Abstract: A grinding shoe is designed to be a passive grinder which is advanced within the bore of a pipe being rotated in a typical pipe operation. Apparatus currently used to deliver reamer rocks on the end of a rotating lance can be modified to achieve considerable cost savings. Specifically, the apparatus utilizes a lance for advancing the shoe within the pipe without rotation. The shoe is affixed near the end of the lance in a selected attitude which determines the degree of grinding to be accomplished. A pair of shoe walls extending substantially paraxially with the rotating tube form a dual reaming head which engages the pipe interior across a chord over the bottom of the pipe.

Abstract: An improved self-propelled mobile track vehicle (MTV) capable of traveling by road at normal highway speeds and traveling by rail after conversion at a narrow railroad crossing by producing a device for rotating the vehicle 90 degrees. The vehicle is powered by a diesel engine driving through a power shift transmission to the roadway and railway axles. A significant advantage over other types of road/rail vehicles is that 100 percent of the vehicle's weight is carried on the rail wheels, which are powered and braked, thereby allowing higher and safer rail speeds. One way to convert the vehicle from roadway travel to railway travel is to maneuver it into a position parallel to the track at a road crossing. The rail axles are then extended and road axles retracted. In addition, a turntable mounted at the vehicle's center of gravity also allows the vehicle to convert at a narrow road crossing. While at railway/roadway crossing the unit raises and rotates 90 to align with the desired roadway or railway.

Abstract: An improved hood enclosure for isolating wood pulp washing equipment from the ambient environment. The hood has a pair of end members, a pair of skirts along each side to connect to the end member together, and an upper spine also connected at each end to the end members. A pair of clamshell style doors are mounted to the spine along longitudinal hinge lines and are opened vertically. A plurality of access doors are positioned within the skirts, and a plurality of spray or shower pipes penetrate the hood through an end panel to deliver wash liquid to the internal wash drums positioned within the wash vat. Several sealing methods are incorporated to provide sealable access for the access doors, the clamshell doors, and access to the interior of the washing vat for the shower pipes. The clamshell doors abut a peripheral neoprene sealing gasket and are held against the gasket by their own weight.

Abstract: An electric wire fence stringing and retrieval apparatus uses a carriage which can be pulled behind a vehicle and which supports a spool on which electrical fence wire is stored. The spool has an associated brake which allows wire to be played out as the carriage is moved during a fence stringing operation without the spool over spooling. Likewise, the brake can be disengaged during retrieval. The spool is inertially loaded such that rotation of the spool easily overcomes the weight of the wire during retrieval. A manual level winding unit is provided to allow the user to properly position the wire on the spool. The carriage includes storage for primary and supplemental fence posts and fencing tools which may be needed.

Abstract: A novel interconnection of the jaw, wedge and operating handle in a fifth wheel facilitates the provision of a secondary locking mechanism which further insures the security of the system. In the invention, the jaw is connected to the operating handle by a pivoting timing lever which pivots off a pin on the jaw such that the jaw remains engaged with the fifth wheel until the wedge is substantially removed from engagement with the jaw. In cooperation with the primary locking mechanism, a secondary lock is provided at the end of the operating handle such that a pin arrangement engages a stop on the fifth wheel assembly until positively released by the operator.

Abstract: A motorcycle stand uses a novel combination of components including a primary capture mechanism that consists of a transverse rod on which are mounted two vertical capture plates that translate inward as the motorcycle tire enters the stand. The capture plates are mounted for rotation orthogonally to the translation concomitantly with a tire contact plate. Translation of the plates is accomplished by the spring action and location of a pair of compressible pivot rods that have one end mounted forward and outward of the main rotation axis of the tire contact plate and the other end affixed to the sides of the capture plates. Forward rotation of the primary capture mechanism results in inward translation of the capture plates until they contact the tire side-wall. Further rotation results in compression of the springs in each pivot rod. A second, upper engagement shoe cooperates to ensure that the tire is fully captured.

Abstract: A pet enclosure and waste tray system includes a rectilinear cage, an detachably integrated waste pan removably attached to the bottom portion of the cage, a molded waste tray into which the combination cage and waste pan may be nested, and a dolly upon which the waste tray securely fits. The rectilinear cage has a movable rectilinear section capable of being swung up and away from the cage to facilitate removal of enclosed pets. Nesting material may be introduced into the waste pan which supports and is spaced from the bottom portion of the cage. Due to the proximity of the waste pan to the wire mesh of the bottom of the cage, the nesting material penetrates the cage for the occupant's use. A continuous shoulder along the inside of the waste tray is dimensioned such that the cage is supported by the shoulder when nested within the waste tray. The waste tray has a downwardly curled upper lip receivable on railings extending upward from the dolly to securely support the tray-pan-cage combination.

Abstract: A go-kart construction uses a unibody construction wherein the body serves as a part of the suspension as well. The molded body is made from a flexible yet resilient material such as fiberglass or a suitable plastic such that it has sufficient flexion about a longitudinal axis to allow some twisting deformity without sagging when a passenger is supported in the vehicle. The forward suspension is mounted only to the forward portion of the molded body and includes a transverse member on which vertical bearings for the steerable guidance wheels are mounted, however, the transverse member is connected to the flexible body only by a pair of longitudinally extending members which are freely rotatably connected to the transverse member at their forward ends.

The bottom of the container is raised relative to the bottom of the side walls to promote water drainage. The side walls of the container have a plurality of holes therethrough to allow air flow so that the rode can adequately dry. An annular ring of soft rubber is affixed along the bottom of the side walls to prevent slippage of the container along the surface of the boat.

Abstract: Apparatus for preparing packaging materials for use in shipment of heat sensitive materials, utilizes a hydration module, a freezing module, and a delivery module. Rolls of superabsorbent polymer based refrigerant media in the form of a continuous web of a selected length and width are maintained in dry storage. These may be cut to size along the web material which separates cells containing the super absorbent polymer or may be precut by the manufacturer into pads of desired sizes. The web or pad is advanced into the hydration module which comprises a dip tank or spray system to provide an adequate supply of hydrating fluid to the superabsorbent polymer. The absorbed fluid fills the cells of the web. The hydrated web is then conveyed into a freezing chamber having a temperature of -10 degrees Fahrenheit, or lower, where the fluid absorbed within the cells freezes. The frozen material then exits the freezing chamber.
