Title: Element d'alimentation de gyroscope à plusieurs lasers annulaires
IPC: H01S3/097
Filed: 1986-02-12
Granted: 1990-12-27
Abstract: Les éléments d'alimentation antérieurs pour les lasers de gyroscopes à lasers annulaires multiples étaient inefficaces en ce sens qu'il devaient avoir une capacité de puissance de sortie très supérieure à celle qui était nécessaire pour entretenir le fonctionnement du laser. Cette inefficacité est réduite dans une large mesure par cet élément d'alimentation qui comprend une source (30) d'énergie à courant continu pour appliquer une tension d'allumage à un premier terminal (40) et une tension d'entretien à un deuxième terminal (42), et un dispositif d'interface (50) associé à chaque laser (12, 13, 14) pour coupler le laser au premier et au deuxième terminaux. La tension d'allumage peut allumer chaque laser, et la tension d'entretien peut entretenir l'écoulement du courant dans chaque laser, après leur allumage. Chaque dispositif d'interface comprend une résistance (52, 53, 54) qui connecte le laser au premier terminal et une diode (55, 56, 57) pour connecter de telle façon le laser au deuxième terminal que la diode ne permette pas au courant de s'écouler entre le premier et le deuxième terminaux.

Title: Device for synchronizing the speeds of the driving wheels of a vehicle during acceleration
IPC: B60T8/48
Filed: 1988-02-06
Granted: 1990-09-26
Abstract: In a so-called starting aid for motor vehicles, synchronism in the rpm of the drive wheels during starting is provided by feeding a brake pressure derived from the rpm difference of the drive wheels into the wheel brake cylinder associated with the wheel having the higher rpm. To this end, one brake pressure controller having a control piston and a valve is installed in each brake line to the wheel brake cylinders of at least two wheel brakes. The control pistons are actuated in opposite directions via a final control element to which a control signal derived from the rpm difference is supplied. Upon displacement, whichever control piston is driven closes the valve and feeds brake pressure into the associated wheel brake cylinder. In order that the starting aid will have a high control speed and a small structural volume, the final control element is embodied as an electric control motor.
