A tank manufacturing method includes the steps of (a) forming a reinforcing layer before hardening, (b) embedding at least a part of a label into the reinforcing layer before hardening, and (c) winding glass fiber with thermosetting resin before hardening impregnated so as to cover the label to form a surface layer before hardening. The step (a) includes (a1) forming an inner layer before hardening, and (a2) forming an outer layer before hardening having a cover rate lower than the inner layer before hardening and lower than 100%, the outer layer before hardening being arranged on the inner layer before hardening.

Provided are a method for producing a tank with an outer surface profile that allows a thin label to be easily and firmly attached to a surface thereof, and also such a tank. The method for producing the tank, which includes winding fiber bundles containing an uncured resin component in multiple layers around the outer surface of a liner in a first pitch width so as to form a fiber reinforced resin layer, further includes: winding fiber bundles in a second pitch width wider than the first pitch width so as to form a gap with a required width where no fiber bundle is present between adjacent fiber bundles in winding the fiber bundles to form an outermost layer; shaving off a tip end portion of a projection made of a resin that has cured after bleeding into the gap, with a portion of the projection in a predetermined height left unshaved; and attaching a label to a surface obtained through shaving off the tip end portion.

The invention is directed to a device for inflating a tire that includes a housing with at least one first connection port and at least one second connection port. The second connection port includes connecting means to interconnect the device with a pressure tank. The first connection port is fluidically connected to the second connection port by means of a fluid passage. Furthermore the device comprises a first valve. When a pressure tank is connected to the second connection port and when the first valve is in a closed state, the first valve is suited to prevent air from flowing from inside of the pressure tank out of the first connection port. When the first valve is in an open state, it is suited to allow passage of air from inside of the pressure tank through the fluid passage to the first connection port.

A device for the storage of compressed hydrogen gas comprises a plurality of glass capillary tubes each having a sealed extremity and an open extremity, wherein said plurality of glass capillary tubes is sheathed in an external tubular cover, and wherein the open end of a bundle of said tubular covers is housed in an adaptor, and wherein said adaptor is suitable to allow compressed hydrogen gas to be added to, and to prevent said hydrogen gas from escaping from, said glass capillary tubes.

Container (100) with valve for storing, dispensing and transporting aircraft fuel additives, which allows speeding up and simplifying the mixing and refueling process, through numerous smart functions and an innovative valve system (40). The invention uses recyclable materials, reduces the mixing action time and/or the need to mix large quantities of liquids, guarantees the safety of things and people in the work area and is easily transportable due to its ergonomic and compact shape. The device comprises a body (10) capable of resisting impacts; a hermetic sealing system (12) to protect the contents; a coupling system (16); a sensor or a level gauge (17) connected, possibly where the working environment allows it, to an alarm system (14), suitable to warn the operator of the exhaustion of the additive by means of a luminous LED signal.

A device for restoration by encapsulation of a breached, leaking, or degraded pressure retention item. The apparatus may include multiple features for reducing loads on the pressure retention item, including a filler or liner plate, filler material, and an angled attachment point between the apparatus and the pressure retention item. The apparatus may include inspection ports for viewing, pressure, or leak detection. The apparatus may include a guide track for improved welding to fasten the apparatus to the pressure retaining item. The apparatus may include an expansion joint or bellows, allowing lateral and/or axial movement of the device and/or the pressure retaining item.
