Assignee:
Ecolab, Inc. - St. Paul MN
International Classification:
G05D 706
US Classification:
137 3
Abstract:
This invention relates to an apparatus and method for diluting a chemical concentrate. More particularly, dilution control is achieved by monitoring two flow meters, comparing the flow rate information, and adjusting the diluent flow to achieve a predetermined dilution of the chemical concentrate. An air push is preferably used to deliver the chemicals to the utilization points. Also a controller is used to prioritize requests from the utilization points in a hierarchal fashion.
Solid Product Static Brake For Solid Block Chemical Dispensers
View pageUS Patent:
51942305, Mar 16, 1993
Filed:
Dec 2, 1991
Appl. No.:
7/801693

Assignee:
Ecolab Inc. - St. Paul MN
International Classification:
B01D 1200
US Classification:
422263
Abstract:
A solid product static brake (10) is provided which is employed in cast solid chemical block dispensing systems for slowing a generally downward gravitationally driven movement of the solid chemical block when placed or installed in a chemical dispenser. The brake provides the ability to prevent the destruction of the cast solid during installation due to mechanical shock. The static brake comprises a horizontal base frame (12), and a plurality of rigid blade members (18) extending from the base frame in a generally perpendicular direction. When a new solid block is installed, the blade members contact and slow the solid block as it falls into the dispenser.
