Title: Peak load turbine generating system - has steam turbine coupled to gas turbine through free wheel arrangement
Inventor: WILD MARTIN
IPC: F01D19/00
Filed: 1973-06-25
Abstract: The system consists of a gas turbine and a steam turbine coupled to a common generator. The steam turbine is fed by steam raised in a waste heat boiler by the gas turbine exhaust.

Title: Control or regulator cct controlled by tele-transmitter - internal reference switched in when input exceeds upper limit
Inventor: JAUSS FRITZ
IPC: G05B11/16
Filed: 1973-11-10
Abstract: With remote tele-transmission units coupled to control or regulator instrumentation circuits, damage can result of the interconnecting transmission cables are damaged become loose or if interconnections are incorrectly made. Facility is built-in to the instrumentation circuitry such that a malfunction of this type, resulting in transmission of an erroneous reference signal, is detected and an internal safe reference value is substituted. The transmitter supplies a reference signal to an operational amplifier that maintains an electromechanical relay closed during normal operation. Operational amplifier compares the reference input with the output of a sensor e.g. temperature or pressure. If malfunction does occur resulting in a maximum level being exceeded, the relay opens and an internal reference value is substituted.
