Patent DE-19646802-A1 (DE)
Inventor: HAMBERGER RALF
IPC: F27B1/16
Filed: 1996-11-13
Abstract: An operating method for a cupola melting furnace. Metal charging stock, alloying elements and energy carrying substances such as coke are added in the upper part (1) of the shaft. An oxidyzing medium such as air is added in the lower part (2) of the shaft. Additives such as alloying elements, metal chips, carbon, sand and dust of different types are introduced either individually or in combination into the melting section (5) in at least one first jet. Combustibles can also be charged into the first jet, possibly together with oxygen. Said method is characterized in that oxygen is introduced into the melting section at high speed in at least one separate second jet and the conditions in which the above-mentioned substances are charged into the first jet and oxygen is charged into a second jet are controlled in such a way as to prevent a flame from being formed. The method enables flexible adaptation to changing operating conditions at guaranteed optimal molten mass quality and environmentally friendly operation.

Title: Hydraulic servo system e.g. for machine oil-cooler temperature control
Inventor: BIANCHETTA DONALD L
IPC: F15B21/0423
Filed: 1996-12-13
Abstract: The hydraulic system (11) is supplied with hydraulic fluid from a sump (12)by a pump. A temperature sensor (36) on the hydraulic line (35) from the sump is connected to a control circuit (37) which controls a shut-off valve (14) to block the hydraulic flow through the oil cooler (13) if the temperature of the hydraulic fluid is below a set level. The return flow is then ducted back to the sump via a non return valve (43). The main flow control valve is spring loaded into the closed position and is opened by a bleed connection (19) from the main hydraulic line (16) generating a pressure build-up to counteract the spring pressure. A solenoid valve (22) vents the bleed flow when the fluid temperature is below the set level, and thereby closes the flow to the oil cooler.

Patent DE-19718388-A1 (DE)
Title: Signal processing unit for trolley bus power collection control
Inventor: LAUNIER FRANCIS
IPC: B60M1/14
Filed: 1997-04-30
Abstract: The processing unit (2) includes an input unit which filters, amplifies and conditions each of several modulated signals. Each signal has an indicator for the request to switch the course run of a power collection system to either a turning transmission line or a straight line transmission line. A frequency detection unit controls if the conditioned, modulated signal is received and belongs to a predetermined frequency band. A validation signal is generated if the conditions are met. A turning signal demodulation unit and a straight ahead line signal demodulation unit receive a conditioned, modulated turning signal and a conditioned, modulated straight line signal, respectively. The demodulation units receive the validation signal and generate a lower, logical signal when the turning or straight ahead line signal and the validation signal are received simultaneously in the respective demodulator. An output unit receives the logical signals of both demodulation units and controls relays in accordance with the reception of the turning or straight line signal.

Patent DE-19736426-A1 (DE)
Title: Motor vehicle suspension control device
Inventor: ICHIMARU NOBUYUKI
IPC: B60G17/015
Filed: 1997-08-21
Abstract: The suspension settings are controlled by hydraulic valves operated by solenoids. Each solenoid is driven in a proportional control by a selected current level. A dithering signal is superimposed on the solenoid current. This causes the valve element to oscillate slightly and thus free it from any sticking characteristics. The valve is easily adjusted in either direction and is thus free from hysteresis effects. The dithering signal is derived by varying the mark-space ratio of a pulse width modulated signal.
