IPC: B27N7/00
Filed: 1999-03-22
Abstract: A mat of bulk material including intermingled wood chips or other fiber material and a binder is consolidated and pressed in a hot press to form a panel initially having smooth surfaces. A cure retarding agent or a slower-curing binder is applied to or mixed into an upper layer of the bulk material mat so as to retard the curing of the binder in this upper layer, so that the upper surface of the panel exiting the hot press is not yet fully cured and remains soft. Alternatively, a softening agent is applied onto the upper surface of the substantially fully cured and hardened panel exiting from the hot press, to re-soften the upper surface of the panel. Then a roughness or texture is embossed into the soft upper surface of the panel, followed by complete curing and hardening of the roughened or texturized surface. An apparatus to carry out the method includes bulk material spreaders, a conveyor, a hot press with smooth press bands or platens, a cure retarding agent or softening agent application device, and a texture embossing device.

Title: Absorbent articles having lotioned leg cuffs
Inventor: SCHULTE THOMAS EDWARD
IPC: A61Q19/00
Filed: 1997-12-03
Abstract: An absorbent article, such as a diaper, containing leg cuffs coated with a lotion composition is disclosed. The lotions disclosed in the present invention minimize the abrasion between the cuffs and skin in the area where the cuffs contact the wearer's skin, resulting in less skin irritation. The lotion compositions also reduce the adherence of BM to the skin of the wearer, thereby improving the ease of BM clean up. The lotion composition comprises a plastic or fluid emollient such as mineral oil or petrolatum, an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the emollient on the surface of the diaper leg cuffs, and optionally a hydrophilic surfactant to improve the processability and/or stability of the lotion compositions.  Because the emollient is substantially immobilized on the surface of the leg cuff, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.

Filed: 1997-12-12
Abstract: A process of crystallizing CL-20 is disclosed. In the process, a wet CL-20 solvent/CL-20 solution is dried by azeotropic distillation of a CL-20 solvent/water azeotrope. Removal of water from the CL-20 solution permits crystallization of high density CL-20. A low density, CL-20 non-solvent is added to the resulting dry CL-20 solvent/CL-20 solution to cause precipitation of .epsilon.-polymorph CL-20. The CL-20 crystals are separated from the non-solvent and the solvent by adding sufficient water to displace the non-solvent and the solvent from the surface of the CL-20 crystals. In this fashion, the .epsilon.-polymorph CL-20 is made wet for later handling, packaging, and shipping.

Title: Backfill paste production facility and method and apparatus for producing high density slurry and paste backfills
Inventor: CHEN LONG JIN
IPC: B28C9/00
Filed: 1998-01-23
Abstract: The invention relates to a method and apparatus for producing high density slurry and paste backfills for use in mining operations and to associated backfill paste production facilities which incorporate the aforesaid method and apparatus. The high density slurry or paste is produced from a mill tailings mixture in a silo (11) which includes a percolation/decant device (12) for percolating water out of the mill tailings mixture and for decanting clarified water (64) from atop the settled tailings (66). While settling occurs, air is introduced from the bottom (13) of the silo (11) to agitate the mixture to ensure substantially homogeneous settlement of the solids. Once settled, the resultant high density slurry or paste is fluidized by air in order to give the paste more readily flowable characteristics. The flowable paste can then be mixed with a setting agent and pumped or transported to the mine site to be used as a settable backfill.

Title: Benzene conversion in an improved gasoline upgrading process
Inventor: HILBERT TIMOTHY L
IPC: C10G29/20
Filed: 1998-05-12
Abstract: Low sulfur gasoline is produced from an olefinic, cracked, sulfur-containing naphtha by treatment over an acidic catalyst, preferably an intermediate pore size zeolite such as ZSM-5 to crack low octane paraffins and olefins under mild conditions with limited aromatization of olefins and naphthenes. A benzene-rich co-feed is co-processed with the naphtha to reduce the benzene levels in teh co-feed by alkylation. This initial processing step is followed by hydrodesulfurization over a hydrotreating catalyst such as CoMo on alumina. In addition to reducing benzene levels in the combined feeds, the initial treatment over the acidic catalyst removes the olefins which would otherwise be saturated in the hydrodesulfurization, consuming hydrogen and lowering product octane, and converts them to compounds which make a positive contribution to octave. Overall liquid yield is high, typically at least 90 % or higher. Product aromatics are typically increased by no more than 25 wt.% relative to the combined feeds and may be lower than the feed.
