Abstract: Thermal energy transmission from a cryocooler cold finger is enhanced by means of a high thermal conductivity material used for or placed adjacent the cold finger end cap. In addition, the actual or effective surface area contacted by the working gas proximate the endcap is increased, thereby increasing the convective heat transfer coefficient. These features permit the coolest gas expansion space in the cold finger to be provided within the highly thermally conductive end cap, unlike many conventional designs in which the cold finger of low thermally conductive metal forms the expansion space side walls and the endcap forms only the axially facing outer surface in contact with the cooled equipment. Having the expansion space built into the high thermally conductive end cap reduces the temperature drop between the load to be cooled and the gas (e.g., helium), thus increasing the thermodynamic cycle efficiency.

Abstract: One variation of a method includes: accessing a rendering of a model depicting features of a part; accessing a set of target features of the rendering and a function of the part, the function defining a constrained degree of freedom for the part; defining a set of datums intersecting a subset of target features that constrain the part according to the constrained degree of freedom; populating an engineering drawing with a set of projections of the rendering; annotating edges of the subset of target features in the set of projections with datum callouts; annotating edges of the set of target features in the set of projections with feature control frames; annotating a set of edges in the set of projections with the basic dimension callouts representing numerical dimensions relative to the set of datums and reference dimension callouts representing maximal dimensions of the part; and rendering the engineering drawing.

Abstract: A heavy truck tire is provided with a bead design that has a bead core and a reinforcement ply that wraps around a section of the bead core and has a return casing ply. Bead filler is present that has a portion radially outward from the bead core and axially inboard from the return casing ply. A stiffener layer is present that has a portion located outboard from the return casing ply. The bead has a first bead layer with a portion between the return casing ply and the stiffener layer, and a second bead layer that has a portion outboard from the stiffener layer. The stiffness of the first and second bead layers is 8 MPa to 14 MPa. The stiffness of the bead filler is less than the stiffness of the first and second bead layers.

Abstract: A tire having a radial carcass reinforcement, made up of a single layer of reinforcing elements anchored in each of the beads by being turned up around a bead wire, reinforced by a stiffener. In the sidewall of the tire, the profile of the outer surface of the tire is at a constant distance from the carcass reinforcement layer between the points F and A, and meets the outer surface of the bead at the point C, forming two successive circular arcs.

The decision engine determines a profile that comprises an order of execution and an optimization level for use during compilation of the plurality of applications. The profile is then used to schedule compiling and optimization of the applications.
