Each carriage assembly (100) supports a pulling assembly (200) for applying the pulling forces. A trapezoidal carriage body (102) of the carriage assembly (100) rolls in the carriage track (24), and the carriage assembly also includes a tower positioning mechanism (104) to hold the pulling assemblies (200) in place while the carriage body (102) is are rolled on the track (24). The carriage assembly (100) also includes a locking mechanism (106) to lock them in place during a vehicle a pull.

Abstract: An aerator is provided having a front axle, including a differential and a tine wheel assembly which may be raised from the ground during maneuvers of the aerator while power continues to be supplied to the front axle, and a tine wheel assembly is provided which allows the operator to repair and change the configuration of the tines of the tine wheel assembly.

Abstract: A coupler for attaching an implement to a tractor is provided. The coupler has three pivot arrangements allowing pivoting about three axes that are generally normal to one another with two axes of pivoting lying in substantially in a first plane and the third axis of pivoting intersecting that plane at a variable angle in a second plane generally perpendicular to the first plane. The three axes of pivoting substantially intersect and the implement may be attached wherein the load from the implement is directed downwardly and over the draft arms of the tractor.

Abstract: There is disclosed a movable and transportable unit for carrying tools or implements for different types of equipment used at different locations. The unit is mountable and removable from a trailer bed, so that the trailer can be used for other purposes. The transportation unit has upper and lower mounting surfaces separate by a frame, and where at least one side of the unit is relatively open to permit loading and unloading of implements or tools onto the surfaces or in retainers associated with the unit.

Abstract: An apparatus is provided to facilitate sod destruction and decomposition by cutting and crushing primarily horizontal roots and rhizomes while leaving vertical roots uncut. Multiple gangs of colters are attached to a frame, the colter gangs are arranged in staggered relation with respect to each other. The staggered relationship of the colter gangs allows the apparatus to cut relatively narrow strips of sod. A method of operating the apparatus is provided in which the apparatus is operated across a sod field in a first direction to cut the field into long, narrow strips of sod. The apparatus is then operated across the same field in a direction relatively perpendicular to the first direction, cutting the strips of sod into small pieces.

Abstract: An improved apparatus for coupling a tug boat to a barge having a notch in its stern is provided. Coupling units mounted on the opposite sides of the tug have extendable and retractable rams which engage with channels on the opposite sides of the stern notch. Each ram includes two portions. The first portion can be non-rotatable and is extended and retracted by an actuator screw driven by a motor. The second portion can rotate relative to the first portion. Additionally, the second portion is capable of axial movement relative to the first portion. A load cell can be positioned between the first portion and the second portion to provide axial extension of the second portion to provide sufficient engagement force to couple the tug and barge.

Abstract: An excavation cleaning tool or dredge is provided which rotates and scrapes together and captures the loose soil, sand and gravel debris at the bottom of the hole to provide a clean, flat-bottomed hole which is free of compressible excavation waste material.

Abstract: A drain assembly is provided that eliminates the need for reconfiguring of existing plumbing during installation of a deep-sink assembly while maintaining a suitable working height. The drain assembly including a hollow body, a valve within the body and a mount to operably connect the valve within the hollow body. The hollow body includes an inlet, an outlet, and an inner wall positioned between the inlet and the outlet. A fluid path enters the inlet of the body in a first direction and is diverted to a second direction substantially perpendicular to the first direction by the inner wall. The diverted fluid path exits the body moving in the second direction. The mount is located at least partially within the outlet.

Abstract: A collision deformation sensor for use within the crush zone of a vehicle consists of first and second spaced apart substrates for mounting to or forming respective vehicle components, with a compressible carrier medium filling the space between the substrates. The carrier medium is formed from a material transparent or translucent to light or other wave energy, and includes wave energy scattering centers dispersed within the medium to create a scattered energy volume. Alternatively the carrier medium forms a hollow cavity, the inside surface of which is coated with a wave energy dispersion coating. A source and receiver of light or other wave energy communicates with the carrier medium. Signal couplings and processors are associated with the source and receiver.

Abstract: A catheter button system for anchoring a catheter to a patient's body tissue, consists of a catheter button having a primary aperture for snugly receiving a catheter tube, and at least one secondary aperture. A cord loop extends through the secondary aperture. The loop is for catching a surgeon's suture needle for fastening the button system to the patient's body tissue. Perferably, the button consists of separate upper and lower components, and the cord loop holds the button components together, as well as serving to anchor the button to a patient's body with a stitch of suture thread. Perferably, the primary aperture is central to the button, and two secondary apertures are spaced equidistant from the primary aperture, on opposing sides of the button. The invention also relates to a method for anchoring a suture to a patient's body, by joining a button to the suture, the button having at least one pre-formed loop.

Abstract: The present invention relates to a spoke nipple for bicycle wheels and similar contrivances comprising a body having a longitudinal axis in which a drill hole is disposed essentially concentrically to said longitudinal axis. A screw thread is provided extending at least over one longitudinal section of said drill hole which is provided for receiving a spoke having a corresponding thread. A quantity of glue is disposed on the spoke nipple and so structured that the glue is activated to function as an agent to secure the thread upon screwing said spoke nipple onto a spoke.

Abstract: An apparatus is provided that prevents a pet from tipping over a food dish. The dish is placed in an open framework having a lid that covers only a portion of the dish, allowing a pet to access the dish for feeding. The apparatus includes spikes to anchor the framework into the ground. Additionally, the apparatus includes extensions, to adjust the height of the dish above the ground.

Abstract: Freewheel hub, especially for bicycles and similar contrivances comprising a hub axle, a hub shell arranged concentrically thereto, a rotator arranged concentrically to said hub axle for receiving a sprocket wheel with pinions and a freewheel means disposed with ratchet pawls. Roller bearings are employed for the rotatable support of said hub shell relative the hub axle and for the rotatable support of said rotator relative said hub shell and comprise roller bodies each respectively disposed at a predetermined distance from one another.

Abstract: A method and apparatus is provided for removing contaminates, in particular, volatile organic contaminates from groundwater by providing a well that combines air stripping and air sparging apparatus within a single well to provide in-ground treatment of contaminated groundwater.
