Abstract: A reversible thermosensitive coloring composition is composed of (i) an electron-donor coloring compound and (ii) an electron-acceptor compound selected from the group consisting of an organic phosphoric acid compound, an aliphatic carboxylic acid, and a phenolic compound, each having a straight chain or branched chain alkyl group or alkyenyl group having 12 or more carbon atoms, the electron-donor coloring compound and the electron-acceptor compound being capable of reacting to induce color formation in the reversible thermosensitive coloring composition at the eutectic temperature thereof. The electron-donor coloring compound and the electron-acceptor compound, when fused and colored in a mixed state, with application of heat thereto, followed by rapidly cooling the fused mixture, exhibit an exothermic peak in a temperature elevation process in a differential scanning calorific analysis or in a differential thermal analysis. A recording medium and display medium using the above reversible thermosensitive coloring composition, a recording method of using the recording medium, a display method of using the display medium, a display method of using the display medium, and a display apparatus using the display medium are disclosed.

Abstract: A pulse-echo system uses ultra-sound signals to detect discontinuities or flaws in a wall. The system comprises a transducer which transmits ultra-sound signals and receives reflected ultra-sound signals, and reflection means (3,5,6) which comprise at least two reflection planes (3,5,6) which create two paths for the ultra-sound signals. The two paths (12,13) meet in the wall such that they are essentially perpendicular to each other. At the location of a discontinuity (4), where the two paths meet, the ultra-sound signals are reflected back along the respective paths to be detected at the transducer (2). The path lengths can be varied by altering the relative positions of the reflection planes. One of the paths (13) for the ultra-sound signals may have a circumferential component within the wall. In this way a wide range of orientations of discontinuities can be detected.

Abstract: The present invention relates to a method and apparatus for treating electrically conductive fluid. Positive (1) and negative (2) electrodes of electrically conductive materials having different electrochemical potentials are spaced apart and electrically isolated from one another so that the only electroconductive connection that develops an electrochemical potential between the electrodes (1,2) is established by fluid to be treated flowing between the electrodes. Such fluid is therefore ionized which will both prevent the precipitation of solids from the fluid which would tend to form a scale on the inner surface of piping through which the fluid flows, and aid in the removal of a previously formed scale. A third electrode (3) is also provided so as to be electroconductively connected with the positive electrode (1) but electrically isolated from the negative electrode (2). Therefore, the third electrode (3) will release metal ions into the fluid. These ions will inhibit the release of compounds into the fluid having a principal element that is the same as that of the metal ions released by the electrode (3). In such a way, the fluid can also be treated to inhibit a particular compound, to which the fluid might be exposed, from dissolving into the fluid.

Abstract: Device for motorising the locking mechanism of doors with linear, perimetric bolts, consisting of a frame comprising an endless screw driven by two DC electrical motors. The displacement of the bolt driven by the endless screw causes the rotation of a drive arm which causes, in turn, the rotation of a driven arm. In the anti-break-in version, the arms are secured to one another by the core of an electromagnet, the coil of which, when supplied with power, separates the two arms, while, in the anti-panic version, the driven arm, totally separated from the drive arm, is equipped with a return spring which is tensioned by an electromagnet, the supply of which only needs to be switched off in order to unlock the door. <IMAGE>

Abstract: The method and device treat the surface of a substrate by depositing on it, for example, a coating using the projection of a plasma flow produced as follows. An electric arc is created in a chamber (2) between a cathode (5) and an anode (1). An inert gas is introduced into the chamber (2) so that it is ionised when passing through the electric arc and forms a high-temperature plasma. The plasma is ejected out of the chamber through an ejection nozzle (3) whose outlet (4) is in the shape of a slit so as to project particles of a material forming the coating, which are melted by contact with the plasma, onto the substrate and form a coating on it. The electric arc created between the anode (1) and the cathode (5) extends along an axis approximately parallel to the axis of the outlet slit (4) of the ejection nozzle (3). The inert gas is introduced into the chamber (2) along several directions (F1) which are radial with respect to the axis of the electric arc. The material to be projected is conveyed by a carrier gas in pipes (12) which open, for example, into the inside of the ejection nozzle (3).
