Patent DE-19714417-A1 (DE)
Title: Flow resistance characteristic measuring device
Inventor: SPETHMANN ALEXANDER
IPC: G01P5/02
Filed: 1997-04-08
Abstract: The measuring device uses one or more rotational bodies (1). Each rotational body contains a gas or fluid medium (4) in which a body (7) to be tested is suspended, to evaluate the resulting flow resistance characteristics. The rotation of the medium can be achieved using a rotating container, whose walls are coupled to acceleration of the medium by shear forces. The body or bodies surrounded by the medium are realisably fixed, so that a relative movement between them and the rotating medium is achieved. The movement of the rotating medium and the flow pressure acting on the body due to the rotation of the medium can be measured continuously or at desired times. The rotational body may be a vehicle tyre, which is filled with a given quantity of water, providing a parallel flow stream with the flow pressure acting on the test body detected by a lever (8) acting on a pressure sensor (9).

Inventor: BARTLING WERNER
IPC: B27N1/00
Filed: 1997-04-29
Abstract: In an air separation process for wood fibres which contain particles of impurities, the fibres are added together with a vertical, descending stream of auxiliary gas (13) to a substantially irrotational stream of carrier gas (18) slanted relative to the vertical, descending stream. The particles of impurities are loosened from the fibres and eliminated, whereas the cleaned wood fibres are separated from the streams of auxiliary and carrier gas.

Title: Electronic fuel injection controller for jet aircraft gas turbine engine
Inventor: VEILLEUX JUN
IPC: F02M37/04
Filed: 1997-05-28
Abstract: The controller (100) has a sensor (132) connected with an outlet of a fuel pump to detect the amount of fuel supplied to an engine and to output a signal corresponding to the detected flow. A signal processor in an electronic engine control unit (140) is used to compare the actual fuel flow with a desired fuel flow. Then, a control signal corresponding to the difference between the actual and the desired flow is generated. The generated control signal is given to an electrohydraulic servo valve (156) for adjusting the amount of fuel in a bypass line which is connected between the outlet (28) and the inlet (124) of the fuel pump (104). The amount of fuel in the bypass line is adjusted by varying the amount of opening in an orifice provided in the servo valve.
