Title: Method and apparatus for analysing meteorological variables applicable in particular to the optimising of agricultural production
IPC: G06F19/00
Filed: 1984-11-07
Abstract: The apparatus relates to a method for computing the sum of average temperatures which are greater than a threshold and the sum of the daily precipitations between two given dates. This method is implemented with a single apparatus recording the maximum and minimum temperatures, and the daily precipitations over at least one year, by means of a temperature probe 6, a converter 7, a rain sensor 8, an input/output port 9 and a microprocessor 1. The user can, via the keyboard 4, obtain on the display 5 the meteorological values for one day or the result of a sum. The apparatus according to the invention is particularly intended for agricultural production especially for the application of nitrogen at the start of growth of vegetation or to determine a date for harvesting maize.

Title: Retention system for cross-country ski
IPC: A63C7/00
Filed: 1985-03-07
Abstract: Retention system for cross-country ski. The invention relates to a device making it possible to retain or to stop the backsliding of a pair of cross-country skis without waxing problems and which permits perfect gliding of the running sole. It consists of claws 3 having a profile 12 ensuring retention, which claws 3 are mounted in an elastic system 2. A cam 1 comes into contact with the heads 5 of the claws. This cam 1 forms part of any binding 8, fastening any boot 9.

Title: Improved quartz tube for thermal treatment of semiconductor wafers
Inventor: BOUTAULT JOEL
IPC: C30B31/10
Filed: 1986-10-30
Abstract: This tube process 22 consists essentially of a smooth cylindrical tube 23, which is open at a first end and closed at the other end, with the exception of two openings 26a, 27a, which are each extended by a projecting part 26b, 27b. On the first projecting part 26b, a PTFE connector 31 is fitted, which is passed through by a pipette 34 for injecting gases. A second PTFE connector 42 is fitted on the second projecting part 27b, and is passed through on the one hand by a pipette 37 for draining the gases, and on the other hand, by the thermocouple jacket 38. These parts are situated in a maintenance passage 28. The tube process also comprises a ring 39 which is fitted in a leaktight manner onto the part of the tube which extends from the diffusion oven 30 and is situated in the clean room 25. The atmosphere in this room is controlled, in order to have high purity. This ring comprises an endpiece for connecting up the nitrogen which insulates the inside of the tube process with the said controlled atmosphere. It also comprises means (a vacuum channel connected to a vacuum source) for receiving a door 45 which closes the tube process in a leaktight manner. The design of this tube process allows the diameter of the processed wafers to be increased, facilitation of cleaning and reduction of breakage. Furthermore, it can be assembled/disassembled from the maintenance passage, it thus reduces the risks of contamination of the clean room as well as the volume required in the latter.

Title: Dispositif de protection contre des effets des impulsions electromagnetiques nucleaires
Inventor: BROYDE FREDERIC
IPC: H01H77/10
Filed: 1988-06-28
Abstract: Le dispositif de protection d'une ligne d'énergie électrique basse tension contre les surtensions dues aux impulsions électromagnétiques d'origine nucléaire est constitué d'un contact limiteur 12 inséré dans la ligne et d'un éclateur à gaz 14 connecté entre la ligne et la terre. L'éclateur à gaz s'allume dès l'apparition de la surtension impulsionnelle après quelques nanosecondes et provoque un court-circuit qui engendre l'ouverture du contact limiteur 12. Dès l'interruption du courant, le contact limiteur se referme en rétablissant l'alimentation, la durée d'ouverture du contact limiteur étant suffisante pour l'extinction de l'arc dans l'éclateur, évitant tout réamorçage lors du rétablissement de l'alimentation.
