Abstract: A chiller for cooling a beverage includes a reservoir configured to hold a heat exchange fluid and an evaporator coil arranged within the reservoir. The evaporator coil includes a plurality of windings configured to circulate a coolant, and projections extending from an exterior surface of one or more of the plurality of windings. The chiller further includes a chiller coil arranged in the reservoir, wherein the beverage is configured to flow through the chiller coil. When the coolant is circulated through the plurality of windings of the evaporator coil, a bank of frozen heat exchange fluid forms on the windings and on the projections.

Abstract: A motor system comprises a rotor shaft, and a magnetic drive motor and a capacitive drive motor. An engagement system is configured for selectively engaging one or both of the magnetic drive motor and the capacitive drive motor with the rotor shaft, in order to rotate the rotor shaft at a desired rotational speed and generate a desired output torque. An actuator may be coupled to the rotor shaft in order to convert the rotational speed and/or output torque (or a rotational position of the rotor shaft) for operation on a load, for example to position the load rotationally or linearly with respect to the rotor axis, or to exert a force or torque on the load.

Abstract: A two-wire field-mounted process device with multiple isolated channels includes a channel that can be an input channel or an output channel. The given input or output channel can couple to multiple sensors or actuators, respectively. The process device is wholly powered by the two-wire process control loop. The process device includes a controller adapted to measure one or more characteristics of sensors coupled to an input channel and to control actuators coupled to an output channel. The controller can be further adapted to execute a user generated control algorithm relating process input information with process output commands. The process device also includes a loop communicator that is adapted to communicate over the two-wire loop.

Abstract: A process fluid measurement system provides a first measurement relative to process fluid flowing in a pipe. An additional measurement of process fluid flow velocity in the pipe is combined with the first measurement to provide a simplified indication of mass fluid flow and/or density or other fluid parameter. In some embodiments, the first measurement is a differential pressure measurement. Additionally, one embodiment provides a vortex flowmeter having configurable terminations for coupling to a variety of pressure or differential pressure sensors or transmitters for advanced process fluid measurements or calculations.
