US Patent:

39956075, Dec 7, 1976

Filed:

Apr 14, 1975

Appl. No.:

5/567582

Inventors:

George Ludwig - Troy MI
William J. Walters - Milford MI

Assignee:

The Bendix Corporation - South Bend IN

International Classification:

F02P 500

US Classification:

123117A

Abstract:

An internal combustion engine for automotive vehicles is started and operated with decreased fuel enrichment when the engine is cold by delaying spark retard as the vehicle is accelerated to save fuel and reduce accumulated pollutants collected during warm up. A valve is provided between the carburetor spark port and the distributor vacuum advance cylinder to permit unrestricted airflow from the vacuum advance cylinder to the spark port at all temperatures and to restrict airflow from the spark port to the vacuum advance cylinder when the engine operating temperature is below a predetermined temperature. When the engine operating temperature attains the predetermined temperature airflow is unrestricted in both directions and the vacuum advance operates in a normal manner.

International Classification:

F02P 510

US Classification:

123117A

Abstract:

An altitude compensated vacuum control system for regulating the vacuum servo mechanism of an internal combustion engine of the type having a distributor with a vacuum servo controlled advance mechanism incorporating a positive stop for maximum spark advance, a carburetor to provide a source of vacuum to operate said vacuum servo mechanism and a vacuum control valve assembly for regulating the vacuum servo mechanism of said distributor. The vacuum control valve assembly receives a spark port vacuum signal from the carburetor to maintain a predetermined vacuum spark advance as the engine begins to accelerate. Upon attaining the predetermined vacuum spark advance and at a given speed, the control assembly becomes operative to sum the initial first predetermined level vacuum signal to a secondary altitude compensated vacuum source signal, which is a function of an engine operating parameter, thereby causing the vacuum servo spark advance mechanism in the distributor to obtain a maximum spark advance by moving to a positive stop within the distributor. This full vacuum advance is maintained independent of the degradation of the vacuum signals as a result of changes in altitude, provided the spark port signal is greater than the full vacuum spark advance signal.

International Classification:

A61M 1600

US Classification:

128147

Abstract:

A respiratory mouthpiece for a positive pressure breathing apparatus made as an integral flexible elastomer molding in an oval concave shape having a ridge along the inner periphery to provide a seal against the outer surfaces of the mouth when pressed against the face and an opening in the center of the mouthpiece defined by a tube to fit over a mouthpiece holder of a breathing apparatus.
