Abstract: A tether line is mounted in a retriever and, when a water vessel is launched into the water, the retriever applies a tension force to the tether line. After the water vessel is launched, the tension on the tether line pulls the water vessel from its launched floating position towards the stationary object. The retriever is rotatably mounted on the water vessel or the stationary object such that it will pivot around a vertical axis and point in a direction towards and along the tether line. A spool mounted on the structural unit holds the tether line, and an electrical or mechanical motor, such as a spring B-motor, places a torque on the spool and a tension on the tether line. After the water vessel is launched, the tension force from the motor pulls the water vessel from a launched position to the stationary object.

Abstract: This invention modifies and redesigns a spring-loaded, retractable supply hose mechanisms used to pan out, retract, and store hoses used for gases (e.g., oxygen), treatments, or fluids, specifically this inventor's prior art, the Retractable Oxygen Supply Hose Mechanism, U.S. Pat. No. 6,065,490. This invention incorporates an “Adaptor Cap” or “Removable Cap” to prevent slippage of the Swivel connector, incorporates a “Removable Cap” into the upper disc or flange of the supply-hose reel and/or into the mechanism housing cover that acts as an “anti-rotational” device, and features bearing surfaces to prevent reel slippage. This internal ratchet system better prevents binding and kinking of the patient's supply, thereby facilitating the storage and the quick-controlled release of the desired amount of oxygen supply hose for patient's Medical Oxygen and other gases delivery, therapy, or treatments.
