Abstract: A heating control system in a roller grill has means for setting a set temperature, at least one temperature sensor mounted in the region of the rollers to measure the temperature of the area surrounding the food being heated on the grill, a temperature display in communication with the temperature sensor that indicates the temperature of the food area, and a control device that monitors the temperature measured in the area of the rollers and food and adjusts the input to heating elements to minimize variation of the measured temperature from the set temperature. Another embodiment of the system includes an offset heating structure in at least one roller to allow a temperature offset between two sides of the roller; and means for adjusting the temperature offset between the two sides of the roller.

Abstract: An adjusting device for a sensor unit mounted on a field machine, or a harvester or tractor, and an associated method for positioning the field machine and sensor unit for locating a working edge of a field. The sensor unit can be mounted on a cutter bar assembly of a field machine via a supporting arm. The sensor unit may be adjusted horizontally or vertically. The sensor produces a signal that is communicated to a steering control unit to guide the field machine along the working edge of the field. The position or alignment of the sensor unit relative to a working edge of the field may be indicated on a two-dimensional display.

Abstract: A heavy load transport vehicle which has the ability of transforming from a flat-bed trailer into a multiple-automobile transporter, having a hydraulic-powered retractable upper deck; hydraulic-powered lift arms that are designed to allow the vehicle to transport wide loads and to be loaded from the side of the lower deck; a stabilizer system which minimizes or eliminates lateral movement of the vehicle during operation on the road; a truss assembly that is designed to synchronize the action of the hydraulic-powered lift arms; and a cable pulley system which assists in the raising of the front end of the upper deck.

Abstract: A device for actuating the clutch of a twine wrap device in a big square baler for harvested crops has a pawl attached to the clutch, a shift lever pivotable into the orbit of the pawl, a control device for the shift lever, and an electric motor which is drive-connected with the control device for the shift lever. The electric motor may be connected via an electric circuit with a device for determining the bale length.

Abstract: A hay making machine including at least two working elements in the form of rotary rakes which are carried by intermediate frames. The intermediate frames are arranged on a support frame and supported on the ground by at least one land wheel. The intermediate frames are pivotally connected for following the contours of the ground as picked-up by the land wheels, and for pivoting about axes which extend in the direction of travel between a working position and a transportation position and vice versa. The intermediate frames also support the transmission members of the drive train, especially shafts and the power train, which are needed for conveying the drive energy to the rotary rakes rotating about vertical axes. Furthermore, the intermediate frames are connected together in the vicinity of the articulated connection between adjacent intermediate frames by coupling consisting of two coupling units that co-operate via meshing elements.
