Patent number: 4202346Abstract: This catheter comprises at least one tube and preferably two tubes. These tubes are, at one of their ends, parallel and open out into an inflatable balloon and are, at their opposite ends, independent and extend through an end member and terminate beyond the end member in a flared end portion. The latter is clamped in a sealed manner between the end member and a cylindrical socket. The latter is adaptable in a receiving head of an apparatus which is integral with a syringe or other source of fluid so that the tube is thus supplied with safety with fluid such as a contrasting product, a product which is opaque to X-rays or a silicone for obturating the vessel for the purpose of inflation or delfation of the balloon, for the control of its position and possibly for the definitive obturation of the vessel. This catheter and the apparatus are also particularly adaptable for neuroradiological examinations and to treatments of blood vessels.Type: GrantFiled: August 8, 1977Date of Patent: May 13, 1980Assignee: Societe d'Etudes et d'Applications Technologiques-SeratInventor: Pierre M.

Patent number: 4201981Abstract: A display instrument for aircraft wherein a representation of a data value is recorded and indicated by the position of an illuminated bar alongside a graduated scale. A number of bars are located along the scale, each bar being formed by the emitting end of a respective bundle of optical fibres. A particular bundle is illuminated to illuminate its bar according to a digital value stored in a counting register. This value is variable by the manual rotation of a knob driving an apertured disc so that each time a light beam passes through an aperture as the disc rotates, the beam is incident on an opto-electronic receiver, thus, providing a signal which changes the value stored in the counting register.Type: GrantFiled: May 11, 1978Date of Patent: May 6, 1980Assignee: Societe Francais d'Equipements pour la Navigation AerienneInventor: Jean L. Grissonnanche

Patent number: 4199295Abstract: A device for reducing the noise generated by the blades of at least one r of rotor blades in a turbo-machine by the production of a counter-noise of opposed phase. This is achieved by injection of jets of fluid under pressure through orifices borne by the rotor located near to the periphery of the blades, and the flow of the fluid is modulated at a frequency which is a whole number multiple of the rotational frequency of the rotor shaft. Regulation of phase of the modulated injected fluid is carried out in such a manner that the acoustic waves generated by the injected fluid are substantially in opposition, with respect to phase, to those of the noise to be reduced.Type: GrantFiled: November 7, 1977Date of Patent: April 22, 1980Assignee: Societe Nationale d'Etude et de Construction de Moteurs d'AviationInventors: Pierre M.

Patent number: 4198828Abstract: A device for supplying coolant to a cryostat has a container containing liquified gas. An insulated first tube supplies coolant gas from the container to the cryostat. An end part of this tube is located inside the container and is bent into a U-shape so that the bend is immersed in the liquified gas, but the mouth of the tube at the free end thereof inside the container, opens above the level of the liquified gas so that the coolant gas can enter the first tube. After leaving the cryostat, the coolant is conveyed to a suction inlet of a pump which propels the coolant along a second tube which opens into the container below the liquid level. A heat exchanger to give a cooling effect is disposed adjacent this U-bend.Type: GrantFiled: May 18, 1978Date of Patent: April 22, 1980Assignee: Societe d'Etudes d'Automatisation, de Regulation et d'Appareils de Mesures S.A.Inventors: Jacques Mercier, Andre Ponthus
