Patent number: 10670346Abstract: A heat exchanger assembly includes first and second annular ducts, first and second airflow pathways, and heat exchanger. The first airflow pathway is configured to transport a first airflow and is disposed within the first annular duct. The second annular duct is disposed radially outward from the first annular duct. The second airflow pathway is configured to transport a second airflow and is disposed between the first and second annular ducts. The heat exchanger includes inner and outer portions. The inner portion is disposed radially inward of the first annular duct and is fluidly connected to the first airflow pathway. The outer portion is disposed between the first and second annular ducts and is fluidly connected to the second airflow pathway. The heat exchanger is configured to cool a third airflow with both of the first and second airflows from the first and second airflow pathways.Type: GrantFiled: January 4, 2018Date of Patent: June 2, 2020Assignee: Hamilton Sundstrand CorporationInventors: Donald E.

Patent number: 4481391Abstract: An improved switch head for engaging and making electrical contact between first and second stationary electrical conductors. The switch head comprises lower and upper insulating head sections, biasing means and a contact slug contained within the lower insulating head section for contacting and making electrical connection with the first and second stationary conductors, and clamping means for holding the lower and upper insulating head sections together. The clamping means places the lower and upper insulating head sections in compression when the switch head engages the first and second stationary conductors. The clamping means also applies a force to the lower head section to disengage the switch head from the first and second stationary conductors.Type: GrantFiled: March 31, 1982Date of Patent: November 6, 1984Assignee: Siemens-Allis, Inc.Inventors: Ralph C. Clement, Charles W. Parmenter, William T. Lockwood
