Title: Continuous supply and automatic level regulation system, using rigid refills with flow of liquid for chamber or tank for atomising essential oils
IPC: B05B7/00
Filed: 1986-04-04
Abstract: Continuous supply system for atomising tanks or chambers. The invention relates to a device using rigid refills with slow flow (of the bottle with dropper cap type) which allows continuous supply of an atomising tank such that the system can operate with a small quantity of liquid. It consists of a receptacle 4 intended to receive the refill, connected by a tube 5 to the lower part of the atomising tank. The receptacle is fitted with a support 6 or a shoulder 7 adapted to the type of bottle used and allowing flow of the liquid when the level is sufficiently low. The tube and the bottom of the receptacle are very slightly inclined with respect to the horizontal so as to allow complete atomisation of the liquid. When the level falls in the tank, air may be introduced into the bottle which allows a certain quantity of fluid to flow, whose level is stabilised at the base of the bottle. The device according to the invention is in particular intended for supplying essential oil atomisers.

An intermediate mass 3, which thermally protects the contents, contributes to the cohesion of the whole and acts as a shock- and vibration-damper.
Patent FR-2597988-A1 (FR)
IPC: H03K17/969
Filed: 1986-04-25
Abstract: A matrix-scanning optical keyboard comprising a logical matrix of optical paths between light inlets (3) and outlets (2) with keys disposed on each optical path connecting an inlet to an outlet in such a manner that depressing a key causes a change which can be detected by a scanning driver circuit connected to the light inlets and outlets in order to respond to changes affecting each inlet-to-outlet (3-to-2) coupling by periodically injecting an interrogation signal into each inlet in turn and by inspecting each outlet for the presence of possible changes. The keyboard is capable, for a given emission level, of increasing the sensitivity of the driver circuit to light arriving at the outlets.

Patent FR-2610684-A1 (FR)
IPC: F16H3/74
Filed: 1987-02-10
Abstract: Mechanism adapting automatically and constinuously the stepping-down ratio to the engine torque/charge torque ratio, solely by means of the natural meshing of a pinion system, with spur-toothed and conical, simple and double toothing. The toothing of all the gears is determined in such a way that when the planet wheel (11) ceases to rotate, the gear slips of the differentiated planet wheels (3, 7), relative to the rotating speed of the driving shaft (1) are of the same value, one positive, the other negative. When the reaction torque at the output is lower than the driving torque, stability is regained by reducing the stepping-down until the output torque equalizes that of the input (direct drive). Application of mechanism as fitting to any dynamic machine, particularly to provide automobiles with continuous variation trans mission.

Patent FR-2611039-A1 (FR)
IPC: G01C19/66
Filed: 1987-02-18
Abstract: A device for eliminating parasitic rotations of the mobile mirrors (15) of gyrolasers driven by piezoelectric ceramics (11). These parasitic rotations are caused by deformations of the external part (12) which constitutes the body of the mobile mirror and is attached to the optical block (1) under the effect of the accelerations of the activating motion. These parasitic rotations are corrected in the invention by semi-circular ceramics (26) glued around the external part (12), which, when driven by an electronic circuit, correct the deformations of the said external part (12). The invention is applicable to all lasers and in particular to gyrolasers.
