  • Patent number: 4941477
    Abstract: A method and apparatus for detecting concealment of hidden information in interrogative polygraphy is described which employs Event Related Brain Potentials (ERP). Various stimuli are presented to a subject and the P300 components of the subject's ERP's are monitored and analyzed. Three types of stimuli are presented, Probe which are relevant to the "crime", Irrelevant--having no bearing on the crime, and Target which require the subject to perform an act. If, and only if, the subject has guilty knowledge, the Probe stimuli, like the Target stimuli, elicit a large ERP and provide a guilty indication.

  • Patent number: 4786597
    Abstract: Catalytic chemical and biochemical conversion reactions are carried out in a novel compartmentalized catalytic reactor which enables the energy-efficient coupling of the conversion reaction with various energy-consuming post-conversion operations. The catalytic reactor is compartmentalized by means of a multilayer composite membrane comprising a catalytic membrane layer and one or more permselective membrane layers. The arrangement and properties of the membrane layers are such as to enable the free energy change of the conversion reaction to be utilized as the required energy source for effecting various post-conversion operations, including product separation, recovery and enrichment, and second-stage catalytic conversions with unfavorable reaction equilibria.

  • Patent number: 4772884
    Abstract: An AC gas discharge display panel is described which employs the phenomenon of plasma spreading. In the panel, plasma spreading or "coupling" is employed to couple the plasma to an addressed cell to one of a plurality of pixels to be illuminated. The spreading is controlled by assuring that the cell wall voltages are properly related so that the plasma's electrons migrate to a region where the voltages are approximately equal to or more positive than the wall voltages where the plasma originated. Paired sustain electrodes are selectively energized to enable diversion of the coupled plasma to the desired pixel, so that upon subsequent applications of a sustain voltage, the desired pixel is illuminated (or erased) as the case may be.

  • Patent number: 4741746
    Abstract: An improved exhaust gas particulate removal system is described which includes a corona-charger that is spark-plug like in configuration. The charger includes a central electrode held within an insulating body, a portion of which electrode is recessed in a cavity formed in the insulating body. A very small amount of clean gas is introduced into the cavity in a manner so as to create a spiral vortex flow about the electrode. The swirling gas flow creates an over-pressure which prevents the exhaust particulate matter from depositing on either the needle electrode or the walls of the cavity. Another swirling air flow, surrounding the exterior of the insulating body, is also provided to prevent the formation of a continuous layer of soot deposit thereupon, with the aid of a cylindrical baffle. The charger is juxtaposed to a conductive attractor electrode to create the desired corona for particulate charging and the path of the exhaust flow is passed between the charger and attractor electrodes.

  • Patent number: 4740283
    Abstract: A pulsed-field gradient gel electrophoretic apparatus is described wherein a free standing gel is employed. Electrode arrays are oriented to provide three dimensional fields across the face of the gel rather than in the plane of the gel. The electrodes produce three dimensional fields which are orthogonally oriented with respect to each other and cause the molecules to proceed down the lanes in the gel in a generally saw-tooth manner oscillating between the surfaces thereof. Alternately, three dimensional, electric fields are arranged at angles greater than 90.degree. to one another across the face of the gel in separating the molecules, following which transfer electrodes are substituted for the separation electrodes in order to transfer the molecules from their separation lanes onto a separate substrate.
