Abstract: The invention concerns a method of creating a data file and a data processing network arranged to carry out such method. 
     An embodiment of the invention provides a file security system for data files associated with a host data processing system. The host system includes a data security device 11 which contains a secure host master key 13 and is capable of performing a variety of cryptographic operations. At initialization time, the host system generates a series of secondary file keys for the associated storage media and protects them by enciphering the secondary file keys under a variant of the host master key. When a data file is to be created, a random number is generated and defined as an operational key enciphered under the secondary file key of a designated storage media. The host data security device, using the enciphered secondary file key of the designated storage media transforms the enciphered operational key under contro; of the host master key into a form which permits the operational key to be used for enciphering host data. The operational key enciphered under the secondary file key of the designated storage media, as header information. together with the host data enciphered under the operational key is written on the storage media as an enciphered data file. When the data file is recovered, the host data security device, using the enciphered secondary file key of the designated storage media, transforms the enciphered opera tional key header information under control of the host master key into a form which permits the operational key to be used for deciphering the enciphered data file to obtain the file data in clear form.

Abstract: A method and apparatus for determining the angular position of a point in rotational motion which includes a disk coupled to rotate with the rotating part. The disk includes a plurality of alternating teeth and spaces located about its periphery. At least one of the teeth has been removed to form an absolute or reference mark. A transducer is located adjacent to the disk to produce an electrical signal representative of the passage of teeth and spaces past the transducer. The electrical signal is processed to produce one or more output signals representative of the instantaneous angular position of the rotating part. Accurate results are produced even when large variations in instantaneous speed of the rotating part occur.

Abstract: L'electrophorese a deplacement est effectuee sur un gel (11) ayant la forme d'un tube le long duquel des substances sont separees dans le sens axial. La methode utilise un agarose ou un gel de polyacrylamide (11) forme sur et supporte par un tube interne (12) qui joue egalement le role de conduit pour un fluide de refroidissement. Des gels tres minces sont utilises pour obtenir un passage court de degagement de la chaleur par exemple jusqu'a 3 mm. Le gel est supporte sur un cote seulement et l'autre cote est en contact avec des electrolytes utilises dans le procede par exemple des electrolytes de conduite, de deplacement, et de finition. Pour eviter le sechage du gel, ce dernier est maintenu en contact avec un liquide inerte non miscible a l'eau et il n'est pas en contact avec l'electrolyte. La methode est particulierement importante pour la separation de molecules ampholytes telles que des proteines ou des peptides. Pour fournir une indication du degre de separation, des ampholytes fluorescentes sont utilisees comme substances de marquage en tres petites quantites.
