  • Patent number: 5170288
    Abstract: An arrangement is provided for removing foreign substances from a mirror. A vibrator for vibrating the mirror includes a vibration controlling unit for supplying power to the vibrator. As the vibration controlling unit is located close to the vibrator, the length of the conductive wire which transmits the power can be minimized so as to reduce radio noise. The heat generated by the vibration control unit can be radiated sufficiently through a metallic case member and the vibration controlling unit can be disposed in the closed, small space between the mirror and the housing. Therefore, the size of the housing can be reduced so as to minimize the space which surrounds the vibration control unit. Further, the vibration control unit can be protected from contamination due to the closed case member.

  • Patent number: 5097755
    Abstract: A method and apparatus are disclosed for processing produce and particularly fresh vegetables for salads. The vegetables are stored in an area near the beginning of the process line, and the storage area is partitioned by vinyl strips to create a temperature gradient for different vegetables. The vegetables are first cleaned on mesh conveyors under high pressure nozzles that spray chlorinated water at the desired storage temperature of the vegetables. A trimming table includes a lower conveyor for moving the vegetables for hand processing. An upper, cleated conveyor carries the vegetables to a slicer. Another cleated conveyor lifts the sliced vegetables vertically into a hopper where they are mixed with cooling water that then flows through a significant horizontal length of pipe. The vegetables move to shaker tables that provide the bulk of the dewatering and then vibrate the vegetables into a single layer for air drying.

  • Patent number: 4979315
    Abstract: Subsequent to formation of a filter cake upon the surface of belt and further vacuum filtration (via vacuum trays), the cake passed below and is covered by an impervious sheet, and is dried by application of radiation, e.g. microwaves, radio waves, through the sheet, along with further evacuation (via vacuum trays) below the sheet. Because the cake is under suction pressure, the evaporation temperature of the filtrate is lowered to a level which will not adversely affect the cake, and which can be reached very rapidly by application of this form of radiation.
