Abstract: A mechanical cabinet for storing and delivering inventory, wherein carrier units having inserts are selectively delivered to a delivery station by a conveyor mechanism which includes a vertical conveyor having an endless chain and sprocket wheels. The inventory items are contained within inserts in the carrier units, and when a carrier unit is located at the delivery station, an ejection device arranged on a side of the carrier unit opposite the delivery station operates to eject the inserts in order to make the inventory items available. The ejection device is provided with a drive which is switched to alternate with a drive which is provided for the carrier units.

Abstract: In a drum type chopper, a drum, rotatable about a stationary axis, mounts cutters which co-act with a counter knife in effecting a chopping action. A cylindrical grinding wheel is positioned to sharpen the cutters on the drum. The grinding wheel is movable between a rest position and a grinding position relative to the cutters. The grinding wheel has an axial length corresponding approximately to the axial length of the drum. Further, during the grinding operation, the grinding wheel is rotated and reciprocated relative to the same axis.

Abstract: In a chopper, at least one cutter rotates about an axis moving over a retaining wall of a chopper housing and past an opposing knife edge located at the inlet opening into the chopper. The opposing knife edge is adjustably supported on a support relative to the plane or circle of revolution of the cutter. An adjustment device actuatable at a location exterior of the chopper housing effects the adjustment of the opposing knife edge when a locking device is released. The locking device includes a clamping device for pressing the opposite ends of the opposing cutting edge against the support. A force accumulator provides an elastic force for maintaining the clamping action. The locking device also includes a releasing device acting against the force accumulator for releasing the clamping action.

Abstract: In a field chopper or chopper forage harvester, a disc wheel chopper is mounted within a housing for rotation about an axis with an elongated discharge tube opening from the radially outer surface of the housing. A crushing device is located within the discharge tube and is positioned to receive the material carried along the circumferentially inner surface of the housing by the disc wheel. The discharge tube forms an air transport duct located radially inwardly of the crushing device relative to the axis of the disc wheel chopper so that air flow generated by the disc wheel bypasses the crushing device and flows through the air transport duct for supporting the flow of material exiting from the crushing device.

Abstract: A forage or picking harvester for the rough grinding of grain has a housing with a cylindrically shaped outer wall. A cutting blade wheel is located within the housing coaxial with the cylindrically shaped wall. The housing has an inlet and an outlet with a discharge duct forming the outlet and extending outwardly from the cylindrically shaped wall. Blades are mounted on the cutting blade wheel and extend radially of the axis of the wheel with the radially outer ends moving along a circle located at the inside surface of the cylindrically shaped wall. A comb-like arrangement of bearing arms is located within the discharge duct adjacent to the opening from the housing so that the blades on the cutting wheel hurl the grains against the bearing arms whereby the arms effect a rough grinding of the grain.

Abstract: A forage or picking harvester unit includes a cylindrical cutter followed by an impeller fan with a crushing device in the path between the cutter and the fan. In the cylindrical cutter, the cutting wheel shaft is arranged perpendicularly relative to the shaft of the impeller fan. The crushing device is formed of crushing rollers with the roller axes extending parallel to the cutting wheel shaft. The crushing rollers are positioned in the path of the material flowing from the cylindrical cutter into the impeller fan. The circumferential surfaces of the crushing rollers are fluted in the direction parallel to the roller axes. The fluted surfaces form alternating teeth and recesses so that the circumferential surfaces of the crushing rollers can intermesh.

Abstract: In a forage cutter, a cutting wheel is rotatably mounted within a housing. For an angular portion of the wheel relative to the housing, its outer circumferential periphery is positioned adjacent to a backing wall of the housing. Alternating knives and blades are attached to the cutting wheel about its circumferential periphery with the knives coacting with a stationary cutting plate to cut forage material introduced into the housing. After the material is cut it is carried downwardly to a space where it is crushed and the crushed material is moved upwardly by the blades on the cutting wheel to an outlet passageway. The crushing space is provided by diverging the backing wall outwardly from the outer circumferential periphery of the cutting wheel. Following the crushing space, the backing wall converges inwardly toward the outer circumferential periphery of the cutting wheel. The outlet passageway follows the inwardly converging backing wall in the direction of rotation of the cutting wheel.

Abstract: To achieve a greater accuracy, an optoelectronic measuring method and an apparatus for measuring with optoelectronic instruments provides that one or two light rays of one or two light transmitters, such as lasers, are directed at an acute angle onto a surface to be shaped and that the distance covered from the starting position to the end position in the shaping operations is measured by means of a photodetector, e.g., a diode camera, which is set up perpendicular to the light spot or spots.

Abstract: A multi row corn cutter harvester is disclosed having two positions of operation when connected to a three point towing bracket of a tractor. The harvester may be connected either alongside the tractor in an operating mode or behind the tractor in a second operating mode. A system of drive including relative locations of input and output shafts and connections is disclosed.
