A liquid container refill management system including a machine learning algorithm and method of training the same, the system and method making use of noninvasive tank-in-tank measuring techniques. The system can comprise of a container fill level indicator. The container fill level indicator can be capable of detecting a vibration response signal on the outer surface of a container, wherein the system is capable of transmitting the response signal to a remote data processor for processing using a trained machine learning algorithm. The trained machine learning algorithm can be trained by the process of selecting model inputs and outputs to define an internal structure of the machine learning algorithm, applying a collection of input and output data samples to train the machine learning algorithm, and verifying the accuracy of the machine learning algorithm by applying input data samples and comparing received output values with expected output values.

Improvements in machining systems that utilize machining fluids comprising a supercritical fluid are described. Some systems may provide centralized distribution of a supercritical machining fluid and/or a lubricant to a plurality of machining tools in a machining facility. Other systems may allow for selective delivery of multiple machining fluids to a machine tool. For example, a supercritical machining fluid and a non-supercritical machining fluid may be selectively delivered to a machining tool as desired for a particular machining process.

The invention relates to a tank container (100; 100) for the transport and storage of cryogenic liquefied gas, comprising a framework (120) and a cylindrical vessel (110) connected to the frames work (120), wherein the vessel (110) is covered by a superinsulation arrangement (130) based on an aerogel composition, and the vessel (110) is connected to the framework (120) by a clamping device (30) which is adapted to allow for a relative movement between the framework (120) and the vessel (110) due to thermal expansion or contraction of the vessel (110).

An object of the present invention is to provide a gas storage container that is easy to transport and install. The gas storage container according to the present invention has flat upper and lower surfaces and can be stacked vertically. The gas storage container according to the present invention may include a casing that has a flat upper surface and a flat lower surface and is vertically stackable, and a gas container installed in the casing.

Systems and methods related to loading and unloading stations for simultaneous unloading of a first fluid from at least one storage tank in a vessel and loading of a second fluid into a storage tank of the same vessel are provided. In at least one aspect, a loading and unloading station includes a first connector for fluid connection to a storage tank of the vessel for unloading the first fluid, and a source of the second fluid. The station also includes a second connector for fluidly connecting the source of the second fluid with a storage tank of the vessel for loading the second fluid. The station further includes a first thermal linkage between the first fluid being unloaded and the second fluid being loaded that facilitates heat transfer between the first fluid and the second fluid at the loading and unloading station.

Canisters are provided that include a cylindrical body and a cap welded to the body to define a cavity filled with carbon dioxide or other fluid. The canisters may be loaded into a medical device, e.g., to provide an energy source for operating the device. Methods for making such canisters are also provided.

A system delivers carbon dioxide to a facility having photosynthetic organisms, such as crops, plants, and trees. The system has a containment structure which houses a volume of liquid or solid carbon dioxide (dry ice). The containment structure has a containment structure inlet and a containment structure outlet. A gas source provides a fluid to the containment structure through the containment structure inlet. Upon entry into the containment structure, the gas or a saturated liquid encounters the solid or liquid carbon dioxide causing sublimation or evaporation, resulting in the formation of carbon dioxide gas or liquid which flows out of the containment structure through the containment structure outlet. The gas entering the containment structure may also have subcooled CO2 liquid or solid (snow), which replenishes the solid or liquid within the containment structure. To supplement evaporation or sublimation of the subcooled liquid or solid, heating means are used. A distribution line connected to the containment structure outlet delivers carbon dioxide gas or liquid which is flashed to gas upon release by CO2 emitters to the photosynthetic organisms.

The present invention is embodied in a carbon dioxide compression and delivery device that uses a plurality of reversible thermoelectric devices and to a method to operate such carbon dioxide compression and delivery device.
