  • Patent number: 5254190
    Abstract: A tendon for prestressed concrete structure comprises a core member such as a steel wire for prestressed concrete structures, a steel strand for prestressed concrete structures or a steel bar for prestressed concrete structures, and an unset bonding material coating the core structure in a predetermined thickness, having a specific setting time determined by selectively determining the respective contents of the ingredient of the bonding material and capable of setting at an ordinary temperature. The tendon is arranged in a desired arrangement for forming a prestressed concrete structure, concrete is placed so as to bury the tendons therein, and then the tendons are tensioned and fixed after the strength of the deposited concrete has increased to a degree to permit tensioning the tendons and before the unset bonding material sets. Thus, the unset bonding material sets after the tendons have been tensioned and fixed to bond the tendons firmly to the prestressed concrete structure.

  • Patent number: 5252160
    Abstract: A hybrid metal/composite spinner cone used in aircraft applications and a method of manufacturing the same. The spinner cone has a metal outer shell which is bonded during the molding process to an inner structural member of thermoplastic composite. The metal shell imparts several desirable characteristics to the spinner cone such as impact resistance, erosion resistance, appearance, and supplying a lightning strike material to protect the composite structure. The thermoplastic composite has significant property advantages over metal or thermoset systems. The hybrid metal/composite spinner cone is manufactured using a ceramic mold which is less expensive and more readily available than a steel mold. The metal shell provides a barrier between the thermoplastic composite and the ceramic mold and allows the finished spinner cone to be easily released from the mold.

  • Patent number: 5248356
    Abstract: A method for forming a seat belt through-bore in an automotive seat, which uses a lower die having an opening perforated therein and an upper die movable toward and away from the lower die, the method including the steps of providing a top cover member having an incision therein and two separate covering pieces sewn to a frontal surface of the top cover member such that they are disposed on the opposite sides of the incision, and turning upside down the thus-formed top cover member. In this method process, it is so arranged that, before lowering the upper die to press and bond the top cover member to a cushion member, the free portions of those two covering pieces are inserted into said opening of said lower die, so that the top cover member is placed flat upon the lower die, in order to avoid creation of undesired recession on the top cover member of resultant seat.

  • Patent number: 5246520
    Abstract: A continuous fiber reinforced composite panel and a one-step method of molding it using a high viscosity, thermoplastic matrix. The high viscosity, thermoplastic material is in the form of fibers and the fibers are commingled with reinforcing fibers producing a dry woven matte. The dry woven matte is placed in a mold and heated under pressure around a pin mandrel forming part of the mold. The method of forming the panels is a one-step method using a two-piece mold, one-half of which includes a pin mandrel having formed thereon a plurality of permanent die pins corresponding in number to the number of holes to be formed in the perforated composite panel. The other half of the mold has holes or cavities formed therein corresponding in number to the number of pins and into which these die pins are received when the mold is closed. The method simply is to place the dry woven matte over the die pins in the mold and to then close the mold. The mold is placed in a press and heat and pressure is applied to the mold.

  • Patent number: 5244522
    Abstract: A pair of hollow plastic tubes are welded together by mounting each tube in the clamp jaws of a holder in a bent condition to form the U-shape. A structural element is utilized to create a space between the bight of the U-shape and the holder. The bent tubes are disposed toward each other. A tube section separating member is moved into contact with the bent tubes and through the space between each bight and its holder to create a set of two tube sections from each bent tube. A tube section from one set is aligned with a tube section from the other set and the aligned sections are welded together. The structural element may be a weld seam resulting from a prior welding.

  • Patent number: 5244026
    Abstract: This invention relates to a combination of multiple tires disposed adjacently parallel to each other on a single wheel, respective inner spaces of the multiple tires being communicated with each other by way of an airflow piping. The airflow piping comprises a pneumatic pressure control valve which can be opened or closed due to an air-leaking condition of the multiple tires. When one of the multiple tires leaks air rapidly, the pneumatic pressure of the other normal tire is also decreased, thereby allowing the driver to notice the puncture. If the former leaks air slowly, its air is supplied by the latter, respective pneumatic pressures are going to become equal, thereby the driver can drive for a certain time and be free from any serious accident that may occur when he is unaware of the puncture.
