Abstract: A process for recovering diamondoid compounds from hydrocarbonaceous minerals and/or from deposits left by such minerals in equipment or otherwise, which comprises dissolving diamondoid compounds in an aromatic distillate fuel oil; extracting aromatics from the solution; and separating diamondoid compounds from the raffinate of the extraction.

Abstract: A process for recovering diamondoid compounds from a fluid mixture thereof with other hydrocarbonaceous compounds which comprises contacting said mixture with a porous solid, for example, a zeolite, having pore opening large enough to admit said diamondoid compounds thereinto and small enough so that at least 50% of the external atoms of said diamondoid compounds are capable of simultaneously contacting the internal walls of the pores of said solid under conditions conducive to absorption of diamondoid compounds by said solid; and then desorbing the absorbate comprising diamondoid compounds from said solid absorbant.

Abstract: According to this invention, substantially hydrocarbonaceous fractions comprising diamondoid compounds are peculiarly suitable for separation by a thermal gradient diffusion process. Applicability of this process to this service is dependent upon the fact that the diamondoid compounds exhibit a large change in viscosity relative to temperature, that is, their viscosity goes down significantly per degree of increase in temperature.

Abstract: A process is disclosed for extracting diamondoid compounds from a hydrocarbon gas stream. The process includes two stages, each of which alone is effective to remove diamondoids from a hydrocarbon gas stream. The first stage comprises contacting the diamondoid-laden hydrocarbon gas with a suitable solvent to preferentially dissolve the diamondoids into the solvent. Diesel fuel is the preferred solvent for this first stage. The second stage comprises sorbing diamondoids from the diamonoid-laden hydrocarbon gas with silica gel. The most preferred embodiment of the invention is a serial process in which a diamondoid-laden gas is first treated in the solvation stage and the partially purified gas is further resolved in the silica gel sorption stage. The invention still further includes a process for segregating adamantane and diamantane when both are separated from a hydrocarbon gas stream.

Abstract: The present invention is directed to an improved rim or a high-performance rotary inertial energy storage device (flywheel). The improved rim is fabricated from resin impregnated filamentary material which is circumferentially wound in a side-by-side relationship to form a plurality of discretely and sequentially formed concentric layers of filamentary material that are bound together in a resin matrix. The improved rim is provided by prestressing the filamentary material in each successive layer to a prescribed tension loading in accordance with a predetermined schedule during the winding thereof and then curing the resin in each layer prior to forming the next layer for providing a prestress distribution within the rim to effect a self-equilibrating compressive prestress within the windings which counterbalances the transverse or radial tensile stresses generated during rotation of the rim for inhibiting deleterious delamination problems.

Abstract: The inertial energy storage device of the present invention comprises a composite ring formed of circumferentially wound resin-impregnated filament material, a flanged hollow metal hub concentrically disposed in the ring, and a plurality of discrete filament bandsets coupling the hub to the ring. Each bandset is formed of a pair of parallel bands affixed to the hub in a spaced apart relationship with the axis of rotation of the hub being disposed between the bands and with each band being in the configuration of a hoop extending about the ring along a chordal plane thereof. The bandsets are disposed in an angular relationship with one another so as to encircle the ring at spaced-apart circumferential locations while being disposed in an overlapping relationship on the flanges of the hub. The energy storage device of the present invention has the capability of substantial energy storage due to the relationship of the filament bands to the ring and the flanged hub.

Abstract: Machine tools utilized in precision machine operations require tool support structures which exhibit minimal deflection, thermal expansion and vibration characteristics. The tool support structure of the present invention is a graphite fiber reinforced composite in which layers of the graphite fibers or yarn are disposed in a 0/90.degree. pattern and bonded together with an epoxy resin. The finished composite possesses a low coefficient of thermal expansion and a substantially greater elastic modulus, stiffness-to-weight ratio, and damping factor than a conventional steel tool support utilized in similar machining operations.

Abstract: The present invention relates to a filament wound spherical structure comprising a plurality of filament band sets disposed about the surface of a mandrel with each band of each set formed of a continuous filament circumferentially wound about the mandrel a selected number of circuits and with each circuit of filament being wound parallel to and contiguous with an immediate previously wound circuit. Each filament band in each band set is wound at the same helix angle from the axis of revolution of the mandrel and all of the bands of each set are uniformly distributed about the mandrel circumference. The pole-to-equator wall thickness taper associated with each band set, as several contiguous band sets are wound about the mandrel starting at the poles, is accumulative as the band sets are nested to provide a complete filament wound sphere of essentially uniform thickness.
