Abstract: A hinge for a door of a storage unit and a method of repairing a storage unit that includes a pivotable door. The hinge including a first bracket and a second bracket. The hinge further including a linking mechanism for coupling the second bracket to the first bracket so that the second bracket is able to translate and rotate relative to the first bracket, wherein a maximum amount of rotation of the second bracket relative to the first bracket is not determined solely by operation of the linking mechanism.

Abstract: An apparatus for treating air includes a housing with an air inlet and an air outlet, the housing enclosing an air treatment zone and an ozone removal zone, wherein the ozone removal zone is positioned downstream of the air treatment zone with respect to a flow direction of the air being treated, an ozone generator in the air treatment zone configured to generate ozone from the air, wherein the ozone generated by the ozone generator treats the air in the air treatment zone, catalyst in the ozone removal zone that removes at least a portion of the ozone generated the ozone generator, a particle matter (PM) filter positioned between the air treatment zone and the ozone removal zone, wherein the ozone generated by the ozone generator treats the PM filter, and an air mover positioned near the air outlet configured to draw the air through the air inlet.

Abstract: A three-dimensional printer positions a tool such as an extruder in three-dimensional space using a passive, i.e., non-motorized, z-axis alignment technique that generates z-axis movement based upon motorized movements along another axis. In this manner, intermittent z-axis step movements such as those from layer to layer in a multi-layer fabrication process can be performed without the need for an additional, dedicated motor for z-axis movement. The passive system may employ a variety of different gearing techniques to convert x-axis or y-axis movements into a z-axis movement under various conditions. For example, the three-dimensional printing tool may move to a predetermined position along a first axis (e.g., an x-axis or y-axis) where a passive gear assembly engages a rack or the like. When in this predetermined position along the first axis, the tool can move along a second axis and create a resulting movement on a third axis (e.g., the z-axis).
