Abstract: An apparatus for dispensing particulate agglomerating solids in accordance with the invention includes a container for holding the particulate solids to be dispensed having a foraminous discharge disposed at the bottom of the container; apparatus for applying agitation to the particulate solids within the container to break up agglomerations to cause the solid to be free flowing through the foraminous discharge; a transporting mechanism disposed beneath the discharge with a top surface along which the solids flow from a receiving area upon which the solids fall upon the application of agitation to the solids to a discharge area having an end from which the solids are discharged, the top surface being substantially flat at the receiving area and being sloped downward from the receiving area to the discharge area; apparatus for applying vibrations to the transporting mechanism for causing the solids to flow from the receiving area to the discharge area; and a controller for causing the activation of the apparat

Abstract: An apparatus for making dilutions of a sample with a diluent to a predetermined dilution factor f by weight of the diluent is disclosed. A scale with TARE capability produces an output signal of the weight W of a sample within a container less the weight of the container. A dilution factor control is provided for setting the predetermined dilution factor f. Apparatus is provided for calculating and storing the value TW=W/f which is the total weight of the sample plus the weight of the diluent which is required to dilute the sample to the predetermined dilution factor f. A pump is connected between a reservoir of diluent and the container for the sample for pumping the amount of diluent into the container which is required to dilute the sample to the predetermined weight dilution factor f. The scale provides a continuous output of the weight W of the sample plus diluent in the container at any instant in time. Apparatus is provided for calculating when TW-W=0.
