8/357803

Inventors:

Michael A. Gantt - Granby CT
John A. Larson - New Hartford CT

Assignee:

The Torrington Company - Torrington CT

International Classification:

F16C 3358

US Classification:

384513

Abstract:

There is disclosed a bearing for mounting on a multi-sided shaft having an outer race and an inner race coaxial with and rotatable relative to the outer race. The inner race is formed with a central bore having a plurality of internal corners which accommodate a multi-sided shaft. The central bore is preferably adapted to accommodate hexagonal and square shafts. The central bore has at least one circumferential groove in the bore and an elastomeric ring mounted into the groove. The grooves are formed at such depth that the elastomeric ring is exposed at the internal corners of the central bore whereby when the bearing is mounted the elastomeric material will contact the shaft and dampen the relative motion between the bearing and the shaft.

Filed:

Mar 31, 1989

Appl. No.:

7/332508

Inventors:

Richard L. Bain - Golden CO
John R. Larson - Boulder CO

Assignee:

Resource Technology Associates - Tulsa OK

International Classification:

G05D 700

US Classification:

422109

Abstract:

An apparatus is disclosed for improving the transportability of a hydrocarbon stream by reducing its viscosity. The apparatus comprises a reactor vessel useful for providing an incremental amount of heat to a hydrocarbon stream by the introduction of an oxidizing agent into the core portion of the stream. The reactor comprises an influent conduit and an effluent conduit in heat exchange relation with each other, at least one oxidant injection nozzle located in either or both the influent and/or effluent conduits, a conduit to transport oxidant to the nozzles and a valve in the oxidant conduit to control oxidant flow to the nozzles. The reactor can also contain temperature monitors in the influent and/or effluent conduits and an oxidant flow controller device responsive to output from the temperature monitors and adapted to adjust oxidant flow to maintain temperatures in the reactor reaction zone within a preselected range.

International Classification:

C10G 914
C10G 900

US Classification:

208132

Abstract:

A method is disclosed for improving the transportability of a hydrocarbon composition by passing an influent feed stream of composition into a downcomer to provide a hydrostatic column of fluid. The influent stream is heated by heat exchange with an effluent product stream wherein at least one of the streams is in turbulent flow. The feed stream is pressurized by the hydrostatic pressure head to a reaction pressure of at least about 1000 psi. The heated and pressurized feed stream is contacted with an active heat source in a reaction zone to increase the temperature of the feed stream to a reaction temperature of between about 300. degree. C. and the coking temperature of the hydrocarbon composition. The temperature differential between the active heat source and the feed stream in the reaction zone is maintained at less than about 30. degree. C. to provide a treated effluent stream which is brought into heat exchange contact with the influent stream.

Appl. No.:

8/294220

Inventors:

Joseph F. Braza - Simsbury CT
John A. Larson - Collinsville CT

Assignee:

The Torrington Company - Torrington CT

International Classification:

C22C 3700
C21D 109

US Classification:

148321

Abstract:

A bearing blank is cast or machined of cast iron to a configuration near a final shape of a desired bearing element. A first surface of the bearing blank, corresponding to a sliding surface of the desired bearing element, is remelted while other portions of the bearing blank remain in a solid state. The remelted first surface is quenched such that fine particles of iron carbide precipitate in a remelted zone having an increased hardness and a decreased presence of graphite particles. A bearing element having a core portion composed of cast iron and an integral first surface portion including a precipitate of fine iron carbide particles, and having greater hardness and lesser incidence of graphite particles than the core portion, is also described.

Appl. No.:

6/403245

Inventors:

John P. Larson - Granby CT
Robert J. Japenga - Simsbury CT

Assignee:

Emhart Industries, Inc. - Farmington CT

International Classification:

C03B 716

US Classification:

65 29

Abstract:

A method and apparatus for controlling the delivery of gobs to each section of a multiple section glassware forming machine to assure that no one section can authorize the delivery of a gob of molten glass to any other section. The invention discloses means for monitoring the time of occurrence within a machine cycle of the delivery enable pulse from each section and for determining whether this delivery enable pulse occurs within a predetermined time window. In the event either the leading or trailing edge of this pulse occur outside predetermined time windows, the gob interceptor associated with the machine is activated to reject the gobs intended for that section. The invention also discloses means for monitoring the motion of a gob interceptor to provide assurance to an operator that the interceptor has moved to either a delivery or intercept position in a timely manner. The time lag between a command to the interceptor and the interceptor's actual arrival at a predetermined position is monitored and it exceeds a predetermined value a command is given to the retract mechanism associated with the gob distributor to retract the distributor to prevent delivery of gobs to all sections of the machine.

International Classification:

C10G 900
C07C 3700

US Classification:

208106

Abstract:

A method is disclosed for reducing the viscosity of a hydrocarbon feed. The feed is heated from an initial temperature to a second temperature and an oxidizing agent is introduced to oxidize components in the feed and provide heat to increase the temperature of the feed to a reaction temperature. The reaction temperature is maintained to produce a reaction product having a lower viscosity than the feed.
