摘要： The present invention relates to a visual indicating device and an article for controlling odors, in particular foot, garbage, basement, cooking, pet, tobacco, feces and urine odors. The article comprises a visual indicating agent that is color sensitive to the odor, and optionally, an odor absorbing agent. The visual indicating agent changes color when the article has been exposed to a sufficient amount of odor to saturate the article. The indicating agent may be applied in differing concentrations to two or more zones so as to indicate to a user of the article how much of the odor absorbing capacity has been used, or conversely, how much of the odor absorbing capacity remains. Suitable visual indicating agents that change color in response to odors are also described. The article for controlling odors may be a disposable odor absorbing sheet, air freshening product, diaper, undergarment pad, face mask, air filtration device, sanitary napkin, tampon, panty shield or incontinence pad.
摘要翻译：本发明涉及视觉指示装置和用于控制气味，特别是脚，垃圾，地下室，烹饪，宠物，烟草，粪便和尿气的气味物品。该物品包括对气味具有颜色敏感性的视觉指示剂，以及任选的气味吸收剂。当物品暴露于足够的气味以使物品饱和时，视觉指示剂改变颜色。指示剂可以以不同的浓度施用于两个或更多个区域，以便向用户指示已经使用了多少气味吸收能力，或相反地，残留了多少气味吸收能力。还描述了响应于气味改变颜色的合适的视觉指示剂。用于控制气味的物品可以是一次性气味吸收片，空气清新产品，尿布，内衣垫，面罩，空气过滤装置，卫生巾，卫生棉条，内裤护罩或失禁垫。

摘要： A method of preparing metal-modified silica particles is disclosed. Specifically, a treatment chamber is provided in which a first and a second formulation are ultrasonically mixed to prepare metal-modified silica particles. The treatment chamber has an elongate housing through which the first and second formulations flow longitudinally from a first inlet port and a second inlet port, respectively, to an outlet port thereof. An elongate ultrasonic waveguide assembly extends within the housing and is operable at a predetermined ultrasonic frequency to ultrasonically energize the formulations within the housing. An elongate ultrasonic horn of the waveguide assembly is disposed at least in part intermediate the inlet and outlet ports, and has a plurality of discrete agitating members in contact with and extending transversely outward from the horn intermediate the inlet and outlet ports in longitudinally spaced relationship with each other. The horn and agitating members are constructed and arranged for dynamic motion of the agitating members relative to the horn at the predetermined frequency and to operate in an ultrasonic cavitation mode of the agitating members corresponding to the predetermined frequency and the formulations being mixed in the chamber.

摘要： A skin sealant composition having a film former like cyanoacrylate and a goniochromic dye or pigment is provided. The addition of mica/metal oxide powders to the sealant formulation makes it possible to see where it has been applied, due to the mica/metal oxide's goniochromic (e.g. irridescent or pearlescent) appearance, and it is also still possible to view the underlying skin, especially from an angle at which the color is less apparent. Thus, mica/titanium dioxide or other goniochromic or light interfering particles may be used as an additive to allow for determination of complete coverage, while not significantly obscuring the incision site.

摘要： A wipe that includes a bacteriostatic agent that contains cations having an affinity for the negatively charged cell walls of bacteria is provided. The affinity of the bacteriostatic agent for the bacteria allows the wipe to capture bacteria, thereby removing them from a surface and also inhibiting their spread to other surfaces that may contact the wipe. Of particular advantage, the bacteriostatic agent may help protect against the spread or infection of pathogens without the use of chemicals, such as antiseptics or antibiotics. Still further, the wipe of the present invention also contains a solvatochromatic indicator that undergoes a color change in the presence of a broad spectrum of bacteria. Thus, when the wipe captures bacteria, the indicator undergoes a color change that signals to the user that the wipe is functioning properly. The lack of a color change may likewise provide the user with the assurance that the area is generally free of bacteria and clean.
摘要翻译：提供了包含具有对细菌带负电荷的细胞壁具有亲和性的阳离子的抑菌剂的擦拭物。抑菌剂对细菌的亲和力允许擦拭物捕获细菌，从而从表面除去它们，并且还抑制它们扩散到可能接触擦拭物的其它表面。特别有利的是，抑菌剂可以帮助防止病原体的扩散或感染而不使用诸如防腐剂或抗生素的化学物质。此外，本发明的擦拭物还含有在广谱细菌存在下经历颜色变化的溶剂色素指示剂。因此，当擦拭物捕获细菌时，指示器经历颜色变化，向用户发出指示擦拭物正常工作的颜色变化。缺少颜色变化也可以为用户提供该区域通常没有细菌和清洁的保证。
