The invention relates to a connecting housing (10a-d) for at least one optical fibre, that comprises bearing means (60a, 60b) for at least one optical fibre turn.

A first winding (85), i.e., a winding of the coil (78) at an edge of the coil, has a certain first winding diameter (d1) and a certain first winding distance (a1) from the next winding.

Each of the end-turn members of the second axial layer is connected to one of the winding members and to each of the end-turn members of the first axial layer of end-turn members.

Wherein, at least one turn of the second helical member is disposed proximate at least one turn of the first helical member.

The volume of the working chambers is modified by displacing a mobile turn relative to another mobile turn at a relative speed which is lower than the own speed of the turn displaced in this direction.

A buried n-type loop disposed below the first turn and below the surface of the substrate shields the first turn from the capacitive effects of the substrate.

The antenna of the reader (16) consists of a small-sized convolution disposed in a series with a large-sized convolution, which are concentric and which have the same winding direction.

Each quadrature coil includes a first loop portion disposed on a first surface of the substrate and a second loop portion disposed on a second surface of the substrate.

The coil of rope can be formed as a single coil or a plurality of substantially concentric coils preferably from a single length of refractory rope.

A flattened end portion (70) of flighting is added to the conventional auger flighting (66) at the output end of an auger separator (40).

Each involute spiral wrap is provided with a tip seal (167, 168) in the other axial end thereof which engages with the wrap support plate of the scroll element.

The magnetizing coils (C21-C24) are arranged in an inspecting coil (C1).

A capacitance of a first group of capacitors located outside a turn of an inductor is roughly equal to a capacitance of a second group of capacitors located inside the turn.

An improved turn-to-turn short circuit detection device of transformer via differential voltage comprises a single-phase transformer (TM).

In the mounted state, the lower end and the lower end turn are substantially in contact with each other at one lower contact point on the lower end turn.
