Liquid nitrogen-cooled gamma ray detector system is made portable by attaching the detector to a fixture which provides a good thermal conductive path between the detector and the liquid nitrogen in a dewar flask and a low heat leak path between the detector and the external environment.
Flame-detector-rod holder is easily removed from the wall of a gas-fired furnance for maintenance or replacement of the detector rod without requiring shutdown of the furnace. The holder consists of an externally threaded outer bushing, a sleeve which is held inside the outer bushing with a set screw, and a detector rod assembly which screws into the sleeve.
Method for estimating accelerations of shipping containers and contents on impacting railroad car
Pressure distribution data at subsonic and transonic speeds for calibrating hypersonic conical pressure probe for X-15 aircraft
In large aperture telescope primary reflectors, the primary mirror is fixed with respect to the gravity vector to avoid varying gravity deflection problems. The primary reflector does not become distorted in various positions nor in changing positions.
Procedure for designing localized shell and finite difference computer program applications to Saturn V vibration testing project
Mode coupling effect on response of rigid body to random excitation analyzed, using two degree of freedom model
Piggy-back method of packaging integrated circuits will increase packaging density and design flexibility. It will also eliminate interconnection leads between the die and associated inductances, and thus increase the attainable frequency response of the circuit.
Electromagnetic absorption and scattering by contaminants from Apollo spacecraft
FORTRAN computer program for calculating time dependent temperature distribution over planar thin plates with arbitrary distribution of conductive, convective, and radioactive data
Omnidirectional microwave parallel plate broadband antenna for spacecraft communications
Surface integration analysis of radiation pattern of parallel plate waveguide
Radiation emission from circular waveguide aperture imbedded in plane conducting surface solved using variational and iteration methods
Inertial guidance system design for manned space missions, considering environmental and performance requirements and energy minimization
Explore the source record for details and available documents.
Electrical characteristics of the mesh or screen electrodes used in electron tubes are improved by decreasing the shunt capacitance of the tube while retaining the close spacing needed for the required resolution. Vibrational characteristics are enhanced by raising the natural resonant frequency.
Symmetric parallel plate waveguide reflection coefficient analyzed
Noncavitating and cavitating performance of inducer in liquid hydrogen
