Abstract: A METHOD AND DEVICE FOR DETECTING A SPECIFIC SPECTRAL FEATURE                       Abstract of the Disclosure A method and device for detecting a narrow spectral feature in a sample is described.  The method includes the steps of providing a beam of light having an optical frequency bandwidth which is narrow compared to the width of the narrow spectral feature and having a center frequency .omega.C which lies near the narrow spec-tral feature, phase modulating the beam of light with a single RF frequency to provide a pure FM spectrum having upper and lower sidebands, exposing the sample containing the narrow spectral feature to the modulated light so that only one of the FM sidebands probes the narrow spectral feature, photodetecting the light emerging from the sample to detect a RF beat at the specific RF frequency used for phase modulation, and electronically monitoring the amplitude of the RF beat signal to indicate the strength of the narrow spectral feature.  A preferred embodiment of this invention is a multiplex readout device for hole burning memories.  The device includes means for using a frequency modulated laser light with widely spaced sidebands arranged so that only one of each pair of upper and lower sidebands probes the frequency location of each hole.  The device uses many simultaneous RF frequencies to drive the phase modulator and produce the light with FM sidebands which simultaneously probes all the hole locations of interest.  The device includes photodetection means to receive the light after it has passed through the sample and phase sensitive multiplex analyzing means to process the electrical signals from the photodetection means to indicate the presence or absence of holes.

Abstract: ABSTRACT:           Control circuit for controlling a laser drive current.  In known control circuits certain levels of the optical output signal are kept constant.  This renders it difficult to satisfy certain requirements during the life of the laser as regards the linearity of the modulation of the optical output signal.  In the described control circuit the intermodulation of two signals present in the modulation signal with substan-tially constant amplitudes is measured, an error signal which controls a component of the drive current being derived therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE           In a method for the production of heat using a heat pump in which a heat carrier fluid is heated by a heat exchanger and compressed with temperature increase in a subsequent condensor, heat is delivered therefrom to a heat-admitting process; the fluid is then relaxed (i.e. expanded, as used synomymously here-in) in a gas turbine, producing work, and afterwards its residual heat is delivered to a thermal power process, the maximum temper-ature of the energy sources of which, that provide work for the condensor, lies below the temperature of heat delivery.  The main heat source can consist of an exothermic chemical or nuclear reaction and the heat-admitting process can be a coal gasification process.  The work in the condensor is furnished essentially by the gas turbine and the thermal power process.

A cutting blade carried by a movable tape applicator is driven past a stationary window member through which the splicing tape is fed, for cutting the splicing tape by action of the cutting blade against a cutting edge formed in the window.  The cutting blade is rotatably mounted to the tape applicator and biased outwardly therefrom for holding the blade against the window member for properly cutting the splicing tape.          As the tape applicator travels subjacent to the window member, the cutting blade is rotated through an arcuate path beneath the window member; the cutting edge of the movable blade is rotated to a position for preventing cutting of the magnetic tape and a pressure surface of the blade is simultaneously carried into a position for pressing against the splicing tape during application of the same to the magnetic tape junction.      An air cylinder is utilized to drive the tape applicator through the cutting operation and onto the magnetic tape for applying a pressure force against the magnetic tape to properly seal the splicing tape across the tape junction.          A pair of springs working in conjunction with the air force powering the air cylinder provides a controlled pressure during splicing tape application.
