Abstract: An electric current-limiting circuit breaker comprises a pair of separable contacts and a selective solid state trip unit including an actuator cooperating with a latch mechanism for actuating the contacts to a positive open position upon occurrence of an overcurrent condition. The movable contact may also be moved by electrodynamic repulsion towards the open position when the fault current exceeds a predetermined threshold to effect current limiting. A tripping control device has an electronic counter which counts successive opening and closing cycles of the contacts so as to trip mechanism after a given number of cycles. The trip unit further comprises a first time delay tripping circuit, and a second instantaneous tripping circuit which cooperates with the cycle counter so as to ensure either instantaneous tripping or tripping by counting up to a number of cycles preselected on a setting selector.

Abstract: On a découvert des classes d'accélérateurs plastifiants tensio-actifs cathioniques (SAPA) à utilisation multiple qui servent d'agents de traitement interne à la fourchette de température inférieure conventionnelle de traitement du caoutchouc allant de 30 à 100oC, puis qui se dissocient à la température plus élevée utilisée pour la vulcanisation (>140oC) pour former une amine secondaire servant d'accélérateur organique de la vulcanisation. L'efficacité de la dispersion de la charge est accrue par la présence de l'agent tensio-actif et les produits vulcanisés ont souvent une résistance supérieure à la normale. Il n'est pas nécessaire d'inclure de l'oxyde de zinc et de l'acide stéarique dans la composition pour obtenir une vitesse de vulcanisation élevée et d'excellente propriété physique; toutefois, l'inclusion d'une certaine quantité d'oxyde de zinc est utile si un anti-grillage est préférable et si l'on a besoin de produit vulcanisé possédant une résistance maximale au vieillissement dû à la chaleur. Les SAPA peuvent être utilisés comme accélérateurs de vulcanisation en tant que tels ou en combinaison avec des accélérateurs conventionnels pour le caoutchouc. Les classes particulières utilisées de SAPA sont les sels d'acide gras de diamine d'alkyle alcène et d'imidazoline d'alcoyle. Les SAPA peuvent également comporter un alkyle bisalkylamide ou un sel d'acide gras d'une diamine d'alkyle alkane. Il n'est d'habitude pas nécessaire d'utiliser des agents de démoulage puisque les produits vulcanisés par SAPA se démoulent d'eux-même en raison de la libération in situ d'un composant d'acide gras pendant la vulcanisation.

Title: Method of and installation for producing castings from pressure treated melts from steel alloys
IPC: C21C7/00
Filed: 1987-10-10
Granted: 1991-12-27
Abstract: A method of producing castings, such as blocks, billets or dead-mould castings from metals, in particular steel and steel-like alloys, which have higher proportions of elements with high vapour pressure or gases than at atmospheric pressure in the molten state and remain in solution during solidification is to be improved by virtue of the fact that a melt produced in an open melting unit is poured first of all under atmospheric pressure into a refractory-lined, heatable treatment vessel, a gas pressure above atmospheric pressure is then built up over the melt and is maintained during the entire heating and treatment time, the melt is continuously stirred and/or flushed by means of gas and, either by flushing with the elements or substances in the gaseous state and/or by the addition of alloys containing the element or substance, is brought to the desired content of this element or substance, the gas pressure above the melt corresponding at least to the partial pressure of the corresponding element or substance, which partial pressure is in equilibrium with the desired content of the melt, and that the melt, after the composition and the casting temperature are set, is poured directly from the treatment vessel via a closure and casting element which can be closed and opened in a suitable manner into an ingot mould, likewise under pressure, a ceramic or metallic casting mould or a continuous-casting ingot mould, or that the melt is pushed directly into a casting mould according to the die casting method by increasing the pressure above the melt, and the casting thus formed is left to solidify.

Abstract: An internal combustion engine may be driven in the suction mode as well as the supercharging mode. Switchover from the suction to the supercharging mode takes place with the accelerator pedal in a switchover position, and switchback to the suction mode is effected in the return switching position of the accelerator pedal. The switchover and switchback positions are offset with respect to each other with the accelerator pedal in a central position between its initial position and its final position. The arrangement is such that the switchover position is reached at the end of the suction mode at fully open throttle flap (full power position). Upon switchover the throttling of the supercharging flow (throttling begin position) is increased as compared to the end of the suction mode. This throttling of the supercharging is diminished by further actuation of the accelerator pedal in the direction of the final position. Corresponding switchback from the supercharging to the suction mode takes place when the accelerator pedal is in the switchback position at which the drive of the supercharger established by the engine shaft is interrupted and a change is made from the stronger throttling during the supercharging mode to the weaker throttling in the suction mode.
