Abstract: A system for dispensing a cryogenic fluid includes a bulk storage tank configured to contain a supply of the cryogenic fluid. A heat exchanger coil is positioned in the headspace of at least one intermediate fluid tank, which contains an intermediate fluid, and is configured to receive and warm a cryogenic fluid from the bulk storage tank via heat exchange with intermediate fluid vapor in the headspace. A buffer tank receives fluid from the heat exchanger coil. A chiller coil is positioned within the intermediate fluid tank and is submerged within intermediate fluid liquid contained within the at least one intermediate fluid tank. The chiller coil receives fluid from the buffer tank and cools it via heat exchange with intermediate fluid liquid within which the chiller coil is submerged for dispensing.

Abstract: A system for cryogenic gas delivery includes a cryogenic tank configured to contain a cryogenic liquid and a gas within a headspace above the cryogenic liquid. The system also includes first and second vaporizers and a use outlet. A first pipe is configured to transfer gas from the headspace through the first vaporizer to the use outlet. A second pipe is configured to transfer liquid from the tank through the first vaporizer so that a first vapor stream is directed to the use outlet. A third pipe is configured to build pressure within the tank by transferring liquid from the tank through the second vaporizer so that a second vapor stream is directed back to the headspace of the tank. A first regulator valve is in fluid communication with the second pipe and opens when a pressure on an outlet side of the first regulator drops below a first predetermined pressure level. A second regulator valve is in fluid communication with the third pipe and opens when a pressure inside the tank drops below a second predetermined pressure level. The first predetermined pressure level is higher than the second predetermined pressure level.

Abstract: A cryogenic liquid dispensing system having a tank that holds cryogenic liquid and a basin configured to hold cryogenic liquid at a height above a bottom portion of the tank. The system is configured to pump cryogenic liquid for dispensing from the bottom portion of the tank when the cryogenic liquid in the tank is of a sufficient level to provide an adequate liquid head to permit pump operation, and is configured to pump cryogenic liquid for dispensing from the basin when the liquid in the tank is of an insufficient level to provide an adequate liquid head to permit pump operation to dispense cryogenic liquid.

Abstract: A configurable cryogenic storage device has a freezer and a rack carrier positioned inside of the freezer. The freezer includes a bearing and a drive shaft though the freezer, the drive shaft being coupled to the rack carrier inside the freezer and adapted to be coupled to a motor assembly. The rack carrier rests on the bearing in a manual rotation configuration and hangs from the drive shaft when the motor is connected. Coupling the drive shaft to the motor assembly lifts the rack carrier and decouples the bearing and enables automated rotation of the rack carrier by the motor. The rack carrier includes rack-mounting features holding a plurality of sample storage racks. The sample storage racks hang from the rack carrier and the rack-mounting features precisely position the end of each sample storage rack.

Abstract: A doser for dispensing a cryogenic fluid includes a doser body configured to receive the cryogenic fluid. The dosing arm has a proximal end and a distal end and a central passage extending between the proximal and distal ends. Furthermore, the dosing arm is configured to receive cryogenic fluid from the doser body. A bayonet connection removably connects the proximal end of the dosing arm to the doser body. A dosing head is mounted to the distal end of the dosing arm and is configured to receive cryogenic fluid from the central passage of the dosing arm and to dispense the cryogenic fluid.

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: A cryogenic freezer features a dewar defining a storage space. A reservoir is positioned within or adjacent to the storage space and is configured to contain a cryogenic liquid with a headspace above the cryogenic liquid in a reservoir interior space that is sealed with respect to the storage space. A refrigeration module is in heat exchange relationship with the reservoir. A sensor is configured to determine a temperature or pressure within the reservoir. A system controller is connected to the sensor and the refrigeration module and configured so that the refrigeration module is adjusted to provide additional cooling to the reservoir when a pressure or temperature within the headspace increases.

Abstract: A cryocooler is described that can include a pressure wave generator, and a refrigeration device (for example, a cold-head), 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 device combines a muffler and a filter such as for use with an air compressor. The device utilizes dual expansion chambers with an internal connecting tube to filter the air entering an air intake port of an air compressor or oxygen concentrator. The device attenuates sound that emanates from airflow through the chambers.
