    Abstract: There is described a shower system that includes a showerhead fixture and a base connected by conduits. The showerhead fixture includes an inlet for receiving pressurized water. A diverter is configured to divert at least a portion of the pressurized water to the base. The showerhead fixture also includes a second inlet fluidly connected to a recirculating showerhead portion with a plurality of showerhead jets for expelling mixed water received from the base. The base is configured to create a reservoir of water on a shower floor and includes a venturi pump capable of using pressurized water from the showerhead fixture to draw in water from the reservoir into the stream of pressurized water. The mixed water is sent from the base to the jets in the showerhead fixture to thereby increase the volume of water expelled from the showerhead.

    Abstract: A device for moving an object is disclosed. The device has a drive cylinder with drive grooves and a set of idler pulleys. The idler pulleys are on a shaft that is parallel to the drive cylinder. Each of the idler pulleys rotate at an angle around the drive shaft that aligns the grooves of the idler pulleys to neighboring drive grooves. This allows the line to pass onto the drive groove, around an idler pulley, and onto a next adjacent drive groove. The line therefore winds back and forth between the drive grooves, the idler pulleys, and back to the next drive groove. One end of the line is placed under tension and the other is attached to an object or to a fixed member. The drive cylinder is driven and the line is moved through the device, or the device is moved along the line, respectively.

    Abstract: A system for sanitizing water in a hot tub is described. The system includes a sanitizing chamber, separate from the hot tub, and sized to hold a small portion of the water from the hot tub. A first conduit for conveys water from the hot tub to the sanitizing chamber. A second conduit conveys water from the sanitizing chamber to the hot tub. A pump is provided that moves water from the hot tub, through the first conduit into the sanitizing chamber and from the sanitizing chamber, through the second conduit, back into the hot tub. A heater heats the water in the sanitizing chamber to a temperature and for a time sufficient to destroy or deactivate undesirable microorganisms.

    Abstract: A winch drum is disclosed. In a first aspect, a first set of teeth are positioned around an outer perimeter of a drum. The first set of teeth taper from a first crown to a first base. A second set of teeth are positioned around the outer perimeter of the drum. The second set of teeth taper from a second crown to a second base. The second set of teeth are offset from the first set of teeth such that a gap between the first bases and the second bases forms a sinusoidal channel for a line to follow the first set of teeth and the second set of teeth becomes a guide for the line so that the line can engage the sinusoidal channel. The line follows the sinusoidal channel and each change of direction along the sinusoidal path causes the line to engage by friction with the first bases and the second bases. In a second aspect, the drum includes a trough that follows a sinusoidal path and wherein the trough is narrower at its bottom than at its top.

    Abstract: A counterbalance system for an overhead door is disclosed. The system includes a torsion adjustment comprising a first portion and a second portion, the first and second portions being rotatable relative to one another in a first direction and not in a second direction opposite the first direction. The system also includes an anchor fixed to the first portion, a collar fixed to the second portion, the collar being selectively fixable to a shaft of the overhead door, and a spring coupled between the collar and the anchor. The spring supports at least a portion of the weight of the overhead door as the overhead door is raised and lowered. Rotating the first portion of the torsion calibration collar relative to the second portion of the torsion calibration collar increases torsion in the spring and therefore calibrates the spring to support a desired amount of the weight of the overhead door.

    Abstract: A device for covering the head of a user comprising a rigid component comprising a transparent face shield and an air port, a fabric component, wherein the rigid component and the fabric component combine to cover the head of the user and seal around the neck of the user, and an air mover mounted on the rigid component so as to cause air to move either into or out of the air port, a filter that filters air moving through the air port, wherein at least a portion of the fabric component allows air to either move into the device if the air mover moves air out of the air port or move out of the device if the air mover moves air into the air port, and wherein the at least a portion of the fabric allows air to move into or out of the device also filters the air moving into or out of the device.
