Abstract: An interchangeable sports implement grip is a device that allows the user to quickly change the handle of a sports implement or any other device that utilizes a handle. The device features an elongated mount onto which a handle may be attached. The elongated mount features a tapered design while the handle features a corresponding tapered mount-receiving cavity. The tapered design of the elongated mount and the mount-receiving cavity prevents any shifting, sliding, vibration, and play between the handle and the elongated mount. The elongated mount is compressed further into the mount-receiving cavity via a tensioning mechanism. The device may additionally feature a locator key and keyway slot or a similar mechanism to prevent rotation of a handle and elongated mount of circular or cone-shaped design.

Abstract: An apparatus for removing deposits from the interior surface of a conduit while being advanced through the conduit by virtue of pressurized upstream liquid includes front and rear assemblies interconnected in a manner to permit limited movement there between. The rear assembly contains a mechanism for receiving the upstream liquid and increasing its pressure. The liquid of increased pressure is fed to a rotating nozzle in the front assembly. High velocity water jets emergent from the nozzle strike the interior surface of the conduit to dislodge deposits. A resilient sidewall in one or both assemblies expands by virtue of the liquid of increased pressure to apply a controlled braking force against the interior surface of the conduit.
