A support for mounting an air conditioner for operative disposition in a window, while being free of any supports external to the window and of any metallic fastener contact with the window, includes elongated top and bottom members of lightweight construction, sized and shaped to extend parallel to an interior window sill of the window, with opposite ends of the top member extending beyond vertical side jambs of the window. First and second transverse members of polymeric molded construction extend between the top and bottom members to define a receptacle sized and shaped to slidably receive the air conditioner therein and to interferingly engage an elongated flange extending along an upper surface of the air conditioner. The top and/or bottom members include hand-holds and the top member is adjustable to accommodate windows of various sizes.

First and second transverse members of polymeric molded construction extend between the top and bottom members to define a receptacle sized and shaped to slidably receive the air conditioner therein and to interferingly engage an elongated flange extending along an upper surface of the air conditioner. The top and bottom members include molded hand-holds and demarcations/score lines to facilitate trimming to desired widths.

An automatic titration system and method in which the titrant is generated electrolytically and a two-position slider type ceramic sample valve, reliably, accurately and repetitively obtains a volumetric sample from a process loop and introduces it to a titration cell containing a generator or working compartment and an auxiliary compartment separated by a porous frit. The system also includes a two-position slider type ceramic reagent valve for introducing reagent into the titration cell. Titrant created at a generator electrode surface is dispersed into the bulk of the solution by a magnetically coupled impeller in the working compartment which mixes and also pumps the contents of the cell through the reagent and sample valves in a closed loop. Generator and auxiliary electrodes are connected to a current source which provides the electrolysis current. The progress of the titration is monitored by indicating and reference electrodes in the titration cell connected to an appropriate endpoint indicator, output of which is compared to a known setpoint corresponding to the titration endpoint. The total charge delivered to the generator and auxiliary electrodes during titration is measured by a timer or integrator and read out as a trend output signal. The automatic titration system and method of this invention advantageously lends itself to microprocessor control over the titration reaction and titrator sequencing.
