  • Patent number: 8540937
    Abstract: A system and/or method formulates a chemical solution using both volumetric and weight based measurements of components of the chemical solution. The components of the chemical solution include water and at least one other component, which may take any form, such as, without limitation, liquid, solid, powder or gaseous form. Formulation of the chemical solution is administered by combining water with the one or more other components at an output port, from which this combination is dispensed to a solution storage tank. In response to a user's request to formulate a specified amount of the chemical solution, the volume of water provided to the output port is monitored by a flow meter and the weight of the other component(s) provided to the output port is monitored by one or more load cells. Based on such monitoring, appropriate amounts of water and the other component(s) are combined together to formulate the specified amount of the chemical solution in the solution storage tank.

  • Patent number: 8383207
    Abstract: A tire dressing system includes an imaging device that captures an image of a vehicle tire or portion thereof and at least one application device that applies tire dressing to the tire based on the captured image. The system determines one or more tire parameters based on the captured image. The tire dressing system configures the at least one application device based on the tire parameter(s) such that the application device substantially restricts application of tire dressing to within the boundaries of the tire sidewalls. By determining the tire parameters, the tire dressing system may apply the tire dressing to the tire sidewalls while reducing or minimizing application of tire dressing to the body or rims of the vehicle.

  • Publication number: 20120087987
    Abstract: The present disclosure relates to the combined use of two pesticides. A first pesticide composition provides an initial contact kill, and may form a barrier when applied to greasy surfaces. A second pesticide composition provides residual pesticidal activity on the surface. Methods of making and using the pesticide compositions are also provided.

  • Patent number: 7753235
    Abstract: The invention generally relates to a foot activated dispenser and more particularly to a foot activated dispenser for dispensing a liquid product such as a skin care product (i.e. hand soap, hand sanitizer, surgical scrub, lotion, etc.). More specifically, the foot activated dispenser includes a bladder connected to tubing that is connected to a piston pump. The piston pump is located within a shroud that is removably attached to a wall bracket. The wall bracket includes a bottle retainer for holding a bottle having a pump.

  • Patent number: 7066356
    Abstract: The present invention is a foam soap dispenser (10) for push operation. The dispenser (10) houses a product bottle (18 and 18?), and the dispenser (10) includes lock-out members (12a and 12b) while the product bottle (18 and 18?) includes mating lock-out members (19a, 19b, and 19?) to ensure that the correct product is used with the dispenser (10). The dispenser (10) includes a push handle (13) that pivots on a pivot point (16) to dispense product when the push handle (13) is compressed. Pushing the push handle (13) moves the handle lever assembly (25 and 25?) components, which in turn activates a product outlet (23) to dispense the product. As the handle (13) is being compressed and released, a gap (22) is created and an anti-pinch member (14) helps prevent pinching of the hand.

  • Patent number: 6266143
    Abstract: A laser alignment target includes a disk shaped and transparent target body with an annular inclined mounting surface, a back plate having an annular inclined retaining surface, and a torroidal alignment member retained in a generally V-shaped groove formed by the mounting and retaining surfaces. The target body has an outer rim with an annular and transverse reference surface positionable against the end edge of a pipe section to axially align the target. With the target body positioned against the pipe section, the back plate is drawn axially toward the target body, compressing the alignment member between the mounting and retaining surfaces and an inside surface of the pipe section. The compression produces radial forces that tend to radially center and secure a target. The preferred alignment member is an elastically compressible gasket that provides a fluid tight seal. Alternative alignment members include a closely wound helical coil and an inflatable torroidal casing.
