Abstract: Methods and apparatus for use of a fill on demand ampoule are disclosed. The fill on demand ampoule may refill an ampoule with precursor concurrent with the performance of other deposition processes. The fill on demand may keep the level of precursor within the ampoule at a relatively constant level. The level may be calculated to result in an optimum head volume. The fill on demand may also keep the precursor at a temperature near that of an optimum precursor temperature. The fill on demand may occur during parts of the deposition process where the agitation of the precursor due to the filling of the ampoule with the precursor minimally effects the substrate deposition. Substrate throughput may be increased through the use of fill on demand.

Abstract: An adjustable plant hanger is disclosed having straps that support a pot in which plants are placed. The straps comprise two or more loops that are not fastened to a ring by which the plant hanger may be hung from an overhead hook. The loop straps pass through the adjustable element or sleeve which can slide up and down along the straps to make it easier to mount a larger pot inside the straps of the plant hanger, making it easier to level pot and adjust when needed. The adjustable element is also adjusted vertically to more safely hold pots of different sizes. The straps are connected to a support element located beneath a pot. The spacing element maintains the straps are spaced around the sides of a pot evenly in the plant hanger to assure that the pot will not easily fall from the hanger. The straps may be individually slid through the ring and adjustable element to level an irregular shaped or larger pot held in the plant hanger.
