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: A built-in apparatus and method for treating air including a housing with an air inlet and an air outlet. An air mover positioned near the air outlet is configured to draw the air through the air inlet. The housing encloses an air treatment zone, such as including an oxidizing zone, and an ozone removal zone positioned downstream of the air treatment zone and oxidizing zone. The air treatment zone includes UV light and/or ozone that partially oxidizes the chemical contaminants in the air treatment zone. A catalyst in the oxidizing zone oxidizes elements within the air treatment zone. The ozone removal zone includes a second, different catalyst material. A UV bulb that may or may not generate ozone is positioned within or downstream of the first and/or second catalyst materials to assist catalyst oxidation and/or self-clean the apparatus.

Abstract: An apparatus and method for cleaning contaminated air in an enclosed space, such as a transportation trailer or a shipping container. An air mover in the space circulates contaminated atmosphere from an area of low pressure to an area of higher pressure. The resulting pressure differential is used to draw a reverse, partial air flow through an air cleaning device. The repeated cycling of a portion of airflow results in cleaning of the atmosphere and a general reduction of the contaminant from the enclosed space.

Abstract: An oven includes a cooking enclosure including one or more cooking heater elements, a steam source in the cooking enclosure, and a steam source heater for the steam source. A sensor is responsive to the temperature of the steam source. A fluid reservoir is exterior to the cooking enclosure and a conduit extends from the fluid reservoir to or proximate the steam source. A controller energizes the steam source heater if the temperature of the steam source is below a predetermined threshold and de-energizes the steam source heater if the temperature of the steam source is above the predetermined threshold.

Abstract: An apparatus is provided for accurately dispensing a powder such as powdered infant formula into a container, and pasteurizing and reconstituting the powdered formula while completely mixing the formula in the container. The apparatus includes a hopper assembly for storing powder, a dosing assembly for measuring and dispensing powder from a receptacle into the container, a dilution assembly and a mixing assembly for obtaining accurately and completely mixed formula from the dispensed powder. The hopper is shaped to promote powder bridging, and the resulting powder bridge is used in combination with the dosing assembly to provide a predetermined amount of powder using a single mechanical valve that is isolated from the powder. The mixing assembly mixes the contents of the container while holding the bottle at a fixed angle relative to the vertical. A method of providing pasteurized infant formula from an infant formula powder is also disclosed.

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).
