Title: Automated system and method for eliciting confidential information from a patient
Inventor: CUMMING PAUL D
IPC: G06F19/00
Filed: 1994-02-17
Abstract: Abstract of the Disclosure An automated computer system using audio and visual material for posing and recording answers to highly confidential questions to respondents.  The system allows a respondent to tune the system to his own sense of privacy through the choice of alternate audio devices - a speaker or a more private handset; volume controls; choosing to view the questions and supporting pictorial materials or to more privately hide them from view; choosing whether to have verbal feedback of their responses; and choosing the touchscreen response buttons or a more privately held touchpad.  The questions are available in multiple languages (English, Spanish, and others), and the sequence of questions is customized for the sex of the respondent and their new/repeat status.  The questions are mutually reinforced through three sets of materials - audio, text and visual, to maximize comprehension.  Respondents' access to response buttons is delayed until such a time that they have heard or read sufficient materials to understand the question.  The sequence and content of questions is controlled through an input file which can be easily modified.  As the questioning process proceeds each response and indirect information about each response are recorded so decision rules more complicated then just right/wrong answer can be implemented.

Title: Biological control of termites
Inventor: GUNNER HAIM
IPC: A01N63/30
Filed: 1993-07-29
Abstract: Methods have been developed for protection of structures from termite infestation. In the preferred embodiment, termites are attracted into contact with a potentially lethal fungus, such as Metarhizium anisopliae or Beauveria bassiana, using an attractant, such as the fungus Gloeophyllum trabeum or its volatile products. In another embodiment, a fungus is used which is naturally repellent to the termites, such as M. anisopliae and serves to prevent termites from entering into an area bounded by the repellent fungus. The entomopathogenic fungus, alone or in combination with an attractant fungus, is provided either in the form of an infection chamber or formulated with a nutrient composition and administered directly to inhabited galleries or to the termite nest to initiate infection, transmission and colony mortality.  Examples demonstrate control of termites using chambers containing M. anisopliae and B. bassiana.

Title: An optical regenerator and an optical transmission system
Inventor: TAKEYARI RYOJI
IPC: H04B10/588
Filed: 1995-01-30
Abstract: A a first clock extraction device included in the receiving section of the optical regenerator recovers a receiving clock. The receiving clock follows the fitter contained in a receiving optical signal caused by fiber wavelength dispersion. The receiving optical signal is detected in synchrony with the receiving clock. A transmission section includes a transmitter for generating a transmission optical signal changed in phase in such a manner as to suppress the stimulated Brillouin scattering and a second clock extraction device for regenerating the transmission clock not following the fitter. The data of the receiving optical signal is processed at a processing unit, and intensity-modulated on the basis of the data thus processed. The timing of this modulation is synchronized with the transmission clock. The receiving clock is synchronized with the fitter, and therefore no logic error occurs. Since the transmission clock does not follow the fitter, the fitter is prevented from accumulating.

Abstract: Concentration of a polyelectrolyte in the water of an aqueous system is controlled by first withdrawing a sample of the water and adding a known or standard amount of a fluorochromatic reagent to the sample. Then light energy is directed into the sample whereby light energy of a selected excitation wavelength for the fluorochromatic dye is available for absorption by the fluorochromatic reagent. The intensity of light emitted about a selected emission wavelength for the fluorochromatic reagent is measured and the intensity of the emitted light is compared to a standard curve, comprising a plot of fluorescence emission intensity of the fluorochromatic reagent in the presence of a polyelectrolyte versus concentration the polyelectrolyte. The concentration of the polyelectrolyte in the sample of water is determined from the comparison.

IPC: B22D11/01
Filed: 1995-03-31
Abstract: Abstract Programme-controllable electromagnetic continuous casting mould for producing con-tinuously cast ingots of various dimensions, featuring a dummy base of fixed dimensions that can be lowered and a mould frame having a pair of facing, stationary side walls and a pair of facing end walls the distance between which can be varied in a controlled manner; the side walls and the end walls together form the mould opening, and each of the walls comprises an inductor part with inductor coil and a screen. The mould frame exhibits at least one end wall that is displaceably mounted on the adjacent side walls, the inductor coils and the screens of the individual walls being connected to closed loops via flexible electrical conductors.   The position of the displaceable end walls can be determined at any point in time and the positioning of each end wall takes place by means of a drive regulated by a control unit, whereby during the casting process the distance between the end walls is regulated in conjunction with the rate of lowering the dummy base by programme control, this in such a manner that the cross-sectional dimensions of the resultant metal column change con-inuously or in a series of steps until the dimensions of the desired ingot are reached.

The dividing wall is provided with a set of dividing wall apertures extending therethrough. The dividing wall apertures are configured and sized so as to prevent the migration of the content of the container body from one carbonization half chamber to the other while allowing the passage of gases and of the incandescent combustion plane through the dividing wall. The container body is pivotally mounted on a kiln stand so as to allow the container body to be pivoted about a pivoting axis that extends substantially in register with the dividing wall.
