Abstract: In the renovation of old chimneys, a new circumferentially insulated inner tubing (1) is inserted from above into the shaft of the existing outer casing (4). For this, the individual tube sections (1a) of the inner tubing (1) have to be equipped, before introduction into the outer casing (4), with an external thermal insulation composed of tubular insulating shells (2, 3, 3a). So that the tubular insulating shells (2, 3, 3a) can be attached simply and in a trouble-free way by being pushed on, but at the same time guarantee a firm fit on the tube section (1a) by friction, the tube sections (1a) are manufactured with a considerable oversize (x) in relation to the outer surface of the associated tube sections (1a), thereby guaranteeing that they can be pushed on in a trouble-free manner. The necessary frictional fit is obtained by means of a continuous bead-like end tapering (7) which engages at the end of the pushing-on movement and secures the frictional fit with an adjustable surface pressure. This design of the tubular insulating shells (2, 3, 3a) requires no additional production outlay if the shape of the winding mandrel is given an appropriate contour. <IMAGE>

Abstract: A batteryless, portable, transponder useful in a tag for a presence detection system. The transponder detects electromagnetic radiation at a first predetermined frequency and responds to said detection by transmitting electromagnetic radiation at a second frequency that is a subharmonic of the first frequency. The transponder includes an amorphous magnetic material component (48) for storing energy from the electromagnetic radiation detected at the first frequency for transmission as the electromagnetic radiation transmitted at the second frequency. In one embodiment (Figure 9A), the transponder includes a thin, flat ribbon (48) of low coercivity magnetostrictive amorphous magnetic material having a transverse uniaxial magnetic anisotropy defining a magneto- mechanical resonant frequency "f" in accordance with the dimensions of the ribbon, when in the presence of a magnetic bias field of a predetermined intensity, wherein the ribbon responds to the detection of electromagnetic radiation having a frequency "2f" by transmitting electromagnetic radiation at a subharmonic of the frequency "2f"; and means for biasing the ribbon with the predetermined magnetic bias field. In another embodiment (Figure 1), the transponder consists of a single resonant circuit including a nonlinear inductor (L1) having a core made of amorphous magnetic material; and a capacitance (C1) connected in series with the inductor to define the resonant circuit. The core of the nonlinear inductor includes an elongated thin, flat ribbon of low coercivity amorphous magnetic material. It has been observed that this resonant circuit exhibits a bifurcated frequency-division characteristic in relation to the amplitude of the detected electromagnetic radiation at the first predetermined frequency, whereby additional frequency divisions occur as the amplitude is increased. A coded tag (Figure 10) includes two amorphous magnetic material transponders (60, 62) that detect electromagnetic radiation at different frequencies.
