摘要:
The invention relates to a machine for descaling cells (3) of a cellular runoff body (2) used in an air-water exchanger, characterized in that it comprises at least one tool (6, 7) having an active tip (6a, 7a) and mounted on a frame (1) so as to be mobile between two positions in one direction common to all of the tools (6, 7) supported by the frame (1), the active tip (6a, 7a) of said tool being supported by the end of a rod (13) of a cylinder (11), the body (12) of which is mounted so as to be mobile relative to the frame (1) along the axis thereof, a piston (23) rigidly connected to the rod (13) and defining, in the body, a first chamber (26) which is constantly connected to a source of pressurized fluid and to a second chamber (27) through which the rod (13) passes, is in communication with the first chamber (26) as long as the rod (13) is at least partially retracted into the cylinder body (12) and insulated from the latter, and is connected to the exhaust when the rod (13) is in an end extension position outside the body (12).

摘要:
A method of in situ scale removal from a heat exchange body suspended in a wet cooling tower. At least one air blast is generated by a generator implementing controlled expansion via a nozzle of a mass of compressed gas in a nozzle towards a zone of the body. The generator is opened at a distance from the zone, and the method repeats the operation after moving the generator under the body outside the zone.

The invention relates to a device for extracting a liquid (14) contained in a container (12, 13, 15) of non-brittle material such as a container containing a liquid or pasty cosmetic or food product. The device comprises two wheels (1, 2) rotating about parallel axes (AX1, AX2) and separated from each other by a gap (E), together with motor means (3) for driving the two wheels (1, 2) in rotation in opposite directions. At least one of the wheels (1, 2) includes spikes (7, 11) projecting radially from an outer base diameter of the wheel (D1, D2) and engaging in corresponding recesses in the other wheel (1, 2; 21). The device serves simultaneously to compress and to pierce the containers (12, 13, 15) when they pass through the gap (E) between the two wheels.

摘要:
A method for using photoluminescence to identify defects in a sub-surface region of a sample includes performing a first probe of the sample. A first data set, based on the first probe, is produced indicating defects located primarily in a surface layer of the sample. A second data set, based on a second probe, is produced indicating defects located in both the surface layer and a sub-surface region of the sample. The first data set is subtracted from the second data set to produce a third data set indicating defects located primarily in the sub-surface region of the sample. The first data set may optionally be normalized relative to the second data set before performing the subtraction. The first and second probes may advantageously be performed using a first laser and a second laser, respectively, having different wavelengths from each other.
