Abstract: COAXIAL HYBRID COUPLER AND CROSSING ELEMENT             ABSTRACT OF THE DISCLOSURE        A microwave crossover  (20)  by which an electromagnetic wave can crossover from one waveguide to another waveguide is formed completely within a planar structure having two hybrid couplers (28, 30) arranged in tandem with output ports of the first coupler connected to input ports of the second coupler.   Each coupler is formed of an electrically conductive housing (40) and two electrically conducting bars  (56,  58)  disposed therein and insulated therefrom.  The bars are disposed in a common plane and are equally spaced from top and bottom walls of the housing.  A central portion (52) of each bar is angled relative to end portions of the bars to permit a crossing over of the bars at the central portions thereof.  Each of the central portions is formed with a notch (60) which engages with the notch of the other bar while maintaining a gap therefrom, the notches permitting the crossover to occur in the foregoing plane.   Ends of the bars protrude through openings in the housing in the form of coaxial transmission lines.  The crossing (54) of the bars has the effect of a twist of central conductors 932) of the coaxial lines resulting in a relocation of the ports of the coupler such that the two input ports (36, 38) are on an input side of the coupler, and two output ports (44, 46) are on an output side of the coupler.   This arrangement of the ports permits the connection of two couplers in tandem to provide for the planar configuration of the microwave crossover.

Abstract: ABSTRACT OF THE INVENTION    A method for determining the mean depth of penetration of one or more radioactive tracers injected by a hydraulic fracturing process into a fractured formation disposed about a well bore as an indication of the extent of radial frac-tures including the steps of measuring with a radioactivity detector in the well bore at the depth of the formation frac-ture, the degradation of the gamma ray energy spectra of the radioactive tracer in the fractured formations resulting from the traverse of radiation through the formations and borehole to the detector; obtaining a ratio   the count rates CA and CB in two energy ranges where the range for obtaining CA is sensitive to primary radiation reaching the detector without Compton scattering and the other region for obtaining CB  detects radiation degraded through Compton scattering collisions.  The ratio   is a tracer penetration index (TPI) corresponding to the mean radial distance R between tracer and detector and the extent of radial fracture.  For removing potential interference in the determination of R due to the presence of the tracer in the borehole, the method also pro-vides for obtaining a ratio of count rates M/P in two low energy regions of the tracer spectrum - one region "M" sen-sitive only to Compton scattered radiation and a region "P" sensitive to photoelectric absorption in iron.  The ratio M/P is a tracer borehole index (TBI) which indicates the relative presence of tracer in the formation compared to the borehole, and whether the borehole count rate obtained from a selected interval of well bore containing only borehole tracer needs to be removed from the total spectra observed in an interval of interest to obtain a borehole insensitive calculation of tracer penetration index.

Abstract: ABSTRACT        IMPROVEMENTS IN OR RELATING TO METHODS OF     MANUFACTURING TUBE COUPLING BODIES        The disclosure relates to a method of manufacturing a tube coupling body in a plastics material using injection moulding tooling.  The  body is formed with a cylindrical bore having enlarged end portions in a mould body and using removable cores. The cores form both the internal bore of the mould body and also end parts of the mould body so that once the cores are removed, end parts of the coupling body are revealed in the mould.  Whilst the end parts are still hot from the initial moulding operating, forming dies having tapering end cavities are pressed over the end parts of the moulding to form the end parts of the moulding with both external and corresponding internal tapered surfaces.  The tapered internal surfaces of the end parts thus formed provide tapered cam surfaces for engaging the resilient arms of collets to be inserted in the coupling body to receive and lock tubes in the coupling body.

The routing network switches messages in a plurality of switching stages, with each stage connecting to the next stage through communications paths that are divided into groups, each group, in turn being associated with selected address signals.  A communications path continuity test circuit associated with each path detects any discontinuity in the communications path and disables the path.  Thus, the stage may attempt to transfer a message over another path associated with the same address.

Abstract: A method and a circuit arrangement for modifying central control information commands forming signal programs in traffic signal systems in particular street traffic signal systems, the central control information commands being output from a central station to intersection devices of the system in order to control signal generators assigned to the intersection devices. This modification is to occur through the use of traffic information which are determined in the traffic areas whose traffic flows are to be controlled by the signal generators of the intersection devices. In order to be able to undertake a modification of the signal program sequencing in the respective intersection devices, modification time areas are determined in the form of partially overlapping central control information commands, in particular binary "1's" transmitted from the central station to the respective intersection device. Within these modification time areas, separate local control information commands can become effective for setting the signal generators.
