Abstract: ABSTRACT OF THE DISCLOSURE      A dual spark plug ignition engine is equipped with an EGR (exhaust gas recirculation) system.  The two spark plugs in each combustion chamber are simultaneously energized to produce sparks to ignite the charge in the combustion chamber under a normal engine operating condition, whereas the spark plugs are energized with a predetermined phase difference from each other under high power output engine operating conditions.     In this manner, excessive engine noise and vibration under high power output engine operating conditions are avoided, and carbon and oil deposits are burnt off by the second plug which is also maintained at a suitable temperature to prevent thermal damage thereto.

Abstract: Abstract of the Disclosure Process for the selective hydrogenation of poly-unsaturated compounds with a metallic catalyst. The selectivity is increased and trans-isomerization is decreased by carrying out the hydrogenation in the presence of a catalyst to which, before the hydrogenation is started, an external potential, differing from the naturally occurring equilibrium potential, is applied while in contact with an electrolyte, such as a quaternary ammonium salt, dissolved in a liquid, such as an alcohol or a ketone.

Abstract: ACHROMATIC UNIT MAGNIFICATION OPTICAL SYSTEM     Abstract of the Disclosure A unit magnification optical system having micron resolution capability over a broad frequency spectrum.  A spherical concave mirror is used to provide unit magnification at high numerical aperture with respect to object and image planes which are both located at or in the proximity of the center of curvature of the mirror, or the optical equivalent thereof.  A first refractory element optically close to the object and image planes corrects longitudinal chromatic aberration of the principal rays while a second refractory element optically close to the mirror corrects residual longitudinal chromatic aberration of the marginal rays.  In the preferred embodiment, a double prism arrangement located between the first refractory element and the center of curvature of the mirror optically reflects the object and image planes to parallel opposed positions having a common axis perpendicular to the axis of the mirror,  The system may be used for either step-and-repeat or scanning exposure operations in fabricating microcircuits.

Two of three, coaxial, circular pieces of sheet metal define a bearing pocket, which axially and radially locates a bearing unit, and a V-belt receiving groove which, in the preferred embodiment, is spaced outwardly and radially aligned with the bearing pocket for proper resistance to belt tension.  The marginal edge of the gener-ally planar, third piece is bent and clamped around the periphery of a conical brace extending from the flared edge of the V-belt groove on one of the first two pieces to form a radially extending friction wheel engaging disc.  Either the third piece, or a fourth circular piece of sheet metal clamped between the third piece and conical brace, may radially locate a second, axially self-locating bearing unit which is coaxial and spaced an axial distance from the first bearing unit to prevent preloading of the assembly and to reduce rotational wobble due to any bearing eccentricities or slight bearing misalignment.  The bearing units preferably include internal seals.  An external seal retained by the bearing pocket may also be included.
