Abstract: In a method for producing a portable electronic device with an integrated circuit, a resin band is deposited around the chip of an integrated circuit and connection wires. The resin is highly viscous and can be polymerized with U.V. radiation. A low-viscosity filling resin which can be polymerized with U.V. radiation is deposited in the space defined by the resin band, and the protected resins are polymerized by exposure to U.V. radiation. The filling resin contains mechanically reinforcing fibers. The entire process can be carried out in a continuous manner.

Abstract: The redundant regulation valve for controlling fluid flow comprises a valve body defining a passage for the flow of the fluid, a main throttle element movable by means of a main control device to selectively obstruct the passage, and a redundant throttle element movable by means of a redundant control device. When the valve is in its closed position in normal operation, the main element and the redundant element are in contact with each other. In this normal closed position, the main element is close to its fully-extended position in the closure direction and it obstructs only about half of the passage, while the redundant element is in a position of medium extension. The stroke of the redundant element is such that the redundant element can be controlled to obstruct the entire passage even when the main element is in its fully-open position.

Abstract: An arrangement for mounting two bearings supporting a shaft within a housing, each bearing having an inner race secured to the shaft and an outer race, the arrangement comprising two annular membrane-shaped spacer members having a high radial stiffness and a predetermined axial flexibility, the spacer members having an outer edge and an inner edge, the inner edge of each spacer member being secured to the outer race of a respective bearing and the outer edge of each spacer member being secured within the housing, both spacer members being subjected to a predetermined amount of axial deformation with respect to their unstressed condition, whereby the spacer members exert a precisely determined axial preload onto said outer races of the bearings.

Abstract: The invention relates to a method and devices allowing exchange of data between authorized bearers of crediting means (1) to be identified, approved and possibly coded and to remote centralized processing machines (3) via specific terminal units (2). The data produced by a bearer of a crediting means (1) after connection of said means (1) to a terminal unit (2) and sending of the identity of said means (1) are approved by a logic generation unit (15) of the means (1) from an individualization code and from transaction data. The invention applies to the exchange of data in an insecure environment and more particularly to bank credit card systems.

Abstract: A rotor centering device comprising two radial bearings each one constituted of first and second opposing members with angular contact races, mounted with axial clearance so that if one of the said members is in abutment, the other member has a radial clearance. The first angular contact centering members of the first and second bearings are also opposing, and the second angular contact centering members of the first and second bearings are likewise opposing, so that by relative axial movement of the inner and outer contact races of both first and second centering means belonging to the two bearings, simultaneous contact of the inner and outer faces is achieved either with the first centering members or with the second centering members which happen to be opposing on the two bearings.
