Apparatuses, systems, and methods are disclosed for eliminating or greatly reducing the cleaning process of frozen confection apparatus or machines by having the comestible mixture contained in a flexible container or bag. The comestible mixture is chilled and/or frozen and dispensed from the bag without contacting other parts of the machine, thereby helping to prevent the comestible mixture from being contaminated with bacterial, viral, chemical, or physical contaminants.

Systems and methods have demonstrated the capability of rapidly cooling the contents of pods containing the ingredients for food and drinks.

Disclosed are devices, systems, and methods, including an oxygen delivery device that includes an oxygen delivery module to produce at least concentrated oxygen, and a gas moving device to deliver air to the oxygen delivery module. The gas moving device includes at least one piston rotatable inside a first chamber defined in a housing, the rotational movement of the at least one piston inside the first chamber resulting in varying pressure generated in a first portion of the first chamber, and a vane member rigidly coupled to the at least one piston, the vane member being configured to move inside a vane chamber defined in the housing, the piston and the vane rigidly coupled to the piston define the first portion of the first chamber and a second portion of the first chamber.

Portable oxygen delivery device

The present disclosure relates to improvements to thermodynamic devices that approximate the Ericsson cycle, Brayton cycle, or regenerated Brayton cycle. These cycles and various ways of implementing them are known in the art. They can operate as engines or refrigerators. The Ericsson cycle is attractive since it can theoretically operate at the Carnot efficiency, which is the maximum possible efficiency for a heat engine or refrigerator.

Ericsson cycle device improvements

Rotary systems are described, which can include at least one of compressors and vacuum pumps. Each rotary system includes a corresponding piston that rotates in an orbital motion around a respective eccentric of a shaft in order to either compress fluid or function as a vacuum pump. Multiple rotary systems can be executed on parallel on a single shaft such that these rotary systems are powered by a single motor. Various components of the rotary systems are coated with an abradable coating, which minimizes friction when these components come in contact with each other. The minimized friction minimizes the wear and tear of these components. Each rotary system can be lubricated by only the fluid being processed (for example, compressed or vacuumed) by that rotary system. The use of the fluid being processed for lubrication and the abradable coatings eliminate a need for another lubricant for lubricating the rotary system.

Rotary systems lubricated by fluid being processed

An aspect of the present disclosure involves a rotary compressor that is primarily optimized for use without the need for liquid lubricants, such as in the flow path of the fluid being compressed, and is efficient and quiet to use. The compressors described herein are efficient, run quietly, use less power, and last longer than those previously known in the art. The compressors are useful for medical applications and other clean gas applications, for instance, where lubricants could contaminate the fluid being compressed and/or increased noise and/or vibration may be problematic.

Rotary compressor

A thermodynamic system that can approximate the Ericsson or Brayton cycles and operated in reverse or forward modes to implement a cooler or engine, respectively. The thermodynamic system includes a device for compressing a first fluid stream containing a first gas-liquid mixture having a sufficient liquid content so that compression of the gas within the first gas-liquid mixture by the compressing device is nearly isothermal, and a device for expanding a second fluid stream containing a second gas-liquid mixture having a sufficient liquid content so that expansion of the gas within the second gas-liquid mixture by the expanding device is nearly isothermal. A heat sink is in thermal communication with at least the liquid of the first gas-liquid mixture for transferring heat therefrom, and a heat source is in thermal communication with at least the liquid of the second gas-liquid mixture for transferring heat thereto. A device is provided for transferring heat between at least the gas of the first gas-liquid mixture after the first fluid stream exits the compressing device and at least the gas of the second gas-liquid mixture after the second fluid stream exits the expanding device. The compressing and expanding devices are not liquid-ring compressors or expanders, but instead are devices that tolerate liquid flooding, such as scroll-type compressors and expanders.

Thermodynamic systems operating with near-isothermal compression and expansion cycles

A scroll compressor has lubricant flow which communicates lubricant onto a motor protector when adverse conditions are present causing the motor protector to trip the motor and stop further rotation. The lubricant is returned to an oil sump through a normal return path. The normal return path outlet may be positioned above the motor protector such that lubricant will contact the motor protector when adverse conditions are present, or the outlet may be remote from the protector. When the outlet is remote from the protector, a funnel and tubing divert the oil to the motor protector under adverse conditions. Alternatively, a passage communicating with the normal return path is selectively blocked when an adverse condition is present. At that time, lubricant is forced into an alternative oil path, which is positioned above the motor protector.
