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.

Appl. No.:

6/782463

International Classification:

B21B 3708

US Classification:

72 19

Abstract:

This relates to an applied force monitor which is associated with sheet material forming mechanisms so as to determine whether sheet material is being properly formed by the amount of force applied in the formation thereof. A typical force applying member would be a cam. Suitable strain gauges are associated with the force applying member with the strain gauges being coupled in a bridge having a voltage output which is indicative of the applied force and which is directed to a microcomputer into which suitable indicia is selectively fed and such indicia will include high and low forces which would be indicative of a fault. The microcomputer includes a memory in which the faults are stored and in addition to indicating when individual faults do occur, the memory, when excess faults are determined, will serve to shut down the associated machine. Data may be visually displayed or may be permanently recorded by way of a printer.

International Classification:

B21D 5132

US Classification:

413 26

Abstract:

This relates to a double seam tightness monitor wherein the second operation track of a cam of a double seaming apparatus or can closing machine is modified so as to permit the high dwell portion of the lobe thereof to deflect under loading from the associated cam follower which forces the second operation roll against the double seam component. Suitable strain gauges are associated with the deformable cam track portion and these are coupled in a bridge having a voltage output which is directed to a microprocessor. The microprocessor is provided with selected inputs which in combination with the voltage input from the bridge may be utilized to provide various signals including a high force condition signal, a pass condition signal, and a low force condition signal. There may also be associated with the microprocessor a printer for identifying the station where an abnormal condition exists, the specific force of the abnormal condition, the machine number, the time and the date. There may also be an output signal from the microprocessor which may be observed in several customary manners so as to permit a complete monitoring of the forces effected during the repeated seaming operations.

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.
