Abstract: A glass surface cleaning machine includes a supporting frame which has a fluid receiving chamber provided therein and includes a supporting arm frontwardly extended therefrom, a wiper blade transversely mounted on a front edge of the supporting arm of the supporting frame for wiping on a glass surface, and a vacuum device supported by the supporting frame. The vacuum device includes at least a fluid suction nozzle supported underneath the wiper blade and in communication with the fluid receiving chamber and an impeller to create a low pressure within the fluid receiving chamber with respect to the atmosphere pressure so as to create a sucking effect for removing fluid from the glass surface through the fluid suction nozzle and directing the fluid to deposit in the fluid receiving chamber.

Abstract: An automate glass surface cleaning machine includes a supporting frame which has a fluid receiving chamber provided therein and includes a supporting arm frontwardly extended therefrom, a wiper blade transversely mounted on a front edge of the supporting arm of the supporting frame for wiping on a glass surface, and a vacuum device supported by the supporting frame. The vacuum device includes at least a fluid suction nozzle supported underneath the wiper blade and in communication with the fluid receiving chamber and a motor powers an impeller to create a low pressure on one side of the impeller and a high pressure on the other side thereof so as to create a sucking effect for removing fluid from the glass surface through the fluid suction nozzle and directing the fluid to deposit in the fluid receiving chamber.

Abstract: A slide window and door lock includes a connecting device selectively mounted on a vertical jamb of a sliding panel at a predetermined height with respect to a base slider track of a supporting frame and a locker panel having one pivot edge pivotally connecting to the connecting device and another opposed locking edge adapted for inclinedly biasing against the base slider track at a predetermined angle so as to lock up the sliding panel in a slidably movable manner.
