Separable brazed stainless steel tube joints using gold-nickel brazing alloy
Feed-through device connects RF power to an RF coil in a vacuum chamber. The coil and leads are water cooled and vacuum tight seals are provided at the junctions. The device incorporates silver soldered copper tubes, polytetrafluoroethylene electrical insulators, and O-ring vacuum seals.
Electrical shorting cap provides pin alignment, protection from stray voltages, and inspection capabilities. A Teflon straightener insert is built in to overcome any problems with bent or misaligned pins. A clear plastic bottom allows for inspection of the presence and condition of the pins.
Shielding effectiveness and electromagnetic interference tests on multiplexer cables
Joining techniques for zero leakage ducts and tube connections
Methode contact cracking failure and subsequent production quality control
Commercial push gage has been modified to enable rapid, accurate testing of paddle pins in distributors, bullet pins and patch boards. The purpose of the gage is to ensure that the pins will not break electrical contact when they are subjected to a minimum, preset pressure.
U-tube containing liquid indicates pressure differences in a leakage tester. This tube, connecting two containers, indicates that the amount of leakage over a set period of time is calculated from the pressure and gas volume.
Split-half cover eliminates the surface marring and dirt penetration problems previously encountered during handling and cable assembly. Metal retaining ring slips over the two plastic halves to hold them in place.
Reliability studies of single interrogation and single data cables used in prototype addressable time division multiplexer system
Nonflammable materials capable of fabrication into flexible oxygen hose for spacecraft life support system
Termination adapter replaces braid ring and ensures permanent attachment and grounding of sheath wires. The inner ferrule of the termination is slipped inside the exposed ends of the sheath wires and the outer ferrule is placed over the wires and crimped in place to secure the wires for grounding.
Rectangular electric conductors for conductor cables to withstand spacecraft vibration and controlled atmosphere
Leakproof soft metal seal for use in very high vacuum systems operating at cryogenic temperatures
Commercial and governmental flat conductor cable for connenting and terminating hardware
Ultraminiature catheter cables that are stiff enough for intravenous insertion yet flexible at the tip, sterilizable, and economical are fabricated entirely from commercially available parts. Assembly includes air passageway for reference pressures and coaxial cable for transmission of signals from the tip of catheter.
A molding study of compounds based on copolymers of highly fluorinated olefins and of flame retardant silicone is reported. Both single cavity and four cavity molds having size 22 and 24 holes with three webs in each hole were used. Also covered are dielectric strength, arc resistance, Bashore rebound, and maintenance aging tests on the various materials that have been successfully molded.
