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.
System provides rapid command sync acquisition between widely separated transmitter-receivers. It is based on a rapid, automatic range-adjustment approach rather than the time-consuming cycle slipping or stepping techniques of conventional phase-locked loops.
System makes use of diverging duct walls for conducting the light from entrance slips to the conductors by means of multiple reflectors. This system simultaneously records, photoelectrically, the intensities of several closely spaceed narrow wavelengths in the ultraviolet and infrared areas of the spectrum.
Measurement of great circle patterns requires rotation in azimuth with discrete rotation in elevation. This technique eliminates a set of slip-rings and rotary joints and permits the use of larger models since only continuous azimuth rotation is required.
Subsonic expansion tube evaluation as device for studying particle drag in subsonic compressible slip flow
Ball bearing lubrication simulation by rolling disk apparatus, emphasizing surface slip and related thermal effects alterable by geometric expansion
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.
Two-stage polyphase generator is usable as induction motor operable over range of speeds while powered from constant frequency source. It requires neither slip rings nor special adjustable-frequency power supplies or external reactive sources.
Connector is modified by machining the cone from one end before the fitting is bored to accommodate a metallic-filament type of slip-in filter. Thus, when surface of the cone is damaged, only the cone needs replacement.
Energy dissipation and damping effects on aluminum cantilever beams in air and vacuum vibration tests, and slip in cantilever beams with either nonsymmetric or multiple interfaces
Design and testing of torque motor driven bearing assembly with integral slip ring unit for experimental tactical communications satellite
Statistical behavior steady state phase error and time to cycle slip for phase lock loops
Phase noise and cycle slip optimization of steady state digital data transition tracking loop used as bit synchronizer in phase-coherent receiver
Water and alkali metal boilers, predicting helical-flow-promoting inserts effect on pressure drop penalties by constant slip model
System detects defects of .051 cm in diameter and larger. System incorporates scanning head assembly including boot enclosed transducer, slip ring assembly, drive mechanism, and servotransmitter. Ultrasonic flaw detector, prototype recorder, and special recorder complete system.
Chair holds man in semistanding posture enabling astronauts to work comfortably with minimum restriction in weightless environment. Seat, angled at 130 deg to back support, twists and swivels up to 20 deg in all directions but forward. Two flexible thigh clips prevent occupant from slipping off.
Rarefied gas flow through long square tubes, solving continuum differential equation with noncontinuum slip boundary conditions
LiF and MgO high purity single crystals plastic deformation geometric characteristics, discussing nucleation probability on different slip planes
