Shaping Against Interior Of A Forming Surface By Rotation Of Material Or Material Shaping Member Patents (Class 264/503)
  • Patent number: 11000858
    Abstract: A centrifuge has a mechanical drive coupled to a capsule rotatable simultaneously about mutually orthogonal X, Y, and Z axes. A stationary base has a first motor driving a centrally located hub in rotation about the Z axis. The hub has a pair of colinear arms and a pair of struts extending from the arms to support an outer ring. An inner ring is positioned concentric with the outer ring and a second motor is engaged with both the outer ring and inner ring so that it is enabled for rotating the inner ring relative to the outer ring. A third motor is engaged with both the inner ring and the capsule for rotating said capsule relative to the inner ring. The simultaneous rotation of the capsule about all three axes is therefore possible.

  • Patent number: 10328614
    Abstract: A column or other elongate molded part is molded using an elongate tubular mold having a closed end, an open end and a flexible sidewall. After the column or other molded part is formed, it is extracted from the mold by pulling the column or other molded part axially through the open end of the mold. The column may be extracted using an expandable plug or gripper that is inserted into the interior of the column or other molded part through the open end of the mold. The expandable plug or gripper is expanded to engage an inner surface of the elongate molded part.

    Abstract: This invention includes malleable, biodegradable, fibrous compositions for application to a tissue site in order to promote or facilitate new tissue growth. One aspect of this invention is a fibrous component that provides unique mechanical and physical properties. The invention may be created by providing a vessel containing a slurry, said slurry comprising a plurality of natural or synthetic polymer fibers and at least one suspension fluid, wherein the polymer fibers are substantially evenly dispersed and randomly oriented throughout the volume of the suspension fluid; applying a force, e.g., centrifugal, to said vessel containing said slurry, whereupon said force serves to cause said polymer fibers to migrate through the suspension fluid and amass at a furthest extent of the vessel, forming a polymer material, with said polymer material comprising polymer fibers of sufficient length and sufficiently viscous, interlaced, or interlocked to retard dissociation of said polymer fibers.

    Abstract: The present invention provides a balloon having a non-uniform thickness that is adapted to facilitate folding of the balloon. The balloon comprises at least one relatively thin section formed between inner and outer surfaces of the balloon, and at least one relatively thick section formed between the inner and outer surfaces. The balloon may be formed from a balloon preform that similarly comprises at least one relatively thin section and at least one relatively thick section. The shape of the balloon preform may be formed, for example, by extrusion. The balloon preform may be placed in a balloon mold having a substantially cylindrical interior surface, and blow-molded to form the finished balloon configuration. The balloon comprises a non-uniform thickness, while comprising a substantially cylindrical outer diameter both after removal from the balloon mold and in an inflated state.

  • Publication number: 20100164147
    Abstract: A complex-shaped, three-dimensional fiber reinforced composite structure may be formed by using counteracting pressures applied to a structural lay-up of wetted fibers. The wetted fibers are arranged on pressurizable members and may be configured to include internal structural features, such as shear webs. A reinforcement stiffener may be located adjacent to at least one of the pressurizable members and the wetted fibers that form the internal structural feature. The reinforcement stiffener includes a modulus of elasticity that is substantially higher than a modulus of elasticity of the resin used to wet the fibers. In one embodiment, the reinforcement stiffener may be received in a pocket of one of the pressurizable members and may include a releasing agent that permits removal of the stiffener after the composite structure has been pressurized and cured.

    Abstract: The present invention provides a composite pressure vessel containing a distributor plate. The distributor plate comprises a thermoplastic polymeric disk having a top side, a bottom side, a perimeter edge and a central opening. The disk is provided with a plurality of radial slits, which define fluid flow passages through the disk between the central opening and the perimeter edge. The fluid flow passages through the disk are adapted to swirl fluid flowing through the disk from the bottom side to the top side such that it swirls around the central opening. The perimeter edge of the distributor plate is joined to an inner side of a thermoplastic liner during or immediately after the thermoplastic liner is formed by a blow-molding process or a rotational molding process.

  • Publication number: 20090319028
    Abstract: Tubular casting processes, such as dip-coating, may be used to form substrates from polymeric solutions which may be used to fabricate implantable devices such as stents. The polymeric substrates may have multiple layers which retain the inherent properties of their starting materials and which are sufficiently ductile to prevent brittle fracture. Parameters such as the number of times the mandrel is immersed, the duration of time of each immersion within the solution, as well as the delay time between each immersion or the drying or curing time between dips and withdrawal rates of the mandrel from the solution may each be controlled to result in the desired mechanical characteristics. Additional post-processing may also be utilized to further increase strength of the substrate or to alter its shape.

  • Publication number: 20090065980
    Abstract: The invention relates to a method and a device for blow-moulding containers from preforms which have been previously heated in a heating section and consist of a thermoplastic material. After being heated, said preforms are transferred to a blowing device in which they are deformed in order to form containers under the action of a blowing pressure inside blow moulds. The blow moulds respectively consist of at least two blow-moulding segments. The preforms are transported together with the blow moulds at least along part of a path of a rotating blow wheel. The blow-moulding segments are braced in relation to each other during at least part of the blow-moulding process. At least one of the blow-moulding segments is pivoted about a rotational axis in order to perform opening and closing movements.

  • Publication number: 20080224360
    Abstract: A method and device are provided for manufacturing a unitary caul sheet to be used in creating a composite material fuselage for an airplane. Specifically, a generally tubular shaped tool having a hollow interior cavity defining a fuselage IML surface is provided. In the method, a caul sheet material such as polyurea is applied to the IML surface before an armature is inserted into the interior cavity of the tool. Then, a filler material is introduced between the armature and the caul sheet material. Further, steam is injected to form the filler material into an infrastructure. Then, the caul sheet material is cured before the tool is removed from the caul sheet material to expose the caul sheet to receive composite material.
