Abstract: A method 10 for making a multi-layer electronic circuit board 98 having at least one electrically conductive protuberance 15 which forms a “via” and which traverses through the various layers of the electric circuit board 98, and further having at least one interconnection portion 102 which supports a wide variety of components and interconnection assemblies.

Abstract: A method for making a multi-layer electronic circuit board 136 having electroplated apertures 96, 98 which may be selectively and electrically isolated from an electrically grounded member 46 and further having selectively formed air bridges and/or crossover members 128 which are structurally supported by material 134.

Abstract: A nozzle 10 having a material outlet aperture 24 which causes received material 28 to be emitted in the form of a streaming sheet 30.

Abstract: A method for making multi-layer electronic circuit board including a pre-circuit assembly 12 and a ground layer 14 which are automatically aligned and bonded together by use of solder material or deposits 26, 28.

Abstract: A novel apparatus for compressing viscous material through openings in a stencil is disclosed. The novel apparatus has a compression head cap which provides a contained environment to direct and to aid the flow of pressurized viscous material through the openings in the stencil. In another embodiment of the invention, the compression head includes a selectively expandable diaphragm and viscous material reception and dispensation apertures. The viscous material reception aperture is formed in close proximity to the material dispensation aperture and this aperture placement to allow the viscous material to be selectively dispensed with a substantially uniform velocity and pressure profile. In another embodiment, the compression head includes a selectively expandable diaphragm which further increases the uniformity of the velocity and pressure profiles.

Abstract: A nozzle assembly 12 having shroud members 26, 28 which selectively emit a material 21 along at least one edge of emitted material 25. The selectively emitted material 21 substantially prevents and/or eliminates the turbulent shear layer which is formed within the emitted material 25.

Abstract: A nozzle 10 having an outlet aperture 26, the outlet aperture 26 having at least one injector 40,42 which is disposed within the aperture 26 and which injects a material 17 within the aperture 26, effective to allow the material to be atomized and to be emitted from the aperture 26 at a substantially identical velocity at each point within the aperture 26.

Abstract: A parking pawl assembly 10 is provided for use in combination with a vehicle of the type including a transmission assembly 12 having a park gear 16. Assembly 10 includes a pawl member 22 which is selectively movable and which allows the park gear 16 to rotate while pawl member 22 is being disengaged from the park gear 16, thereby gradually and smoothly releasing residual torque stored within the park gear 16.
