  • Patent number: 5749195
    Abstract: A malleable sealing membrane is used to seal openings, regions or other apertures in a house or similar structures to prevent the entry of pests or other unwanted elements. The sealing membrane includes a mesh substrate having a sealing compound coated on one or more sides and embedded within interstices of the mesh substrate. One or more release backings cover the sealing compound to protect the sealing compound prior to the application of the sealing membrane. The sealing membrane is prefabricated for later use in sealing applications. In use, the sealing compound on one side of the mesh substrate is exposed, for example, by removing one of the release backings. The exposed sealing compound is applied against the structure along the opening, region or aperture. The second release backing can then be removed.

  • Patent number: 5503333
    Abstract: An extension tube system for a dust particulate dispenser and a method of using the extension tube system are disclosed. The system includes a flexible duster extension tube having a central body portion with a first diameter, a first coupling end with a larger diameter, and a second dispensing end with a smaller diameter. Additionally, the second dispensing end includes a dust particulate collection region which serves to prevent dust particulates from spilling out of the duster extension tube when such action is not desired. The first coupling end is inserted over an outlet region of a dust particulate dispenser. Additional extension tubes can be connected to the second dispensing end of an extension tube to extend the reach to an area where dust particulates must be applied. A flexible duster extension tube cleaner having a cleaning element is used to clean remaining dust particulates from within the extension tubes.

A flexible duster extension tube cleaner having a cleaning element is used to clean remaining dust particulates from within the extension tubes. After the dust particulates are dispensed through the extension tube system, each extension tube is disconnected, and the tube cleaner is gripped at one end so that the cleaning element at the other end can be inserted into each flexible duster extension tube.
