  • Patent number: 8235689
    Abstract: A reciprocating piston liquid pump and piston driver mechanism includes a reciprocating piston liquid pump having a piston chamber and a piston reciprocating in the piston chamber from an unactuated position to an actuated position, with movement of the piston from the unactuated position to the actuated position causing the advancement of product. The piston driver mechanism includes a first driver member having an axis and a sloped circumferential surface extending along its axis, and a second driver member having an axis and a sloped circumferential surface extending along its axis. The first and second driver members are aligned along their axes and mate at an unactuated position along at least a portion of their sloped circumferential surfaces. Rotation of one of the driver members about its axis relative to the other of the driver members causes the second driver member to advance away from the first driver member toward an actuated position.

  • Patent number: 5565032
    Abstract: Apparatus for preserving porous structures, including masonry structures with embedded structural steel or reinforcing steel elements, applies a liquid preservative material to an exposed surface of the structure using the force of a compressed air blast at high velocity to meet, atomize, and inject the liquid preservative deeply into the porous structure. Separate manifolds each having multiple spaced nozzles are provided for the liquid preservative and for the air blasts, both manifolds being covered by a shroud. The manifolds and their nozzles are positioned and arranged so that, as the liquid is deposited on the surface of the structure, the high-velocity blast of air, arriving at the same area at the same time, atomizes, injects and forces the liquid into the interior of the structure, so as to coat the intersticies of the inner porous structure, including any reinforcing steel therein, the high-velocity air blast acting as a fluid hammer.

  • Patent number: 5114281
    Abstract: A machine for blowing loose thermal insulation into cavities in the walls, ceilings, and floors of buildings is contained within a smooth box-like housing that is easily moved about within a house on its own wheels and is easily transported to and from a job site. The housing encloses an equipment cavity and has a hopper located above the equipment cavity, but the hopper, into which the loose insulation is placed, is octagonal so that corner channels exist within the housing between the sides of the hopper and the corners of the housing. The equipment cavity at the bottom of the housing contains a motor which rotates an agitating wheel in the hopper, and that wheel has flexible tips that sweep the loose insulation over the floor of the hopper and into a feed hole in that floor. A grate extends through the hopper above the wheel to prevent access to the wheel in the bottom of the hopper.

  • Patent number: 4392611
    Abstract: An automatic control system for a vehicular liquid sprayer includes a control circuit for receiving a liquid pressure signal and a vehicle ground speed signal and operator accessible controls for delivering to the control circuit signals corresponding to a desired application rate, to the number of nozzles associated with the vehicular liquid sprayer and to the nozzle spacing. The operator may vary the input signal corresponding to desired application rate plus or minus a given percentage to compensate for tolerances in the liquid sprayer system. The control circuit calculates the liquid pressure necessary to achieve the desire application rate and the difference between this desire liquid pressure and the measured liquid pressure and produces control signals corresponding to this difference. A duty cycle control circuit converts these control signals to a cyclical control signal for driving a motor-driven flow control valve.

  • Patent number: 4296875
    Abstract: The foam dispensing apparatus is mountable on a self-propelled or manually propelled vehicle such as a planting, fertilizing and spraying machine or like surface working vehicles. A peristaltic or squeeze type pump has an inlet section for receiving air and a foam agent solution which are mixed and successively moved through the pump for discharge in a foam form from the pump outlet section. A discharge nozzle connected to the outlet section is arranged to apply the foam material on the ground surface at a position adjacent to one side of the vehicle. The pump is driven at a rate in response to the ground speed of the vehicle over the ground surface and the air and foam agent solution mixture may be proportionally varied to maintain visual observance of the foam on the ground surface for varying time periods.
