  • Polymer-based construction materials
    Patent number: 11987683
    Abstract: Aspects described herein are directed to compositions, systems, and methods of manufacturing a polymer-based construction material comprising polymeric resin and filler such as calcium carbonate (CaCO3). A surface of the polymer-based construction material may be treated such that the surface energy is increased from the material's inherent value to a predetermined value of at least 40 dynes/cm2. Further, the surface energy of the treated surface may persist within 20% of the predetermined value for at least three days.

  • Trap
    Patent number: 6832447
    Abstract: The trap (42, 82) is based around a spring mechanism (24, 60) comprising a substantially rectangular sheet of spring material folded to be substantially C-shaped in cross-section. In one embodiment (FIG. 6), portions (64, 65) of the spring mechanism (60) are adapted to be killing surfaces. In another embodiment (FIG. 2), the spring mechanism (24) is provided with arms (28, 29) that support jaws (36, 37). A setting mechanism (53/54, 77) holds the spring mechanism (24, 60) in an armed position and the trap (42, 82) is triggered when a trigger mechanism (49, 75) is moved by an animal which in turn disengages the setting mechanism (53/54, 77) and allows the killing surfaces (portions 64, 65) or jaws (36, 37) to come together on the animal therebetween.
