Abstract:
An actuator system for use in selectively engaging an input to an output. The actuator system includes an input sub-system having an input component configured to connect to an input element which is in turn connected to a work source. The actuator system also includes an output sub-system being connectable to the input sub-system for receiving work from the work source via the input sub-system. The actuator system further includes an actuator sub-system having an active material and an actuating component. The actuator sub-system is configured so that the active material, when activated, causes the actuating component to move from a first state to a second state to disengage the input and output sub-systems.
Abstract:
A mine door control system and method that uses sensor input from a plurality of sensors corresponding to at least one of a position of at least one associated opposing wing mine door and a path through the at least one associated mine door to determine at least one predefined action in accordance with received sensor input. A control command is then communicated a drive mechanism associated with the at least one associated mine door, the control command including instructions for operating the drive mechanism in accordance with the at least one predefined action.
Abstract:
A system, method, and computer storage configured for determining period-ending positions of multiple parts movable by select actuation of corresponding active materials. The operations include receiving, from a work-source sensor, work-source input indicating a distance moved by the work source and a direction of the movement, and determining, based on the work-source input and a first and second status histories, corresponding to a first and a second part, respectively, first and second distances travelled by the parts, respectively. Operations also include calculating, based on the first and second distances determined and first and second period-starting positions, corresponding to the first and second parts, respectively, first and second period-ending positions for the first and second parts, respectively.

Abstract:
A high-pressure mine door assembly for use in mine shafts configured with opposing wings, which enable the door to open and close quickly. The assembly includes a major hub and a minor hub positioned at or above the cap of the door assembly and coupled together via a connecting bar. A drive mechanism is coupled to the cap and the connecting bar, which facilitates the opening and closing of the wings of the door. The door assembly is configured in a 12-6 pitch orientation, requiring only a ⅔ rotation of the wings of the door assembly to fully open the door. Such a configuration also negates the effect of air pressure on operation of the door, as regardless of the direction of the airflow, with the airflow assisting one wing in opening and the other in closing.
Abstract:
Das für eine Trennvorrichtung vorgesehene Laufwerk (1) weist einen dem Halten eines Trennelements (6) dienenden Laufwerkskörper (102), der wenigstens ein auf einer Laufschiene (5) verfahrbares Laufrad (21) aufweist, und eine aus einem Elektromotor (11) und einem Getriebe (12) gebildete Antriebsvorrichtung (10) auf, die mit einem ersten Antriebselement (13) gekoppelt ist, mittels dessen eine Kraft auf die Laufschiene (5) übertragbar und das Laufwerk (1) antreibbar ist. Erfindungsgemäss ist die Antriebsvorrichtung (10) mit wenigstens einem zweiten Antriebselement (14) gekoppelt, mittels dessen das drehbar gehaltene Trennelement (6) antreibbar ist. Anhand des erfindungsgemässen Laufwerks (1) können separate oder gelenkig miteinander verbundene Trennelemente (6) vorteilhaft verschoben und/oder gedreht werden.
Abstract:
The invention relates to a motor-driven element (1) of a partition wall, comprising at least one motor-driven locking profile (5), for the securing and/or sealing of a motor-driven element of a partition wall, comprising at least one motor-driven sealing profile in an end position. According to the invention, the motor-driven element (1) can be controlled as simply as possible, whereby the voltage applied to the element for operation of the element is switched in an end position of the element by a switching device, such that at least one locking profile (5) is extended after reaching the end position and retracted before leaving the end position.
Abstract:
Wandelement (10) mit Speicherelement und automatisch bewegbarem Dichtelement (31,32). Wandelemente (10) mit Dichtelementen (31,32) werden bisher manuell entlang einer Tragschiene bewegt oder mittels angetriebener Laufwagen (12), die über im gesamten Verfahrbereich des Laufwagens (12) im Bereich der Tragschiene angeordnete Stromabnehmer und Stromschienen mit Energie versorgt werden, automatisch verfahren. Das Aus- und Einfahren der Dichtelemente (31,32) erfolgt manuell. Um Bewegung des Wandelements (10), beispielsweise mindestens in Teilbereichen der Tragschiene, und/oder das Aus- und Einfahren der Dichtelemente (31,32) automatisch und/oder unabhängig von einer externen Energieversorgung zu gewährleisten, ist dem Wandelement ein Energiespeicher (34) zugeordnet. Ein derartiger Energiespeicher (34) versorgt mindestens einen Antrieb (36) zur Betätigung der Dichtleisten (31,32) und/oder der Bewegung des Wandelements mit Energie. Das Wandelement (10) ermöglicht den komfortablen Einsatz von Wandelementen zur Bildung von Trennwänden.
