  • Patent number: 10241019
    Abstract: Some examples of a variable diameter viscometer for evaluating well fluids can be implemented to perform a method. A well fluid including solid well particles is received in a gap formed between a first portion and a second portion of the viscometer. A width of the gap is adjustable during operation of the viscometer. Rheological properties of the fluid are evaluated by applying a shear to the well fluid in the gap by moving the first portion and the second portion relative to each other, and adjusting the width of the gap between the first portion and the second portion based, at least in part, on a size distribution of the solid well particles in the well fluid.

  • Patent number: 9044906
    Abstract: A method and forming tool produce a multi-dimensionally profiled preform from a multidirectional fiber composite material. A tensioning frame envelops top and bottom tool components and fixes the fiber composite material so it is allowed to be subsequently fed-in under frictional engagement. In order to compensate for excess material in regions where a shaping gap has a weaker profile, the tool components have forming elements arranged in the edge trimming zone of the preform and defining between them a drawing-through gap for the material. The drawing-through gap becomes increasingly the shape of a bead in synchronism with the tool components closing movement, and/or the tensioning surface of the tensioning frame is vertically adjusted relative to a tool component inlet surface in the forming phase such that a drawing edge for the material is formed in the tensioning surface.

  • Patent number: 9022773
    Abstract: A device and method for manufacturing integrated circuit packaging using a mold plunger with position compensation in a manufacturing setting. In an embodiment, a compensating mold plunger, which may be used during the manufacture of an integrated circuit package, engages a die set on a carrier and within a bushing. This may be done to inject a mold compound on top of the die/carrier. If the bushing that is housing the die/carrier tandem is misaligned with the plunger in any lateral direction, the amount of pressure may be compromised. A compensating mold plunger includes a flexible portion that allows for the head of the plunger to properly engage the die/carrier despite any possible misalignments. Further, different die/carrier combinations may also be used with a compensating mold plunger because the pressure and force applied may be uniform inside a bushing despite the contents of the bushing.

  • Patent number: 8932043
    Abstract: Disclosed is a plastic trim reclaim process that recycles otherwise wasted trim into for reuse or densified composite bricks for resale. The device combines four sections to process trim scrap from a typical plastic extrusion process. The four sections comprise an input and feed section, a grinding and pre-sizing section, a compaction and sizing section, and a repelletizing and recovery section. The final product takes one of two forms: a compacted plastic brick or pellet-sized beads that can be directly reused in a new extrusion process. The compaction and sizing section utilizes a heating chamber and ram to force ground trim through an extruder, which is then cut into sections to form brick. The repelletizing and recovery section utilizes an extrusion process that feeds into a cutting plate, whereafter the sized pellets are cooled to solidify their structure prior to being vacuum transported into a container for reuse.

  • Patent number: 8814556
    Abstract: A method for manufacturing a sheet having a shape transferred thereon, in which a sheet-like base made of a thermoplastic resin is placed between an imprint mold and an intermediate base and the sheet-like base is then pressed by a pair of pressing plates to imprint the shape of surface irregularity of the imprint mold to the sheet-like base. The sheet-like base is pressed such that, when pressing force of the pressing plates is maximum, an imprinting pressure difference is present in an imprinting surface of the imprint mold, a maximum imprinting pressure section is present in the imprinting surface, and a portion where the imprinting pressure is minimum is not present in the imprinting surface. The method achieves uniform and highly accurate shape transfer without trapping of air.

  • Patent number: 7771187
    Abstract: An embossed carrier tape manufacturing apparatus includes features for integrating with other processing equipment so that other processes such as forming, filling, and sealing the tape can be performed sequentially in one integrated process. The apparatus includes retractable contact spot heaters for heating the tape prior to embossing, along with a unique heat shield arrangement that is interposable between the heaters and the tape so that the process may be paused. Also, a synchronizing apparatus is integrated so that the carrier tape embossing process may be automatically paused for adjusting to the input rate of other carrier tape processing apparatus.

  • Patent number: 7762803
    Abstract: The present invention provides a bottomed cylindrical container, comprising a body wall, a bottom wall, and a ring-shaped foot downwardly extending from the bottom wall, said container being produced by thermo-molding a resin sheet, characterized in that said foot is formed by folding an inner wall by compressed fluid to be fusion-bonded with an outer wall, so as to form the foot comprising the inner wall and the outer wall. The present invention also provides a bottomed cylindrical container, comprising a body wall having a grounding edge at a lower end thereof, and a bottom wall, said container being produced by thermo-molding a resin sheet, characterized in that said bottom wall connects with an upper edge of an inner wall produced by folding back the body wall along the grounding edge and by fusion-bonding it to an inner periphery of the body wall. In addition, the present invention provides the methods for thermo-molding these containers and their apparatuses.

  • Patent number: 7704067
    Abstract: A mold and a method for molding high strength, non-metallic fiber reinforced composite parts having a variety of (e.g., cylindrical) shapes that are lighter in weight than similar parts manufactured from metal. An unmolded non-metallic pre-form having long continuous fibers is placed around a mandrel, and a segmented, adjustable diameter compression ring is disposed in surrounding engagement with the pre-form at an upper position within an inwardly tapered compression ring support. The compression ring is formed from a plurality of loose compression ring segments that are initially spaced circumferentially from one another at the upper position of the compression ring support. The mandrel and the pre-form are first heated and then located in a press.

  • Publication number: 20080251975
    Abstract: A molding process and apparatus suitable for use in molding processes, including rapid prototyping processes and short run production processes. The molding process and apparatus entail the use of a reconfigurable screen tool having a housing defining a manifold cavity and a plurality of substantially parallel pins, each having a head protruding from the housing and a shank protruding into the housing. The heads of the pins define a screen surface through which air is able to flow, for example, through gaps between adjacent heads or through internal passages within the pins. The process further includes axially moving the pins to configure the screen surface, preventing further axial movement of the pins relative to each other, and then drawing a vacuum within the manifold cavity and creating a vacuum at the screen surface.
