The present invention provides a telescopic jacking stepwise rollback-type reel sprinkling irrigation machine, including a chassis, a locking-type reel, a sprinkling irrigation apparatus, and a stepwise driving apparatus. A locking channel in a circumferential direction is disposed on the locking-type reel. The stepwise driving apparatus includes a lifting cylinder, an upper caliper, and a lower caliper, and the upper caliper and the lower caliper are clamped to be mounted on the locking channel. Pressurized water is used in the telescopic jacking stepwise rollback-type reel sprinkling irrigation machine to drive the lifting cylinder to realize periodic lifting motion of the piston rod, so as to drive the upper caliper to move up and down to be engaged with the locking channel of the locking-type reel intermittently, thereby driving the locking-type reel to roll back intermittently to automatically reel in a sprinkling irrigation PE hose.

A mobile, coiled tubing drilling apparatus with a rotary drill head, includes a non-rotating mast on a mobile platform. The mast has mounted thereon an injector below a coiled tubing reel. The injector defines an operational axis for the coiled tubing. The rotary drill head is pivotally mounted on the injector so as to be movable between a retracted position away from the operational axis and an operating position in line with the operational axis. The rotary drill head includes a top swivel for non-rotating connection to the coiled tubing and a bottom spindle for rotating connection to a pipe section. The top swivel and the bottom spindle provide fluid communication between connected coiled tubing and connected pipe section during operation.

A fall protection device is used to connect with a safety belt, including a frame having a receiving space, a shaft disposed on the frame, a decelerating member connected to the shaft and disposed in the receiving space, and a safety belt base fitted around the decelerating member. An outer peripheral surface of the decelerating member has a plurality of friction surfaces arranged at intervals. The safety belt base has an outer peripheral surface adapted to be wrapped by the safety belt and an inner peripheral surface being in contact with the friction surfaces thereof. With the design describing above, the friction surfaces rub the inner peripheral surface to generate a rolling friction, thereby to slow down an unwound speed of the safety belt.

In accordance with the present invention, a system and method for a powered vertical axis hose reel is shown. In accordance with one aspect of the present invention, a powered hose reel is disclosed having a spool around which a hose may be coiled, in which the spool is on a vertical axis relative to the ground. In various embodiments, the powered hose reel includes a programmable controller for implementing a rewind protocol adapted to encourage the hose to fill from the bottom of the spool cup to the top.

Discussed are a flexible display apparatus and a rollable display apparatus comprising the same, in which rigidity reliability is secured against a physical impact. The flexible display panel includes a display unit provided on a flexible substrate and a back cover disposed on a rear surface of the flexible display panel. The back cover includes a panel supporting part including a plurality of openings, having a size greater than a width of the flexible display panel, and supporting the flexible display panel, and a sidewall part protruding from each of one edge and another edge of the panel supporting part.

A tensioning system for articles of footwear and articles of apparel is disclosed. The tensioning system includes a spool system that can be engaged or disengaged from a driveshaft through the use of a cam device. The motorized tensioning device includes a torque transmitting system that allows for incremental tightening, incremental loosening and full loosening of the tensile element.

Systems, devices, and methods for drain cleaning using high voltage, high frequency AC electrical power supplied through a video push-cable are disclosed. In one embodiment, a drain cleaning system may include a cable for carrying electrical control and/or data signals as well as alternating current (AC) power at a high voltage and high frequency relative to AC mains frequencies.

A holder for straps includes a base including a body portion and a tail portion, and a waist where the body portion and the tail portion join. The base defines first and second horizontally opposed recesses and a wrap area disposed therebetween. First embodiments of the holder include pegs disposed on opposing sides of the wrap area. The pegs can engage with S-hooks, D rings, snap hooks, carabiners and the like. Second embodiments of the holder include a base defining slots from edges of the body portion and disposed on opposing sides of the wrap area. The slots can engage with J-hooks, T-hooks, U-hooks, and the like. After securing the hook thereof, each strap is wrapped around the base through first and second recesses. Straps can be secured by disposing a loop such as a loop of bungee cord or a tie about the waist and tightening the cord or tie.

A device used to release, retract and store a cable or a cable-like structure provides an easy way for cable or cable-like structure applications. The device can be widely used for all kind electronic devices in private homes and in public facilities tidily and safely. By apply the devices in present patent application, there will significantly reduce safety hazards and solve problems related to cable messing up or winding each other around electrical devices.

A mounting bracket for a cord reel assembly is provided. The bracket includes a base plate and a pair of side rails. The base plate has one or more mounting openings. The pair of side rails define a keyway between each of the side rails and the base plate. An assembly of a cord reel and the mounting bracket are also provided, as is a method of a method of installing a cord reel using the mounting bracket. In some embodiments, at least one rail of the pair of side rails includes a tongue extending therefrom. The tongue is configured for securement of a supply device thereto.
