Title: Facilitating unstable reaction at high temp.-pressure - by removing side stream for extra heating before return to main stream
Inventor: MUELLER-ANDERSEN RUTH
IPC: C02F1/02
Filed: 1990-01-16
Abstract: In converting unstable high molecular wt. organic cpds. at elevated temp. and pressure the formation of free carbon and/or other reactive cpds. in the feed conduit for the reactor (2) is prevented by extn. of a side-stream from a section where the conversion prods. are already more stable. The side stream (5) receives extra heat in a preheater (4) before return into the main stream to produce the desired final temp. related to mixt. conditions and reqd. temp. Effect of temporarily added heat is insufficient to affect reaction. Any hydrogen formed in the reactor stabilises unstable materials in the reactor. USE - Esp. for catalytic conversion of bio-mass or clarified sludge.

Patent DE-4008460-A1 (DE)
Inventor: BRAEGAS PETER DIPL ING
IPC: G01C21/20
Filed: 1990-03-16
Abstract: A navigation system is connected to a receiver for receiving and evaluating traffic information. The receiver transmits the traffic information to the navigation system, which determines a route from the position to a destination as a function of the load on the sections as indicated by the traffic information. This permits traffic-dependent navigation. The reason for not choosing the usual route is indicated by reading out the corresponding traffic information and displaying it to the driver of the vehicle.
