Abstract: An apparatus is provided for an intercooler to maximize air flow to a turbocharger. The intercooler comprises an intercooler core comprising an alternating arrangement of air flow passageways and charge flow passageways. The air flow passageways receive an ambient air flow and the charge flow passageways receive a charge flow, such that heat is transferred from the charge flow to the ambient air flow and removed from the intercooler.

A second end tank sealed to a cool side of the intercooler core conducts the charge flow from the intercooler core to a cool fluid outlet. A multiplicity of partitions disposed on the hot and cool sides of the intercooler core are configured to promote a laminar flow through the charge flow passageways.

Abstract: Implementations described and claimed herein provide systems and methods for sorting disc objects, such as coins, into customizable combinations. In one implementation, a singulator is configured to isolate a disc object from a batch of disc objects. A rail is disposed relative to the singulator, and gravity directs the disc object through the singulator onto the rail. A discriminator determines a size and a composition of the disc object as the disc object travels along the rail. The discriminator determines a denomination and a validity of the disc object based on the size and the composition. A sorter is in communication with the discriminator. The sorter ejects the disc object into a chute corresponding to the denomination and the validity.
