Abstract:
The disclosure relates to a method of coating an intramedullary (IM) nail with flowable material, comprising: advancing the IM nail into a tubular member from an insertion end of the tubular member toward an opposite end of the tubular member; advancing flowable material through a first port defined through a sidewall at a first location on the tubular member; advancing flowable material through a second port defined through the sidewall at a second location, distinct from the first location, on the tubular member; and subsequent to curing of the flowable material, removing the tubular member from the IM nail having the cured flowable material thereon.
Abstract:
Examples of forming metal composites are described herein. In an example, a metal sheet is formed into a predetermined shape using superplastic thermal forming technique. Further, a carbon fiber-reinforced polymer sheet is shaped into the predetermined shape by thermal forming. The metal sheet and the carbon fiber-reinforced polymer sheet are coupled by applying an adhesive between the metal sheet and the carbon fiber-reinforced polymer sheet, to form a metal composite.
Abstract:
A removable, magnetically-affixed mechanical wear element, preferably comprising ultra-high molecular weight polyethylene or polyurethane materials, is provided for affixation to a ferrous substrate material. The mechanical wear element is configured so that the magnetic attachment element is not easily removed or dislodged from the mechanical wear element, without regard to choice of mechanical wear element material utilized.
Abstract:
The invention relates to a pressure-medium unit, comprising a housing (2, 4), which is produced by injection molding and composed of plastic, in the housing wall (36) of which housing at least one connection bush (26, 28) having a passage opening (32) is fastened, through which pressure medium is fed into and/or led out of the interior (16) of the housing (2, 4). According to the invention, in the injection molding process of the housing (2, 4), the connection bush (26, 28), with the exception of the passage opening (32), is at least partially injection-molded into the housing wall (36).
Abstract:
The present disclosure is directed to a root assembly 30 for a rotor blade 16 of a wind turbine 10 and methods of manufacturing same. The root assembly 30 includes a blade root section 32 having an inner sidewall surface 40 and an outer sidewall surface 42 separated by a radial gap 44, a plurality of root inserts 46 spaced circumferentially within the radial gap 44, and a plurality of spacers 52 configured between one or more of the root inserts 46. Further, each of the root inserts 46 includes at least one bushing 48 surrounded by a pre-cured or pre-consolidated composite material 50, 54. In addition, the spacers 52 are constructed of a pre-cured or pre-consolidated composite material 50, 54.
Abstract:
The present invention provides a method of producing a metallized polymer-electrode composite comprising transferring a conductive metal foil from a metal transfer film to a surface of a polymer film The inventive method may be used to produce a polymer film with optionally textured, conductive metal electrodes on one or both sides. The method of Hie invention may find utility in producing electroactive polymer transducers and other thin film devices requiring flexibility or stretchability such as thin film batteries, sensors, speakers, reflective plastic displays, solar cells, and supercapacitors.
Abstract:
An elastomeric seal (20), such as a shaft seal for automotive vehicle applications, includes an elastomeric compound (22) chemically coupled to a metal sealing ring (24) and is formed without an oven post curing step. The elastomeric seal (20) provides exceptional physical properties, similar to those of elastomeric seals of the prior art formed with an oven post curing step. The elastomeric seal (20) has an elastic modulus of 6.0 MPa to 13.0 MPa and a tensile strength of 11.1 MPa to 14.8 MPa. The elastomeric compound (22) includes 52.0 to 68.0 wt. % fluoroelastomer, 20.0 to 35.0 wt. % calcium silicate, and 5.0 to 15.0 wt. % diatomite. The elastomeric compound (22) is fully cured and chemically coupled to the metal sealing ring (24) during the compression or injection molding step, and thus an oven post curing step is not required.
Abstract:
The disclosure is directed to a method for producing a Fiber Metal Laminate component of an airplane, using a manipulator system with an end effector and a control, wherein at least one metal layer and at least one unhardened fiber layer are being stacked onto each other in a mould in a stacking sequence, wherein each stacking cycle comprises picking up a metal layer or a fiber layer from a supply stack according to the stacking sequence, transporting the layer to the mould, placement of the layer at a deposition surface in the mould and depositing the so placed layer onto the deposition surface. After being picked up from the supply stack and before being deposited onto the deposition surface the layer to be stacked can be deformed by the end effector as to adapt the form of the layer to the form of the deposition surface.
