A dual-levered faucet assembly which allows user to reduce water usage by 50% when needed while operating the faucet in habitual preferred manner of using swift single motion of hand. When any one lever is operated in this manner, the water outflow is 50% of a conventional single-levered faucet. When both levers are operated in this manner, water outflow is same as that of a conventional single-levered faucet.

A water tap body has a mechanical mixing valve which is operable selectively to allow water to flow only from a first water inlet to a water outlet of the mixing valve, to allow water to flow only from a second water inlet to the water outlet, and to allow a mix of water to flow to the water outlet. The water tap body also has a mechanical selector valve which is operable selectively to allow water to flow only from a first water inlet to a water outlet and to allow water to flow only from a second water inlet to the water outlet of the mechanical selector valve. The water outlet of the mechanical mixing valve is in fluid communication with a first tap body outlet. The water outlet of the mechanical selector valve is in fluid communication with a second tap body outlet.

Provided herein are processes for preparing estolides and estolide base oils from fatty acid reactants utilizing catalysts. Further provided herein are processes for preparing carboxylic esters from at least one carboxylic acid reactant and at least one olefin.

Disclosed is a rotary valve 1 comprising a stator 20 and a rotor 40 generally in rotary sliding engagement with the said stator about a valve axis RA, the stator including a plurality of fluid ports 22, 26, 28, the rotor 40 being operable to selectively fluidically interconnect two or more of said ports during its rotary sliding engagement. The valve further includes an actuator (70) for disengagement of the rotor from the stator to enable efficient cleaning of the valve interconnections.

The present disclosure relates generally to a faucet valve cartridge configured for use within a dual handle faucet. The valve cartridge includes an upper plate and a bottom plate received within a valve housing and configured to control fluid flow from an inlet to an outlet. The valve may include anti-water hammer port geometry to reduce turbulent flow and shut-off shock wave noise.

A component for a faucet includes a substrate including alumina and a first material provided over at least a portion of the substrate. The first material includes titanium and carbon. The component also includes a second material provided over the first material, the second material including carbon and having carbon sp3 bonding of at least 40 percent.

A dispensing valve for fastening to a water faucet disposed over a drain and to a reverse osmosis water filtering unit for controllably dispensing tap water, for providing feed water to the reverse osmosis water filtering unit, for providing squeeze water to the reverse osmosis water filtering unit and dispensing product water received therefrom, and to block all water flow. The dispensing valve may also dispense tap water in a spray, and provide for waste water disposal.

A method and apparatus for compressing gases and supplying compressed gaseous fuel to a consuming device, such as a gaseous fueled vehicle or the like. One embodiment includes a gas compressor for compressing the gaseous fuel to an array of tanks having predetermined initial set points which are increasing for tanks in the array. One embodiment provides a selecting valve having first and second families of ports wherein the valve can be operated to select a plurality of ports from the first family to be fluidly connected with a plurality of ports with the second family, and such fluid connections can be changed by operation of the valve.
