Indexing pickup monitors fluid pressures from ports at various angles on high or low speed rotating mechanisms in operation. By a simple axial movement of a takeoff connector, angle changing takes place. This device can be adapted for electric current monitoring.
White-pigmented backing applied to the reverse side of microfiche mastheads makes the area opaque and easily readable. This technique is of value for organizations involved in large volume information storage and retrieval.
Micrometeoroid detector-analyzer with ballistic pendulum for momentum measurement and capacitive foils for velocity
Torque wrench with an adjustable drive shaft permits indicator to remain in view when used on sections of equipment with limited access. The shaft is capable of protruding from either side of the wrench head by means of spring loaded balls.
Rocket flight equations, spacecraft construction, interplanetary exploration, solar energy, human engineering, and instrumentation for space flight
Metallic magnetic alloy foil preparation for development of non-destructive readout buffer memory planes using laminated layer technique
Design, development, and fabrication of feasibility model of magneto-optic memory with gadolinium iron garnet platelets
Three-beam technique superimposes a number of patterns in the same plane of a hologram and then uniquely identifies each pattern by a suitable readout process. The developed readout process does not require any movement of parts.
Commercially available roller type desk pad provides an efficient and orderly manner of handling rolled paper tapes for proofreading. The fixture, which is modified to accept Flex-O-Writer or similar tapes and roll them in either direction, reduces the chance of damaging or soiling the tapes through repeated handling.
Three-legged, clear plastic tool is designed so that the angles of each leg correspond with the angles of psychometric chart construction for each of the three required scales. The appropriate edges are tapered to the chart surface.
Integrated, metal oxide semiconductor memories with nonvolatile and electrically programmable characteristics
Flow angle sensor and remote readout system for use with cryogenic fluids
ATS 1 and 3 satellite VHF transponders for ships and aircraft location, communication and remote sensing, discussing performance test results
Photosensitive recording medium consists of thin-film silicone resin deposited on photoconductive substrate. Medium is useful for holographic interferometry studies.
Several display formats were studied. Analog, digital, and some hybrid (analog-digital) formats were considered. It was found that the hybrid displays are superior to digital or analog displays.
Meter indicates from 30 nH to 3 micro H. Reference inductor of 15 micro H is made by winding 50 turns of Number 26 Formvar wire on Micrometal type 50-2 (or equivalent) core. Circuit eliminates requirement for complex instrument compensation prior to taking coil inductance measurement and thus is as easy to operate as common ohmmeter.
Papers are presented which reflect research in the following areas: development of the concept of technology assessment; institutionalization of technology assessment; the interface between law and technology assessment; and assessment case studies. Case studies include hazards of the medical use of X-rays, environmental noise effects in transportation planning, genetic technology, impact of underground coal mining, and aircraft/airport noise abatement.
Articles are presented concerning the historical, theoretical, methodological, and institutional aspects of technology assessment.
