  • Patent number: 9194392
    Abstract: A liquid ring pump includes an external housing enclosing a volume including a lower fluid reservoir. A rotatable inner housing is within the volume of the external housing, the inner housing enclosing an inner fluid chamber. A pitot tube provides fluid communication between the lower fluid reservoir and the inner fluid chamber. The housings and pitot tube are adapted so that when the inner housing rotates, fluid flows from the lower fluid reservoir through the pitot tube into the inner fluid chamber to develop a liquid ring within the inner fluid chamber such that an inner radial wall of the liquid ring is just radially outward from a point where the pitot tube enters the inner fluid chamber.

  • Patent number: 9186598
    Abstract: A novel pressurized vapor cycle for distilling liquids. In some embodiments, a liquid purification system is revealed, including the elements of an input for receiving untreated liquid, a vaporizer coupled to the input for transforming the liquid to vapor, a head chamber for collecting the vapor, a vapor pump with an internal drive shaft and an eccentric rotor with a rotatable housing for compressing vapor, and a condenser in communication with the vapor pump for transforming the compressed vapor into a distilled product. Other embodiments are directed toward heat management, and other process enhancements for making the system especially efficient.

  • Publication number: 20150321500
    Abstract: A pocket folder with increased document capacity and method of manufacturing same is disclosed. The folder has two cover panels 14-16, joined along a longitudinal joint or score line, a pair of pocket flaps 40a-40b and a top flap 70. Top flap 70 folds along a score line 72a-72b and a midline score 74 and a plurality of parallel scores 78 to accommodate expansion. At the pockets, a v-shaped notch 52 between the pockets prevents bunching and a circular cut away 90a-90b provides greater access to the documents.

  • Patent number: 9124682
    Abstract: Example embodiments of the present invention may include a method and apparatus configured determine an optimal routing path to route a call through a network. One example method may include retrieving and parsing a routing table and storing the parsed routing information in a routing database. The method may also include determining a plurality of routes that could be used to route the call through the network by applying at least one cost metric to the plurality of determined routes. The method may also include determining an order of the plurality of routes used to route the call, and create a route used to route the call based on the determined order of the plurality of routes.

  • Patent number: 8870549
    Abstract: Reciprocating positive-displacement membrane pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid are disclosed. The speed of a pump stroke can be adjusted by altering a frequency of pressure pulses delivered to the pump membrane during a fill stroke or a delivery stroke of the pump. A pumping algorithm may divide a pump stroke into an initial pumping period and a end-of-stroke pumping period, with the pressure pulse duration being longer during the initial pumping period. This arrangement may allow for a minimum pump flow rate while also providing a pressure ripple that can be used to detect the end of a pump stroke.
