Title: Appareil pour mesurer l'amplitude d'un signal optique, et pyrometre comportant un tel appareil
Inventor: JOHN LAURENCE NICHOLAS
IPC: G02B26/04
Filed: 1990-08-02
Abstract: L'appareil concerne un appareil optique pour mesurer l'amplitude d'un signal de rayonnement optique à l'aide d'un détecteur, d'une manière indépendante des variations de température du détecteur. L'appareil comporte une microstructure en silicium 3 ayant une barre 32 qui est mise en vibration par un rayonnement optique provenant d'une source excitatrice alternative 34. La barre 32 bloque et laisse passer alternativement le rayonnement d'une zone optiquement émettrice 1 vers une photodiode 4 formant le détecteur. Un circuit d'échantillonnage 41, piloté par la source d'excitation 34, délivre deux signaux simultanés représentant la présence et l'absence du rayonnement, d'où une indication de la température de ladite zone 1 est tirée par différenciation entre ces deux signaux. Application à la pyrométrie et à d'autres mesures analogiques de rayonnement optique.

Title: Process for the synthesis of new disaccharide compounds without any glycoside link, products obtained by this process and their applications as surface-active medication or chelating agent
Inventor: MAMY FAUVIN
IPC: C09K23/00
Filed: 1993-02-22
Abstract: We have prepared new disaccharide compounds associating, without any glycoside link, two derivatives of oses or of itols A and B, on sites chosen in advance of formula I: The process for the synthesis of these compounds includes especially the stage of linking the units A and B by attack of a derivative of the unit B, in alcoholate form, on an anhydro group derived from the unit A. The products obtained bear, respectively, 0 to 3 ZIFI groups on the unit A and 0 to 3 ZJGJ groups on the unit B, as well as a modulable number of free OH groups which can vary from 0 to 4 (p) on the unit A and from 0 to 4 (p') on the unit B. The units A and B may create a second link by internal cyclisation. One of the groups ZIFI or ZJGJ may be a third unit C analogous to A and B, resulting in trisaccharide compounds. In addition, if the unit C is joined to B, it may also create a link with A by internal cyclisation and if the unit C is joined to A, it may also create a link with B by internal cyclisation. The surface-active, chelating and biological properties revealed by the products obtained are described with a view to applications as surface and/or chelating agents, calcium antagonist medications and antitumour medications.
