Abstract: Electrical heating systems for mineral wells, particularly oil wells, in which the reservoir or "pay zone" is heat stimulated or some well components (e.g., the tubing) are heated, or both, by electrical power supplied to a multi-perforate electrode have the operating efficiency enhanced by effectively terminating the heating electrode, at both its top and bottom, at a distance inwardly of the pay zone equal to at least three times the diameter of the well casing. In some systems the electrical power connection to the main heating electrode is made through a section of the production tubing of the well, with an electrical contactor interconnecting the tubing and the electrode in the level of the pay zone; these systems also provide electrical isolation, within critical height limits, for the production tubing and the pump rod. Delivery of electrical power downhole of the well may be accomplished through an electrical cable, which may or may not be appropriately armored. Specific electrode constructions combine conductive and insulating materials to counteract galvanic corrosion while maintaining mechanical strength.

Abstract: A quadrature demodulator for deriving an in-phase (I) and quadrature (Q) component from an input RF signal comprises means (24,25) for down-converting the RF signal to an IF signal. The IF signal is sampled (27) and digitised by an ADC (28). A complex digital filter (29) is used as a phase splitter designed to pass the positive IF frequency +f₀ but block the negative IF frequency -f₀. The resultant complex signal is in IQ form. By using four times oversampling at the ADC (28) the digital filter (29) can be split cleanly into two smaller filter sections (30, 31). By using feedforward filters for both these filter sections (30 and 31) a high degree of phase linearity can be achieved with minimal distortion.

Abstract: Described is a digital-to-analog converter (46) for use in a timing control loop. The converter includes a plurality of cells (B1....BN), each activated in response to a timing loop control signal. The converter also includes a resistive current mirror, with a first resistance R1, providing a reference current which is mirrored in each cell by a current source FET. Each cell is constructed to switch the current from its current source FET through an output FET when a respective control bit provided to the cell is positive. Otherwise, the current is diverted through a sink FET. All of the cell output FETs are tied to a single resistance R2 which collects the currents of the active cells and provides the AC output of the converter. The converter's output is related only to the ratio R2/R1, thereby decoupling process, temperature, and voltage effects from the output of the converter.

Abstract: An audiovisual system (103) on an automobile includes a number of components or audiovisual devices having respective controllers that are connected to a communication bus (14), making up a bus-type communication network. The controller of one of the components serves as a master unit (200) and the controllers of the other components as slave units (200⁻₁ -200 -n ) for data communication. The master and slave units are allotted respective inherent physical addresses, and their functions, such as a tape deck, a tuner, etc., are allotted respective logical addresses independent of the physical addresses. For data communication between the master unit and one of the slave units or between one of the slave units and another slave unit through the bus, address data used to address the units contain physical and logical addresses. Since the physical and logical addresses are independent of each other, data communication can be effected with a high degree of freedom by using the physical and logical addresses in desired combinations.

Abstract: A CDMA system is disclosed which reduces the effects of multiple access interference, thus increasing channel capacity and achieving greater efficiency in the use of a given frequency bandwidth. The signal is received (701) and the codes for the various channels are applied in the usual way to detect the signals in each channel (702-703). The detected signals are then divided (711) into those with a high confidence level ( g     l   - g     m   ) and those with a low confidence level ( u     l   - u     k   ). The high-confidence signals are then recoded (721-722) and subtracted (727) from the received signal. The codes corresponding to the channels whose detected signals had a low confidence level are then applied (731-733) to the resulting signal to derive improved detected signals for those channels.

Abstract: Target area on a specimen surface is located in an electron microanalyzer system that includes an electron energy analyzer and an analyzer detector. An electron gun impinges a rastering beam of incident electrons across the surface, and a secondary electron detector provides corresponding signals for producing a scanning electron microscope image of the surface. Backscattered electrons effected from the incident electrons are passed through the analyzer for producing a further image that is superimposed on the SEM image to locate the target area to be subject to a separate microanalysis. Particularly for an electrically insulating specimen surface, the images are produced in a single frame of rastering, and surface area and beam current are sufficient to produce the images without substantial charge buildup.

Abstract: To combat oil spillages and for rapid uptake of the escaped oil or oleaginous substances, there serves a process in which high-temperature-blown glass wool is hydrophobised and simultaneously bound using silicone and a starch serving as binder. The glass wool treated in accordance with this is then combined to form a cuttable, mat-shaped framework and is expediently dried at 150 DEG C. The then cohering three-dimensional framework mats are applied to the contaminated water sites and are left there for complete absorption, and are then together with the absorbed oil, subjected to intermediate storage and then mechanically or thermally disposed of or reprocessed. A corresponding adsorber is composed of this fine-fibre glass wool which is prepared and configured by coating with silicone and starch in such a way that adsorption of the oil away from the water surface or the ground surface is then possible. <IMAGE>

Abstract: The purpose of this invention is to provide secondary resistance low temperature compensation in vector speed control at values that are close to the actual secondary time constant even at startup of the motor when the secondary time constant calculation operation is not carried out. 
     The invention consists of vector speed control devices 1 to 5 of the induction motor IM, with secondary resistance low temperature compensation of the electric motor being carried out by installing a secondary time constant operator (6) which detects the secondary time constant of the electric motor; a comparator/register (7) which holds and outputs low temperature data τ 2L  by comparing and holding the lower temperature one of register data and the output τ₂ of the aforementioned operator (6); and a damping unit (8) which, during operation, carries out replacement of sequential data with the output τ₂ of the operator (6), and, during shutdown, outputs values τ₂* to a slip angular frequency operator (5) of the vector control circuit, which values slowly change from the value τ₂ at the stop of operation to the value τ 2L . In another embodiment the value τ₂* can switch from the τ₂ value at the stop of operation to the value τ 2L  a predetermined time after the stop. 
     The value τ 2L  may instead be determined as the first calculated τ₂ value on initial operation after a stop for a predetermined time.
