Abstract: A printhead for three-dimensional printing of concrete includes a main body and a regulator device. The main body includes a multi-stage, convergent-divergent cylinder, shearing blades, a pressure chamber, and a secondary inlet. The pressure chamber surrounds the cylinder for temporary storage and regulated processing of a secondary fluid. The secondary inlet transfers the secondary fluid from the pressure chamber to the multi-stage, convergent-divergent cylinder to form a mixture, which is discharged from the printhead. The printhead can, for example, be used for additive manufacturing of cement-based materials.

Abstract: The present disclosure relates generally to two part adhesive compositions comprising a resin part including a curable resin selected from multifunctional, hydroxyl di-terminated polymer having alkene segments and epoxide segments in the polymer chain; an epoxy di-terminated block copolymer having siloxane moieties and bisphenol A moieties in the backbone and combination thereof and a hardener part including a curative for the curable resin. When mixed the compositions cure to a form that provides hardness but relatively low bond strength to a substrate and which can be removed from metal and other surfaces easily and simply with little residue.

Abstract: Two-part silane modified polymer/free radically curable adhesive systems demonstrating improved strength and percent elongation are provided.

Abstract: Photocurable compositions that have a color change during curing and methods of preparation and use of such compositions. More particularly, the present invention relates to photocurable compositions that that have a color change during curing and are useful for forming topographical features, e.g., spacer features, and/or fold protection coatings on a portion of a membrane surfaces, and particularly on membranes used in osmosis and reverse-osmosis applications, such as membrane filters.

Abstract: A power cable connector includes a housing having a mating end and a cable end. The housing has a chamber extending between the mating end and the cable end. The housing has an engagement feature configured to engage a socket connector extending from a substrate. A flat cable is received in the chamber. The flat cable extends from the cable end. The flat cable has a mating portion extending from the mating end. The mating portion is configured to be received in the socket connector such that the flat cable directly engages a power terminal of the socket connector.
