Patent DE-3363791-D1 (DE)
Title: Resilient torsional coupling
Inventor: WOLF FRANZ JOSEF
IPC: F16D3/62
Filed: 1983-10-07
Granted: 1986-07-03
Abstract: The invention relates to a torsionally elastic coupling in which the two coupling halves are connected to one another via at least one movement-converting intermediate member and at least one spring member, which allow the two coupling halves to rotate relative to one another. To improve the service life of a torsionally elastic coupling of this type by reducing shear stress and making it possible to subject the resilient intermediate members to pressure, coupling members are inserted between the movement-converting intermediate members and the resilient intermediate members.

Title: Working depth control system for vehicle with ground working implement
Inventor: WIEGARDT GORDON K
IPC: A01B63/111
Filed: 1983-03-21
Granted: 1989-02-16
Abstract: A tractor (10) includes a hitch (26) for pulling a ground-working implement. A hydraulic cylinder (34) is extensible and retractable to lower and raise the implement. A control system (50) senses operating parameters, including wheel slip, engine speed, draft force and implement or rockshaft position. Error signals are derived from the sensed wheel slip, engine speed and draft force and correspond set point signals. The error signals are combined into a composite or combined error signal. The larger of (a) the combined error signal and (b) a separately determined position error signal, is selected and converted to a pulsewidth modulated valve control signal which is applied to a control valve (42) which then actuates the cylinder to move the implement to reduce the magnitude of the selected error signal. Certain set point signals are derived from the corresponding parameter signals themselves.

Abstract: Reproduced signals from two heads (1,11) are amplified (2,12) for application to demodulators (3,13) and dropout detectors (6,16). The demodulated signals are digitised (4,14) into 8-bit data streams which are checked (5,15) for the presence of a predetermined bit sequence. The dropout detectors (6,16) verify, e.g. the envelope of an FM signal and produce an output signifying whether or not dropout has occurred. This output is delayed (7,17) before application to a switching circuit (9,19) and in the presence of dropout the switching is set (8) to forward the reserved bit combination to a time-transforming, error-correcting and multiplexing circuit (20). The corrected indication is used to control a dropout store (24) connected between further switching circuits (23,21).
