Abstract: The container includes a first chamber connected to the liquid source through an inlet port of a given cross-sectional area and a second chamber connected to a drain through an outlet port of at least equal size. The chambers are separated by a partition having a slot which has an elongated portion extending from the container floor in a direction generally parallel to the container side walls. The area of the elongated slot portion is approximately equal to the area of the inlet port. Liquid level or weight sensors generate signals representative of the quantity of the liquid level in the first chamber to a microprocessor to measure the flow rate. The signals are integrated over time to measure the total volume.

Abstract: A method is disclosed for processing of dual sensor OBC data that corrects for angular incidence angle, corrects for estimated reflectivity, and combines the corrected sensor traces using an optimal diversity scaling technique. In one embodiment, the disclosed method takes seismic traces from a geophone and a hydrophone, corrects the geophone trace for the incidence angle, determines diversity filters for optimally combining the geophone and hydrophone traces, applies the diversity filters, estimates a reflectivity coefficient for the ocean bottom (potentially for different angles of reflection), scales the geophone data according to the reflectivity, and re-applies the diversity filters to obtain a combined trace. The combined trace is expected to have various artifacts eliminated, including ghosting and reverberation, and is expected to have an optimally determined signal-to-noise ratio.

Abstract: There is disclosed an accelerometer comprising a substrate, a proof mass mounted to the substrate for movement in a first direction perpendicular to the plane of the substrate, the proof mass carrying a first sensing electrode, a second sensing electrode mounted relative to the substrate, wherein the first and second sensing electrodes comprise surfaces extending at an angle relative to the substrate and defining between them a sensing gap the width of which varies with movement of the proof mass in the first direction.

Abstract: Device for connecting a first duct of a very small diameter, such as for instance a needle or a capillary column, to a second duct, wherein the device comprises a receiving part and a sealing element, wherein the receiving part is provided with a duct bore in which the first duct is slidably receivable, wherein the receiving part is also provided with a sealing-element bore which intersects the duct bore and in which the sealing element is slidably received, wherein the sealing element is provided with a recess, wherein the sealing element is adapted to assume a sealing position in which the duct bore is sealed, and is adapted to assume a connecting position in which the two duct bore parts on either side of the sealing-element bore are in fluid connection with each other via the recess, wherein the sealing element is biased in the sealing position by a spring under spring action.
