Patent number: 10751907Abstract: A wood treatment apparatus for long-term treatment of wood has a cylindrical hollow body and a sleeve. The cylindrical hollow body has an inner end, during use located within the wood, an outer end, directed away from the inner end, an exit opening and an accommodating space accommodating a carrier material containing active wood-treatment substance. The sleeve is arranged around the cylindrical hollow body and, when the apparatus is not in use, closes the exit opening and, when the apparatus is used, frees the exit opening and brings the accommodating space into contact with the wood. The method provides driving the apparatus into the wood to position the exit opening near a site to be treated and displacing the sleeve to bring the accommodating space into contact with the wood, wherein the apparatus remains in the wood to allow the wood-treatment substance to be released pressureless into the wood.Type: GrantFiled: August 2, 2017Date of Patent: August 25, 2020Assignee: IML Instrumenta Mechanik Labor GmbHInventors: Erich Hunger, Sebastian Hunger, Fabian Hunger

Patent number: 6589545Abstract: The present invention relates to a method of controlling insect infestation whereby an insecticidal coating having an extended residual period of a few months to a year is applied to a surface. A removable cover may be positioned near the surface to create a substantially darkened region to exploit some insects' natural tendencies to hide in dark places during daylight hours. Alternatively, the insecticide may be applied prior to the hatching of the insect eggs to control the population upon hatching. The method is especially effective for controlling the presence of gypsy moth caterpillars on trees. The present method may be accomplished by covering a portion of a tree trunk with an insecticidal coating containing an active ingredient such as chlorpyrifos, pyrethroid, permethrin, or tralomethrin and covering the coated area with burlap. In addition, the method of the present invention can be used to control the presence of insects on the sides of houses or other structures.Type: GrantFiled: October 13, 2000Date of Patent: July 8, 2003Inventor: Bruce R.

Patent number: 6585991Abstract: Termite foods mixed together in a matrix suitable to be used as baits and attractants for termites are provided. This termite matrix is preferred by termites over naturally-occurring foods such as deadwood, trees and wood used in human constructions, and other known termite matrices. It comprises cellulose, water and termite-preferred nutrients. Methods of monitoring the presence of termites using such matrices, and methods of controlling termites using such matrices to deliver termite toxins are also provided.Type: GrantFiled: July 26, 2000Date of Patent: July 1, 2003Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Guadalupe M. Rojas, Juan A. Morales-Ramos, Edgar G. King, Jr.

Patent number: 6436384Abstract: An animal bedding composition and method of manufacture includes cut or shredded pieces of multiple panel corrugated cardboard kraft paper structures having an internal corrugated panel sandwiched between outer panels, and an adsorptive deodorizing ion exchange agent such as a zeolite dispersed throughout the cardboard pieces and carried on outer and inner surfaces of the pieces of cardboard and on outer and inner surfaces of the corrugations to provide a comfortable, hygienic and deodorized floor covering for animal stalls. An automated method of manufacturing the animal bedding composition is also described. The ion exchange agent attaches to surfaces of the corrugated cardboard which serves as a carrier to sanitize and deodorize a stall. The open structure of the cut corrugations provides mechanical load absorption, and a wicking action to aerate moisture from a stall.Type: GrantFiled: March 6, 1998Date of Patent: August 20, 2002Inventor: Carl V. Santoiemmo

Publication number: 20020098110Abstract: An exterior panel containing algaecidal properties is provided for inhibiting the growth of algae on roofing materials and exterior siding. Algaecide is applied to the exterior panel on the unexposed surface, i.e., the side of the panel, when installed, is not directly in contact with the effects of weather. Moisture such as rain, dew, melting frost or snow, contacts the exposed surface of the panel and water is transported to the bottom portion of the unexposed surface of the panel via capillary attraction. Water extracts the algaecide and distributes it to the exposed surfaces of the panels and all of the other descending panels.Type: ApplicationFiled: November 30, 2000Publication date: July 25, 2002Inventors: William David Graham, Daniel Nelson Leavell, David George Miller, Margaret Mary Woodside, Carla Ann Miller, David Paul Aschenbeck, James Spray Belt
