  • Patent number: 11826936
    Abstract: In an aspect, a mold stack may comprise two adjacent components, one at least partially defining a vent adjustable between a molding configuration and a cleaning configuration. A junction of the components may be adjustable between a molding configuration, wherein mating faces contact one another to define a parting line, and a cleaning configuration, wherein mating faces are separated to create a molding cavity extension therebetween and an auxiliary melt barrier prevents uncontrolled flashing from the extension.

  • Publication number: 20220032517
    Abstract: A preform mold (100) including a core plate (210), a cavity plate (410) and a plurality of mold stacks (MS) mounted between the core and cavity plates (210, 410). Each mold stack (MS) includes a core insert (250) mounted to the core plate (210), a cavity insert (440) mounted to the cavity plate (410) and split mold inserts (350) mounted between the core and cavity inserts (250, 440). The core inserts (250) are mounted to the core plate (210) by fasteners accessible from a rear side of the core plate (210). When the mold (100) is assembled, the core inserts (250) can be secured by the fasteners in a fixed condition in which they are immovable relative to the core plate (210). Also disclosed is a method of aligning the core inserts (250) by securing the core inserts (250) from a floating condition, in which they are able to slide relative to the core plate (210) along a sliding interface therebetween, to the fixed condition.

  • Patent number: 10455840
    Abstract: A bread product and method of manufacturing the artisan bread product that eliminates or reduces the need to proof dough after thawing is discussed. One example method comprises mixing ingredients to create a dough, bulk fermenting the dough to create a non-uniform cell structure and to eliminate or reduce proofing after receipt by a restaurant, sheeting the dough, a sheeter being adjusted to allow dough sheeting while substantially maintaining the cell structure, portioning the sheeted dough into portions according to desired sizes while substantially maintaining the cell structure, freezing the portions to create frozen portions, and packaging and shipping the frozen portions while substantially maintaining the cell structure, the bulk fermenting of the dough prior to the sheeting thereby enabling, at least in part, a restaurant to receive the frozen portions, to retard thawed portions of dough, and to bake the portions of dough after retarding without proofing.

  • Patent number: 9894773
    Abstract: Embodiments of the invention relates to adding test access to a back-drilled vertical access interconnect (VIA) of a printed circuit board (PCB). A VIA is either formed or provided as an opening through layers of the PCB. The VIA is countersunk from one of the two openings to the PCB prior to plating to form a surface that can be used as a test target. The countersunk VIA is subject to plating so that the interior walls and surfaces of the VIA are covered with a conductive material. The plating is removed along the walls of the countersunk section of the VIA, so that the plating remains on the shoulders and the non-countersunk section of the VIA with the shoulder in communication with a trace internal to the PCB. The back-drilled VIA with the plating configuration provides an internal conducting surface for contact while mitigating interference associated with a VIA stub.

  • Patent number: 9347984
    Abstract: An apparatus includes a top plate and an extension card surrounding a space for a small electronic assembly. The extension card and small electronic assembly are mounted to the top plate. The apparatus includes a plurality of test probes extending through the top plate and moving relative to the top plate. A portion of the test probes are positioned to contact the extension card and a portion are positioned to contact the small electronic assembly when the test probes move with respect to the top plate. The apparatus includes a vacuum box in contact with the top plate and surrounding the extension card and small electronic assembly. The top plate moves relative to the test probes so the test probes contact the extension card and the small electronic assembly in response to a vacuum force evacuating an area under the top plate and within the vacuum box.

  • Publication number: 20150110916
    Abstract: Disclosed herein is, amongst other things, a mold stack that includes a core insert, a core ring, and a split insert that are configured to cooperate, in use, to define a molding cavity. The core insert defines a ring seat on a medial portion thereof upon which the core ring may be seated, in use, in cooperation with a mounting interface thereon. The split insert defines a pocket that extends coaxially through a second projecting portion thereof within which to receive a projecting portion of the core ring. The core ring and the split insert being further configured to define a core ring-to-split insert parting line that is within the pocket of the split insert. The core ring further defines a first split insert seat for receiving the second projecting portion of the split insert.
