  • Patent number: 9389271
    Abstract: In a method for detecting disruptions proximate to an underground conduit, at least one signal carrying cable is positioned along a length of the conduit and between the conduit and a ground surface. At least one cable engaging member is connected to spaced apart locations on the at least one signal carrying cable to extend laterally outward of the at least one signal carrying cable. Each of the at least one cable engaging members is configured to transmit a force to the at least one signal carrying cable when impacted by an external force. A monitoring signal is provided to the at least one signal carrying cable, and a reflected monitoring signal is received in response to the supplied monitoring signal. One or more properties of the reflected monitoring signal are compared to one or more corresponding properties of a predicted reflected monitoring signal.

  • Patent number: 9233884
    Abstract: This invention is for a catalyst for conversion of hydrocarbons. The catalyst is a germanium zeolite, such as Ge-ZSM-5, on which at least two metals, platinum and at least one other metal selected from Group 7, Group 8, Group 9, Group 10 and tin, are deposited on the germanium zeolite. Examples of the other metal are iridium, rhenium, palladium, ruthenium, rhodium, iron, cobalt and tin. The catalyst is prepared by synthesizing a germanium zeolite; depositing platinum and at least one other metal on the germanium zeolite; and calcining after preparation of the zeolite, before depositing the metals or after depositing the metals. The catalyst may be used in a process for the conversion of hydrocarbons, such as propane to aromatics, by contacting the catalyst with a hydrocarbon stream containing alkanes, olefins and mixtures thereof having 2 to 12 carbon atoms per molecule and recovering the product.

  • Patent number: 9011235
    Abstract: A multi-opportunity, risk vs. reward, playfield-style gaming platform grants players the ability to evaluate gaming situations and decide whether to risk current assets for greater rewards throughout the course of a game. Players have multiple opportunities to make risk versus reward decisions that ultimately affect the financial outcome of game play. Positive impact squares, negative impact squares and indifferent impact squares are assigned to the game playfield though the software platform based upon manufacturer and casino specified odds for each “Coin-In” credit level and value of game play. A status and information area legend is updated through the software platform and reports important game play information to players, allowing them to make more informed decisions throughout the course of their gaming experience.

  • Publication number: 20140175002
    Abstract: An exfiltration apparatus for removing contaminants from a fluid includes a housing, a filter portion positioned within the housing, and a particulate collecting member. The housing defines a fluid flow path extending from a fluid inlet disposed on a first side of the housing to a fluid outlet disposed on a second side of the housing. The particulate collecting member is disposed within the housing between the fluid inlet and the filter portion. The particulate collecting member includes a recessed particulate collecting portion proximate the filter portion and a raised apertured portion proximate the fluid inlet. Fluid flowing along the fluid flow path passes through the particulate collecting member and through the filter portion before exiting through the fluid outlet.

  • Patent number: 8534035
    Abstract: A high through-put cotton harvesting system for selectively harvesting cotton from a plurality of selected cotton plants in a field, wherein the system includes a self-propelled mobile platform that is structured and operable to be driven through a field of cotton, and a compressor disposed on the mobile platform. The system additionally includes a plurality of plant picker assemblies that are extendable from the mobile platform. Each plant picker assembly is structured and independently operable to utilize a vacuum force, generated via the compressor, to extract cotton bolls from one or more cotton plants growing in the field as the mobile platform is driven through the field and deposit the extracted cotton bolls into a selected collection receptacle.
