A method for processing a cryptographic operation request includes receiving, at a hardware security module (HSM), the cryptographic operation request including a cryptographic key and at least one authorization token, determining, by the HSM, whether an access control list (ACL) associated with the cryptographic key of the cryptographic operation request is authorized to govern access to the cryptographic key, and validating, by the HSM, the at least one authorization token. When the at least one authorization token is valid and the ACL is authorized to govern access to the cryptographic key of the cryptographic operation request, the method includes processing, by the HSM, the cryptographic operation request.

A composite material includes a cementitious composition and a plurality of fibers disposed in the cementitious composition. Each of the plurality of fibers includes a plastic component. Each of the plurality of fibers further includes a surfactant and a metal oxide, each independently heterogeneously dispersed throughout each of the plurality of fibers. A method of forming the composite material includes the step of combining the plastic component, the surfactant, and the metal oxide, to form the plurality of fibers. The method further includes the step of disposing the plurality of fibers in the cementitious composition to form the composite material.

A bowling ball is made with a shell and a core of different compositions, with the core having a greater density than the shell so that the finished ball will have a predetermined weight; and the core also having a maximum dimension along an axis passing through the top of the ball where the finger holes are to be drilled, and a minimum rotational inertia around the same axis. The core is temporarily supported on a pin while the shell is cast around it, and the hole left by the pin is filled with a material of distinctive appearance to designate the top where finger holes should be drilled.

Bowling ball

A bowling ball has a surface made from a material containing a minor quantity of functionally terminated liquid elastomer combined with a major quantity of resin-forming material reactive with the functional end groups of the elastomer, and has a greatly enhanced coefficient of friction against ordinary bowling lane surfaces, permitting superior control of the path of the ball and therefore better scores by the bowler. Such surface compositions are preferably made from a liquid polyester resin of the type which is hardenable by a peroxide, with addition of a liquid vinyl-terminated diene polymer or copolymer in a quantity amounting to about 10% to 35% of the mixture.
