Abstract: The four elements are each provided with protrusions constituted by forks the branches of which are resilient, which are each provided with a recess and with an embossment. These protrusions engage with each other, their embossments and their recesses hooking each other, and are thus articulated to each other around rotation axes. The series of protrusions and of the free spaces which separate them are determined in such a way that the four plates can be articulated to each other two by two, that has for consequence they can be articulated all the four to each other. With respect to a central axis, the half-series of each element are not symmetrical but they can be identical.

Abstract: Four elements are each provided with protrusions constituted by forks, the branches of which are resilient. Each fork is provided with a recess and with an embossment. The protrusions engage with each other, their embossments and their recesses hooking each other, and are thus assembled to each other around rotation axes. The series of protrusions and of the free spaces which separate them are arranged in such a way that the four elements can be articulated to each other two by two, that has for consequence they can be assembled together by engagement of the protrusions of any one element with those of another element. The protrusions on respective halves of each element are not arranged symmetrically, but they can be identical.

Abstract: Process for managing concurrent access permitting the successive input or storage of several slave devices (receiver/transmitter) in the field of action of a master device (emitter/reader) so as to render possible the exchange of data in two directions whilst guaranteeing coherent transmission between the master device and each slave device. This process is based on a double temporary address of the slave devices. Upon each command emitted by the reader, two values are transmitted, the first comprising the identification of the next free number and the second the number of the receiver to which the command is directed.

Abstract: Regular rhombic dodecahedrons having faces with two aspects of two different kinds, each belonging to a same family, one by a bare surface, the other one by a shaded surface, are piled on a base having nests allowing those polyhedrons to be placed on top to build a composed pyramid. The general configuration of the visible faces of one kind and of the other kind will respond to specific rules of the game.

Abstract: Device for the alignment of a part 12 and of a substrate 10 designed to receive it. The device contains a plate 2, on the horizontal flat upper surface 3 of which an XY table 5 can slide, a blocking device 16 for temporarily interrupting any translation of the XY table 5, but leaving it free to rotate on a given vertical axis 4, a gripping device 11 and an optical viewing device 15. The blocking device 16 preferably consists of an electromagnet mounted for rotation in a bore of the plate 2.

Abstract: A horological device is provided with an alarm switch in the form of an alarm wheel having a conductive path extending from a topside of the wheel to a bottom side of the wheel. The alarm wheel is adapted to operate in an alarm circuit arranged to generate audible signals at a predetermined time. An alarm setting pinion is engaged with the alarm switch to prevent undesired movement of the alarm wheel in case of mechanical shock.

Abstract: A circuit for providing an audible alarm, capable of having a characteristic sound. The acoustic/alert circuit includes a battery and a self-starting voltage multiplier including a capacitor which provides a higher source of voltage to power an associated binary counter and transducer element as well as providing a source of input frequency to the binary counter. The input frequency signal drives the binary counter with its plurality of fractional frequency outputs. At least two of these fractional frequency outputs are used in combination with logic circuitry to generate a modulated complex signal to a gated oscillator means which includes a sound generating transducer.
