Abstract

820,743. Photographic developing and like apparatus. HALDEN & CO. Ltd., J. July 19, 1957 [Aug. 25, 1956], No. 26063/56. Class 98(2) [Also in Group XVIII] The level of liquid in a trough of a photographic developing or like apparatus is kept constant by a bird fountain type regulator. Two bores 11, 12 open respectively at the top and bottom of a socket 9 and extend to the bottom of a leg 8. Liquid in the trough is then replenished from a container connected to the socket 9 if its level falls below the end of the leg 8. The container may be a horizontal transparent tube one end of which fits into the socket and the other end is closed.
