Abstract: PHF 83.589                  12                5.5.1984 ABSTRACT: Method of and device for scanning objects by ultrasound echography.            A method for the scanning of non-linearly dispersive objects whereby changes of the energy spectrum of echographic signals can be quantitatively related to parameters of the objects examined, that is to say the ultrasonic attenuation factor .beta. and the exponent r which characterizes the relationship between the non-linear variation of the attenuation and the frequency. To this end, the signals received are split into a number of (n) substantially  equally wide, consecutive frequency bands which together cover approximately all frequencies of the signals received. The envelope of the signals in each frequency band is determined and each of the envelopes is multiplied by a correction signal in order to compensate for the diffraction  effect. The logarithm of the envelopes  thus corrected is determined, after which the following operations are performed by means of the n signals thus obtained:           (a) the slope .beta. f? of each of these n signals is determined;           (b) this signal .beta. f?  is converted into logarithmic form;           (c) in a table or a curve the relationship is laid down,  between the logarithmic value of the frequency for each channel log fi and the logarithmic value log .beta. f? i determined sub (b); (d) the slope of the curve thus obtained and the value of log .beta. fr for log f = 0 are determined.

Abstract: ABSTRACT A jitter canceller for carrier phase control associated with a receiver of a data transmission system for transmitting data over telephone lines is disclosed.  The jitter canceller includes circuitry which detects carrier phases of complex baseband signal which carrier phases are stored.  A phase predictor responsive to the detected carrier phases produces a predicted carrier phase.  This predicted carrier phase is used as a basis for compensat-ing for carrier phase deviation of a complex baseband signal.  An error detector detects any error associated with data discriminated from the complex baseband signal and this error is minimized by controlling the phase predictor.  The invention accomplishes considerable jitter suppression capability without sacrificing the noise suppression capability of a conventional phase locked loop.

Abstract: ABSTRACT OF THE DISCLOSURE      A radioactive aerosol inhalation apparatus includes a lead-shielded container, having a lid or cover, and a disposable aerosol inhalation device for use in producing properly sized radioactive tagged particles.  The disposable device includes a mouthpiece attached to a wye connector containing a valving system for inhalation of the radioactive aerosol and exhalation to an entrapping filter.  Conduits are respectively provided by flexible tubing from a nebulizer and to the filter.  The optimum range of particle sizes is generated by producing an aerosol in the nebulizer which has-an internal baffle.  For ease of handling and to minimize radiation exposures, an entry is provided to add radioactive solution directly into the baffled nebulizer.  A method involves using the apparatus to supply an aerosol containing radioactive tagged particles to a subject or patient for treatment and/or diagnosis.

Abstract: ABSTRACT OF THE DISCLOSURE     A separable terminal assembly of a separable slide fastener includes a separable pin mounted on one stringer tape along one longitudinal edge thereof, the separable pin including a pair of plates interconnected at one longitudinal edge and disposed one on each side of the stringer tape.  Each of the plates has a flange extending along the other longitudinal edge of the plate and a bevelled upper end wall held in abutting engagement with the endmost coupling element disposed next to the separable pin. The bevelled upper end walls slope down in a direction from the one toward the other longitudinal edge of each plate.   The flanges terminate short of the respective bevelled upper end walls so as to define between the plates and the flanges a pair of openings for allowing the one longitudinal tape edge to flex laterally toward the other longitudinal edge of the stringer tape while the endmost coupling element passes through a branch of the Y-shaped guide channel in a slider.  The separable pin thus constructed can easily be inserted into and removed from a mating retainer without special manipulation.

Abstract: APPARATUS FOR ENCODING AND DECODING DIGITAL DATA TO PERMIT ERROR CORRECTION                   ABSTRACT OF THE DISCLOSURE           Apparatus to punt the correction of a single bit error occurring in a sequence of data packets (e.g. bytes) comprising data bits.  An encoder produces an error correction packet (e.g. byte), the value of which is determined algebraically from the value of bits in the data sequence.  All data packets and the error correction packet have a predetermined parity.  A decoder receives the sequence of data packets and error correction packet.  If a single bit error in the data bits has occurred during transmission, one data packet is identified as having in it the bit in error.  Algebraically the data bit in error is identified and corrected.

Abstract: CAST-TO-SIZE EPOXY TOOLS FOR           STAMPING SHEET METAL PANELS          Abstract of the Disclosure Very large tools can be cast-to-size by making a pattern of the article to be formed by the tool, laying the pattern up in a pattern box, applying a release coat and coating the pattern and box with a tough, curable tool surface layer.  A small amount of epoxy filled with a thermally conductive particulate filler is cast into the pattern box before he surface layer fully cures.  Relatively large chunks of thermally conductive material are added to the box which are covered with additional cast epoxy.  The cure of the epoxy is controlled to effect complete cure at room temperature within a few days but never to exceed a peak cure temperature above about 70°C.

Abstract: ABSTRACT   An article of manufacture which has at least a part that is formed from metallic copper has, on a surface of the copper part, an adherent, sub-stantially contaminant-free refractory layer and an intermediate layer formed from a metal which acts as a barrier to diffusion of oxygen or copper or both. The intermediate layer has a thickness of at least 1.1 micrometres.  It has been found that, in articles according to the invention, the metal forming the intermediate layer eliminates or substantially reduces the mechanisms by which failure occurs, thus extending the high temperature lifetime of the article.  Thus, for example in the case of circuit or signal integrity cables, the time required to cause circuit failure in a fire would be substantially increased.  The metal forming the intermediate layer for this purpose may be one which acts as a barrier to diffusion of either the underlying substrate to the outer surface of the article or to the diffusion of oxygen into the sub-strate.  It may restrict diffusion in its elemental form or it may hinder diffusion processes, by formation of oxide scales when exposed to air, as is the case with for example Aluminium.  Such scales are most effective if they are stable on formation and exhibit low growth rates.

Abstract: L'invention concerne un appareil universel de détection de défectuosités dans des systèmes à microprocesseur. Il est bien connu que les microprocesseurs se présentent sous la forme de circuits intégrés comportant une pluralité de broches. L'appareil de détection comporte ainsi un connecteur muni de broches positionnées de façon à pouvoir être insérées dans le dispositif de connexion du microprocesseur d'un système à dépanner, en remplacement des broches de ce microprocesseur après que celui-ci ait été retire. Une interface définit pour chaque broche du connecteur une ligne ayant une direction programmable. Un contrôleur programmé associé à une mémoire qui mémorise une copie du logiciel du système à dépanner est relié à l'interface pour (a) programmer la direction des lignes afin de simuler les liaisons qui sont normalement établies entre le système à dépanner et son microprocesseur, et (b) effectuer sur ce système, à travers les liaisons simulées, des essais permettant de détecter la défectuosité. Le contrôleur peut évidemment être programmé pour détecter des défectuosités dans plusieurs systèmes à microprocesseur différents, la mémoire qui lui est associée mémorisant alors une copie du logiciel de tous ces systèmes.
