Abstract
7964. Nesbit, D. M. April 2. Stuffing-boxes, substitutes for.-A fluid-operated valve suitable for use in a low-pressure steam heating-system in which the return main is maintained at a pressure below that of the atmosphere is shown in Fig. 2. The valve g is connected to a flexible diaphragm h, which divides a casing l into two compartments, of which one communicates with the atmosphere and the other can be put into communication with the atmosphere or with the return main of the system.
