Abstract: A rotational coupling device may include a housing which may be coupled to a stationary coupler. The stationary coupler may be used to engage or couple the device to a machinery stand. A motivator shaft may be positioned on one side of the housing and a rotational drive shaft may be positioned on the other side of the housing. The motivator shaft and the rotational drive shaft may be operably connected together with a gear arrangement with rotation of the motivator shaft resulting in rotation of the rotational drive shaft that is of a reduced rate compared to the motivator shaft. The rotational drive shaft may be coupled or connected to the rotational assembly via a rotational coupler thereby allowing rotational motion provided by the motivator shaft to be transferred through the rotational drive shaft to the rotational assembly of the machinery stand to which the device is engaged.

Abstract: A blackjack competitive event is implemented between two playing card positions. A set of playing cards is used including 49 to 56 playing cards, wherein at least one 10 value-card is specifically marked with an indicator that the 10 value-card may have a value of 0 or 10 points. Two random playing cards are dealt to a player position and a dealer position. The player position and dealer position take additional random playing cards from the unique set of playing cards, counting specifically marked 10 value-cards as either 0 or 10, and electing to cease taking additional random playing cards when a total player position point count of 21 or lower is achieved. Winning is determined on the basis of which of i) the dealer position hand point count total and ii) the player position hand point count total being closest to a count of 21 without exceeding 21.

Abstract: A pig launcher/receiver includes a fluid distribution grid arranged above a floor of the pig launcher/receiver's barrel to define a fluid chamber between the floor and the fluid distribution grid. The distribution grid has a plurality of ports arranged to form jets that discharge at least a portion of the fluid which enters the fluid chamber. A predetermined number of the ports are inclined relative to vertical and in a direction opposite a closure door of the barrel. The fluid distribution grid, which is preferably semi-circular shaped, can be a permanent weldment, bolted on, or removable. When used in launching a pig, the ports provide a differential pressure that lifts the pig and overcomes friction as the pig moves forward. Because a number of the ports are blocked by the sealing elements (cup or disc) of the pipeline pig, the number of pigs residing in the launcher/receiver can be determined.

Abstract: A process of executing a keno-type wagering event wherein a processor recognizes. Provides two adjacent regions for display of two distinct distributional arrays. A first distributional array has 80 selectable alphanumerics in columns and rows, and a second distributional array has eight columns of 10 frames each forming four distinct pairs of linear arrays of frames for collecting ball drop outcomes. The processor recognizes degrees or numbers of correspondence along linear relationships between lines or columns in the first and second distributional arrays.

Abstract: A method of modeling relationships between e-mail users. The method includes extracting a record of e-mail exchanges between the users. The record is extracted from at least one of an e-mail server and an e-mail transfer agent. The data is extracted through a direct internet access protocol. The method includes filtering the record to produce relevant interaction data based on the e-mail exchanges between two users. Relevant interaction data includes a number of e-mail exchanges between the users and includes a ratio of source to target and target to source interactions. The method includes loading the relevant interaction data into a relationship modeling program, which assigns a weight to each of a plurality of characteristics of the relevant interaction data and provides a model of relationships between the e-mail users based at least in part on the weight of each characteristic. The plurality of characteristics comprises interaction volume.

Abstract: A game play on an electronically based system utilizes symbol collection outcomes along paylines to determine winning events in a virtual game. Even when the symbols used in the virtual game comprise or consist of playing cards displaying conventional ranks, suits and symbols, winning outcomes are determined only by accumulation of sets of symbols, without regard to linear order (straights and straight flushes) and random symbols within a suit (flushes). Accumulated symbols in an at least five symbols display game event as pairs, trips (three-of-a-kind), two pairs, full houses (three of one symbol plus two of a different symbol), four-of-a-kind and five-of-a-kind are determined to be winning events, while a flush, straight and even straight flushes may be or are required to be ignored. Optional and even preferred additional events are used in a draw poker variant (with playing card symbols or non-playing card symbols are used in an accumulated symbol gaming event).
