Abstract: An automatic window cleaning apparatus for use with windows on buildings is disclosed. The apparatus would be an electronic system for automatically cleaning the exterior side of windows in buildings, preferably skyscrapers, which would be operated through a control panel located inside a room within the building. Each system would be specifically designed for only one window.

Abstract: Mirror cleaning devices clean the external mirrors of large vehicles while they are being driven. During adverse weather conditions, the external mirrors of large vehicles can become occluded by rain, snow, or dirt. By keeping the mirror glass clean and moisture free, the driver is able to easily use the mirror without having to frequently pull to the roadside to clean moisture and dirt from the mirrors with a rag. The driver is able to maintain a full view to the rear sides at all times for safe passing, lane changing, merging, and reversing regardless of the weather conditions present.

Abstract: A reciprocating linear sweeping wiping mechanism includes a guide and drive carriage bearing at least a wiper element slidingly mounted inside at least a rigid longitudinal guide rail produced in the form of a hollow extruded profile. The transverse positioning of the frame plate relative to the extruded profile includes a longitudinally oriented rigid rib borne by the extruded profile or by a frame plate, which is received longitudinally sliding in a vertically open matching longitudinal groove borne by the frame plate or the extruded profile, respectively, and each stabilizing element is a stabilizing pad which is longitudinally slidingly received inside the corresponding C-shaped slide rail.

Abstract: A mirror housing contains an electrical motor. A drive arm is mounted to the output shaft of a speed reducer mounted on the motor. A linkage arm rotatably couples the drive arm to a rocker disk which is rotatably mounted within the housing.

Abstract: A laterally movable wiper arm assembly cleans curved interior surfaces of automobile and truck windshields. The wiper blade is movable on two curved tracks; one at the top of the windshield and one at the bottom of the windshield, with a vertically oriented telescoping wiper blade movable laterally therebetween. The telescoping arm support permits the vertical blade to tilt into the corners at the bottom of the windshield, to cover a larger proportion of the area, since the bottom of a windshield is longer than the top. The blade or wiping pad is supported with a resilient foam layer attached to a flexible substrate, which is adjustably attached to a rigid support arm following the windshield contour.
