摘要:
A nonwoven fabric composite that comprises at least one extensible layer of elastomeric fine fibers treated with a wetting agent is provided. The nonwoven fabric composite can be used a barrier layer or a wrap for an absorbent materials to prevent particles form migrating out of the absorbent material.

The present invention is a laminate article comprising at least three layers of plasticized polyvinylbutyral (PVB) sheet, wherein at least one layer of the laminate is a stiff PVB sheet and at least two layers are soft PVB sheets. A laminate article of the present invention is useful for providing increased protection from damages occurring to automobiles, buildings, and windows by virtue of exposure of same to, for example, hurricane force winds, impact from debris propelled by high-force winds, or by intentional impact against windows comprising the laminates of the present invention.

Techniques for processing calls in a communications system. A method and a system for protecting a person's telecommunications identify includes associating a global phone number with at least one contact address. The person may publicize global number. Thereafter, the person receives all communications using the global number. Using global number, the disclosed subject matter confidentially transfers the communications from global number to at least one direct contact address. The method and system may further include screening out undesirable communications.
摘要:
A trailing arm has a first side portion with an axle recess and a second side portion with an axle recess. An upper portion of the trailing arm is defined at least partially by overlapping portions of the first side portion and the second side portion. The overlapping portions define a weld aperture in the upper portion and a suspension aperture.
摘要:
Solid phosphoric acid (SPA) olefin oligomerization process units may be converted to operation with a more environmentally favorable solid catalyst. The SPA units in which a light olefin feed is oligomerized to form gasoline boiling range hydrocarbon product, is converted unit to operation with a molecular sieve based olefin oligomerization catalyst comprising an MWW zeolite material. Besides being more environmentally favorable in use, the MWW based zeolites offer advantages in catalyst cycle life, selectivity. After loading of the catalyst, the converted unit is operated as a fixed-bed unit by passing a C2- C4 olefinic feed and a light aromatic co-feed containing benzene to a fixed bed of the MWW zeolite catalyst to effect alkylation of the benzene with the aromatic co-feed, typically at a temperature from 150 to 350° C., a pressure not greater than 7000 kpa, usually less than 4000 kPa and an olefin space velocity up to 10 WHSV.
摘要:
The present invention is an improved polymeric resin composition comprising or consisting essentially of from about 70 wt % to about 79 wt % units derived from ethylene and from about 21 wt % to about 30 wt % units derived from an α,β-unsaturated carboxylic acid having from 3 to 8 carbons. Resins of the present invention are particularly suitable for preparing transparent laminates useful as glazing elements that provide a greater measure of safety than non-laminated glazing elements. Laminates of the present invention have 3% haze or less without the addition of amines.
