    摘要： A temporary plug for stemming the flow of water in a water system during the repair of a pipe. The plug is constructed of a water soluble fiber, preferably poly(vinyl alcohol) polymer fiber. The polyvinyl alcohol fiber is preferable carded and needle punched into a fibrous sheet material. Plugs of a predetermined size are then cut from the fibrous sheet material.

    摘要： A device and method for supporting a meltable tart and removing hot molten wax or other material from the tart when heated. The device has a heat resistant body formed of a material that is of sufficient porosity to absorb or soak up hot molten wax or other material from the tart and to retain its structural integrity so that it can be disposed of after it has absorbed or soaked up the hot molten wax or other material from the used tart.

    摘要： An enhanced filtering media composite formed of a first electret media layer attached uniformly onto a second non-woven fibrous media layer by a special needling construction and procedure, so as to provide a needled media composite having increased mechanical strength and particle retention capacity. The first media electret layer is composed of about 50 wt. % mixture of polypropylene and modacrylic fibers, and the second media layer is composed of 80% 3 denier.times.3 inch polyester staple and 1.4 denier.times.1.5 inch polyester staple fibers, the fibers of one layer being selectively needled into the other layer using controlled needling density penetration, depth and repetitions to provide a composite having improved mechanical strength and filtration performance.
