Title: Process and apparatus for measuring height of cutting table
Inventor: LANGKJAER CARSTEN
IPC: A01D41/14
Filed: 1997-01-29
Abstract: A method of measuring the height of the cutting table of an agricultural implement relative to a surface of the ground with crops by means of an acoustic transducer (2). The sound signal emitted by the transducer (2) is formed by a pseudonoise signal covering a predetermined frequency band. The sound signal is compared with the reflected signal, and the signals are mutually delayed until the comparison has reached its optimum. The delay represents then a measurement of the distance to the surface of the ground. In this manner only the signals originating from the reflection from the surface of the ground are measured, as it is utilized that these signals must present substantially the same pattern as the emitted signals. In this manner the picking up of even weak signals has been facilitated, whether these signals are weak or not compared to strong interference signals.

Date Sep. 28, 1995Method and device for manufacturing biaxially oriented tubing from thermoplastic material. The method includes forcing the tube over a mandrel at an orientation temperature of the plastic material, which mandrel includes an expansion part which produces expansion in the circumferential direction of the tube, and downstream of the mandrel the exertion of an axial pulling force on the tube, in the course of which the tube encounters a resistance which counteracts the movement of the tube over the mandrel. The method also includes the exertion of an influence sector-wise in an adjustable manner in the circumferential direction of the tube on the resistance which counteracts the movement of the tube over the mandrel. In an advantageous embodiment, the temperature of the plastic material of the tube is influenced sector-wise in an adjustable manner, viewed in the circumferential direction of the tube. The measures according to the invention lead to better control over the manufacture of biaxially oriented tubing.
