Variable flow rate fuel ejectors, and methods of use therefore, are disclosed. One variable flow rate ejector includes a primary nozzle, a needle, a motor, a first stop portion, and a first impact-absorbing portion. The primary nozzle is connected to a first inlet chamber to receive a first fluid and transmit a flow of the first fluid through the primary nozzle opening. The needle is disposed to create a gap between the tapered portion of the needle and the primary nozzle opening. The motor is coupled to axially move the needle to vary a size of the gap. The first stop portion delimits the axial movement of the needle in a direction of retraction of the needle from the primary nozzle opening. The first impact-absorbing element is positioned to contact the first stop portion or the needle, respectively, when the needle is fully retracted from the primary nozzle opening.

Devices, systems, and methods for variable flow rate fuel ejection

Devices, systems, and methods for variable flow rate fuel ejection are disclosed. A variable flow rate ejector comprises primary and secondary inlets, primary and secondary nozzles, and a needle. The primary nozzle is connected to receive a first fluid from the first inlet chamber and transmit the first fluid through a primary nozzle opening. The needle is disposed within the primary nozzle opening and is axially movable to vary an area of primary nozzle opening. The primary nozzle opening and the needle are sized to make the flow of the first fluid have a supersonic speed. The secondary inlet opens into a second inlet chamber positioned outside the primary nozzle opening. A portion of the second fluid is entrained in the flow of the first fluid from the primary nozzle. The secondary nozzle opening is sized to make the flow of the first and second fluids have a subsonic speed.

A lithium ion battery is provided which contains a cathode, an anode, an electrolyte and a separator, wherein the anode employs polythiocyanogen as an active material.

The present invention relates to novel methods for producing a nano-porous gas diffusion media, compositions thereof, and devices comprising the same. The nano-porous gas diffusion media of the invention is produced using photolithographic techniques to create a solid substrate comprising a plurality of nano-scale (1 nm-300 &#x3bc;m) pores or holes that allow for the diffusion or exchange of molecules, gases, and/or liquids through the substrate. The nano-porous diffusion media of the invention also displays superior electro- and thermal conductivity, and increased durability and performance. In some embodiments, the nano-porous diffusion media of the invention is also coated with a self-assembling monolayer (SAM) of organic molecules to further improve its physical characteristics.

A mixing vessel contains a septum, dividing a first chamber from a second chamber. By relatively moving the septum with respect to the ends of the vessel, and flowing a fluid through the septum, the fluid is treated as it moves from the first chamber to the second chamber. The particular configuration of the septum allows for treatments such as mixing, reacting, heating, and cooling, as well as filtering of the fluid.

A disposable flexible vessel contains a septum, dividing a first chamber from a second chamber. By flowing a fluid through the septum, the fluid is treated as it moves from the first chamber to the second chamber. The particular configuration of the septum allows for treatments such as mixing, reacting, heating, and cooling, as well as filtering of the fluid.

An apparatus to visually and electronically observe the transient temperature changes in a heat-conducting body, and a method for teaching heat conduction to students incorporating the apparatus. The apparatus includes a heat-conducting body, and a pair of electric strip heaters attached to adjacent sides of the heat-conducting body for conducting heat therethrough. A pair of heat exchangers are attached to sides of the heat-conducting body that are opposite to the sides the electric strip heaters are attached to. A thermochromic liquid crystal sheet is provided on a top surface of the heat-conducting body and displays the transient heat conduction through the heat-conducting body. An insulating plate is located above the top surface of the heat-conducting body to create a gap between the thermochromic liquid crystal sheet and the insulating plate. A plurality of thermocouples are attached to a bottom surface of the heat-conducting body for measuring the transient heat conduction within the heat-conducting body.
