  • Control system and method for propeller-speed overshoot limitation in a turbopropeller engine
    Patent number: 11927143
    Abstract: An electronic control system (35) for a turbopropeller (2) having a gas turbine engine (20) and a propeller assembly (3) coupled to the gas turbine engine (20), the control system (35) having: a propeller control stage (35a), implementing a closed loop control for controlling operation of the propeller assembly (3) based on a scheduled propeller speed reference (Nrref) and a propeller speed measure (Nr); a gas turbine control stage (35b), implementing a closed loop control for controlling operation of the gas turbine engine (20) based on a scheduled reference (Ngdotref) and at least a feedback quantity. The control system (35) further envisages an auxiliary control stage (35c), coupling the propeller control stage (35a) and the gas turbine control stage (35b) and determining a limitation of the operation of the gas turbine engine (20), if a propeller speed overshoot is detected, with respect to the propeller speed reference (Nrref).

  • Thermostabilized Amadoriases and uses thereof
    Patent number: 11649440
    Abstract: The present invention refers to Amadoriase enzyme protein variants having de-glycating activity and improved thermostability compared to the wild type Amadoriase. The present invention refers also to the use of the thermostabilized Amadoriase as deglycating agent, preferably in the food industry. Moreover, the present invention refers to the use of the thermostabilized Amadoriase as diagnostic and/or therapeutic tools. Preferably, the Amadoriase enzyme protein variants of the invention can be used for determining the level of glycated haemoglobin in a biological sample and therefore for monitoring diabetes.
