In some embodiments, a cylindrical smoking device made from a rectilinear sheet of flexible paper-like material. The sheet is die cut to form a taller portion and a shorter portion. The shorter portion is folded into an accordion shaped member. The longer portion is rolled around the accordion shaped member form in a cylindrical shape where the accordion shaped member is captured within the cylindrical shape. The cylindrical shape is retained by gluing the trailing edge of the taller portion to a location at the mid portion of the taller portion. The recess formed between the top of the cylindrical shape and the top of the accordion portion is capable of retaining a small amount of smoking material.

A fire-retarded cellulose fiber material composed of phosphoric acid and ammonium sulfate as fire-retardant chemical components, absorbed, adsorbed and/or adhered on the cellulose fibers, and optional non-fire retardant additives, and methods of producing the fire-retarded cellulose fiber material are disclosed.

The invention relates to a process for producing cellulosic shaped articles with stabilized inclusions in the form of a microfine dispersion of nonpolar organic compounds and mixtures by a dry-wet extrusion process. The shaped articles produced in this way exhibit by comparison with unmodified cellulose fibers a substantially increased storage capacity for nonpolar active substances. They are suitable in particular for use in textiles for clothing, industrial textiles, leisure, medicine and cosmetics. Potential functional effects imparted include the physical effect of heat storage and/or the uniform and finely meterable storage and release of nonpolar active substances and plant extracts from the interior of the fibers of the shaped articles. It is possible through a suitable choice of the nonpolar portion to produce by this process also fibers capable of absorbing liquid or gaseous nonpolar substances.

Methods for making fire retardant material including fire retardant cellulosic insulation are described. The methods include arrangements for partitioning fibers derived from fiber feedstocks and adding at least a portion of fibers of one or more feedstocks and a fire retardancy chemical compound to a mixer prior to fiber drying. The fibers may be disentangled and/or partitioned prior to mixing with the fire retardancy chemical compound. The fibers may be partially dewatered prior to the drying or other steps of the methods. The feedstock may include old newsprint (ONP), old corrugated containers (OCC), and/or other cellulose-based materials. The method further includes retaining the fibers feedstock and the chemical compound together for enough time to ensure adherence and impregnation of enough of the chemical to and in the fibers after the drying process. Fibers may be partitioned and disentangled prior to, during, and/or after treatment with the fire retardancy compound. The fire retardant cellulose insulation may be a standalone product or may be a component of a finished insulation end product.

An alternate resin-coated paper material for use in making honeycomb. The alternate resin-coated paper material is made from a paper that contains from 30 to 50 weight percent aramid fibers and from 50 to 70 weight percent of non-aramid fibers. A fire retarded phenolic resin is incorporated into the paper to make it self-extinguishing in less than 10 seconds with a self-extinguishing burn length of less than 12 inches when exposed to a 12-second vertical flame in accordance with the vertical burn test requirements set forth in 14 C.F.R. Part 25.583. The fire retarded phenolic resin includes a phenol formaldehyde resin and a phosphorous-containing fire retardant.
