摘要： A fume hood includes a polygonal-shaped work top providing three or more equally-spaced work areas. A tubular column with a lower apertured portion is located at the center of the work top for exhausting heavier-than-air gases. A plenum located above the work top and supported by the tubular column is provided with slots located above the work openings for collecting and exhausting lighter-than-air gases. Transparent viewing screens permit inspection of all work locations from a single vantage point. A central pedestal is used to support the hood and to route plumbing and electrical conduits from the floor. The system is easily convertible between up-draft and down-draft exhaust without the need for special baffles.

摘要： A multi-level table for student activity use, such as in science or art labs, includes a top which may be adjusted relative to a base in either a raised or a lowered position. In either position, the table top is rigidly secured to the base for stability and the adjustment between positions is accomplished without removing the top from the base. Folding seats may be folded into a very tin profile for storage beneath the table top when not in use. A novel upright support is also disclosed which may be removably mounted onto the table top for use in supporting equipment used in laboratory work.
