A print liquid supply sub-assembly, the print liquid supply sub-assembly to connect to a printer to provide a print liquid to the printer may include a print liquid output to connect to a print liquid input of the printer; a first fluidic channel upstream of the print liquid output comprising a first fluidic valve to prevent the print liquid from entering a supply container upstream of the first fluidic valve; and a second fluidic channel upstream of the print liquid output fluidically coupled to the first fluidic channel comprising a second fluidic valve to selectively prevent the fluid from passing out of the supply container downstream from the second fluidic valve.

Fluidic valves formed in a sub-assembly

A fluidic interface may include a fluidic needle of a first polymer based compound and a body wall that is to support the fluidic needle, the body wall of a second polymer based compound, different than the first polymer based compound.

Fluidic interface

Fluidic dispense device

An apparatus for enhancing fuel mileage of internal combustion engine consists of a tube inserted into a fuel line between a fuel storage tank and the engine, the tube having a plurality of electrodes protruding into a fuel passage within the tube. The electrodes are provided with an electrical charge for imparting electrical charges to liquid fuel molecules flowing through the fuel passage of the tube.

Fuel savings device and methods of making the same

A first reservoir member of an ink cartridge reservoir, the first reservoir member including a first portion formed of a thermoplastic that is one of absorbent of and transparent to radiant thermal energy, and configured to be welded to a second reservoir member, and a second portion formed of a thermoplastic having a characteristic different than the first portion.

Ink cartridge reservoir

A method and apparatus to increase the fuel economy of a diesel engine having an injection system fuel rail by increasing the flow rate of fuel being returned to the tank hence decreasing the temperature of the fuel returned to the tank from the fuel rail while maintaining a given pressure at the fuel rail.
