Abstract: A thermoelectric water-chiller system for cooling bottled water, and including a mixing valve which enables dispensing of chilled water, room-temperature water, or a mixture of chilled and room-temperature water. Components needing periodic cleaning are readily removable from the system. A fan-cooled thermoelectric-chip assembly is used to form an ice block which chills the water, and a variable-speed fan is controlled by a temperature sensor to slow the fan speed when chilling to a desired temperature is achieved, and to maintain the ice block at an optimum size.

Abstract: The present invention provides a branch type seal which is self adjusting for use on existing pipelines of various diameters and materials. The invention includes an adapter with a longitudinal bore which is axially aligned with the hole in the main pipeline. A plurality of deformable retaining fingers extending outward from the adapter engage a compression seal. The retaining fingers are deformed to contour to the pipeline surrounding the hole by a hubbed retainer which places pressure on the retaining fingers deforming the fingers and compression seal against the wall of the pipeline creating a leak proof seal.
