Abstract: Abstract In the determination of equivalent echo channel pulse response, digital filtering techniques of the transversal adaptive type are used, and the pulse response of the equivalent echo channel is subdivided into three intervals, the second of which consists of the significant portion of the pulse response and is determined by an iterative search for the value and position of the coefficient of maximum absolute value; the first represents a pure delay and the third represents the contribution of the lowest frequencies of the base band.  In simulating the echo-signal only the pulse-response coefficients whose index is comprised in the second interval are considered, together with samples of the signal to be copied belonging to preceding sampling instants whose index is also comprised in the second interval.

Abstract: ABSTRACT            The invention relates to a method of drying a solid wetted with a solvent or solvent mixture by causing superheated vapour of said solvent or solvent mixture as a carrier medium to flow through the material to be dried in an eva-poration room, said solvent or solvent mixture evaporating and being carried along with the carrier medium, and by then causing the evaporated solvent or solvent mixture to condense from the carrier medium, if desired after com-pression thereof, in a cooling device. During this drying process a sub-ambient pressure is provided in the evapora-tion room and the temperature in the evaporation room is controlled by adjusting the sub-ambient pressure, if de-sired, in combination with an additional temperature con-trolling means. The invention also relates to a device for using the above method.

Abstract: ABSTRACT OF THE DISCOSURE   More than ten different wavelength channels are multiplexed over a single optical fiber for use in optical slip ring assemblies.  The ends of multimode fibers, through which light signals of different wavelengths are transmitted, are packaged and fused to the end of a large core fiber.  The single large core fiber in which the com-bined signals are transmitted can be used in a optical slip ring asssembly in the same way as a single fiber containing one wavelength.  The alignment accuracy is greatly enhanced for the large core fiber.

Abstract: ABSTRACT OF THE DISCLOSURE    A method  for  phase-locked  sampling measurement  of a periodically varying quantity.   The samples are desig-nated g(I) ... g(I-n) and may comprise one complete period or a half of one period.   The method involves adapting the sampling frequency and the sample position in relation to the quantity to be measured such that phase locking is  attained,  and  this  is done by controlling the time interval between sampling.  Whether the sampling frequency needs  to be increased,  left unchanged or be decreased, depends on a number of decisions depending on the values of samples g(I) and g(I) - g(I-n).  A device for carrying out the method is also described.

Abstract: Abstract of the Disclosure An improved harvester for harvesting a salt crop from the bottom of a shallow, elongated solar crystallizer containing a substantially saturated salt solution overlying the salt crop.      The harvester includes track means extending longitudinally along the sides of the crystallizer on which a pair of carriages are movably  mounted  and  support  the  ends  of  a  frame  extending transversely across the crystallizer. The frame includes salt gathering means for transferring the salt crop laterally in the form of one or a plurality of longitudinally extending furrows or ridges in response to the travel of the harvester along the tracks and the resultant gathered salt is extracted by one or a plurality of suction inlets disposed in alignment with the furrows in the form of an aqueous brine slurry.  The extracted salt crop is subsequently separated and recovered while the liquid brine is returned  to  the  crystallizer.   The  harvester  enables  the harvesting of a solar salt crop while retaining a protective layer of  substantially  saturated  brine  over  the  salt  crop  while simultaneously  maintaining  a  salt  floor  or  bottom  in  the crystallizer of a preselected thickness.

Abstract: ABSTRACT: Self-oscillating power-supply circuit.     For energizing a load (10) with different input voltages, the circuit comprises a transformer (6), whose primary winding (n1), in series with the collector-emitter path of a switching transistor (T1), the load (10), and a current, sensing resistor (R2), is arranged between the input-voltage terminals. The secondary winding (n2), in series with a diode (D1), is arranged in parallel with the load (10). When the input voltage is applied a very small base current is fed to the switching transistor (T1) via the starting resistor (R1), which results in a small current in the primary winding.   The resulting voltage rise across the secon-dary winding (n2) ensures that the switching tranistor (T1) is bottomed rapidly via a positive-feedback loop, which comprises the series arrangement of a first resistor (R4), a capacitor (C1) and a second resistor (R5) and which is arranged between that end of the secondary winding (n2) which is connected to the diode (D1) and the base of the switching transistor (T1). For a specific current in the primary winding (n2)the switching transistor (T1) is turned off by means of a control transistor (T2), whose base is connected to the current-sensing resistor (R2). The energy stored in the transformer (6) is then delivered to the load (10) by an output current in the secondary winding (n2).          In order to prevent this output current from increasing strongly at increasing input voltages as a result of the increasing saturation of the switching transistor (T1) via  the positive feedback, a zener diode (Z1) is arranged between  the junction point of the capacitor (C1) and the resistor (R5) and the base of the switching transistor (T1). Above a specific input voltage this zener diode (Z1) is turned on and drains the base supply current to the emitter of the switching transistor.

Abstract: ABSTRACT       A dual string well packer which is anchored at a downhole location within the bore of a well casing string by relative longitudinal movement between the primary tubing string and the secondary tubing string.  The well packer is set by applying tension via the secondary string.  The well packer is released from its downhole location by applying tension via the primary string.  The invention is particularly adapted for use in well completions that are subject to thermocycling such as steam injection wells.  However, the anchoring and releasing mechanism of the present invention can be readily adapted for use with any dual string well packer.  The present invention includes an improved method for well completion, minimizing tubing handling requirements during the installation and removal of the production tubing strings and associated dual string well packer.
