Filed: 2022-05-17
Abstract: La présente invention se rapporte à un procédé d’oxydation des feuilles de métal à dorer par sérigraphie à l’aide d’une base incolore aqueuse associée à des acides.   Traditionnellement, l’oxydation de ces feuilles de métal à dorer est effectuée à la main avec des outils tels que des pinceaux de peintres en décor, des chiffons ou des éponges naturelles et des mélanges contenant des acides liquides. Cependant, ce travail à la main ne permet pas de créer des motifs extrêmement précis d’oxydation colorées et de les reproduire en série. Le procédé inventé permet de créer des images et nuances extrêmement précises et de les reproduire en série.  Le procédé consiste à mélanger une base incolore aqueuse composée de résine acrylique et des acides utilisés pour le traitement des métaux et de déposer cette solution sur des feuilles de métal à dorer à l’aide de la technique de la sérigraphie. Les feuilles de métal sont ainsi oxydées.   Le procédé selon l’invention est particulièrement destiné aux métiers en décoration, permettant à ceux-ci de proposer une gamme différente et plus précise de motifs et nuances oxydés.

Title: Semiconductor device - with reduced self-inversion
IPC: H01L21/18
Filed: 1972-01-31
Abstract: MIS devices in which an insulating layer is formed on a semiconductor wafer of first conductivity type and a second insulating layer is formed thereon, then a first masking layer. The exposed areas on the second insulating layer are etched away and the etch mask is removed. Those parts of the first insulating layer exposed by etching are themselves selectively etched, and a dopant is diffused into the substrate through the windows thus opened, to give the doped region a second type of conductivity. A third insulating layer is then applied to the exposed regions, or semiconducting layer is formed on top of the insulating layers and a fourth insulating layer is formed on the second semiconductive layer. Windows are exposed in the 4th insulating layer through which parts of the semiconductor layer are etched away, and a fifth insulating layer is applied to the semiconductor layer with windows, and a third masking layer is applied on the third, fourth and fifth insulating layers and the third and fourth insulating layers are etched away to remove certain diffused zones adjacent to the substrate and the adjacent parts of the second insulating layer. The regions thus exposed are coated with metal to provide leads. Process improves function losses and counteracts auto-inversion of the devices.

Title: Combustion gases homogenizing equipment - ensures uniform temperatures for drying plants, gas turbines and jet engines
IPC: F23R3/04
Filed: 1973-03-23
Abstract: Equipment to homogenise the mixt. of hot gases and colder dilution gases leaving a combustion chamber consists of a number of cold gas injection pipes in the periphery of the combustion chamber, extending nearly to the centre, spaced so that the gas mixt. can pass between them. The pipes have adjustable nozzles at their open ends orientated so that the velocity of issuing gas has a component opposed to the velocity of the hot gases. They are rectilinear and are arranged in the form of a truncated cone with its apex directed upstream. Alternatively they can be in the form of a hyperbola giving a rotating stream opposed to the hot gas flow. In the cases where the gases are so hot that pipes protruding into them cannot be used, the nozzles are placed in the thickness of the refractory walls. The area of use is in the construction of combustion chambers producing hot gases for drying or for feeding gas turbines or jet engines, in which cold air is fed in to give a desired gas outlet temp. The equipment brings about mixing of the cold air, fed in along the chamber wall to avoid the necessity of a refractory wall, and the hot gases in the centre of the chamber, by injecting a part of the cold air counter-current to the gas flow, eliminating differences in temp. between the peripheral gases and the gases in the centre.

Title: Air humidification and water cooling plant - allowing control over degree of satn of air leaving to atmos
IPC: F28F25/02
Filed: 1973-07-04
Abstract: A plant for contacting liqs. with gases, e.g. for humidifying air or cooling water, has several gas flow passages formed by vertical plates down which the water flows, and in addition, a system for distributing the water slow onto the tops of the plates so that it runs down (part of) the walls of the passages. The humidity of the air leaving the plant can be controlled according to the atmospheric conditions, so that condensation or even frosting, which might occur in mid-season or winter, can be avoided. In addn., the disadvantages of using heat exchangers such as deterioration of the exchanger and loss of air circulation pressure are avoided and the appts. is more efficient than systems using contact surface reduction or by-pass arrangements.
Patent FR-2238055-A1 (FR)
Title: I.C. engine pollution reduction system - injects variable proportion of exhaust gas into fresh air intake
IPC: F02M25/07
Filed: 1973-07-18
Abstract: A tube projecting into the exhaust pipe has its open end bent to face upstream so that it captures part of the exhaust gases. It is connected to a similar tube (8) projecting into the intake pipe (9) at a point which forms the throat of a venturi. This injection pipe can rotate and has a pulley (13) which is connected by cables to the accelerator so that it is turned in accordance with engine speed. At minimum throttle its open end (11) faces upstream and at maximum throttle it faces downstream. The amount of exhaust gas sucked in thus depends on the accelerator depression and therefore on engine speed.
Patent FR-2238043-A1 (FR)
Title: Two stroke internal combustion engine - has secondary piston attached by spring to main piston
IPC: F02B25/20
Filed: 1973-07-18
Abstract: The secondary piston (PS) is above the main piston (PP) and linked to it by a compression spring (R). On the power stroke the spring is compressed and the two pistons descend together. From the bottom dead centre the spring returns the secondary piston more quickly than the main piston and the space between them uncovers the admission port (Ad) through which a fresh charge is drawn in. As the main piston moves up it compresses the charge and pushes it through the transfer passage (C) to the space above the secondary piston where combustion takes place. Exhaust is through a poppet valve (S) in the cylinder head.
