摘要:
A sprayer attachment for a hand-supported power tool comprises a motion converting mechanism, a pumping mechanism, a spray assembly and a housing. The motion converting mechanism has an input shaft. The pumping mechanism is driven by the motion converting mechanism. The spray assembly is fluidly coupled to the pumping mechanism. The housing assembly couples the motion converting mechanism, the pumping mechanism and the spray assembly. The sprayer attachment may further comprise an anti-rotation bracket extending from the housing. The sprayer attachment may further be coupled to a handheld power tool, such as a cordless drill or a reciprocating saw, with the anti-rotation bracket.

A valve having a membrane for controlling flow through the valve, the membrane having open and closed positions. An element urges the membrane to the closed position, and a vacuum pressure at one end of the valve may overcome the urging of the element, thereby moving the membrane to the open position. An actuator is provided for easing or initiating the movement of the membrane. In some embodiments, the valve may take the form of a valve assembly for use in a variety of applications, for example, a valve assembly for relieving a vacuum pressure wherein the assembly includes intake and exhaust ends, a membrane for controlling flow through the assembly, a spring providing a closing bias to the membrane that the vacuum pressure may overcome to move the membrane, and an actuator for initiating the movement of the membrane.

A soap dispenser can be configured to dispense an amount of liquid soap, for example, upon detecting the presence of an object. Certain embodiments of the dispenser include a housing, reservoir, pump, and nozzle. In some embodiments, the dispenser includes a bypass passage, which can facilitate priming of the pump. In certain embodiments, the dispenser is configured to inhibit or avoid the formation of an air bubble that could obstruct the liquid soap from entering the pump. In some embodiments, the pump includes engaging gears, which can include a plurality of teeth with substantially pointed tips. In certain embodiments, the nozzle comprises a one-way valve, such as a duckbill valve. Some embodiments of the one-way valve are shaped or otherwise configured to provide certain biases to the valve, which can, for example, facilitate rapid opening and closing of the valve.

An apparatus for providing cooling to a user comprises a bag, an input hose, an output hose, one or more discharge extensions, and a pump. The bag is operative to store a liquid. The one or more discharge extensions are in fluidic communication with the output hose, and each of the one or more discharge extensions terminates in a respective one of one or more nozzles. Lastly, the pump is operative to draw the liquid from the bag via the input hose and to expel the liquid into the output hose so as to cause the liquid to flow to the one or more discharge extensions and to be expelled through the one or more nozzles in the form of a water mist.

The present invention relates to a composition having a pH of less than about 7, for treating a hard surface comprising: at least one low residue surfactant and/or an alkyl ethoxylate surfactant; and a polymeric biguanide.
摘要:
The present invention provides preferred, preferably liquid, hard surface cleaning compositions, compositions with cleaning liquid composition on a substrate, compositions used with absorbent pads and implements and devices for making the process of cleaning hard surfaces and/or maintaining their appearance and hygiene easier and more effective. These compositions, along with specific instructions for use are advantageous for removal of and/or prevention of buildup of soils commonly encountered on floors, glass surfaces, counters, walls, showers and/or tubs, said compositions comprising hydrophilic polymers to render the cleaned surface hydrophilic and to improve the appearance when the surface is either not rinsed, or when the composition is incompletely removed, specific surfactant, preferably surfactant selected to minimize spotting/filming, optionally specific organic cleaning solvents to provide cleaning and wetting particularly in applications where levels of non-volatiles need to be minimized, and, optionally, anti-bacterial agents for preserving or surface activity and optionally perfumes for aesthetics.
摘要:
Antimicrobial, hard surface cleaning compositions that effectively clean and reduce microorganisms on a surface without resulting in unacceptable filming and/or streaking residue on the surface, generally comprise (a) cationic antimicrobial active; (b) nitrogen-containing polymer; and (c) surfactant. Preferred antimicrobial, hard surface cleaning compositions for use in no-rinse cleaning methods comprise (a) from about 0.001% to about 0.5%, by weight of the composition, of surfactant; (b) cationic antimicrobial active; and (c) nitrogen-containing polymer. Methods of cleaning and reducing microorganisms on hard surfaces comprises contacting the surfaces with such compositions and preferably allowing the compositions to dry on the surface without rinsing the composition from the surface using water or other rinsing solution.
