The invention also provides improved methods of forming the spirally wound yoke.

The invention also provides improved methods of forming the spirally wound yoke.

A spirally wound electric motor yoke of generally polygonal cross-section has part-cylindrical surfaces (58) machined for receiving mating bosses (60) of an end member (59) to provide improved concentricity.

At least one turn of the cathode from the end of the wound anode is further wound.

Winding takes place as the bobbin (2) is being automatically changed.

The bolt carrier system includes a bolt and a bolt carrier.

The invention relates to a rocker arm frame (1) for a cylinder head of an internal combustion engine, which is mounted on a bottom part of the cylinder head and on which a cylinder head cap is placed.

The cylinder head assembly includes a cylinder head (170) and a component (520) coupled to the cylinder head (170).

A device may include a cascaded coil antenna to include a first coil antenna that is connected in series with a second coil antenna.

The yoke segments define a yoke in the form of a polygonal figure and in the preferred embodiment the stator (1) comprises four yoke segments and four pole piece segments.

The yoke (7) has at least one yoke member (15).

A cylinder head has a head-side discharge section.

Each of the stators comprises an inner yoke and an outer yoke.

The construction reduces processing cost of a cylinder head, makes the cylinder head compact, and simplifies the structure of the cylinder head.

An interferometer (50) includes the first spiral-wound optical fiber coil (14) in a first leg and the second spiral-wound optical fiber coil (16) in a second leg.
