| A method for controlling a power-split gear shift device in a vehicle by providing an electric variator and a transmission with variable gear shift and connecting a drive motor to a traction drive of the vehicle. The electric variator has a compound gear train with at least one first and at least one second electric machine. The method also includes providing a controller for the electric machines for steplessly varying a gear shift of the compound gear train. Upon detection of an external power requirement by an electric consumer, a gear shift region of the transmission with variable gear shift is set to operate the first electric machine in a generator mode and to operate the second electric machine to compensate for an existing power deficit or a power excess relative to an external power demand. | ||||||

| A method for controlling a seeding apparatus including sensing a ground force acting on a furrow opener of the seeding apparatus and providing a ground force sensor signal in dependence upon the ground force acting on the furrow opener. The method further includes providing an actuator to apply a bias force to a packer wheel of the seeding apparatus. The method also includes providing a control device operative to receive the ground force sensor signal and an input from an operator and to adjust the bias force that the actuator applies to the packer wheel in dependence on at least one of the ground force sensor signal and the input from the operator. | ||||||

| A diagonal brace apparatus for an implement frame includes a bias element connected to a front location on a front portion of the implement frame and connected to a rear location on a rear portion of the implement frame laterally offset from the front location. The bias element is operative to exert a bias force resisting rearward movement of an outer end of the implement frame with respect to an inner end of the implement frame. Conveniently the bias element is provided by a hydraulic cylinder which exerts a bias force and can extend to allow the frame to flex to reduce shock loading on the implement when excessive forces are exerted on the frame. | ||||||

| A seeding apparatus adapted for being drawn across the ground of an agricultural field by a tractor, comprising at least one frame adapted for engagement with the tractor, at least one seeding unit comprising, a first trailing arm having a proximal end and a distal end, means for securely engaging the proximal end of the first trailing arm with the frame, a furrow opener, means for securely engaging the furrow opener with the first trailing arm proximate the distal end of the first trailing arm, means for sensing the amount of ground force to which the furrow opener is being subjected, means for placing seed in the opened furrow, a second trailing arm having a proximal end and a distal end, means for securely and pivotally engaging the proximal end of the second trailing arm with the frame, a packing wheel in secure engagement with the second trailing arm proximate the distal end of the second trailing arm and adapted to pack the seeded furrow, means for variably biasing the packing wheel toward the ground in communication with the means for sensing the amount of ground force to which the furrow opener is being subjected and means for engaging the at least one seeding unit with the at least one frame wherein information relating to the amount of ground force to which the furrow opener is being subjected is supplied by the sensor to the means for variably biasing the packing wheel toward the ground to control the amount of bias applied to the packing wheel. | ||||||
| 34 | Load sensing gearbox | US365816 | 1989-06-14 | US4979603A | 1990-12-25 | Graham Wheatland |
| A universal load sensing gearbox integrating a safety mechanism for use, for instance, with motor driven closures, such as garage doors, barriers and gates, includes a housing which encases a worm slidably mounted on an input shaft and adapted for rotation therewith. The input shaft is connected with the motor driving the closure. The worm is engaged with a worm gear which is mounted on an output shaft which is connected with the closure. Dished washers are provided generally around the input shaft at both ends of the worm to urge the worm in a central meshed engagement with the worm gear. A motion transmission device is provided on the worm and is adapted to slide therewith to detect a longitudinal movement thereof and to transmit this movement to an actuating device which is adapted to stop and/or reverse the motor. Therefore, sufficient resistance to the rotation of the output shaft resulting, for example, from the closure encountering an object pressure, causes the worm to be displaced along the input shaft against the dished washers along with the transmission device. A sufficient movement of the transmission device causes the actuating device to trip a limit switch which triggers the stoppage and/or reversing of the motor. The load sensing gearbox is also intended for agricultural applications using reducing gearboxes, for actuating aircraft wing flaps, for conveyer belts, etc. | ||||||
| 35 | Monitoring device for machine parts | US221032 | 1980-12-29 | US4415888A | 1983-11-15 | Cornelis van der Lely |
| A machine has two relatively movable portions and relative movement between the portions is sensed by means generating an electric current. In the preferred embodiment this means comprises a permanent magnet on one portion and an induction coil and a soft-iron core on the other portion. The two portions are parts of an overload coupling interconnected with a shear pin. When the coupling is overloaded, a shear pin fractures and the two portions rotate relative to one another. This causes a current to be generated in the coil which actuates a signal element. The device provides a visual indication of the operative condition of the two portions. | ||||||
| 36 | Agricultural implement | US164968 | 1980-07-01 | US4304087A | 1981-12-08 | Petrus W. Zweegers |
| An agricultural implement has a first frame portion for coupling to a tractor and a second frame portion has one end pivotally connected to the first frame portion. The pivotal connection is such that the second frame portion will pivot with respect to the first frame portion only when a force exerted on the second frame portion exceeds a pre-determined magnitude. A carrier, upon which are mounted working tools, is pivotally connected to the other end of the second frame portion and there is a spring device between the carrier and the second frame portion. This spring device exerts such a force that the outer end portion of the carrier can only pivot in the direction of normal operation of the implement. | ||||||
| 37 | Semi-mounted plow | US13882771 | 1971-04-29 | US3783950A | 1974-01-08 | GEURTS C |
| A semi-mounted moldboard plow connected to the draft links of a tractor by a hitch having longitudinal, upright and transverse pivotal movements with respect to the frame of the plow. The hitch is connected to a tail wheel of the plow so that the wheel turns in the direction of movement of the tractor. Each plow bottom of the plow is held in the ground working position by a hydraulic holding, release and return mechanism. Fluidly coupled with the hydraulic mechanism of each plow bottom is a fluid cylinder which yieldably holds a colter in ground working position.
