Patent CA-2250519-A1 (CA)
Title: Precision liquid dispenser device
Inventor: BOUDREAU NORMAND
IPC: G01F11/30
Filed: 1998-10-15
Abstract: The dispenser device of the invention comprises a liquid storage tank overlying an intermediate chamber partially filled with liquid. The top storage tank is fluidingly linked to the intermediate chamber, and a first valve controls the liquid flow under the gravity force from the top tank into the intermediate chamber. The intermediate chamber comprises on its bottom wall an outlet port for allowing liquid to be dispensed therethrough under the gravity force and under the pressure of the overlying liquid, the liquid flow through the chamber outlet port being controlled by a second valve. A small computer is linked to the first and second valves and to a float gauge floating on the liquid located inside the intermediate chamber. Thus, the computer detects by means of the float gauge any variation of the level of liquid inside the intermediate chamber. In use, the data concerning the precise quantity of liquid which is desired is entered into the computer. The computer sends a signal to the second valve to allow liquid flow during a precise time period out of the intermediate chamber, this liquid being collected in a suitable receptacle. To be certain that the quantity of liquid dispensed through the second valve is precise, the height of the liquid inside the intermediate chamber is maintained constant, so that the pressure applied on the outflowing liquid by the overlying liquid remain constant. This is accomplished by a signal, through the computer, of the float gauge to the first valve to allow liquid refill from the tank into the chamber.

Title: Removal of fluoride-containing scales using aluminum salt solution
Inventor: WEBSTER GEORGE HENRY JR
IPC: C10J/
Filed: 1997-07-14
Abstract: Fluoride-containing scale can be removed from metal surfaces such as titanium, titanium alloys, nickel alloys, and stainless steel by contacting the metal surfaces with an aqueous salt solution of an inorganic acid, including its hydrates. The cationic portion of the salt can be aluminum, iron and mixtures thereof. The anionic portion of the salt can be a chloride, a nitrate, a sulfate, and mixtures thereof. The contracting occurs in the absence of the addition of an acid, such as hydrochloric, nitric, or sulfuric acid. The presence of the aqueous salt solution with the dissolved fluoride scale does not accelerate or increase the normal rate of metal corrosion that can occur in the absence of the aqueous salt solution or any acidic cleaning agent.
