摘要:
Devices have a flexible housing with an inside chamber having a closed and open end. A first chemiluminescent fluid is disposed in a breakable container in the chamber, and a second chemiluminescent fluid is in the chamber. A tip assembly is attached to the housing and includes a nib movably disposed in the body, and a filter element may be positioned within the body to prevent passage of broken particles from the container to the nib tip. A resilient element is used to impose an outward biasing force on the nib. A porous material is disposed over an outer surface of the nib tip and securely held in place. The device is activated for use by bending the housing to break the container causing the first and second chemiluminescent fluids to mix and react, providing a chemiluminescent solution that flows to the tip assembly for dispensing onto a desired surface.

A writing instrument, which has an inner and outer writing element with separate writing medium reservoirs. The writing elements are coaxially mounted in an outer barrel and axially moveable with respect to one another. A driving mechanism may be actuated to allow a user to selectively extend one writing element. The inner and outer writing elements may have an inner sleeve therebetween to improve, for instance, rigidity of the outer writing element and to prevent contamination of the writing medium reservoirs. An outer sleeve may also be provided over the outer writing element. The outer sleeve can function to hold various components of the outer writing element together, and to allow for clean and easy refill of the outer writing element, especially when the outer writing element is a nib-type writing element with a filler-type reservoir. The writing instrument is designed so that a user can replace the inner and/or outer writing elements when their respective writing medium have been expended.
摘要:
A fountain pen and method of making the same in which liquid ink is fed from an ink container through a capillary section of a shape-maintaining writing tip which is characterized primarily in that the writing tip is formed by a thin-walled cap provided with ink from the inside while said cap has an end face in which a plurality of closely adjacent capillary openings or passages are provided.

A polyethylene powder has a molecular weight in the range of about 300,000 g/mol to about 2,000,000 g/mol as determined by ASTM-D 4020, an average particle size, D50, between about 300 and about 1500 μm, and a bulk density between about 0.25 and about 0.5 g/ml. On sintering, the polyethylene powder produces a porous article having a porosity of at least 45% and a pressure drop less than 5 mbar. The porous article is useful in, for example, wastewater aeration and capillary and filtration applications.
摘要:
A writing instrument comprising a tubular, ink-impermeable body portion containing a plurality of reservoirs that are housed adjacent to each other wherein each reservoir is separated from an adjacent reservoir by a reservoir barrier; a multi-sectioned nib disposed at one end of the writing instrument, said nib comprising a plurality of nib sections disposed adjacent to each other and separated from an adjacent nib section by a nib section barrier at a writing end, wherein the nib sections are secured adjacent to each other, and separated by said nib section barrier at one end thereof to form a writing end of the writing instrument, such that the nib sections do not communicate materials contained therein between adjacent nib sections, and wherein opposite ends of the nib section are spaced from each other and disposed within the tubular body portion such that each nib section is disposed in communication with a different reservoir.

A marker includes an enclosed housing with a marker tip of a marking element projecting from an open end of the housing. An aperture is formed through the marking tip, through which a wire may be journaled to mark the entire perimeter surface of the wire as the wire is pulled through the aperture.
