Filed:

Jun 27, 2011

Appl. No.:

13/169592

Inventors:

Bruce Hockaday - Vernon CT, US
Thomas M. Ritter - Wethersfield CT, US

Assignee:

UNITED TECHNOLOGIES CORPORATION - Hartford CT

International Classification:

G01M 15/00

US Classification:

7311201

Abstract:

A station probe employed in a gas turbine engine includes a rake portion having a plurality of sensors for sensing conditions in the gas turbine engine. An environmental container attached to the rake portion includes signal conditioning circuitry that locally analyzes sensor signals received from the plurality of sensors to generate measured values, and a communication module for communicating the measured values to a control room.

Appl. No.:

7/586630

Inventors:

Michael W. Hawman - New Britian CT
Thomas M. Ritter - Wethersfield CT
Timothy M. Remmers - Winsted CT

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

G01N 1507

US Classification:

73 2801

Abstract:

A turbine engine debris ingestion monitor has an acoustic emission sensor 18, 18a mounted on a surface 14, 14a disposed in an air flow stream of a turbine engine 12. The sensor converts acoustic emissions 16, generated by particles of debris 10 impacting on the surface, into an electrical signal. A counting circuit 22 (FIG. 2) processes the signal resulting in an output, indicative of the level of debris ingested into the engine, which is recorded in the aircraft's flight data recording system 110.

Assignee:

United States Surgical Corporation - Norwalk CT

International Classification:

A61B 1706

US Classification:

606224

Abstract:

A combined surgical needle-suture device is disclosed in which the suture is received into a socket, or recess, formed within the blunt end of the needle, the entrance to the socket being defined by a circumferential sloping surface which terminates at its outer end in a circumferential cutting edge which provides quick and convenient suture cut-off capability when severing of the suture from the needle is desired.

Assignee:

American Cyanamid Company - Stamford CT

International Classification:

C08G 6370
C08J 328
C08J 710

US Classification:

20415914

Abstract:

The physical properties of structural surgical elements which are made from bioabsorbable materials having a glycolic ester linkage can be controlled so that the rate of strength loss and degradation in vivo is altered to achieve disintegration into fragments suitable for removal from or passage through the body without the need for waiting until the material is absorbed. This is achieved by a method of modifying the element through various chemical and/or physical treatments, preferably irradiation, or combinations thereof, with the result that bioabsorbable structural surgical elements are made more controllable in their strength loss and degradation pattern.

Appl. No.:

6/195531

Inventors:

Thomas A. Ritter - Bristol CT
James C. Bray - Danbury CT
Alan L. Kaganov - Stamford CT

Assignee:

American Cyanamid Company - Stamford CT

International Classification:

A61N 104

US Classification:

128784

Abstract:

A surgical electrode consisting of an insulated stainless steel wire having surgical needles conductively affixed at one or both ends, at least one needle having a pointed end and a nonpointed end with a blind hole or flange in the nonpointed end thereof, and the blunt end of a blunt pointed pin fitted into said hole or flange and a crimp in said nonpointed end of the needle retaining said pin in said hole or flange with controlled pull-out characteristics, said pin conductively and permanently affixed at the other end to said wire, whereby said pin may be pulled out of said blind hole or flange and the blunt end of said pin used as an electrical jack for connection to a pacemaker or similar electric current generating or monitoring device. The electrodes are particularly useful as temporary heart pacer electrodes for cardiac stimulation during and after surgical operations.
