Patent FR-2621204-A1 (FR)
Title: Procede et dispositif de cryptage/decryptage analogique d'un signal video analogique
Inventor: FERRERO PAUL
IPC: H04N7/171
Filed: 1987-09-24
Abstract: Le procédé de cryptage/décryptage analogique selon l'invention s'applique à un signal vidéo analogique S comportant un signal utile SU relatif aux lignes de l'image, entrecoupé d'intervalles de retour-ligne IRL. On fait subir à des parties disjointes du signal utile SU une inversion en fonction d'une suite d'informations binaires choisie, possédant une allure sensiblement aléatoire, et l'on obtient un signal vidéo inversé SI. On peut également ajouter à ce signal SI un signal perturbateur SP tiré d'au moins une forme d'onde, choisie, quasi aléatoire. Afin que le signal de sortie soit dans un gabarit normalisé, on peut effectuer une compression du signal vidéo et l'on obtient alors finalement un signal crypté SCR. Le procédé de décryptage consiste à effectuer des opérations inverses du cryptage.

Title: Circuit for measuring and digitising the value of a variable resistor, such as a thermistor
Inventor: RAFFRAY PATRICK
IPC: G01R27/02
Filed: 1989-03-17
Abstract: The circuit comprises a microprocessor MUP with its data memory RAM, its clock HOR, a counter COM, its interrupt input INT, and three three-state output ports P1 to P3. The interrupt input INT is connected in parallel to earth through a capacitor C, to the first port P3 through the variable resistor RT, to the second port P2 through a fixed resistor RO the value of which corresponds to a specific value of the variable resistor, and to the third port P1 through a second fixed resistor RE the value of which corresponds to the variation in the variable resistor RT between two predetermined values. The three ports are initially at earth potential and the counter is at zero. Each port from the first P3 to the third P1 is in turn set to the positive potential Vcc, while the other two ports are switched to a high impedance HI and while the counter COM of pulses H from the clock HOR is triggered. The charge on the capacitor C produces an increase in voltage at the interrupt input INT which, when it reaches the value of the interrupt signal, causes the counter to stop and earths the three ports. The content of the counter is then transferred to the memory RAM. The first content obtained is then subtracted from the second content obtained and the result of this is divided by the third content obtained and multiplied by the difference between the said predetermined values in order to obtain the digitised value of the variable resistor RT.

Inventor: PHILIPPE BLIN
IPC: B22D11/06
Filed: 1989-06-26
Abstract: Cassette (3) for a device for continuous casting of molten metal between two parallel rolls (2), comprising a casing (4) which is open on one of its sides, containing a plate (5) of refractory material which can be preheated before casting of the molten metal; the refractory plate (5) is preformed so as to reserve a free space (8) between its periphery and the wall (4b) of the casing (4), and this cassette is equipped with means (9, 11) for fastening and clamping the plate (5), with elastic antagonistic action permitting free expansion in the casing (4) of the plate (5) during its heating up. The free expansion of the refractory (5) prevents any bulging or bending of the latter and of the assembly of the cassette (3), and thus ensures maintenance of sufficient leaktightness to avoid any risk of infiltrations of molten metal between the front faces (2a) of the rolls (2) and the refractory plate (5).
