US Patent:

H7650, Apr 3, 1990

Filed:

May 23, 1989

Appl. No.:

7/361460

Inventors:

Daniel Yu - University Park MD
Charles D. Corum - Abingdon MD

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

F02K 304

US Classification:

60264

Abstract:

The temperature of heated exhaust gases from a gas turbine is increased to value sufficient to vaporize fog oil to form smoke. The turbine itself is unmodified and requires no bleed air control valve at the air inlet to the compressor to regulate exhaust gas temperature.

International Classification:

F41H 906
F28D 710

US Classification:

165163

Abstract:

A heat exchanger and heater of a tube type is provided for heating a liquid n a coiled type housing having an inlet and an outlet for liquid of various types. Hot materials in a gas flow are introduced into the system and a liquid is vaporized to heat the heat exchanger system. In a second embodiment of the shell type of heat exchanger and heater is used in the heating of the input liquid. The third embodiment of the heat exchanger and heater system utilizes a frusto-conical shell with a heat coil centrally located in the shell, while a fourth embodiment of the heat exchanger and heater utilizes a cylindrical coil for the liquid to be heated and a temperature sensor for sensing the temperature in the system at end point.

Abstract:

This disclosure provides an investigation of the kinetic uptake properties of water in amorphous PEF and PET across the entire water activity interval at various temperatures, and also investigates the corresponding equilibrium uptake properties at the same conditions. Uptake data were measured using three independent and complementary methodologies, and excellent agreement was observed among all three methodologies. Accordingly, this disclosure provides for methods of plasticizing poly(ethylene furanoate) film by cold water sorption, and provides a plasticized poly(ethylene furanoate) (PEF) film made according to the disclosed methods. Methods for making thin films of PEF are also provided.
