The design and structure of a regulated digital dispense apparatus is exhibited in this disclosure. The MEMS mass flow meter embedded with a Bluetooth communication device and powered by a battery pack is designed to replace the mechanical low pressure gauge in a conventional gas dispense regulator such that the dispensed gas flowrate as well as totalized dispensed gas volume in each session or in consequent sessions can be continuously and precisely registered. The measured data are further relayed to local users via the local display or physical data port as well as via a paired smart device running a customized APP that can further relay the data to a designated cloud for cloud data processing, and the data can be streamed reversely. This disclosure shall assist and realize the ultimate optimized management for the users, distributors and/or gas manufacturers in the gas dispensing industry.

Various cryogenic fluid reporting systems are disclosed. In some embodiments, the system comprises a cart with a base and a load cell. The base can receive and support a cryogenic fluid tank and the weight of the cryogenic fluid tank can be applied to the load cell. The cart can include a transmitter configured to transmit a signal indicative of the weight applied to the load cell. The system can include a receiver configured to receive the signal from the transmitter. The system can include a computing system in communication with the receiver. The computing system can include software configured to correlate the signal indicative of the weight of the cryogenic fluid tank to a fill amount of the tank.

The present invention relates to a natural gas hydrate tank container loading system for transporting natural gas hydrate, and the present invention provides a natural gas hydrate tank container loading system which enables automated connection of an electric power line and a boil-off pipe, and may automatically connect an electric power line and automatically connect the pipe by simultaneously stacking respective natural gas hydrate tank containers, in order to solve problems of a transportation method using the existing natural gas hydrate tank containers in the related art in that an operation of connecting an electric power line to a refrigerator for minimizing the occurrence of boil-off gas and maintaining a phase equilibrium condition in the tank containers and an operation of connecting the pipe for discharging the boil-off gas need to be manually and individually performed for long-distance transportation of a large amount of natural gas hydrate by using a ship, which causes an inconvenience.

The invention relates to a valve block (1) for a pressurised gas cylinder (20) comprising: an inner gas passage (2) providing fluid connection between a gas inlet opening (10) and a gas outlet opening (11); a gas monitoring system (3) arranged on the inner gas passage (2), making it possible to monitor and/or adjust the flow of gas circulating in said inner gas passage (2); a system for selecting and/or adjusting the flow of gas, comprising a movable operating member (4) which can be actuated by the user and engages with the gas monitoring system (3) in order to monitor and/or adjust the flow of gas exiting via the gas outlet opening (11); an electronic control system (7, 7, 8) making it possible to control an actuator device (5); an actuator device (5) capable of controlling the movement of a mobile mechanical member (6) in response to a control signal output by the electronic control system (7, 7, 8); and a mobile mechanical member (6) acting on the operating member (4) of the system for selecting and/or adjusting the flow of gas, in response to an actuation by the actuator device (5), such as to block or release the mobile operating member (4). The invention also relates to a gas distribution assembly comprising a gas cylinder (20) provided with a valve block (1) according to the invention, protected by a protective cover arranged around at least one portion of said valve block (1).

This invention discloses an inflator mechanism for rafts and life vests that performs a multitude of functions required for rescue and underwater deployment of personnel and devices. The inner cylinder in this disclosure is actuated by a plethora of inputs, manual, automatic selectable pressure sensing, or dualled hydrostatic sensors which can each be safely selected by function selection. Since the inflator uses spring discs to drive a penetrator which mechanically punctures a membrane of an inflation gas source and actuated by an electronically controlled solenoid, dissolvable elements, conductivity switches and preset check valve actuators are eliminated increasing the safety and reliability of the actuator. Electronic control further permits user enabling of inflation depth actuation and the multiple water sensors prevent failure of actuation due to splashes and humidity effects on sensors. The actuator mechanism is self cocking, indicates proper installation of gas source enables use of several gas source cylinders and is multiply reusable.

Systems and methods for controlling the temperature and pressure of a cryogenic liquid methane storage unit are provided. The disclosed systems and methods generate methane gas from a reservoir of liquid methane stored within the methane storage unit, vent the methane gas through one or more outlet valves connected to the methane storage unit, and generate electric power using the vented methane gas. The generated electric power can then be used to initiating a cooling cycle, which reduces the temperature of said reservoir of liquid methane and reduces the pressure in said methane storage unit. Micro anaerobic digesters and methane storage units may be configured in a networked environment with a central controller that monitors remote units.
