Abstract: A system for supplying compressed air to a pneumatic network includes a load compressor, an air supply and a power shaft driving the load compressor. The system also includes in an air outlet of such load compressor, a connecting channel connected, on the one side, with a channel connected with the pneumatic network and, on the other side, with an air discharge conduct towards an exhaust nozzle. Air flow rate bleed valves are controlled by a processing unit via servo-loops as a function of the pressure sensors and the speed sensor.

Abstract: The invention relates to a device for starting a gas turbine, comprising an initiation system able, on command, to rotate said gas turbine. The starting device comprises means for receiving information representing the rotation speed of the gas turbine, means for calculating a set torque value according to said information representing the rotation speed of the gas turbine, and means for transmitting said set torque value to the initiation system, and the means for calculating the set torque value are suitable for making a comparison of the information representing the rotation speed of the gas turbine with a predetermined speed profile and calculating the set torque value from said comparison.

Abstract: The invention relates to a safe support device for a syringe, said support comprising a support sheath for the body of a syringe, and safety means which comprise an inner sheath suitable for sliding relative to said support sheath between a waiting retracted position, in which said inner sheath is substantially retracted inside said support sheath, and an active protection position, in which said inner sheath projects from said support sheath. The inner sheath has a free end portion formed by a flexible end-piece. The invention also relates to an assembly comprising such a safe support device and a syringe having a body, a piston and a needle disposed at one end of said body.

Abstract: The invention relates to a starting device for an auxiliary power unit (10), comprising a control unit (32) of the power supply of a starter motor (12), said motor (12) being suitable to be supplied with power by a supply network (16) and configured to drive a revolution of the auxiliary power unit (10), the control unit (32) being suitable to receive an item of information representative of the speed of rotation of the auxiliary power unit (10) and control of the power supply of the starter motor (12) by the control unit (32) being dependent on said item of information representative of the speed of rotation. The device is characterised in that the control unit (32) is suitable to receive an item of information representative of the voltage of the power supply network (16) and in that control of the power supply of the starter motor (12) by the control unit (32) is dependent on said item of information representative of the voltage.
