US Patent:

42689775, May 26, 1981

Filed:

Dec 3, 1979

Appl. No.:

6/099665

Inventors:

Joseph T. Geiger - Houston TX

Assignee:

Exxon Research & Engineering Company - Florham Park NJ

International Classification:

F26B 2512

US Classification:

34242

Abstract:

A non-contact seal for thin film treating ovens to prevent leakage of gas both into and out of the oven at the film entry and exit points. An inert buffer gas is introduced into a narrow sealing slit defined between a pair of upper and lower sealing members adjacent the oven opening to buffer the oven gas leakage. An eductor passage also communicates with the sealing slit to carry away gas leakage resulting from thermal diffusion. Apparatus for precisely adjusting the height of the sealing slit to compensate for various film thicknesses and widths are provided. The temperature of the sealing members is regulated by the circulation of a fluid within passageways provided therein, thus to prevent thermal distortions of the slit defining surfaces.

Abstract:

Various implementations include audio systems for controlling audio feedback to user requests. In some particular cases, a headphone system includes at least one headphone including an acoustic transducer having a sound-radiating surface for providing an audio output; at least one microphone for receiving an audio input from a user; and a control system including a recommendation engine, the control system coupled with the at least one headphone and the at least one microphone, the recommendation engine configured to: analyze the audio input for a non-specific request from the user; and provide an audio sample to the user along with a prompt for feedback about the audio sample in response to the non-specific request.
