Patent CA-2064071-A1 (CA)
IPC: A47L13/16
Filed: 1990-07-20
Abstract: 2064071 9101217 PCTABS00003 Unfused core forming fibers, indicated at (28), together with the facing sheet (24), are carried by the belt (20) into a thermobonder (22). The thermobonder (22) heats the fibers to a temperature above the melting point of at least one thermoplastic fiber material in the core. This heat fuses the core and also bonds the core to the facing sheet. At forming zone (54), the multilayered or composite web is typically bonded or densified along at least a section of the eventual peripheral edge margin of an article to be formed. Typically, the entire eventual peripheral edge margin of the article is densified. In addition, field bonds are also formed within the eventual field of the article intermediate the peripheral edge margin. The preferred approach is to emboss these bond areas. To this end, opposed sets of embossing rolls (70, 72, 74 and 76) are positioned as shown. The illustrated roll (70) comprises a field bond feature forming roll having a projecting pattern of field bond forming contacts (80) which press against the face sheet and other layers of the composite material.

Inventor: TROKHAN PAUL D
IPC: D03D1/00
Filed: 1991-06-14
Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by applying a coating of photosensi-tive resinous material to the reinforcing structure and pressing the reinforcing structure into a deformable surface, so that the de-formable surface forms protrusions which exclude resin from certain areas which when cured will lie along the backside of the belt, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has trans-parent and opaque regions. A process for making paper products is also disclosed which involves applying a fluid pressure dif-ferential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the em-bryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.

Title: Forming carbon dioxide in multi-phase molten bath
Inventor: NAGEL CHRISTOPHER J
IPC: C01B32/50
Filed: 1991-07-23
Abstract: A method and a system for converting carbon-containing feed to atomic carbon and for oxidizing atomic carbon to carbon dioxide is disclosed. Carbon-containing feed, such as municipal garbage, low grade fuel oil and organic or inorganic sludge is introduced to a molten metal bath. The molten metal bath includes a first molten metal phase having a significant solubility of atomic carbon and a second molten metal phase, substantially immiscible in the first molten metal phase and having a solubility of atomic carbon less than that of the first molten metal phase. Carbon in the carbon-containing feed is catalytically converted to atomic carbon.  The atomic carbon is oxidized in the first molten metal phase to carbon monoxide which is then directed to the second molten metal phase. Carbon monoxide in the second molten metal phase is oxidized to form carbon dioxide. The carbon dioxide is released to the atmosphere. Other atomic free radicals formed in the molten metal bath are substantially converted to oxides and other stable compounds.
