US Patent:

45674108, Jan 28, 1986

Filed:

Dec 3, 1984

Appl. No.:

6/677411

Inventors:

Ralph E. Martin - Oak Lawn IL
Heino Puidak - Hoffman Estates IL

Assignee:

Continental Can Company, Inc. - Stamford CT

International Classification:

H02P 500
B65G 4300

US Classification:

318332

Abstract:

A capacitance article density monitor which is adjusted to have a zero voltage output when no articles are positioned adjacent a sensor and wherein the output of the circuit may be utilized directly to control a variable speed drive for a machine to which articles are being directed depending upon the density of such articles in a conveying area in advance of the machine. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

International Classification:

C08L 6110
C08L 7508

US Classification:

260 38

Abstract:

Foundry cores and molds for casting metals are prepared by forming a binder comprising a polyol, an isocyanato urethane polymer and a urethane catalyst. The foundry cores and molds of this invention are formed by processes known in the industry as the "cold box" process and the no-bake process. The binder is especially useful for casting non-ferrous metals, for example, the casting of aluminum, magnesium and other lightweight metals. The cores and molds produced for casting aluminum and other lightweight metals exhibit excellent shakeout while retaining other desirable core and mold properties.

Appl. No.:

5/775842

Inventors:

Richard A. Mazur - Downers Grove IL
Ralph E. Martin - Oak Lawn IL

Assignee:

Continental Can Company, Inc. - New York NY

International Classification:

H03K 1302

US Classification:

340347AD

Abstract:

A self-contained data acquisition device or probe capable of monitoring any physical function that can be translated into an analog or digital signal. The data acquisition probe is coupled to a separate translator whereat the stored analog or digital voltage signals are transferred to the translator to be coupled to a display device for displaying the voltage signals.

US Patent:

55385591, Jul 23, 1996

Filed:

May 31, 1994

Appl. No.:

8/252283

Inventors:

David L. Kleimeyer - Columbus OH
Ralph W. Martin - Ashland KY
Robert D. Wines - Hurricane WV

Assignee:

AK Steel Corporation - Middletown OH

International Classification:

B05C 300

US Classification:

118423

Abstract:

The invention includes a vessel (24) for containing a bath (28) of molten coating metal such as zinc, a sink roll (30) submerged into the bath defining a path of travel for a metal strip (12) through the bath with the strip applying force to the roll as a result of tensile load on the strip and a pair of stabilizing rolls (32). Sink roll (30) is supported by a pair of spaced arms (36) and each stabilizing roll (32)is supported by a pair of spaced arms (44). Each roll has a cylindrical body (52) having an outer surface for being in contact with strip (12) and a trunnion (54) projecting axially from each end of the roll body. Each arm (36) has an upper end (38) and a lower end (40), the upper ends being mounted at positions (42) above the vessel and the lower ends for being submerged into the bath. Each lower end of the arms includes means (58) for supporting the roll and means (56) for restraining lateral thrust of the roll. The support means includes an oversized opening (59), a ceramic wear resistant bearing (68) mounted within the opening and a cylindrical sleeve (66) mounted onto each of the trunnions.
