摘要:
The present invention relates to a device, such as a decal, for releasing an agent capable of being sensed through olfaction, generally in conjunction with the use, application, or presence of water or water vapor, as in a shower, spa, bath tub, sink, sauna, basin, or the like. The decal includes a web and an agent that can be released, transmitted, or delivered so that the agent can be sensed or detected through olfaction. The decal further includes an affixation element, such as a bonding material, that attaches the decal to a surface. In some embodiments, the agent may be attached to the web while in other embodiments the agent may form part of the web. In one embodiment, the agent is menthol. In another embodiment, the agent is menthol and is accompanied by a material capable of effervescing. In yet another embodiment, the device for releasing an agent capable of being sensed through olfaction is attached to fixtures or molded surfaces that are typically associated with showers, baths, sinks, etc. (e.g., a shower head, the hot and/or cold levers or handles for activating the flow of water, hardware associated with a shower curtain or door, a spigot, molded handles, and the like). In still another version of the invention, that portion of the device that is associated with the agent may be adjusted along some length of the device. For example, a decal may be adjustably attached to a flexible cord or substantially stiff rod or frame, the cord, rod, or frame capable of being attached to one of the aforementioned fixtures or molded surfaces.
摘要:
A process and apparatus for determining the tension in a moving web is provided. The process includes the step of providing a web that is moving at a determined speed. The speed has a determined basis weight. A wave is created in the moving web. The speed of the propagation of the wave is determined. Also, the tension on the moving web is determined through a mathematical relationship between the wave speed, the basis weight of the web, and the speed of the web. The instability index of the web is greater than or equal to 0.5. The apparatus includes an air pulse for applying a pulse of fluid to the web to create a wave in the web. At least two laser displacement transducers are present. The laser displacement transducers measure the displacement of the web as the wave moves through the web. A computer is present which obtains signals from the at least two laser displacement transducers. The computer calculates the instability index in the web based on the speed of the wave in the web and the speed of the web.
