Temperature Compensated Gas Meters
US Patent:
4538458, Sep 3, 1985
Filed:
Aug 26, 1983
Appl. No.:
6/526733
Inventors:
Daniel E. Bruce - Turtle Creek PA
John L. Esola - Falls Creek PA
John L. Esola - Falls Creek PA
Assignee:
Rockwell International Corporation - Pittsburgh PA
International Classification:
G01F 322, G01F 1504
US Classification:
73233
Abstract:
A temperature compensator for gas meters is comprised of two serially connected bi-metallic elements extending between the tangent post and the drive shaft from the flow responsive element. The bimetallic elements are reversely oriented whereby each element responds to a given temperature change to produce movement in the same direction as the other with respect to the axis of the drive shaft.
Four Chamber Direct Drive Gas Meter
US Patent:
4422324, Dec 27, 1983
Filed:
Nov 20, 1981
Appl. No.:
6/323330
Inventors:
John L. Esola - Falls Creek PA
Assignee:
Rockwell International Corporation - Pittsburgh PA
International Classification:
G01F 320
US Classification:
73266
Abstract:
Disclosed is a four chamber gas meter in which the diaphragms are directly connected to the crank arms on the control shaft.
Unidirectional Index Drive For Gas Meters
US Patent:
4080827, Mar 28, 1978
Filed:
Dec 20, 1976
Appl. No.:
5/752676
Inventors:
John L. Esola - Falls Creek PA
Assignee:
Rockwell International Corporation - Pittsburgh PA
International Classification:
G01F 1500
US Classification:
73275
Abstract:
An improvement in the drive to the index, or register, of diaphragm-type gas meters is disclosed, in which the index always runs in the same direction, regardless of the direction of flow of fluid through the meter.
Pressure Regulator
US Patent:
5009245, Apr 23, 1991
Filed:
Sep 20, 1990
Appl. No.:
7/587621
Inventors:
John L. Esola - Falls Creek PA
David L. Kessler - DuBois PA
David L. Kessler - DuBois PA
Assignee:
M&FC Holding Company, Inc. - Wilmington DE
International Classification:
G05D 1606
US Classification:
1371165
Abstract:
A diaphragm actuated pressure regulator is provided having a molded contoured diaphragm capable of operation in the upper portion of the diaphragm's deflection stroke without experiencing material deformation and thereby preserving the precision of the diaphragm's response to pressure fluctuations. The pressure regulator includes a curved lever arm for transmitting the deflection of the diaphragm to a displacement of a valve pad which regulates the flow of gas from an inlet through an orifice restriction to an outlet. The lever fulcrum is located in the throat area of the pressure regulator and supported by a guide to provide a high lever ratio which enables a relatively small diaphragm to generate a relatively high valve closing force. In a preferred embodiment of the invention the diaphragm includes an O-ring shaped circumference which is secured between the upper assembly and the lower case of the pressure regulator thereby insuring an air tight seal without the need for an additional gasket or sealant material.
