Abstract: A device for simulating sound produced by certain equipment, for example a rotor-stator arrangement of a turbomachine, or for generation of opposing sound fields for active sound control, including active sound reduction and active sound amplification, comprises flow obstacles (2) provided in a flow duct (1) flown by a fluid at which vortices (5, 6) are shed at a certain frequency depending on the shape and size of the flow obstacles and the velocity of flow. The quantity and spatial arrangement of the flow obstacles is selected such that a periodically spatially and temporally changing pressure field for the excitation of a sound field (8) of a certain modal content is produced by the entirety of the vortices shed. This sound field reacts synchronizingly on the vortex shedding. The resonant circuit so formed, whose vortex shedding frequency is in the range of the resonant frequency of the sound field to be excited, is the sound source.

Abstract: A detector tube packaging is provided for packaging detector tubes with tips. The packaging includes a pushing insert for receiving a plurality of detector tubes located next to one another and a container for receiving the pushing insert via a first side of the container. A seal element may connect the pushing insert to the container. The seal may be broken to remove the insert and may be applied adjacent to or at a first side of the container. A detector tube opener is provided at another side of the container. The detector tube opener has openings corresponding to the number and the spacing of the detector tubes. The openings are located next to each other with each opening having an opening diameter substantially corresponding to a diameter of the tips of the detector tubes.

Abstract: A valve is provided for controlling a flow of a fluid between a first environment and a second environment. The valve includes a frame adapted to fit within a perimeter of an aperture in a divider separating the first environment from the second environment. The valve additionally includes a first gate movable within the frame to control a flow of the fluid through the aperture between the first environment and the second environment. The first gate includes a substantially aerodynamically clean surface substantially free from protrusions disrupting the flow of the fluid over the first gate surface. Additionally, the first gate includes a trailing edge having a baffle adapted to cover an aft edge of the frame when the first gate is positioned to have a small opening angle. The baffle includes a plurality of 3-D notches in a front side of the baffle.

Abstract: A valve for controlling a flow of a fluid between a first environment to a second environment. The valve includes a frame adapted to fit within a perimeter of an aperture in a divider separating the first environment from the second environment. The valve additionally includes a first gate movable within the frame to control a flow of the fluid through the aperture between the first environment and the second environment. The first gate has a substantially aerodynamically clean surface that is substantially free from protrusions that may disrupt the flow of the fluid over the first gate surface. The aerodynamically clean surface reduces coherent vortex shedding of the fluid as the fluid flows across the surface of the first gate. To further reduce vortex shedding, the first gate includes a rounded leading edge. Additionally, the first gate includes a trailing edge adapted to reduce edge tones.

Abstract: For use in a program of physical exercise, a hollow cylindrical tube made of rubber, which tube is calibrated along its outer surface with an 0 permanently imprinted at the midpoint between the ends of the tube and the numerals 1, 2, 3 and 4 imprinted along the outer surface of the tube at spaced intervals from the midpoint of the tube. The tube is approximately 75 inches in length and has an outer diameter of 7/8ths of an inch and an inner diameter of 3/4ths of an inch.
