Abstract: Implementations for monitoring seismic data recorded in a marine survey of a subterranean formation for coverage gaps are described herein. Implementations include computing Fresnel sum operators for Fresnel zones of the subterranean formation based on a Kirchhoff migration impulse response at horizons of a representative plane layer model of a survey area of the subterranean formation. Implementations also include computing an acceptability map of the survey area based on the Fresnel sum operators. The acceptability map reveals coverage gaps in the survey area. Geoscientist may use the acceptability map to infill seismic data in areas of the survey area that correspond to the coverage gaps.

Abstract: A machine tool comprises a machine frame, a first spindle having a first workholder rotatable about a first axis, a second spindle having a second workholder rotatable about a second axis, a first tool carrier for machining one side of a workpiece in the first spindle, and a second tool carrier for machining a different side of a workpiece in the second spindle. The second spindle is arranged on a spindle carrier movable relative to the machine frame, using a carriage system, in parallel with and transversely to the first axis. The second workpiece spindle is pivotal on the spindle carrier, using a pivoting device, about a pivot axis that extends perpendicularly to a movement plane. The second tool carrier is positioned on a guide carriage movable relative to the machine frame in parallel with the pivot axis. A drag frame conveyor is provided to feed or transport workpieces.

Abstract: A respirator directional valve (10) includes a valve housing (12), a plurality of valve flaps (16-18), which can be moved by a gas stream or by a flowing medium and are arranged at the edge, and a number of support surfaces (20-22) as a valve seat. A number of support surfaces (20-22) corresponds to a number of valve flaps (16-18). Each valve flap (16-18) is adapted to a surface of a respective support surface (20-22). The support surfaces (20-22) are sloped in relation to a cross-sectional surface through the valve housing (12). The support surfaces (20-22) together form a tip pointing in the flow direction of the respirator directional valve (10).

Abstract: A mask adapter (10), for connecting two breathing tubes (210) of a closed-circuit respirator (300) to a breathing mask (400), includes a mask connection (20) for a fluid-communicating connection to a breathing area (410) of the breathing mask (400) and two tube connections (30, 40) with tube connection axes (32, 42) for a fluid-communicating connection to a breathing tube (210) each. The first tube connection (30) has an incoming air valve (34) and the second tube connection (40) has an outgoing air valve (44). The first tube connection axis (32) of the first tube connection (30) further forms an acute tube connection angle (?) with the second tube connection axis (42) of the second tube connection (40).

Abstract: A breathing bag (1) for a closed-circuit respirator (100) has a bag component (2), which encloses an inner volume (3). The bag component (2) can reversibly assume at least one unfolded state (4) and a folded-in state (5). The bag component (2) encloses a larger inner volume (3) in the unfolded state (4) than in the folded-in state (5). Moreover, a closed-circuit respirator (100) is provided, having at least one counter-lung, a filter device, an oxygen source as well as a housing. The counter-lung, the filter device and the oxygen source are arranged in the housing.

Abstract: A breathing bag (20) has a tray section (21) and a bag section (22). The tray section (21) and the bag section enclose an inner volume (24) of variable size, the bag section dipping at least partially into the tray section to reduce the size of the inner volume. A system (10) includes the breathing bag, for a closed-circuit respirator (100), with a dispensing valve unit (40) having a dispensing valve (41) providing a quantity of gas in a breathing circuit. An actuating unit (42) is functionally connected mechanically to the dispensing valve for actuating the dispensing valve. A lever component (50) is functionally connected mechanically to the actuating unit for activating the actuating unit. A closed-circuit respirator has the system including the breathing bag and the dispensing valve unit. A process is provided for mounting the system, including breathing bag and dispensing valve unit, in the closed-circuit respirator.
