Inventor: BENET JEAN
IPC: B60T8/18
Filed: 1989-07-18
Abstract: Proportioning device for a brake system of automotive vehicles, comprising two independent circuits having two control slide valves (5 and 6) making it possible to supply fluid under pressure to each circuit, the first slide valve (5) being sensitive to a device (8) actuated by the driver for controlling the fluid pressure admitted into a first circuit from a first source of fluid under pressure (1a), for example a hydropneumatic accumulator, the second slide valve (6) being subjected at one of its ends to the fluid pressure of the first circuit and at its other end to the fluid pressure of the second circuit, this second slide valve (6) controlling the pressure of the second circuit from a second source of fluid under pressure (1b), for example a hydropneumatic accumulator. Each of the circuits respectively feeds the cylinders of a front wheel and a rear wheel, for example diagonally opposite one another, and each of the control slide valves (5 and 6) delivers via a first conduit (10 or 21) a front braking working pressure (UIAV and UIIAV) and via a second conduit (11 or 22), arranged in the same plane as the first conduit (10 or 21), a rear braking working pressure (UIAR and UIIAR). Means CI and CII for correcting the rear braking pressure as a function of the vehicle load are provided inside the proportioning device and are fed with fluid under pressure via the said second conduits (11 or 22). <IMAGE>

Abstract: A shaft synchronous balancing apparatus wherein a rotor to be balanced is rotated in conjunction with appropriate balance plane located transducers and a non-contacting shaft monitoring pick-up, for example of an optical variety. The latter pick-up derives a one times per revolution reference signal which is treated by a software driven process control system including dual timer-counters to evaluate the period of revolution, T, and to develop N incremental sampling pulses having a duration or time constant of T/N. Preferably, N is an even integer power of 2. Periodic updating of the duration of a time constant is developed utilizing only one software interrupt in conjunction with the two counter timers. A nulling technique for canceling offset at the signal treatment stages is provided which accommodates for the high amplification levels necessary at the front end of the system. Additionally, a gain adjust feature achieves optimum precision and reliability for the system by performing within three discrete ranges.

Title: Multi-edge detection valve
Inventor: HUBER REINHOLD
IPC: F16K3/34
Filed: 1989-05-23
Abstract: Two coaxial control bushes (18) are inserted in a cylindrical bore (6) of the housing (1) of the detection valve and are braced relative to one another by means of a spring (19). One bush bears against a stop (7) fixed to the housing. The other is axially displaceable by means of an adjusting screw (20). A control slide (40) is axially displaceable in each of the coaxial control bores (23) of the two bushes (18). The control bores (23) have circumferential grooves (24, 25) forming a first set of control edges (32, 33). The groove (24) is connected to a delivery connection (2) and the groove (25) to a return connection (3). A recess (45) of each of the control slides (40) forms a second set of control edges (49, 50). The two recesses (45) each communicate with an outlet connection (4, 5). The mutual displaceability of the bushes (18) simplifies the production of the detection valve. The two control edges (49, 50) are assigned to two auxiliary control edges (59, 60). These are connected to the respective outlet connections (4, 5) via a shutter (64). Thus, in the region of the neutral position, a high pressure intensification and a low throughflow intensification are obtained, so that, in pneumatic uses, the detection valve allows a high static rigidity and at the same time a stable dynamic operation. <IMAGE>

Abstract: The invention relates to a door lock, especially for vehicle doors, in which a preferably bolt-shaped locking device (10) on the door leaf (21) interacts with a latch (10) mounted pivotably on the door frame (1). The latch has a groove (19) receiving the locking device and is under the effect of a spring, the tension of which increases as a result of the pivoting movement of the latch occurring during the closing of the door. The latch is pivotable by means of a pneumatic tumbler cylinder and has at least one notch (22,23), into which a detent pawl (24) releasable by means of a pneumatic blocking cylinder engages in the end region of the door-closing movement. According to the invention, the locking device (20) arranged in the door leaf (21) and the pivot axle (8) in the latch (10) are directed essentially parallel both to the door leaf (21) and to the door-frame part (1) carrying the latch (10). <IMAGE>

Abstract: Un récepteur de recherche de personne (10) est compatible avec des transmissions provenant d'émetteurs de recherche de personne analogiques ou numériques. Le récepteur de recherche possède une structure de commande qui lui permet d'être programmable dynamiquement pour changer sa fonctionnalité, y compris la programmation de fréquences de canaux que le récepteur de recherche va recevoir. La programmabilité des fréquences de canaux permet au récepteur de recherche de personne d'être utilisé pour effectuer des recherches de personne sur un plan national, régional, local, une zone éloignée, et pour envoyer des avis de recherche à un groupe dans une région locale ainsi que pour effectuer une commutation des fréquences de canaux qui sont utilisés intensivement pendant les périodes de pointe pour passer à des canaux moins utilisés. Le récepteur de recherche de personne transmet les chiffres d'un code d'identification du récepteur dans un ordre d'importance croissante ce qui réduit de manière considérable la consommation d'énergie de tous les récepteurs syntonisés sur une fréquence particulière pour déterminer si un avis de recherche doit être reçu, ce qui permet de prolonger la vie des piles du récepteur. Le récepteur affiche le lieu d'origine des messages de recherche, soit comme une origine locale soit d'autres origines. L'antenne (12) du récepteur est syntonisable en continu pour permettre la compensation des variations du gain de l'antenne dues aux facteurs de l'environnement qui peuvent dégrader sérieusement la force du signal.

Abstract: In a gaming machine with win output, one of a plurality of visible symbol representations can be triggered according to a random function by means of a game-initiating unit (5) actuable as a function of the insertion of money or the like. Predetermined symbol representations, namely the win-symbol representations, are each assigned a predetermined win. When a win-symbol representation detector (11) detects a win-symbol representation, a digital win representation assigned to it by a win allocator (15) and, as a function of this, the output of the win assigned to it can be triggered in a win output unit (19). To persuade a player to play more often, the gaming machine contains a device (17, 20-39) which selectably blocks the win output and which increases the win possibility with an increasing number of wins stored intermediately during a blockage of the win output. <IMAGE>
