Abstract: A rotor bearing system includes a mandrel and a plurality of canted cantilever bearing pads supporting the mandrel, such that, when the bearing pads are run-in against the mandrel, the bearing pads generate uniform bearing gaps and alignment. The mandrel and the bearing pads are sized to form a running proximity to exclude the entry of red blood cells or flow entrained contaminant inclusions therebetween during operation, thereby causing the bearing system to operate in an elasto-hydrodynamic regime of mixed- or boundary-lubrication.

Abstract: A device for shielding an electrically powered resistive heating means so as to block and contain the electromagnetic radiation emitted thereby is disclosed. The device includes a cover constructed and arranged to enclose the heating means, the cover having a layer of electrically conductive material and a ground connection for electrically grounding the electrically conductive layer to either system ground or earth potential.

Abstract: Apparatus and method for the uniform dipensing of a conductive epoxy binder in hybrid microcircuit applications. A method is disclosed of uniformly pressurizing a conductive epoxy binder through a small orifice until a droplet of fixed volume forms, setting a predetermined gap size between a contact pad and the droplet in order to control the shape and size of the epoxy droplet left on the pad as the droplet touches it, and then releasing the pressure while reciprocating the dispenser from the pad. Also, apparatus, including a cylindrical limiting means attached to the dispenser tip, is disclosed for ensuring the gap size is constant. Other embodiments of the limiting means provide for the use of a relieved section which assists in preventing contamination and for adjusting means operable to vary the gap size.
