Abstract: ABSTRACT OF DISCLOSURE             A method for detecting, monitoring or measuring visible and ultraviolet radiation exposure wherein a liquid crystal element covered with a coating layer trans-parent to the radiation is placed in the path of the radiation to be monitored and then the shift of the spectral reflectance or transmittance of the element is measured, this shift being a measure of the radiation dosage.  This shift may be measured using reference liquid crystal elements or a spectrophotometer or similar measuring devices.

Abstract: ABSTRACT OF THE INVENTION           A digital correlator compares two digital words a plurality of times.  Each time the second digital word is shifted by one additional bit with respect to the first digi-tal word.  The results of the various comparisons are stored.          The stored results are then searched to find the location of the results indicating the greatest similarity between the bits of the first and second digital words.  This location is indicative of the number of bits by which the second digital word is displaced with respect to the first digital word when greatest similarity occurs.

Abstract: ABSTRACT OF THE DISCLOSURE          A flexure-suspended, free-rotor gyroscope is disclosed.  It includes a drive shaft journalled in a housing and a rotor driven by the drive shaft to spin about a spin axis.  The rotor is flexibly supported so that it can tilt about two tilt axes perpendicular to the spin axis.          A magnetic circuit disposed at the periphery of the rotor defines an annular air gap.  A permanent magnet disposed within the magnetic circuit provides a unidirectional radial magnetic field regularly undulating in magnitude around the air gap.  An assembly of discrete coils is supported from the housing for detecting the undulating radial magnetic field when the rotor spins.                                      .

Abstract: APPARATUS AND METHOD FOR DETECTING ERRORS IN A     by Adam Lender ABSTRACT OF THE DISCLOSURE           The correlation properties of a 7-level correlative waveform permit detection of errors due to irregularities and impairments in the transmission facility, where these errors violate the correlation patterns of the waveform.  The re-ceived 7-level correlative waveform is first decoded to obtain a pair of binary outputs which are representative of the original binary signal at the transmitter, except for errors that might have occurred during the transmission period.  The pair of binary signals are operated on to obtain coded binary signals and their delayed counterparts.  These coded binary signals are used to establish the effect of presence or ab-sence of a top or bottom level that would result from the formation of a nonbinary correlative signal.  If an error has occurred during transmission, the extreme levels of the locally generated signal will not normally coincide with those of the received signal.  To determine if an error has occurred it is necessary to compare the extreme levels of the incoming wave-form with those locally generated.  Thus, the decoder provides the bottom and top level outputs which are compared with the extreme levels of the equivalent signal from the binary coded signals, and when occurrences of extreme levels of the two signals differ, it is an indication that an error has occurred.  The error indication results in an output signal from the error detector circuitry.

Abstract: ABSTRACT A method of producing extrusion profiles of a desired length comprises the steps of processing a billet of pre-selected billet length in a press measuring the extruded length during the extrusion process, switching off the extrusion process upon reaching the desired extruded length and varying the billet length such as to obtain the optimum butt thickness or switching off the extrusion process upon reaching the minimum permissible butt thickness and enlarging the billet length such as to obtain the desired extrusion length.  An apparatus for carrying out said method comprises a billet hot shearing unit which has an adjustable longitudi-nal feed stop and cuts the billets to length.  The billets are supplied to and processed in a press, in which a first length recorder measures the butt thickness and from which the extruded profile is drawn out by an extrusion drawing unit.  A second length recorder measures the extrusion length.  The measured actual values of the butt thickness and the extrusion length are supplied to a controller which compares them alternately with corresponding reference input values of the butt thickness or the extrusion length respec-tively and actuates a positioning element which adjusts said longitudinal feed stop such as to eliminate a difference between said reference and actual values.
