Abstract: A mobile workstation capable of supporting various types of electrical or diagnostic equipment for use primarily in the health care environment comprising a work surface supported by a pedestal and a base. The base includes casters for easy portability of the workstation. The workstation further includes a height adjustment mechanism and a counterbalance. The counterbalance may be supported from the underside of the top of the work surface of the workstation for counterbalancing the weight of the equipment that may be carried on the work surface so as to provide versatility when adjusting the height of the workstation from a seated position to a standing position with minimal effort from the user.

Abstract: A duct and flop-gate construction for handling particulate material and a method of handling dust or other particulate material. The collected material drops down a duct which contains a flop-gate for directing the material to either of two bins. A mild current of air is drawn upwardly through the duct and flop-gate counter to the movement of the material to subject the bins to negative pressure and prevent outward leakage. The same duct serves both to carry material downwardly to the bins and as a means for applying negative pressure to the bins.
