Abstract: An imaging system (12) for a printing press (10) having an imaging cylinder (44) having an outer surface (46) mobile to movement of charged particles, a device (52) for inducing a charge on the surface of the cylinder (44) of a first polarity, a film (48), a device (50) for passing the film (48) over at least a portion of the outer surface (46) of the imaging cylinder (44), a device (53) for passing charged particles of a second opposite polarity in a pattern through the film (48) onto the outer surface (46) of the imaging cylinder (44), a device (56) for passing a charged particulate material of the second polarity opposite the first polarity onto the film (48) over the pattern information on the cylinder (44) to form an image (80) of the particulate material (58) on the film (48), a device (62) for bonding the particulate material (58) onto the film (48), a print cylinder (36 or 38) having an outer surface (66), and a device (70) for placing a segment of the film (48) over the outer surface (66) of the prin

Abstract: A trailer hitch comprising, a hitching ball for a vehicle having an annular groove below the ball, a hitching member for a trailer having a pair of spaced openings extending therethrough, an elongated U-bolt for passage through the openings and in the groove to retain the hitching member to the ball, and a device for clamping the U-bolt to the hitching member.

Abstract: A mobile boat comprising, a hull having a space, a pair of wheels on opposed sides and adjacent an upper portion of the hull for placement of the hull in an inverted configuration for transport, and a hitch for a vehicle adjacent a forward portion of the hull.

Abstract: A device for making and warming coffee comprising, a first reservoir for holding a liquid, a second reservoir for holding brewed coffee, a microwave heating device for heating the liquid or coffee, a device for selectively pumping the liquid or coffee from the respective reservoir into the microwave oven, a receptacle for holding coffee grounds, a container for holding liquid, and a device for selectively pumping the heated liquid or coffee from the microwave heating device into the receptacle or container.

Abstract: A container comprising, a sidewall defining a cavity, and a liner secured to the sidewall and being movable in the cavity between different positions in the container.

Abstract: An adjustable ladder comprising, a pair of side supports, a device for retaining the supports in a spaced relationship, a rung, a device for slidably mounting the rungs in the supports, and a device for moving the rung along the supports for adjusting the position of the rung.
