| This invention is directed to a spray device for spraying two or more components. The two or more components are maintained separated in the spray device and are mixed post atomization. This invention is also directed to a gravity fed spray gun and a system for spraying two or more components. This invention is further directed to a kit for converting an existing conventional single-component spray gun typically used for spraying a single component to a two-component spray gun for spraying two components. | ||||||

| 40 | METHOD AND DEVICE FOR LIQUID LEAKAGE INDICATION | EP96935709.0 | 1996-10-16 | EP0856150A1 | 1998-08-05 | Persson, Lars-Anders |
| Method and device for indicating movements of gas bubbles in a liquid, droplets of liquid in a gas or a level of liquid, the liquid or the gas forming a medium in a conduit (15) or a container. Microwave signals of a predetermined frequency are transmitted through a section (G) of the conduit (15) or the container (16) that is pervious to microwaves toward said medium, and microwave signals reflected from the medium are received. Received microwave signals are then utilized to indicate presence of gas bubbles, droplets, or a level of a liquid moving in said conduit (15) or said container (16). Said conduit (15) is designed with a section (G) that is pervious to microwaves, and a microwave transmitter (S) is provided to transmit microwave signals towards said section (G). A microwave receiver (M) is provided to receive microwave signals that are reflected from the medium, and said microwave receiver (M) is operatively connected to a detector (6). | ||||||
