Title: Remote control of two separate delivery valves - uses three-way hydraulic slide valves, suitable for oil tankers
Inventor: KASTEL WILHELM
IPC: F16K31/12
Filed: 1974-11-07
Abstract: The required delivery pressure is set by the manually operated control valve, supplied with oil at pressure by the line from the pump and transmits the required control pressure through a pipe to the control chamber of the control valve. If this pressure exceeds the previously set operating pressure the slide moves from one position to a second position. This motion of the control valve actuates the mechanism which opens the valve and at the same time actuates another valve which applies a pressure to the control chamber restoring the first valve to its original position. The delivery valve is similarly controlled by the first valve through the pressure set by the second valve.

Patent DE-2512065-A1 (DE)
Title: Regenerative heat exchanger esp. for gas purification or catalysis - has revolving inlet and outlet distribution valves
Inventor: KATABUCHI KEICHI
IPC: B01D51/10
Filed: 1975-03-19
Abstract: A heat exchanger comprises an upright cylindrical housing, subdivided by a number of radial partition plates into a number of radial compartments, each of which contains a regeneration unit; each regeneration unit is made up of a number of vertical, ribbed or undulating plates, placed in layers so that the undulations are generally at right angles to one another on adjacent plates and constitute meandering flow paths for a fluid; a rotating distribution valve at one end distributes an entering gas through some of these compartments. In a pref. embodiment, the top distribution valve and a bottom collector valve are both mounted upon a vertical tubular shaft which rotates, so that, for example, a hot gas entering at the top of the heat exchanger is distributed by the distribution valve to some of the regeneration units of the total complex, thereby heating up the undulating plates of those units, then passes out through the lower collector valve to leave at the bottom outlet. Simultaneously, another fluid, esp. gas, enters cold, passes through a manifold and so upwards through the remainder of the regeneration units, the upper manifold and leaves through the upper outlet at a higher temp. The heat exchanger thus operates on the principle of a rotary heat exchanger, in which only the valves revolve. Used for purification of waste gases, containing combustible, harmful substances, in catalytic processes, for cooling and dehumidifying gases and for heating gases, etc.
