International Classification:

G03D 302

US Classification:

354323

Abstract:

A self-contained photo developing machine is provided. The apparatus includes a developing canister which holds the photo processed material on a central shaft, a compact manifold injection structure which infuses the attached canister with the developing solutions, a valving structure which provides the selected developing solutions to the manifold injection structure, a drain assembly which evacuates the used developing solutions from the canister for seperation and recovery of the different chemicals used, and a computer control system which selectively and automatically controls the entire developing process. A radially extending arm is often included to selectively pump the desired chemical from the solution storage tanks to the canister and subsequently evacuate the spent chemicals to an independently selectable solution recovery tank.

Abstract:

An internal combustion engine comprising a crankshaft rotatable about an axis, one or more pairs of cylinders opposed from each other on either side of the crankshaft, one or more pairs of pistons alternately moveable within the cylinders by combustion therein, and a common rod connecting the pair of pistons, the pistons and common rod being linearly slideable in a first direction. A linear bearing is disposed on the common rod between the pair of pistons and connects the common rod to the crankshaft, the linear bearing being slideable in a second direction normal to the first direction. As the pair of pistons alternately move within the cylinders, the crankshaft is driven by movement of the common rod and pair of pistons back and forth in the first direction and movement of the linear bearing back and forth in the second direction.
