  • Patent number: 6543483
    Abstract: A fluid handling port array includes at least one fluid conduction bore, a plurality of insert bores each intersecting at least one fluid conduction bore and being adapted to receive a configuration insert, a plurality of port bores each intersecting at least one of the fluid conduction bores for providing fluid access to the fluid conduction bores. The port array is configured by fixing configuration inserts in the insert bores. In a particular embodiment, the configuration inserts comprise device seats and are adapted to receive configuration devices such as a valves, caps or plugs. Alternatively, the configuration inserts, themselves, embody configuration devices.

  • Patent number: 6186745
    Abstract: The multi-chamber liquid pump of the present invention includes an input chamber, an intermediate chamber and a liquid output chamber. Pressurized gas provides the motive force for outputting liquid from the pump, such that liquid is output at a constant flow rate during pump operation. Liquid flows into the input chamber, through one or more valves into the intermediate chamber, and through one or more subsequent valves to the output chamber while liquid is constantly output from the output chamber. The system controller provides control signals to the valves to facilitate the pump's continual operation.

  • Patent number: 6148667
    Abstract: A carriage assembly provides for holding a pressurizable vessel used in delivering fluid to a processing system, the pressurizable vessel having an elongated body defining a longitudinal axis, a first end, and a second end. The carriage assembly includes: a support structure for holding the vessel such that the axis is non-vertical, the support structure being substantially isolated from mechanical vibration caused by the processing system; and a sensor coupled with the vessel and operative to generate a signal indicative of the amount of fluid stored in the vessel. The support structure provides a fulcrum proximate the first end of the vessel, and the sensor includes a load sensor mechanically coupled with a portion of the vessel which is located proximate its second end. The sensor is operable to generate the signal in response to force exerted on the load sensor by the weight of the vessel.
