Abstract: A rain draining apparatus for a sliding window assembly of a building mounted within a window opening and having a track and windows slidably retained within the track includes a drain conduit having a linking segment extending from and in fluid communication with a window track inside a building, and having an upright segment extending from and in fluid communication with the linking segment and extending below the window track and opening outside the building, the upright segment being in fluid communication with a check valve; and a pressure equalizing vent structure for equalizing air pressure throughout the drain conduit extending from and opening within the building into the drain conduit upright segment; so that water in the track flows into the upright segment and accumulates as a column above the check valve and then drains through the check valve when the column reaches a sufficient weight to overcome the opposing force of outside air pressure.

Abstract: Apparatus for drying clothes does not require use of gas or electrical energy for generation of heat. A solar collector is used for regeneration of a desiccant, the desiccant being utilized for drying of clothes. A first portion of the solar collector is used to heat ambient temperature air which is used to absorb moisture from a desiccant, flowing in diluted form over a wick in a second portion of the collector. In a third part of the collector the heated air is humidified to a near saturated state. The moist, hot air interacts with water in a condensing heat exchanger, providing at the output thereof both hot water for storage and subsequent other uses and distilled water, along with saturated air at ambient temperature.
