Granted: 1981-12-29
Abstract: ABSTRACT OF THE DISCLOSURE           The specification describes a housing which is mountable on one side of a printed circuit board.  The housing comprises a base defining a first bearing surface and having dependent leg means extending from one side of the printed circuit board through an opening in the board toward the opposite side thereof for engaging an edge of the opening.  A cover defines a second bearing surface which is directly engaged with the first bearing surface for supporting relative movement of the cover with respect to the base.  The cover has integrally dependent legs movable on cover movement relative to the base, such cover leg means thereby being movable through the opening in the printed circuit board into engaging relation with another edge of the printed circuit board opening.  The base legs and the cover legs thereby cooperatively mount the housing.

Abstract: Abstract of the Disclosure Gamma spectrum measurement signals received from a downhole instrument containing a scintillation counter are coupled into a multi-channel analyzer.  The analyzer converts the received pulses to pulses in separate channels according to energy levels of the received measurements.  The energy channels from the multi-channel analyzer are coupled to digital decoders which are set up for energy level windows for pre-selected elements and the total occurrence count.  The outputs are coupled into a microprocessor stripper which includes storage buffers sized in accordance with the logging rate and crystal utilized in the scintillation counter.  These storage registers permit filtering in addition to stripping the various energy channels of the influence radiation caused by the elements having an energy band centered around a higher energy level.          After the stripping occurs, the outputs for each of the selected energy channels may be coupled into a digital recorder or into count rate meters for conversion to analog voltages for driving a chart recorder.

Abstract: ABSTRACT A circuit arrangement for controlling a multi-beam acousto-optical cell in which Bragg diffraction is used for the generation of a plurality of out-going laser beams, in which the acousto-optical cell has at least one ultra-sonic transducer from which the outgoing laser beams are coming out in a common plane, the circuit arrangement comprises VHF or UHF oscillators coupled through respective control stages to the ultrasonic transducers.  The frequency of each oscillator defines the diffraction angle of an associated outgoing laser beam the intensity of which is dependent from the amplitude of the oscillator.  The passage of the oscillator outputs towards the respective ultrasonic transducers is controlled by the control stages according to pre-determined operational requirements.  In order to enable the generation of out-going laser beams with variable diffraction angles within the common plane of the outgoing beams at least one of the high frequency oscillators is designed as an oscillator of variable frequency having a frequency determining input. By means of applying a control voltage to this frequency determining input the diffraction angle of the corresponding outgoing laser beam can be adjusted during operation which has advantages in certain fields of application.
