    Abstract: A grill includes a lower platen assembly having a lower grilling surface and a pivotally attached upper platen assembly having an upper grilling surface. The upper platen assembly includes three motors encased in a shell. A cable attached to each motor suspends the upper grilling surface. The grill is automatically calibrated to ensure that the upper grilling surface is level. Each motor independently and sequentially raises the upper grilling surface from the lower grilling surface. When the upper grilling surface lifts from the lower grilling surface, the current in the motor changes. The settings of each motor at this instant are stored in a control to determine the calibration point when the upper grilling surface is level. The grill also automatically recognizes a food item placed on the lower grilling surface to determine the cooking parameters of the grill.

  • Patent number: 5666878
    Abstract: A system that sterilizes and compacts medical waste. The system includes a vessel which has a door that provides access to an inner chamber. The inner chamber is coupled to a compressor and a source of heating fluid. The vessel also has a jacket that surrounds the inner chamber. The jacket is coupled to the source of heating fluid and a source of cooling fluid. The operation of the system is controlled by a controller. To sterilize and compact medical waste, the door is initially opened and the waste is placed inside the inner chamber. The door is closed to seal the vessel. A vacuum is pulled within the inner chamber to remove any moisture contained therein. Simultaneous with the creation of the vacuum is the introduction of heating fluid to the jacket to heat the vessel. Heating fluid is then introduced to the inner chamber to sterilize the waste. After the waste is sterilized, a vacuum is pulled to remove the heating fluid from the inner chamber. The waste is then compacted by a piston.

  • Patent number: 5649473
    Abstract: A platen cover feed system includes a frame supporting a pair of spools. A belt is connected at each end to the spools and can be fed from one spool to the other or vice versa. The spools can be mounted on supports located at the four top corners of the frame, and the rear supports can be adjusted to various heights. The system may include clamps associated with the spools. The clamps can be tightened or loosened manually in order to either fix the belt in place or feed it forward or backward. Thus, the belt can be fed a varying distance in either direction. The belt is generally made of, or coated with, Teflon or a similar non-sticking material.
