Abstract: A structure of a circuitry substrate for securing an area from tampering is disclosed. The structure includes a circuitry substrate with at least one of a top tamper enclosure and a bottom tamper enclosure covering a component in a protected area of the circuitry substrate. The top and bottom tamper enclosures are adhesively bonded to a surface of the circuitry substrate, and a tear initiation site is added to a side of the perimeter of circuitry substrate bordering the protected area that includes at least one tamper enclosure, such that the tear initiation site is located and configured to enable propagation of a delamination of at least one internal layer of the circuitry substrate and a severing of a security circuit when a removal force is applied to the at least one of the top tamper enclosure and the bottom tamper enclosure.

Abstract: An abrading composition and a process for abrading factory pre-finished surface coverings, wherein the abrading composition comprises an effective amount of wear-resistant particles, a rheology modifier, and a solvent. This invention further relates to a process to abrade wood floor surfaces and factory pre-finished wood floor surfaces, as well as a process for refinishing a factory pre-finished wood floor using the abrading composition.

Abstract: A computer program provides for the display of window regions on a display screen whereby the content and size of one window region is controllable in two dimensions using means provided in another window region. A cursor device and a signal generation means is used to select the two-dimensional scrolling or resizing of a window region. Controls are also provided to move and terminate window regions. Upon termination, the configuration of window regions is saved on a data storage means for use when the window regions are re-displayed. Cursor movement can be restricted to the horizontal or vertical directions only.

Abstract: Multigrade lubricating oils blended from petroleum distillates and, if desired, a bright stock containing waxy or wax-like components and modified by the presence of copolymeric ethylene-higher alpha-olefins viscosity index improving agents have their low temperature performance markedly improved when said copolymer contains a minor weight proportion of ethylene by the addition of from about 0.15 to about 1, preferably 0.2 to 0.5, wt. %, based upon the total weight of said lubricating oil composition of a combination of pour point depressants comprising: (a) from about 0.05 to about 0.75 wt. % of an oil-soluble condensation product of a chlorinated wax of from about 10 to about 50 carbon atoms and a mono- or dinuclear aromatic compound; and (b) from about 0.05 to about 0.75 wt % of an oil-soluble polymer of C.sub.10-18 alkyl acrylate or methacrylate and/or an interpolymer of a vinyl alcohol ester of a C.sub.2 to C.sub.18 alkanoic acid and di(C.sub.6 -C.sub.18 alkyl) fumarate.
