Abstract: A self-contained portable air distribution system for cooling an individual by the movement of intake and exhaust air flow streams over an individual. The system includes a portable rechargeable battery operated fan that produces both an inlet intake and outlet exhaust air flow streams that provides a cooling effect by evaporating body moisture as it passes over the body.

Abstract: A joint shaft, in particular a universal joint shaft, has first and second axial connection ends and a central part that connects the two connection ends to one another in a torsionally rigid and pivotable manner. At least one intermediate sleeve is provided between a first and a second shaft element with internal gearing having inner teeth, which are distributed over the circumference and extend in the direction of the longitudinal axis, and external gearing with outer teeth, which are distributed over the circumference and extend in the direction of the longitudinal axis. The sleeve is longitudinally displaceable relative to the first shaft element and to the second shaft element and is attached directly or indirectly in a torsionally rigid manner to the first shaft element by way of the intermediate sleeve external gearing and to the second shaft element by way of the intermediate sleeve internal gearing.

Abstract: A self-contained air distribution system for an individual which can distribute air over the chest, back, head, or skin of the individual, the system including a battery operated blower fan in communication with the plenum and manifold, the manifold having primary exhaust nozzles which may be attached to secondary distribution conduits extending over the chest, back, or head of the individual, thereby allowing air to selectively escape providing a cooling and evaporate effect.

Abstract: A self-contained helical air distribution system for the body of an individual which can distribute air over both the chest and back of the individual, the system including a battery operated blower fan in communication with the plenum and manifold, the manifold having a plurality of tubular distribution conduits, each conduit having a capped end, the conduits extending over the chest and back of the body, the conduits formed with a spiral helix cut allowing the tubular conduits to react to the motion of the human body, the spiral helix cuts reacting to such movement, thereby allowing air to selectively escape from the expansion of these cuts providing a cooling and evaporate effect. With slight adaptation the air distribution system can distribute heated air and also be used to control the ambient temperature about inanimate objects, such as computers, electronic instruments, windshields, and car seats.

Abstract: These and other objects of the present invention are achieved by a brush holder assembly for an electric motor or generator wherein the brush box or holder is arcuate and curved in relationship to a commutator and supports a brush means and a floating constant force spring which allows dynamic movement and control of the brush as it moves towards a commutator.

Abstract: An apparatus for elevating a fluid includes: a pumping member rotatable about a vertical axis, the pumping member having at least one ramped path, the ramped path having a lowermost portion insertable below the surface of a fluid to be elevated, and an uppermost portion that is more distant from the vertical axis than the lowermost portion thereof; a catch chamber surrounding a circular trajectory of the uppermost portion as it rotates about the vertical axis and positioned to receive fluid expelled from the uppermost portion; and a motor coupled to the pumping member for imparting rotational motion to the pumping member about the vertical axis, the motor having sufficient power to generate a centrifugal force that will drive the fluid from the lowermost portion of the ramped path to the uppermost portion and into the catch chamber.

Abstract: A multi-piece safety wheel includes a plurality of circumferentially spaced, interlocking bosses and tabs on the inner rim portion and outer rim portion. In the event of improper disassembly of the wheel with an inflated tire mounted thereon, any failure of the wheel assembly fasteners will result in the outer rim portion separating from the inner rim portion a sufficient distance to vent air pressure from within the tire, at which point the interlocking bosses and tabs resist further movement of the outer rim portion. The outer rim portion is thereby resisted from becoming a potentially dangerous projectile. A method of safely deflating the tire upon improper disassembly of the multi-piece safety wheel is also provided.

Abstract: An improved, multi-functional, portable, electronic climate control device to maintain personal body temperature at a desired level in relationship to different environments. The portable electronic control device can combine a refrigeration system with a circulation pump in fluid communication with a garment-like vest to provide personal cooling below surrounding ambient temperature, or include an electronic heating element with circulating pump in fluid communication with a garment-like vest to maintain personal body temperature above surrounding environment.

Abstract: An improved method for the manufacture of a compact brush guide holder assembly which is commonly found on machines in which electricity is to be transferred between an electrically conductive brush element as it moves and makes contact with a rotatable conductor such as a commutator. The brush holder assembly constructed of material that reduces antifrictional forces having a guiding channel or chamber defined by upper and lower curvilinear surface for supporting the electrically conductive brush element which receives compressed tension from a fixed non-removable constant force spring which is composed of a beam uncoiled section in addition to a coiled section having integrally fixed mounted Teflon bushings that are free to ride and float horizontally and vertically on mounting post that pass through its center.

Abstract: An improved method for the manufacture of a compact brush guide holder assembly which is commonly found on machines in which electricity is to be transferred between an electrically conductive brush element as it moves and makes contact with a rotatable conductor such as a commutator. The brush holder assembly has an open body guiding channel, or chamber, for supporting the electrically conductive brush element which receives compressed tension from a fixed non-removable constant force spring which is composed of a beam uncoiled section in addition to a coiled section having fixed mounted Teflon bushings that are free to ride and float horizontally and vertically on mounting post that pass through its center. Upon compression, the contour structural integrity and memory characteristics of the constant force spring are maintained as it self adjusts to the dynamic loads and tension requirements of a rush as it biases a commutator.
