Abstract: A gas supply system in the form of a winding device that includes a housing with an aperture, a spool, a one way bearing, an interval locking device, a universal shaft, a spring housing, a spring torque spool and a pair of spring grounding tabs, a main base that stabilizes the housing, a rotating shaft where the main base is disposed on the distal end of the rotating shaft, a rotational bearing that is disposed on the proximal end of the rotating shaft and connects the rotating shaft to the base clamp. The base clamp has a pair of corresponding apertures and secures the gas supply system to a tubular shaped object, and includes an adjustable clamp screw that has a handle and a threaded bolt wherein the proximal end of the threaded bolt is attached to and perpendicularly extends from the handle and the adjustable clamp screw.

Abstract: A stepper actuator including a brake drum and a central gear mechanically connected thereto. The brake drum and the central gear are selectively rotatable in opposing first and second rotational directions. First and second actuation members are moveable through first and second actuation cycles to incrementally rotate the central gear. The actuation members engage and subsequently disengage the central gear as they move through their actuation cycles. The actuation members are configured to rotate the central gear during engagement therewith. A braking assembly is operatively connected to the first and second actuation members and is frictionally engaged to the brake drum to prevent rotation of the brake drum when the first and second actuation members are each in a retracted position as occurs when neither is moving through a corresponding actuation cycle.

Abstract: A hose reel includes a support casing, a drum rotatably fitted inside the casing and connected to it by an elastic rewinding element. The drum provides a flange integral with it and couplable in rotation with a locking disc equipped with teeth engageable with opposing teeth capable of stopping its rotation. An elastic separator is provided between the flange and the locking disc to keep the latter in a first position axially distanced from the flange, teeth and counter-teeth mutually engaged to allow the flange to draw the locking disc into integral rotation with it, and cam and counter-cam which, in the event of the flange exceeding a predetermined threshold speed cause the axial displacement of the locking disc into a second position adjoining the flange in which its teeth engage with the opposing teeth to produce the consequent stopping of the rotation of said drum.

Abstract: The present invention provides a water hose winding device. The winding device main body includes a water hose winding rack, a water inlet adapter, a water hose exit guide hole, a driving motor, and a gearing component. The water outlet end of the water hose is configured with a wireless winding control mechanism, which includes a radio signal transmitter and a control switch. The winding device main body is configured with a radio signal receiver to receive the wireless control signal transmitted by the radio signal transmitter, and the driving end radio signal receiver is electrically connected to the driving motor. When the driving end radio signal receiver receives the wireless control signal, it can start or shut off the driving motor.

Abstract: A vacuum system has a cabinet that can be mounted to a wall. The cabinet includes a hose storage compartment with a hose drive assembly for automatically extending and retracting a vacuum hose. A portable vacuum unit can be removably docked to the cabinet and connected to the vacuum hose so that waste can be picked up the vacuum hose when the portable vacuum unit is docked. When undocked, the portable vacuum unit can be used alone.

Abstract: The hose reel apparatus includes a tube motor having a housing that at one end is bolted to a mounting bracket leg to extend within the reel drum and a motor shaft extending within and connected to one end portion of a sheath tube which is also extends within the drum. The opposite end portion of the tube is connected to the reel side plate which is adjacent to the above mentioned leg to rotates the reel. Swivel mechanism is mounted to the other mounting bracket leg, and extends into the drum and is adapted to be non-rotatably connected to a conduit and to a hose that is to be wound onto and unwound from the reel drum.

Abstract: An improved reeling device including a reel driven by an electric motor.
