Assignee:

Borg-Warner Corporation - Chicago IL

International Classification:

F28F 1900

US Classification:

165 1

Abstract:

A corrodible container for the storage of a corrosion inhibitor to be suitably located in the coolant system of an automotive vehicle or other environment wherein the container has at least a portion thereof formed of substantially the same material as the material forming the heat exchange device in a coolant system so as to corrode when the coolant is partially or wholly replaced by a corrosive liquid such as water. More specifically, an aluminum radiator has a tendency to corrode rapidly where corrosive water is present and the container for the corrosion inhibitor has at least a portion thereof formed of aluminum foil or aluminum sheet material with a thinner portion so that the foil or thinner portion will corrode through to release the corrosion inhibitor into the coolant to minimize corrosion of the heat exchanger and coolant system.

Appl. No.:

6/222456

Brian E. Cheadle - Bramalea, CA

Assignee:

Borg-Warner Corporation - Chicago IL

International Classification:

F28F 1900

US Classification:

165134R

Abstract:

A membrane for the end surface of a container for a corrosion inhibitor for engine coolant where the membrane is exposed to the coolant and corrodes when the corrosiveness of the coolant increases above a predetermined level. The membrane is formed of the same metal or alloy as the radiator and has a thin layer thereon of a second metal except for certain areas where the base metal is exposed so that in a corrosive environment, a galvanic cell is set up between the two metals to enhance the rate of corrosion of the membrane.

Assignee:

Borg-Warner Corporation - Chicago IL

International Classification:

B23C 700
B23B 4900

US Classification:

409134

Abstract:

A method and apparatus by which the degree of wear and useful life limitations of a drill, end mill or other types of metal removal tools can be detected. The method is based on the short circuit current, open circuit voltage and/or power that is generated during metal removal by the utilization of an insulated rotary tool bit to which electrical contact is made by a non-rotating conductor and an insulated or non-insulated workpiece, with an external circuit connecting the tool and workpiece through a measuring device. The generated current, voltage or power shows a sharp increase or change in slope upon considerable tool wear and/or at the point of failure.

Appl. No.:

6/039995

Inventors:

Robert H. Krueger - Palatine IL

Assignee:

Borg-Warner Corporation - Chicago IL

International Classification:

B01D 3100

US Classification:

210167

Abstract:

A device for the automatic addition of a corrosion inhibitor to a cooling system, such as in an automobile engine, utilizing osmotic pressure. The device includes a container for a concentrated corrosion inhibitor solution with a semi-permeable osmotic membrane in contact with and separating the inhibitor solution from the coolant in the overflow reservoir. With properly inhibited coolant, the osmotic pressures balance, but if the level of inhibitor in the coolant drops, water passes through the membrane to force inhibitor solution through an overflow tube or opening to mix with the coolant and raise the inhibitor level therein to a predetermined value.

Assignee:

Borg-Warner Corporation - Chicago IL

International Classification:

B01D 1102

US Classification:

422265

Abstract:

A device for the automatic addition of corrosion inhibitor into an automobile coolant system when the coolant mixture is diluted by water having an undesirable level of corrosiveness. The device is in the form of a hydrometer having a hollow stem adapted to receive a quantity of a corrosion inhibitor and having openings in the stem wall allowing contact of the liquid in the coolant system with the corrosion inhibitor when the specific gravity of the coolant liquid decreases below a predetermined level.

Assignee:

Borg-Warner Corporation - Chicago IL

International Classification:

F28F 1900

US Classification:

137 93

Abstract:

Means for adding corrosion inhibitor to an engine cooling system utilizing a corrosion detector in contact with the circulating coolant and which is in an electronic circuit to activate a control valve which controls the feeding of corrosion inhibitor solution from a reservoir that is in selective communication with the coolant system. The corrosion detector may be in the form of a probe that measures solution potential or electrical resistance of a metal wire as it corrodes due to the corrosiveness of the coolant. The corrosion inhibitor reservoir is located either in communication with the line between the radiator and coolant reservoir or in a by-pass line parallel with the radiator.
