Appl. No.:

6/039209

Inventors:

James L. Bartlett - Santa Barbara CA

Assignee:

Hydranautics - Goleta CA

International Classification:

B01D 3100

US Classification:

210321R

Abstract:

This invention relates to a reverse osmosis membrane module for separating a selected fluid component from a feed stock. The module comprises a mandrel having an axial passageway forming a flow path for the selected fluid component through the mandrel. A flow guide means is attached to the mandrel and forms a channel for the selected fluid component as it flows through the membrane module. A plurality of generally rectangular membrane envelopes are joined to the flow guide mandrel and are formed from a plurality of elongated permeate collector sheets each forming a flow path for the selected fluid component from the outer periphery of the envelope to the flow guide. A plurality of folded sheets of support material with each sheet having predetermined membrane areas where reverse osmosis occurs are joined to the collector sheets so as to form the membrane envelope. Each sheet of support material is formed such that there are no fold lines on the membrane areas where reverse osmosis occurs. Finally, a flow guide spacer is disposed between adjacent envelopes such that one end of each of the flow guide spacers is located in the area where the support sheet is folded and where no reverse osmosis takes place.

International Classification:

US Classification:

331 17

Abstract:

A frequency stabilizer circuit in the form of a charge-pump phase-lock loop utilizing a MEMS capacitance device, preferably a tunable MEMS capacitor or a MEMS capacitor bank, which more rapid and with a greater precision determine the phase and frequency of a carrier signal so that it can be extracted, providing an information signal of interest. Such MEMS devices have the added advantage of providing linear capacitance, low insertion losses, higher isolation and high reliability, they run on low power and permit the entire circuit to be fabricated on a common substrate. The use of the MEMS capacitance device reduces unwanted harmonics generated by the circuit's charge pump allowing the filtering requirements to be relaxed or perhaps eliminated.

Abstract:

An integrated, tunable inductance network features a number of fixed inductors fabricated on a common substrate along with a switching network made up of a number of micro-electromechanical (MEM) switches. The switches selectably interconnect the inductors to form an inductance network having a particular inductance value, which can be set with a high degree of precision when the inductors are configured appropriately. The preferred MEM switches introduce a very small amount of resistance, and the inductance network can thus have a high Q. The MEM switches and inductors can be integrated using common processing steps, reducing parasitic capacitance problems associated with wire bonds and prior art switches, increasing reliability, and reducing the space, weight and power requirements of prior art designs. The precisely tunable high-Q inductance network has wide applicability, such as in a resonant circuit which provides a narrow bandwidth frequency response which peaks at a specific predetermined frequency, making possible a highly selective performance low noise amplifier (LNA), or in an oscillator circuit so that a precise frequency of oscillation can be generated and changed as needed.
