Title: Methods and devices for real-time formation imaging through measurement-while-drilling telemetry
Inventor: MONTARON BERNARD
IPC: G01V3/34
Filed: 1995-05-25
Abstract: Methods for providing an image at the surface of a formation surrounding a borehole in real-time include associating resistivity measurements with a predetermined number of preselected toolface positions.  The resistivity measurements are subjected to data compression and transmitted uphole by MWD telemetry.   At the surface, the compressed resistivity measurements are associated with the preselected toolface positions and with a calculated translational distance value.  The resistivity measurements are decompressed and/or converted to pixel information.  The pixel information is arranged according to toolface position and translational distance to create a high resolution of the formation.  These processes are repeated over time so that the image created represents the formation over a selected distance.  Apparatus of the invention used to perform the methods include an MWD telemetry device, at least one downhole formation resistivity sensor, and downhole device(s) for determining the toolface of the resistivity sensor.  Downhole processor(s) are provided for synchronizing, selecting and compressing resistivity measurements.  On the surface, a translational distance sensor is provided along with processor(s) for associating, converting, and arranging.  At the surface, the associated information is used to form an image of the formation spanning a number of translational distance values.

Abstract: There is provide a method for optical telecommunications with which an optical signal modulated for the plane of polarization can be received for certain without lowering the threshold level and being affected by noises so that any optical telecommunications can be identified without fail. With the method, an optical signal is modulated by continuous pulses a at the transmitting side before transmission and a predetermined number (n) of pulses a are extracted within a given period of time in synchronism at the receiving side so that the presence of a modulated optical signal is acknowledged only when the number of pulses a received within the given period of time is smaller than the predetermined number (n) but greater than another predetermined number (m) (n  m). This method may be so modified that the absence of a modulated optical signal is acknowledged even when the above defined numberof pulses are received if k or more than k (k  1) noise signals b are found between any successive two of the received pulses.

IPC: G01N9/00
Filed: 1990-05-23
Abstract: Apparatus and accompany-ing methods for use therein for a Coriolis mass flow rate meter (5) which is substantially immune to noise, and more particularly, to such a meter that is substantially unaffected by noise that occurs at substantially any frequency differ-ent from a fundamental frequency at which the flow tube(s) (130, 130') in the meter vibrates. Specifically, the meter (5) relies on measuring mass flow rule by determining the phase difference that occurs be-tween real and imaginary compo-nents or the discrete fourier trans-form (DFT) or both the left and right velocity sensor waveforms evaluated at the fundamental fre-quency at which the flow tubes vi-brate. The fundamental frequency is located, during an initialization operation, by providing a power spectrum, determined through use of the DFT, of one of the sensor signals and then selecting that frequency at which the magnitude of the power spec-trum reaches a maximum value. In addition, the frequency at which both velocity sensor signals are sampled is readjusted in re-sponse to any change in the phase of one of the velocity sensor signals, as transformed using the DFT, in order to assure that the sampling frequency always remains substantially equal to a pre-defined integer multiple or the fundamental frequency. Further-more, the meter, through use of the numerical value of any such phase change, also provides a density indication which is also substantially immune to such noise.

Title: Continuous plastics molding process and apparatus
Inventor: KEMERER W JAMES
IPC: B29C33/36
Filed: 1991-01-17
Abstract: A  continuous  process  and  apparatus  for  forming products  from thermoplastic materials  between top  and bottom mold carriages is disclosed.  Each carriage has a frame  including  a  backup  plate  coated  with  a  low coefficient  of  friction material  over which  slides  a continuously moving belt mold.  The belt mold is comprised of a flexible silicone rubber mold adhered to a fiber belt.          The silicone rubber mold has a surface of desired shape for mating with an opposed mold surface to form a continuously moving  mold  channel  into  which  is  fed  thermoplastic material at a moldable temperature.  After molding the hot plastic material, localized surface heat of the belt molds is removed by cold air blown against the belt mold.  The low coefficient of friction backup plates have numerous air-bearing holes for feeding high pressure air between the low coefficient of friction plates and the moving fiber belt to reduce friction and reduce wear.  The fiber belts are guided and driven by a wide V-shaped central ridge or by twin-wide V-shaped ridges near their edges.   The V-shaped ridges fit into and mesh with corresponding geared teeth in grooves of the sprocket drive rolls and operate to maintain alignment of the mold belts.  An electric drive motor, with or without the assistance of a torque motor, drives both belt molds in unison to maintain their relative alignment.  Electric screw jacks raise the top carriage, extend and retract the grooved exit rolls, and fine tune the alignment of the moving belt molds by adjusting the grooved exit rolls and move the machine to and from the extruder.

Title: Heat exchanger utilizing grommets
Inventor: KOLB MICHAEL J
IPC: F28F9/14
Filed: 1996-01-19
Abstract: A heat exchanger utilizes resilient grommets to seal the tube to the header to prevent leakage. The grommet has a body portion extending around a portion of the tube within the header opening, a radially outwardly extending lip at one end of the body portion, and, when unstressed, a radially inwardly extending lip at the other end of the body portion which contacts the tube. The grommet body portion, when received within the header opening, remains substantially undistorted by the header. The fins are formed in a serpentine pattern such that, within the core body, the root of a bend is secured to a tube and the free end is cut at a root of a bend. The serpentine pattern near the tube ends is compressed to permit the tube ends to extend outward from the core body so that the free ends contact the grommet to limit insertion of the tube ends into the header openings. The header is initially sized such that, when welding the header flanges to the tank, the length of the header decreases so that the spacing of the header openings conforms to the spacing of the tube ends. The header flanges have a minimum height so that the strength of the connection between the flanges and the headercentral portion is unaffected by heat generated during welding.

IPC: G10L25/00
Filed: 1995-06-12
Abstract: With the signal encoding method and apparatus according to the present invention, noise components of plural channels are encoded individually by a first encoding unit 124, while noise components of plural channels are encoded in common by a second encoding unit 125.   A discriminating unit 123 discriminates characteristics of noise components of plural channels.  Based upon the results of discrimination, selective switching is made between an output of the first encoding unit 124 and an output of the second encoding unit 125.   If the noise components of plural channels are encoded in common, the compression ratio for the noise components of plural channels may be improved.  On the other hand, if the noise components of plural channels are not encoded in common, ill effects due to common handling can be prohibited.
