Title: Process for making a spun-filament fleece from endless synthetic resin filament
Inventor: REIFENHAEUSER HANS
IPC: D04H3/16
Filed: 1987-11-09
Granted: 1991-07-16
Abstract: ABSTRACT OF THE DISCLOSURE      The process for making the spun-filament fleece proceeds in a filament-spinning device having a spinning nozzle system, a cooling shaft, a stretching gap, a diffuser shaft, a continuously moving mat-receiving conveyor and a device for feeding process air and for drawing or removing outflowing air through the mat-receiving conveyor.  The cooling shaft has a shaft wall provided with a plurality of air orifices. That allows process air required for cooling to be fed into the cooling shaft. That air flow at least partially is drawn through the mat-receiving conveyor and the spun-filament fleece is formed by the deposited filament loops.  The deposited length of the endless filament loops is measured over the spun-filament fleece width in the finished fleece.  The measured value is compared with a predetermined set value.  On deviation of the measured value from the set value the setting angles of pivoting wings which are each pivotable about a horizontal axis and which are located at the outlet of the diffuser shaft are changed. On a positive deviation of the measured value of the thickness from the set value the setting angle is decreased (deposited length larger than the set value).

Title: Front and rear wheel steering vehicle with a minimized maneuvering area
Inventor: FURUKAWA YOSHIMI
IPC: B62D6/00
Filed: 1988-09-15
Granted: 1991-09-17
Abstract: ABSTRACT OF THE DISCLOSURE      The maneuvering area of a front and rear wheel steering vehicle is minimized by making the rear wheels follow the trajectories of the front wheels.  This can be accomplished by steering the rear wheels so that they may coincide, in a spatially fixed absolute coordinate system, with the steer angles of the front wheels when they were located at the same locations as the current positions of the rear wheels.  Further proposed is an algorithm for achieving the required rear wheel steering control which comprises the steps of detecting the yaw angle of the vehicle body and subtracting from the steer angles of the front wheels at the time point when the front wheels were located at the current positions of the rear wheels, the change in the yaw angle of the vehicle body from the said time point to the current time point.  Thus, the vehicle is able to go through a most narrow and tortuous road for the given size of the vehicle without deviating from the prescribed course of the road, and the driver is required only to get the front part of the vehicle pass through narrow points of the road without paying attention to the rear part of the vehicle.
