Spinoff from Space Fuel

In 1963, under contract with NASA, Air Products and Chemicals, Inc. built a 32 1/2 ton-a-day plant to meet the soaring demand for liquid hydrogen created by the Apollo missions and J-2 ground testing. Air Product's experience in government research, development and production of liquid hydrogen served as the springboard for a broad variety of practical, Earth-use applications. Today, liquid hydrogen is widely used among many industries including petroleum refineries in gasoline production and chemical and pharmaceutical firms in the manufacturing of fertilizers and drugs. New commercial applications are growing at the rate of about ten percent per year. Input from government research, Air Product's own technology development, and the large space program requirements combined to make the company the prime manufacturer of liquid hydrogen and enabled them to add a new 30-ton plant near New Orleans.

Nacelle Design

Rohr Industries, Inc. specializes in the manufacturing of nacelles, thrust reversers, and other engine components, has made use of the COSMIC program in nacelle work for aircraft like the McDonnell Douglas DC-10, the French/German Airbus and the Boeing 727, 737 and 747 jetliners. They also manufacture complete nacelles for military and business aircraft and are supplying nacelle components for the Boeing 757. The nacelle requires research and development for each type of airplane because of complex airflows around the engine inlet and high pressures on the nacelle skin. The use of the computer program defines the airflow field around turbofan engine nacelle inlet and cowls. Pressures on the nacelle skin are estimated for various flight conditions and structural integrity of the nacelle design. Rohr estimates that use of this program saved six man-months of programmer time necessary to develop alternative software.

Image Processing

Images are prepared from data acquired by the multispectral scanner aboard Landsat, which views Earth in four ranges of the electromagnetic spectrum, two visible bands and two infrared. Scanner picks up radiation from ground objects and converts the radiation signatures to digital signals, which are relayed to Earth and recorded on tape. Each tape contains "pixels" or picture elements covering a ground area; computerized equipment processes the tapes and plots each pixel, line be line to produce the basic image. Image can be further processed to correct sensor errors, to heighten contrast for feature emphasis or to enhance the end product in other ways. Key factor in conversion of digital data to visual form is precision of processing equipment. Jet Propulsion Laboratory prepared a digital mosaic that was plotted and enhanced by Optronics International, Inc. by use of the company's C-4300 Colorwrite, a high precision, high speed system which manipulates and analyzes digital data and presents it in visual form on film. Optronics manufactures a complete family of image enhancement processing systems to meet all users' needs. Enhanced imagery is useful to geologists, hydrologists, land use planners, agricultural specialists geographers and others.

Space-Derived Sewer Monitor

The QuadraScan Longterm Flow Monitoring System is a second generation sewer monitor developed by American Digital Systems, Inc.'s founder Peter Petroff. Petroff, a former spacecraft instrumentation designer at Marshall Space Flight Center, used expertise based on principles acquired in Apollo and other NASA programs. QuadraScan borrows even more heavily from space technology, for example in its data acquisition and memory system derived from NASA satellites. "One-time" measurements are often plagued with substantial errors due to the flow of groundwater absorbed into the system. These system sizing errors stem from a basic informational deficiency: accurate, reliable data on how much water flows through a sewer system over a long period of time is very difficult to obtain. City officials are turning to "permanent," or long-term sewer monitoring systems. QuadraScan offers many advantages to city officials such as the early warning capability to effectively plan for city growth in order to avoid the crippling economic impact of bans on new sewer connections in effect in many cities today.

Pressure Measurement

Pressure Systems, Inc.'s DPT 6400 is a system designed to increase productivity in industrial processes where there is a need for making multiple pressure measurements quickly and with high accuracy. It is applicable in controlling industrial processes in plants that are being upgraded to automated status. In order to automate such plants the pressures at the many loops must be measured, converted to digital information and transmitted to the plant's process control computer. The DPT 6400 serves that function. By employing solid-state pressure sensing transducers whose errors are automatically corrected by a microprocessor, it is capable of highly accurate pressure measurements. Basic DPT 6400 has 64 channels, but the system can be expanded to 256 channels by the addition of "slave" units.

Portable Medical System

Portable Medical Status and Treatment System (PMSTS) is designed for use in remote areas where considerable time may elapse before a patient can be transported to a hospital. First units were delivered to the Department of Transportation last year and tested in two types of medical emergency environments: one in a rural Pennsylvania community and another aboard a U.S. Coast Guard rescue helicopter operating along Florida's Gulf Coast. The system has the capability to transmit vital signs to a distantly located physician, who can perform diagnosis and relay treatment instructions to the attendant at the scene. The battery powered PMSTS includes a vital signs monitor and a defibrillator. Narco has also developed a companion system, called Porta-Fib III designed for use in a hospital environment with modifications accordingly. Both systems are offshoots of an earlier NASA project known as the Physician's Black Bag developed by Telecare, Inc., a company now acquired by NARCO.

A Two-Way Spinoff

Gougeon Brothers, Inc. successfully applied their boat building expertise to a NASA problem in wind turbine development. NASA and the department of Energy began experimenting with large wind turbine machines as an energy alternative to fossil fuels. During the development of a first generation wind turbine generator known as MOD-OA, Lewis Research Center faced the problem of supersize rotor blades made of metal that kept failing under stress. Using the techniques they had developed for fabricating wood composite structures, the Gougeon Brothers went on to build several sets of blades for the MOD-OA system; all worked successfully. Gougeon Brothers acquired new know-how during the course of studying rotor blade aerodynamics which they applied to their boat building. They developed the innovative "aerodynamic mast" for sailboats. Their mast, a strong, lightweight wood composite which needs no supporting rigging and is free to rotate with the wind, could cut a ship's fuel cost by as much as 40 percent.

Human Tissue Stimulator

Neurodyne Corporation Human Tissue Stimulator (HTS) is a totally implantable system used for treatment of chronic pain and involuntary motion disorders by electrical stimulation. It was developed by Pacesetter Systems, Inc. in cooperation with the Applied Physics Laboratory. HTS incorporates a nickel cadmium battery, telemetry and command systems technologies of the same type as those used in NASA's Small Astronomy Satellite-3 in microminiature proportions so that the implantable element is the size of a deck of cards. The stimulator includes a rechargeable battery, an antenna and electronics to receive and process commands and to report on its own condition via telemetry, a wireless process wherein instrument data is converted to electrical signals and sent to a receiver where signals are presented as usable information. The HTS is targeted to nerve centers or to particular areas of the brain to provide relief from intractable pain or arrest involuntary motion. The nickel cadmium battery can be recharged through the skin. The first two HTS units were implanted last year and have been successful. Extensive testing is required before HTS can be made available for general use.
