A method for detecting the onset of ovulation in a female mammal is provided. The method comprises contacting mouth air of the female mammal with an arylmethane test chromogen in an amount effective to undergo a rapid and detectable color change in the presence of one or more volatile sulfur compounds. The color of the test chromogen is compared to a control color that corresponds to a pre-ovulatory sulfur content. The difference in color between the test chromogen and the control color is correlated to the onset of ovulation.

A tablet that is capable of reducing odor when added to a liquid is provided. The deodorizing tablet may be used in a wide variety of applications in which odor control is desired, such as in toilets, water treatment/sewage systems, well water, bedpans, and so forth. In addition to providing odor control, the tablet is generally soluble in the liquid so that its components are better able to contact malodorous compounds contained within the liquid. In this regard, the present inventors have discovered that certain quinone compounds are both odor inhibiting and also soluble in liquids (e.g., urine), and thus particularly useful in forming the deodorizing tablet of the present invention.

The present invention provides a low-cost system and method for detecting substances within a mouth that influence oral health. The system and method also treat the mouth when certain substances are detected within the mouth. In some forms, the system includes a holder, a sensor that is attached to the holder and an oral treatment that is secured by the holder. The sensor detects a substance that influences oral health when the system is placed near a mouth. The oral treatment engages the mouth to treat the mouth when the substance is detected within the mouth. The method includes placing the system near a mouth and detecting the presence of a substance that influences oral health using the sensor. The method further includes treating the mouth using the oral treatment.

An odor control substrate that is applied with an activated carbon ink is provided. The activated carbon ink is applied in a pattern that covers from about 25% to about 95% of the surface area of the substrate. Although not covering the entire surface, the present inventors have discovered that the activated carbon ink is still capable of providing good odor reduction qualities to the substrate. To further enhance the aesthetic appeal of the odor control substrate to a consumer, one or more colored inks may also be applied the substrate in a pattern that may or may not overlap with the activated carbon ink pattern. The colored ink(s) may contrast well with the activated carbon ink to provide an overall design that is more aesthetically than otherwise would be provided by a uniform coating of activated carbon ink.

A portable folding field stand for supporting multiple fully assembled paintball markers by their barrels and air tanks in a horizontal, upright position; consisting of a rectangular base section; a barrel support bulkhead; and a tank support bulkhead. The base section is hingedly attached along one edge to the barrel support bulkhead edge and along an opposing edge to the tank support bulkhead. The tank support bulkhead has uniformly spaced tank support yokes, and the barrel support bulkhead has corresponding barrel support yokes. The bulkheads are foldable on the base section between two positions, open for use and closed for transport or storage. Both bulkheads have L shaped profiles that extend the available underside area of support when open and provide a suitcase-like profile to the stand when closed. The barrel support yokes are individually vertically adjustable to accommodate different markers.

A coating composition that is incorporated into a facemask to reduce fogging and glare is provided. For example, in one embodiment, the facemask contains a shield or visor formed from a transparent substrate having at least one surface applied with the coating composition of the present invention. The present inventors have unexpectedly discovered that one or more water-soluble organic polymers, such as ethyl hydroxyethylcellulose, may be utilized as a principal component of the coating composition to reduce fogging and glare in a simple, yet effective manner.

An odor control composition that comprises an odor-reducing quinone compound and optionally high surface area particles is provided. In one embodiment, the odor-reducing quinone compound is an anthraquinone having the following structure: wherein the numbers 1 through 8 refer to optional substitution positions for functional groups. For example, positions 5 through 8 of the anthraquinone may be unsubstituted with functional groups. Examples of such quinone compounds may include those obtained from a dye selected from the group consisting of Acid Blue 25, Acid Green 41, Acid Blue 45, Mordant Violet 5, Acid Blue 129, Acid Green 25, D&C Green No. 5, Acid Green 27, and combinations thereof.
摘要:
This invention concerns coatings having high surface area materials and at least one metal ion adsorbed onto the high surface area material as well as substrates having the coating and methods of applying the coating. The substrates may be films, woven fabrics or may be nonwoven fabrics. The coatings have good odor and/or gas absorbing capabilities. Nonwoven fabrics include tissues, towels, coform materials, bonded carded webs, spunbond fabrics and so forth. The substrates may be made into storage and packaging material to reduce odor and retard the ripening of fruit. The substrates may be used in personal care products, to produce clothing for military and civilian applications and many other applications.

The invention provides a breath testing device which visually indicates the presence of ammonia in a patient's breath, in particular ammonia from helicobacter pylori urease infection. The breath testing device comprises a visual indicating agent which changes color in response to ammonia odors, such as 4,4′-bis(dimethylamino)-benzhydrol (Michler's hydrol or BDMB), pararosaniline base and alpha-naphtholbenzein. The indicating agent is applied to a substrate which is then inserted into a tube or straw, which can be attached to the inlet of a breath collection balloon. When the patient blows into the tube or straw, the indicating agent will change color if it detects levels of ammonia which are consistent with helicobacter pylori urease infection.
摘要:
A method for reducing odors is provided. In one embodiment, the method comprises contacting a substrate containing a thin coating of colloidal nanoparticles with an odorous compound. The colloidal nanoparticles have an average size of less than about 500 nanometers, a surface area of from about 50 to about 1000 square meters per gram, and a pore volume of less than about 0.5 milliliters per gram. The colloidal nanoparticles may adsorb at least about 25% of the odorous compound when contacted therewith.
