NASA NTRS1968

Modulation of low-rigidity cosmic rays and the power spectrum of the interplanetary magnetic field in 1962 and 1965.

Low rigidity cosmic ray modulation and interplanetary medium at solar minimum and at other phases of solar cycle

Jokipii, J. R.↗

NASA NTRS1968

Methods for fabricating CdS thin-film solar cell modules.

CdS thin film solar cells series and parallel interconnection into modules, using soldered or conductive epoxy bonding methods

Ratajczak, A. F.↗

NASA NTRS1968

The modulation collimator in X-ray astronomy.

Modulation collimators determining angular sizes and celestial positions of X ray sources Sco X-1 and Taurus XR-1

Bradt, H.↗

NASA NTRS1968

Predicted performance of a rotating modulation collimator for locating celestial X-ray sources.

Celestial X ray source positions from rotating modulation collimator, predicting performance of collimator

Schnopper, H. W.↗

NASA NTRS1969

Automated microorganism Sample Collection Module

Modified Gelman Sampler obtains representative sample of microorganism population. Proposed Sample Collection Module is based on direct inoculation of selected solid growth media encased in a cartridge at all times except during inoculation. Cartridge can be handled with no danger of contamination to sample or operator.

Gall, L. S.↗

NASA NTRS1969

Sprayed shielding of plastic-encapsulated electronic modules

Metallic coating directly sprayed on electronic modules provides simple and reliable lightweight protection against radio frequency interference. A plasma arc may be used. Aluminum and copper are the most effective metals.

Muller, A. N.↗

NASA NTRS1969

Pocket-sized tone-modulated FM transmitter

Pressure of a button on a crystal-controlled transmitter causes generation of a tone. The tone modulates the FM transmitter which in turn radiates by way of the enclosed loop antenna, through the radio-frequency-transparent wall of the transmitters case to the receiver.
