Title: Spraying control device using closure of a door.
IPC: A61L9/14
Filed: 1984-08-02
Abstract: The invention relates to a device allowing a liquid to be sprayed by using the movement of a door as the driving force. It is constituted by a liquid tank surmounted by a sprayer, fixed to the frame of a door, or to the wall surmounting this frame or even to the frame and the wall. The device mounted on the door bears on the piston of the sprayer when the door closes thus providing the spraying of the liquid at each closure. For aesthetic reasons, the part fixed to the door is also used as a coat hanger and the one fixed to the frame is used as a shelf.

Title: Valved metal-spraying micro-torch
IPC: B05B7/20
Filed: 1984-09-19
Abstract: The present invention is in the field of techniques implementing the melting of metals by virtue more particularly of a gun intended for spraying molten metal. A gun, comprising a container 5 of metal powder 6 and a conduit 2 for blowing a gas, is principally characterised in that the means for the temporary relationship of the container and the conduit are of the type having a valve 10, constituted by a rod 11 which traverses the container and which is controlled by direct finger pulsing on the deformable and removable membrane 15 blocking off the upper orifice of the container. Application to the welding of small workpieces such as pieces of jewellery or of dental work.
Patent FR-2570786-A1 (FR)
Title: Automatic speed variator with dynamometric reflexes
IPC: B60K17/04
Filed: 1984-09-26
Abstract: The object of the invention is to automate or program the speed variations which are generally obtained by a reducer, multiplier or gearbox. In the device the pinion 11 drives the gears 7 and 9 which due to their twinning with 6 and 8 drive the pinion 10. If the rotor 3 is immobilised, the pinion 11 transmits the whole of its nominal speed transformed by the twinned pinions to the pinion 10. If under the influence of the motor 21 the rotor 3 withdraws in one direction or the other, the gears 6 and 8 lose their bearing points thus leading to a loss of their driving function. At a certain speed of 21 their effect becomes nil. If, exceeding the nil point the speed of 21 is increased, the movement of 10 becomes negative, the angular movements of 21 can be programmed or receive information from the dynamometer 41 and the variator is sensitive. The invention applies to all machines, plant, vehicles which use variable speeds.

Abstract: Dans celle-ci on esquive les fraudes en fabriquant, d'une manière interne à la mémoire, les différents potentiels qu'elle utilise pour vérifier des points mémoire choisis. La vérification de l'écriture d'une information dans un point est obtenue en soumettant ce point à une tension de sélection calibrée, sur laquelle un opérateur extérieur ne peut avoir accès. Cette tension calibrée est procurée par un générateur-multiplicateur (14). Celui-ci débite dans un ou plusieurs calibrateurs (18) pour fabriquer toutes les tensions utiles. Des ordres de lecture et d'écriture sont alors donnés à un circuit de commutation (47) qui provoque l'application correspondante de ces tensions calibrées. Un opérateur extérieur ne peut pas entrer dans la mémoire des signaux falsifiés en niveau pour modifier la signification du contenu des informations enregistrées.
