Title: Variable ratio planetary gearing unit for track-laying vehicles
Inventor: TENBERGE PETER DR
IPC: F16H47/04
Filed: 1988-10-05
Abstract: In a variable ratio planetary gearing unit (3) for track-laying vehicles, with which the steering power required for cornering is superimposed on driving mode by means of summing differentials and which has a hydrostatic-mechanical torque division which is summed in a summing gearing unit (31), it is intended to keep the power losses of the hydrostatic branch which operates with poor efficiency as small as possible and at the same time to make infinitely variable steering possible over all radius ranges. For this purpose, the summing gearing unit (31) can be shifted in two stages covering at least two radius ranges, an adaptation of rpm to the gearing elements taking place at the shift points for a infinitely variable transition in each case. <IMAGE>

Title: Bale breaker - has sensor to give contents hardness and height to position breaker for max effectiveness
Inventor: STAEHELI CHRISTOPH
IPC: D01G7/10
Filed: 1989-08-10
Abstract: The sensor to determine the hardness of the fibre bale, in a bale breaking operation, pref. an optical, acoustic or radar wave sensor, delivers a signal which represents the bale hardness. This signal is used to control the positioning and working depth of the bale breaker. Pref. the hardness signal is developed from the fluctuations, and especially the amplitude fluctuations in the sensor signal, by adding the positive deviations of the sensor signal from a mean signal value. The sensor signal is scanned pref. with a frequency greater than twice the basic signal frequency. A sensor is used such as to be started periodically and passes the actual measured values directly to the computer in digital form to be stored. The hardness is sepd. for each bale, such as each unit in a row of bales. ADVANTAGE - The assessment of the bale hardness, together with the height of the fibre material within the bale, are established at the same time for the max. effective use of the bale breaking components.
