Abstract: The present invention relates generally to a smoke removal apparatus. More specifically, but not in the way of limitation, an apparatus configured to be secured to a window frame of a structure wherein the apparatus is operable to provide isolation of smoke or similar, inhibit propagation thereof into the interior volume of a room, and expel said smoke or similar to an external environment. The present invention includes an interior window frame, at least two arms secured to said window frame, a foldable material operably disposed intermediate the at least two arms and coupled thereto, and at least one exhaust fan configured to draw air towards said window, wherein said exhaust fan expels said smoke or similar to an external environment.

Abstract: The present invention is an all-in-one pavement cutting and debris removal system, which comprises a cutting assembly including a saw blade and motor for supporting and rotating the saw blade, a water supply assembly that sends water to the saw blade including a water tank and water tube to keep the saw blade cool during cutting, and an assembly for removing the cutting debris/slurry created during the cutting. The assembly may utilize a high-pressure air flow or water to blow away the cement/water debris or a high vacuum suction device to vacuum away the cement/water debris. The present system employs a single truck to carry or tow the cutting assembly, water tank and air compressor for the same function that currently requires two trucks.

Abstract: A specially designed line marking device includes a marking string that is attached to a bow-shaped support structure with no free end for conveniently use by a single operator, a shuttle for coating the marking string with marking media prior to use, allowing an operator to effectively use this marking device and snap a marking line onto a working surface without the assistance of an additional operator, and a movable carriage containing liquid, powder, or aerosol marking media to be sprayed or deposited along said marking string, creating an inverse image of the marking string.
