Abstract: One or more apparatuses are provided for forming a seal between a circuit breaker and an enclosure. A adjustable door assembly comprises an inner floating frame assembly positioned according to a floating configuration between a first external flange and a second external flange that connect to an enclosure door of an enclosure housing a circuit breaker. The inner floating frame assembly comprises an inner floating frame and an inner floating box frame. An adjustable coupling is used to apply a force, between the inner floating frame and the inner floating frame box, to the inner floating box frame towards a front side of the circuit breaker to form a seal between the front side of the circuit breaker and the enclosure door. The seal may provide a barrier for mitigating arc flash, hazardous gases, material, and/or explosive force from escaping from a backside of the circuit breaker.

Abstract: A method is provided for analyzing and diagnosing a large scale process automation control system having a plurality of control loops. Assessments for predefined key performance indicators (KPIs) are automatically generated for control, process and signal sections of each control loop. The automatically generated assessments of the pre-defined KPIs may be displayed in a graphical user interface (GUI) of a computer. A user may change the automatically generated assessments of the pre-defined KPIs. Different data views may also be displayed in the GUI. The data views include time series trends for measured process variable, controller output, controller set point and error, as well as controller parameter clustering views in two-dimensional and three-dimensional plots.

Abstract: A method and system operates a well having an outer casing, a tubing positioned inside the outer casing, and a plunger moveable within the tubing to periodically draw out a liquid slug. A chemical to slug size ratio is set by the operator. Thereafter, the gas flow rate is monitored and the well is shut-in when the gas flow rate drops below a predetermined threshold. After well shut-in, a calculated amount of chemical foaming agent is injected. The size of the liquid slug is calculated and then the well is opened, drawing the plunger and liquid slug up to the surface. The calculated amount of chemical foaming agent is calculated based on one or more previous liquid slug size determinations and the set chemical to slug size ratio.

Abstract: Systems and methods for identifying faulted segment(s) in a multiphase power network may include receiving a current measurement that was measured during a fault, obtaining a set of equivalent sequence impedances for the segments, building a set of sequence bus impedance matrices, selecting a segment, calculating coefficients for the segment based on the set of equivalent sequence impedances for the segment and the sequence bus impedance matrices, calculating an estimated per unit fault distance for the segment based at least partially on the current measurement and the coefficients, identifying the segment as a potentially faulted segment if the estimated fault distance for the segment is between about zero and about one, and repeating for each of the segments the calculating coefficients, calculating an estimated per unit fault distance, and identifying as a potentially faulted segment if the estimated fault distance for the segment is between about zero and about one.

Abstract: Método para discriminar llamas entre una primera llama con un número predeterminado de atributos asociados a llama y una segunda llama con un número predeterminado de atributos asociados a llama, donde dicha primera y segunda llama son vistas por un escáner de llama único (32) y dicho escáner de llamas (32) produce una señal indicativa de dicha primera y segunda llama, dicho método comprendiendo: el procesamiento simultáneo de dicha señal indicativa de llama para mejorar uno o varios de dicho número predeterminado de atributos de llama asociados a la primera llama y para mejorar uno o varios de dicho número predeterminado de atributos de llama asociados a la segunda llama; dicho método se caracteriza por determinar cuando dicho uno o varios de número predeterminado de dichos atributos de llama mejorados asociados a la primera llama excede un umbral predeterminado asociado (46); y por determinar cuando dicho uno o varios de dicho número predeterminado de los atributos de llama mejorados asociados a la segunda llama, exceden un umbral predeterminado asociado (48).

Abstract: When a fossil fuel well is producing fossil fuel, lift gas injected into the well to bring the naturally occurring fluids in the well to the surface along with the fossil fuel and the plunger if the well has a plunger. An instrument is programmed to use the predetermined criteria to dynamically control the rate of injection of the lift gas into the well.

Abstract: Ein Verfahren wird bereitgestellt zum Analysieren und Diagnostizieren eines Großprozessautomatisierungs-Regelsystems mit einer Vielzahl von Regelschleifen. Bewertungen für vordefinierte Leistungskennzahlen (KPIs) werden automatisch für Regelungs-, Prozess- und Signalabschnitte jeder Regelschleife erzeugt. Die automatisch erzeugten Bewertungen der vordefinierten KPIs können in einer graphischen Benutzerschnittstelle (GUI) eines Computers angezeigt werden. Ein Benutzer kann die automatisch erzeugten Bewertungen der vordefinierten KPIs ändern. Unterschiedliche Datenansichten können auch in der GUI angezeigt werden. Die Datenansichten enthalten Zeitreihentrends für eine gemessene Prozessvariable, eine Conrollerausgabe, einen Controllersollwert und einen Fehler, als auch Controllerparameter-Gruppierungsansichten in zweidimensionalen und dreidimensionalen Diagrammen.

Abstract: Una caja para transformador tiene una cubierta y umbral unidos a un tanque. La cubierta es retráctil sobre bisagras conectadas a la cara superior del tanque. El umbral se fija a la cara frontal del tanque cerca de la base y tiene una puerta que desciende a una posición expandida. Cuando la caja está en una posición cerrada, la cubierta y el umbral se encuentran con la puerta con umbral completamente retraída a lo largo de una superficie de contacto a prueba de manipulación. Una superficie de contacto a prueba de manipulación se forma en el lado de la caja por una saliente en los paneles laterales del umbral y un deflector en los bordes inferiores de la cubierta. Una superficie de contacto a prueba de manipulación se forma en la parte frontal de la caja por una curvatura y el borde formado en el panel frontal de la cubierta, en cooperación con una porción con huecos formada en la puerta.
