Abstract:

A composition for dissolving and/or inhibiting deposition of scale on a surface of a system comprises an acidic component, a wetting agent, and a corrosion inhibitor. The composition may further comprise water. The acidic component comprises an alkanesulfonic acid, e. g. methanesulfonic acid (MSA). The wetting agent comprises a surfactant. The corrosion inhibitor comprises an amphoteric surfactant. The alkanesulfonic acid is present in an amount of at least about 50 weight percent (wt %), the surfactant is present in an amount of from about 0. 1 to about 30 wt %, and the amphoteric surfactant is present in an amount of from about 0. 025 to about 20 wt %, each based on 100 wt % of the alkanesulfonic acid, the surfactant, and the amphoteric surfactant combined. A method of dissolving and/or inhibiting deposition of scale on the surface of the system comprises the step of contacting the surface of the system with the composition.

Appl. No.:

11/480862

Inventors:

Stephen Gross - Dover NH, US

Assignee:

Lydall, Inc. - Manchester CT

International Classification:

D02G 3/00

US Classification:

428375000

Abstract:

A process is provided for producing improved, superior and more cost effective glass micro fibers, wherein molten glass in filament form is attenuated into glass micro fibers by gasses of a combusted mixture of air and fuel. The improvement comprises introducing into the mixture a gas stream containing at east 70% by volume of oxygen. This avoids problems in glass micro fiber production where the quality of the fibers varies from time to time, as demonstrated by the quality of paper produced therefrom. An apparatus for producing the fibers is also provided, as well as improved glass micro fibers and improved papers made therefrom.

US Classification:

210491, 210505, 210501, 977902

Abstract:

Disclosed is a media (such as a filter media) having one or more carbon nanotube (CNT)-containing layer. Each CNT-containing layer contains high temperature refractory fibers (e.g., staple quartz fibers and/or ceramic refractory fibers) that have melting temperatures greater than about 600 C. and in situ grown CNTs. Substantially all of the in situ grown CNTs have one end thereof associated with the fibers. This results in substantially all of the in situ grown CNTs extending away from substantially all of the fibers. Moreover, substantially all of the in situ grown CNTs are dispersed throughout the fibers. In one embodiment the media also includes one or more supporting layer. Each supporting layer contains high temperature refractory fibers that have melting temperatures greater than about 600 C., optionally bulk refractory fibers, optionally E-glass fibers, and optionally microglass fibers. The media can be tailored as a filter media to remove different size particles and have different dirt loading capacities depending upon the desire of the consumer.

C11D 3/00

Abstract:

Treatment compositions for use in laundry capable of providing sanitization through the wash e.g., for use with a detergent, where the compositions include an inorganic zinc salt potentiated by a phenolic solvent, to provide sanitization. The compositions can include an inorganic zinc salt, and a phenolic solvent, e.g., at an acidic pH (e.g., 2 to 5, or 3.5 to 4.5). The composition can include an anionic surfactant (e.g., alkyl sulfates, alkyl ether sulfates, etc.) and/or a nonionic surfactant (e.g., an alkyl polyglucoside). The composition may be free of alkoxylated nonionic surfactants which are not stable in the present compositions, which have high ionic strength (e.g., due to 3% of the zinc salt included in the formula). The composition may be free of various other components that would not be stable in such high ionic strength conditions, or otherwise interfere with stability and efficacy of the sanitizing and/or disinfecting laundry composition.
