Quick-release fastener for panels actuated with just one hand. Fastener has no loose parts, does not require mating hardware, and used in blind hole in mating panel. New panel fastener selfcontained unit extending through congruent holes in two panels to be joined. Unit contracts to clamp panels together and expands to release them.
Modified adjustable-grip-length quick-release pin holds two bodies together. Threaded shaft of pin threaded in floating nut to pretension fastener. Pin connects and disconnects rapidly and adjusted to accommodate small differences between thicknesses of nominally identical sets of parts to be attached to each other.
For secure locking and quick release of two objects, this device uses a spring-loaded slotted bolt, locked in position by two retainer arms. When these retainer arms are freed from contact, the bolt is ejected and the objects released.
Joints between two rigid materials lined with velcro fabric can now be broken with ease using any one of several methods. Three such methods are applicable to either hook or loop fabric.
Locking pin can be withdrawn only when stress on the joint is negligible. Pin consists of a forward-pointing sleeve, a spring-loaded sliding handle, and a sliding plunger. Plunger movement controls installation and withdrawal of pin.
Connector concept is based on characteristics of friction between sliding surfaces and consists of two packs of foil strips. Advantages of this connector are - separation is smooth and shock-free, and connector can also act as a seal. Equation for computing tensile load-carrying capability is also given.
Tensile-strength testing apparatus employs a capillary bundle through which a noncompressible fluid is extruded and a quick-release valve system. This apparatus applies the test loads at relatively constant very high strain rates with minimal shock and vibration to the tensile specimen and apparatus.
Triangular aluminum tool kit, filled with polyurethane is constructed to receive various tools and hold them in a snug but quick-release fit as an aid to heavily gloved workers. The kit is designed to allow mounting within easily accessable reach and to provide protection of the tools during storage.
Quick-release coupling for fueling rocket vehicles with cryogenic propellants
Quick-release spring holder secures acoustic sensor to test material surface eliminating adhesive bonding to test material and achieving acoustic emission evaluation from tensile tests. Reusability of sensors reduces test cost.

Remotely-operated, compact quick-release mechanism still functions in event that one or even two attempts to actuate it fail. Contains three independent pyrotechnic devices. Firing of any one of devices sufficient to actuate mechanism. Three pins hold toggle at its base. Retraction of any one of pins allows toggle head to rotate in spherical bearing to free itself from remaining pin or pins. Besides allowing rotation after retraction, bearing also aligns toggle during assembly.
