  • Patent number: 7472810
    Abstract: A dosing dispenser for dispensing predetermined quantities of a flowable material, particularly baby formula, includes a dosing device having a dosing compartment located to align its upper end with a receptacle for the flowable material, when the dosing device is in a rear limit position, for filling with the flowable material, and to align its lower end with a dispensing outlet when the dispensing device is in a forward limit position for dispensing the flowable material in the dosing compartment from the housing. The dispenser further includes a restraining device for restraining movement of the dosing device, when starting a movement in one direction, against movement in the opposite direction until the dosing device has completed its movement in the one direction, to thereby prevent dispensing of less than the predetermined quantity of the flowable material by only a partial filling of the dosing compartment.

  • Patent number: 4221307
    Abstract: A knife gate for use in pneumatic conveying equipment is the subject of the present invention. The improved knife gate device is constructed utilizing first and second guide plates disposed in spaced apart relationship with a resilient member positioned behind each of the plates. Each plate is characterized by an opening and a planar surface extending on either side of the opening. A reciprocating gate means is disposed between the plates and places the yieldable means under compression. The gate means has an opening and a planar surface extending on at least one side of the opening. The gate means is moveable between an open position wherein all of the openings are aligned and a closed position wherein the planar surface of the gate means moves past the openings in the guide plates to close the latter.
