Abstract: A method of measuring the wall temperature of a container blank, including the following operations: inserting a temperature probe into the blank in motion, upon completion of the operation of heating the blank in an oven; maintaining the probe in the blank in motion for a predetermined time; making a temperature measurement by the probe maintained in the blank without contact with the inner wall of the blank; and storing the temperature or the temperature profile thus measured.

Abstract: The electrical power supply to a magnetron (M) is regulated as a function of an instantaneous microwave power setpoint by: predetermining and storing (20) a value (?) for the electrical efficiency of the magnetron; inputting (19) a setpoint mean microwave power value, and converting it into a low frequency setpoint instantaneous power signal that is sampled at high frequency; measuring (8, 9) and sampling the instantaneous values of anode current and of the high voltage fed to the magnetron; calculating (10) the difference at a sampling instant (n) between the setpoint instantaneous microwave power and the product of the current multiplied by the high voltage multiplied by the efficiency; determining an instantaneous microwave power value at the consecutive sampling instant (n+1) that is corrected as a function of a predetermined regulation relationship that is valid at said instant (n+1); and converting it into an analog signal representative of the corrected instantaneous microwave power for powering the ma

Abstract: Method for controlling a high-voltage power supply generator for a magnetron (16) for producing a cold plasma inside a hollow body in order to carry out the deposition of a boundary layer within said hollow body, characterised in that it comprises selecting (E2) a generator operation mode from a plurality of operation modes (MODE 1, MODE 2, MODE 3), modifying the operation mode (MODE 1, MODE 2, MODE 3) of the generator by varying at least one coefficient ((a, b, c); (a1, b1, c1)) defining a maximal power Pmax of the waveform of the supply power of the magnetron (16) according to a set average power Pmoy of the magnetron (16), the magnetron (16) supply waveform being repeated recurrently with a cyclic conduction ratio Th depending on the set average power Pmoy and/or on the maximal power Pmax.
