Publication number: 20250280816Abstract: An insect trap (1) may include a first housing (10); a reservoir (40) at least partially defined by the first housing (10); a protrusion disposed within the reservoir (40) and extending inward from an interior surface of the first housing (10), the protrusion (42) configured to pierce a package disposed within the reservoir (40); an actuator (44) connected to the protrusion (42) such that when the actuator (44) is moved, the protrusion (42) moves with the actuator (44) within the reservoir (40); a second housing (60) moveably engaging the first housing (10); a trap chamber (70) partially formed by the first and second housings (10, 60); an inlet (72) into the trap chamber (70); and wherein the second housing (60) is movable between a first position where the inlet (72) is open and a second position where the inlet (72) is closed. The trap (1) may include a package (152) enclosing an attractant composition.Type: ApplicationFiled: January 14, 2025Publication date: September 11, 2025Inventors: Paul M.

Patent number: 11553717Abstract: Disclosed is a composition of volatile and less-volatile pheromone components that can be used alone or in combination with other compounds to attract and/or arrest bed bugs of both sexes and all developmental stages. This blend can be used to bait traps that are effective in capturing bed bugs in infested premises or can be combined with a pesticide that is lethal to bed bugs.Type: GrantFiled: April 21, 2021Date of Patent: January 17, 2023Assignee: Simon Fraser UniversityInventors: Regine M. Gries, Robert A. Britton, Michael T. Holmes, Gerhard J. Gries

Patent number: 7067494Abstract: This invention provides analogs of eleutherobin and the eleuthesides modified at the C-11 position or comprising an epoxide functionality from C-11 to C-12. C-11 to C-12 is an ideal location for conjugating functional moieties to the eleutherobin pharmacophore without significant loss of antimitotic activity. Moieties that may be conjugated at C-11 include those intended to increase the solubility of the pharmacophore, to facilitate drug formulation, or to facilitate in vivo delivery or targeting.Type: GrantFiled: June 25, 2002Date of Patent: June 27, 2006Assignee: The University of British ColumbiaInventors: Raymond J. Andersen, Michel Roberge, Robert A. Britton, E. Dilip De Silva

Patent number: 6132954Abstract: The present invention provides for methods of screening for agents which delay the cell cycle and methods of delaying the cell cycle. Analogues of Era having arginine, histidine, or lysine at amino acid codon 17 are embodied by the present invention. Human and other homologs of bacterial Era amino acid and nucleic acid sequences are provided in the present invention. Vectors, host cells, protein preparations, cell cultures, and compositions comprising said analogue are also set forth in the present invention.Type: GrantFiled: August 20, 1997Date of Patent: October 17, 2000Assignees: Baylor College of Medicine, The United States of America as represented by the Department of Health and Human ServicesInventors: James R.

Patent number: 5220099Abstract: A process for purifying linear paraffins in which a hydrocarbon stream containing linear paraffins contaminated with aromatics, sulfur-, nitrogen-, and oxygen-containing compounds, and color bodies, but essentially free of olefins, is contacted with a zeolitic solid adsorbent such as a NaX zeolite or zeolite MgY. After adsorption the zeolitic solid adsorbent is desorbed with an alkyl-substituted aromatic desorbent such as toluene.Type: GrantFiled: August 31, 1988Date of Patent: June 15, 1993Assignee: Exxon Chemical Patents Inc.Inventors: James L. Schreiner, Robert A. Britton, Charles T. Dickson, Frederick A. Pehler, Jr.
