Date Nov. 17, 1988.A cryogenic process of simultaneous selective desulphurization and gasoline removal of a gaseous mixture consisting mainly of methane and likewise containing H2S and hydrocarbons with C2 and more. Said gaseous mixture (1), after having eventually undergone an operation of removal of benzol (25) and then cooling (2) producing condensates (4), is washed between 0 DEG  C. and -45 DEG C. by means of a solvent (5) selective of H2S to produce a current of methane (64) having a partial pressure in H2S below 65 Pa and a liquid phase (9a) rich in H2S and containing at least 80% molar of the hydrocarbons of C3 and more of the gaseous mixture (1). The liquid phase (9a) is subjected to a demethanization (29, 9) producing a demethanized rich solvent (11) and a gaseous phase rich in methane (10), the solvent (11) then is cooled between -25 DEG  and -80 DEG C. sufficiently to produce its dissociation in a lower liquid fraction (38) that contains the H2S and, in methane equivalent, less than 5% molar of hydrocarbons and an upper liquid fraction (37) formed of the hydrocarbons of C3 and more. Said fractions (37, 38)are separated and the fraction (38) undergoes a regeneration (46, 16, 20) to produce a current (24) of acid gas rich in H2S and containing the small amount cited above of hydrocarbons and a regenerated solvent (21).

Abstract: The device comprises a frame (1a) mounted via a suspension (4a) on an axle (2) common to a pair of wheels, and a braking element actuated by a brake pedal and capable of braking the rotation of at least one wheel. The brake pedal (12, 13) is mounted so as to be fixed in rotation on the axle (2). The suspension element (4a) is mounted in the vicinity of the wheel (3a) about a cam (11a) integral with the axle (2), and comprises a braking member (9a). The wheel (3a) comprises a drum brake (15a) integral with the wheel and capable of interacting, at its periphery, with the corresponding braking member (9a) when the axle (2) is driven in rotation in a first direction by acting on the brake pedal (12), thus causing the braking member (9a) to be brought nearer to and into contact with the periphery of the brake drum (15a). The same action is controlled simultaneously on the other wheel of the axle (2).

Title: Method of downloading of data to an mpeg receiver/decoder and mpeg receiver and decoder
Inventor: MERIC JEROEME
IPC: G06F21/10
Filed: 1997-04-25
Abstract: In a digital satellite television system in which a television receives its signal via a receiver/decoder, such as a set top box, interactive applications can be downloaded and run on the receiver/decoder. The application code is arranged as modules, and the downloading of modules is preceded by searching a directory module within a specified local address. The modules are signed and the directory module is signed and encrypted so that a single encryption applies to all of the modules making up the application. Multiple public encryption keys are stored in ROM in the receiver/decoder, so that applications can be created by different sources, without the sources needing to know each other's private encryption keys. A facility is provided to enable an encryption key to be temporarily stored in RAM in the receiver/decoder, so that a manufacturer of the receiver/decoder can check its functionality. A signature of the directory may be hidden at a variable position in a block of dummy data in the directory module. An application to be downloaded may be checked against an application validation bitmap stored in the receiver/decoder. <IMAGE>
