Abstract: A filler product supply system (5) and method using two or more conduits (120, 130) to deliver filler product under pressure from product reservoirs (200, 210) to in fluid isolation to a supply manifold (58). Filler product is further delivered in fluid isolation from supply manifold (58) through conduits (170, 171) to two or more filling heads (180, 190). Downstream from filling heads (180, 190), the previously isolated fluid lines are combined to introduce two or more distinct filler products into a single container without creating a homogenous mixture.

Abstract: A fastener includes a threaded shaft and a grippable head secured to the threaded shaft. An aperture extends through the shaft toward the head. The aperture extends partially through the head. In some embodiments, the shaft includes both threaded and unthreaded portions. In such embodiments, the aperture may extend slightly past the threaded portion into the unthreaded portion, such that it spans the point of stress concentration between the threaded and unthreaded portions. In yet another embodiment, a threaded fastener having a head and a threaded shaft has an aperture extending through the head and partially through the threaded shaft. The aperture has a diameter substantially equal to a width of a recess sized to receive a wrench. The aperture may have a shape such that it can also be gripped by a wrench.

Abstract: A compact, portable, aerosol contaminant extractor having ionization and collection sections through which ambient air may be drawn at a nominal rate so that aerosol particles ionized in the ionization section may be collected on charged plate in the collection section, the charged plate being readily removed for analyses of the particles collected thereon.
