Abstract: It is disclosed an arrangement of a rotor and at least a blade. The blade includes a root, a platform and an airfoil. The rotor includes a seat for the root. The root has side walls which complement side walls of the seat and axial walls between the side walls. A chamber is provided between the root and the rotor. A shank cavity is provided between the root and the platform. A lock plate facing at least an axial wall is connected to the rotor and the blade. The lock plate has at least a slot on a side facing the root.

Abstract: The invention relates to a rotor shaft adapted to rotate about a rotor axis thereof. The rotor shaft includes a rotor cavity configured concentrically or quasi-concentrically to the rotor axis inside the rotor shaft, and a plurality of cooling bores extending radially or quasi-radially outward from the inside to an outside of the rotor shaft. Each cooling bore having a bore inlet location and a distal bore outlet portion, the respective bore inlet location being adapted to abut on the rotor cavity. At least one side or part-side of the cooling bore inlet location is provided with an asymmetric edge fillet in order to maximize the wall thickness between two adjacent cooling bores.

Abstract: The present invention relates to a rotor assembly for a rotary machine such as a gas turbine. The present solution provides a sealing wire located inside a groove engraved in the rotor body. The sealing wire is responsive to radial centrifugal forces acting during normal operation of the machine, and moves radially in the groove until a sealing configuration is achieved such to prevent damaging hot leakage towards machine components.

Abstract: A retractable trailer decking system comprises a retractable decking configured to extend from a retracted position, along a pair of rails, to one of a plurality of extended positions. Each of the plurality of extended positions comprises a different length of usable retractable decking. In each of the plurality of extended positions, the retractable decking is configured to divide at least a portion of a cargo storage area into an upper cargo storage area and a lower cargo storage area, and a top surface of the retractable decking is configured to support cargo for storage in the upper cargo storage area.

Abstract: The present invention is directed to a method of reducing the nicotine content of a tobacco plant to less than addictive levels. The method includes the step of administering to the tobacco plant an effective amount of a nicotine reducing agent sufficient to reduce the level of nicotine in the tobacco plant so that the resulting nicotine content in the plant is reduced to a level wherein a tobacco product produced from the plant will yield a non-addictive level of nicotine in the central nervous system blood plasma of the user. The present invention is further directed to tobacco plants prepared by the method.

Abstract: Cut tobacco used for processing cigarettes or other smoking articles is reacted with an agent such as an oxidant or subject to an extraction/removal process for a suitable period of time, dependent upon the nicotine content, the oxidant employed and the reaction temperature or extraction condition, or distillation, such that the nicotine embedded in the leaf is then converted into nicotinic acid or niacin. Sufficient conversion or extraction or distilled is allowed to occur so that either no nicotine or only a minimal amount of free nicotine remains in the smoking article. Upon intake into the lungs and hence the blood stream of the smoker or other tobacco user, the smoker or tobacco user will result in a blood plasma content of nicotine ranging from 0 to less than about 5 nanograms per milliliter of blood plasma. This effectively insures that the addictive process in smoking or other tobacco intake cannot he initiated or maintained. Nicotinic acid or niacin is not an addictive component of the tobacco.
