摘要： An infusion extractor is provided including a plunger to be inserted into an infusing container containing the infusion mixture that has vertical inner walls oriented parallel to a vertical axis of the container. The plunger includes a first surface with a seal situated at an edge of the surface. The seal is adapted for sealing against the inner walls of the infusing container as the plunger moves within the container, to define a first chamber containing the mixture of infusible material and extract. The plunger also includes a second surface extending from the first surface and defining a second chamber; the second surface includes extract flow openings which permit flow of extract from the first chamber into the second chamber. At least a portion of the extract flow openings are situated at a depth either above or below the first surface along the vertical axis.

摘要： A gas separation device is disclosed. In particular, seal assemblies and adsorbent element constructions for a gas separation device such as a pressure swing adsorption device are disclosed. The seal assembly can be part of a rotary valve and can include a seal backer and a floating seal positioned within a bore in the seal backer. The floating seal is configured to press towards and seal against an adjacent rotor. Valve action is provided as apertures in the floating seal and rotor are brought into and then out of alignment as a result of relative rotation therebetween. The seal assembly can include two types of gas chambers to apply balanced sealing pressures over the sealing surface of the valve, one type configured to receive pressurized process gas from within the device and the other configured to receive gas from an independently controlled pressurized gas source. The adsorber elements in the device may comprise improved spacer cross support structures at the ends of wound laminate adsorbent structures.

摘要： A typical rotary face seal employs a seal ring rotating relative to a sealing surface and also employs means to urge the seal ring towards the sealing surface in order to effect a seal. The seal ring may itself comprise a seal face bonded to a backing ring. In certain applications, the seal face may deform significantly as a result of the temperature variations experienced and an undesirable crowning of the seal face may occur. Such crowning may be reduced by employing an improved seal ring with anti-crowning features in which the thickness of an edge of the seal face is different from that in the middle of the seal face, or in which a relief slot is employed in the seal face. The improved seal ring is particularly suited for rotary face seals used in a rotary valve in a rotary gas separation device.

摘要： Pressure swing adsorption separation of a feed gas mixture, to obtain a purified product gas of the less strongly adsorbed fraction of the feed gas mixture, is performed with a cooperating set of "N" adsorbers in a rotary assembly, with each adsorber communicating at its product end directly to a rotary cyclic displacement chamber, and at its feed end by rotary distributor valve ports to a rotary piston feed compressor and a rotary piston exhaust vacuum pump. The compressor and vacuum pump are integrated with the cycle, and rotate at "N" times the cycle frequency. Alternative adsorber configurations for high frequency operation are disclosed.

摘要： A pressure balanced rotary valve can be made more compact if the ports on the stator within can be located on a port pitch circle of smaller diameter. In certain circumstances for rotary valves used in pressure swing adsorption devices, it is acceptable for the spacing between the ports to be made smaller than the ports themselves. In a rotary valve comprising variable loading means (e.g. pistons) and fixed loading means (e.g. springs), this can involve reducing the piston size and increasing the load provided by the springs.
