Title: Logging system for measuring dielectric properties of fluids in a cased well
Inventor: SINCLAIR PAUL L
IPC: G01N22/00
Filed: 1994-02-25
Abstract: ABSTRACT OF THE DISCLOSURE    An improved system for measuring dielectric properties of fluids in an oil well, utilizing the well casing as a waveguide for certain electromagnetic signals.   A production logging tool in accordance  with the  invention  includes  a  cylindrical  mandrel sheathed by a housing.   Transmitting and receiving coils are contained in annular grooves defined in the mandrel.  In operation, the tool is suspended by a wireline logging cable within the casing of a producing well.   The transmitting coils generate magnetic fields and azimuthal electric fields, which induce voltages in the receiving coils.  These voltages are affected by the dielectric properties of fluids in the casing,  and the voltages may be interpreted to determine  dielectric properties  such as  water resistivity, dielectric permittivity, water hold-up, water cut, and water salinity.   Due to specifically sized longitudinal mini-waveguides defined in annular regions about the circumference of the housing, the magnetic and azimuthal electric fields resulting from the transmitting coil may be sensed by the receiving coils, but the voltage-induced electric fields created by the transmitting coil are prevented from interfering with the receiving coils.          Accuracy of the invention may be enhanced by using a second transmitting coil,  by spacing the coils according to specific guidelines,  by operating the transmitting coils between lower-cutoff and upper cutoff frequencies, and by using fluid mixers.

Title: Programming response to electronically-controlled gauges
Inventor: DANNENBERG ROBERT D
IPC: G01R7/06
Filed: 1994-03-21
Abstract: Rather than using the viscosity of dampening oil to establish the speed at which the movement of an air care instrument gauge moves, the speed is defined by programming speed data into memory of a microprocessor that controls the movement. When the microprocessor receives an input signal commanding the movement to move, it develops an output signal for operating the movement that is based both on the input signal and on the stored speed signal. The stored speed signal is used by the microprocessor as weight for a software filter used in development of the output signal.

Title: P53as protein and antibody therefor
Inventor: KULESZ-MARTIN MOLLY F
IPC: C12P21/02
Filed: 1995-06-05
Abstract: The invention comprises plasmids and viral vectors containing an animal p53as cDNA sequence. A portion of the p53as sequence may be identified to a position of wild type p53 gene from the same animal. In preferred embodiments, the p53as is mouse or human p53as. A preferred viral vector is baculovirus vector. The invention further includes antibodies both polyclonal and monoclonal, to p53as and to at least a portion of human p53 intron 10 sequence encoding SLRPFKALVREKGHRPSSHSC which is related to p53as sequences and plasmids and viral vectors containing such sequences. All of the above find utility in studying p53 and p53as and their relative expressions which is believed important for detection and control of malignant cells and their susceptibility to treatment agents. The antibodies can detect the presence of p53as and related sequences and when injected into cells could cause cell cycle arrest and the plasmids and viral vectors, with appropriate promotors, can cause expression of the p53as and p53 intron 10 sequences which can affect cell growth and perhaps arrest certain malignancies.
