An apparatus for fastening a pair of gas vessels includes: a plurality of first units formed of a composite material, spaced apart from each other in parallel with each other in a length direction of the gas vessel, and having the pair of gas vessels seated on both sides thereof; a second unit formed of a composite material and extending in the length direction of the gas vessels to integrally connect the plurality of first units; and a plurality of fastening units each of which extending along a circumference of the gas vessels to enclose the gas vessels seated on the first units and having both ends connected to the first units.

A modular support system for a self-contained breathing apparatus, comprising: a support for a self-contained breathing apparatus, the support comprising a cylinder mount and a component mount, wherein the cylinder mount is for mounting a single cylinder of compressed gas to the support in a single cylinder configuration of the modular support system; and wherein the component mount is for mounting a functional component for the self-contained breathing apparatus in the single cylinder configuration; the system further comprising an adaptor bracket for mounting an assembly of multiple cylinders to the support in a multiple cylinder pack configuration; wherein the adaptor bracket has mount portions configured to be mounted to the component mount and the cylinder mount. There is also disclosed an adaptor bracket and a method of converting a single-cylinder support.

A holder for compressed gas cartridges may consist of a geometric body with a plurality of elongated cylindrical holes, each hole may be adapted to removably engage the neck portion of a standard compressed gas cartridge. When the neck portion of a standard compressed gas cartridge is inserted into the elongated cylindrical hole in the geometric body, the compressed gas cartridge may be securely but removably attached to the geometric body. The angle and orientation of the compressed gas cartridges may form a support structure for the geometric body.

A self-contained breathing apparatus includes at least one air tank having a regulator, and a back plate configured to removably receive the air tank. The back plate has a plate having a tank engagement surface for engaging at least a portion of an air tank, a receiving cradle on the plate configured to receive the regulator of an air tank, and a locking mechanism associated with the cradle and/or the plate for releasably locking the regulator and/or the cradle relative to the plate. The locking mechanism has at least one locking member configured to move between a first locked position, wherein the locking member engages the regulator and/or cradle to restrict removal of the regulator and/or the receiving cradle from the plate, and a second unlocked position, wherein the locking member disengages from the regulator and/or the cradle to permit removal of the regulator and/or the cradle from the plate.

A grilling device and method for operating a grilling device. The grilling device comprises a grill housing, a gas-operated heating element, and a connecting element which can be connected to a fuel container. The gas-operated heating element is connected to the connecting element by means of a connecting conduit, wherein the connecting conduit has a fuel withdrawal portion adapted to carry fuel in a liquid form and an expansion portion adapted to carry the fuel in a gaseous state. The fuel withdrawal portion is connected to the connecting element upstream in the flow direction of the fuel and opens into the expansion portion downstream in the flow direction.

A pressure vessel assembly including a pressure vessel including a cylinder part and a first side part and a second side part, the first side part and the second side part each having a dome shape and being provided at two opposite ends of the cylinder part, nozzle members respectively provided on the first side part and the second side part, and a plurality of protectors connected to the nozzle members and configured to surround a respective outer surface of the first side part or the second side part.

A tank holding device includes a band configured to tighten a hydrogen tank. The band includes a band-shaped base portion extending along an outer circumference of the hydrogen tank, a plurality of pressing portions projecting from both sides of the base portion in a width direction orthogonal to a longitudinal direction of the base portion and configured to apply a pressing force to an outer peripheral surface of the hydrogen tank by elastically deforming in abutment against the outer peripheral surface of the hydrogen tank, and a deformation limiting portion configured to limit deformation of the pressing portions to a specified amount.

A tank holding device includes a band configured to tighten a hydrogen tank. The band includes a band-shaped base portion extending along an outer circumference of the hydrogen tank, and a plurality of pressing portions projecting from both sides of the base portion in a width direction orthogonal to a longitudinal direction of the base portion and configured to apply a pressing force to an outer peripheral surface of the hydrogen tank by elastically deforming in abutment against the outer peripheral surface of the hydrogen tank. At least an elastic member is provided in a gap between the band and the hydrogen tank to fill the gap.

An air tank assembly disposed within a cab of a vehicle having a floor and a seat for a vehicle occupant comprises a platform mounted to the floor of the cab of the vehicle. A base of the seat is mounted to the platform opposite to the floor of the cab of the vehicle. At least one tank providing storage for compressed air is located by the platform above the floor of the cab of the vehicle adjacent the base of the seat.
