Abstract: A method of playing a wagering game comprises receiving a wager, and generating a randomly selected first outcome of a first wagering game, the first outcome comprising a first plurality of symbols arranged in a first matrix. The method further comprises generating a randomly selected second outcome of a second wagering game, the second outcome comprising a second plurality of symbols arranged in a second matrix, and simultaneously displaying the first outcome and the second outcome on at least one display. The method further comprises detecting an occurrence of a triggering event, in response to the triggering event, copying a first special symbol occurring in the first outcome into the second outcome to yield a modified second outcome, and evaluating the first outcome and the modified second outcome for winning combinations of symbols.

Abstract: A method for manufacturing chip stack packages may include: providing at least two wafers, each wafer having a plurality of chips, and scribe lanes formed between and separating adjacent chips; forming a plurality of via holes in peripheral portions of the scribe lanes; forming connection vias by filling the via holes; establishing electrical connections between the chip pads and corresponding connection vias; removing material from the back sides of the wafers to form thinned wafers; separating the thinned wafers into individual chips by removing a central portion of each scribe lane; attaching a first plurality of individual chips to a test wafer; attaching a second plurality of individual chips to the first plurality of individual chips to form a plurality of chip stack structures; encapsulating the plurality of chip stack structures; and separating the plurality of chip stack structures to form individual chip stack packages.

Abstract: A process for producing lube basestocks involving solvent dewaxing a waxy feed to produce at least a partially dewaxed lube oil boiling range stream and then hydrodewaxing the partially dewaxed lube oil boiling range stream to produce a lube basestock.

Abstract: The invention relates to a method for analyzing a lubricating oil for low temperature properties. The method utilizes 2-dimensional gas chromatography (2D GC) to determine the amounts of paraffins and isoparaffins in the oil. In particular, the method analyzes for a particular isoparaffin fraction which is correlated to low temperature performance. The compositional information thus obtained is correlated with formulated oil Mini Rotary Viscometer (MRV) properties.

Abstract: A method for placing nitride laser diode arrays on a thermally conducting substrate is described. The method uses an excimer laser to detach the nitride laser diode from the sapphire growth substrate after an intermediate substrate has been attached to the side opposite the sapphire substrate. A thermally conducting substrate is subsequently bonded to the side where the sapphire substrate was removed.

Abstract: A test kit for determining the `total compost life`, and chemical stability of a moist compost sample, includes a transparent container for holding the compost sample, and a reactant mass, located within the container in the space not occupied by the compost sample. The reactant mass includes a pH basic reactant material, and a color change indicator material, responsive to pH changes in the atmosphere within the container. After the moist compost sample is charged into the container, the container is sealed and allowed to remain undisturbed for a prescribed time period, e.g., about three (3) hours. During this time, carbon dioxide (CO.sub.2) and volatile organic acids are emitted from the sample into the space surrounding the chemically reactant mass. The pH basic reactant chemically reacts with the emitted carbon dioxide (CO.sub.2), in ionic form, or the emitted volatile organic acids, so as to produce a color change. The nature of the color change is an indication of the carbon dioxide (CO.sub.

Abstract: Measurements of acids in air can be greatly falsified by the content of carbon dioxide in the air in spite of the low solubility of carbon dioxide in water and its low dissociation constant. When the measurements are made after a simple absorption of the acid residues in the air in an absorption solution. The air separated from the absorption solution on its way to measurement is cleaned of carbon dioxide by exposure to silica gel and soda-lime and then is used to clean the absorption solution of carbon dioxide in a similar exposure of air to the liquid. The measurement of the acidity of the solution thus cleaned of carbon dioxide provides reliable measurements of strong acid residues in air and can be carried out on a continuous basis.

Abstract: Method for the determination of the content of solid carbon compounds in soil samples, particularly in humus soils, by converting the solid carbon compounds with a reactant into carbon dioxide and conveying the carbon dioxide gas into an analyzer. To reach the reaction temperature, metal particles are added to a specified amount of the dry, milled soil sample and the dry matter is heated inductively in the presence of the reactant to the reaction temperature.

Abstract: A method of geochemical prospecting for buried sulphur mineralization which comprises collecting relatively organic free soil samples and determining the carbon isotope composition of the carbonate fraction.
