Title: Adjustable valve servo intensifier - has control valve with plunger to vary pressure in working chamber
Inventor: THOMAS ALFRED WILLIAM
IPC: B60T13/16
Filed: 1974-03-19
Abstract: The servo intensifier has an adjustable servo valve device which acts on a piston in an operating chamber of a servo-motor. The servo valve is operated according to the control pressure of an incompressible flow medium in a control chamber, varied according to the movement of an input control component and an output control component connected with the piston in the control chamber. The input control component is so arranged that on drop in the working pressure, it acts on the output control component so that operation of the piston is possible. The control valve has a valve plunger to vary the medium pressure in the working chamber while the plunger is exposed on one side to the pressure in the working chamber and on the other side to the pressure in the control chamber.

Title: Fishpond water oxygenation - by mixer, tubular coil and screen deck cylinder for water/air mixture at different inlet pressures
Inventor: LUECKE ROLAND DR ING
IPC: A01K63/04
Filed: 1974-04-27
Abstract: Circulating water for use in intensive pisciculture can be enriched with oxygen in a mixing chamber in which the water and the air arrive at different pressures. Water containing the air in finally distributed bubbles is passed through a tubular coil, contng. turbulators and then descends through perforated screen decks in the middle of the cylindrical coil support structure. The long residence time ensures a high aeration efficiency. The volume-to-air throughput ratio of this system is much higher than in an aerator inside a pond. It also has no detrimental effect on the heat balance of a pond.

Title: Safety shut-off valve for motorcar hydraulic brakes - is designed to isolate leaking wheel cylinders automatically or manually
IPC: B60T11/32
Filed: 1974-07-17
Abstract: The isolating valve has a central hollow cylindrical body with outside threads at each end over which the inlet and outlet bodies are screwed.

Title: Measuring flowing liq. pH value - detecting variation in time of signal voltages in similar measurement circuits
Inventor: BOCK REINHARD
IPC: G01N27/416
Filed: 1976-04-17
Abstract: The measurement method for the pH value of a flowing liq. compares variations of signals in measurement circuits. Smallest variations are made ineffective. One measurement circuit has at least one measurement electrode and a reference electrode, in which a signal voltage corresponding to the pH value is generated. At least two similar measurement circuits are used. Variation in time of signal voltages in individual measurement circuits is detected. When absolute values of these changes in the circuits differ from each other during a specified time interval, the circuit with the smallest variations is made ineffective.
