  • Patent number: 5256211
    Abstract: The present invention is directed to a process for rapidly field annealing ferromagnetic cores and the cores produced thereby. A current is applied across a magnetizing source associated with a magnetizing core which induces a flux/voltage in the ferromagnetic core which is disposed about a leg of the magnetizing core. The flux/voltage in the second core induces a current in the second core which in turn induces a field in, and transverse to the width direction of, the ferromagnetic core. A second field may e applied to the ferromagnetic core during cooling. The cores produced display low core loss and either sheared over or square loop properties which are suitable for current and distribution type transformers respectively.

  • Patent number: 5252144
    Abstract: The present invention relates to a novel heat treatment process, and the alloy products produced thereby. The heat treatment process includes heating an alloy at a temperature and for a time sufficient to cause crystallization, cooling the alloy at a rate greater than about 10.degree. C. per minute, preferably greater than about 50.degree. C. per minute, and most preferably greater than about 100.degree. C. per minute. Alloys of many compositions and having either amorphous, surface crystallized or partially bulk crystallized structure may be beneficially treated. Alloy strips and cores heat treated according to the present invention display B-H loops which display a discontinuous change in slope at near zero field conditions. Alloy strips which have been heat treated according to the present invention display greatly increased resonant output voltages and are particularly useful as resonant markers in article surveillance systems.

  • Patent number: 4818680
    Abstract: A diagnostic reagent is disclosed which is capable of binding to a target nucleotide sequence which is bound to a labeled polynucleotide in a target binding region which is at least partially co-extensive with the target binding region in the probe polynucleotide which is capable of binding to the target nucleotide sequence. A method is disclosed in which the reagent is contacted with a sample and with a capturing polynucleotide under conditions such that target nucleotide which may be present in the sample binds to the probe polynucleotide and displaces labeled polynucleotide from the reagent complex, and the capturing polynucleotide binds selectively to the displaced labeled polynucleotide in the region of the labeled polynucleotide that had been bound to the probe polynucleotide. Determination of the displaced nucleotide gives a value which is a function of the presence and concentration of target nucleotide in the sample.

  • Patent number: 4629887
    Abstract: A radio frequency excitor apparatus and method produce an inductively coupled plasma to heat an analytic sample. The apparatus includes a radio frequency generator mechanism for producing electrical power of selected radio frequency. The generator mechanism has a power output tuning mechanism comprised of at least one output tuning inductor for determining the generator radio frequency. A separate plasma load circuit is coupled to the generator mechanism and is comprised of a work coil and a series connected, impedance matching capacitor. The work coil is adapted to produce an inductively coupled plasma and the capacitor is adapted to substantially balance the combined inductive reactances of the work coil and plasma. A control mechanism for controlling the power input into the plasma load circuit stabilizes the plasma.

  • Patent number: 4615225
    Abstract: A method and apparatus for measuring the constituent elements of a liquid, electrically conductive material includes a probe housing, which delimits a sampling chamber constructed to contain a non-reactive gas, and includes an entry mechanism for introducing aliquot of the liquid material into the sampling chamber. An inner housing is located within the probe housing and is moveable longitudinally relative thereto. A housing adjustment mechanism selectively positions the inner housing longitudinally relative to the probe housing. A spark electrode is disposed within the inner housing and is in communication with the sampling chamber. This electrode is longitudinally moveable relative to the inner housing and is constructed to spark an electrical arc discharge between the spark electrode and the free surface of the liquid aliquot, thereby producing a aerosol sample composed of particles of the material in the gas.

  • Patent number: 4510005
    Abstract: The end face of an optical fiber is urged against the highly polished surface of a disk as a laser beam is directed toward the disk to heat the end face above its softening temperature and cause it to conform to the contour and finish of the highly polished surface. A termination ferrule may be simultaneously mounted on the fiber optic cable with a heat bonding agent, using as a heat source either the laser beam or an auxiliary heat source. A hand-held, gun-type unit with a built-in disk and triggered laser can be used to polish and terminate optical fibers in the field.

  • Patent number: 4481069
    Abstract: Large single crystals of berlinite are grown onto seed crystals by maintaining the crystals at a fixed elevated temperature in a pressure vessel containing a nutrient of coarse berlinite crystalline powder, held at a fixed lower temperature, and a mixture of hydrochloric and phosphoric acids. Because berlinite shows retrograde solubility in the acid mixture, the nutrient goes into solution, and berlinite deposits on the higher-temperature growing crystal. Large single crystals of alpha-gallium orthophosphate may be grown using the same apparatus and a similar process. The resultant crystals may be cut into wafers useful in surface acoustic wave devices.

  • Patent number: 4190612
    Abstract: Beta pinene is converted to alpha pinene in liquid sulfur dioxide. The process is a regioselective isomerization of organic compounds having a carbon-carbon double bond at a tertiary carbon atom, by sulfur dioxide-induced allylic rearrangement of a hydrogen atom and/or replacement of a proton in the allylic position by a deuteron. The organic compound is contacted with sulfur dioxide at temperatures between about 0.degree. and 70.degree. C. for a time sufficient to effect such isomerization to a more stable isomer; and if deuteration is to take place D.sub.2 O is provided in the solution.

  • Patent number: 4167461
    Abstract: A system for the photoenhanced reduction of nitrogen. A p-type semiconductor cathode with a band gap between about 0.8 and 3.0 eV is irradiated with light falling within such energy range. The cathode is in contact with an electrolyte and capable of injecting photogenerated electrons into the electrolyte. An anode provides for removal of the resulting holes from the cathode. Cathode and anode are short circuited. For nitrogen molecule reduction, the electrolyte solution contains a chemical species capable in reduced form of chemically binding molecular nitrogen and of facilitating a series of reduction steps on the nitrogen. Specifically, such a chemical species is titanium isopropoxide.
