Title: Systems and methods for dynamic bandwidth allocation for addressable content
Inventor: HABERMAN SETH
IPC: H04J3/16
Filed: 2009-07-30
Abstract: Systems and methods for push-based dynamic bandwidth allocation deliver addressable, advertising content in a digital network. Bandwidth is allocated on a push basis in response to receiving a cue tone from a broadcast stream. The cue tone contains data indicating an addressable break. A portion of bandwidth is then allocated to an addressable content stream based on the data of the cue tone. The addressable content stream is then streamed to a receiver during the addressable break and the receiver is tuned from the broadcast stream to the addressable content stream for the duration of the addressable break. The additional bandwidth is de-allocated at the end of the addressable break.

Abstract: An injection apparatus for injecting hot plastics material into an injection mold has an actuator section forming an actuator chamber and a nozzle member connected to the actuator section and extending to a nozzle tip having an injection aperture. The nozzle member includes an injection passage system for conducting the hot plastics material to the injection aperture. An elongate valve pin extends through a guide passage in the nozzle member and is movable between open and closed positions. A piston is connected to this pin, is slidably mounted in the actuator chamber and moves the valve pin between the open and closed positions. The piston and actuator section are machined to close tolerances so as to form a micro-gap between the wall of the piston and the wall of the chamber thereby avoiding fluid seals. The actuator is able to operate at temperatures ranging between 200 and 400 °C.

Abstract: Natural organic-containing substrates such as leonardite, lignite, peat, shale, sediment and soil are treated with alkaline or suitable chelating agents as extractants for organic matter in the nature of soluble fulvic and humic acid fractions . The mixture containing naturally occurring substances and extractant is then transferred to a centrifuge to produce a sediment or settled phase and a supernatant phase. The yield of organic matter found in the supernatant phase following centrifugation is significantly greater than the corresponding yield obtained when the mixtures are allowed to settle under gravity in the absence of centrifugation.

Abstract: The invention generally relates to the field of treating fine tailings, such as oil sand fine tailings. More specifically, it relates to methods for drying fine tailings by providing a deposition cell with a downward sloped bottom surface, and depositing flocculated fine tailings at the head of the cell to form a deposit as a lift extending down the cell. The lift has a built-up area and a thin lift area. The method also includes plowing the deposit while wet to spread the flocculated fine tailings from the built-up area toward the thin lift area, to promote drying.

Abstract: The invention relates to a rock-destroying tool used for drilling oil and gas wells, particularly for drilling angled and horizontal wells and rocks represented by alternating interlayers of different hardness. The technical result consists in improving controllability whilst at the same time increasing the vibration-resistance of a PDC bit by using a special composite coating and adjusting the degree of protrusion of the cutter above this coating.  The blade-type drill bit comprises a body with a connecting thread, a central channel and outlet openings for flushing liquid, and blades provided with polycrystalline diamond (PDC) cutters. The surface of the blades is equipped with a composite coating having a different degree of wear resistance over the thickness thereof, wherein the resistance of the composite coating to abrasive wear increases in the direction away from the outer surface towards the lower-lying layers, and the magnitude of the projection of the cutters close to the centre of the drill bit above the surface of the composite coating is less, as is known per se, than that required for drilling the most solid rocks in a given geological profile.

Abstract: Separating a mixture comprising at least two solid materials comprises transporting the mixture into a plenum, introducing air into the plenum, removing a heavier fraction of the solid materials from the plenum, removing air having a lighter fraction of the solid materials entrained therein from the plenum, removing the lighter fraction of the solid materials from the air that is removed from the plenum, filtering the remaining air, and re-circulating the air back to the plenum. Valves at the locations where material is introduced to and removed from the system can prevent air flow therethrough while allowing the materials to pass. The air can be introduced into the plenum at an angle with respect to the pathway in which the heavier fraction of the materials falls through the plenum, thereby avoiding damage to a screen that diffuses the air being introduced into the plenum.
