Abstract: A closure for a liquid container includes a base portion and a top portion. The base portion includes a top deck and an outer skirt extending from an outer end of the top deck in a lower direction away from the top deck. The outer skirt comprises a fastening means to interconnect the closure to the container neck. The top deck further has a spout extending in an upper direction away from the top deck. The top portion includes an annular base interconnectable to the base portion and a cover having an outer wall. At least one tamper element extends from the annular base in the upper direction above the annular base along the outer wall but spaced a distance apart from said outer wall. The tamper element is also initially interconnected to the outer wall by a predetermined breaking linkage.

Abstract: A closure comprising a base body with a circumferential recess foreseen to receive a tamper band connected to a top cover. The circumferential recess comprises at least one circumferential protrusion extending in a radial direction into the recess which comprises at least one pillar extending in the radial direction into the recess, tamper band comprises at least one circumferential undercut foreseen to interact in a mounted position with the circumferential protrusion of the circumferential recess. The tamper band comprises at least one notch foreseen to receive at least one pillar arranged in the circumferential recess.

Abstract: A closure for a liquid container includes a base portion with a top deck and a spout extending in an upper direction (z) away from the top deck and an outer skirt extending from an outer end of the top deck in a lower direction away from the top deck. A circumferential recess encircles the spout and includes a radially outer first side surface and a radially inner second side surface and first locking means. A top portion includes an annular base and a cover with an outer wall interconnected to the annular base by a hinge. The annular base includes a radially outer first side surface and radially inner second side surface and second locking means. Assembled, the annular base of the top portion is arranged in the circumferential recess of the base portion and the first and the second locking means interact locking the cover with respect to the base portion.

Abstract: A phased microphone array capable of being placed in the free stream flow of a wind tunnel test section. The array consists of a plane of microphones on arms radiating out from a central hub. Microphones are placed along the length of the arms. The array is to be fastened to an articulated mount which allows it to be repositioned and be placed in a number of viewing positions. The ideal arms are symmetric airfoils that rotate about the longitudinal axis of the arm so that in free flow the airfoils point into the oncoming flow. Microphones placed at the leading edge will be located at stagnation points decreasing wind turbulence and boundary layer effects.

Abstract: Functional beamforming is a vast improvement over classical beamforming methods. Let v be a power greater than unity. The v-th root of the array cross spectral matrix is computed and used in classical beamforming. The v-th power of the resulting beamform map is then computed. This procedure significantly reduced sidelobes, increasing the dynamic range of the results. Assuming the standard model of an incoherent source distribution, it is shown that the computed map values are greater than or equal to the underlying source strengths. Increasing v decreases the map values, steadily reducing sidelobes and peak widths. Quantitative component spectra can be computed by integrating the maps over regions of interest without the errors caused by sidelobes when integrating classical maps. Deconvolution processing is unnecessary. The time and other computer resources required for the computation are virtually identical to classical beamforming.

Abstract: A phased microphone imaging array and repeatable sound source are used in concert to determine absorption and reflection coefficients of materials and spaces across a continuous frequency domain. Coefficients can be determined at normal and oblique incidences to the surface using beamforming software. The invention can be used in-situ without needing to alter the environment in which it is testing. Accurate results can be obtained at any distance from the array and sound source to the testing surface with relatively little material.

Abstract: Apparatuses and methods for selecting one or more seeds from a group of seeds based on a predetermined characteristic of the selected seeds are provided. In various embodiments, the seeds are selected from multiple containers of seeds and re-configured into a single container for later use. The apparatus includes an array of seed selectors that expel the selected seeds from the corresponding compartments through contact with the compartments. A transfer member then directs each expelled seed to a cavity of a collection tray or into an envelope or other receptacle. A controller may run operation of the apparatus and associate the selected seeds with the cavities and/or receptacle into which they are deposited. In this way, numerous seeds may be automatically selected substantially simultaneously or in rapid succession and re-configured in a short period of time and with limited user intervention.

Abstract: A novel method and apparatus for cathodic protection of reinforced concrete structures includes an anode structure having an electrically conducting tape that is prevented from directly contacting the surface of the concrete structure. An electrically conducting coating is applied over the tape and in contact with the concrete surface to form an anode electrically connected to the tape and the concrete surface. The tape may conveniently employ a commercially available graphite tape with an adhered, electrically insulating backing. A preferred electrical connection to the tape includes a bus bar that compresses the tape by means of a screw engaging a masonry anchor mounted in the concrete structure. Preferably, the bus bar screw also mounts an electrically insulating junction box to the concrete surface to enclose the anode connection. The junction box may also cover an opening in the concrete surface through which the cathode connection to a reinforcing member is made.
