Abstract: An electrodynamic loudspeaker (1) has a diaphragm comprising a central part (2) and a peripheral part (3), and a voice-coil device (9, 10) coupled to the central part (2). The ratio S2/S1 complies with the relationship 0.5 </= alpha  mu  rho  &Uml&  S2/S1 </= alpha mu  rho  &Uml&  6, where S1 and S2 are the surface areas of the central part (2) and the peripheral part (3) respectively. The ratio m2/m1 complies with the relationship 0.5 </= alpha  mu  rho  &Uml& m2/m1 </= alpha mu  rho  &Uml&  8 where m1 and m2 are the mass of the central part (2) and the voice-coil device (9, 10) and the mass of the peripheral part (3) respectively. Further, the compliance imposed on the diaphragm by the space (6, 6') defined by the diaphragm (2, 3) and the chassis (4) and/or the magnet system (7) is smaller than the compliance of the diaphragm itself (Fig.1). Thus it is possible to realise a car loudspeaker which has a specific dip in its frequency response characteristic P (Fig. 2a), measured in an anechoic room.

Abstract: A support with one or several ICs for inclusion in an identity or credit card is described. The support consists of a substrate, on the surface of which several contact areas are arranged which are connected via conductor tracks to corresponding connecting points of the IC arranged on the substrate. The IC including the connections to the conductor tracks is protected against mechanical stresses by a cured casting compound. To prevent uncontrolled flowing away when the casting compound is applied, a recess is provided in the hot-melt adhesive layer applied on one side of the substrate, which recess retains the liquid resin during the application and acts as limiting frame. The recess in the adhesive layer is located at least in the area where the IC is to be arranged.

Abstract: The electrochemical parameters that are necessary to calculate the corrosion rate are contained in the harmonic current response to a moderate amplitude sinusoidal voltage perturbation applied to the corroding metallic component (W) in an electrolytic cell (26). The harmonic current response is analyzed at frequencies 1f, 2f, 3f, 4f, 5f and the rectification current response at DC current to the presence of a 20-50 mV AC voltage perturbation at a frequency f. The free corrosion current density, the free corrosion potential and the Tafel coefficients are calculated. The Tafel coefficient is a measure of the exponential dependence at the rate of corrosion in a material. From these data, the dissolution current is calculated, which in turn is integrated with respect to time to yield a cumulative mass loss. The corroding metallic component (W) in the electrolytic cell (26) is supplied a.c. and d.c. current under the control of a microcomputer (12) and the response is analyzed by a frequency response analyzer (10) coupled to the cell (26) through a potentiostat (24).

Abstract: The present invention relates to a removable ball joint, of the type fitted in one operation.

A C-shaped retaining ring (10) partially surrounds the cage and traverses its wall through two slots (13) which open into the channel (5) for the introduction of the ball into its housing, converging towards the outside. In order to avoid the risks of corrosion and to facilitate disassembly, the ring exerts on the cage a force parallel to the axis of the channel at two points (12) situated on either side of the plane of symmetry in the summit region, and it moreover bears on the inner face of the slots (13), for example via bumps 27 provided towards its ends, in such a way that it is not normally in contact with the ball or its journal (2).

Abstract: A cryogenic gyroscope for detecting the angular velocity of a rigid system without reference to an external inertial system comprises a closed rigid casing (1) made of a superconducting material and kept below its critical superconducting temperature, for example, by immersion in a bath of liquid helium. A rotation-detector device (20) is situated within the superconductor casing. This device, which is rigidly supported by the wall (2) of the casing, includes at least one component (28) of ferromagnetic material, constituted by a plurality of ferromagnetic strips intercalated with layers of electrically-insulating material, as well as a SQUID magnetometer (31) which is associated with the component of ferromagnetic material for emitting signals indicative of the magnetisation of the ferromagnetic component as a result of a rotation of the casing. This magnetisation is the net result of the magnetisation which occurs in the ferromagnetic element directly as a result of its rotation by the so-called Barnett effect, and the magnetisation derived from the magnet field which is created within the casing due to the fact that the casing is also magnetised as a result of its rotation. By virtue of the fact that the superconducting material of the casing and the ferromagnetic material of the detector device have different gyromagnetic ratios, the net magnetisation of the ferromagnetic component is other than zero and is related to the angular velocity of the rotation of the casing. The measurement of this magnetisation by the SQUID magnetometer thus enables a measure of the angular velocity of the rotation to be derived. Any magnetic fields existing outside the superconducting casing (1) have no effect on the magnetisation of the ferromagnetic component within the superconducting casing since the latter screens such magnetic fields by the so-called Meissner effect.
