  • Publication number: 20190168657
    Abstract: A truck bed cargo lift and loader is provided consisting of a pivotable and extendable platform or tray whose side supports are connected to linkage bars attached to carriers located in proximity to each base beam on the side of the lift and loader towards the open end of the truck bed, and which carriers travel along a worm gear jack screw with opposing threads installed in the cross member connecting the side base beams, such that when the jack screw rotates upon being driven by an electric motor or by a manually operated hand crank connected to a gearbox attached to the jack screw, the carriers travel towards and away from each other depending on the direction of rotation of the jack screw thereby raising and lowering the linkage bars with their platform or tray.

  • Publication number: 20190015693
    Abstract: A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a brake that is structured to apply a selectively variable resistance against rotation of the shaft relative to the structural frame. A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a gripping member mounted to the structural frame and structured to adhere to an external support surface. A method includes operating the FEPS device by rotating the shaft.

  • Publication number: 20180007877
    Abstract: The present invention is directed to an improved fishing rod guide. In one embodiment the improved fishing rod includes superhydrophobic metal guides. The superhydrophobic metal guides make it possible for fishing line, including, for example, fly fishing line and conventional fishing line, to move through the guides with less weight and drag due to water and ice accumulation, allowing for significantly greater distance and ease in casting. Additionally, the decrease in friction between the fishing line and line guides help extend the life of the fishing line.

  • Patent number: 9475635
    Abstract: An actuator with an anti-drool valve is provided for attaching to or mounting on an aerosol container. Aerosol actuators, and more recently trigger actuated aerosol actuators, may include a manifold which fits to or communicates with a valve on an aerosol container or can. Aerosol containers or cans typically contain a propellant such as a compressed gas or a volatile hydrocarbon. The contents of the container, along with the propellant, are held in the container by a container valve.

  • Patent number: 7775405
    Abstract: A sprayer includes a discharge valve assembly and includes an integrated poppet valve, spring and volume reducer. The spring includes more than omega-shaped form, each with relatively flat sides. The spring can have sides with portions sufficiently wide to substantially extend across the valve chamber to provide stability to the spring and prevent buckling. The flat sided omega-form construct is relatively easy to manufacture via molding and the ends of such construction provide suitable locations for integrated molding with the valve and the volume reducer.

  • Patent number: 7255294
    Abstract: A three part housing for a battery powered spray head includes a left half shell, a right half shell and a hinged top. The batteries are located in the upper portion of the housing below the hinged top (battery cover). The inner front of the top is provided with a downward depending latch member and a spring biased latch member is provided inside the housing. The spring biased latch member is actuated by inserting a pin (or stylus) through a hole in one of the half shells. This prevents accidental opening of the battery cover.

  • Patent number: 7175741
    Abstract: Hydrogen sulfide is removed or reduced in absorbent products by the use of a particulate material attached to pulp fiber by a retention aid. The particulate material can remove or reduce the hydrogen sulfide in the environment surrounding the fiber. Suitable materials are zinc oxide, calcium oxide, cupric oxide, magnesium oxide, manganese dioxide, manganese oxide and aluminum oxide. Zeolites are also suitable. The particulate material may be combined with a filler prior to attachment to the fiber.

  • Publication number: 20060153709
    Abstract: A three part housing for a battery powered spray head includes a left half shell, a right half shell and a hinged top. The batteries are located in the upper portion of the housing below the hinged top (battery cover). The upper edges of the half shells are provided with flanges which are received inside the cover when the cover is closed. The left and right half shells are also provided with a gutter-like structure adjacent to the battery cover which extend across the sides and down the back of the housing.

  • Publication number: 20060153707
    Abstract: A battery operated spray pump includes a piston pump having a double wave cam which is pushed by a pair of rotating cam pushers coupled to the electric motor via a gear transmission. The double wave cam has an unequal duty cycle, i.e. takes more time to expel fluid from the piston cylinder than it takes to fill the cylinder. The cam pushers rotate at a speed which, in conjunction with the duty cycle of the cam, produces a low pressure nearly constant stream.
