Abstract: 1,176,819. Method of producing a spray. R. S. BABINGTON, A. E. YETMAN and W. R. SLIVKA. 29 Dec., 1967 [29 Dec., 1966], No. 59050/67. Heading B2F. A method of dispersing liquid into a gaseous medium comprises the steps of providing a smooth surface having at least one aperture therein, causing a flow of liquid onto the surface with sufficient energy to cause the liquid to flow in a film over the aperture, and supplying gas to the aperture under a pressure above ambient, whereby the film is stressed to the point of rupture, the gas carrying minuscule particles of the liquid into the gaseous medium in a spray having the characteristics of natural fog. In a preferred form the liquid is supplied at the top of a hollow tube whereby the liquid is further stressed by acceleration due to gravity, the aperture being positioned at the point of maximum stress. The aperture may be circular, oval or preferably an elongated slit. The materials employed depend on the intended application, thus for producing a humidifying fog, water, air and glass surface are used and this is the preferred application. For fuel atomization the materials may be kerosene, air and a stainless steel surface, while for metal processing such as rolling, the materials would be oil, hot air, and a copper surface.

Title: Video signal transmission and receiving apparatus using optical paths
IPC: H04N5/775
Filed: 1978-12-06
Abstract: To transmit a video signal from an auxiliary video source 10, such as a television game, a video tape recorder or a television camera, to a television receiver 16 for display on the receiver instead of a video signal broadcast from a primary source and received via an aerial or cable, the video signal is modulated onto a light beam 24 which is transmitted by free air or by a fibre optic cable. At the television receiver 16, the video signal is recovered from the light beam 24 and displayed. The recovered video signal may be supplied directly to a video-frequency input (66-Figure 3, not shown) of the receiver 16 or may be used to modulate an RF signal which is supplied to an RF input 54 of the receiver 16. The use of a light beam for transmission, rather than electrical transmission via a coaxial cable or the like as in the prior art, greatly reduces the generation of electromagnetic interference. <IMAGE>
