Abstract: The sharpness or efficiency of cutting edges of blade rails or other blades used in mowing mechanisms is very rapidly lost on meeting a obstacle. The blade shape of this invention, presents a cutting edge including a series of adjacent parallel recesses transversely to the cutting edge on the top of the blade. This gives equidistant thin and complete material. A differentiation is made on the cutting edge between the protective material (full thickness) and sharp edges (recesses). Experience has shown that, on the encountering of an obstacle, the cutting edge (thin Material) is protected by the full material to its left and right which results in a long useful life with relatively constant cutting efficiency.

Abstract: A hay raking machine of the present invention for attachment to a tractor with a single point hitch has a lifting mechanism for lifting the hay raking machine above cut hay laying on the ground while keeping the rake arms substantially level to the ground.

Abstract: A drawing/false twist texturizing process capable of being implemented during the treatment of the yarn. During the treatment, the point of striction is localized during the drawing phase by bringing about an abrupt break or modification in the trajectory of the yarn while it is rising in temperature in the texturizing zone. This is achieved by pressing on a surface or element allowing the twist imparted by the false-twisting spindle to be taken back as far as the first feed system. The modification in the trajectory of the yarn is achieved in the actual oven either while the yarn is rising in temperature or in the vicinity of the zone where it reaches its optimum treatment temperature.

Abstract: In a method of operating a plant with staged combustion, the first combustion stage (1a) is operated with a fuel/air mixture (3) whose air coefficient is larger than the overall air coefficient of the combustion system. The hot combustion gases (5) from the first combustion stage (1a) are mixed with an additional fuel/air mixture (4) whose air coefficient is smaller than the overall air coefficient of the combustion system, before the further combustion in the second stage (2a) takes place. Since hot-gas backmixing is no longer required in the second stage (2a) for the flame stabilization, this combined mixture burns without the formation of further NOx emissions.

Abstract: A brake booster having a body in which a booster pressure sensor for detecting the internal pressure of an atmospheric pressure chamber is provided, and in which the operating state of a brake pedal is detected by a pedal sensor. Further, when the brake pedal is not depressed, the internal pressure of the negative pressure chamber is detected by the booster pressure sensor. In contrast, when the brake pedal is depressed, an atmospheric pressure is detected by the same booster pressure sensor. Namely, when the brake pedal is not depressed, the negative pressure chamber and the atmospheric pressure chamber communicate with each other and are thus shut off from atmospheric air. Therefore, the internal pressure of the negative pressure chamber is detected by the booster pressure sensor which communicates with the atmospheric pressure chamber. Moreover, when the brake pedal is depressed, the atmospheric pressure chamber communicates with atmospheric air.

Abstract: A manually operated in-line secondary master cylinder can be configured for use with any hydraulic system which accommodates multiple manual input forces, and which requires the secondary input device to operate independently of the primary input device. The secondary master cylinder can be placed directly in a primary system operating pressure line, where it has no effect on system operation until it is actuated. Unlike a conventional master cylinder, the device draws a very small amount of charging fluid directly from the primary system line due to its use of a split piston, free backflow and volume displacement approach.

The molded shell faces with its point the fluid flow that hits its outer side and may be used as a mixing element for gaseous fuel and air, as an air sprayer with flame-holder, as a mixing element for admixed air in combustion chambers, as a swirling element or as a shell-shaped air sprayer combined with a fuel film generator or a fuel pressure spraying nozzle.

Abstract: A gas turbine system in which substantially all of the compressed air from the compressor portion of the gas turbine is used to fluidize a bed of solid fuel, such as char, in a pressurized fluidized bed gasifier so as to produce a hot gas. The hot gas flows through a heat recovery steam generator so as to produce steam, which is expanded in a steam turbine so as to produce shaft power. A first portion of the hot gas from the heat recovery steam generator is expanded in the turbine section of the gas turbine so as to produce additional shaft power. A second portion of the hot gas from the heat recovery steam generator is then used to cool the turbine section of the gas turbine, after further cooling and filtering. Since none of the turbine cooling fluid is obtained by bleeding compressed air directly from the compressor, the mass flow of the hot gas flowing through the gasifier, and, therefore, the hot gas it produces is maximized, thereby maximizing steam generation in the heat recovery steam generator.

Abstract: An in-line valve flow controller for a Joule-Thomson cryostat. The controller has an in-line valve stem that is part of, and is collinear with, an actuation stem of the cryostat. Both the in-line valve stem and actuation stem sit in an orifice of the Joule-Thomson cryostat. This arrangement automatically positions the valve stem over its valve seat. The in-line valve flow controller integrates with a temperature dependent snap disk that is used to close the valve stem against the valve seat. Initial flow rate is determined only by the diameter of the orifice of the Joule-Thomson cryostat, and not by valve position. Bypass flow is aso set by the diameter of the orifice, which is not subject wear, and the valve stem prevents contaminates from clogging the orifice.

Abstract: A method for conditioning water vapor bearing compressed air for supply as conditioned air to an enclosure includes the steps of flowing the compressed air into a condenser-evaporator heat exchanger and then cooling the compressed air with a liquid evaporating refrigerant in the condenser-evaporator. Thus, the water vapor in the compressed air can become condensed liquid water available for subsequent separation to form a dehumidified air. The dehumidified air undergoes reheating with a vapor condensing refrigerant in a reheater-condenser such that the dehumidified air becomes a reheated air. The reheated air is then routed through a turbine to provide the supply to the enclosure. An apparatus is also provided for accomplishing the above steps and includes a condenser-evaporator heat exchanger capable of placing the compressed air in heat exchange relationship with a vapor cycle subsystem.
