Abstract: The invention relates to a discontinuous method for producing a polyamide by reacting a mixture containing at least one aminonitrile and possibly monomers suitable for producing polyamides with water. Said method consists of the following steps: (1) reacting the mixture with water at a temperature of between 90 and 400  DEG C and a pressure of between 0.1 and 35 x 10<6> Pa, resulting in a reaction mixture; (2) further reacting the reaction mixture at a temperature of between 150 and 400  DEG C and a pressure which is lower than the pressure in step (1), whereby the temperature and pressure are selected in such a way that a first gaseous phase and a first liquid phase or a first solid phase or a mixture of the first solid and first liquid phase are obtained, and that the first gaseous phase is separated from the first liquid or first solid phase or from the mixture of the first liquid and first solid phase; and (3) mixing the first liquid or first solid phase or the mixture of the first liquid and first solid phase with a gaseous or liquid phase containing water, at a temperature of between 150 and 370  DEG C and a pressure of between 0.1 and 30 x 10<6> Pa, which yields a product mixture. According to the method step (1) is carried out in the presence of a Bronsted acid catalyst, selected from a beta-zeolite, sheet-silicate or solid-bed catalyst, consisting essentially of TiO2 with between 70 and 100 weight percent anatase and between 0 and 30 weight percent rutile, in which up to 40 weight percent of the titanium dioxide can be substituted with tungsten oxide, and steps (2) and (3) can be carried out in the presence of said catalyst.

Patent DE-19823284-A1 (DE)
Title: Control system for motor vehicle clutch
Inventor: AMENDT OLIVER DR
IPC: F16H63/46
Filed: 1998-05-25
Abstract: The control system is used for a motor vehicle with a drive unit e.g. motor or IC engine (2), a clutch (3) and a gearbox (4). An operating unit, such as an actuator (13b) for operating engagement and disengagement of the clutch, is controlled by a control unit (13) with an electronic control unit (13a). Sensors (19a,19b) detect the selected gear position in the gearbox.  With first gear or reverse gear applied in the gearbox, and with a running engine and unoperated accelerator and brake pedals, the torque transmitted by the clutch is increased, such that the vehicle creeps. Applying a higher gear, with the engine running and an unoperated accelerator and brake pedals, with speeds higher than a specified limit speed, the clutch transmits torque so that the vehicle creeps further. With speeds lower than the limit speed, the torque transmitted by the clutch is lowered, and no creeping of the vehicle from standstill results.

Title: Robust sensor circuit controlling pumping current to oxygen sensor cell with solid electrolyte, uses combination of analog and digital circuitry, controlling errors when measuring exhaust gas nitrogen oxide and oxygen
Inventor: AMTMANN MARKUS
IPC: G01N27/406
Filed: 1998-08-10
Abstract: A microcontroller (20) determines the actual value (Ip-ist) of the pumping current to the pump cell (27) under control. An actual value of the Nernst voltage (VN-ist) at the cell (34) is determined from this, and a pulse width modulated (PWM) signal is produced. An analog circuit (21) transforms the PWM signal into a pumping current for the pump cell (27). A desired value of the Nernst voltage (VN-soll) is read from a memory (40) for constants. Preferred Features: The memory for constants is programmable and integrated in the microcontroller. A measurement resistance (25) connected before the pump cell drops voltage indicative of the actual value of pumping current (Ip-ist). The microcontroller includes a third subtracter (39), forming the voltage ( DELTA VN) from actual and desired Nernst voltages. A controller (41) produces the pumping current desired value (Ip-soll). A fourth subtracter forms the pumping current difference ( DELTA Ip) in a similar manner. The PWM unit produces the signal and a second controller (43) controls pumping current difference ( DELTA Ip) from the results. Use of ADCs to determine the actual value of pumping current and the actual value of Nernst voltage is described. The analog circuit includes a filter circuit (23) converting the PWM signal to an analog signal. An impedance transformer (24) matches microcontroller output to the required value of current output. The circuit is included in the casing of the sensor plug.
