Title: Regulateur de puissance pour systeme de carte de credit sans contact
IPC: H02M11/00
Filed: 1987-03-10
Granted: 1991-07-10
Abstract: Un dispositif de transfert de puissance permet le transfert régulé de puissance depuis un bloc électrique (100, 300) à une carte de données portative sans contact (200) sans qu'il soit nécessaire de prévoir des circuits de régulation sur la carte elle-même. Le bloc électrique comporte une bobine primaire (101) permettant le couplage magnétique de la puissance à une bobine secondaire (101) située sur la carte, lorsque la carte de données est mise en rapport étroit avec le bloc électrique. Le dispositif comporte un microprocesseur (310), un amplificateur de puissance (130) avec la bobine primaire (101), une source de tension variable (320) et un appareil pour mesurer le flux de courant dans la bobine primaire (120). Lorsque la carte de données portative n'est pas mise en rapport étroit avec le bloc électrique, le microprocesseur fait en sorte que la source de tension variable émette une séquence de tensions par paliers. Le flux de courant actif est mesuré à chaque palier et stocké dans la mémoire. La puissance fournie à la carte de données est calculée en fonction de la différence entre les courants actif et de repos, multipliés par la valeur de la source de tension variable. Les mesures séquentielles de courant actif continuent jusqu'à ce que la valeur calculée de la puissance fournie à la carte de crédit dépasse une puissance de seuil prédéterminée, moment auquel la carte de données reçoit une quantité de puissance précise et prédéterminée.

Title: Circuit comprising an input amplifier connected to an opto-electrical transducer
IPC: H03G1/00
Filed: 1988-10-11
Granted: 1993-03-03
Abstract: A circuit arrangement has a pre-amplifier that has its input connected to an opto-electric transducer and whose gain is controllable by a final control element formed by a field effect transistor. In order to achieve an especially great range of dynamics, the pre-amplifier contains the drain-source path of a field effect transistor that is connected in parallel to a resistor in a feedback branch. This field effect transistor is activated or inhibited by a regulator. In this way, the range of control of a controllable amplifier arrangement following the pre-amplifier is doubly utilized. The circuit arrangement can be advantageously used in optical transmission equipment of PCM technology.

Title: Device for producing fibres, particularly mineral fibres, from a melt
IPC: D01D5/08
Filed: 1989-02-17
Granted: 1992-09-30
Abstract: In a fiberising device according to the nozzle blasting principle, the blasting nozzle (6) is followed on the downstream side by a subsonic diffusor (11) which is constructed as a pulse diffusor whose flow cross-section shows abrupt widening to form individual steps (13, 14, 15). This makes it possible to employ an average aperture angle ( alpha ) which is significantly greater than in subsonic diffusors with continuous flow confinement without harmful detachment of the main flow. Furthermore, the vortices which form underneath the cut-back areas prevent direct contact of the filament constituents with the wall, and this, together with the pronounced flow expansion and hence reduction in mutual contact and penetration of filament constituents, results in an appreciably reduced bead content. The diameter distribution of the fibres is uniformised, since, as a result of the energy consumption by the vortices, the strongly edge-accentuated velocity distribution coming from the slot (8) is more rapidly uniformised. By systematically introducing further blasting medium in the area of the subsonic diffusor (11) it is possible to influence the flow systematically in order to meet all fibre quality requirements.

Abstract: This invention relates to a method using synthetic peptides as solid phase immunoadsorbents for the detection of antibodies to Human Immunodeficiency Virus (HIV) gp120, and, in particular, antibodies having HIV neutralizing capabilities. The amino acid sequences of the peptides correspond to segments of the external envelope protein gp120 of HIV. These peptides have been found to be highly immunogenic, and are reactive with antibodies in sera of patients with AIDS, ARC or HIV infected individuals. They can also be used to elicit the production of neutralizing antibodies to HIV. More specifically, the present invention is directed to the use of a synthetic peptide selected from the groups consisting of peptides containing twenty-eight and thirty-three amino acids in a prescribed sequence, their analogues and mixtures, corresponding to the HIV-gp120 external protein for the detection of antibodies to HIV-gp120. It is particularly useful for the dectection of antibodies having HIV neutralizing capabilities. The detection method includes an enzyme linked immunoassay and other forms of immunoassay procedures. The present invention also relates to a method for generating high titer antibodies to HIV gp120 protein in healthy mamals, including humans, by the use of the synthetic peptides, their analogues or mixtures in either a conjugated or a polymeric form as a key component in a synthetic vaccine for the prevention of AIDS.

Title: Learning control process for an internal combustion engine and device therefor
IPC: F02D41/24
Filed: 1989-03-04
Granted: 1992-06-17
Abstract: Learning control process with pilot control for an internal combustion engine and device therefor comprising an adaptation value memory with a predetermined number of reference positions which can be addressed by sets of values of operating address quantities. When, during operation of the internal combustion engine, a reference position area is left after stationary operation, a learning process is triggered which modifies the adaptation value of said reference position if a control means gives a setting quantity differing from a desired regulated quantity. The difference in setting quantity is not used fully but only in a reduced way to modify the former adaptation value. This is done by reducing means which have as main function groups a learning intensity table (26), a meter reading memory (27) and a meter difference table (28). The meter reading memory memorizes the number of past occurrences of learning cases for each reference position. Depending on the meter reading and on the individual value of the difference in setting quantity, the learning intensity table gives a learning intensity value. Then the meter reading is modified by "1" if the difference in setting quantity is minimal, as long as a maximum value has not been reached. If however the difference in setting quantity is important and the meter reading is close to the maximum value, the meter difference table gives a negative meter difference value, so that the meter reading for the corresponding reference position is lowered, which in turn leads to an increased learning value for the same reference position in the next learning stage. The meter difference table makes it possible to modify the learning progress in both directions, i.e. to more advanced or easier learning. Such a fine adjustment reduces the vibrational tendency of the controlled system.
