A system is described wherein a cryogenic liquid transport fluid is used as in thermal communication with a volatile gas as a second cryogenic liquid. The volatile gas in the liquid state enables transport of additional volatile substances that cannot be transported in the liquid state employing only the cryogenic liquid. The thermal communication between cryogenic liquids is a thermal cascade.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head

The present description relates to an adsorbent monolith, method to make the adsorbent monolith, and a gaseous storage system that includes an adsorbent monolith according to the present disclosure. In particular, the adsorbent monolith includes adsorbent, a binder, and a scaffold material.

Gas pressure actuated fill termination valves for cryogenic liquid storage tanks and storage tanks containing the same.

A novel and improved inventive valve with a regulating function is provided that is capable of filling to higher fill pressures than previously attainable with conventional C-10 on-off valves. The valve contains a single flow passageway by which gas dispenses and enters the valve. A fill adapter is specially configured to engage the valve to allow filling at the higher pressures along the single flow passageway. The structure of the valve allows greater utilization of cylinder capacity; simplifies filling and dispensing with the single flow passageway; and allows for regulating gas pressure during delivery without increasing the overall size of the cylinder package.

A pressure regulator device for use within a pressure-regulated fluid storage and dispensing vessel primarily in low flow, low delivery pressure applications. Regulator stiction challenges have been solved with an improved poppet assembly using different poppet element configurations as well as an improved bellows structure in the pressure-sensing assembly that provides more flexibility during contraction and expansion of the diaphragm elements.

A gas cylinder monitoring system (10) for monitoring the contents of a gas cylinder in an EMS vehicle (50) including a gas cylinder (12) for receiving and distributing gas therein, an individual cylinder monitoring system (14) operable to monitor data associated with the gas cylinder (12) and having a cylinder monitoring transmitter (16) operable to broadcast the data, and at least one receiving station (60,70) having a receiver (18,20) operable to receive the data from the individual cylinder monitoring system (14) and indicate if the contents of the gas cylinder (12) are below a pre-determined threshold and require replacing.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head.

A method includes depositing graphene into a hardener, mixing the hardener and the graphene to produce a homogenous composite mixture, adding a resin material to the composite mixture to produce an epoxy graphene material, coating a structure with the epoxy graphene material, aligning the graphene sheets in the in-plane orientation, and curing the epoxy graphene material.

A valve integrated pressure regulator (VIPR) device is provided that includes a gas flow valve arrangement, a shroud and digital gauge display that can be attached or coupled to a gas cylinder, and which can monitor the amount or pressure of the gas in the gas cylinder. Features of the disclosed valve integrated pressure regulator device include an electronic control, electronic alarm and the electronic display that are powered by a battery that may be disposed within the shroud. The battery and/or electronic control are accessible via a removable access panel disposed on the front surface of the shroud.
