Title: Automatic power cut-off device for emergency situations
Inventor: BAE MYUNG SOON
IPC: H01H51/01
Filed: 1999-02-23
Granted: 2003-04-29
Abstract: An automatic power cut-off device for emergency situations which is capable of immediately sensing occurrence of an emergency situation such as an accident of a vehicle striking against an obstacle during its running at a high speed, and automatically cutting off electric power flowing through the vehicle, thereby protecting a driver or other passengers in the vehicle from fire or explosion. The automatic power cut-off device includes an impact sensing device having an impact sensor adapted to sense an impact, thereby generating an impact sensing signal, and a solenoid driving circuit for activating a solenoid in response to the impact sensing signal. A return knob is also provided which rotates between a first position, in which connecting terminals respectively coupled to an electric power source and a load are electrically connected to each other, and a second position, in which the connecting terminals are disconnected from each other. The return knob is maintained in its first position in an inactive state of the solenoid as it is engaged with an engagement extension provided at the solenoid. When the solenoid is activated, the return knob is disengaged from the engagement extension, so that it rotates to its second position by a tension coil spring. Thus, the supply of electric power is cut off.

Granted: 2008-05-20
Abstract: Improved settlement of solids is provided, while minimizing problems in collecting clarified liquid from a clarifier, by controlling the flow of clarified liquid from a given one of many flow channels of a clarifier. Such control is by causing a substantial amount of that flow of clarified liquid to be collected immediately as that flow exits the given flow channel. Such collection of the substantial amount, if not all of that flow of the clarified liquid from the given flow channel, minimizes if not eliminates, the mixing of the flow from all of the flow channels of a clairfier. As a result, during normal settling operations the flow of the clarified liquid from the given flow charmel is substantially isolated. During such normal operations, the isolated flow may be separately sampled for examination of the performance of the separate flow channel. If too many solids are present in the clarified liquid from that separate flow channel then one or both of the plates that define that separate flow channel may be removed and replaced. Servicing operations of removal and replacement of the one or both plates are performed without interrupting the normal settling operations of the other flow channels.

Abstract: Ce système de dessin assisté par ordinateur (DAO) permet à un dessinateur d'entrer facilement des entités de cote décrivant les cotes physiques d'un objet dans un dessin ou un modèle assisté par ordinateur. Les entités de cote définissent des cotes linéaires, angulaires ou radiales et, pour chaque entité, l'utilisateur définit une origine de référence en sus de l'information de cote normale. La valeur de chaque entité définie peut être une constante simple, un paramètre ou une expression de plusieurs constantes et paramètres. Du fait de l'ajout de l'origine de référence, un réseau très complexe d'entités de cotes connexes peut être simplement défini et facilement modifié. Il est procédé à un nouveau calcul des entités de cote au moyen d'un moteur de cotation paramétrique transformant des groupes d'entités provenant de l'espace global du dessin ou modèle DAO général en espace local. Etant dans cet espace local, le moteur de cotation paramétrique calcule à nouveau les données de coordonnées des entités.

Abstract: A material is exposed to a neutron flux by distributing it in a neutron- diffusing medium surrounding a neutron source. The diffusing medium is transparent to neutrons and so arranged that neutron scattering substantially enhances the neutron flux to which the material is exposed. Such enhanced neutron exposure may be used to produce useful rad io- isotopes, in particular for medical applications, from the transmutation of readily-available isotopes included in the exposed material. It may also be used to efficiently transmute long-lived radioactive wastes, such as those recovered from spent nuclear fuel. The use of heavy elements, such as lead and/or bismuth, as the diffusing medium is particularly of interest, since it results in a slowly decreasing scan through the neutron energy spectrum, thereby permitting very efficient resonant neutron captures in the exposed material.

Abstract: A process for removing or stabilizing arsenic and/or selenium from aqueous streams or slurries is provided that includes contacting the streams or slurry with a composition containing lanthanum chloride. The lanthalum chloride composition can optionally contain various lanthanides. The composition can optionally contain ferric or ferrous sulfate.  The process is preferably conducted by adjusting the pH of solution to between about 8 or 10, adding 2 moles of lanthanum chloride for every mole of arsenic or selenium ions present in solution, adding 5 to 6 moles ferric or ferrous ions for every mole of arsenic or selenium ions present in solution and adjusting the oxidation potential of the solution to between 200-400 mV for removal of selenium ions and between 100-200 mV for removal of arsenic ions. Using the processes of this invention, the selenium and arsenic concentrations can be reduced to less than currently acceptable limits and arsenic and selenium can be stabilized from leaching, decomposition or other degradation processes.
