摘要： A method to produce thin-layer lignocellulosic composites, such as wood-based doorskins, that exhibit substantial resistance to moisture is disclosed. In an embodiment, the method includes the steps of forming a mixture including a refined lignocellulosic fiber, wax, and an organic isocyanate resin. The mixture is initially pressed to form a loose mat. Subsequently, the mat is pressed between two dies at an elevated temperature and pressure to further reduce the thickness of the mat and to promote the interaction of the resin with the lignocellulosic fibers. In an embodiment, a release agent is included as part of the fiber mixture, or sprayed onto the surface of the mat. The thin-layer lignocellulosic composites of the present invention exhibit strong surface strength, high adhesiveness, and a 50% reduction in linear expansion and thickness swelling upon exposure to a high moisture environment as compared to thin-layer composites that do not include the isocyanate resin.

摘要： System for protecting machine parts, such as threads, from physical and chemical damage. The parts to be protected are cleaned, coated with a separating agent, and a mold is placed around them. A protective material is inserted in the interspace between the mold and pipe end. The protective material forms a tough, protective jacket. If desired, the jacket can later be removed by means of a tear-open element or integrated weak spots. For the protection of pipe interiors, plastic material can be pressed into the end of the pipe such that it seals against the inside lining of the pipe.

摘要： Method for making a wheel composed of a rigid plastic inner section forming the wheel hub and rim and a resilient plastic tire section encircling the rim. A key formed integrally with the rim extends radially outward therefrom and interlockingly projects into the tire so as to mechanically connect the tire to the rim all around the wheel. The key can be formed with axially extending portions spaced radially outboard of the rim and terminating flush with the outer surface of the tire section so as to provide colored side wall decorations at one or both sides of the wheel. A method of molding the tire directly onto the discoid section is also disclosed.

摘要： A layer of an ion exchanged glass is utilized as the master for video disc production. Due to the ion exchange, such glass possesses stored energy in the form of compressive stress. When localized portions of the layer of ion exchanged glass are heated sufficiently, those portions of the glass soften and release the compressive stress energy in the form of localized surface bumps. The presence or absence of surface bumps and/or their height can convey the video information in analog or binary form. Once the ion exchanged master is formed, the master is used in a conventional manner to produce mirror image copies on a suitable, conventional substrate, generally a plastic. The copies are generally formed by a pressing or stamping technique, or by an injection molding technique. The relief surface of the copies can be coated with a conventional light reflective layer to aid in optical read-out of the video information stored by the relief surface.

摘要： A four-sided turret interposed between a fixed and a movable platen of an injection-molding machine, mounted on a carriage which is slidable in the direction of platen motion, is rotatable about an axis perpendicular to that direction into four operative positions spaced 90.degree. apart. In each of these positions, in which one or more cores carried on one of its faces enter respective cavities of a confronting mold plate on the fixed platen while a corresponding core or cores on an opposite face are received in a companion plate on the movable platen, the turret is positively indexed by two aligned pins on these plates which enter respective bores in the turret upon closure of the mold; such closure, conversely, is prevented by the pins until the turret is in the proper position. The core or cores on each turret face may traverse a respective stripper plate overlying that face or may be penetrated by ejector pins carried on a relatively movable holding plate; after a workpiece molded around a core of any such face has been rotated through three turret positions, rollers linked with the associated stripper or holding plate are engaged by a pair of cam bars on the two platen-associated plates during a mold-closing stroke to dislodge the molded workpiece from its core.
