A compression roller device includes markers on roller heads for pressure-rolling over a substrate to form visual indicia that the substrate has been properly pressure-rolled. In example embodiments, there are two roller heads that each have a set of markers and that are spaced-apart with a handle center-mounted between them. In this way, the roller heads have free/unobstructed outer/opposite edges so they can be positioned closely against an obstructing surface or element for rolling substrates in tight spots with limited clearance. Also, the recess defined between the inner/facing edges of the roller heads provides clearance for rolling over any protruding fasteners securing the substrate in place. Further, the spaced-apart marker sets provide for marking the visual indicia on both sides of a seam/joint between two adjacent panels in a panel-and-tape system to show that both longitudinal side portions of the tape have been pressure-rolled.

The invention includes a method of bonding a perfluoroelastomer material to first surface that includes: (a) contacting a first surface with a bonding agent comprising a curable perfluoropolymer and a curing agent; (b) curing the bonding agent to form a perfluoroelastomer material that is bonded to the first surface. In the practice of such method, the bonding agent may be a solution prepared by dissolving the curable perfluoroelastomer and the curing agent in a solvent. In an embodiment of the invention, the perfluoroelastomer material formed in step (b) is a coating layer or, alternatively, the first surface is a surface of a perfluoroelastomer member and the perfluoroelastomer material formed is a perfluoroelastomer weld.

The present invention is a system and method facilitating the application of PVC primer/cement to the inner surfaces of PVC pipes, unions, joints, or connection sleeves, and to the outer surface of PVC pipes. The invention consists of a PVC primer/cement reservoir, a method of filing and pressurizing the reservoir, and forcing PVC primer or cement through a series of tubes and holes in the apparatus and into a foam applicator transferring PVC primer/cement onto the inner surface or onto the outer surface of a PVC union, sleeve, or pipe to a predetermined depth and thickness thus reducing waste of the PVC primer/cement and ensuring an even coating of PVC primer/cement and always applying the same consistent application of PVC primer/cement.

The present invention is a system and methods that facilitates the application of PVC primer (solvent) or PVC glue to the inner surfaces of PVC unions and the outer surface of PVC pipes. The invention consists of a PVC primer (solvent) or PVC glue reservoir, a method of pressurizing the reservoir, and forcing the PVC primer (solvent) or PVC glue through a series of tubes and holes in the apparatus and into a foam applicator which transfers the PVC primer (solvent) or PVC glue onto the inner surface or onto the outer surface of a PVC union or PVC pipe to a predetermined depth thus reducing waste of the PVC primer (solvent) or PVC glue. The foam application housing contains a foam applicator specifically for applying PVC primer (solvent) or PVC glue to either the inner surface of a PCV union or to the outer surface of a PVC pipe giving a uniform application of PVC primer (solvent) or PVC glue.

A deposition system has a multi-material print head, a first reservoir of a first compatible material having particles containing chemical elements similar to a first substrate, a second reservoir of a second compatible material having particles containing chemical elements similar to a second substrate, a third reservoir of an polymer precursor material, and at least one mixer. A method of bonding a joint between dissimilar substrate materials includes functionalizing a first compatible material having chemical elements similar to a first substrate, mixing the first compatible material with a polymer precursor material, functionalizing a second compatible material having chemical elements similar to a second substrate, mixing the second compatible material with a polymer precursor material, and using the deposition system to deposit the first and second compatible materials and a polymer precursor material on the joint between the first and second substrate materials.

A technique for handling an integrated circuit tape assembly having a plurality of integrated circuits supported by underlying dicing tape involves placing the integrated circuit tape assembly on a film frame carrier (FFC) frame, stretching the dicing tape while on the FFC frame, and securing the stretched dicing tape by engaging a spring ring with the dicing tape and FFC frame. Adjacent integrated circuits are thereby inhibited from colliding during shipment or storage for subsequent processing.
