Abstract: A method for changing a mould of a moulding device, includes at least the following steps for dismounting a mould: (a) controlling fixing elements in order to release each mould half (20), (b) joining the mould halves together in order to form a single transportable sub-set, (c) opening mould carriers (14) from their closed position during steps (a) and (b) in order to extract, with a translational movement, the sub-set arranged in a reference position, and (d) removing the sub-set as a single unit from its reference position, from between the mould carriers.

Abstract: Hollow body extending along a principal axis and having a neck provided with a first relief suitable for allowing a predetermined angular indexing of the hollow body around its principal axis with respect to a device for gripping the hollow body. The neck having a second relief, axially offset with respect to the first relief, suitable for allowing a predetermined angular indexing of the hollow body around its principal axis with respect to a second gripping device superimposed on the first one.

Abstract: A forming method, in a mold fitted with a wall forming a cavity, of a container from an intermediate container including at least one lateral protrusion projecting toward the exterior of the container. The method includes a boxing operation of pushing back the lateral protrusion in order to form, by turning it around an articulation zone, a hollow reserve projecting toward the interior of the container and a local cooling operation, after turning the protrusion over, of sweeping a circulation fluid over the articulation zone.

Abstract: Device for forming containers from blanks made of plastic material, having a mold provided with a wall defining a cavity intended to receive the blank; a boxing insert mounted movably with respect to the mold between a retracted position in which the insert is retracted into the wall, and an extended position in which the insert projects from the wall toward the interior of the cavity; a plate, on which the insert is rigidly fixed; a support on which the plate is removably mounted; and a system for the quick attachment of the plate to the support.

Abstract: A forming method, in a mold fitted with a wall forming a cavity, of a container from an intermediate container including at least one lateral protrusion projecting toward the exterior of the container. The method includes a boxing operation of pushing the lateral protrusion by an insert movably mounted with respect to the mold between a retracted position in which the insert is retracted into a recess formed in the wall and a deployed position in which the insert protrudes with respect to the wall, in order to form, by overturning, a hollow reserve projecting toward the interior of the container. Also included is an operation to pressurize the intermediate container, including, prior to the boxing operation, injecting a fluid under pressure into the intermediate container; and a local pressurization operation, prior to the boxing operation, of injecting a fluid under pressure into the volume defined in said recess between the lateral protrusion and the insert.

Abstract: A forming method, in a mold provided with a wall forming a cavity, of a container from a blank, which includes a boxing operation of pushing back the material of the blank by an insert movably mounted with respect to the wall of the mold between a retracted position in which the insert is retracted into the wall, and a deployed position in which the insert protrudes with respect to the wall, in order to form on the container, by pushing back, a hollow reserve projecting toward the interior of the container. Additionally, a local pressurization operation is performed, after formation of the hollow reserve, of injecting a pressurized fluid between the insert and the hollow reserve.

Abstract: Device for depositing a coating on an internal surface of a container, of the type in which the deposition is carried out by means of a low-pressure plasma created inside the container by excitation of a precursor gas by microwave-type electromagnetic waves.

Abstract: A container-treatment method, of the type in which the container (12) is disposed inside a chamber (16) which defines a cavity (18) outside the container (12) and which is connected to a Vacuum pumping circuit (50), the interior of the container (12) being connected to the pumping circuit (50). The method includes a preliminary pumping step (E1) which is followed by a treatment step (E2). The preliminary step (E1) includes the following successive phases, namely: an external pumping phase (P1) which produces a drop in the pressure inside the cavity (18) only; and an internal pumping phase (P2) which produces a drop in the pressure inside the container (12) only. A machine used to implement the method is also disclosed.

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.

Abstract: The invention concerns a rotating machines for treating containers. When a workstation Pi enters (&thetas;1) a treatment zone, the treating equipment automatically consists of a stationed part (Eq 1) and a common part (Cj) which is mutually coupled with another workstation which is not located at the same time as the station (Pi) in the working zone (3). The same arrangement is used for a control equipment.

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
