Also provided are fabrics formed from the textile fibers, protective gear and articles of clothing made from the fabrics, and methods of using the fibers and fabrics to catalyze the hydrolysis of organic molecules, such as organophosphate-based nerve agents, having hydrolysable bonds.

An apparatus includes a housing with an inlet for a pasty product to be aerated and an outlet for the aerated product. The apparatus includes at least a first set of a rotor and a stator and a second set of a rotor and a stator. The apparatus further includes a gas injector for injecting, upstream of the first set of the rotor and the stator, a gas into the pasty product to be aerated. The apparatus further includes an intermediate mixing chamber provided in the housing between the first and the second sets of the rotor and the stator . A secondary product introduction member protrudes into the intermediate mixing chamber so as to issue into the intermediate mixing chamber. A method for aerating a pasty product is also provided.

A gas-saturated liquid generator having a vessel of the generator, a hollow bell in its upside down position located with a tube for gas supply, and a mixer situated in the area for saturated liquid covered by the bell is disclosed. The entire bell is submerged below the surface of the saturated liquid. On a shaft projecting from a driving equipment, the mixer provided with a foaming spring is situated. The mixer provided with a magnetic carrier seated rotatably on the protrusion formed by a bulge in the bottom part of the generator vessel may be used. The preferred bell forms are dome-shaped, cylindrical or conical.

A portable foam brush assembly having a base having a soap supply, a water supply, and an electrical supply. A foam brush wand is detachably dockable to the base and in electrical and fluid communication with the foam brush wand having battery pack, a peristaltic pump, a reservoir chamber, a foaming chamber, an air pump, a brush and a momentary release switch. The base water supply and the base soap supply, when activated, are configured to travel by a water supply hose and a soap supply hose to a tee in the base where they are combined in a combined hose to a base quick coupler that is connectable to a reciprocal foam brush wand quick coupler, which has a foam brush wand hose to deliver the water soap mixture to bladder in the foam brush wand.

A portable foam brush includes a soap reservoir, such as optionally in a base or in a wand, a foaming chamber, and an air compressor, such as optionally battery-operated air compressor. The compressor is configured for supplying air to act upon the soap from the reservoir to cause dispensing of soap to the foaming chamber. In some embodiments, the compressor may also supply air to the foaming chamber. In use, the soap and the air in the foaming chamber combine to form an air and soap foam. The brush includes a brush end configured for receiving foam from the foaming chamber and dispensing the foam.

Electrically operated coffee machine, in particular espresso machine or fully automatic coffee machine, having a steam output device that can include a steam lance wherein the steam lance can include a milk inflow which is configured to supply milk into a steam output channel of the steam lance.

A device for loading an in particular higher-viscosity liquid, such as a silicon resin, for example, with air or another gas. The device has a pressure vessel receiving the liquid and the gas, in which pressure vessel an agitator, having a drive shaft set through the pressure vessel at least in part, is arranged. In order to enable the particularly fast and homogeneous intermixing of the liquid and gas, the drive shaft is arranged in a conveying pipe and drives a conveying organ, in particular a screw conveyor, which transports the liquid through the conveying pipe to at least one outlet, and there is an running-off surface underneath the outlet from the conveying pipe for the liquid flowing out of the outlet. Upon actuation of the agitator, the liquid is thus not only well intermixed together with the air already received therein, but at the same time conveyed through the conveying pipe to the running-off surface, on which it can discharge in a thin layer and has a particularly large exchange area with the gas as a result.

A mixing apparatus is described. The mixing apparatus has a first port for receiving milk, a second port for receiving steam, and a mixing chamber for mixing the milk, the steam, and air. A channel arrangement connects the first port and the second port, and defines an air intake channel which leads to a frothing section. The mixing apparatus is designed such that, in use, the frothing section fills sufficiently with steamed milk that has a direct path from the second port to the mixing chamber is interrupted by the steamed milk. This provides a noise reduction during use of the mixing apparatus. A flow reducing means, such as a barrier, may be used for this purpose.

An exemplary foam-at-a-distance soap or sanitizer dispenser includes a housing, a container for holding a foamable liquid, and a pump in fluid communication with the container. The pump has a pump chamber air inlet, a pump chamber air inlet valve, a pump chamber air outlet, a pump chamber air outlet valve, a pump chamber liquid inlet, a liquid chamber liquid inlet valve, a pump chamber liquid outlet, and a pump chamber liquid outlet valve. The exemplary dispenser further includes an air conduit extending from the pump chamber air outlet to a remote mixing chamber and a liquid conduit extending from the pump chamber liquid outlet to the remote mixing chamber. The remote mixing chamber is located at a distance from the pump chamber air outlet valve and the pump chamber liquid outlet valve and that distance is greater than about 3 inches. A one-way liquid check valve is located proximate the mixing chamber, one or more mix media located downstream of the mixing chamber and an outlet nozzle located proximate the mixing chamber.

An apparatus that produces and dispenses foam comprises a housing, an adjustable water flow member, an adjustable foam concentrate flow member, a first mixing chamber comprising an outlet, a water pressure reducing member with a portion thereof disposed within the first mixing chamber, a second mixing chamber in a communication with the outlet from the first mixing chamber, an air pressure reducing member with a portion thereof disposed within the second mixing chamber, a third mixing chamber in a communication with an outlet from the second mixing chamber, the third mixing chamber comprising a port in a communication with an external environment to the housing, and a screen member disposed within the third mixing chamber and configured to convert a mixture of air, water and foam concentrate exiting the outlet of the second mixing chamber into the foam, the foam being dispersed through the port during operation of the apparatus.
