A retractable tool lanyard comprises a housing, a drum rotatably connected to the housing, a biasing member interconnecting the housing and the drum, a cord operatively connected to the drum and adapted to be wound about and paid out from the drum, and an engaging mechanism. The engaging mechanism comprises a locking plate connected to the drum, at least one lock pawl connected to the locking plate, and a ratchet plate. When the drum rotates at a predetermined speed, the at least one lock pawl pivots from an unlocked position to a locked position to engage the ratchet plate thereby rotating the ratchet plate with the drum. At least one of a braking mechanism and a clicker pawl are used to create friction to assist in reducing a rate of rotation of the drum.

A tarping apparatus including a base frame, a tarp support boom assembly and a drum member. The base frame includes an inner side and an outer side opposite the inner side. The tarp support boom assembly includes a boom member having a proximal end and a distal end. The proximal end is coupled to the base frame and the distal end extends outwardly therefrom beyond the inner side of the base frame. The drum member extends around the boom member and is rotatable about an axis defined by the boom member. The drum member includes a first end corresponding to the proximal end of the boom member and a second end corresponding to the distal end of the boom member. A tarp positioned over the drum member can be rolled up on the drum member through rotation of the drum member relative to the boom member.

Methods, systems, and computer program products are provided for rapid deployment and retrieval of a frac water transfer system.

A carrier for an elongated, weighty tubular member, and more particularly to such a carrier suitable for use in loading thereon at a first location, transporting to a second location and dispensing along a boundary line along the ground, a flexible, tubular member intended for use as an erosion barrier.

A marine pipeline installation vessel and a method are provided for laying an offshore rigid pipeline in the sea, the vessel at least being adapted to carry out the rigid reel lay method. The vessel includes at least one vertical storage reel for the storage of a spooled rigid pipeline. A left and right reel support structure are provided to support the weight of the at least one storage reel. The left and right support structures are embodied to form a pivoting structure allowing an angular adjustment of the horizontal reel axis about a vertical axis to alter the angular position of the at least one storage reel.

A feeder exchanging carriage includes a reel holder which holds a reel on which a carrier tape which stores electronic components is wound, a feeder holder which holds a tape feeder which performs a feeding operation of the carrier tape, and a base unit which is provided with a pair of front wheels and a pair of rear wheels, and a telescopic unit (a front base and a rear base) which expands and contracts an interval between the pair of front wheels and the pair of rear wheels. In a state where the feeder exchanging carriage is mounted to an electronic component mounter, the interval between the front and rear wheels is contracted by the telescopic unit, and in a state where the feeder exchanging carriage is not mounted to an electronic component mounter, the interval between the front and rear wheels is expanded by the telescopic unit.

The air hose retention device includes a first connector pivotally engaged to a top and an outer spool having a receiving area. A second side of a housing is rotatably engaged to a first side. A cable is wound on the outer spool. A spring is disposed in the receiving area. Pulling of the cable causes rotation of the second side in a first direction and the coiling of the spring. Movement of the cable towards the housing uncoils the spring winding the cable about the outer spool and rotating the second side in a second direction. The cable has a releasable connector which is engaged to a connector hose of a trailer. The air hose retention device may be easily disconnected from both a cab and a connector hose for storage or transportation in a cab of a truck during periods of nonuse.

The invention relates to a movement-tolerant wiring arrangement (10), more particularly for a stand device (1) configured for arrangement in an operating room, comprising a mounting apparatus (20) for movement-tolerant mounting of at least one line (70), more particularly a cable, about an axis of rotation (D) between two connection components (3; 4; 104) that are displaceable, more particularly twistable, relative to one another; and a fastening apparatus (30; 130) for arranging the at least one line relative to one of the connection components (3; 4; 104), more particularly at a socket of the stand device; wherein the mounting apparatus (20) is fixable to the fastening apparatus (30; 130) and configured for movement-tolerant, in particular, rotation-tolerant guidance of the at least one line about the axis of rotation and/or in the direction at least approximately parallel to the axis of rotation. Furthermore, the invention relates to a rotary joint, a socket or a stand device, respectively, with such a wiring arrangement, and the use of such a wiring arrangement (10) at a stand device (1), more particularly in the operating room.
