Abstract: When transferring data, an electronic document or the like from a first computer system (100) to a second computer system (200) via a data transmission line (300), e.g. a public data transmission line, a first output and input station (122) comprising a first electronic card (124) and a second output and input station (222) comprising a second electronic card (224) are used. 
     The data is transferred to the first electronic card (124) from the first computer system (100) via the first station (122) and is en­crypted in the first electronic card (124), whereupon the data is output from the first electronic card (124) in encrypted form and transferred via the first station (122) to the first computer system (100) and therefrom to the data transmission line (300). 
     The data is received by the other computer system (200) in encrypted form and is transferred to the second electronic card (224) via the second station (222), whereupon the data is decrypted in the second electronic card (224) and is output from the second electronic card via the second station (222) to the second computer system (200). As the data transfer between the first and the second computer system is carried out between the first and the second electronic card, no third parties have neither authorized nor unauthorized possibility of interfering with the data transmission and possibly changing the data or the electronic document. The first and the second electronic card (124, 224) constitute a coherent set of cards comprising coherent encryption/decryption keys input into the internal storages of the cards.

Abstract: An integrated optical semiconductor device having improved optical coupling efficiency between optical semiconductor devices. An optical waveguide layer (3) is provided on a semiconductor substrate (1). On the waveguide layer, a first active layer (103) and a second active layer (104) having nearly the same thickness are provided, and they are directly coupled together along the end surface (107) to constitute a first optical semiconductor device (105) and a second optical semiconductor device (106). In the step of manufacture, an etching stop layer is interposed in advance between the optical waveguide layer (3) and the first active layer (103). Owing to this constitution, the two active layers are formed maintaining nearly an equal height without permitting the optical waveguide layer (3) to be etched. Therefore, there is obtained an integrated optical semiconductor device having good optical coupling efficiency.

Abstract: Procédé pour fabriquer des mélanges tensio-actifs dont des alkyléthersulfonates, ou leurs sels (éthersulfonates), sont le constituant principal et qui sont utiles en particulier dans le cadre de l'exploitation tertiaire du pétrole, en faisant réagir des alkyléthersulfates avec une solution aqueuse de sulfite alcalin à une température comprise entre 160 et 220°C. Pour obtenir des mélanges des éthersulfonates au moins en grande partie exempts de sels de sulfate à partir d'alcools alcoxylés d'origine naturelle et/ou synthétique, la réaction se fait avec des quantités au plus à peu près égales des alcools alcoxylés, dans un milieu aqueux, à un pH légèrement alcalin, avec un excédent stoechiométrique de sulfate alcalin; suit, le cas échéant, une réaction ultérieure dans les conditions précitées; on extrait ensuite le mélange tensio-actif ainsi obtenu avec des alcools au moins en grande partie solubles dans l'eau, à une température inférieure mais toujours élevée. L'invention porte en outre sur l'utilisation pour l'extraction tertiaire du pétrole de ces mélanges tensio-actifs, en particulier sous forme de mélanges avec de l'alcool résiduaire provenant de la phase d'extraction.

Abstract: PCT No. PCT/GB90/01698 Sec. 371 Date May 7, 1992 Sec. 102(e) Date May 7, 1992 PCT Filed Nov. 6, 1990 PCT Pub. No. WO91/06440 PCT Pub. Date May 16, 1991.In an air suspension system of a vehicle the height of the vehicle platform is maintained in use by height control valves. To facilitate loading, the height may be adjusted by an operator by overriding the height control valves by means of a selector valve. The height may then be adjusted by a Raise/Lower valve. If the operator omits to return the selector valve and/or the Raise/Lower valve to their normal condition, the selector valve is reverted to its normal condition by a pilot line connected to a service brake line so that the vehicle automatically returns to its normal ride height on the first brake application. Alternatively the valve may be operated by a solenoid connected to the brake light circuit so that the service brake line is not affected. In an alternative arrangement, the suspension system height is adjusted by two manually-operable spring-return valves. Again, a selector valve reverts to a condition in which ride height is attained on application of the service brake.

Abstract: The invention relates to a hydraulic control device for the load-independent flow control and unpressurised discharge of a flow of working medium delivered by a pump (26) to the tank (25). In this device, a balance piston (2) can be moved in a cylinder space and divides the cylinder space into a pump pressure space (5) and a load pressure space (8). The pump pressure space (5) is connected to the pump line (3) and the load pressure space is connected to at least one consumer line (9). The balance piston (2), which is supported against the pump pressure by a force transmitter on the load pressure side (8), frees the control edge (6) in the case of a movement counter to the force transmitter. Via this edge, the flow of working medium can be connected completely or partially to the tank flow outlet (7). The invention consists in the fact that the force transmitter is a hydraulic piston (13), a piston rod (10) of which passes through the load pressure space and acts directly on the balance piston (2). On its side facing the load pressure space (8), the piston (13) is pressure-relieved and, on the side facing away from the load pressure space (8), i.e. from the direction of the cylinder space (16), is subjected to an adjustable hydraulic pressure. <IMAGE>
