Title: Selective excitation of heating electrodes for oil wells
Inventor: BRIDGES JACK E
IPC: E21B47/12
Filed: 1996-04-25
Abstract: A control for an electrical heating system that enhances production from an oil well, particularly a horizontal oil well; the well includes an initial well bore extending downwardly from the surface of the earth through one or more overburden formations and into communication with a producing well bore that extends or deviates outwardly from the initial well bore into an oil producing formation.  The heating system includes an array of short, electrically conductive heating electrodes extending longitudinally through the producing well bore. The heating system further includes apparatus for electrically energizing electrodes that are close to each other with A.C. power; the A.C. power supplied to electrodes near each other has a phase displacement of at least 90°, usually 120° or 180°, between electrodes.  The control includes plural power switches, each connected to at least one heating electrode; each power switch is conductive only up to a predetermined limit (usually a temperature limit). In one embodiment, each power switch includes a sensor responsive to the operating condition of its heating electrode.  Another embodiment employs a telemeter circuit to actuate the power switches with sensors that are separate from the power switches.

Abstract: A car seat mat for use with a child's restraint seat over the  seat  of  an  automobile,  consisting  of  a  flexible waterproof sheet.  This sheet has a main, generally quadrangular section and a lip portion coextensive with the main section.  The sheet lip portion is sized for conforming to the seat portion of the child's restraint seat, and the sheet main portion is sized for overlapping the vertical car body panel straddling the front end of the car fixed seat and the car flooring.   A first, transverse, substantially rigid flange extends in between the sheet main portion and the sheet lip portion, and a second, substantially rigid flange extends at an end edge section of the mat opposite said first flange.  The first flange is sized for flat abutment against the front end portion of the child's restraint seat, and the second flange is adapted to form a water collecting pocket in spaced overlying fashion relative to the car flooring.   The sheet accordingly shields the car seat and straddling car body vertical panel from accidental sand and dirt spills generated by the bare feet, shoes or boots of an infant sitting in the child's restraint seat.

Title: Process and device for the electro-optical measurement of distance
Inventor: G CHTER BERNHARD
IPC: G01S17/10
Filed: 1995-09-21
Abstract: A process and device are proposed for the electro-optical measurement of distance based on the pulse delay method.      A number of individual light signal pulses are emitted at predetermined and differing intervals, so that after a number of measurement intervals which determine the measurement zone have elapsed, a pulse sequence is detected. Using mathematical estimation methods, the temporal position of the detected pulse sequence in relation to a reference pulse sequence can be determined and used to determine the delay tim~ By emitting individual pulses at long intervals and high peak power and subsequently combining them to form a pulse sequence, the accuracy of the distance measurement process is significantly improved.
