Patent DE-19505235-A1 (DE)
Title: Heating method for heating circuit with varying return flow temperatures using heat exchanger
Inventor: KREMER ROBERT
IPC: F24H9/12
Filed: 1995-02-16
Abstract: The method involves hot combustion gasses passing vertically through a heat exchanger (6) inside a hot water tank. Hot water is taken out of the top of the tank and the return flow is ducted back into the tank by a lower duct (13). A vertical baffle plate (15) is positioned in front of the return flow port to slow the return flow and to reduce the mixing effect with the hot water in the tank. This enables a temperature layer structure to be maintained in the tank for efficient heat transfer from the heat exchanger. The baffle divides the hot water tank into an inner section (16) containing the heat exchanger and a smaller outer section (17) in which the return water is slowed and is allowed to settle to its density level. With cool water layers at the bottom of the tank the bottom of the heat exchanger operates in temperatures below the condensation temperature of the combustion gasses enabling more heat to be extracted from the gasses.

Title: Control of car engine braking during freewheel phase
Inventor: ADAMIS PANAGIOTIS PROF
IPC: F16H61/21
Filed: 1995-03-04
Abstract: In a procedure for controlling the engine braking of a car, the presence or wish for a freewheel situation is deduced from the released gas pedal and passed to a computer. This then disengages the clutch between engine and gearbox, and stops the engine. When the pedal or the gear lever is moved to indicate the end of freewheeling, the computer restarts the engine and reengages the clutch. Engine braking is given (engine started and clutch reengaged) when the brake pedal is operated, without any movement of the gas pedal or gear lever. When the brakes have returned to their non- operated position for a certain length of time, the engine braking ceases and freewheeling returns.

Patent DE-19519247-A1 (DE)
Inventor: KIRSTEN GUENTER
IPC: F04C23/00
Filed: 1995-05-25
Abstract: The invention relates to a worm-drive compressor (10) with a main rotor shaft (18) on which are fitted at least one first and one second main rotor (14, 16), each of which meshes with a matching first or second sub-rotor (20, 22) on a rotor layshaft (24). To provide a hard-wearing, economically produced and highly efficient worm-drive compressor (10), the bearings of the rotor main and layshafts (18, 24) are matched to the compressed gas supply in such a way that the loads imposed on the shafts by the pressures produced are absorbed by radially operating bearings (40, 42, 44, 47) near the point at which they arise.
Patent DE-19521356-A1 (DE)
Inventor: HUMS ERICH DIPL CHEM DR
IPC: F02C3/20
Filed: 1995-06-12
Abstract: The invention provides a burner with a catalytic combustion chamber. The combustion chamber is substantially cylindrically widened in the direction of flow of a fuel and has a catalytically active coating on the walls facing the fuel to oxidize the fuel. The catalytically induced combustion of a fuel results in a particularly low nitrogen oxide content in the burner's exhaust gases. At the same time, the coating of the walls does not raise the flow resistance in the burner, unlike prior art primary measures to reduce nitrogen oxides. The use of the burner in a gas turbine therefore provides particularly high efficiency with low nitrogen oxide emissions. The invention can be used in all gas turbines.
Patent DE-19527531-A1 (DE)
Inventor: MATSUNO KOJI
IPC: G01P15/00
Filed: 1995-07-27
Abstract: A vehicle speed calculation system capable of calculating a reference speed of a four-wheel drive vehicle with high accuracy even when a four-wheel slip or lock occurs. The system uses a wheel speed sensor for each wheel and a longitudinal acceleration sensor. The speed signals corresponding to the lowest and highest wheel speeds are selected and their variation per unit time is calculated. An integrated value of the longitudinal acceleration signal is forcedly used for the calculation of the reference speed when the vehicle is not braked and the variation of the lowest wheel speed is negative, or when the vehicle is braked and the variation of the highest wheel speed is positive. <IMAGE>

Title: Self-steering control system for agricultural machines esp. combine harvester
Inventor: DIEKHANS NORBERT DR
IPC: A01B69/04
Filed: 1996-04-09
Abstract: The system has the agricultural vehicle equipped with position sensors, to locate items to be harvested, which provide analogue voltage signals to an electronic unit which then controls the direction and speed of the vehicle. The vehicle  (1) is automatically steered along the edge or perimeter (GK) of a cereal field (GF) by means of a position-sensing arrangement (OV) directing a beam (OST) along the perimeter. A signal (OS) is transmitted to a control unit (ST) as well as a speed signal (VS) from a front wheel (VR) of the machine.  A datum steering condition may be set manually at the control unit. A hydraulic steering control cylinder (LZ) is operated by left and right proportional valves (PVL,PVR) and moves the rear wheels (HR) and a wheel position sensor (RSS) sends a signal (RWS) to the control unit. The steering control valves are sprung to a closed position so that with no control signal steering is by the steering wheel (R). Proportional amplifiers (10,20) convert detected steering error signals to the steering control valves which then correct the direction of travel of the machine at a rate determined by the speed signal (VS).
