  • Patent number: 11945642
    Abstract: Disclosed herein is a sprung dispensing tower that includes a vertical housing having an open top and an interior dimensioned to receive products in a vertical stacked relationship. The sprung dispensing tower includes a platform within the interior of the vertical housing, the platform having a horizontal component and platform sidewalls depending from the horizontal component in parallel with respective interior sidewalls of the vertical housing, the platform being vertically slideable within the interior of the vertical housing between an uppermost position and a lowermost position. The sprung dispensing tower includes a compressible spring associated with an underside of the platform and biasing the platform towards the uppermost position. The sprung dispensing tower includes a resiliently compressible slide guide affixed to at least a portion of the platform sidewalls and extending laterally towards the interior sidewalls of the vertical housing.

  • Patent number: 10058829
    Abstract: This invention is a low pressure, steady volume supply static mixer manifold for a high pressure pump. The design comprises an internal diffuser cylindrical tube inside an external rectangular tube in which static mixing occurs. Capped at one end, the internal diffuser pipe, with flow coming from the opposite side, allows for one flow direction diffused into the outer rectangular tube that then allows for constant bidirectional flow at a constant pressure throughout. The flow of slurry components between the cylindrical tube and the rectangular tube supports static mixing in part by creating alternating flow pressures between mixing ports (allowing flow of slurry components from the cylindrical tube) and the exit ports based on the different geometries of the cylindrical tube and rectangular tube. The combination of flow and pressure exiting the cylindrical tube through the mixing ports, at an angle to the bottom corners of the outer rectangular tube, creates a natural agitation of the slurry components.

  • Patent number: 9703091
    Abstract: A magnification viewer lens device is provided that is used to magnify objects when viewed through the device. The device comprises a magnification lens housing supporting a magnification lens, whereby the housing is supported along its perimeter by an arm assembly. The arm assembly comprises an elongated arm and a clamp, whereby the arm assembly is rotatable relative to the housing and to the clamp. The clamp forms a rounded clamping member that is suitable for securing the device to a golf cart steering wheel or alternate support. The arm and the housing remains static relative to the hinge joints of the arm using friction hinges, while the housing supports a Fresnel lens for magnifying objects when viewed therethrough. In one embodiment, the housing is substantially rectangular and the arm and clamp are designed to secure the housing over the scorecard area of a golf cart steering wheel.

  • Publication number: 20170113195
    Abstract: This invention is primarily designed as a low pressure, steady volume supply static mixer manifold for a high pressure pump. A manifold fluid supply is achieved through the use of a centrifugal pump. The design comprises an internal diffuser cylindrical tube inside an external rectangular tube in which static mixing occurs. Capped at one end, the internal diffuser pipe, with flow coming from the opposite side, allows for one flow direction diffused into the outer rectangular tube that then allows for constant bidirectional flow at a constant pressure throughout. while adequately mixing all parts of the fluid makeup. The flow of slurry components between the cylindrical tube and the rectangular tube supports static mixing in part by creating alternating flow pressures between mixing ports (allowing flow of slurry components from the cylindrical tube) and the exit ports based on the different geometries of the cylindrical tube and rectangular tube.

  • Publication number: 20150002948
    Abstract: A magnification lens holder is provided for use with a golf cart steering column or for general use while shopping in a grocery store. The preferred embodiment comprises a magnifying viewer lens disposed within a housing that allows the lens to be removed and interchanged. A support assembly is provided having one or more ball joints and a clamp assembly for securing the same to the steering column of a golf cart. The viewer lens is positionable over or through the steering wheel of the cart to magnify a score card, whereby the viewer lens rotates with the steering column while driving. An alternate configuration is contemplated for supporting the viewer lens from a shopping cart or basket, providing the user with a magnifying lens while shopping and inspecting grocery items. The viewer lens housing is removable from the support assembly in both embodiments.
