1. A gravimetric blender comprising:
- a) a vertically oriented conduit;
b) a vacuum pump, supported by the conduit, and having a suction inlet communicating with the conduit interior;
c) a plurality of receivers, each connected to the conduit, being vertically supported thereby and being angularly spaced thereabout, for vacuum draw though the individual receivers via the conduit by the pump, each receiver having a resin material/vacuum drawn stream inlet and a resin outlet;
d) each receiver having only a single tube therewithin extending from the resin material/vacuum drawn stream inlet to the connection of the receiver with the conduit, each tube comprising;
i) an air cylinder within and connected to the tube, positioned to close the receiver connection to the conduit upon actuation thereof;
ii) a plug within the tube and connected thereto for downwardly deflecting resin material carried by a resin material/vacuum drawn stream entering the receiver via the tube;
iii) a valve at the resin outlet, closing responsively to vacuum drawn within the receiver and opening responsively to the presence of resin material within the receiver in the absence of vacuum draw within the respective receiver; and
iv) a plate connected to the air cylinder, for closing the receiver-conduit connection upon air cylinder actuation.

3. A gravimetric blender comprising:
-
a) a vertical conduit; b) a vacuum pump having a suction inlet communicating with the interior of the conduit; c) a plurality of receivers connected to the conduit , each receiver being vertically supported thereby for vacuum draw though the receiver connection and the receiver via the conduit by the pump, each receiver having a resin material/vacuum drawn stream inlet and a resin outlet; d) each receiver having only a single tube therewithin extending through the receiver from the resin material/vacuum drawn stream inlet to the connection of the receiver with the conduit;
the tube further comprising;i) an air cylinder within the tube; ii) a plate connected to the air cylinder at a first end thereof and positioned to close the connection to the vertical conduit upon actuation of the air cylinder; and iii) a plug connected to a second end of the air cylinder for opening the inlet upon actuation of the air cylinder and downwardly deflecting any incoming resin material vacuum drawn stream. - View Dependent Claims (6, 7, 8, 9, 10)

4. A gravimetric blender comprising:
-
a) a vertical conduit; b) a vacuum pump, supported by the conduit, having a suction inlet communicating with the interior of the conduit; c) a plurality of receivers connected to the conduit and vertically supported thereby, for vacuum draw though the receiver connection and the receiver via the conduit by the pump, each receiver having a resin material/vacuum drawn stream inlet and a resin outlet, the receivers being angularly spaced about the conduit; d) each receiver having a tube therewithin extending from the resin material/vacuum drawn stream inlet to the connection of the receiver with the conduit;
the tube further comprising;i) an air cylinder within the tube; and ii) a plate connected to the air cylinder and positioned to close the connection to the vertical conduit upon actuation of the air cylinder.
