Abstract: An optical fiber coil for a fiber-optic measuring device and a method for producing it. An opitcal fiber is applied to a winding body in a quadrupole winding pattern in directly successive winding layers such that the turns of the individual winding layers have, at irregular spacings, as large a number of crossover points as possible. The spacings between the individual turns in each winding layer are variable, but, on average, they correspond to approximately half the diameter of the optical fiber. The optical fiber coil is preferably applied to the winding body without the use of fixing and buffer means.

Abstract: In order to reduce the sensitivity of a fiber-optic sensor coil to temperature transients along the optical fiber (4) of the coil, and thereby to reduce reciprocity errors produced in the case of fiber-optic Sagnac interferometers, the invention proposes the application of the optical fiber (4) to a winding body (1) in a quadrupole winding pattern in directly successive winding layers such that the turns in the individual winding layers have at irregular spacings, as large a number of crossover points as possible. The spacings between the individual turns in each winding layer are variable, but on average they correspond approximately to half the diameter of the optical fiber. The optical fiber coil is preferably applied to the winding body without the use of fixing and buffer means.

Abstract: A YZ-latch for holding down a piece of freight on a loading floor in an aircraft which has a base holding an axle stub which in turn has mounted thereon two rollers for rolling contact with the freight piece. One roller holds against lateral displacement in the Y-direction. The other roller holds against vertical displacement in the Z-direction. Free movement is permitted in the X-direction. Either the axle stub with fixed rollers is rotatable, or the rollers are rotatable on the fixed axle stub, or at least one roller or both rollers are rotatable on a rotatable axle stub.
