    摘要: The use of acrylate or methacrylate esters of polyalkylene oxide derivatives of alkyl/aryl phenols as wetting agents and adhesion promoters in ultraviolet curable systems is disclosed. These materials may be added to the ultraviolet system in a quantity between about 5 and 50 weight percent, based on the total weight of the ultraviolet curable composition.

    摘要: A novel, high performance yet permeable, tough, fibrous structure, and a process for making the structure are disclosed. The fibrous structure includes a stabilized microstructure of improved uniformity of fiber and particulate distribution. Beneficially, the fibrous structure is of improved structural integrity and stiffness, as a result of being reduced in thickness. The process includes the steps of dry forming a fibrous web including crimped staple composite fibers, thereafter distributing and entrapping the functional particles in the web, and thereafter heating the fibrous web to form a microstructure-stabilized fibrous web. According to the process, the microstructure-stabilized fibrous web is thereafter by an additional heat treating step carried out without application of pressure to the web, heated to a thermoforming temperature, and thereafter the heated web is reduced in thickness and yet microstructural relative geometry is maintained. IR heat may be used. A nip gap is advantageously used to reduce the heated web in thickness.

    摘要: A device is provided for testing a pressure drop across a cigarette filter rod. The device includes an expansible sleeve for encapsulating a filter rod and a two stage vacuum pump connected thereto. A first controllable valve connects the outer surface of the sleeve to the vacuum pump to expand the sleeve so that a filter rod can be inserted. The first controllable valve also connects the end of the sleeve to the vacuum pump so that a measurable pressure drop is created across the filter rod. A second controllable valve is connected between an exhaust port of the vacuum pump and the end of the sleeve so that, after the testing has been completed, the filter rod will be ejected from the sleeve. The pressure testing device is thus self contained and does not require an external source of vacuum or compressed air.
