Abstract: The invention relates first to compounds consisting essentially of a functionalised organosilane of formula (R1O)a(R2)3-aSiZ, wherein R1 and R2 are monovalent hydrocarbonated groups, a is a number chosen from 1, 2 and 3 and Z is a function containing an activated ethylenic double bond, chosen from the following:an ester-maleamic function and/or an ester-fumaramic function. The invention also relates to methods for producing said compounds, and to their use as white filler-elastomer coupling agents in rubber compositions containing a white filler, especially a siliceous white filler, as a reinforcing filler.

Abstract: Device for testing a network of components, in particular an electronic circuit.The respective potential differences between the terminals of the circuit to be tested are acquired during a chosen time interval and stored in a values memory. A memory contains predetermined functional models of electronic components. The processing means, connected to these memories, are capable of effecting a processing comprising the estimation, during said time interval, of physical values, notably of current-expressions, taking account of expressions contained in said acquired models and values, and storing them in the values memory as well as tests on the values contained in the values memory.

Abstract: The present invention relates to a device for controlling the dimensions and spaced-apart relationship of rigid pieces disposed in a bundle. Said device comprises: two supple probes adapted to transmit a light beam and insertable between rows of pieces so as to surround one of these rows; means for positioning and displacing these probes; a source of light emitting a light beam transmitted by the first probe then picked up by the second transmitting it to a photodetector producing an electrical signal; electronic means for processing this signal, furnishing information making it possible to control, from reference values, the dimensions and spaced apart relationship of the pieces, due to the modulation of said signal, provoked by the successive occultations of the light beam by the pieces, during the displacement of the probes along the row of pieces. The invention is applicable to the control of the pencils of a fuel assembly of a nuclear reactor.
