  • Patent number: 7008032
    Abstract: A refrigerator includes French-style doors and a rotating mullion. The rotating mullion is mounted to one of the French-style doors through first and second hinge members. Each of the first and second hinge members include first and second hinge elements having corresponding cam members. The cam members include multiple lobes and extend about hinge pins that define an axis of rotation for the mullion. The multiple lobes actually define first and second detent positions for the rotating mullion. A spring biases the first cam member against the second cam member so that the rotating mullion is positively maintained in either the first or second position. The mullion is formed from mating halves, each including a portion of an integrally formed pin element. The pin element travels within a guide element to automatically rotate the mullion between the first and second positions during use.

  • Publication number: 20050204715
    Abstract: As crop materials are severed from the field, they pass through two successive pairs of counter-rotating conditioning rolls before being returned to the ground. The front rolls are preferably ribbed, metal rolls wherein the ribs of one roll are intermeshed with those of the other roll so as to crimp the stems of the crop materials as they pass between the rolls. The hard metal ribs also aggressively feed the materials rearwardly into the second set of rolls, which are preferably compressive surface rolls made of rubber or the like and provided with wide, intermeshed bars about their periphery. The tension mechanism for the rolls includes single-acting hydraulic cylinders that squeeze the rolls together to the extent permitted by adjustable stop structure used to set gaps between the rolls. In typical operations, the gap between the rear rolls is set to be considerably smaller than the gap between the front rolls.

  • Patent number: 6047532
    Abstract: A crop harvesting header includes a wide cutter for severing crop across a relatively large cutting width, and framework defining a discharge opening spaced rearwardly from the cutter. The discharge opening has a width that is less than the cutting width such that crop severed laterally outboard of the discharge opening by the cutter must be conveyed inwardly before passing through the opening. At least one laterally extending, rotatable auger is located between the cutter and discharge opening for converging severed crop centrally from the areas located laterally outboard of the discharge opening and to project the crop through the opening when rotated. The header includes an auger support for rotatably supporting the auger between its opposite ends on the header framework so that the auger is capable of spanning the long distance corresponding to the large cutting width defined by the sickle bar.

  • Patent number: 5906089
    Abstract: The windrower or other harvester has a hydraulic lift circuit for its header that includes a pair of double-acting cylinders which operate in concert to raise the header and provide a solid, lower limit for downward swinging of the header. The two cylinders are connected to one another in a master-slave relationship, and the slave cylinder has its return line normally blocked by a one-way check valve so that a body of fluid is trapped against the piston of the slave cylinder during field operations. This stabilizes the two cylinders to reduce header bounce.

  • Patent number: 5876387
    Abstract: The subject of the invention is a suction draw off device which permits a drawing off by suction of secretion, blood or the like and a closure of a wound by means of vacuum. Thereby, the suction draw off device has a container (1) closable by means of a lid (2), a bag (3) with a tube (4) which can be placed in the container (1), a passage for the tube in the upper part of the container wall or in the lid for drawing of the secretion or the like into the bag (3) and an opening in the container wall or in the lid for generating a vacuum in the container (3). Thereby, the suction draw off device is so configured that it is closed in a vacuum-tight manner in the closed condition of the container (1), so that the secretion suction draw off device is operable independently of a vacuum pump unit after a vacuum has once been generated in the container (1).
