Abstract: A machine for and method of manufacturing concrete U-wall construction blocks, each having a front wall portion and a pair of stem portions extending from said front wall portion. The method involves providing a system of molding jacket panels, including a core molding assembly having a pair of inside stem jacket panels that are adjustably supportable in a substantially parallel manner during a molding process, and arranged is such a manner that the front wall portion is molded in downwardly facing direction toward a horizontal support surface and completely enclosed in one or more molding jacket panels. Before block molding operations, the thickness of the front wall portion of the U-wall construction block is set by determining the thickness of a front wall surface liner and installing the front wall surface forming liner within the system of molding jacket panels.

Abstract: A continuous-wave (CW) ultraviolet (UV) curing system for solid freeform fabrication (SFF) is provided, wherein the curing system is configured to provide an exposure of UV radiation for one or more layers of UV-curable material. One or more UV exposures may initiate curing of a curable material in the layer dispensed by a solid freeform fabrication apparatus. One approach to provide the single or multiple UV exposures is the use of one or more UV LEDs, which generate UV radiation without generating any substantial amounts of infrared (IR) radiation at the same time. This allows for the curing process to be energy efficient and also allows for the SFF system to be far less complex.

Abstract: The invention is directed to a patterned aerogel-based layer that serves as a mold for at least part of a microelectromechanical feature. The density of an aerogel is less than that of typical materials used in MEMS fabrication, such as poly-silicon, silicon oxide, single-crystal silicon, metals, metal alloys, and the like. Therefore, one may form structural features in an aerogel-based layer at rates significantly higher than the rates at which structural features can be formed in denser materials. The invention further includes a method of patterning an aerogel-based layer to produce such an aerogel-based mold. The invention further includes a method of fabricating a microelectromechanical feature using an aerogel-based mold. This method includes depositing a dense material layer directly onto the outline of at least part of a microelectromechanical feature that has been formed in the aerogel-based layer.

Abstract: A fused filament fabrication printer has a fixed extrusion module having multiple printheads having print tips. The fixed arrangement of the printing heads allows the close spacing of multiple print tips in a printhead unit, and the simple routing of multiple plastic or metal filaments to the individual printing heads.

The heating block incorporates a group of four print tips evenly spaced along a line. Each printing head has a separate filament which is controlled and driven by its own stepper motor through the heating block to one of the print tips. Printing of a part is by control of individual stepper motors which drive filaments through the heating block and through one of the printing tips.

Abstract: A melt cooler and valving system for an underwater pelletizer has a diverter valve that facilitates multiple modes of melt processing. The cooler has a cooler inlet line that conveys the melt to the cooler, and a cooler outlet line that conveys the cooled melt from the cooler. The diverter valve is configured to convey the melt to and from the cooler during a cooling mode of operation, to convey the melt around the cooler during a bypass mode of operation, and to drain the melt from the cooler and the diverter valve during a drain mode of operation. The diverter valve is compact and therefore contains a minimum of product inventory. The valve is streamlined and direct in its bypass mode, and includes a drain capability to allow for faster, easier cleaning of the process line, which in turn provides a fast changeover time with less lost product.
