Abstract: Disclosed herein is a system and method for optimally designing automobile door seals. The system comprises data storage, data management and model design. The data storage consists of a plurality of storage units, each of which has data necessary for each condition. The data management consists of a plurality of mode selection units for selecting a mode from the data storage according to the characteristics of a door seal to be developed. The model design designs a complete door seal by imposing a variety of conditions on a model selected from the data management and performing various tests.
Abstract: An improved mechanical stoppering apparatus is provided by the present invention for use with a chamber freeze dryer in which at least two shelves supporting a plurality of receptacles containing material to be freeze dried are adjustably suspended from a fixed plate one above the other for substantially isolating the shelves from the walls of the vacuum chamber of the freeze dryer to provide an even rate of sublimation along the entire surface area of the shelves. A drive means is provided for raising the lower shelf individually until the receptacles it supports contact the bottom of the upper shelf, whereupon both shelves move upwardly in tandem toward the fixed plate, the receptacles on the upper shelf being stoppered against the fixed plate and the receptacles on the lower shelf being stoppered against the bottom of the upper plate.
