Abstract: A cylinder is provided in which fluid fuels are stored. The cylinder has at least one body in which a fluid fuel is stored; at least one valve located on the body for conveying fluid fuel into or from the body; at least one handle located on the body; at least one collar connecting the said handle to the body; at least one cover on the valve; at least one identifier located at the inner side of the collar and having thereon at least a first visual code specific to the cylinder it is connected; and at least a second visual code on the cover.

Abstract: A cylinder tracking system and method for tracking movements of the cylinders (T) between a filling facility, a sales dealer and a user. The system includes an identifier (5) provided inside the collar (4) of the cylinder (T) and having thereon a visual code (6); a reader system (10) situated in the re-filling facility, and including a reader unit (11) which reads the visual code (6) before and/or after the filling of the cylinder (T) and which resolves the visual code (6) to form identification information of the cylinder (T); a portable reader (12) which reads the visual code (6) on the cylinder (T) and which resolves the read visual code (6) to form identification information of the cylinder (T); and a server to which the identification information of the cylinder (T) obtained by the reader system (10) and the portable reader (12) is transmitted.

Abstract: A hole-making system for making holes on the collar of a cylinder is provided. The hole making system includes a hand unit for making holes on the collar of the cylinder and the hand unit being configured to be used with two hands. The hole making system further includes a control unit configured to control operation of the hand unit. The hole making system further includes a pedal configured to enable a user to control the operation of the hand unit with a foot. The hand unit is held and controlled with two hands and a drilling command is provided by the pedal, allowing the user to control the hand unit in a more reliable manner.

Abstract: The present invention relates to a sulphur-free odorizing composition to be added into liquefied petroleum gas (LPG) in order to allow the user to sense any leakage in case of LPG leakages which might occur in the area of utilization.
