Patent WO-8911175-A1 (WO)
Title: Protective power variator
Inventor: AMAURY GEORGES JEAN
IPC: H02H9/02
Filed: 1989-04-21
Abstract: A variator circuit comprises a triac (4) mounted in series with a load (1) to be controlled, and a CTR variable series phase-shifter circuit (8, 9, 10). The point (11) midway between the resistive element (8, 9) and the capacitive element (10) of said circuit (8, 9, 10) is connected to the gate (6) of the triac. Connected in series in the branch of the circuit comprising the resistive element and the connection of said midway point to the triac is a non-linear component (18) the resistance of which can change from a minimum value to a maximum value when the current flowing through it increases by a minimum value corresponding to the normal operating conditions of the phase-shifter circuit to a maximum value corresponding to a short-circuit condition of the triac between the gate and the power electrode, said minimum value of the resistance being a value which has no appreciable effect on the functioning of the phase-shifter circuit and said maximum value of the resistance being a value which limits the current in the resistive element to a value which prevents any destruction or deterioration of the latter. Said non-linear component may be a CTR resistor, a fast safety fuse or, very advantageously, the filament of an incandescent lamp, the characteristics of said filament, in particular its equivalent resistance under nominal operating conditions, being chosen so that it volatilizes in the event of a short-circuit condition of the triac between the gate and the power electrode.

Patent FR-2650604-A1 (FR)
Inventor: AHO OSMO
IPC: D21C1/10
Filed: 1989-08-04
Abstract: The invention concerns a process and an equipment for pretreatment of cellulosic chip-formed raw material by impregnation. In the process, first a vacuum treatment is carried out without preceding moistening treatment, and as soon as possible after the vacuum treatment penetration is carried out with a solution of chemicals or with water at the atmospheric or a higher solution pressure. In this way the fiber cavities can be filled optimally, which promotes a uniform and adequate diffusion of the solution into the fiber walls significantly. The process can be carried out, e.g., in a device which comprises a tank (11) for the treatment of the raw material and therein a feed opening (18) for the solution as well as an opening (14) for removal of the raw material, which said opening (14) communicates preferably with a reception tank, wherein the atmospheric or a higher pressure prevails.

Patent FR-2664182-A1 (FR)
Title: Pompe-doseuse pour pulverisateur sous pression avec securite intrinseque.
Inventor: JEAN-PIERRE LINA
IPC: B05B11/00
Filed: 1990-07-09
Abstract: Une pompe-doseuse à précompression a déjà été montée dans l'art antérieur sur un récipient sous pression. Elle ne sert alors pas tant à propulser le contenu du récipient en vue de le pulvériser qu'à l'isoler vis-à-vis de l'air ambiant afin d'éviter sa détérioration. Toutefois, la pompe en question a jusqu'ici été pourvue d'un ressort 7 tel que ses pistons remontent indépendamment de la pression régnant dans le récipient. Si ce dernier fuit, existe par conséquent le risque d'émettre une dose impropre. La présente invention rend impossible toute pulvérisation sitôt que la pression dans le récipient chute en deçà d'une pression prédéterminée, choisie avantageusement entre 1 et 2 bars au-dessus de la pression atmosphérique. Pour cela, la raideur du ressort 7 est diminuée de façon que la remontée des pistons résulte pour partie de la détente du ressort et pour partie de l'effort transmis par la pression régnant dans le récipient.

Title: Improvement to ultralight or microlight aircraft in terms of the cockpit and the propulsion
Inventor: ALAIN CROS MICHEL LOUIS
IPC: B64C31/028
Filed: 1990-10-23
Abstract: The invention relates to the improvement of the piloting position allowing taking off and landing on foot and cruising flight in stretched-out position; as well as that of the power plant in terms of noise, safety and energy efficiency. The saddle seat (1) allows for the standing position or the stretched-out position. The latter, according to the type of aircraft, may be on the back or face down. A turbine (10) directly engaged with the engine (9) functions within a convergent nozzle (11). In the case of the motorised parapent, the control surfaces are controlled by the rudder bar (8) or by a control column (14). The delta wing can be used in two ways, either in stretched-out configuration on the back with or without a landing gear, or in face-down position suspended from a mast (16) which carries the power plant (17), the saddle seat (18) and a rear footrest (19). This improvement according to the invention is intended particularly for ultralight aircraft with a fixed, flexible or rotary wing. Moreover, it can be extended, especially as far as the propulsion is concerned, to any aircraft, land or marine vehicle.
