Title: Continuous flow downhole gas separator for progressing cavity pumps
Inventor: OBREJANU MARCEL
IPC: F04C13/00
Filed: 1997-07-16
Abstract: The efficiency of progressing cavity pumps is drastically reduced if the liquid being pumped contains large volumes of gas.  To alleviate this problem a gas separator is provided which can be attached to the suction of a downhole pump to remove gas from the liquid being pumped prior to the liquid entering the pump inlet.  The separator comprises an elongate housing having an annular chamber with guides which direct the liquid gas mixture to flow in an annular path from the inlet to the outlet end.  During this flow centrifugal forces act to displace the gas content to the central region from which it is removed via a separate central gas outlet so that liquid delivered to the pump inlet is greatly reduced in its gas content.

Abstract: L'invention concerne un passe-câble à sécurité HF pour des câbles blindés, pourvu d'un dispositif d'étanchéité et comprenant une tubulure filetée (7) à insérer dans un alésage et un écrou de serrage (10) à monter sur la tubulure filetée, ainsi qu'un disque de butée annulaire (8) pressé contre un épaulement annulaire situé sur la tubulure filetée (7), par un joint d'écrasement (9) à comprimer par l'écrou de serrage (10). Selon l'invention, ce passe-câble est pourvu d'une douille isolante (4) dont l'extrémité intérieure avant comporte au moins une partie (6) faisant saillie dans le sens radial. En outre, il est prévu une douille de pression (5) glisser par le côté extérieur du blindage (3) sur la douille isolante (4). Afin de pouvoir obtenir une certaine marge de déplacement du câble dans le sens axial, le câble prémonté avec la douille isolante (4) et la douille de pression (5) serrée est déplaçable dans le sens axial par rapport à la tubulure filetée (7) dans la mesure où un épaulement annulaire comporte une cavité axiale (12) traversante à l'intérieur de la tubulaire filetée (7). Comparativement aux passe-câbles à vis connus conformes aux normes relatives à la compatibilité électromagnétique, ce passe-câble présente l'avantage d'éviter que la tresse de blindage du câble ne "s'effiloche" pendant la manipulation dudit câble, ce dernier ne pouvant être entraîné en torsion lors du serrage car la douille isolante (4) se bloque à l'intérieur de la tubulure filetée (1). La durée du montage des câbles s'en trouve considérablement réduite.

Title: Method and instrument for measuring receiving sir and transmission power controller
Inventor: ADACHI FUMIYUKI
IPC: H04B7/005
Filed: 1997-04-14
Abstract: An SIR measuring apparatus with a simple configuration capable of improving the accuracy of received SIR measurement in CDMA mobile radio equipment using pilot symbols. A received signal (20) is input to a synchronization detector (21) that regenerates the clock timing of symbols and frame timing equivalent to the repetition period of the pilot signal. An interpolating coherent detector (22) produces information symbols (23) obtained from the received signal (20) through absolute phase coherent detection. A decision signal power calculator (24) obtains desired wave power values. A quasi-interference power calculator (25) obtains differences between the power values of the information symbols and a fading envelope, and adopts the differences as the quasi-interference power. Integrators (26 and 27) integrate received desired wave power and quasi-interference wave power. An SIR measuring portion (28) divides an averaged received desired wave power integral by an averaged quasi-interference power integral to obtain the received SIR (29).

Filed: 1997-12-12
Abstract: A CMOS implementation of a Vernier delay circuit uses the gate-source/drain capacitance of a number of transistors in parallel to vary delay. The capacitance has a first value when a digital signal provided to the gate of the transistor is in an "off" state and a second value when the transistor is in an "on" state. By designing the circuit with a number of transistors having different capacitances, a digitally switchable variable capacitance is produced. The variable capacitance is then included in a fine timing delay RC circuit to provide a vernier delay circuit.
