the ability of the receiving unit to receive a coded and interleaved information transmitted from the transmitting statio n. The interleaver may disperse the encoded symbols in each antenna dwell period such that decoder decisions are based on a mix of symbo ls from each antenna.

Granted: 2006-08-01
Abstract: The invention relates to a converter connection assembly with a direct voltage intermediate circuit (3) containing a transformer (8) with at least two windings (9 and 10). The transformer is connected in the intermediate circuit (3) in such a way that the undesired, asymmetric current components lead to a magnetization of the transformer core, and are thus suppressed. A grounded LC filter (Lf, Cf) is connected in front of the load (6). The filter effects a sinusoidal voltage on the load (6). As a result, the connection can be utilized with any polyphase machines and also during the expansion of existing systems.

Abstract: An improved electric clutch for driving refrigeration compressors and the like includes an annular ferromagnetic annular armature that is connected with a drive shaft via the outer peripheral portion of an annular resilient disk the inner peripheral portion of which is connected with a rotor that in turn is connected with the drive shaft. The armature is normally biased in the direction of the rotor toward an inactive de-energized position in spaced relation relative to an annular driven member that is connected with the driven shaft. A stationary electromagnetic coil is mounted on the opposite side of the driven member from the armature, so that when the coil is energized, the armature is attracted toward an active energized position in frictional engagement with the driven member, thereby to cause the driven shaft to be driven by the drive shaft.

Abstract: The quality of reconstructed speech on which background noise is superimposed is improved in a speech signal decoding apparatus for generating a speech signal by driving a filter, which is constituted by linear prediction coefficients, by an excitation signal. A smoothing circuit smoothes sound source gain in a noise segment using sound source gain that was obtained in the past. A smoothing-quantity limiting circuit calculates an amount of fluctuation on represented by diving, by the sound source gain, the absolute value of the difference between the sound source gain and the sound source gain that has been smoothed, and limits the value of the smoothed gain in such a manner that the amount of fluctuation will not exceed a certain threshold value.
