Abstract: An illustrative example embodiment of a method of making a concrete expansion joint insert includes moving a material including a resin having a melt temperature through a die having a flow passage that ends in an exit having a selected geometry, increasing a temperature of only a segment of the die near the exit to an elevated temperature that is at least 1.5 times the melt temperature, and increasing the temperature of a portion of the material to an increased temperature above the melt temperature through contact with the segment having the elevated temperature.

Abstract: An illustrative example embodiment of a protective cap assembly includes a plurality of protective caps each including a stem and a top plate. The top plates each have a plurality of edges. One of the edges of a first one of the protective caps is connected to an adjacent edge of a second one of the caps in a manner that allows for manually separating the first or second one of the protective caps from the assembly.

Abstract: A method of retraining brainwave patterns using direct electrical stimulation feedback comprises: securing two or more electrodes to a subject's scalp and/or ears; acquiring EEG signal(s) on at least one channel; amplifying the EEG signal or signals via differential amplifier means; digitizing said EEG signal or signals via Analog-to-Digital converter means; selecting at least one of said channels from which to derive feedback; creating at least one digital-domain representation of said selected EEG signal or signals; creating a signal or signals representing at least one time-domain “distortion” of said digital domain representation or representations by time distortion means; differentiating said time distorted signal or signals; and introducing said differentiated signal or signals back onto the pairs of input leads via coupling means, wherein said differentiated signal or signals are thus input directly to the brain and nervous system, bypassing the normal systems of perception.

Abstract: A method for attaching a substrate to a plastic profile, in which a profile is extruded from a plastic material. The profile has at least two separable legs that define a channel for receiving a substrate. A substrate is placed in the channel and a liquid material is injected, which upon hardening will join the substrate with the profile.

Abstract: A method and apparatus for forming a molded plastic part such as a body side molding for a motor vehicle in which a ribbon of plastic material is extruded through a shaping die of an extruder and is thereafter moved through a runner and into an elongated closed end mold cavity having a size and shape conforming to the body side molding. The cross-sectional area of the extruded ribbon, the runner and the mold cavity are substantially equal and the entire path of the plastic material moving through the extruder, runner and mold cavity is maintained at a temperature above the melting point of the plastic material so that the plastic material moves smoothly and quiescently along the path under relatively low pressure and with minimal disturbance. The invention process substantially eliminates swirling and streaking of metal particles which are commonly dispersed in the plastic material to give the body side molding a metallicized, glossy appearance.
