Inventors:

Thomas Scanlan - Woodbury MN, US

International Classification:

B01D 35/28

US Classification:

210445000, 210455000, 210450000

Abstract:

There is provided a liquid filter comprising a filter vessel having a removable cover, a fluid inlet, an engagement lip for a filter and a fluid outlet, an open top, fluid impermeable sidewalls, and a fluid outlet at a bottom of the insert. Into the filter vessel is inserted a water impermeable insert having an insert lip engageable in a sealing relationship with the filter vessel engagement lip. A single cartridge filter is inserted within the cartridge filter insert having a generally solid top surface, a bottom fluid outlet sealingly engageable with the insert outlet and a filter material. The cartridge filter top surface forms a weir for diverting fluid to be filtered toward an annular opening created between the filter cartridge and the insert, the annular opening having a cross sectional area, which generally is from 25 to 100% of the cross sectional area of the filter cartridge outlet opening.

International Classification:

E04B 208

US Classification:

525861

Abstract:

Enclosure 1 constructed of panels 20 which can be joined by tongue and groove or press fit spline 46 and groove 26 technique. Acoustic shielding is achieved by properly selected materials of construction, e. g. syntactic, cellular composites. The doorway 10 of the enclosure is closed by a door 210 penetrated only by a guide 175. The latch mechanism 170 and 340 seals the door against the door jamb 185 by means of cam rollers 316 which engage indentations 189 (which may have specialized cam surfaces or inclined surfaces) along the door frame. The latch mechanism can be actuated from either side of the door by mechanical means engaging the guide.

International Classification:

B32B 326
E04B 182

US Classification:

4283044

Abstract:

A method of using a material as an acoustical barrier in an ambient medium. The material comprises microbubbles having average outer diameters of 5 to 150 microns, bound together at their contact points. The material is characterized by either a porosity of 20 to 60 percent, or by voids between the microbubbles which have characteristic diameter within an order of magnitude of the viscous skin depth of the ambient medium, as calculated at 1 kHz; an air flow resistivity of 0. 5. times. 10. sup. 4 to 4. times. 10. sup. 7 mks rayls/meter, and an attenuation of sound comparable to mass law performance. The microbubbles can be sintered into direct contact with each other, or one of many types of binder material can be used to support the microbubbles within a composite material. The method may be practiced in an acoustical system comprising a sound source and the material, such as by placing a muffler comprising the material substantially in a direct path of a fluid; and also in applications requiring high specific stiffness and flexural strength.

US Classification:

Abstract:

Hydrated sodium silicate particles can be expanded by heat to form thin-walled bubbles that can be broken, neutralized, washed and dried to provide hydrated silica flakes. These flakes can be mixed with non-swelling sorptive particles such as TLC grade silica and used to make chromatographic articles. One such article is a composite of a poly(tetrafluoroethylene) fibril matrix in which those particles and hydrated or fired silica flakes are enmeshed. The hydrated silica flakes can be fired to a refractory state and then incorporated into protective coatings to enhance their resistance to abrasion while also better protecting the coated substrates from corrosion.
