摘要： Environmental control in air handling systems that are required to provide highly effective filtration of noxious gases particularly within filter canisters that are ultrasonically welded enclosures is provided. In one embodiment, a filtration system utilizes a novel zeolite material that has been hardened to withstand ultrasonic welding conditions in order to reduce the propensity of such a material to destabilize and/or dust. Such a hardened zeolite thus enables for trapping and removal of certain undesirable gases (such as ammonia, ethylene oxide, formaldehyde, and nitrous oxide, as examples) from an enclosed environment, particularly in combination with metal-doped silica gel materials. Such a hardened zeolite is acidic in nature and not reacted with any salts or like substances and, as it remains in a hardened state upon inclusion within a welded filter device, the filter medium itself permits proper throughput with little to no dusting, thereby providing proper utilization and reliability for such a gas removal purpose. Methods of using and the application within specific filter apparatuses are also encompassed within this invention.

摘要： The present invention relates generally to an environmental control unit for use in air handling systems that provides highly effective filtration of noxious gases (such as ammonia). Such a filtration system utilizes novel undoped precipitated silica or silicon-based gels to temporarily trap and remove such undesirable gases from an enclosed environment and permit recycling of such gases subsequently thereto. Such precipitated silicas need to exhibit specific pore sizes, pore volumes, pore diameters, and particles sizes to be effective for such a purpose. The combination of these particular properties permits highly effective noxious gas filtration such that excellent uptake and breakthrough results are attained, particularly in comparison with prior media filtration products. Methods of using and specific filter apparatuses are also encompassed within this invention.

摘要： The present invention relates generally to an environmental control unit for use in air handling systems that provides highly effective filtration of noxious gases (such as ammonia). Such a filtration system utilizes novel metal-doped silica-based gels to trap and remove such undesirable gases from an enclosed environment. Such gels exhibit specific porosity requirements and density measurements. Furthermore, in order for proper metal doping to take effect, such gels must be treated while in a wet state. The combination of these particular properties and metal dopant permits highly effective noxious gas filtration such that uptake and breakthrough results are attained, particularly in comparison with prior silica gel filtration products. Methods of using and specific filter apparatuses are also encompassed within this invention.

摘要： Coated particles of metal (such as calcium) silicate that exhibit excellent odor neutralization and sebum absorption properties when present within certain cosmetic and/or personal care formulations and suspensions are provided. Uncoated calcium silicate exhibits a high pH level that may have a deleterious effect upon such cosmetic and/or personal care compositions, thereby rendering the overall composition ineffective for its intended purpose, particularly if the calcium silicate is present in its usual state at high loading levels. Alternatively, if certain materials present within personal care compositions exhibit a sufficiently low pH level, the effectiveness of such calcium silicates may be compromised as well. Such novel coated/treated calcium silicates thus permit high loadings of this beneficial odor neutralizing/sebum absorbing additive within cosmetic and/or personal care formulations without causing any appreciable instability issues or viscosity modification concerns or allow for coexistence with such low pH materials without any appreciable reduction in performance capabilities of the calcium silicates themselves. Certain personal care compositions comprising these novel coated calcium silicate particulates are encompassed within this invention as well.

摘要： New silica gel materials and novel methods of producing such are provided. The method itself entails a manner of mixing the reactants together in a one-pot process such that the time required for aging is reduced without compromising the ability to target pore size production. In such a way, the pH of the reaction drives pore size development, thereby permitting a more efficient process to be followed in terms of expensive drying/heating steps being reduced timewise, if not altogether. Furthermore, in one embodiment, the resultant gel materials exhibit a certain pore size minimum while simultaneously exhibiting a degree of softness heretofore unavailable. As such, not only is this novel method more efficient in silica gel manufacture, but the resultant materials are completely novel as well. The gel materials made therefrom may be utilized in a variety of different end uses, such as cooking oil filtration, soft skin cleansers, dental abrasives, and the like. Methods of production and use, as well as the novel gel materials themselves, particularly caustic and composite gels, are thus encompassed within this invention.
摘要翻译： 提供了新的硅胶材料及其生产方法。 该方法本身需要一种在一锅法中将反应物混合在一起的方式，使得老化所需的时间降低，而不损害目标孔径生产的能力。 以这种方式，反应的pH驱使孔径显影，从而允许在昂贵的干燥/加热步骤方面遵循更有效的方法，如果不是完全减少时间的话。 此外，在一个实施方案中，所得凝胶材料表现出一定的孔径最小值，同时表现出迄今为止不可用的柔软程度。 因此，这种新方法不仅在硅胶制造中更有效，而且所得到的材料也是完全新颖的。 由其制成的凝胶材料可以用于各种不同的最终用途，例如烹饪油过滤，柔软的皮肤清洁剂，牙科磨料等。 因此，本发明包括生产和使用方法，以及新颖的凝胶材料本身，特别是苛性碱和复合凝胶。

摘要： An environmental control for use in air handling systems that are required to provide highly effective filtration of noxious gases is provided. In one embodiment, a filtration system utilizes a novel combination of at least one metal-doped silica-based gel and zeolite materials to trap and/or modify, and remove such undesirable gases (such as ammonia, ethylene oxide, formaldehyde, and nitrous oxide, as examples) from an enclosed environment. The gel component exhibits specific porosity requirements and density measurements; the zeolite component is generally acidic and is preferably not reacted with any salts or like substances. The novel combination of such gels and zeolites permits highly effective noxious gas filtration over a wide range of known toxic industrial chemicals such that excellent breakthrough results are attained, particularly in comparison with prior media filtration products. Also included is the presence of an oxidizing agent on the gel materials to aid in capturing nitrogen dioxide and preventing conversion of such a product to NO. Methods of using and the application within specific filter apparatuses are also encompassed within this invention.

摘要： Disclosed is a fluid cosmetic composition comprising a sebum-absorbing calcium silicate. These cosmetic compositions provide effective, long-lasting facial cosmetic coverage that is highly resistant to the sebum-caused deterioration that results in the discoloration and fading typically experienced by conventional cosmetic compositions after a sustained period of use. The cosmetic composition may be in the form of a créme, lotion, gel, semi-solid, dispersion, suspension, foam, mousse or spray.
