Abstract: 1,096,531. Wheel detectors. SOCIETE IN. DUSTRIELLE DE LIAISONS ELECTRIQUES. Jan. 13, 1965 [Jan. 15, 1964], No. 1447/65. Heading B7N. [Also in Division G1] Means for detecting the presence and/or passage of a metallic mass, e.g. the wheel of a railway wagon, comprises in a position adjacent a rail 8, a pair of coils 2, 2<SP>1</SP> energized from A.C. source 6 such that in the absence of a wheel the magnetic fields generated by the coils cancel in a detector coil 18 positioned in the return flux path of the coils and a phase detector 19 with its inputs connected across coils 2 and 18. A wagon wheel 22 between coils 2 and 18 unbalances the return flux in coil 18 and the resulting voltage, compared in phase with the voltage across coil 2 in detector 19, produces a detector output of a particular polarity. When the wheel is in a position between coils 18 and 2<SP>1</SP> the phase of the resulting voltage changes by 180 degrees and the detector provides an output of opposite polarity. Both inputs to the phase detector may be connected via amplitude limiter circuits. In a second embodiment, Fig. 7 (not shown), two detector coils are provided, each mounted with one of the coils 2, 2<SP>1</SP> on a U-shaped coil having its base parallel to the rail. The detector coils are connected in opposition to the detector input. The arrangement may be employed as an axle counter which also indicates the direction of wagon movement, or can be used, Fig. 6 (not shown), as a means for indicating whether a road vehicle parking position is occupied.

Abstract: 283,961. Siemens - Schuckertwerke Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). Jan. 22, 1927, [Convention date]. Alternating - current induction machines.- In an arrangement for generating alternating- current by means of an asynchronous generator driven by a Diesel or other reciprocating engine giving a variable torque the generator is cascaded with a commutator machine so excited that it introduces into the secondary circuit of the generator carrying the slip frequency two voltages, one of which is proportional to the slip of the asynchronous generator and cancels its slip voltage wholly or in part while the other is independent of the slip of the generator and produces the load current in the secondary of the generator circuit in the manner described in Specification 283,957. In the arrangement shown, the asynchronous generator 1, driven by a Diesel engine 3, is cascaded with a commutator machine 2 rotor-excited by two voltages, one from a line transformer 14 and one from a statorfed commutator shunt machine 12 mechanicallv coupled to the generator 1. The machine 12 excites the machine 2 so that it produces a voltage equal and opposite to the slip voltage of the main machine 1. The second component is constant and gives a current in the rotor of the generator 1 independent of the slip and therefore producing a constant power output from the generator. Bv adjustment of the transformer 14, the output of the generator may be brought up to the maximum output of the engine.
