Abstract: A filter assembly includes a filter housing, a filter housing lid, a filter cartridge, an endplate, and a seal member. The filter housing defines a first cavity and comprises a return passage in fluid communication with the first cavity. The filter housing lid is selectively coupled to the filter housing and defines a second cavity coextensive with the first cavity. The filter cartridge is positioned within the first cavity. The endplate is coupled to a first end of the filter cartridge. The endplate is configured to interface with the filter housing. The seal member is coupled to the endplate and is configured to be received in the return passage. The endplate is configured to partially separate the filter housing from the filter cartridge.

Abstract: The present invention is directed to peptidomimetics having antibacterial activity, especially against Gram-negative bacteria. The peptidomimetics of the invention are compounds of the general formula (I), P1-P2-P3-P4-P5-P6-P7-P8-P9-P10-P11-P12-P13-P14-P15-P16 (I) and pharmaceutically acceptable salts thereof, as described in the description and in the claims. The invention is also directed to therapeutic uses of the peptidomimetics for the treatment or prevention of bacterial infections and diseases related to bacterial infections and to non-therapeutic uses of the peptidomimetics for preserving or disinfecting foodstuffs, cosmetics, medicaments or other nutrient-containing materials. In addition, the present invention provides an efficient synthetic process by which these compounds can, if desired, be made in parallel library-format. Moreover, the peptidomimetics of the invention show improved antimicrobial activity, low or no hemolysis of red blood cells and reduced cytotoxicity.

Abstract: An exemplary optical apparatus includes a coherent source of light having a frequency controlled by command signals. One surface of a spiral phase plate resonator receives the light and the light exits from different regions of another surface dependent on the frequency of the light. A fixed reflector is mounted adjacent the another surface to reflect the exiting light at about a 90 degree angle relative to the path of the exiting light. A source of the command signals sends different values of the command signals to the coherent light source to produce corresponding frequencies of the light that determine a particular region from which the light exits the another surface and hence a location on the fixed reflector where the light will be reflected. By changing the frequency of the light, the light is output in a plane by the optical apparatus with no physically moving components.

Abstract: A tank wetting method for wetting the interior of a tank of a vehicle such that residue from transported substance does not dry on interior surfaces of the tank. The tank wetting method utilizes a tank wetting appartatus (10) including an atomizing device (38) having at least one nozzle (56) disposed within the tank of the vehicle, and a reservoir (12) mounted on the vehicle for holding a liquid such as water. A liquid supply system is provided for selectively supplying water to the atomizing device (38), and an air supply system is provided for selectively supplying air to the atomizing device (38), whereby the atomizing device (38) mixes the air from the air supply system and the liquid from the reservoir (12) and injects the resulting atomized liquid into the interior of the vehicle's tank. In accordance with the method of the present invention, the substance being transported is discharged from the tank (18) of the vehicle, and the tank (18) is sealed such that the tank is substantially airtight.
