Abstract: A chemical analysis apparatus is disclosed as having a liquid flow train assembly for creating a flowing liquid sample stream guided from a sample inlet through the apparatus in a capillary tubing arrangement at low liquid flow rates, the sample containing an analyte to be measured; a reagents dosing and injection device located downstream the sample inlet for introducing a series of chemical reagents into the sample stream; a reactor where the reagents react with the analyte for producing a colored chemical indicator in the fully reacted sample; and a detection for measuring the chemical indicator, located downstream of the reactor means and being configured to receive the fully reacted sample with the colored indicator from the reactor means. The flow train assembly can intermittently let the fully reacted sample pass through the detector when the measurement of the indicator is not made, and to bypass the detector when the measurement of the chemical indicator in the sample is made.

Abstract: The Water Conservationist is a unique battery operated motorized cleaning device that will do the labor of a many household chores for the consumer. It is unique in the fact that it conserves water while doing all these chores. The stem and actuator in the water compartment controls the amount of water released to clean. There is a great amount of water wasted in all these household chores. It will be beneficial for the environment if this invention is used by the consumers. The thirteen attachments will be used for various chores attached to this cleaning device. It is new for cleaning because it controls the amount of water to be used which will be readily available installed in this invention. The water and attachments are all in one invention.
