Abstract: A battery powers the motor of an electrically powered impact gun. The body of the gun vibrates at some frequency and an aluminum brush holder therein is configured to vibrate at about the same frequency to minimize chatter and arcing of the brushes on the commutator bars.

Abstract: To prevent the head of small sized bolts from being twisted off by a rotary electrically powered impact tool, a structure is provided between the outlet drive of the impact tool and the head of the bolt to minimize the torque transmitted between the impact tool and the bolt head.

Abstract: A windshield attachment for a golf cart or the like comprising an upper panel hinged to a lower panel at a horizontal hinge for movement from upright closed position to a lower dependent open position. The lower panel is provided with vertically spaced crossbars of tubular type with slotted ends. Clamping units fit over the posts and extend into the crossbar slots in interlocking relationship with the bars to hold them in selected horizontal positions at the respective levels. A similar top crossbar is similarly mounted on the posts at an upper level to engage the edge of the top panel when closed.

Abstract: A disposable article for interim cleaning of hard surfaces comprises a non-woven substrate, carrying an aqueous cleaning composition loaded onto the substrate at a level less than about 85%, preferably less than 75%, of its absorbence capacity. The aqueous composition comprises: optionally, one or more nonionic surfactants, one or more anionic surfactants or mixture of nonionic and anionic surfactants; a water miscible solvent for oils, (preferably a low molecular weight alcohol or N-methyl-2-pyrrolidone); and an alkalinity agent, such as ammonium hydroxide, in sufficient amount to maintain the pH of the extracted solution within the range of 8 to 12. The non-woven substance is preferably a non-chemically bonded fibrous material.

Abstract: Apparatus for washing an article, especially an automobile, comprises an article through which the article can pass, nozzles mounted on the framework, a tank provided with means for maintaining pressure therein and connected to the nozzles, a valve for controlling the flow of liquid from the tank to the nozzles and a timer. Upon actuation, the timer opens the valve for a predetermined interval, thereby allowing liquid to flow from the nozzles and wash the article passing through the framework. The pressure within the tank ensures that at least a predetermined quantity of liquid is sprayed during the interval fixed by the timer, even if the pressure in a water main supplying the apparatus fluctuates.

Abstract: A disposable article for light cleaning of hard surfaces comprises a non-woven substrate, preferably of cellulosic or cellulose-containing material, carrying an aqueous cleaning composition loaded onto the substrate at a level less than about 75%, preferably less than 50%, of its maximum absorbence capacity. The aqueous composition comprises one or more nonionic surfactants, one or more anionic surfactnats or a mixture of nonionic and anionic surfactants, a water miscible solvent for oils, (preferably a low molecular weight alcohol), and an alkalinity agent such as ammonium hydroxide in sufficient amount to maintain the pH of the extracted solution within the range of 8 to 12.

Abstract: An apparatus for controlling the operation of a door provided with a door closer comprises a body of ferromagnetic material mounted on a portion of a building adjacent the door, an electromagnet mounted on the door (the positions of the electromagnet and body may be reversed), a power supply, an actuator and a timer which connects the electromagnet to the power supply upon actuation by the actuator and disconnects the electromagnet from the power supply after a predetermined interval, thereby allowing the door closer to close the door.
