Title: Procede et dispositif de commande de soupapes de securite
IPC: F16K31/06
Filed: 1987-10-01
Granted: 1993-07-28
Abstract: Selon un procédé de commande de soupapes de sécurité, le corps de fermeture de la soupape est comprimé sur le siège de soupape, contre la pression du milieu à enfermer, par un cylindre de réglage relié à un circuit hydraulique de commande. Lorsque la pression d'actionnement est atteinte, des soupapes magnétiques à réaction rapide s'ouvrent, évacuant le fluide hydraulique du cylindre de réglage et déclenchant la course d'ouverture de la soupape. Lorsque la pression d'actionnement tombe au-dessous d'un certain niveau, les soupapes magnétiques d'évacuation se ferment et du fluide hydraulique est fourni à nouveau au cylindre de réglage par des soupapes magnétiques d'alimentation. Afin de régler la course de la soupape, des lignes caractéristiques de pression et de vitesse de changement de la pression sont calculées et enregistrées électroniquement. La pression du fluide des cycles de courte durée est également mesurée et enregistrée. La longueur du pas de course pendant chaque cycle est déterminée après le calcul de la vitesse de changement de la pression. L'ordinateur calcule alors la quantité de fluide hydraulique à évacuer ou à fournir pendant chaque cycle et les impulsions d'ouverture des soupapes magnétiques pendant chaque cycle en sont déduites, de sorte que l'ouverture et la fermeture de la soupape de sécurité sont réglées selon la ligne caractéristique, en petits pas à des vitesses réduites de changement de pression et en grands pas ou selon un pas d'ensemble à des vitesses élevées de changement de pression.

Granted: 1991-01-30
Abstract: A hood top (1) for a motor vehicle comprises an outer panel (2), an inner panel (13) secured to the outer panel (2), and a striker (20) for a latch mechanism (30) secured to the inner panel (13) towards the front of the hood top by welded joints (14,25). The striker (20) and the part of the inner panel (13) to which it is secured are so disposed relative to the outer panel (2) that when the hood top (1) is closed a substantial proportion of the reaction to the closing forces on the hood top (1) is transmitted to the welded joints (14,15) as shear forces. Since welded joints are capable of withstanding greater shear forces than compressive or tensile forces, the required durability of the connection between the striker (20) and the inner panel (13) can be achieved without the necessity for additional reinforcements or complex shaping of the inner panel (13).
Patent EP-0299929-B1 (EP)
IPC: F16C7/04
Filed: 1988-06-21
Granted: 1991-11-13
Abstract: The device comprises two rods (11, 12) which are each intended to be connected to one of the structural elements (3, 5) and at least one helical spring (15) whose ends are connected to two discs (13, 14), each associated with one of the rods (11, 12), so as to oppose the movement apart of the rods (11, 12) through the discs (13, 14). The latter are mounted for axial sliding relative to the associated discs (13. 14) and are formed in such a way that their movement both towards and away from each other causes tensioning of the spring (15) from its undeformed rest condition. The device acts as a rigid connecting element when the stresses applied to it are less than a predetermined threshold. When the stress exceeds the threshold, however, it deforms resiliently to limit the amount of stress transmitted to the members (3, 5) between which it is connected.

Title: Magnetic chuck for clamping or lifting work pieces
IPC: B23Q3/154
Filed: 1989-07-05
Granted: 1992-07-01
Abstract: The magnetic chuck for chucking or raising workpieces has differently poled (S and N) magnetic pole pieces (1), between which is located a pole pitch (2) of non-ferromagnetic material. In order to make the magnetic chuck more universally usable for workpieces made from non-magnetizable or weakly magnetizable material, it is additionally constructed as a vacuum chuck. This is brought about by correspondingly differently designed bores or slots, which are preferably filled with sintered metal and by means of which the vacuum is applied through corresponding vacuum lines. Due to the fact that the magnetic force and/or the force applied by the vacuum is available as a retaining or holding force, a universal use of the same tool is possible and simultaneously a considerable holding force can be applied.
