A large diameter lay-flat hose spool apparatus has a mobile platform with a chassis and wheels. Side supports extend up from the chassis. An axle bears on the side supports, spanning a gap therebetween. Plural spools are rotatably mounted on the axle. Each spool has at least one rim and a length of lay-flat hose wound thereon. A driver rotates the individual spools about the axle independently of the other spools. The driver has a first actuator that moves a drive wheel into and out of contact with a rim of one of the spools. The driver has a second actuator that moves the drive wheel from one of the spool rims to another of the spool rims. A motor rotates the drive wheel. A controller system operated the motor, the first actuator and the second actuator.

An electrical cable reel module for a drone includes a bracket adapted to be firmly fixed to the drone. A reel body is movably and rotatably mounted on the bracket. A first driving device is mounted on one side of the bracket to drive the reel body to rotate and a second driving device is mounted on the other side of the bracket to drive the reel body to move linearly in a first direction. A third driving device is mounted on the bracket to drive the reel body to move linearly in a second direction opposite to that of the first direction. At least one positioning device is mounted among the reel body, the first driving device and the second driving device to selectively drive the reel body to rotate and prevent the reel body from movement and rotation.

A tie-down includes a frame, a handle, a reel, a driving detent, a retaining detent and a brake. In a manual mode, the handle is pivoted back and forth on the frame to make the detents alternately engage with two ratcheted wheels of the reel to reel a strap. To switch the tie-down to an automatic mode, the handle is lifted to disengage the detents from the ratcheted wheels to allow a coil spring to rotate the reel to reel the strap. The brake is in contact with the ratcheted wheels to render the reeling at proper speed. The brake is directly movable away from the ratcheted wheels to allow the coil spring to further rotate the reel to completely reel the strap.

A reel assembly (100) for coupling within a housing (160) includes an axle (110) and a reel (120) defining a rotational axis (X-X). The reel (120) is rotatably mounted around the axle (110) to allow winding of a flexible linear component (130) on the reel (120). The reel assembly (100) further includes a frame (140) which houses the reel (120). Moreover, the reel assembly (100) includes one or more fixing units (150) to removably fix the reel assembly (100) inside the housing (160). The reel assembly (100) is characterized in that the reel assembly (100) further includes a blocking mechanism (170) that operatively couples with the reel assembly (100) and cooperates with the reel (120) for selective rotation of the reel (120). The blocking mechanism (170) disallows rotation of the reel (120) in absence of coupling of the reel assembly (100) within the housing (160).

An automated pipe clearer that is permanently mounted to a building. The pipe clearer has a spool of cable that extends a head assembly down a pipe. The sealed head assembly contains a motor and has a tip at a forward end. A computer control actuates a feeder to extend the cable and connected head assembly down a pipe towards a clog. When the clog is cleared the feeder re-spools the cable leaving the head assembly in the pipe ready for the next clearing operation.

A laser machining apparatus includes, a processing chamber, a window disposed in a surface of the processing chamber, a substrate carrier disposed inside the processing chamber and facing the window, a laser irradiator which irradiates a laser onto the substrate carrier through the window, a protector supplier disposed on a side of the processing chamber, a protector retriever disposed on an opposite side of the processing chamber opposite to the side of the processing chamber, and a protector which connects the protector supplier with the protector retriever, where at least a portion of the protector is disposed between the substrate carrier and the window in the processing chamber.

A hose reel includes a hose reel frame, a hose reel spool rotatably mounted on the hose reel frame for rotation about a rotational axis, a drive coupling attached to the hose reel spool and aligned with the rotational axis, a drive mount attached to the hose reel frame, and a drive module mounted on the drive mount that has a drive shaft connected to the drive coupling.

Media supply units are described for the provision of media such as electricity, gas, data or compressed air. The units comprise a base unit (1) adapted to be installed in or on a ceiling structure and a media outlet supply head (2) connected to the base unit by means of a flexible support member fixed at its ends to the supply head and to the hub of a spool in the base unit. One or more electrical cables or pipes are also arranged between the hub of the spool and the supply head (2), and the flexible support member is a non-stretch conduit (30) which can be wound on to or from the spool in order respectively to raise or lower the supply head relative to the base unit. When lowered, the supply head (2) may rest on a school desk or table.

An apparatus for propelling a plurality of coil clad hoses simultaneously includes a plurality of modules. Each module includes a primary driven bull gear. A follower bull gear is rotatably fastened to a follower axle extending parallel to the drive axle and the follower bull gear meshes with the primary bull gear. A plurality of secondary bull gear/sprocket modules are fastened to each of the axles, each of the modules having a secondary bull gear having teeth extending to a first outer diameter and a sprocket gear having teeth extending a distance less than the first outer diameter. The secondary bull gear teeth of modules on the drive axle mesh with corresponding secondary bull gear teeth of modules on the follower axle to define between adjacent modules an opening width for receiving and passing therebetween a coil clad portion of a high pressure hose.
