  • Patent number: 10786953
    Abstract: A method of manufacturing a composite part having a curved or radiused corner to avoid wrinkling or bridging of outer-most composite plies during consolidation and cure, including laying up composite material on male or female tooling to form two flanges extending at a first angle relative each other and a curved or radiused corner extending between the two flanges. Then the method may include changing an orientation of one or both of the flanges of the composite material, such that the two flanges extend at a second included angle relative each other. The second included angle is smaller than the first angle. The method may also include a step of consolidating the composite material before, after, or during the step of changing the orientation of the composite material to the second angle, as well as a step of curing the composite material oriented at the second angle.

  • Patent number: 10780684
    Abstract: A bonding device includes a flexible platen disposed between an upper platen assembly (9) and a transmission device and within a vacuum chamber (6). The flexible platen can expand to apply a downward pressure to the upper platen assembly (9) connected thereto. Under the effect of the pressure, the upper platen assembly (9) slowly moves downward until the upper platen assembly (9) itself and a lower platen assembly (7) respectively come into tight contact with objects to be bonded. After that, the flexible platen continues exerting the downward pressure on the upper platen assembly (9). In this way, the pressure applied by the upper platen assembly (9) to the objects to be bonded is uniform. Meanwhile, because of slow expansion of the flexible platen, the uniform pressure is applied slowly by the upper platen assembly (9).

  • Patent number: 10780644
    Abstract: A method for joining two objects by anchoring an insert portion provided on a first object in an opening provided on a second object. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. During the step of inserting the insert portion in the opening and/or during anchorage a clamping force is applied to opposing surfaces of the second object to prevent the second object from cracking or bulging.

  • Patent number: 10751935
    Abstract: The automation of the assembly of a stack of substrates in the process of forming an object includes a blanking die having a push through plate to drive the blanked sheets onto a set of locating pins, thereby creating a very accurate stack. An image forming device may print and develop images onto a web that is subsequently die cut and stacked onto a curing platen. The die cutter cuts individual sheets out of the web and cuts or pre-cuts alignment holes into each sheet that would be accepted by the curing platen having locating pins corresponding to the alignment holes in the sheet. The die cutting operation includes a tamping device that would accurately transfer the sheets from the die to the curing platen. This stack may then be removed and/or processed to form a 3D object.

  • Patent number: 10737438
    Abstract: A method of forming a three-dimensional object is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween, with the carrier positioned adjacent and spaced apart from the build surface at a start position; then (b) forming an adhesion segment of the three-dimensional object (c) optionally but preferably forming a transition segment of the three dimensional object; and then (d) forming a body segment of the three dimensional object. In each case, the segment can be formed by: (i) filling the build region with a polymerizable liquid, (ii) continuously or intermittently irradiating the build region with light through the optically transparent, and (iii) continuously or intermittently advancing the carrier away from the build surface, to thereby form that segment from the polymerizable liquid.

  • Patent number: 10716622
    Abstract: The present disclosure relates generally to medical devices, and more specifically to ablation catheters including bond joints formed to have improved strength and resistance to failure during use. In many embodiments an expanded bond-joint length and area and gap filling are used to increase the strength of the bond joint while decreasing relative variability. The bond joint length area is increased in a controlled manner so as to increase the overall strength of the bond joint by shifting the failure mode from the bond joint to a stronger area of the ablation catheter, such as the catheter shaft. Related methods of manufacturing such ablation catheters (or other medical devices including a bond joint) are also disclosed and described herein.

  • Patent number: 10716919
    Abstract: A delivery sheath includes an outer tubular layer and an initially folded inner tubular layer. When an implant passes therethrough, the outer tubular layer expands and the inner tubular layer unfolds into an expanded lumen diameter. The sheath may also include selectively placed longitudinal support rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion, thereby reducing the push force needed to advance the implant through the sheath's lumen.
