Inventor: MORTELETTE ANDRE
IPC: B64G1/40
Filed: 1981-08-27
Abstract: 1. A method of changing the orbit of a space vehicle allowing among others a transition from a highly elliptic orbit (2) to a circular orbit (4) possibly geosynchronous and of different inclination, according to which the vehicle is made to follow a plurality of successive intermediate orbits (4A-4N) by means of speed increments in directions approximatively tangent to the orbits, resulting from accelerations compatible with the mechanical behaviour of the vehicle in operational configuration, such accelerations being modulated so as to ensure the desired direction to the resultant, said method being characterized in that it consists of : - aiming with a launcher at a transfer orbit (2) the apogee (3A) of which is close to the desired value for the final orbit (4), - making the vehicle change from such transfer orbit (2) to the final orbit (4) through successive intermediate orbits (4A, 4B ... 4N) the apogees of which are adjoining but the perigees of which get closer to the desired final value, by means of a succession of speed increments delivered in the immediate neighbourhood of the successive apogees resulting from accelerations obtained by means of motors (12) intended for subsequent orbit and attitude control during the operational life of the vehicle, and - modulating such accelerations depending on information provided by speed or angular position sensors, also usable in the other flight phases of the vehicle.

Abstract: In watches to be worn on the body, the support member such as a wrist strap or neck band often is secured to the watch by means of a connecting member at a distance from the periphery of the watch casing. Generally tongue portions are formed on the watch casing and the connecting members fitted thereto and secured against movement in a direction opposite to the fitting direction by complex means such as screw and springs. In the improved watch casing of the invention, tongue portions (1a) are formed on the casing shell (1). The connecting members (4) which can be fitted from above engage into recesses in the tongue portions and are thereby secured in position transversely with respect to the direction of fitting. The ends of the tongue portions extend over fixing axis members (6) which are fitted after positioning of the connecting members (4) between the members 4 and 6 so that the fixing axis members (6), and the loop portions (5a) of the wrist strap or bracelet which pass therearound, automatically secure the connecting members (4) in position in a direction opposite to the fitting direction.

Abstract: Des cellules animales sont immobilisees par adsorption de cellules animales dependant de l'ancrage sur des micro-porteurs qui peuvent etre degrades enzymatiquement avec des enzymes tels que la dispase et la collagenase pour liberer les cellules intactes. Les micro-porteurs comprennent des proteines et des polysaccharides naturels ou leurs derives, tels que la gelatine et le chitosane. Les micro-porteurs peuvent etre modifies avec un agent de reticulation tel que le glutaraldehyde pour donner une plus grande resistance aux temperatures elevees et une meilleure resistance mecanique. L'incorporation de particules d'un materiau magnetique tel que Fe3O4 dans les micro-porteurs permet l'utilisation d'un champ magnetique exterieur pour agiter, suspendre et/ou isoler les micro-porteurs. Dans un autre mode de realisation, des cellules animales sont immobilisees en emprisonnant des gels d'alginate ou d'agarose.

Abstract: This invention relates to a process for producing polyalkenyl succinic anhydrides by reacting with continuous agitation a polyalkylene having a number average molecular weight of between 300 and 50,000 with maleic anhydride in a molar ratio of between 0.5:1 and 20:1 and at a temperature between 200 and 250°C. The feature of the process is that the maleic anhydride is added incrementally to the polybutene at such a rate that a single, homogeneous phase is maintained in the reactor throughout the duration of the reaction and the addition of maleic anhydride reactant is completed within 75% of the duration required to achieve maximum conversion of the polyalkylene of a given molecular weight. The polyalkylene derivative may for example be a polypropylene, a polybutene, a polyiso-butene or polymer of 4-mathyl pentene-1. By carrying out the reaction under these condi- tions the process results in a reduced amount of resin formed and enables more efficient use of maleic anhydride..

Abstract: Waste sulfuric acid streams, varying in content and concentration, are dispersed with controlled quantities of oxygen and efficiently decomposed to yield sulfur dioxide. After passage through a control metering devices the oxygen containing gas is introduced into an acid spray mixer-nozzle. In the nozzle the oxygen containing gas flows through an annular space in the nozzle at a positive pressure and escapes through a plurality of holes (53 and 54) peripherally formed at the tip of the nozzle. Concurrently the waste sulfuric acid flows under pressure interiorly of the peripherally formed holes of the spray nozzle. As the acid leaves the nozzle it is struck by converging jets of the oxygen containing gas as the gas flows through the gas jet holes (53 and 54) at the tip of the nozzle. The collision of the waste acid stream with the jets of oxygen containing gas is effected outside and downstream of the tip of the nozzle. The converging gas jet streams surrounding the liquid waste acid stream causes the stream of acid to shear and form into small droplets. The size of the droplets is controlled by the pressure and volume of the oxygen containing gas introduced to the spray nozzle.
