  • Publication number: 20050132636
    Abstract: A flexible blanket is made of plural layers including a pair of mutually insulated electrically conductive layers. Electrically conductive stitchings extend between the electrically conductive layers, and a top abrasion resistant layer and are exposed on its exterior surface. A voltage potential is applied between the conductive layers so that the exposed stitches can provide an electric shock to an animal's foot when it is brought into contact with the exposed surface.

  • Publication number: 20050095154
    Abstract: A bezel and bezel assembly in which the bezel is a rigid block with a plurality of cavities. A depression in the block has ribs extending up therefrom to form an elevated contour. The depression includes at least one cavity therein for the application of air pressure into the depression and over the elevated contour. A gasket fits over the bezel so that positive pressure applied through the at least one cavity in the depression forces a gasket membrane to expand away from the pumping side and negative pressure applied through the at least one cavity in the depression pulls the gasket membrane against the elevated contour of the ribs. The bezel may include solvent bondable tubing connections for making pneumatic connections to the bezel.

  • Publication number: 20050095576
    Abstract: A system, device, and method for mixing a substance with a liquid pumps the liquid into a container of the substance to produce a solution. The container may be part of a container assembly including a port assembly for coupling with the container to produce an inlet and/or and outlet port for the container. The container assembly may be received within a receiving chamber for causing the coupling. The solution may be permitted to flow out of the outlet port when the solution rises within the container to a level of the outlet port so that the substance is partially diluted before flowing out of the outlet port.

  • Publication number: 20050094485
    Abstract: A system, device, and method for mixing liquids involves pumping a first liquid into a first pump chamber of a pumping apparatus through a channel of the pumping apparatus and pumping a second liquid from a second pump chamber of the pumping apparatus into either the channel or the first pump chamber, preferably while the first liquid is being pumped into the first pump chamber, so that the two liquids are mixed within the pumping apparatus. The second liquid is preferably pumped in a pulsatile mode in which small quantities of the second liquid are pumped at intervals. The quantity and/or the interval can be dynamically adjusted to result in a predetermined concentration of the two liquids. The contents of the first pump chamber are pumped to a receptacle.
