Title: Improved apparatus for automatically controlling water level in steam boilers
IPC: F22D5/00
Filed: 1921-12-20
Abstract: 194,803. Martin, J. I. Dec. 20, 1921. Feed - water, controlling.-A doublebeat valve D controlling the feed supply to a boiler A is operated by a diaphragm E subjected on the under side to the constant pressure in the feed pipe and on the upper side to the varying pressure in a pipe K which is connected to the top of a vertical pipe G opening into the boiler at the normal waterlevel therein. When the water-level falls, the vertical pipe G is filled with steam, thus increasing the pressure on the upper side of the diaphragm and causing the valve to open. When the water-level rises, the vertical pipe G is filled with water. A chamber M at the top of the pipe K prevents undue rise and fall of the water above the diaphragm due to movements of the diaphragm.

Title: Hydropneumatic Suspension and Damping Devices having Level Regulation for use in Motor Vehicles
IPC: B60G17/044
Filed: 1968-07-18
Abstract: 1,185,279. Vehicle suspensions; levelling. ADAM OPEL A.G. 18 July, 1968 [6 Sept., 1967], No. 34231/68. Heading B7D. [Also in Division F2] In a self-levelling hydropneumatic vehicle suspension unit, level-regulating liquid flow between gas-loaded liquid reservoirs 15, 27 and a working cylinder 1 is controlled by a pair of slide valves 34, 40. These valves concentrically surround the rod 24 of a working piston 23 and control fluid transfer ports leading from the cylinder to the respective reservoirs. When the piston 23 oscillates in its cylinder 1, downward piston movement forces liquid from the cylinder space surrounding the piston rod 24 past a non-return valve 39 into a gasloaded reservoir 15 in a tube 2 surrounding the cylinder; and upward piston movement causes liquid from a reservoir 27, consisting of the hollow interior of the piston-rod and a gasloaded chamber below it, to open a non-return valve in the piston and replenish the pistonrod-surrounding space with liquid. In this way dynamic load variations, when the associated vehicle moves, cause fluid to be pumped from reservoir 27 to reservoir 15, building up the pressure in the latter. On an increase in static load on the piston it advances substantially into the cylinder, i.e. upwardly, and a normally compressed spring 44 surrounding the pistonrod relaxes and allows a spring 41 to raise a slide 40 which also surrounds the piston-rod. This covers the outlet 45 leading by way of the valve 39 to the high-pressure reservoir 15 and uncovers a smaller outlet 42 which communicates with the reservoir 15 by way of the screw threads 43. This opens a restricted flow path between the high pressure liquid in the reservoir 15 and the main cylinder 1, and the consequent rise in pressure in the cylinder returns the piston towards its original position. On a reduction in static load on the piston, a slide 34 surrounding the piston-rod just below the piston 23 moves to cover the normally open port 32 and uncover a smaller port 37 which communicates via the screw threads 38 with the low-pressure reservoir 27, thereby reducing the pressure in cylinder 1 and so returning the piston towards its mean position. In addition to the gas-loaded liquid reservoirs 15, 27 a third gas-loaded liquid chamber 16 is provided to serve as a regulating chamber.
