Abstract: A cleaning assembly includes a handle assembly configured to grasp a moistened tissue. A drum is included within a dispensing unit to store the tissue. The dispensing unit selectively releases the tissue from the drum as an actuating assembly operates a lever between a first position and a second position. The drum is seated within the dispensing unit in communication with the actuating assembly in a manner such that the tissues are sealed and prevented from drying out. The seal is selectively broken to permit dispensing of the tissues. The cleaning assembly permits a user the ability to clean a potentially unclean surface without the need to physically contact any of the cleaning tissue, chemicals, or surface itself at any time. The user is separated from the potentially harmful surfaces and chemicals.

Abstract: A lightweight winch suitable for industrial applications has the motor assembly self-centered with a housing within the winch drum where it may be easily accessed and removed from the winch drum. The winch drum is supported by a bearing means capable of bearing heavy loads in addition to contributing to a compact profile of the winch. The winch comprises an improved, non-load bearing levelwind mechanism for evenly winding cable about the winch drum.

Abstract: A device for securing an end of a braided hoisting rope to a lifting device includes a tubular fastening frame to be fixed to the lifting device; and a coil spring which is arranged to be installed and fastened over the tubular fastening frame.
