Rotational fluid coupling mechanism circulates a temperature controlled fluid between a stationary heat exchanger and a coolant plate on a rotating platform. The mechanism consists of two concentric cylinders containing one or more flexible tubes which are controlled and positioned in such a way that it eliminates tubing entanglement.
Cyclic radiation technique has been developed for determining absorptance and emittance of metal surfaces. Using this technique both absorptance and emittance can be determined from one set of data, and variable and controlled temperature levels are possible.

On May 7, 1964, at the invitation of Dr. Raymond L. Bisplinghoff, Associate Administrator for Advanced Research and Technology, a conference was held in NASA Headquarters, on the subject "Heat Transfer Computer Programs." The conference was one of several held in Headquarters during the first half of 1964 for review and planning of NASA's research program on space vehicle thermal radiation and temperature control. The conference brought about a useful interchange of information between the NASA Centers, including JPL, on computer programs which had been developed for the thermal design of spacecraft. The conferees concluded that in addition to our annual conference in this area, a useful continuing exchange of information could be through the establishment of a quarterly newsletter issued from Headquarters describing, current efforts. Such a newsletter, on heat transfer. computer programs, has been established and it is hope that the publication of the present proceedings will be a further milestone in advancing the technology of using electronic computers as a tool in the thermal design of space vehicles. The present volume includes all of the formal presentations made by staff members of the various NASA Centers. Their cooperation, which led to a highly successful conference, is greatly appreciated.
Vacuum chamber environmental simulator and X ray camera are used to study the stability of various minerals in extreme environmental conditions. An ion pump creates the desired vacuum. Exact sample positioning is obtained with a bellows sealed linear motion feed-through. Temperature control is by means of fluid conductive heat transfer.
Modified testing system determines tensile properties of irradiated brittle-type metals at cryogenic temperatures. The system includes a lightweight cryostat, split-screw grips, a universal joint, and a special temperature control system.
Electronic packages, environmental control systems, and spacecraft thermal systems integration - thermal analysis data
Selection of space cabin atmospheres including pressure, fire and blast hazard, humidity and temperature control, etc
Heat exchanger maintains a desirable thermal balance in a subject wearing restrictive clothing. A grid of high thermal conductance fibers, in contact with the skin, transfers heat to or from the skin surface by means of a system of ducts, carrying the transfer fluid which is maintained at a controlled temperature.
Fluidic decoder and display device has low-power requirements for temperature control of thermochromic materials. An electro-to-fluid converter translates incoming electrical signals into pneumatics signal of sufficient power to operate the fluidic logic elements.
Apparatus can straighten, anneal, clean, and a tension to stretch a cable one percent to assure uniform cross-sectional area. A conductor passes through temperature controlled distilled water and through a toroid coil. As The conductor enters the water, steam performs the cleaning action. Quenching and annealing also take place.
