Abstract: A device for water dechlorination that includes a housing containing a water-soluble dechlorination media, one or more fluid transfer media that passes through the housing that allows the transfer of water and water-soluble dechlorination media between the inside of the housing and the outside of the housing, and a mechanism for directing water to flow through the one or more fluid transfer media. The chlorine in the water is removed or neutralized by the water-soluble dechlorination media released through the one or more fluid transfer media.
Abstract: A retractable window shade comprises at least one spool assembly and at least one track assembly. The spool assembly includes a spool having film windable thereupon with opposing film edges. The film edges have a series of spaced perforations extending therealong. The spool assembly further comprises a motor and clutch assembly configured to rotatably couple the motor to the spool. The track assembly is oriented laterally outwardly relative to the spool assembly and includes a drive chain that is engaged to a sprocket which is coupled to the motor. The drive chain is configured to the engage the perforations of the film for extending and retracting the film during activation of the motor.
