Abstract:
A system for reducing signal interference in modulated signal communication includes a measurement processor. The measurement processor measures amplitudes of noise components of a received amplitude modulated signal prior to demodulation. The measurement processor also identifies a frequency of a noise component having an amplitude larger than the amplitude of another noise component. A carrier frequency generator generates a carrier frequency substantially at a harmonic of the identified noise component. The carrier frequency is used to generate and demodulate the amplitude modulated signal.
Abstract:
Nonwoven materials having a pattern incorporated into the materials are disclosed. The nonwoven materials may be, for instance, tissue webs, meltspun webs such as meltblown webs or spunbond webs, bonded carded webs, hydroentangled webs, and the like. The pattern may be incorporated into the webs using various techniques. For instance, the pattern may be formed into the web by topically applying a bonding material. In an alternative embodiment, the pattern may be formed according to a thermal bonding process. The pattern contains individual cells that include two spaced apart expanded regions separated by a constricted region. By incorporating the pattern into the web, a material is produced having a relatively low Poisson ratio.
Abstract:
A method for recycling latex-containing broke is provided. Specifically, the present inventors have discovered that mechanical treatment may be employed to rework latex-containing broke for reuse in various products without the need for treatment with chemicals, such as hypochlorite, chlorine, or hypochlorous acid. As a result of mechanical treatment, fiber aggregates (e.g., combination of short fibers, fiber fragments, and/or latex) are formed that have a relatively small size. Besides having a reduced size, the fiber aggregates have also been unexpectedly discovered to have other unique properties. For instance, a large portion of the resulting fiber aggregates may be relatively free from the latex polymer. Specifically, the fiber aggregates contain a “core” of latex from which extend short fibers and/or fragments that are uncoated with the latex. The result is fiber aggregates that are uniquely “partially coated” with a latex polymer. When recycled in paper products, these fiber aggregates may impart a variety of benefits, such as increased bulk retention and high water capacity without any loss in absorbency rate.
Abstract:
The present invention is generally directed to base webs that are creped after a bonding material has been applied to at least one side of the web according to a predetermined pattern. According to the present invention, the bonding material contains a creping adhesive mixed with composite particles. The composite particles generally have a median particle size of less than about 5 microns and a particle size distribution of less than about 10 microns.
Abstract:
A process for manufacturing a cellulosic paper product (e.g., paper hand towels) exhibiting reduced malodor upon wetting. The process includes introducing a malodor inhibiting agent comprising isoascorbic acid and/or L-ascorbic acid antioxidants into the aqueous suspension of papermaking fibers from which the paper product is made, depositing the aqueous suspension of papermaking fibers onto a sheet-forming fabric to form a wet web and drying the wet web at high temperature in an oxidative environment to form a dried base sheet. The process of the present invention is particularly suited for reducing malodor released from cellulosic paper products made from through-air dried base sheet material.
Abstract:
This disclosure is concerned with the use of on-line simulation of circuit faults during diagnosis to generate a small part of a complete fault dictionary needed for diagnosis of the circuit, being adapted for use of a mini-computer-based automated test system having only a small amount of secondary storage; and being adapted for an exact match diagnosis with modeled failures, and a heuristic approach for a partial match of faulty behaviour that leads to a highly probable diagnosis.
Abstract:
A device for draining melted snow from a roof including an adjustable collector tube having means for securing it to a roof at the lower edge of the roof together with a screen unit mounted within the collector tube and spaced from a wall of the tube and means for maintaining a melting agent on the screen whereby ice built up to the screen is melted by the melting agent thereby causing the same to run out of the collector tube.
Abstract:
In a method for the processing of fish, poultry or other meat products being conveyed in a plurality along a processing line, components which are to be excluded from consumption are separated and edible products obtained as a result for consumption are checked with an automatic inspection device for residues left behind. Separation takes place in such a way that, in the case of a number of edible products, minimized residues of at least one kind are deliberately permitted and induced for further processing of the edible products, in particular to optimize the edible product recovery. The automatic inspection device is adjusted to detect the minimized tolerance residues, and inspected edible products with and without the tolerance residues are separated from each other. In an apparatus for carrying out the method, a separating device with at least one separating tool is designed in such a way that, in the case of a number of edible products, minimized tolerance residues of at least one kind are left behind for further processing of the edible products, and the inspection device is connected to a separator device which distinguishes edible products with and without residues according to the inspection results and discharges them separately from each other.
