  • Patent number: 5270032
    Abstract: A method for treating Candida infections of surfaces and cavities of dentures, the oral and vaginal cavities is disclosed. The method includes contacting an antifungal formulation onto the surface or cavity which is infected with the Candida fungus.

  • Patent number: 5270640
    Abstract: An improved method for detecting an incipient failure in a multiphase electric motor includes the following steps: periodically measuring or continuously monitoring voltage and current values at each input to the motor; determining negative sequence voltage and current values for each periodic measured input voltage and current value; calculating an effective negative sequence impedance phasor value angle from each of the determined negative sequence voltages and current values; and comparing the calculated negative sequence impedance phasor angles and/or real and imaginary components over a plurality of periodic measurements to detect a change therein, which change is indicative of an incipient failure mode.

  • Patent number: 5269189
    Abstract: The invention includes a means and method for transmitting and receiving broadband, unipolar, ultrasonic pulses for ultrasonic inspection. The method comprises generating a generally unipolar ultrasonic stress pulse from a low impedance voltage pulse transmitter along a low impedance electrical pathway to an ultrasonic transducer, and receiving the reflected echo of the pulse by the transducer, converting it to a voltage signal, and passing it through a high impedance electrical pathway to an output. The means utilizes electrical components according to the method. The means and method allow a single transducer to be used in a pulse/echo mode, and facilitates alternatingly transmitting and receiving the broadband, unipolar, ultrasonic pulses.

  • Patent number: 5270797
    Abstract: A method and apparatus for determining the characteristics of materials, particularly of semiconductors, semiconductor heterostructures and semiconductor interfaces by the use of photoreflectance, in which monochromatic light and modulated light beam reflected from the sample is detected to produce a d.c. signal and an a.c. signal, whereby the d.c. signal is applied to one input of a computer and the a.c. signal is used with another input of the computer which controls the light intensity of the monochromatic light impinging on the sample to maintain the d.c. signal substantially constant. A stepping motor is preferably utilized for varying the light intensity of the monochromatic light which is controlled by a computer to re-establish rapidly a predetermined d.c. signal established during normalization procedures when the light intensity of the monochromatic light changes, especially during change of its wavelength.

  • Patent number: 5267942
    Abstract: A method for interactively entraining a patient's heart rate to a target rate or frequency includes the steps of determining the patient's heart rate through a heart rate monitor and exposing the patient to music having a tempo within approximately one (1) beat of the heart rate. The heart rate is again determined, and if it has changed the tempo of the music is likewise changed in order to be within approximately one (1) beat of the heart rate. The process is continued until the target rate is reached. Vibrational bass tones can be added to enhance the entrainment. Similar methods can be used to entrain respiration rate and fundamental brain wave frequencies, in the latter case using continuous tones of music having repetition frequencies within the entrainment range.

  • Patent number: 5268621
    Abstract: A controller for an inchworm type linear transducer is constructed so as to be extremely low noise and to permit very fine positioning. This is done by storing the desired output waveforms in digital form in an EEPROM memory array and then counting through the address locations of the memory array to re-create the desired waveform. An analog amplifier is used to actually drive the piezoelectric elements in the transducer.

  • Patent number: 5268167
    Abstract: This invention involves the use of amorphous calcium compounds such as: amorphous calcium phosphate (ACP), amorphous calcium phosphate fluoride (ACPF) and amorphous calcium carbonate phosphate (ACCP) for use in remineralizing teeth. These amorphous compounds or solutions which form the amorphous compounds, when applied either onto or into dental tissue prevent and/or repair dental weaknesses such as dental caries, exposed roots and dentin sensitivity. The compounds have the highest solubilities, fastest formation rates and fastest conversion rates (to apatite) among all the calcium phosphorate under physiological conditions. Moreover, in the presence to fluoride the amorphous compound convert rapidly to fluoride containing apatite.

  • Patent number: 5268572
    Abstract: An ion trap mass spectrometer includes an ion trap region separated from an electron multiplier region by a baffle, and separate turbomolecular pumps for pumping each region to a different pressure level. The ion trap region can therefore be pumped to a higher pressure level than ca be used for the electron multiplier region, and the result and increase in pressure of damping gas in the ion trap region increases the sensitivity of the device.

  • Patent number: 5268954
    Abstract: A mounting mechanism for a double crystal monochromator or the like has a parallelogram based mounting mechanism in which two of the vertices of the parallelogram are fixed in position, and two vertices are free to translate back and forth in a straight line parallel to the fixed base of the parallelogram. One diffractor is mounting for pivoting at one of the fixed vertices, and the second diffractor is mounted for pivoting at an adjacent movable vertex. The surfaces of the diffractors are maintained parallel as the angle of the diffractors with respect to input and output beams to the monochromator is changed to change the wavelength being passed. The diffractor mounted at the fixed pivot may be connected to a large diameter wheel which in turn is connected by a band to a smaller diameter wheel mounted for rotation at the other fixed vertex of the parallelogram, with a pivotable arm connected to the smaller wheel to rotate therewith.

  • Patent number: 5268268
    Abstract: The presence or absence of a nucleic acid sequence of an isolate of HTLVI and/or HTLVII in a sample containing one or more nucleic acids and suspected of containing such sequence can be detected by amplifying the sequence using primers to form extension products as templates and detecting the amplified product if it is present. This may be accomplished by adding a labeled hybridization probe to the amplified product, either free in solution or after immobilization on a solid support.

    Abstract: Novel non-elastomeric biomedical adhesive compositions for calcified tissues, are described. The compositions are characterized by a network structure which is obtained by the reaction of a polyisocyanate having at least two isocyanate groups with at least one polyol which possesses surface wetting properties with the participation of compounds selected from calcium and phosphorus, optional in the presence of a catalyst. The polyisocyanate is selected from aliphatic, alicyclic and aromatic compounds and preferred amounts are in the range of 20% to 80% by weight of the total amount of reactants. The polyol is selected from polyalkylene ether glycols and polyester glycols containing between 25 to 75 carbon atoms and preferred amounts are in the range of 10% to 80% by weight of the total amount of reactants. The adhesive compositions were found to produce a fast bonding of the calcified tissues, with a joint strength of above 0.5 N/sq.mm.
