Gas transmitting body for use in bubble shearing

Abstract

Abstract Method and apparatus for bubble shearing are disclosed in which nascent bubbles are formed by flowing gas through the very small capillary openings of a gas diffusing surface into a moving liquid that shears the nascent bubbles off as it moves past the capillary openings. In the apparatus disclosed, the gas diffusing surface forms one wall of a liquid transmitting slot through which the shearing liquid flows as it shears off fine gas bubbles. A gas transmitting body or gas "bar" for use in the bubble shearing apparatus is disclosed. The gas transmitting body has at least one wall with a plurality of gas transmitting passages extending therethrough terminating in capillary openings. The maximum size of the capillary openings is given, as well as the maximum distance of the most remote capillary openings from an edge of the gas diffusing surface defining one boundary thereof. Improved and preferred values for these parameters are also given. Other structural features of the gas transmitting body are disclosed. A rapid and efficient method of fabricating the gas transmitting body of this invention in which the plurality of gas transmitting passages through the body is defined by discrete tubes embedded in the wall of the gas transmitting body as a matrix is also disclosed. Suitable and preferred methods of applying binder to form the matrix, as well as methods of positioning the discrete capillary tubes to be embedded in the matrix, are disclosed.
