Patent DE-3683309-D1 (DE)
Inventor: DYHR EINAR

Granted: 1992-02-20
Abstract: A choke valve especially used for regulating the flow volume and with it the back pressure of liquids or gas while drilling through shallow gas bearing formations from an off-shore drilJing platform comprises a flexible cylindrical valve element (8) positioned in the flow passage of the valve housing (1), the valve being designed such that the valve element's (8) flow area can be reduced by a radial reduction of the valve element. The flow area of the valve element (8) is equal to or larger than the remaining flow area of the valve. The valve has devices (10) for constricting the end of the valve element (8) being nearest to the outlet opening (3) of the valve. The valve element (8) is long enough that it is possible to compensate for the wear, to which the end is exposed, by sliding the valve element against the constricting devices (10) or by moving the latter along the valve element as wear proceeds. Only the valve element (8) is exposed to wear and no other parts of the valve are positioned within the wearing zone. The valve element (8), in its withdrawn position, has its total diameter free allowing a full flow through the valve. Accordingly, the valve does not disturb the flow under normal conditions and is not exposed to any wear. At a gas kick the well can be controlled during a long period as it is possible to compensate the wear on the valve element during operation.

Abstract: A stream of dust-laden gas in a channel simultaneously engages the flat ends of a transverse row of spaced baffle elements each of semi-circular cross-section. These form a grid structure with a row of downstream intermediate hollow elements, each with symmetrically curved sides whose downstream ends are almost completely bridged by an arcuate stripper plate, leaving narrow gaps between ends of curved sides and stripper plate. Centrifugal action increases dust-content entering these gaps, e.g., with 3-6% of gas flow carrying up to 40% of dust charge. Straight plates parallel with general gas flow direction project downstream from the baffle element crests, between the intermediate elements, to improve gas flow.

Abstract: A rectifier circuit comprises two Zener diodes (3,4) having substantially the same characteristic Zener voltage which are connected to receive a sinusoidal input signal via a low impedance buffer (8). A half-wave rectified signal appearing on line (17) has a DC bias equal to the Zener voltage which is removed by the operational amplifier (15). A low pass filter (20) provides a smoothed DC voltage output on line (21). The circuit may be used as an AC to DC converter or for the detection of signals ranging from several volts down to a few millivolts. Its linear response over a wide dynamic range and at small signal levels is an advantage over conventional silicon diode rectifier circuits which suffer distortion at low signal levels.
