Abstract: In a homodyne receiver with a phase-locked loop, it is to be ensured that when the phase-locked loop is locked in, the arithmetic mean of the signal magnitude of the heterodyne signal always essentially corresponds to a signal magnitude of a data output signal in the arithmetic mean. For this purpose, a feedback loop (4) for generating a quantised feedback of the heterodyne signal (ÜS) generated by the receiver is provided in addition to the phase-locked loop (3), the heterodyne signal (qÜS) fed back quantised in the feedback loop (4) being heterodyned with the heterodyne signal (pÜS) fed back in the phase-locked loop (3). <IMAGE>

Abstract: A metal detector is proposed in the case of which it is possible to use a sensor provided with two coil pairs to trace hidden metal in a wall and determine the depth of said metal. The two coil pairs are each connected to an oscillator and oscillate continuously at different frequencies. The signals influenced by the metal are measured and weighted for evaluation. An intensity display characterises the position of the metal. For the purpose of depth measurement for the hidden metal, after the metal has been traced a lifting mechanism is actuated and lifts the metal detector by a defined amount. The depth of the hidden metal is calculated by means of a repeated measurement, taking account of the prescribed altered distance from the wall surface. A manually operable marking device marks the site of the measurement. <IMAGE>

Abstract: A data processing method and system are disclosed to provide active pigeon hole sorting for mail pieces in a postal system. The method is based upon the receipt of deferred optical character recognition statistics for mail pieces in transit to a destination postal region. An ordered list of addressees is compiled from the DOCR statistics. From this ordered list, the sorting case for sorting the mail is partitioned to eliminate pigeon holes for those postal recipients not receiving mail on that day. Still further, the pigeon holes in the sorting case are actively indicated with a prompting light to facilitate the operator physically sorting the mail piece down to delivery sequence. The assignment of delivery stops to pigeon holes is also developed so as to designate adjacent pigeon holes based on the carrier walk without regard to street number but rather to reflect geographic juxtaposition.

Abstract: A drill pipe (10) is disclosed which includes a cylindrical pipe section (12), a box end (14), a pin end (16) and a hydraulic hose assembly (18) connected between the box and pin ends and extending within the cylindrical pipe section. By passing drilling fluid through the hydraulic hose assembly (18), the interior surface of the cylindrical pipe section (12) is not exposed to the drilling fluid and does not need to be treated to prevent corrosion. Further, the reduced volume of the hydraulic hose assembly (18) relative to conveying the drilling fluid through the interior of the cylindrical pipe section reduces significantly the waste of drilling fluid, allows the fluid to be pressurized more rapidly to initiate drilling operation, and limits fluid spill damage to the environment. A rigid or flexible tube can replace the hose assembly (18), with the tube attached to the ends by threads, seals, press fits, O-rings or adhesives, or any combination thereof.

Abstract: Purpose : An optical waveguide fiber which is made substantially bend resistant.   Constitution : A core having a central region with a higher index of refraction than an integral surrounding region is joined for a segment of its periphery to a clad member, so as to leave a gap between core and cladding. 
     Bend resistance improvement begins when a relatively small fraction, for example, about half, of the core member periphery is detached. A detachment percentage between about 50% and 99.9% of the core member periphery should be achieved, with the preferred range between about 95% and 99.9%. 
     Waveguides include single mode, multimode and polarization maintaining waveguides. Additional core isolation from external forces is provided by an additional semi-detached cladding layer. Only a segment of the periphery of core member (6) is fused to clad (8) along the length of waveguide (5). Also, only a segment of the periphery of clad (8) is fused to clad (10) along the length of waveguide (5). The gaps (7) and (9), which are present along the length of waveguide (5), serve to provide a double isolation of core member (6) from external forces. That is, the stress fields set up in clad layer (10) are only partially transmitted to clad (8), because of the limited contact between the two clads. Likewise, stress fields experienced by clad (8) cannot be fully transmitted to core member (6) due to the limited area of contact between these two waveguide parts. The area of attachment between core member (6) and clad (8) may occur at any part of the inside surface of clad (8). Also, the orientation of the area of attachment between clad (8) and clad (10) may occur at any part of the inside surface of clad (10). In general, the area of attachment of clad (8) to clad (10) and the area of attachment of core member (6) and clad (8) do not influence one another.

Abstract: A current throttle resistor external to a contactor device protects an electrical power distribution circuit coupling a load to a power line. The contactor has electrical switching contacts in series with the load and the line, and for example, an electromagnetically controllable switch for opening the contacts. A current sensor is coupled to the controllable switch for opening of the contacts upon occurrence of a high current fault in the power distribution circuit exceeding a predetermined threshold. A resistive element in series with the power distribution circuit between the line and the load, provides a voltage drop for limiting current during the high current fault. The resistive element can be a nichrome strip or similar positive temperature coefficient resistance having a low cool resistance, and is thermally isolated from the controllable switch by mounting in a resistor housing external to the contactor. To maximize resistance and minimize space, the nichrome strip is bent in an elliptical arc between two leads that protrude from the resistor housing, for coupling into the circuit on the load side of the contactor.

Abstract: The rotor 2 of a rotating field type turbine generator is provided with slots 3 for accommodating the field windings, wedges 4 positioned at the portions of the magnetic poles on the rotor 2 for holding the field windings and wedges 5 positioned between the magnetic poles on the rotor. These wedges 4 and 5 are constituted by metal bars without joints to enhance damper effect thereby. Magnetomotive forces due to higher harmonics, which causes temperature rise of the rotor 2 and torque ripple during starting with thyristors, induces an elliptic rotating magnetic field having the longer diameter on d axis extending in the direction of magnetomotive force induced by the field windings and the shorter diameter on q axis perpendicular to d axis, and thus a larger eddy current is induced flowing along q axis on the rotor 2 than that flowing along d axis. Therefore the thickness d' in radial direction of the wedges 5 positioned between the magnetic poles on the rotor 2 is determined larger than the thickness d in radial direction of the wedges 4 positioned at the portions of the magnetic poles on the rotor 2 to reduce the resistance of the wedges 5 and to easily lead the eddy current flowing in the axial direction of the rotor 2, thereby a good thermal balance over the entire portions on the rotor 2 is achieved.

Abstract: An integrated circuit includes a digital signal processor (DSP) (e.g., 101) and an error correction co-processor (ECCP) (e.g., 113) that implements a Viterbi decoding function. The DSP and ECCP share a block of multi-port memory (e.g., 116), typically by bus multiplexing a dual-port RAM. When the ECCP possesses the RAM, it inhibits the DSP from accessing that block of the RAM by asserting an EBUSY flag. This technique conserves and optimizes the RAM usage, allowing the DSP and ECCP to advantageously be formed on the same integrated circuit chip.
