Harold C. Hervig - Maplewood MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
H02G 1508
US Classification:
174 73R
Abstract:
Insulative sheath for high voltage cable splices has inner semiconductive member with inwardly directed bosses for positioning the sheath radially of the cable and splice and for contacting the connector of the splice to suppress corona discharge.

Multi-Core Cable Connection For Medium Voltage Cable

View page
US Patent:
43814247, Apr 26, 1983
Filed:
Apr 28, 1981
Appl. No.:
6/258421
Inventors:
Harold C. Hervig - Maplewood MN
Dieter Kehr - Hamburg, DE
Raymond Krabs - Hamburg, DE
Assignee:
Minnesota Mining and Manufacturing Company - Saint Paul MN
International Classification:
H02G 15184
US Classification:
174 73R
Abstract:
A multi-core cable connection for medium voltage cables in which each core connection includes a pair of prefabricated permanently elastic stress control elements, each of which has a sleeve-like main body of insulating material and a conductive sleeve-like insert in the body, extending out of one end thereof and bridging the core insulation and the conductor connector.

Molded High Voltage Splice Body

View page
US Patent:
43775470, Mar 22, 1983
Filed:
Jan 18, 1982
Appl. No.:
6/340513
Inventors:
Harold C. Hervig - Maplewood MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
B29C 500
B29D 300
US Classification:
264262
Abstract:
A method for making a molded high voltage splice body by positioning a conductive elastomeric electrode on a mandrel, positioning an extruded conductive elastomeric sleeve over the elastomeric electrode, sealing the ends of the elastomeric sleeve, placing the mandrel with the electrode and sleeve on it into a mold, injecting a curable insulating compound between the electrode and the sleeve under pressure and curing the insulating compound.

Mold Useful In Sealing Leaks In Pipes

View page
US Patent:
43267351, Apr 27, 1982
Filed:
Oct 14, 1980
Appl. No.:
6/196390
Inventors:
David N. Hunder - Woodbury MN
Harold C. Hervig - Maplewood MN
Assignee:
Minnesota Mining & Manufacturing Company - Saint Paul MN
International Classification:
F16L 5518
US Classification:
285 15
Abstract:
The present invention is directed to an article and processes for repairing fluid (e. g. , liquid and gas) leaks in pipes, including, for example, bell and spigot joints. The device and process of the invention incorporates an elastomeric sleeve that extends around the pipe and longitudinally to either side of the leak. The sleeve contains a resin injection port with means to prevent escape of resin at a pressure above a predetermined pressure, and a fluid venting port with pressure-relief means to permit the escape of fluid at a predetermined pressure above the pressure in the pipe to be repaired.
