The axial flow valve, or Thayer valve, is a brass instrument valve design patented in 1978 by American inventor Orla Ed Thayer. [1] Designed with assistance from instrument maker Zigmant Kanstul, it was originally intended to replace the traditional rotary valve on the French horn , but instead revolutionized the design of trombone valve ...

Greer Spring is a first magnitude spring located in the southeast portion of the Ozark Plateau, in Oregon County in south-central Missouri within the boundaries of the Mark Twain National Forest. The spring is the second largest spring in the Ozarks , with an average discharge of 360 cubic feet (10 m 3 ) of water per second. [ 1 ]
When used as intended, the ground pin of the 3-wire receptacle is to be connected to a grounded cover screw, or to an external ground. In 1969, Underwriters Laboratories mandated three-prong plugs on major appliances for safety. [7] At that time, only half of the receptacles in US homes were three-prong. [7]
A closely related but different design is the so-called "pin tip plug" and matching "pin tip jack". Its plug design resembles the banana plug but without the spring on the male pin; instead, it relies on spring action in the female jack, or tightly machined tolerances, to ensure good contact. The diameter of the male pin is 2 mm.
The average flow of 470 cubic feet (13,000 L) of water per second [1] from Big Spring constitutes the second-largest tributary of the Current River. The spring is by far the largest spring in the Ozark Plateau region. The only two springs in the Ozark region that approach the size of Big Spring are Greer Spring and Mammoth Spring. The maximum ...
A basic stepping switch is an electrically operated rotary switch with a single (typically input) terminal, and multiple (typically output) terminals. Like other typical rotary switches, the single terminal connects to one of the multiple terminals by rotating a contact arm, sometimes called a wiper, to the desired position.
