Abstract

1373813 Detecting the presence of bubbles in a liquid JOSEPH LUCAS (INDUSTRIES) Ltd 18 April 1972 [23 April 1971] 10920/71 Heading G 1A In an apparatus for detecting the presence of bubbles in a liquid flowing through a tube, a housing, having a key hole shaped slot 13 whereby the housing may be mounted on the tube by way of the elongated outer part 13b to position the tube in the inner circular part 13a, contains a lamp 14 and a photo-transistor 15 which are diametrically disposed within the housing with respect to the circular inner part 13a. The housing may consist of two parts Figs. 2, 3, 4 (not shown) which are made of synthetic resin material and which may be held together by screws or by means of a circlip.
