  • Patent number: 11726121
    Abstract: An automated resonant waveguide cavity system for determining one or complex permittivity measurements of a sample is provided. The automated resonant waveguide cavity system includes a resonant cavity, a waveguide coupled to the resonant cavity, a programmable network analyzer (PNA) coupled to the waveguide, and a computing device. The computing device includes a memory storing processor executable code for a determination engine and a processor executing the processor executable code to cause the determination engine to obtain data from the PNA. The data is respective to the sample within the resonant cavity.

  • Publication number: 20230234270
    Abstract: In one aspect there is disclosed a method of improving shot repeatability in a multilayer reciprocating screw injection molding apparatus by preventing pressure communication or “cross-talk” between melt channels. In the first aspect an outlet nozzle valve is closed prior to closing a check valve within an injection unit of the multilayer reciprocating screw injection molding apparatus. In another aspect there is disclosed a method of improving shot repeatability in a reciprocating screw injection molding apparatus by recording a first position of a screw within the barrel of an injection unit of a reciprocating screw injection molding apparatus, the first position corresponding to a volume of melt within the barrel of the material injection unit. A second position of the screw is then calculated based on the first position, the second position corresponding to a transition position of the screw within the barrel of the injection unit of the reciprocating screw injection molding apparatus.

  • Publication number: 20220402186
    Abstract: In one aspect, a method of molding a multilayer article comprises causing a surface layer material injection unit to commence injecting a surface layer material into a mold cavity via a surface layer material channel. Then, an internal layer material injection unit commences injecting an internal layer material into the mold cavity an internal layer material channel. Then, during application of a hold pressure upon the surface layer material in the surface layer material channel and with the surface and internal layer material injection units in fluid communication with one another, a pullback stroke is effected at the internal layer material injection unit. After a delay interval, at least one physical parameter indicative of a post-pullback pressure of the internal layer material is detected, and an indicator of pullback effectiveness is generated based on the post-pullback pressure indicated by the at least one physical parameter relative to a threshold pressure.

  • Patent number: 10940625
    Abstract: A method and apparatus for extrusion of an article is provided. A die assembly can apply flows of thermoplastic material to an array of reinforcing cables to form a composite extrusion. A slider fabric can be bonded to one side of the composite extrusion. After exiting the die assembly, the slider fabric can act to support the extrudate as it passes along an elongate mandrel, which can cause the base of the slider fabric to change shape from a flat profile to the final internal profile of the article. The extruded article can then be cooled to solidify the material. The die can include cooling for the slider fabric and means for promoting penetration of the thermoplastic into reinforcing cables.

  • Publication number: 20200007602
    Abstract: A method includes preparing images of a remote desktop including an open cloud-application window object corresponding to an instance of a network-hosted application executing on a network, encoding the images of the remote desktop as image frames in a video stream, and transmitting the video stream over the network to a computing device. The images the remote desktop are encoded such that when decoded, reconstructed, and displayed on a local desktop of the computing device, the open cloud-application window object corresponding to the instance of the network-hosted application executing on the network has the appearance and behavior of an open window corresponding to a natively-operating application on the local desktop of the computing device.

  • Patent number: 10350807
    Abstract: A method of and apparatus for extruding an article of uniform cross-section, the article including a thermoplastic material and at least one cable for inhibiting stretch of the article. The cable is supplied to a respective tube and is conveyed between upstream and downstream ends. The thermoplastic material may be supplied to the downstream end of the tube. The thermoplastic material is brought together with the cable to embed the cable within the thermoplastic material, thereby forming a composite extrudate. The tube is configured to at least hinder movement of loose windings of the cable from the downstream end towards the upstream end, which may prevent or at least reduce incidence of “birdcaging”.
