Title: Method for fiber loading a chemical compound
Inventor: KLUNGNESS JOHN H
IPC: D21H17/67
Filed: 1992-03-05
Abstract: The present invention relates to a method for loading a chemical compound within the fibers of a fibrous material and to the fibrous materials produced by the method. In the method, a fibrous cellulose material is provided which consists of a plurality of elongated fibers having a fiber wall surrounding a hollow interior.  The fibrous material has a moisture content such that the level of water ranges from 40-95 % of the weight of the fibrous material and the water is positioned substantially within the hollow interior of the fibers and within the fiber walls of the fibers. A  chemical is added to the fibrous material in a manner such that the chemical is disposed in the water present in the fibrous material. The fibrous material is then contacted with a gas which is reactive with the chemical to form a water insoluble chemical compound. The method provides a fibrous material having a chemical compound loaded within the hollow interiors and within the fiber walls of the plurality of fibers.

Patent CA-2117205-A1 (CA)
Inventor: WAGNER ROBERT F
IPC: A47C27/06
Filed: 1994-03-08
Abstract: An elongate member of resilient material for use in the innerspring of a mattress, cushion or the like, is inserted between adjacent springs rows with its major cross-sectional axis extending perpendicular to the support surface. The cross-section of the resilient member is such that it increases from a minimum at or near the ends of a major axis to a minimum along a minor axis. The method of making the resilient member further contemplates matching the combination of cross-section and type of resilient material to the spring rate of the springs between which the member extends. When placed as a beam between springs defining the innerspring perimeter and interior springs adjacent thereto, this arrangement results in an assembly with a border of greater firmness, without a significantly harsh transition between compression of the border area and the innerspring interior area.

Title: Colored composition mutable by ultraviolet radiation
Inventor: NOHR RONALD S
IPC: C09K9/00
Filed: 1994-05-10
Abstract: Abstract of the Disclosure A colored composition which includes a colorant, an ultraviolet radiation transorber, and a molecular includant having a chemical structure which defines at least one cavity. Each of the colorant and ultraviolet radiation transorber is associated with the molecular includant. In some embodiments, the colorant is at least partially included within a cavity of the molecular includant and the ultraviolet radiation transorber is associated with the molecular includant outside of the cavity, e.g., the ultraviolet radiation transorber is covalently coupled to the molecular includant. The colorant, in the presence of the ultraviolet radiation transorber, is adapted, upon exposure of the transorber to ultraviolet radiation, to be mutable. The ultraviolet radiation transorber is adapted to absorb ultraviolet radiation and interact with the colorant to effect the irreversible mutation of the colorant. By way of ex-ample, the colored composition can be incorporated into a toner adapted to be utilized in an electrophotographic process. The toner includes the colorant, ultraviolet radiation transorber, and molecular includant as just described, and a carrier. The carrier can be a polymer, and the toner may contain a charge carrier. The ultraviolet radiation in general will have wavelengths of from about 100 to about 375 nanometers. Especially useful ultraviolet radiation is incoherent, pulsed ultraviolet radiation produced by a dielectric barrier discharge excimer lamp.

Title: Video if amplifier with auxiliary if amplifier for intercarrier sound and automatic fine tuning
Inventor: HARFORD JACK R
IPC: H04N5/44
Filed: 1993-10-30
Abstract: In a television receiver a downconverter responding to a selected television signal respectively supplies its first and second output signals as the input signals of first and second IF amplifiers, respectively. The downconverter includes a local oscillator for generating oscillations at a frequency controlled in response to the automatic fine tuning (AFT) signal. The first IF amplifier includes a first adjacent-channel sound carrier trap, in consequence whereof the first-IF-amplifier response is substantially reduced for the downconverted picture carrier, and an in-channel sound carrier trap.      Responsive to the first-IF-amplifier response, a video detector generates a composite video signal in which sound beats are suppressed to relatively low level by the first adjacent-channel sound carrier trap. A second IF amplifier includes a second adjacent-channel sound carrier trap. The second-IF-amplifier response, from which in-channel sound carrier is not trapped, is not as much reduced for the downconverted picture carrier by the second adjacent-channel sound carrier trap as the first-IF-amplifier response is by the first adjacent-channel sound carrier trap. From the second-IF-amplifier response, intercarrier detection circuitry detects an intercarrier-sound-IF response, which is amplified by an intercarrier sound-IF amplifier and then detected by an FM sound detector. Responsive to the second-IF-amplifier response, an automatic fine tuning (AFT) detector generates the AFT signal used to control the frequency of the oscillations generated by the local oscillator that the downconverter includes.

Title: Complex Cepstrum Analyzer for Speech Signals
Inventor: MITOME YUKIO
IPC: G01R23/16
Filed: 1995-02-14
Abstract: Respective samples of input speech data are transformed by a discrete Fourier transformer to obtain a spectrum of the speech data.  Simultaneously, values of times of the respective samples are multiplied with the input speech data by a multiplier and a differential spectrum is obtained by transforming a result of the multiplication by a discrete Fourier transformer.          A real part of a value obtained by dividing the differential spectrum by the spectrum by a quotient real part calculator and the real part is inverse-transformed by a discrete inverse Fourier transformer.          The result of the inverse-transformation is divided by the values of the times of the respective samples to obtain a time function corresponding to phase.          On the other hand, a time function corresponding to a logarithmic amplitude spectrum is obtained from an output of the inverse-Fourier transformer by means of a logarithmic amplitude spectrum calculator.  A complex cepstrum is obtained by adding the both time functions at respective times by an adder.
