  • Patent number: 11377382
    Abstract: Device for forming a glass article, including a forming mold for receiving a glass blank, and a gas injection device with a blowing head intended to be received in the mouth of the blank, the gas injection device including a pressurized gas inlet, a first injection channel connecting the pressurized gas inlet to at least one outlet port opening into the inside cavity, through a first control solenoid valve, with a first pressure sensor and a first temperature sensor, a vent channel connecting the inside cavity to the outside air, the vent channel being equipped with a second pressure sensor and a second temperature sensor, an electro-pneumatic control unit being configured to control the first control solenoid valve according to the pressure measurements and temperature measurements.

  • Patent number: 4836743
    Abstract: The purpose of the invention is a cross flow fan comprising an convergent inlet (2,3,10), an impeller (1) or rotor provided with blades and a divergent (4) delimited by a downstream face (12) of the scroll element and a downstream face (9) of the cross-head element. The inlet and divergent delimit two narrowing longitudinal passages (13, 14). With respect to a reference system of perpendicular axes x and y, the origin of which is located on the axis of rotation of the impeller (1) and whose abscissa X axis is parallel to the downstream face (9) of the cross-head element, it features:an upstream leading edge (6) of the cross-head element describing an angle included between 290.degree. and 330.degree. at a distance from the impeller or an air gap (13) included between 2 and 8% of the outside diameter De of the impeller,a face (7) of the cross-head element describing an angle, the apex of which is one and the same with upstream leading edge (6) of the cross-head, included between -20.degree. and 60.degree.
