Abstract: A loading and transport device for all terrain vehicles. The loading and transport device loads two ATVs into a pickup bed by the use of a folding track that folds into an A frame shape by use of a jack. The ATVs are attached to the frame, and are transported in a generally vertical position. Loading involves unfolding the ATV racks, one of which reaches the ground. A winch is used to pull ATVs from the ground onto the ATV racks, and to lower them to the ground again.

Abstract: The current invention is apparel such as a glove to be used for sports and other uses. It has a core temperature device that may generate heat or cold with heat absorption material to absorb the heat as well as a number of temperature distribution systems to transfer the heat/cold. It would have a water repellent 2nd layer. It would have a one top flap and a net. In operation the wearer would insert a heating pad into the net of the top flap then sealing the top flap to the bottom half with Hook and latch fastener. The user would then apply pressure (with activity) to the core piece, releasing the stored air from the core heating device into the entire glove.

Abstract: A slide lock includes a slide lock base having a plurality of grip element openings; a slide lock handle carried by the slide lock base and positional in a released position and a locked position relative to the slide lock base; and a plurality of grip elements carried by the slide lock handle and disposed in the grip element openings, respectively. The grip elements are retracted in the grip element openings, respectively, when the slide lock handle is in the released position and the grip elements protrude from the grip element openings, respectively, when the slide lock handle is in the locked position.

Abstract: An apparatus and method relating to screening radioactive waste are disclosed for ensuring that at least one calculated parameter for the measurement data of a sample falls within a range between an upper limit and a lower limit prior to the sample being packaged for disposal. The apparatus includes a radiation detector configured for detecting radioactivity and radionuclide content of the of the sample of radioactive waste and generating measurement data in response thereto, and a collimator including at least one aperture to direct a field of view of the radiation detector. The method includes measuring a radioactive content of a sample, and calculating one or more parameters from the radioactive content of the sample.

Abstract: Embodiments of a system, method, and apparatus for predicting and reducing tracking by roller cone bits by adjusting compact spacing are disclosed. Different pitches between adjacent compacts or teeth provide a cone row that is substantially less likely to track. A given row on a cone may include compacts that are arrayed at a single pitch in a contiguous group for approximately half of the row. The remaining approximately half of the row includes alternating pitches. This configuration enables anti-tracking behavior without very wide spaces and consequent breakage and wear seen in prior art anti-tracking pitch schemes.

Abstract: A rotary tool for drilling subterranean material is disclosed. The rotary tool includes a tool body having a distal crown end comprising a circumferential series of raised cutting blades with recessed junk slots therebetween. Cutting elements are located proximate a leading peripheral edge of the raised cutting blades and cutting control structures are located interiorly of the cutting elements at a leading surface of an adjacent junk slot. Cutting control structures are releasably secured to the tool body in the adjacent junk slot whereby a used rotary tool is refurbishable by removing worn cutting control structures without degradation to the tool body and replacing the worn cutting control structures by installing new cutting control structures in the worn cutting control structures' locations.

Abstract: A motorcycle features a frame that includes a center tubing member that has front and rear end portions, a lower part in between the front and rear portions, the center tubing member having an overall length and occupying a plane. A plurality of laterally extending tube sections each have a length that is shorter than the length of the center tubing member, each shorter tube section having first and second ends that are connected to the center tubing member at spaced apart positions. The laterally extending tube sections include a first and a second plurality of shorter tube sections, the first plurality being connected to the center tube at a position in front of the second plurality of the shorter tube sections. A steering assembly includes a front fork, the steering assembly being pivotally attached to the front end portion of the center tube at a provided pivotal connection. A front wheel is carried by the front fork.

Abstract: A lifting and telescoping dolly for facilitating the moving of bulky objects into and out of attics by one operator acting alone. The collapsible dolly opens into a self-supporting A-frame with four support points. It has wheels and a brake system for positioning the dolly beneath an attic entry. From ground level a winch elevates the telescoping upper part of the dolly frame into the attic where it is firmly supported. From the attic a second winch elevates the load into the attic.

Abstract: A method is provided for generating an indicator of potential bit abrasion in a particular wellbore. Forensic wellbore data is obtained from at least one previously drilled wellbore which is determined to be comparable to the particular target wellbore. Typically, the comparable wellbore comprises an “offset” wellbore which is proximate the target wellbore, and which has similar geologic features. An inference engine computer program is provided which consists of executable program instructions. It is adapted to utilize a plurality of wellbore parameters, including the forensic wellbore data. The inference engine includes at least one rule matrix which defines a plurality of fuzzy sets. These fuzzy sets establish correspondence between the plurality of wellbore parameters and the indictor of potential bit abrasion. The inference engine computer program is loaded onto a data processing system. At least the forensic wellbore data is supplied as an input to the inference engine computer program.
