  • Patent number: 7377072
    Abstract: Bait stations are provided which present the ability to monitor bait and expand capacity of bait without materially adversely affecting feeding activity. In one form a slow acting toxicant-laced attractant is provided in the station. The station has an outer housing, an openable opaque lid, and a transparent window moveable relative to both the lid and housing. One can move the lid while leaving the window in place, or move both the lid and window. Removal of both permits attachment of a second such housing to the first, while the first remains in place. The lid and window can then be affixed to the second housing. These stations can be used to control termites and other crawling pests.

  • Patent number: 7093389
    Abstract: Traps are disclosed for controlling flying insects such as wasps. The traps are pre-packaged with attracting liquid prior to sale, and then sealed with a peel-off film in a manner that prevents leakage prior to use. When the trap is about to be used, the peel-off film is removed to expose both a trap entry and a pivotable stand. A rain/sun shield is then mounted on the stand, preferably with the upper portion of the stand projecting through the shield to form part of a hanger.

  • Publication number: 20060119699
    Abstract: An imaging apparatus for imaging on a recording medium is improved to permit the imaging power to be balanced between various groups of individual radiation sources with a low outlay and high accuracy. Two or more imaging heads that respectively include a multiplicity of individual radiation sources that can be electrically driven individually with light beams directed onto a radiation-sensitive layer of the recording medium. A drive moves the recording medium and the radiation sources relative to one another. A control device controls the power of the light beams of the radiation sources separately for each imaging head. A least one light guide is provided that guides a portion of the light beams emanating from the radiation sources to the receiver surface of a photoelectric sensor, which sensor is connected to the control device.

  • Publication number: 20050271778
    Abstract: The invention relates to a method for producing pharmaceuticals or parts thereof or food supplements or parts thereof, by coating substrates for pharmaceutical uses or for using as food supplements for humans or animals, with a film-forming coating agent mixed with at least one other substance suitable for the cited purposes. The film-forming coating agent and the other substance first constitute separate liquid, sprayable individual portions, and are sprayed by means of at least one spray device which are provided, individually or together, with at least two separate nozzles for liquids, and have overlapping spray jets—in such a way that the individual portions sprayed out of the separate nozzles mix during the spraying process and the mixture forms a continuous film coating on the substrate, forming the food supplement, the pharmaceutical or the part thereof. The invention is characterized in that the coating agent and the other substance are in a concentration gradient from the inside to the outside.

  • Patent number: 6951172
    Abstract: A printing unit configuration includes an accessory and a connection mechanism moveably fastening the accessory thereto, throwing the accessory thereon into a working position, and removing it therefrom into maintenance positions. A linear guide can be connected to the accessory and disposed perpendicular to a pivot axis, with the mechanism pivoting the accessory away from the unit about the axis and displacing it along the guide. The mechanism can have two pivot axes disposed parallel to the unit rotation axis and can pivot the accessory away from the unit first about the first axis then about the second. The mechanism can pivot the accessory about an axis perpendicular to the unit rotation axis and/or about a single pivot axis disposed below the accessory. The mechanism can connect the accessory to the unit to project into a recess of a side wall of the printing machine at a side opposite an operator side in a maintenance position.
