Abstract: Conduit bore plugging for rapid selective plugging of a fluid path within a conduit has a driver handle having a motive chamber with a driving chamber, the motive chamber attached to the driver handle, wherein the motive chamber defines a passage. A shaft-like plugging device has a bar connected to a rod, wherein the bar is driven in a first direction by the driver handle via the driving chamber, and guided and supported by the motive via the passage. A fluid path in a conduit is selectively plugged with an expandable seal via expanding the expandable seal within the bore of the conduit by sliding a sleeve over a rod of the bar into a flange contiguous with an end of the expandable seal, and by engaging the sleeve at one end by interference with an abutment surface as the bar is driven via the driving chamber.

Abstract: An herb vaporizing apparatus includes an herb receiving port, a grinder to grind the herb, and a heating chamber for heating the ground herb to create a vapor. A first end of the heating chamber is positioned closer to a top of the apparatus than a second end of the heating chamber, such that the ground herb generally moves in at least a partially downward direction as it travels through the heating chamber. The apparatus further includes a screw feeder positioned within the heating chamber that rotates and moves the ground herb within the heating chamber. The apparatus further includes an air pump for pumping vapor out of the heating chamber and a valve positioned along an airway between the heating chamber and a vapor output. The valve permits air and the vapor to move from the heating chamber to the vapor output only while the air pump is activated.
