    Abstract: A cryocooler is described that can include a pressure wave generator, and a refrigeration device (for example, a coldhead), which can be used to liquefy a gas when the gas is exposed to a surface of the refrigeration device. The pressure wave generator can include one or more motors. Each motor can include a stator, and at least one electrical coil wound around a portion of the stator. The electrical coil can generate a reversing magnetic field when alternating electric current is passed through the electrical coil. The motor can further include a pressurized container that can be placed within the space enclosed by the stator, and a piston that can be placed inside the pressurized container. The stators can be placed external to the pressurized container. The piston is made by combining magnets that have opposite and transverse polarities, and are combined adjacently on a common reciprocating axis.

    Abstract: A tank is configured to store a supply of cryogenic liquid and a heat exchanger has a main line and a reheat line. A liquid pickup line directs cryogenic liquid from the tank to the main line of the heat exchanger. A trim heater exit tee receives fluid from the main line of the heat exchanger. Fluid exits the trim heater exit tee through an engine outlet and a trim heater outlet. Fluid exiting through the engine outlet flows through a flow restriction device and to a primary inlet of a trim heater return tee. A trim heater line receives fluid from the trim heater outlet of the trim heater exit tee and directs it to the reheat line of the heat exchanger after the fluid passes through a portion of the trim heater line positioned within the tank. Warmed fluid leaving the reheat line of the heat exchanger travels to a trim heater inlet of the trim heater return tee.

    Abstract: A cryogenic fluid delivery system includes a main tank system with a main tank adapted to contain a first supply of cryogenic liquid, and reserve tank system with reserve tank adapted to contain a second supply of cryogenic liquid. A pressure building circuit is adapted to delivery vapor to the head space of the main tank to build pressure in the main tank and a fuel delivery line supplies cryogenic fuel from either the main tank or the reserve tank to a use device. The reserve tank stores saturated cryogenic fuel that is delivered to the use device via the fuel delivery line while the cryogenic liquid in the main tank is being saturated. The fluid delivery system automatically switches to delivering cryogenic fuel from the main tank to the use device via the fuel delivery line upon saturation of the cryogenic liquid in the main tank.

    Abstract: A dental charting system and method of generating a dental chart are provided. The dental charting system comprises a display unit, an input unit and an output unit. The display unit is configured to display a quadrant view of a set of teeth. The quadrant view comprises a quadrant subset of the set of teeth, and at least one of a diagnosis field and a procedure field for each tooth in the quadrant subset. Each tooth in the quadrant subset displayed having a crown, a root and an outline. The input unit is configured to receive an input for at least one of the diagnosis field and the procedure field for at least one tooth in the quadrant set of teeth. The output unit is configured to generate a dental chart displaying the set of teeth. Each tooth in the set of teeth displayed in a color associated with the received input for at least one of the diagnosis field and the procedure field. The method comprises displaying a quadrant view of a set of teeth, receiving an input for at least one of the diagnosis field and the procedure field for at least one tooth in the quadrant set of teeth, and generating a dental chart displaying the set of teeth.

    Abstract: An integrated cryogenic fluid delivery system includes a tank adapted to hold a supply of cryogenic liquid and having an end wall. A shroud is positioned on the end wall and contains a shell and tube heat exchanger. The heat exchanger includes a shell defining a warming fluid chamber and having a shell inlet and a shell outlet in fluid communication with the warming fluid chamber. A number of cryogenic fluid coils are positioned within the warming fluid chamber and are in fluid communication with a cryogenic fluid inlet port and a cryogenic fluid outlet port. A fuel shutoff valve has an inlet in fluid communication with a liquid side of the tank and an outlet in fluid communication with the cryogenic fluid inlet port of the heat exchanger. A manual vent valve has an inlet in fluid communication with a headspace of the tank and an outlet. The fuel shutoff valve and the manual vent valve each have a control knob that is accessible from the first or second side of the shroud.
