  • Patent number: 10293775
    Abstract: Airbag assemblies are disclosed that can reduce rotational velocity of an occupant's head during a collision event and thereby mitigate traumatic brain injury/head injury to an occupant. An airbag includes a pair of lobes or protrusions to deploy and extend from the rear face of the airbag on either side of the occupant's head to limit rotation of the head. A pair of vertical tethers within an interior of the airbag configure the lobes and contour the rear face to form one or more low fabric tension zones or bubbles. The lobes maintain high fabric tension, similar to a pressurization of a main inflatable chamber of the airbag.

  • Patent number: 9987814
    Abstract: The disclosure is directed to a method for co-molding. A first element has a top surface, an edge, and a protuberance with a base extending down from the top surface. A second element has an edge, an upper surface, and a lower surface. The mold includes a first mold portion defining a co-molding upper surface, and a second mold portion defining a co-molding mold cavity. The first element is placed into the second mold portion with the protuberance base in contact with the second mold portion. The second element is placed on top of the first element. The mold is closed, thereby producing the second element as a chamber. Fluid under pressure introduced into the chamber forces the second element to conform to the shape of the mold, thereby to affix the first element to the second element. Energy is applied to the mold to co-mold the elements together.

    Abstract: A process for forming a catheter balloon includes subjecting a tubular parison in a mold to molding fluid pressure. The resulting catheter balloon includes a balloon portion having two ends and tubular leg portions extending from either end. The ends of the balloon portion are tapered to the tubular leg portions. The tapered ends have alternating elongate areas of greater and lesser resistance to deformation displaced circumferentially about the tapered ends. The elongate areas of greater and lesser resistance to deformation can include ridges which are either longitudinal or spiraled or rods imbedded in the body of the balloon. While in the mold, the tubular legs are drawn axially sufficiently to form permanent creases in the tapered ends. This drawing may be sufficient to cause the material of the tapered ends to exceed the yield strength, particularly with the balloon material in a malleable state.

    Abstract: A catheter balloon and method involves extruded tubing with multiple layers of different durometer values, selected such that the blow up ratio (BUR) at the balloon's inner surface is increased. In one method a two stage blow mold process uses a small radius initial stage where radial growth is limited, followed by a second stage to a final dimension. A single stage blow mold process is also disclosed where the materials and processing are selected to approach the elongation to failure limit of the material. The single stage approach is preferably followed by a modified post-expansion heat set treatment to promote greater axial strength, leading to a preferred failure mode in the axial rather than radial direction.

  • Patent number: 8562898
    Abstract: A method for forming a resin molded article includes a step of extruding a thermoplastic resin intermittently at a predetermined speed from an extrusion slit, such that the resin droops downward in a shape of a sheet. The method further includes the steps of: feeding the extruded sheet-shaped resin downward by a pair of rollers; and forming the sheet-shaped resin with a mold. In the step of feeding the sheet-shaped resin, one of the rollers is pressed against the other, but not to the extent of crushing the sheet-shaped resin, regardless of the thickness of the sheet-shaped resin. In addition, a surface temperature of each of the rollers is set lower than a temperature of the sheet-shaped resin and within a predetermined temperature range. This method can prevent sliding contact between the rollers and the sheet, while preventing the sheet from being wound around the rollers.

  • Patent number: 8524340
    Abstract: The preform of the biaxially drawn, blow-molded bottle comprises polyethylene terephthalate layers 2 and at least a gas barrier layer 3 laminated with the polyethylene terephthalate layers. The gas barrier layer 3 extends downward from a level halfway to the height of the neck 4 including the neck ring 5, or at least from above the neck ring 5, down virtually to the lower end of body 6. The gas barrier layer 3 inside the wall of the neck 4 has an average thickness corresponding to a third (?) or less of the maximum thickness of the gas barrier layer 3 inside the wall of the body 6, allowing most of the gas barrier material to be located in the wall of the body 6. Thus, the gas barrier material is effectively utilized, and in the case of the heat-resistant bottle, the neck has the predetermined dimensions without fail after the whitening treatment.

  • Patent number: 8449800
    Abstract: A preventative maintenance method of strengthening the connection between high pressure, in situ piping. An encapsulation mold is installed over a properly functioning, non-leaking coupling or joint interconnecting pipe sections carrying gas in excess of 60 psi. A resin sealant having tensile strength in excess of 3000 psi fills the mold, so that it circumscribes the coupling and adjacent portions of the pipe sections extending from the coupling, forming a permanent bond to the coupling and pipe sections. The method prevents high pressure pipe connection pullout, which otherwise could lead to catastrophic failure.

  • Patent number: 8404755
    Abstract: Polyester compositions described herein have properties which are particularly suitable for extrusion blow molding (EBM). These properties relate primarily to the rate of crystallization and melt strength or melt viscosity. Articles prepared from the polyester compositions exhibit good clarity, aesthetics, and other physical properties. The polyester compositions also exhibit broad molecular weight distribution (MWD), resulting in improved processability and melt strength. The crystallization rate allows for good drying characteristics while also enabling the use of regrind. In addition, the compositions exhibit improved recyclability, such as in existing PET recycling streams. In one aspect, articles are prepared in an extrusion blow molding method by combining a dry first polyester copolymer component, a dry second polyester component, and a chain extender to form a feed material suitable for extrusion blow molding.

  • Patent number: 8388020
    Abstract: Described is an inflatable multilayer bolster for a vehicle passenger compartment including a hollow body with back and front walls, an air chamber formed between them, and an inflator for injecting pressurized fluid to inflate the hollow body. Preferably, both the front and back walls have an inner layer made of a structural deformable material and an outer surfacing layer co-extruded with the inner layer. Also described is a method of manufacturing the multilayer bolster by co-extruding first and second polymers through a die to produce a parison, and then blow-molding the parison to form the hollow body. Thus the front wall and preferably the back wall as well have an inner layer made of the first polymer in a structural deformable condition and an outer surfacing layer made of the second polymer. This co-extruded multilayer constructed bolster allows efficient manufacturing, structural, inflation and aesthetic characteristics.
