Abstract: Procédé de commande du temps d'excitation de systèmes électromagnétiques, en particulier de soupapes électromagnétiques dans des moteurs à combustion interne, dans lequel le courant d'excitation i = i (t), basé sur un courant de maintien élevé pour une durée spécifique, décroît non pas vers zéro ou vers une valeur négative, mais vers une valeur se trouvant dans la plage positive au-dessous du courant de maintien. En raison des valeurs caractéristiques du courant et/ou de la tension dans le circuit d'excitation, le début et la fin de l'ouverture du pointeau de la soupape peuvent être déterminés avec une précision particulière et ces informations peuvent être prises en considération afin d'influer de manière optimale sur les conditions de fonctionnement du moteur à combustion interne.

Abstract: The high performance exhaust system for an internal combustion engine improves the power output at all running conditions of the engine, in particular the performance of the engine at low and mid-range running. A valve means (17) is adjustably positioned contigous to the end of exhaust pipes (14) for restricting the transmission of exhaust gas pulses from an expansion chamber back to the exhaust ports of the engine. Means (26, 27) adjust the position of the valve means (17).

Abstract: A tailstock (20) for a turning machine (10) has a housing portion (40) adapted to be moved and clamped on the machine base (16), and the housing portion (40) supports a beam portion (29) which extends outwardly from the housing portion. The beam portion is non-symmetrical, and of generally rectangular cross-section wherein its neutral axis (28) is coincident with the centre axis. Thus, the non-symmetry of the centre support has a principle modes of compliance which are dissimilar and these modes, when added to the compliance of a cylindrical workpiece, tend to increase the dynamic stability of the tailstock end of the workpiece.

Abstract: The arc-detection device comprises an electrode (28) extending along one (16) of the bars of a set of bars (12) whilst being electrically connected to this bar by an electrical connection (32) consisting of a limiting resistor and an electroluminescent diode. An optical fibre (38) captures the light emitted by the electroluminescent diode and conveys this light signal to a unit for processing and controlling triggering (40) of a head switch (22) for supplying the set of bars (12). An incipient arc (42) on the set of bars (12) creates strong ionisation of the gases whose ionised particles are attracted by the polarised electrode (28) thereby generating a charge-collection current in the electrical connection (32). This charge-collection current, which indicates the presence of an arc (42), is signalled by the electroluminscent diode, the lighting-up of which brings about the opening of the head switch (22). <IMAGE>

Abstract: The invention relates to drive units for the motive movement of upwardly opening swing doors, such as, for example, garage doors. So that these drive units can be as little susceptible to faults as possible and nevertheless be small and lightweight, it is proposed to accommodate the limit switches (8) protectively within the drive housing consisting of the base plate (1) and cover (2). Since the output shaft (5) projects outwards through the base plate (1), where a pinion (7) for driving a chain (18), for example, is fastened to it, it is proposed to push a bush (12), especially consisting of plastic, fixedly in terms of rotation onto an outside diameter of the pinion (7), in such a way that the bush (12) projects back just inside the housing coaxially relative to the output shaft (5), this end of the bush (12) having a bevel gear (13). There meshes with this a bevel pinion (14) at the end of a threaded rod (9) on which are located nuts (10) which are prevented from corotating with the threaded rod (9) by an angle piece (16) bearing in parallel against them and which consequently move axially along the threaded rod (9) in a similar way to the movement of the door. Because the limit switches (8) are arranged parallel to the threaded rod (9), these nuts (10) of variable basic position as a result of the removal of the angle piece (16) are used for actuating the limit switches (8). <IMAGE>
