An automated aisle runner includes an automated control unit and an aisle runner. The automated control unit includes a housing and a runner roller, wherein the runner roller is rotatably mounted within the housing. A fixed end of the aisle runner is connected to the runner roller, while a runner body is disposed around the runner roller, such that the runner body is wound around and unwound from the runner roller as the runner roller is rotated by a motor. A guide assembly is provided to ensure the aisle runner is extended or retracted in a straight, smooth manner, eliminating problematic tangling. A plurality of lights is positioned along the runner body, providing enhanced visual effects for the aisle runner, while a speaker provides audial effects. A microcontroller allows a user to control the color and pattern of the plurality of lights and the audio files played through the speaker.

A cylindrical cartridge used for the storage and protection of all types of barrier fencing. The device is designed to extend the life of barrier fencing, reduce waste and reduce cost. The cartridge has an interior hollow pipe shaft with rollers mounted to the shaft to create a spool. The spool shaft extends through the top of the cartridge and is fitted with a manually operated crank handle. A vertical slotted opening in the side of the cartridge of varying widths dependent on the barrier material being used allows the extraction and retraction of the barrier fencing. The bottom of the cartridge has an opening in the center equal to that of the interior dimension of the hollow shaft. The bottom opening allows for the mounting of the cartridge to a ground spike or stabilizing plate.

An apparatus is described herein that may generally include an air pump, a rotatable drum, a flexible hose, and first and second housings. The drum may draw in and let out the flexible hose. The pump may be connected to the flexible hose. The first housing may enclose in inner portion of the drum, and may include a first air intake. The pump may be disposed within the first housing. The second housing may surround the drum and may include a second air intake. The flexible hose may pass through the second air intake. The first intake may be aligned perpendicular to the second air intake. Alternatively, the first intake may be aligned parallel to the second air intake on a side of the drum opposite the second air intake. Sound emitted from the pump may pass over, and be absorbed by, the flexible hose within the second housing.

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 retractable leash device (e.g., for pets, children, or the like) having a length control system for limiting the extendable length of a main line is provided. The device includes a cover plate mounted on a wind-up spool and having at least one ridged channel that interacts with a length control switch during line extension to control the extendable length of the main line while simultaneously maintaining the retractability of the main line.

A compact inflator is described herein. The inflator may include a rotatable drum, an air pump disposed within the drum, a fixed securing mechanism that provides structural support to, and enables rotation of, the drum, a power supply, and an electric power transmission mechanism. The drum may draw in and let out a hose. The hose may have a first end and a second end, the first end having a connection mechanism that connects the hose to an inflatable object. The air pump may be connected to the second end of the hose. The power supply may provide power to the motor, and may be coupled to the pump or the power supply. The power transmission mechanism may include a slip ring assembly or a pair of parallel inductors, one which rotates with the drum about the other.

A portable hose storage assembly includes a reel. A hose is wrapped around the reel thereby facilitating the hose to be stored. A bracket is coupled to the reel. The bracket guides the hose when the hose is wrapped around the cylinder. A base is provided and the base may be positioned on a support surface. The reel is selectively positioned on the base.

A wire tightening apparatus includes a housing having a ratchet gear formed in its inner periphery in a circumferential direction. A winding member is rotatably inserted into the housing, with a wire being wound therearound. A support part radially protrudes from the upper portion of a coupling shaft coupled to the housing. An intermediate member includes an engagement restriction part that is engaged with the ratchet gear and is restricted from rotating. The intermediate member has a resilient coupling hole in its center, with a resilience restriction part on the periphery thereof. The engagement restriction part is provided on an end of a blade extending from a body and having a resilient support force. The resilience restriction part is elevated by an external force coupled to the upper portion of the winding member and is supported by the outer periphery of the support part in lifted and lowered states.

The invention relates to an underwater antenna device with a nonstationary antenna, an extension mechanism and a repositioning mechanism, wherein an extending force can be applied in a direction of the extending force by the extension mechanism of the antenna and an opposing force can be applied in a direction of the opposing force, in the opposite direction to the extending force by the repositioning mechanism of the antenna, characterized in that the repositioning mechanism or a part of the repositioning mechanism is designed as selectively nonstationary, so that, by selected changes to the position, the antenna can be positioned in a retracted position, an extended position or an intermediate position.

A buoyant conduit storage system comprising a reel for storing conduit and a drive arrangement for rotating the reel. The reel is rotatable about a substantially vertical axis of rotation to reel and/or unreel the conduit. The drive arrangement drives the reel at the axis of rotation. The buoyant storage system may provide for the storage and/or transportation and/or deployment of reelable conduit.
