A synchronizing separator circuit used for a television receiver which has an amplitude separator circuit and a frequency separator circuit well adapted for simple construction and circuit integration.

The coupler includes a rotary capacitive coupler.

The combined reactive coupler includes a magnetic coupler (12) and a capacitive coupler (13).

An integrated coupler may vertically integrate a hybrid coupler and a directional coupler.

A generally planar T-shaped separator (45) replaces the conventional separator in a diffusion transfer processor (10).

A small cyclone separator (12) is coupled to the scroll separator and connected in a closed loop system with the scroll separator for continuous recycling air therethrough.

A coupler/coupling ring assembly comprises a coupler and a coupling ring that is removeably engageable with the coupler.

A coupler/coupling ring assembly comprises a coupler and a coupling ring that is removeably engageable with the coupler.

A coupler/coupling ring assembly comprises a coupler and a coupling ring that is removeably engageable with the coupler.

The or each coupler is tubular in section.

A fourth coupler is coupled to the second output of the first coupler and to the second output of the second coupler.

A directional coupler with two sensing conductors and a basic coupler and a supplementary coupler corresponding to them.

Thereby, the residue of the separator will be diluted.

The coupler is preferably a Y-junction coupler, but can also be a multi-branch waveguide coupler or a waveguide directional coupler.

A third coupler is coupled to the first output of the first coupler and to the first output of the second coupler.
