Abstract: An architectural cast stone product for use in building construction has a unitary shell made of a molded cementitious material that partially surrounds and is affixed to a foam core. The architectural cast stone product has a mounting surface including an exposed surface of the foam core and an exposed surface of the shell. The architectural cast stone product is made by obtaining a front pattern having a desired surface configuration for the architectural cast stone product, obtaining a foam core, affixing the foam core to a backer, affixing the front pattern to the backer that together form a mold, pouring a cementitious material into the mold and into contact with the foam core, at least partially curing the cementitious material to form the architectural cast stone product, and removing the front pattern and backer from the architectural cast stone product. The architectural cast stone product may optionally be surface finished, such as by sanding or polishing, to yield a desired surface finish.

Abstract: A method and a computer program product that enable an existing operating system (OS) to provide a non-failure response to an application's reference to an OS service that is not currently defined/available within the existing OS. The loader of the OS responds to each reference to an undefined service by mapping the reference to an undefined service response utility (USRU). USRU is a specialized service designed to provide a response that a requested service is not yet available. When the OS loader detects that an application is referring to an OS service that is undefined, the OS loader resolves the reference to the USRU, which, when invoked returns an indication that the requested service is not yet available.
