Abstract: APPARATUS TO EXPAND A LAMINATING INTERLAYER               ABSTRACT OF THE DISCLOSURE          An apparatus for expanding a laminating interlayer is taught.  The apparatus includes structure for stretching a heated web of laminating interlayer material between a cylindrical heating structure and a conical member in such a manner that a constant rectangular plane is defined in the space between the point at which the web leaves the cylindrical structure and the point at which it contacts the conical member.  The stretching of the web occurs between these two points because the web engaging the larger end of the conical member is stretched to a greater degree than the portion of the web engaging the smaller end of the conical member as the different ends of the conical member are moving at different surface speeds.  The web is cooled on the conical member.

Abstract: SELF-RESETTING JOSEPHSON DEVICE CIRCUIT        Abstract of the Disclosure A self-resetting Josephson device circuit is disclosed which responds to one transition of a circuit input by producing a short output pulse, and which resets itself in response to an-other, complementary transition of said circuit input.  The Josephson device circuit includes a first and second Josephson device, one coupling a dc source to a current sink, said second connected in series with an inductor between said current source and sink.  The circuit input, which is of a square waveform, is applied, in series, to first control circuits of the first and second Josephson devices.  The second Josephson device has a second control circuit to which dc is applied of polarity opposite to the current in the first control circuit and of an amplitude substantially the same as the amplitude in the first control circuit when said circuit input is present.  An output circuit includes a third Josephson device coupled in series with a second inductor and a resistor, with the series circuit coupled to said dc source.  With the output circuit including the third Josephson device connected across the first Josephson device, an output pulse is produced across the second inductance and re-sistance on a high going transition of the circuit input.  On the other hand, if the output circuit is connected across the second Josephson device then an output taken across the second inductor and resistance is produced in response to a low going transition of the circuit input.  In either case, the circuit responds to the complementary transition by resetting itself.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention concerns an electronic correlator for the evaluation of stereo-couples of photographs.  Said electronic correlator comprises a normal correlator into which non-delayed signals are fed which in turn are derived from homologous points of each of the photographs of said stereo-couples.  It further comprises an auto-correlator into which the image signals are fed non-delayed from the one photograph and delayed from the other photograph.  A subtraction unit is connected to the normal correlator and to the auto-correlator.  Furthermore two orthogonal correlators are provided into which the delayed and non-delayed image signals derived from the two photographs are fed crosswise and delayed and non-delayed.  The two orthogonal correlators are followed by a subtraction unit.  By virtue of such an arrangement the trend inherent in the image signal functions to be correlated are taken into consideration and thus the quality of the image correlation is increased.
