Abstract: A process for forming algae-resistant roofing shingles comprises producing algae-resistant granules, and adhering the granules to a shingle stock material. The algae-resistant roofing granules are produced by a process that includes coating mineral particles with a clay-silicate binder including a metal oxide algaecide and small organic particles. The particles are heated to cure the binder, and the organic particles pyrolyse to form pores in the coating. The release of the algaecide is controlled by the structure of the granules.

Abstract: Cuttings from drilling through or into natural rock and/or soil can be incorporated into useful, high quality load-bearing structures such as vehicle roads and pads for deep drilling rigs. This process recycles a material previously regarded as valueless at best and often as a pollution hazard. The cuttings, optionally mixed with drilling mud and/or soil, are converted to the useful structures by pozzolanic and/or cementitious reactions after being mixed with suitable other materials and/or are bonded into the useful structures by asphaltic materials.

Abstract: Synthetic shingles are made and treated, such that upper surfaces thereof that are to be weather-exposed in the installed condition, are scuffed, abraded, or scraped in such a manner that different visual appearances occur between abraded zones and unabraded (or lesser abraded) depressions, to enhance the natural-appearing materials that the synthetic shingles are designed to resemble. The shingles and the abrading medium have motion relative to each other. The abrading medium may take on various forms, such as a roller, a brush, a pad, etc. Some portions of the upper surface of the shingle remain unabraded, preferably being those portions that are depressed relative to higher portions of the shingle. The shingle may be of a single layer construction, or a multi-layer laminate.

Abstract: A method for controlling a relational database system, wherein a query statement to be processed, which consists of keywords, is first analyzed by applying a recursive transition network (RTN) and then converted into control commands by the following steps: defining the RTN in a presetting step by forming independent RTN building blocks each having an inner, directed decision graph and optionally at least one recursive call function; forming an RTN building block-independent reference group, the elements of which refer to a residual decision graph with the first decision position removed; carrying out a reference processing step and running the residual decision graphs, which may prescribe the recursive call function; and generating an optimized access plan for the relational database system.
