Title: Automatic vehicle speed control arrangement
Inventor: HIGASHIMATA AKIRA
IPC: B60W50/14
Filed: 1999-05-27
Abstract: The arrangement includes a distance detector (1), a vehicle speed detector (2), a vehicle distance control (5), and a vehicle speed servo-control which distributes a calculated vehicle power on a vehicle drive system and a vehicle brake system.

A vehicle speed servo-control calculates a vehicle power necessary to reach the target value of the vehicle speed, and distributes the calculated vehicle power on a drive force for a vehicle drive system and a brake force for a vehicle brake system.  A compressor compares the detected value of the vehicle speed with an adjusted lower limit of the vehicle speed within a vehicle speed control range. A control release instruction generator outputs a release instruction in response to the comparison to initiate a calculation of the vehicle speed target value and the vehicle power. A function generator reacts to the result of the comparison, and produces and outputs a predetermined function to the vehicle brake system to continue a control of the brake force exclusively through the vehicle brake system. An Independent claim is provided for a corresponding vehicle speed control method.

Title: Procedure for quick balancing of air flows in complex paint spraying booth entails adjustment of exhaust gas vent fan speed and venturi gap width through co-relation of data of disturbed exhaust gas flow with desired exhaust flow speed
Inventor: FILEV DIMITAR
IPC: B05B15/12
Filed: 1999-09-17
Abstract: The procedure involves adjustment of an exhaust gas vent fan(33) speed and venturi gap(49) width through co-relation of the data of a disturbed exhaust gas flow with a desired exhaust flow speed during a desired exhaust gas pressure drop in order to maintain a target vent fan speed as a function of the pressure drop and the exhaust flow speed. The adjustment for the exhaust vent fan speed and venturi gap width is derived from this curve.  The procedure also involves adjustment of a feed vent fan speed in positions for each cross flow damper through the resolution of an objective optimizing function for the sum of the cross flows through the use of disturbed feed vent fan speed and cross flow speed values, which establishes optimum cross flow speeds during a specific common air feed speed from which the feed vent fan and cross flow damper positions can be derived.
