Abstract: A utility transport tractor having a cargo box above the rear axle with the operator's platform forward of the rear axle enabling additional seats to be included. To maintain the functionality of a conventional agricultural tractor, the cargo box tail gate and a portion of the cargo box floor can be raised to positions in which they both extend upwardly and forwardly toward the operator. In these positions, the three point hitch at the rear of the tractor is visible to the operator as is typically the case conventional agricultural tractors. The tail gate is mounted to the cargo box for rotation about multiple axes to pivot the tail gate to multiple open positions.

Abstract: The invention relates to a method for drying and degassing polyolefins in which the polymerization product leaving a polymerization reactor is brought into contact with a degassing medium and simultaneously decompressed. The degassing medium employed according to the invention is the monomer to be polymerized, which, in particular, flows through a decompression tank in a circulation process and which is preferably also enriched with ethylene or other low-boiling olefins in an amount in the range from 0 to 100 mol %, based on the total amount of circulating gas. A polymerization in an amount of up to 10%, based on the total polymerization conversion, takes place in accordance with the invention inside the decompression tank.

Abstract: A device for igniting a combustion in a combustion chamber of a gas turbine has a housing fitted with an end piece and with a head piece. Hitherto, an ignition conductor comes into contact with combustion air. Moreover, fragments of a partial ceramic insulation can lead to damage. To improve the quality of ignition, the ignition conductor and a gas conduit are disposed to run parallel to one another within a housing. The ignition conductor is surrounded by a protective sleeve, and an annular space between the ignition conductor and the protective sleeve is filled completely with a ceramic material. An annular disc serving as an ignition electrode is mounted on that end of the protective sleeve that projects into the head piece.

Abstract: In a steam power station, the condensate used as feedwater is preheated up close to the boiling temperature by means of partial steam mass flows from the turbine steam quantity. Due to the steam extraction, the following steam-turbine stages can draw less power from the steam fluid. To avoid the reduction in the power output at the following steam-turbine stages, provision is made for the waste heat from fuel cells to be used for preheating the condensate. Due to the preheating of the feedwater from the waste heat of the fuel cells and the associated increase in the steam quantity participating in the expansion, an increase in the efficiency of the steam process is achieved.

Abstract: A steering control system for a tracked vehicle includes an engine driven variable displacement steering pump which drives a hydraulic motor. A control system senses steering wheel position, vehicle speed, engine speed and forward/reverse vehicle direction. As a function of these sensed inputs, a control signal is generated and is used to control the swashplate angle of an engine-driven variable displacement pump which drives a steering motor which drives a differential track drive mechanism. The control system also determines a ratio of motor speed to vehicle speed and generates a powerboost signal when the ratio exceeds a threshold value. The powerboost signal is communicated to the engine controller which causes the engine to increase its power output. This modifies the engine fuel delivery curve based on the steering system power requirement and increases the power available for turning the vehicle.

Abstract: The lower draft link of a tractor three-point hitch includes a sensor to sense draft loads imposed on the draft link by an earth-working implement. Variations in the draft load cause variations in the pressure of the fluid in the sensor from a preselected pressure. A pilot-operated, load control valve is connected to the sensor and is shiftable in response to pressure above and below the preselected pressure to actuate a control mechanism. The control mechanism actuates a direction control valve for directing fluid to and from a hydraulic lift cylinder for respectively raising and lowering the draft link to adjust the implement so as to maintain the preselected pressure and thus maintain the desired draft load.
