What is the meaning of a coupler?

What is the meaning of a coupler?

Definition of ‘coupler’ 1. a link or rod transmitting power between two rotating mechanisms or a rotating part and a reciprocating part. 2. music. a device on an organ or harpsichord connecting two keys, two manuals, etc, so that both may be played at once.

What is a coupler and what does it do?

A two-part device called a coupler lets you use different decorating tips with the same bag of icing, creating several designs with the same color and consistency.

Is there a difference between a coupling and a coupler?

Are they interchangeable? Merriam-Webster dictionary doesn’t seem to think so. Among its definitions, a coupling is “a device that connects two parts or things”…. but, search coupler and you will find no reference for anything mechanical power transmission related.

What is coupling in psychology?

Coupling theory is the idea that some behaviors are “coupled”–a behavior is linked to a specific context. A person’s behavior is affected by his personal history and environment.

What is coupler in civil engineering?

Mechanical Couplers are the cylindrical element that connects the two rotating edges of reinforcement bars, also known as an alternative to lapping rebars. The grade of the coupler should be equivalent to the reinforcement bars which ensures the maximum transmission of the load stresses from one bar to another.

What are couplers used for in RF?

RF & Microwave couplers are passive devices that are used to sample high frequency signals. Couplers have many applications and are used for sampling signals, signal injection, signal generation, used to measure incident/reflected power to determine VSWR and have a number of other applications.

What is directivity of a coupler?

Directivity is a measure of how well the coupler isolates two opposite-traveling (forward and reverse) signals at the coupled port. It means that better the directivity of a coupler, there will be less leakage from the reflected power to the coupled port and hence the forward power measurement will be more accurate.

What is the difference between socket and coupling?

Full Coupling is used for connecting small bore pipes. It used to connect pipe to pipe or pipe to swage or nipple. A socket weld full coupling is used to join small bore plain end pipes where the pipe spec requirement is socket weld. A threaded full coupling is used to join small bore pipes with threaded ends.

What is a coupler fitting?

Coupling & Adapter Fittings – Pipe couplers slip over the outside of two pipes to connect them, usually permanently. A coupling can be a reducer, or reducing coupling, meaning they reduce flow by joining a larger pipe to a smaller size. Adapters are used when connecting two pipes of different types.

What is a coupler in a car?

A coupler, or coupling, is a device for joining rail vehicles in a train. The semi-permanent coupler has a vulcanized metal-rubber articulation that allows relative movement between the cars.

What does coupler mean?

Definition of coupler. 1 : one that couples. 2 : a contrivance on a keyboard instrument by which keyboards or keys are connected to play together.

What is directivity in a coupler?

The Directivity in a coupler is the ratio between the input signal at the coupled port and the unwanted reflected signal at the coupled port. It is a measure of how well the coupler isolates two opposite-traveling (forward and reverse) signals at the coupled port. This might sound confusing, so let me illustrate this using a diagram.

What is an Universal Coupler?

A universal coupler is a specialized rotary joint used to allow a rotating split shaft to deflect along its axis in any direction. In other words, the universal coupler would allow a boat drive shaft exiting a gearbox standing dead level to drive a propeller orientated at 22° from horizontal. This flexibility is achieved by constructing the joint with two U-shaped yokes joined by a cross-shaped hub.

What is a RF coupler?

An rf directional coupler is a measurement instrument that consists of a line section, inserted in one of the following rf-lines: Coaxial lines, waveguides, strip-lines, tri-plate-lines, wirelines and so on. This line section is normally inserted between a transmitter (or generator, or amplifier) and its load.
