Title: Multiple user digital receiver apparatus and method with combined multiple frequency channels
Inventor: KELLEY EDWIN A
IPC: H04B1/16
Filed: 1992-04-21
Granted: 1996-08-06
Abstract: A digital receiver apparatus and method, designed for multiple simultaneous users, digitizes a received analog RF signal and performs multiple frequency translations of the signal so that desired stations are grouped into a common frequency band separate from the remaining stations.  This frequency band is then isolated, and the individual select-ed stations are digitally separated, demodulated and audio processed to provide multiple simultaneous outputs.  The frequency translations are preferably performed initially on a time multiplexed basis.  Isolated station separation is performed either by time multiplexing, or by the use of multiple phase or tan lock loops.

Title: Process to increase petroleum recovery from petroleum reservoirs
Inventor: ELLINGSEN OLAV
IPC: E21B43/24
Filed: 1992-07-02
Granted: 1996-04-09
Abstract: This invention refers to a process as well as to the equipment required to enhance the recovery of petroleum from onshore and offshore reservoirs.   The pro-cess includes the simultaneous stimulation of the forma-tion by means of elastic sound waves, created by a sonic source installed at the oil well so that the elastic sonic waves which are superimposed reduce the adherence forces in the layer between oil/water and the rock forma-tion, and by means of the oscillating electrical stimula-tion of the same layer, as from the same wells subject to sonic treatment, where the electricity heats the formation by means of resistive heating, and thus increases the pressure, eliminating, thus, the surface tensions between the faces of the fluid as a consequence of the oscillatory action of the ions in the surfaces of the fluid and, in addition, reducing the viscosity of the fluids.   The pro-cess is achieved as the petroleum is produced in the wells thus treated, and the flow of petroleum acts then as a cooling agent which removes the heat released by the well area and thus allows a larger input of energy than in any other method known so far.

Title: Solvated mesophase pitches
Inventor: KALBACK WALTER M
IPC: C10C3/08
Filed: 1991-12-05
Granted: 2000-05-23
Abstract: This invention relates to low melting solvated mesophase pitches which are suitable for spinning into carbon fibers. The solvated mesophase pitches have a lower melting point than conventional mesophase pitch but remain substantially anisotropic. The solvated mesophase can be produced as an intermediate during solvent fractionation or supercritical solvent fractionation of mesogen-containing isotropic pitches. The process is enhanced through the ability to recover pseudomesogens with an increased average molecular weight which, in combination with the solvent content, provides a fusible mesophase capable of being spun directly into infusible oriented anisotropic carbon fibers.
