Abstract: A base rating number calculation determines a number rating providing a practical tool for assisting in the selection of foods best suited for healthy weight management. The rating tool is a component of a comprehensive health plan including food quality rating, formulating healthy weight management goals, calculating and reporting on progress in attaining goals and presenting informative and motivational visual displays illustrating the status of goal attainment.

Abstract: An Application implemented on a computing device. Algorithms in the Application convert information about the nutrient concentration in a measure of food into a single quality rating number for the food. Concentration values of specific nutrients in the food are determined using information about the weight of selected nutrients in a measure of the food.

Abstract: A drill string design methodology which utilizes a “comparative approach” in the selection of drill string components. The comparative approach in accordance with the present invention can lead to dramatic reductions in fatigue-related problems. In accordance with one aspect of the invention, a method is provided for establishing objective criteria for evaluating individual components of well construction equipment to determine the preferred component or collection of components to be used from the selection of components available. A plurality of quantifiable design parameters relevant to the issues of fatigue damage and failure of drill string components are defined, and an assessment of each of these parameters is made for two or more candidate components being considered for inclusion in the drill string. A comparison is then made between the candidate components' ratings, and a decision to include or exclude a candidate component is made based upon the results of such comparison.

Abstract: A gauge to evaluate the flatness, planar disposition, and location of the sealing surface of a rotary shouldered threaded connection, the gauge being adjustable and convertible to gauge either pin or box ends of different size connections, with multiple contact shoes engaging the connection threads to hold the gauge fixed relative to the thread pitch diameter and a device to measure distances from the pitch diameter to the shoulder face. In the method, the gauge is moved around the connection to obtain measurements from different circumferential locations to evaluate shoulder flatness and axial location and to examine the angular disposition of the plane of the shoulder face relative to the thread axis.

Abstract: A subsurface safety valve which is used to control the flow of well fluids through well tubings combines (1) the velocity valve principle of differential pressure and (2) a change in well tubing pressure to produce a closing force for the valve. A valve housing is connected into a well production tubing. A movable valve element is connected to the valve housing. In one position of the valve element flow of fluids through the valve housing is permitted and in another position thereof flow of fluids through the valve housing is prevented. The movable valve element forms with the valve housing a pressure chamber and larger and smaller differential areas. An inwardly protruding surface or flow bean is formed on the valve element. Fluids flowing through the valve housing cause a pressure differential across the flow bean. The flow bean is located between the larger and smaller differential pressure areas, the larger being above and the smaller below the flow bean.
