Abstract: A resilient sleeve for a beverage container is made from a continuous web of a fabric extending between distal and proximal ends thereof. A substantially linear base is provided at the proximal end. First and second sides extend outwardly from the opposite ends of the base. Two substantially symmetrical trapezoidal regions are formed at the distal end of the web, wherein each trapezoidal region is formed by an outer side positioned at a first predetermined angle to the first side and an inner side positioned at a second predetermined angle to a longitudinal axis of the web portion. A V-shaped cut out portion is formed at a central area of the web by the inner sides of the first and second trapezoidal regions. Width of the web portion corresponds to a circumference of the sleeve and length of the web portion corresponds to an axial length of the sleeve.

Abstract: A driveshaft assembly for a downhole motor comprises a housing and a driveshaft rotatably disposed within the housing. The driveshaft has a central axis and a first end. Further, the driveshaft assembly comprises a driveshaft adapter having a first end coupled to the first end of the driveshaft with a universal joint. The first end of the driveshaft adapter includes a counterbore. The first end of the driveshaft and the universal joint are disposed in the counterbore. Still further, the driveshaft assembly comprises an end cap disposed about the driveshaft and coaxially coupled to the adapter. Moreover, the driveshaft assembly comprises a seal boot disposed about the driveshaft and adapted to restrict fluid flow through a annular gap positioned between the driveshaft and the end cap. The driveshaft assembly also comprises a locking assembly adapted to restrict the end cap from moving axially relative to the adapter.

Abstract: Methods for verifying satisfaction of prognostic algorithm requirements for a component of a certain device of interest are provided. A method according to an example of an embodiment of the invention can include providing a prognostic algorithm requirements statement for a preselected component contained in each of a plurality of a certain type device, receiving field data indicating a number of premature component failures and a total number of replacements including both due to premature failures and scheduled maintenance, determining a probability density function providing a probability of failing to replace the prematurely failed components, determining a confidence value indicating a level of confidence that failure avoidance requirements provided in the prognostic algorithm statement are being met, and verifying whether or not the prognostic algorithm requirements provided in the prognostic algorithm requirements statement are being satisfied according to a preselected minimum level of confidence.

Abstract: A method makes use of a minimally-shearing feeder mechanism supplying a desired flow of particulate solids mixture, with minimal to no sifting segregation to a desired location. The feeder methodology maintains a uniform concentration of each size of particle within the mixture.

Abstract: A method and apparatus enables testing of sifting segregation of a particulate solid mixture in a storage bin or hopper. The apparatus makes use of a convergently and divergently angled hopper for collecting the mixture. The apparatus further makes use of a minimally-shearing feeder mechanism supplying a desired flow of mixture, with minimal to no sifting segregation, to the angled hopper. A collection mechanism removes samples of the mixture from the angled hopper for analysis with minimal disruption of the particles of the mixture relative to each other. Thus, samples resulting from the testing apparatus, and corresponding method, are highly representative of mixture conditions within a larger storage hopper.

Abstract: A bed of particulate solids is fluidized in a test chamber to yield multiple test samples for subsequent evaluation of segregation effects. A controlled stream of gas enters the chamber in a series of flow rate cycles each progressively increasing to a maximum rate of gas flow and then decreasing, the maximum rate increasing for successive cycles. An indicating function is formed from measurements of corresponding rates of gas flow and pressure across the bed. Upon termination of the fluidization, multiple samples are sequentially extracted from a single space at the bottom of the test chamber.
