Abstract: A hygienic powdered protein delivery system includes a pouch having a lightweight flexible material. One end of the pouch is tapered to form a funnel shape and is sealed before it is filled with protein powder. The pouch of protein powder is clamped at the bottom of a cupboard a corresponding receptacle. The tapered end of the pouch of protein powder is sliced and held in place by two pressure compression/clappers. The pressure clamps have a non-permanent adhesive that allows the tapered pouch to be pulled apart allowing the protein powder to flow out into a collector that contains a receiving container. The hygienic powdered protein delivery system has a number of slots that will support several pouches of protein powder. Each pouch can be rotated into the dispensing position. The dispenser enables a number of different types of protein to be dispensed in a hygienic manner never before achieved.

Abstract: A device for reducing sound from an air treatment unit includes, in one embodiment, an air treatment system, including a wall mount HVAC unit with a supply air opening and a return air opening. A supply air sound reducer is provided in communication with the supply air. The supply air sound reducer includes a housing defining a supply interior provided with sound reducing material. The sound reducing material is overlaid with a layer of perforated material. A return air sound reducer is provided in communication with the return air opening. The return air sound reducer includes a housing defining an interior return volume provided with sound reducing material applied to one or more inside surfaces of the interior return volume and a layer of perforated material disposed over the sound reducing material. Mid-structure including sound reducing material is disposed in each of the supply and return air assemblies.

Abstract: According to one or more aspects of DC-to-DC voltage conversion as taught herein, a DC-to-DC converter selectively operates in a first mode wherein an included linear pass output circuit supplies the output power from the DC-to-DC converter, in a second mode wherein an included charge pump output circuit supplies the output power, and in a third mode wherein the linear pass and charge pump output circuits operate in parallel to supply the output power. With this third mode, also referred to as a “dual” mode, wherein the linear pass and charge pump output circuits operate in parallel, the DC-to-DC converter keeps the more efficient output circuit on after it has begun switching to operation with the less efficient output circuit. Such switchover may be performed dynamically in response to changing operating conditions. Detected operating conditions may include input voltages, output voltages, and output load conditions.

Abstract: The present invention provides a process for preparation of a chelant composition by a non-spray-drying process, a process for improving one or more of flowability and scoopability of a laundry detergent composition, and a chelant agglomerate useful as an ad-mix in a particulate laundry detergent. In one aspect of the present invention, the process for preparation of a chelant composition by a non-spray-drying process includes the steps of admixing a transition metal chelant and an inorganic compound to form a mixture, aglomerating the mixture in an aqueous medium to form a chelant agglomerate and drying the chelant agglomerate.
