Abstract: A rotorcraft has a fuselage, an engine disposed substantially laterally centrally relative to the fuselage, and an air intake system (AIS). The AIS has a first duct configured to provide streamline air flow, a second duct configured to provide streamline air flow, and a combining section configured to receive streamline air flow from each of the first duct and the second duct. The combining section is further configured to output streamline air flow.

Abstract: Systems, methods and apparatus for providing and conducting a side or secondary wagering game with the underlying game of Roulette, which includes receiving a wager relating to the secondary wagering game, wherein the wager is resolvable after a preset amount of random Roulette outcomes have been obtained, generating the preset amount of random Roulette outcomes, storing each random Roulette game outcome of the preset amount, comparing the stored outcomes with preset criteria relating to the appearance of a pattern of indicia associated with Roulette outcomes, providing a payout corresponding to the wager if the preset criteria is satisfied and collecting the wager if the preset criteria is not satisfied.

Abstract: Methods of dissolving copper into electrolytic solutions, such as solutions comprising nitrogen compounds, by supplying an anodic current to a copper or copper-containing metal that is in contact with an electrolytic solution comprising a nitrogen compound (such as 2-hydroxyethylamine) and carbon dioxide. Anodic current may be provided by, for example, galvanic coupling with a material having a more positive reduction potential in the electrolytic solution (or given the system of electrolytic solutions) than copper, and/or by applying an impressed anodic current to the copper or copper-containing metal. Separate reaction vessels may be employed to house a first copper metal and a second cathode metal, as well as the electrolytic solutions associated with each.
