Abstract: A system and method for removal of uranium and other contaminants from aqueous solution, utilizing live algae, are described. The system includes a bioreactor, in which a reaction mixture of live algae, preferably photosynthetic algae, and contaminated solution are introduced; a means for introducing carbon dioxide gas in the reaction mixture; a means for exposing the reaction mixture to light; means for mixing and impelling the reaction mixture; and means for separating out algae from remediated solution.

Abstract: A particle refining apparatus to be integrated into a system including a containment device and an influent conduit. The influent conduit is configured to retain the particle refining apparatus and connected to the containment device. The particle refining apparatus including a shaft, a blade set attached near the end of the shaft and attachment couplings arranged within the influent conduit. A method for refining particles includes introducing particles into an influent conduit, chopping the particles to a desired size with an initial chopping apparatus, directing the chopped particles through the influent conduit, refining the particles to a desired size with a refining apparatus, and moving the particles continuously from the influent conduit through the refining apparatus and into a containment device.

Abstract: An adjustable filter, particularly for use as an antialiasing filter in digital telecommunications networks, includes adjustable capacitors which determine frequency response for the purpose of accurate alignment with a particular cut-off frequency. The active filter includes, in line with the invention, a control device with a measuring device for ascertaining the actual cut-off frequency of the filter. On the basis of the ascertained actual cut-off frequency of the filter and the information about the nominal cut-off frequency which is to be set, an adjustment parameter for the adjustable capacitor is selected from a memory arrangement. This adjustment parameter is used to adjust the adjustable capacitor such that the desired nominal cut-off frequency is obtained and, at the same time, the alignment is performed to achieve the nominal cut-off frequency with sufficient accuracy.

Abstract: A static air freshener has a frame formed of or with plastic beads impregnated with a scent or aroma. The rate of release of the scent is controlled by the area of the frame to define the useful life of the air freshener. An insert may be place in a void defined by the frame. The insert has a thematic image that may be correlated to a thematic image on the header card of a bag or sack sized to contain the air freshener for positioning at or on the point of sale device.

Abstract: A powder inhaler includes a container for storing powdered medicament. A metering member has a dosing recess and is moveable between a filling position in which the dosing recess is in alignment with an opening of the container, and an inhalation position in which it is in alignment with an inhalation channel. A mouthpiece is in communication with the inhalation channel for enabling inhalation of the dose of powdered medicament when in the inhalation position. A protective member provided between the metering member and the inhalation channel is moveable between a closed position in which the protective member covers the dosing recess, thereby preventing powdered medicament contained in the dosing recess from entering the inhalation channel, and an open position in which the protective member does not cover the dosing recess, thereby exposing the dosing recess to the inhalation channel for enabling inhalation of the dose of the powdered medicament.

Abstract: A method for estimating the frequency shift of a CPFSK signal includes scanning the CPFSK signal. Intermediate signal values are determined for the scanned CPFSK signal. An estimated value (?) is determined for the frequency shift of the CPFSK signal by assessing a predefined number of L0 consecutive intermediate signal values. An integer delay parameter D is specified. Intermediate signal values for intervals k·T+? are determined in each case from scanning values of the CPFSK signal obtained for intervals k·D·T+? and [k?1]·D·T+?, whereby T designates a scanning period of the scanned CPFSK signal, k is a scanning index and ? is a delay constant. The estimated value (?) for the frequency shift is determined from the intermediate signal values for intervals i·D·T+? with i=0 . . . L0?1. The integer delay parameter D is variable and is selected depending on the type of CPFSK modulation used for the CPFSK signal.

Abstract: A CDR circuit arrangement, for example for a transceiver module, features a data recovery unit (4) for the recovery of the data contained in a received signal (DATA) by scanning this received data signal, and a phase evaluation unit for the determination of a suitable phase position for the scanning carried out by the data recovery unit (4).

Abstract: The present invention provides a chewing gum composition containing an active ingredient. The preferred chewing gum composition comprises a plurality of granules comprising a mixture of a powdered chewing gum base and a selected amount of a powdered active ingredient, said powdered chewing gum base and powdered active ingredient being mixed together within said granules. Additives may be mixed in the granules or may coat the granules. The preferred form is a tablet containing a controlled dosage form of the active ingredient.

Abstract: The present apparatus is directed, in one embodiment, towards a liquid-absorbing component for attachment to eyeglasses, that impedes the flow of perspiration and other materials into the wearer's eyes. In another embodiment, the apparatus includes a liquid-absorbing component that is attachable to eyeglass arms and may be used independently of eyeglasses.
