The device includes one or more permanent-magnet elements (115) arranged in the water supply circuit (111, 119) so that the soluble calcium precipitates as insoluble crystals. The washing water thus behaves like softer water, reducing or eliminating the use of conventional resin-based chemical softeners. (Ref. Fig. 2)

An apparatus and method of dislodging particles of powder material from the exterior of cartridge filters in the powder recovery unit of a powder spray system. In the powder recovery unit, particles of powder material collect on the cartridge filters as filtered air enters the hollow interior of the cartridge filters and moves toward the open tops thereof. Periodically, the flow rate of the filter...

The fraud detection system uses a resonance device (6) coupled to a contact element (2) of the chip card inserted in the reader for detecting application of an electrical lead (13) used to alter the chip card information. The resonance device has an impedance converter (5) between a generator (4) and a resonator (1) providing a standing wave characteristic, with detection of the variation in the r...
