Patent DE-2342498-A1 (DE)
Title: Hydraulic directional control valve - has a five port three position valve which provides constant output flow rate independent of loading conditions
Inventor: HERRMANN WALTER
IPC: F15B13/04
Filed: 1973-08-23
Abstract: A hydraulic directional control valve arrangements provides a 5 port/3 position operational mode such that flow regulation to cylinders may be achieved independently of loading conditions. Two main cylindrical spool valves are located in parallel in a valve block with interconnected passages. Each spool valve is controlled by input stages in the form of compound spool units. Each input stage consists of a fixed hollow spool with porting and an inner pressure actuated two-land spool with spring bias for the null position. A spring loaded shut-off valve is located between flow input and the input stages. In operation the flow orifice to the load is maintained in a balanced condition to provide a constant flow rate to the load. Check valves fix the overall operating level of the system.

Title: Alarm system with DC quiescent loop current monitoring - uses constant current regulator with two types of alarm
Inventor: GEIGER KLAUS ING GRAD
IPC: G08B29/06
Filed: 1974-03-27
Abstract: Alarm systems for monitoring doors, windows, safes etc., often have separate indication for these alarms and for alarms generated by opening the cover of a loop connecting junction box. Where this is done with different currents, the lengths of loops becomes critical. With this proposed system it is achieved by using a constant current source to feed a current through the cover contacts, a series resistor, and the alarm contacts in parallel with a resistor. These resistors are proportioned for the alarm current detector so that when an alarm contact is opened the parallel resistor is included in the loop and the current is reduced by approx. half. If a cover contact opens the current drops to nearly zero. The constant current regulator uses six diodes, two transistors, two resistors and an NTC resistor.
