  • Device maximizing dispersion of aggregate in liquid diluent
    Patent number: 5700087
    Abstract: For specialized use to secure reliable standardized complete distribution or solution of aggregate mixed into a liquid diluent, a vessel having an interior hemispherical concave bottom having extending upwardly centrally from the concave bottom an arcuate conical member having upright concavely-shaped circumscribing sides. The vessel is taken in conjunction with a stably mounted mixing structure having a downwardly-extending shaft and mixing blades thereof. The shaft on a lower portion thereof supports balanced mixing blades extending radially outwardly from the mixing shaft. The mixing blades are positioned to be substantially spaced below a predetermined liquid level of liquid diluent containing a dissolvable or suspendable aggregate and to be substantially spaced above an upper end of the centrally upwardly arcuate conical member.

  • Solute dissolution reciprocating flow-cell
    Patent number: 5540496
    Abstract: A combination of a flow-cell with a rate of flow controllable and set to obtain and maintain a solvent or diluent predetermined low flow pressure from the flow-cell's inlet to the flow-cell's outlet, in which at-least an outlet thereof is alternately raised to a height above the inlet thereof sufficiently relative to mass of individual solute(s) and/or individual bead(s) (or other insoluble mass(es)) as to permit the mass of the individual solute(s) and/or individual bead(s) to move by gravity from a direction of the outlet end toward the inlet end of the flow-cell as part of a mechanism ascertainable of improved dissolving of solute and/or suspension of particles of insoluble matter.

  • Dissolution testing machine
    Patent number: 5011662
    Abstract: A dissolution testing machine has a container for a liquid and a holder for pellets, a support for supporting the holder within the container and a drive enabling the holder to be reciprocated via its support so that solvent flushes into and out of the holder.The holder may be a mesh tube, or a solid walled tube, closed at both ends by an apertured member. A set of containers may receive the holder successively, each container containing a solvent of the same or different characteristics.
