Abstract: Counterrotating cam and follower apparatuses (C-CAFA) capable of converting reciprocating to rotational motion, and visa versa, utilizing counterrotating cams cooperating with at least one reciprocating cam follower. Apparatus cam counterrotation is ensured to be synchronously timed without necessity of prior art stationary geartrains, by and through apparatus cam follower(s) combining with counterrotating cam surfaces acting as moving follower constraints, provided that disclosed structural limitations, including those regarding cam and follower surface interface engineering slop, multiple degree of freedom cams, rotating and reciprocating follower(s), and electromechanical limitations are met when specified. Optional apparatus usages include reciprocating mass balancer, differential to reverse and or multiply shaft rotations, and apparatus combinations with connecting rods, pistons, cylinders, and or engines.

Abstract: Improved structures, functions, and methods regarding internal combustion engines (ICE's). ICE embodiments disclosed are divided into three groups, all of which have at least one embodiment structurally possessing at least one actively powered fan cooperating with at least one exhaust manifold. All of said embodiments disclosed at least solve the objective technical problem of reducing emissions in an ICE. Said embodiments include both normally aspirated and forced induction ICE's. Said embodiments are capable of operation in two stroke cycle Homogeneous Charge Compression Ignition (HCCI) mode, two stroke cycle spark ignition mode, two stroke cycle combination spark ignition and HCCI mode, or four stroke cycle spark ignition mode. The technical field respecting all embodiments and or their methodologies relates generally to ICE's. Principal uses of the embodiments include enabling the operation of ICE's in the above said various mode or modes.

Abstract: A solar collector assembly with at least one primary locator feature. The solar collector assembly has housing having at least one wall and at least one mirror for directing rays of light toward a secondary objective. Each mirror of the solar collector assembly has a back side and a reflective side and at least one primary locating feature for connecting the mirror to the housing. The primary locating feature has a guide bushing that is operably connected to the at least one wall of the housing. A stud of the primary locating feature has a first end connected to a mirror bracket and second end extending through the guide bushing. The stud has a longitudinal axis that extends between the mirror bracket and the guide bushing for allowing the mirror to be positioned along the longitudinal axis relative to the at least one wall of the housing.
