Mobile fire-fighting assembly suitable for movement with an aircraft, wherein the mobile fire-fighting assembly comprises a fire extinguisher unit and water supply unit detachably arranged to each other by means of a suitable connection assembly enabling movement of the fire extinguisher unit and water supply unit together as one unit and separately.

A medium processing device includes: a drum that is rotatably supported, that rotates around a rotation axis, and that winds a medium around a peripheral side surface thereof; a first tape that winds the medium sandwiched between the peripheral side surface and the first tape, accompanying rotation of the drum; a movable guide that is movable following a drum diameter of the drum, which changes depending on a winding amount of the medium, and that guides the medium; and a first static electricity elimination section that is provided at the movable guide, that abuts the first tape, and that performs static electricity elimination of an electric charge of the charged first tape.

A flexible layer support structure and a retractable device is disclosed. The flexible layer support structure includes a first thin sheet and a second thin sheet arranged in parallel with each other, as well as and a folding spring group sandwiched between the first thin sheet and the second thin sheet and arranged in parallel. The curved elastic pieces in the folding spring group are smoothly overlapped and connected with the thin sheets, so as to enclose a hollow thin-walled elastic structure that can be overlapped and rolled up, can be automatically straightened and has a flat surface. The retractable device includes a winding shaft, a pressure roller, and a flexible layer support structure installed on the winding shaft. The flexible layer support structure of the present disclosure has the advantages in lightweight, high storage ratio, large unfolded area, simple winding, large load bearing capacity, and less damage.

A dispenser for dispensing plastic film for vehicle repair, the dispenser including: a first support adapted to rotatably support a roll of plastic film, and an aperture, wherein the plastic film can be pulled through the aperture from the roll and retracted through the aperture towards the roll.

A length-adjustable cable device for wiring an aircraft cabin includes a cable and a cable drum with a cylindrical wall which is arranged around an axis of rotation and has an outwardly facing rolling-up surface. The first end of the cable is fastened to or arranged on the cable drum in such a manner that the first connection provided at the first end can be connected to a corresponding connection of another cable device. The cable is wound up onto the rolling-up surface in such a manner that it is unwound from the rolling-up surface by rotation of the cable drum about the axis of rotation thereof when the second end is moved away from the cable drum. The cable drum is configured for fastening to a cabin component of an aircraft cabin.

An automatic line reel includes a flexible line wound onto a motor-driven reel assembly. A processor controlling the motor detects contact pressure between the flexible line and a triangular pressure transducer, automatically extending the flexible line when the contact pressure exceeds a preset threshold. Line extension stops when contact pressure falls below a second preset threshold. The flexible line may be retracted and rewound around the reel assembly by activation of a switch on a wireless remoted control, by a switch on the automatic line reel, or by activation of a smart phone application program in data communication with the processor controlling the reel assembly. A reel assembly is optionally configured to maintain uninterrupted fluid communications through the automatic line reel as the reel assembly rotates. The reel assembly may optionally be configured to maintain uninterrupted electrical signal communication through the automatic line reel.

A retractable anchor assembly according to one disclosed non-limiting embodiment of the present disclosure includes a spool base; a spool mounted for rotation around an axis and at least partially within the spool base; a line attached to the spool; a clock spring mounted to the spool base and the spool to rotationally bias the spool around the axis to automatically retract the line; a button that interfaces with the spool to selectively prevent rotation of the spool; and a spring along the axis to bias the button into engagement with the spool.

The disclosed devices and methods relate to a wire mesh dispensing device which improves the storage, transportation, dispensing, and rewinding of coiled materials, particularly in construction and building maintenance settings such as solar energy and pest mitigation. The dispenser resolves problems from coiled materials prone to expansion or unwinding, leading to storage challenges and safety risks. It features enclosing structures that prevent the coil from expanding beyond a set volume, side plates that keep the material layers aligned, and mechanisms for easy lifting and carrying. The device also includes a stable base with non-slip feet for secure placement on varied surfaces, rollers and a side plate to facilitate low-friction rotation for easy material dispensing in any orientation, and a rewinding mechanism for material take-up or coil tightening.

A liquid connector (160) for a hose trolley (100). The liquid connector (160) includes a body (162) defining an inlet (164) and a plurality of outlets (166, 166). The body (162) allows flow of a liquid from the inlet (164) to one or more of the plurality of outlets (166, 166). A fixing element (168) is adapted to allow coupling of the liquid connector (160) with the hose trolley (100). The inlet (164) of the body (162) has a coupling element (163) which allows coupling of a hose (165). The liquid connector (160) is characterized in that the fixing element (168) is one or more coupling elements (169) provided on the body (162). The one or more coupling elements (169) allow removable coupling of the liquid connector (160) with a corresponding structure.
