摘要:
A bleed air duct that preferably includes an inlet section configured to include a flush scoop and a louver. The louver is located and configured such that in the desired operating flow range of the duct, the fluid entering the flush scoop is disturbed and as a result creates a low pressure region downstream of the louver. The low pressure region substantially eliminates the generation of any pressure pulses and acoustic resonance also known as Helmholtz resonance.

An improved trash container having a base, a rear partition wall, and a front partition wall hingedly attached to the base to enable the front partition wall to pivot and rotate forward away from the rear partition wall. The trash container further incorporates a bracket member that connects the front partition wall and the rear partition wall, enabling the front partition wall to transition amongst a closed position, an extended position and a releasing position. In a closed position, the base, front partition wall and rear partition wall are connectively aligned and together define an internal cavity for holding a trash bag. In an extended position, the front partition wall is pivoted forward of said base and separated from direct contact with the rear partition wall to enable efficient and hassle-free removal of a filled trash bag from the container.

Described herein are a method and apparatus for executing a draw-type lottery game between a plurality of players and a dealer. The draw-type lottery game includes a plurality of subgames and each of the subgames includes at least one hand of a blackjack-type game. The method includes, for each hand of each of the subgames, using a central computer system to generate for each of the players a player hand; to generate for the dealer a dealer hand; to compare each player hand to the dealer hand to determine whether the player or the dealer has a better blackjack hand; and to identify each player who has a better blackjack hand than the dealer as a winner of the hand. For each of the subgames, the central computer system determines a winner of the subgame based on the winner of the at least one hand of the subgame. The apparatus includes the central computer system, a plurality of remotely located terminals communicatively coupled to the central computer system; and a plurality of lottery displays communicatively coupled to the central computer system.

A system and method of using a variable geometry ejector for a bleed air system using integral bleed pressure feedback which utilizes a minimal amount of high-pressure air, thus improving the overall engine cycle performance and is easily adaptable to a multitude of different engine types. This is accomplished through the use of a variable ejector using downstream pressure feedback to control the flow and pressure.

Apparatuses are provided for reducing noise generation from a dead ended conduit in a gas turbine engine. In particular A scooped bellmouth is provided that comprises a bellmouth within a surface having an outer perimeter an inner perimeter and a ramp diverging from the surface at a first end, the ramp extending radially through the outer perimeter of the bellmouth at a second end. The ramp diverts an airflow away from the bellmouth thereby preventing the development of a low pressure area at the bellmouth without affecting the efficiency of the gas turbine engine.

The present invention provides methods, compositions, apparatus, and kits for assessing glycoforms of proteins as a biomarker for disease. A purified recombinant form of lectin is used as a detector molecule to specifically label target sugars expressed in disease states. The high affinity of recombinant lectin allows for automation of assays that would be used in the diagnosis of diseases such as, but not limited to, cancer or liver disease.

A backstop for a street hockey goal comprising left and right stanchions with a net fastened therebetween with a strut fastenable to a hockey goal for supporting the net in a deployed position. Once deployed the net exceeds the height of the hockey goal and extends beyond said goal to the left and right. The base of each stanchion matingly engage each other when in the folded position with the net having a partial slit vertically extending with fasteners that attach to their respective stanchions when in the folded position.
