  • Multi-chambered supercritical fluid extraction cartridge
    Patent number: 5932095
    Abstract: A multiple chamber sample holding cartridge is used with a supercritical fluid extractor that causes membranes dividing the cartridge into chambers to rupture upon the pressurization of the sample cartridge, thereby allowing the intermixing of materials contained in the chambers. The neutral oil and loss determination of soybean and other oilseed oils by supercritical fluid extraction is efficient with this two-chambered sample cartridge.

  • Automatic impedance modification of transmission lines
    Patent number: 4004102
    Abstract: An automatic impedance matching network for a transmission line includes an impedance monitor which provides a control signal for two variable compensators. One compensator corrects an impedance mismatch at low frequencies while the second compensates within a higher frequency range. A directional sensor completes a conductive path for the control signal to the variable compensators only for the direction of signal propagation indicative of the impedance of the transmission line being compensated. The disclosed arrangement operates automatically from the intelligence signals transmitted over the line to provide impedance compensation for a variety of cable sizes of different lengths.
