Patent EP-0116957-B1 (EP)
IPC: H04R7/18
Filed: 1984-02-16
Granted: 1988-08-24
Abstract: A ribbon speaker system comprising a three-element tweeter, midrange and woofer acoustical transducer unit is disclosed. The tweeter transducer consists of a single, elongated, corrugated aluminum ribbon positioned vertically and connected to the top and bottom of a rigid, elongated frame. Electrical connections are provided at the top and bottom to permit current flow along the length of the ribbon. The aluminum ribbon is located between sets of magnets which are designed to provide a shaped magnetic field that provides magnetic centering of the ribbon. Additional electromagnetic containment for the transducer ribbon is provided by electrical current passing through the ribbon which current returns to its source by means of flat ribbon conductors located on the surfaces of the magnet sets. 
<??>The midrange transducer consists of a single elongated corrugated aluminum ribbon positioned vertically and connected to an elongated frame similar to the tweeter transducer. However, unlike the tweeter transducer, the edges of the midrange ribbon are acoustically sealed to the frame by foam strips. In addition, desired dynamic properties of the ribbon are achieved by fabricating the aluminum ribbon with corrugations that extend at variable slant angles relative to the longitudinal axis of the ribbon. 
<??>The woofer acoustical transducer consists of an elongated, trapezoidal-shaped, corrugated aluminum ribbon that is supported on all sides and mounted vertically in a rigid, elongated frame. To provide a single electrical path through the ribbon it is divided by a series of horizontal cuts into a serpentine pattern. The ribbon is located directly in front of a rectangular array of ceramic magnets mounted on a steel backing sheet.

Abstract: A regulated deflection circuit comprises a deflection generator (60) including a trace switch (35) responsive to a deflection rate signal for generating scanning current in a deflection winding (LH) during a deflection cycle. The deflection generator also includes a retrace capacitance (CR) which forms a resonant retrace circuit (50) with the deflection winding. Switching means (S1,S2) couples a first winding of a flyback transformer (T1) to a voltage source (24) during a first interval of each deflection cycle. A second winding of the flyback transformer develops a retrace pulse voltage across the resonant retrace circuit (50) during a second interval of each deflection cycle. The instants of conduction of the switching means (S1,S2) are controlled for regulating the transfer of energy between the voltage source and the resonant retrace circuit (50) during normal operation. The switching means is arranged for free-running oscillation during a start-up interval to transfer start-up energy between the voltage source (24) and the resonant retrace circuit (50). This causes the resonant retrace circuit to generate a ringing pulse voltage to which said trace switch (35) is subjected, and by which it could be damaged. Means (w3,D16) is provided for disabling normal drive to said trace switch (35) in the presence of said ringing pulse to avoid such damage.

Abstract: To provide for the rapid vaporization of a liquid, a porous body is impregnated with the liquid. Then the liquid contained in the porous body is heated, so as to cause a rapid vaporization of the liquid in the porous body which liquid continually migrates through the porous body under the effect of its pumping and suction capabilities. The whole of the mass of liquid to be vaporized is stored in the body in impregnated form, without the presence of a permanent liquid layer. The liquid is heated directly by passing an electric current through the porous body, the density of the porous body being chosen so as to provide a liquid retention capacity allowing a variation of the energy dissipated in time to be obtained in accordance with a predetermined law which is a function of the density chosen for the porous body. Thus interchangeable porous bodies can be used having different densities and allowing different curves of variation of the energy dissipated in time to be obtained, respectively. To provide for operation in any position the liquid is introduced and stored in a liquid mass to be vaporized solely in impregnated form directly inside the porous body, without formation of a permanent liquid layer in a housing for the porous body.
