  • Patent number: 10406751
    Abstract: A system for separating objects within a stacked powder print bed of nested objects comprises a build box configured to contain the powder print bed. The build box has a build box top and a build box floor. The system further includes an elongated aperture formed in a side wall of the build box, and a de-powdering subsystem configured to mechanically and electrically engage the build box. A separating blade associated with the de-powdering subsystem is configured to be inserted through the elongated aperture and into the powder print bed between a top-most print bed layer of the nested objects and a second print bed layer directly below and contiguous with the top-most layer, thereby forming an isolated powder print bed between the separating blade and the build box top. The unbound powder may be agitated by various techniques and subsequently removed from the objects.

    Abstract: An electrolyte composition for a lead storage battery and a lead storage battery using the same are provided. More particularly, the electrolyte composition of a lead storage battery and the lead storage battery using the same improve stratification of an electrolyte without use of a separate mechanical device by using a natural stirring effect caused by a specific gravity difference between a dispersant having a specific gravity of from about 1.02 to about 1.35 and an electrolyte including distilled water and sulfuric acid. Due to the reduction in mechanical components, the electrolyte composition for a lead storage battery and a lead storage battery disclosed herein have enhanced durability compared to conventional batteries.

  • Patent number: 10166727
    Abstract: A process for manufacturing an object by laser sintering comprises: (i) selecting a powder comprising a polymeric material having a repeat unit of formula —O—Ph—O—Ph—CO—Ph—??I and a repeat unit of formula —O—Ph—Ph—O—Ph—CO—Ph—??II wherein Ph represents a phenylene moiety; and (ii) selectively sintering the powder to produce the object. It is found that the polymer used can be advantageously recycled and blended with virgin material to produce a blend which has very similar mechanical properties and crystallinity compared to the virgin material. Thus, the polymer may be cost-effectively used in laser sintering.

    Abstract: Mold pieces (105 and 110) for molding a layer of mold compound on the interconnect side of a bumped semiconductor wafer (118) include a primary cavity (117) and secondary cavities (120) into which excess mold compound from the primary cavity (117) flows. The secondary cavities (120) include a plunger (130) that asserts a predetermined backpressure that is equal to a desired mold compound pressure on the mold compound during molding. As most of the excess mold compound in the primary cavity (117) is forced to flow into the secondary cavities (120), this advantageously leaves a relatively thin layer of mold compound on the semiconductor wafer (118), which can then be removed, for example by grinding, in a relatively short time. Mold piece (105) further comprises a movable cavity bar (115) that can be moved away from mold piece (105) after molding and be cooled to detach the molded substrate that adheres to the cavity bar.

    Abstract: A method for the manufacture of container preforms in which recycled plastic material is subjected to at least one heat treatment in a recycling machine before it is transferred to a preform machine, where at least a major portion of heat introduced into the plastic material during its heat treatment and storage is transferred from the recycling machine with the plastic material into the preform machine. In a plant embodied for carrying out the method, the recycling machine is coupled with the preform machine either directly or via at least one intermediate storage such that at least a major portion of heat introduced in the recycling machine during a heat treatment of the plastic material can be transferred with the plastic material into the preform machine.

  • Patent number: 7931460
    Abstract: A disposable liquid build material feed cartridge for use in a solid imaging apparatus and a method of dispensing build material for use in such an apparatus with a radiation transparent build material carrier. The disposable liquid build material feed cartridge recovers unused liquid material from the radiation transparent build material carrier and recycles it through a filter into a supply reservoir for reuse. A dispersing roller is employed to express any entrapping air bubbles in the solidifiable liquid build material that is dispensed onto the radiation transparent build material carrier prior to its being imaged.

  • Patent number: 7789037
    Abstract: The invention relates to a device serving both to lay thin layers of powder and to compact them, the device being suitable for being located inside an apparatus containing a powder or powder mixture while it is subjected to the action of a laser. The device comprises a circular cylinder (12) provided with a longitudinal groove (15) formed in an outside surface of the cylinder (12). The cylinder also has a surface (12a) adapted to compact the powder that has been deposited on a deposition zone. By moving the cylinder in rotation and translation, the powder is brought to and deposited on a tray, on which the powder is then compacted by rotating the cylinder in the opposite direction. The invention enables very thin layers of ceramic or metallic powder to be laid in accurate and uniform manner inside a sealed thermal enclosure at a temperature lying between ambient temperature and about 1200° C.

  • Patent number: 7771183
    Abstract: Solid imaging apparatus and methods for use are disclosed that reduce the amount of uncured solid imaging build material remaining on a completed build object following the completion of the solid imaging build process. The amount of uncured build material is reduced through the use of either an uncoating web that removes excess build material from the build object during the course of the building process or an ink jet source of build material that uses only as much build material as is necessary for the fabrication of the build part. Also disclosed is an imager assembly for use with such a solid imaging apparatus that incorporates two or more individual imagers in an array and accounts for variations in the intensity and alignment of adjacent imagers. The apparatus can be modified for semi-continuous operation and for integrating into a manufacturing operation, if desired.

  • Patent number: 7708547
    Abstract: A method of the type in which a strip of rubber is moved continuously from a rubber-supplier device to a consumer device. During the continuous movement and prior to reaching the consumer device, a portion, referred to as the residue, is taken continuously from the strip of rubber. The residue is taken by continuously cutting the strip of rubber. For example, the supplier device includes upstream storage means for storing the strip of rubber from which the strip is moved toward the extruder, and downstream storage means in which the residue is stored. After the strip of rubber on the upstream storage means has been used up, the upstream and downstream storage means are swapped with each other.

  • Publication number: 20100052194
    Abstract: An apparatus and method for releasing a lens moulded in a cavity between posterior (21) and anterior mould (22) sections and adhered thereto. A post (30) is configured to support a flange (20) of the posterior section whilst the anterior section remains spaced from the post. Posterior section is compressed between a pin (40) applied to, an outer concave surface (29a) of the posterior section and the post, thereby initially releasing peripheral regions of the posterior section and subsequently the remaining portions thereof. Upon separation, the anterior section together with the lens (10) drops onto the post so that its outer convex surface (29a) rests on the post. A collar unit (50) with gas channels (53) presses against a flange (200) of the anterior section whilst blowing jets of gas towards an interface between a “monomer” ring (11) formed around the lens. In this manner, initially the “monomer” ring and then peripheral regions of the lens are separated from the anterior section.
