An inductive transducer includes first and second relatively movable members, the first relatively movable member having a plurality of windings and the second relatively movable member having a winding. The windings of the first relatively movable member each have a pair of terminals and are each arranged in a pattern comprised of a first section coupled to one of the terminals and a second section coupled to the other terminal and to the first section. Each section includes a plurality of cond...

An inductive potentiometer for supplying a d.c. output voltage, which is linearly variable as a function of the rotation angle of a spindle. The potentiometer is constituted by a synchro-resolver and two associated circuits, an a.c. voltage supply circuit of one stator winding incorporating an oscillator whose amplitude is controlled by the supply voltage and an output circuit connected to the rotor which incorporates a demodulator stage. The linearization of the voltage as a function of the ang...

A sensor which conveys a displacement of an object into a change of inductance with which associated circuitry can be used for monitoring the displacement of the object. The sensor includes a coil maintained about a housing in which is disposed a ferromagnetic core about which is disposed a sleeve made of a conductive material and movable between the core and the coil with the induction of the coil variable in accordance with a predetermined relationship to the displacement of the sleeve with re...

An inductive, frequency generator having first teeth-like protrusions provided in at least one of two first annular regions of a magnetically excited stator one of the first annular regions being divided into at least two arcuate portions. Further substantially identically shaped teeth-like protrusions are provided in at least one of two further annular regions of a rotor. The rotor and stator are positioned close to one another with their respective annular regions and teeth-like protrusions op...

An inductive component having a central core comprises two stacks of U-shaped laminations disposed side by side so that the adjacent limbs constitute the central core. The outer limbs of the two stacks are bent towards the central core with the laminations at the ends of the outer limbs parallel to those of the central core.

An inductive device comprises a soft magnetic core which consists of two E-shaped core halves (1), each of which comprises three parallel limbs (5, 7) which are interconnected by a yoke (9). The core halves (1) are arranged against one another by way of the free ends of the limbs (5, 7), a coil former (3) being provided around the central limbs (7). The outer limbs (5) extend between an upper boundary plane (25) and lower boundary plane (27), which planes extend parallel to the longitudinal dire...

A coaxial inductive coupler having an inner magnetic core member and a surrounding outer magnetic core member each having respective windings. The inner magnetic core is operatively carried by an inner support assembly which is additionally connected to an outer protective shell. The outer core is disposed within a cylinder having at the end thereof a large guide member for facilitating insertion into the outer protective shell. A locking mechanism is provided to insure positive coupling and eas...

An inductive connector has two coils which are inductively coupled when the two parts of the connector are "connected." Associated with one of the parts is a third coil which is movable, normally automatically, into inductively coupled relationship with the other coil of that part when the parts are separated. An impedance is connected in circuit with the third coil, whereby impedance matching with a source connected to the aforesaid other coil of that part can be achieved when the parts are sep...
