Abstract: A container capping control device for a machine may include at least one capping head adapted to place a closure member on a container. The capping head may include a driving motor. The device may include a calculation unit, a graphical man-machine interface and a plurality of capping programs adapted to be parameterized by means of the interface. A capping program may be adapted to control the capping head in accordance with at least one phase of rotation of the closure member when the capping program is executed by the calculation unit.

Abstract: A device for controlling an electric motor measures the current Im drawn by the motor and the torque Cm supplied by the motor. It includes a power supply 4 for the motor and an initialization unit 16 capable of generating a torque set point Cc and of receiving and processing information relating to the current Im and the torque Cm to deduce therefrom a relationship between the set point Cc, the torque Cm and the current Im in order to be able to determine the torque Cm from the set point Cc and the current Im.

Abstract: The turbine which generates overpressure for a breathing gas is controlled by detecting recurring variations in the operation of the turbine and correspondingly modifying the control signal which is set to a level which determines the overpressure of the turbine, thereby modulating the overpressure supplied by the turbine.

Abstract: An apparatus for artificial ventilation for assisting the volumetric breathing of a patient having a demand valve connected between a source of supply of gas and a spontaneous breath tube. This demand valve comprises a reference chamber connected to an expiration tube and a user and to the output of a Venturi tube connected by its inlet to the source of supply of gas. A generator of increasing pressure is provided for transfer of a complementary flow of gas, this generator being connected by its inlet to the source of gas supply and opening out in the upstream end of the Venturi tube assisting the user's exhalation.

Abstract: The device comprises a respiratory gas generator including means for establishing, during an inspiratory stage and in a supply pipe leading to an inspiratory orifice associated with an expiratory valve, a pressure of a respiratory gas which is substantially constant irrespective of the flow of inspiratory gas. The means for establishing a substantially constant pressure comprise an ejector of the convergent/divergent type which opens onto said supply pipe. In contrast to ventilators having multiple modes of ventilation which are usually intended for patients subjected to intubation or tracheomatization, the device is intended for patients who are connected to the device through a simple mask covering the nose and mouth, a nose mask or a mouthpiece.

Abstract: A respirator is provided for the treatment, particularly in the home, of persons suffering from respiratory insufficiencies. The respirator comprises a reciprocating linear electric motor compressor having a gas intake orifice connected to atmosphere for example, a compressed gas discharge orifice connected to a respiratory mask, a piston, a spring acting on the piston, and an electromagnet for moving the piston against the action of the spring to supply compressed gas to the mask via the discharge orifice. A thyristor pulse generator is controlled by a clock to provide pulses to the electromagnet to define the insufflation time. The compressor operates only during the insufflation time.
