Abstract: A dual spherical ball clamp is employed to allow for pivotal adjustment of a robotic arm to support an object in a desired position. The clamp is formed by a pair of clamp halves bolted together to form a pair of sockets. Each socket receives a spherical ball of an arm. The faces of the dual spherical ball clamp are slightly inclined outwardly with respect to the lower surface of the dual spherical ball clamp to provide for additional range of motion of the arms.

Abstract: A heat exchanger is provided including a first aluminum extruded header spaced apart and arranged essentially parallel to a second aluminum extruded header. The first and second headers include a plurality of parallel passageways extending therethrough along a longitudinal axis thereof. The passageways are fluidly interconnected by at least one transverse cross-drilled bore extending essentially perpendicularly to the longitudinal axis. A core assembly is secured between the first and second headers including a plurality of fluid conduits and heat radiating fins surrounding the fluid conduits. A by-pass valve assembly fluidly communicates with the headers and core assembly while providing an alternate pathway independent thereof. Preferably, the by-pass assembly is responsive to fluid temperature and/or pressure for directing fluid flow either into or exterior of the heat exchanger core assembly.
