A device for filtering air for a user comprising a frame formed in a generally oval-shaped band, the band encircling the user's head, with an upper portion above the user's head and a lower portion proximate to and spaced apart from the user's chin, an intake aperture formed in the frame, and an intake air filter covering the intake aperture. The device includes an air mover chamber attached with an air-tight seal to an inside surface of the frame and communicating on one end with the intake air filter and communicating on another end with a filtered air supply inlet inside the device and an air mover disposed within the air mover chamber and configured to draw air through the intake air filter and push air out the filtered air supply inlet. The device also includes an exhaust aperture formed in the frame and an exhaust air filter covering the exhaust aperture. The device further includes a transparent face shield attached with an air-tight seal to a front surface of the frame, the shield providing a space for air between an inside surface of the face shield and the user's face, and a fabric component comprising a first portion that is air permeable configured to cover the frame and filters and a second portion that is air impermeable extending from a back surface of the frame to cover a remaining portion of the user's head and encircle the user's neck.

A winch is disclosed having a drive cylinder, configured to be rotated by an applied force about its longitudinal axis and having at least three drive grooves. The winch also includes an idler with a longitudinal axis spaced apart from the longitudinal axis of the drive cylinder. A line is fed onto the winch by passing it over a first of the at least three drive grooves then around the idler and then around a second of the at least three drive grooves. The line is attached to one of a fixed object or the object to be moved. The winch is attached to the other of the fixed object or the object to be moved. As the applied force is applied to the drive cylinder, the line is gripped by the at least three drive grooves and a length of the line between the fixed object and the object to be moved is shortened, whereby the object is moved.

A slider has a drum with alternating alpha and beta grooves, first stacked pulleys, and second stacked pulleys. First and second end pulleys are at opposite ends of the slider. A line wraps as a loop from the last beta groove, around the first end pulley, to the last alpha groove, back and forth around the first stacked pulleys, off the first alpha groove, around the second end pulley, to the first beta groove, back and forth around the second stacked pulleys, and back to the last beta groove. When the drum or the end pulleys are driven, the difference in circumferences of the grooves causes the slider to move toward one of the first or second end pulleys.

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.

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.
