Abstract: Abstract of the Disclosure A UHF tuning system for providing linear high gain operation over the entire UHF band comprises a field effect transistor (FET) amplifier coupling a received RF signal to a mixer for developing an IF signal, the IF signal being coupled to an IF processing stage by a signal regulating diode.  An AGC control signal is derived from the IF stage for controlling the gain of the FET amplifier which, in turn, is utilized to control the conduction of the regulating diode so as to provide a substantially constant level IF signal to the IF processing stage.   The novel arrangement of the present invention permits the field effect transistor to operate at a lower voltage for more efficient thermal operation and increased reliability while providing a high, flat gain characteristic over the entire UHF band.

Abstract: A B S T R A C T     A method of adjusting the feed movement of a drill rod for drilling a rock by rotating the drill rod by means of a pressure medium operated rotary motor and by feeding the drill rod in a drilling direction and in the opposite direction by means of a pressure medium operated feed motor.  A pressure change acting on the pressure side of the rotary motor due to a change in the rotation resistance of the rotary motor is caused to act on the outlet side in order to reverse the feed force of the feed motor in dependence of the pressure change.  The pressures on the pressure side and the outlet side of the feed motor are controlled so that, when the pressure on one side increases because of the pressure change, the pressure on the other side decreases and vice versa.  In a device for carrying out the method, the pressure medium circuit is provided with means which control the pressures on the pressure side and the outlet side of the feed motor so that, when the pressure on one side increases, the pressure on the other side decreases and vice versa.

Abstract: ABSTRACT         PROGRESSIVE SCAN VIDEO PROCESSOR  PROVIDING VIDEO INTERPOLATION         A processor, for providing a double line-rate video output signal comprising alternating received lines and interpolated lines, comprises three memories.  As each line of incoming video signal is stored in one of the three memories, at a given clock rate the remaining two memories are read at double the write clock rate.  A single averaging circuit, having inputs selectively coupled to the memories, interleaves non-interpolated time compressed lines of video obtained from one of the two memories being read with time-compressed lines of video obtained by interpolation from both of the two memories being read to provide a processed video output signal.          The "write-one read-two" memory organization enables concurrent interpolation and speed-up of the video signal thereby minimizing potential clock timing problems inherent in progressive scan systems of the type where interpolation is provided separately either before or after video speed-up.

Abstract: Abstract In an apparatus for maintaining the orientation of an antenna system with respect to a beacon, radio signals are received in four quadrants and converted into sum and difference signals, which are transformed in frequency, amplified in an amplifier (6) and detected in a first-and second-phase detector (9, 15) present in a corresponding channel (7, 8) to derive error voltages in first and second time intervals respectively for aligning the antenna system with respect to the beacon. During the tracking mode of the apparatus, the difference and sum signals separately pass in first, second and third, fourth time intervals respectively. A VCO (21) supplies two orthogonal signals as reference voltage to the phase detectors. In the tracking mode the VCO is driven by a signal derived from the signals obtained in the first channel (7) in the fourth time interval and in the second channel (8) in the third time interval. With a gain control circuit (27) the gain of the amplifier (6) is adjusted, in response to signals obtained in the first and the second channels (7, 8) in the said third and fourth time intervals respectively, in such a way that the output voltage of the first phase detector (9) in the third and first time interval and that of the second phase detector (15) in the fourth and second time interval are kept constant.

Abstract: ABSTRACT     PORTABLE INSTANT DISPLAY AND ANALYSIS REFLECTANCE SPECTROMETER        A portable analysis spectrometer (10) for field mineral  identification is coupled to a microprocessor (11) and memory (12) through a bus (13) and A/D con-verter (14) to display (16) a spectrum of reflected radiation in a band selected by an adjustable band spectrometer (20) and filter (23).  A detector array (21) provides output signals at spaced frequencies within the selected spectrometer band which are simul-taneously converted to digital form for display.   The spectrum displayed is compared with a collection of spectra for known minerals.  That collection is stored in memory and selectively displayed with the measured spectrum, or stored in a separate portfolio.  In ei-ther case, visual comparison is made.  Alternatively, the microprocessor may use an algorithm to make the comparisons in search for the best match of the mea-sured spectrum with one of the stored spectra to iden-tify the mineral in the target area.

Abstract: ABSTRACT            A seismic source consists of an electroacoustic transducer having a metallic structure, shaped like an empty round paraboloid closed at the base by means of an elastic diaphragm and filled with a proper liquid. Around the focus of the paraboloid two main electrodes are set and an auxiliary electrode is put between the first ones.          The main electrodes are connected to a set of capacitors supplied by a high-voltage power supply. One of the main electrodes and the auxiliary electrode are connected to a trigger pulse generator driven by a remote control via a synchronization pulse generator. The discharge between the main electrodes, primed by a preliminary spark, generates an acoustic pulse through the liquid medium of the transducer on the ground where the paraboloid is engaged. So the transducer generates seismic waves utilized for shallow prospecting both on land and underwater.

Abstract: METHOD FOR DRILLING DEVIATED WELLBORES     ABSTRACT OF THE DISCLOSURE:     Directional drilling of a high-angle wellbore is carried out by the drilling of a vertical first portion to a kick-off point at which a high-angle, deviated second portion is initiated.  The wellbore is cased to at least below the kick-off point.  A casing liner is lowered through the wellbore so that it extends coextensively with the casing.  The liner is spaced from the casing by a casing hanger positioned above the kick-off point.  The liner is sealed in the casing and prevented from rotating during drilling by a packer bore receptacle positioned between the lower end of the liner and the casing.  During the drilling of the deviated second portion of the wellbore, the casing liner protects the casing from wear due to the rotation of the drill string as it lies on the lower side of the high-angle wellbore.

Abstract: MULTIPLE SAMPLE RADIOACTIVITY DETECTOR                ABSTRACT          A detecting head assembly is described which is capable of simultaneously detecting radio-active emissions (such as beta particles) from   multlplicity of samples.  The assembly lncludes a sample holder (1) defining a mult-iplicity of sample receiving zones (2) and structure defining a multiplicity of drift chambers (12).  A beta particle emitted from a sample ionizes gas within the drift chamber (12) and negative ions are funnelled by the application of an electric field, through holes (7) in a mask (6) part of the structure for collection by anode wires (4).  The anode wires are isolated from one another by walls (11), the latter walls and structure being grounded and the sample holder being connected to a high negative potential.  Cathode strips (3) cross-over the anode wires (4) to form crossing points (5) which detect negative ions passing through the respective holes (7). The effect of the electric field is to increase the gain of the detecting head assembly.  The assembly is useful in the field of medical diagnostics and biomedical re-search for providing information relating to radio-active samples.
