Abstract: A filter assembly is provided for a manifolded water filtration system and includes a filter element, a brine seal located at the top of the filter element and engaging a boss depending from the system manifold. The brine seal isolates a rinse water discharge port, communicating with a an outlet of the filter element, from an untreated water inlet port formed in the boss so as to ensure that the water to be treated passes through the filter membrane as opposed to directly out of the rinse water discharge port. This configuration eliminates the need for an exterior feed line, thus simplifying the system and preventing vibration during system start-up. The brine seal also structurally reenforces the filter element, facilitates assembly of the filter, increases the capacity of the assembly, and reduces the chances of failure and leakage.

Abstract: A system for reducing higher order nonlinearities in the linearized output of a dimension gauging probe in which the dimension gauging probe provides an output varying inversely with the physical dimension gauged which is in turn linearized to a signal varying proportionally with the physical dimension. Higher order nonlinearities, an error condition, which deviate the correspondence between the gauged dimension and the output from a linear or straight-line function, are reduced by feedback of the linearized output to the probe and, preferably, by feedforward of a portion of the probe output signal to the linearized signal.
