Abstract: A molded product consisting of a skin layer and a core layer is obtained by injecting a skin layer resin and a core layer resin from a skin injection unit 13 and a core injection unit 12 into metal molds 8, 9, respectively. The skin layer resin injection pressure by the skin injection unit 13 and the core layer resin injection pressure by the core injection unit 12 are controlled in such a manner that a volumetrically reduced quantity at the time of cooling and solidifying the skin layer resin is compensated so as not to generate defects such as hollows and the like in the molded product. It is characterized in that the state the core dwelling pressure is higher than the skin dwelling pressure over a predetermined length of time.

Abstract: A prestressed concrete casting apparatus includes a prestressing element (e.g., wire cable or rod) pretensioning fixture of simple easy to use construction, and great strength/rigidity for withstanding considerable pretensioning forces. Advantageously, a clamshell-type mold form may be used together with the pretensioning fixture, in such a manner that the mold form is easily properly locatable on the pretensioning fixture. The form can be removed for reuse without moving the pretensioning fixture or otherwise disturbing the casting, which is permitted to continue to cure in the stationary pretensioning fixture. Maintaining the pretensioning fixture stationary during the process lends greater structural integrity and stability to the pretensioning fixture under the considerable forces set-up by the pretensioning of the prestressing elements.

Abstract: Tire rubber material is highly accurately and efficiently extruded by a positive displacement extruding system that includes, as seen from an upstream side of the tire rubber, a screw extruder unit, a gear pump unit and an extrusion head unit with an extrusion nozzle, which are connected in series with each other. While the tire rubber is caused to flow through the extruding system, the temperature of the rubber material is measured and controlled to be within a predetermined temperature range, in accordance with the measured temperature of the rubber material. The rubber material maintained at a controlled temperature is extruded from the extrusion nozzle, thereby improving the positive displacement performance of the extruding system.

Abstract: A slush hydrogen production device (10) utilizes a hydrogen slushifier magnetic refrigerator (30) having a wheel (50) of material exhibiting the magnetocaloric effect. The wheel is rotated through a magnetic field of varying intensity around the circumference of a wheel housing (36) created by the windings of superconductive magnets (56). The material of the wheel (50) follows a magnetic Carnot cycle as the wheel rotates (36) through regions of low temperature heat transfer and high temperature heat transfer. Liquid hydrogen is supplied to the regions of low and high temperature heat transfer through inlet pipes (39 and 42). Gaseous hydrogen is produced in the high temperature heat transfer region and vented away by an outlet pipe (48). Solid hydrogen is produced in the low temperature heat transfer region by direct solidification upon the magnetic wheel (50); and is removed by scrapers (76) and deposited in a compartment (26) where it mixes with liquid hydrogen to form slush hydrogen.

Abstract: The present invention relates to a process for making polymer tapes utilizing metallocene catalysts. An isotactic propylene polymer is prepared by polymerizing propylene in the presence of an isospecific metallocene catalyst. The resulting polypropylene is heated, extruded and withdrawn as a sheet. The sheet is then slit longitudinally into tape segments and drawn in the longitudinal direction to a draw ratio of at least about 4.5:1 to produce an oriented tape. It has been found that these polypropylene tapes have different characteristics than those polypropylene tapes produced using Ziegler-Natta catalyst drawn at the same draw ratios.

Abstract: A rubber hose having a multilayer wall is formed of an inner layer of NBR type rubber having a high AN content, available at a low cost and highly impermeable to fuel and an outer layer of a rubber composition having a minimum Mooney viscosity of 25 to 65 at its curing temperature and highly resistant to flattening. Those layers are extruded and cured together without the aid of any mandrel owing to the inside diameter and wall thickness of the hose and the thickness of the outer layer which fall within specific ranges. This process enables the manufacture of a fuel hose having a high fuel impermeability at a low cost, while protecting its inner wall effectively from flattening during curing.

A loosely felted mat of wood flakes is placed between top and bottom molds which slidably engage one another at pinch points to pinch and sometimes remove excess flashing/pinch trim.

Abstract: The present invention provides a method for manufacturing a non-gelatin hard capsule shell. The hard capsule shell is made by a heat-melting method which involves heating a capsule forming composition (preferably in powdery form) in a mold, followed by inserting a pestle into the mold to coat the melted capsule forming composition onto the pestle. The hard capsule shell thus formed, after hardened and dried, is removed from the pestle. This method has the advantages over the conventional “dip molding method” for not requiring the capsule forming composition to be pre-dissolved in solution so that no solvent is used in preparing the capsule forming composition. Also, by inserting a pestle into a mold, a pressure is imposed so as to ensure uniform coating of the capsule forming composition to the pestle. The present invention also provides a capsule forming composition which comprises a polymer and optionally a plasticizer and an apparatus for making the non-gelatin hard capsule shell.
