Abstract: A flexible liquid feeding assembly as an add-on device for use with liquid dispensing bottles is disclosed. The flexible liquid feeding assembly contains a flexible tube and a weight feeder for feeding liquid into a liquid dispenser of a liquid dispensing bottle. The flexible tube has a high degree of flexibility, and the weight feeder has a sufficient weight. Such structural features enable the weight feeder to move in the same direction of liquid's movement in the dispensing bottle. Therefore, the flexible liquid feeding assembly provides a continuous liquid supply regardless the bottle's orientations, even when the bottle is in an inverted position. Alternatively, a weight blocker can be used in conjunction with liquid feeding holes on the side of flexible tube. A liquid dispensing bottle containing a flexible liquid feeding assembly is also disclosed.

Abstract: A support assembly for a spray nozzle specifically structured to deliver liquid and/or cleaning chemicals under high pressure to air conditioning coils or large commercial type air conditioning units for the cleaning thereof in order to render operation of the entire air conditioning assembly more efficient. The spray nozzle is adjsutably and removably positioned relative to the air conditioning coils being cleaned thereby eliminating the need for personnel to physically handle and position the spray nozzle during the cleaning proess wherein the presents of personnel is frequently difficult to maintain and dangerous or hazardous to the health of the personnel due to the enclosed and resulting harsh environmental conditions under which such cleaning of air conditioning coils normally takes place.
