  • Device for winding and unwinding a cable around a drum
    Patent number: 10023280
    Abstract: A device for winding and unwinding a cable including a winch comprises a chassis, an electric motor for driving a drum in rotation in relation to the chassis, locking/unlocking means comprising a first induction coil and configured such as to immobilize the drum in relation to the chassis when the first coil is not being powered electrically, the device including a second induction coil that is powered electrically, dimensioned and arranged such that the magnetic field generated by the assembly formed by the first and second coils, when the first coil is powered electrically, is less than the magnetic field generated by the first coil at a point located at a distance from the winch that is greater than a predetermined threshold, the electrical energizing and de-energizing of the second coil being synchronized with the electrical energizing and respectively de-energizing of the first coil.

  • Organic material with extremely narrow electron spin resonance line and gaussmeter probe or magnetometer using this material
    Patent number: 5070214
    Abstract: Disclosed is an organic material with a very narrow electronic spin resonance (ESR) line. This material is formed by a 1, 2, 7, 8-tetrahydrocyclopentataperylene salt which may have, advantageously, undergone a heat treatment. The material can be applied to the fabrication of probes for gaussmeters and magnetometers.

  • Process for preparing polyalkyl perylenes, perylenes obtained by this process, and organic materials with ESR properties derived from the same
    Patent number: 4956508
    Abstract: The invention relates to a process for preparing a polyalkyl perylene which consists in subjecting the corresponding polyalkyl 1,1'-dinaphthalene derivative to a cyclodehydrogenation reaction, by means of an alkali metal. It also relates to the polyalkyl perylene obtained, and to the organic material derived therefrom exhibiting an electron spin resonance spectrum.
