    Abstract: A circuit for inverting a number of n bits of a finite field of 2.sup.n =N+1 elements comprises a first circuit for raising to the power t=2.sup.n/2 receiving the number to invert. A first complete multiplier receives the number to invert and the output of the circuit for raising to the power t. A second circuit provides the product of the output of the circuit for raising to the power t and the inverse of the output of the first complete multiplier.

    Abstract: The industrial installation comprises an active zone (III) with which there are associated means for measurement and for command and a control position (I) separated from the active zone. Means for measurement, for control and for command (15) located in the active zone are supplied with luminous radiations, from the control position, through an optical fibre (8) joining the active zone to the control position. Radiation having a broad spectral band is emitted in the fiber (8) from the control position (I) and then divided in order to obtain unitary radiations for supplying each of the means (15). The invention applies to nuclear reactors.

    Abstract: Being given the number among P of a data, an attempt is made to find the number among N of said data in a group of N data incorporating P selected data. The sequence numbers of these P data appear in a register having N locations and the sequence number of the chosen data among P appears in a second register with P locations. The locations of the second register are connected to the rows of a switching circuit, each of these rows having N cells, which connect the input of one cell to the following cell of the same rank or to the following cell of the lower rank, as a function of the content of the corresponding location of the first register. Thus, at the outputs of the columns there are signals, whereof only one is at a level different from the others and corresponding to the number j among N of the chosen data.
