Abstract: In accordance with an illustrative embodiment of the present invention, a method and apparatus is disclosed for determining the content of a selected number of materials in an earth formation penetrated by a borehole from the spectrum of gamma radiation emitted by the materials in the formation. By deriving representations of portions of the detected gamma radiation spectrum and combining the representations, the content of the selected materials is determined. A special filter arrangement provides for an improvement in such a determination by effecting a reduction of an anti-correlation relationship between the determined contents of materials having closely related spectra. This reduction is achieved without sacrificing the resolution of the measurements along the borehole.

Abstract: A switching power converter comprises a DC power source (1), a switching element (2) and a transformer (3) interconnected so that the DC power source supplies power to the primary winding (3a) of the transformer (3) through the switching element. A rectifier (4, 5) and an output filter circuit (6, 7) are connected to the secondary winding (3b) of the transformer (3). A parallel circuit comprising a capacitor (12) and a coil (13) is inserted in the current path of the primary winding. A control circuit (14) controls the ON and/or OFF states of the switching element so that the switching element is turned to the ON state when the current in the coil (13) reaches a predetermined value which depends upon the output power of the power converter, and the switching element is turned to the OFF state after the current in the switching element reaches zero. Since the current in the switching element is zero when the switching element is turned to the OFF state, no power loss occurs in the OFF transition, and the conversion efficiency is thereby improved.

Abstract: An FM signal demodulation system comprises a signal level detector (1), an adaptive bandpass filter (2), a frequency discriminator (3), amplifiers and amplitude limiters (4,5), and a fixed-bandwidth reference bandpass filter (8). The FM signal is fed to an input terminal (6) and the demodulated output is obtained from an output terminal (7). 
     The threshold level for demodulating the FM signal, for example a television picture signal, is improved by restricting the bandwidth of the signal using the adaptive bandpass filter (2), thereby improving the picture quality and/or the signal/noise ratio of the demodulated signal. The adaptive bandpass filter has a wide bandwidth when the signal level is sufficiently higher than the threshold level, but a narrow bandwidth when the signal level is close to or lower than the threshold level. The bandwidth of the adaptive bandpass filter is adjusted according to the total power of the input FM signal, or the carrier signal to noise ratio.

Abstract: Apparatus for sensing the magnitude of an electric current flowing in a conductor (10) comprises an optical fibre (12) wound around the conductor, a laser (18) arranged to inject plane- polarised light into the fibre, and a Wollaston prism (30) and photosensors (32) arranged to sense the angle through which the plane of polarisation is rotated by the Faraday effect of the current's magnetic field on the light traversing the fibre. In order to avoid attenuation of the Faraday rotation owing to birefringence, the fibre is twisted strongly about its own axis; furthermore, one end of the fibre is metallised (22) so that the light traverses the fibre in both directions before entering the Wollaston prism, thereby cancelling any temperature- sensitive rotation of the plane of polarisation arising from the twisting of the fibre. <IMAGE>
