Title: Corrosion measurement system temp. compensation appts. - has sacrificial probes inserted into atmosphere to determine corrosion losses by measuring changes in probe resistance
Inventor: SCHMIDT THOMAS RUPERT
IPC: G01N17/00
Filed: 1980-07-23
Abstract: Sacrificial probes are inserted into a corrosive atmosphere at significant points, and corrosion-related losses from these probes are measured by monitoring changes in probe resistance. By comparing these changes to a reference probe, accurate determinations of corrosion are made. The automatic temp. compensate appts. removes essentially all degrading effects of changes in temp. on the corrosion measurement system, by obtaining a reference signal which varies proportionately with temp. Instantaneous and extended temp. changes are compensated by subtracting the reference signal due to temp., variations from the uncompensated system output signal due to the combined effects of corrosion and temp.

Title: Control device for anti-blocking system
Inventor: GOEBELS HERMANN-JOSEF ING GRAD
IPC: B60T8/88
Filed: 1981-01-23
Abstract: A control device for an anti-blocking system is proposed, which device switches over to unimpeded brake pressure application mode in the event of a fault in the device in order to maintain the braking capacity of the vehicle under any circumstances. However, since the driver has usually initiated full braking when the anti-blocking system is operating, he would be surprised by a sudden switch over to full braking effect. Therefore, a safety circuit (28) with timing element (35) and clock generators (36 and 37) is provided which in such a case switches over to full braking pressure only in a delayed fashion and notifies the driver of the new situation visually (monitoring light 46). The driver then has time to adapt to the new system. The control device for an anti-blocking system is intended for motor vehicles, in particular for passenger cars. <IMAGE>

Title: "Method for delivering a fluid, and hermetically enclosed pump-motor unit for implementing the method"
Inventor: GRUBER FRANZ
IPC: F25B15/02
Filed: 1981-03-16
Abstract: In absorption heat pumps, a refrigerant-rich solvent is delivered by a pump. The fluid drawn in from the absorber is almost in the boiling state and begins to boil on the suction side of the pump in the event of small temperature fluctuations. The vapour produced results in unwanted cavitation. This is prevented by the pressure of the fluid being increased on the suction side of the pump, preferably by compressing the fluid by means of the rotor (7) of the motor (2) and feeding it to the pump (1) via the former. <IMAGE>
