Title: Current control for DC traction - with electronic logic switching circuit for smooth torque value compared to manually set reference
Inventor: BISKUP KONRAD ING GRAD
IPC: B60L15/24
Filed: 1975-10-02
Abstract: The DC traction is controlled by a servo motor which adjusts the motor current in response to a reference value set by the driver's controls. An electronic control provides a smooth torque control. The electronic control generates correction signals for the servo motor to change the motor current in such a way that sudden torque changes are accommodated. The starting current can be greater than the reduction of current for retardation so that a smooth control is possible. The electronic control provides a more precise adjustment of the motor current.

Title: Initiation of carbon monoxide oxidn. - in fluid catalytic cracking regenerators by increase of coke content of regenerated catalyst and then of air flow rate
Inventor: CONNER ALGIE JAMES
IPC: C10G11/18
Filed: 1975-11-07
Abstract: Initiating the oxidn. of CO to CO2 in a dense-phase catalyst bed in the regeneration zone of a fluid catalytic cracking (FCC) unit comprises (a) contacting the spent catalyst with fresh regeneration gas (pref. air) to reduce the coke content to a 1st value (pref. 0.1-0.6 wt.%) and produce a CO-contg. regeneration gas; (b) increasing the coke content of the catalyst to a value 0.1-0.5 wt. % higher than the 1st value (pref. 0.2-0.8 wt. %) and maintaining this coke content until a constant dense-bed temp. is reached; and (c) increasing the flow rate of the fresh regeneration gas to reduce the coke content of the catalyst to a value below the 1st value (pref. 0.01-0.09 wt. %) and to oxidise CO to CO2. Increasing the coke content in step (b) increases the supply of fuel which, when the air flow rate is increased, increases the temp. in the dense phase to a level (677-760 degrees C) at which CO oxidn. is initiated; once initiated, the exothermic oxidn. proceeds spontaneously. This prevents post-combustion in the dilute phase, allows part of the heat of combustion to be recovered, and prevents CO emission into the atmosphere.

Patent DE-2659025-A1 (DE)
Inventor: SCHUSTER WERNER
IPC: B62J6/00
Filed: 1976-12-27
Abstract: The lamp circuit provided with a dynamo (1), a headlight (2) and a rear light is connected to an auxiliary current source (7). If the dynamo voltage drops below a minimum value, one relay contact (r2) is disconnected and one relay contact (r1) is closed. By the discharging of a capacitor (C2) via a line (8), a thyristor (T1) is moved out of its blocking position into its zero position by a pulse, as a result of which current flows from the auxiliary current source (7) to the lamps. This connection is disconnected again when the dynamo voltage is sufficiently large. The connection of the auxiliary current source (7) to the lamps can be disconnected by an Off switch (4) for example a push-button key which automatically goes back into its position of rest. Once the dynamo (1) has reached its minimum voltage value, the auxiliary current source (7) is automatically connected into the circuit when this value is subsequently undershot again. In contrast, when the dynamo (1) is switched on only the auxiliary current source (1) is not loaded. <IMAGE>
