  • Publication number: 20140184364
    Abstract: Certain aspects and features of the present invention are directed to a supercapacitor device that can be disposed in a wellbore through a fluid-producing formation. The supercapacitor device can include a body that can be disposed in the wellbore, a supercapacitor disposed in the body, at least two terminals disposed at least partially outside the body, and an actuation mechanism. The supercapacitor stores energy. The terminals can be electrically connected with the supercapacitor. An electrical connection between the supercapacitor and the terminals can cause the energy to be discharged from the supercapacitor in response to a conductive material providing an electrical path between the at least two terminals. The actuation mechanism can selectively prevent a deployment of the supercapacitor device in the wellbore from causing a discharge of the energy from the supercapacitor.

  • Patent number: 8514037
    Abstract: A device and method for operating automotive battery system relays and related switches. By aligning a magnetic field with a direction of current flow in a contact plate disposed between magnets that are producing the field, a generated Lorentz force can be used to promote arc extinguishing during a relay opening sequence, while simultaneously reducing the tendency of the Lorentz forces to interfere with the operation of a solenoid or other switch-activating mechanisms. By using a rotary-based mechanism to establish contact between a contact plate and current-carrying terminals, the likelihood of inadvertent opening of the relay is reduced. Such devices and methods may be used in conjunction with hybrid-powered and electric-powered vehicles.

  • Patent number: 8476993
    Abstract: A switchgear motor operator having its motor shaft coupled to the output member of the operator, that connects with the power switch, through a drive assembly which includes a first drive element continuously linked to the motor shaft, but not to the output member, and a second drive element continuously linked to the output member, but not the motor shaft. Temporary engagement of the mentioned drive elements, with motor operation of the power switch, is effected by a transducer with a movable part such as a solenoid actuated pin that couples the motor of the motor operator to the output shaft. The inherently decoupled state allows manual operation by an operating member, without any turning of the motor or engaging of the temporary force transfer parts during the manual operation. A lockout device with a solenoid deactivation mechanism disconnects the solenoid for motor testing without operation of the power switch.

    Abstract: An electro-mechanical actuator having means for transmitting motion, in the final part of a stroke performed by a system comprising a worm shaft and rider nut coupled through gearing with an electric motor, to an auxiliary interrupter for breaking the power supply to the motor. Two control levers are provided, these being coupled together, and being rotated, about a perpendicular axis, by a cursor which is fixed to the nut that slides on the worm shaft. The pivoting of the said levers is blocked during the movement of the drive shaft driven by the system consisting of the worm shaft and nut. By contrast, the levers pivot during the final part of the movement of the cursor. The distance through which the levers move in pivoting is large enough to avoid any need for the auxiliary interrupter to be a high precision component.

  • Patent number: 6992256
    Abstract: A disconnect mechanism for an electrical system that is integrated with the enclosure of the system, yet includes an external handle for closing and opening the electrical circuit. The invention utilizes the system's circuit breaker to switch the current on or off, eliminating the need for a separate external disconnect. Moving parts are limited to an external actuating handle connected by a shaft to an actuating arm, which has an opening whose inner edges press against a pin connected to the circuit breaker to trigger its movement between the on and off positions. Automatic tripping of the circuit breaker during a system overload moves the external handle to the off position, furnishing visual evidence of the systems working status. A watertight seal maintains the integrity of the electrical system's enclosure.

    Abstract: A coating and developing apparatus has an interface section equipped with a temperature adjuster (a cooling unit). A temperature-raised substrate due to exposure on periphery of the substrate outside a circuit-forming area thereon is adjusted to a predetermined temperature by the temperature adjuster and then transferred to an exposing apparatus. The temperature adjustments before exposure provide almost the same temperature over many substrates to be transferred to the exposing apparatus for less thermal effects to exposing processing, thus achieving high yields. The interface section is further provided with first and second transfer mechanisms, the first serving to transfer substrates between the processor and the exposing apparatus and the second serving to transfer substrates to each unit of a shelf section, for high transfer performance, thus achieving high throughput.

  • Patent number: 6577214
    Abstract: A sliding cover plate for the adjustment screws of a circuit breaker is slidably mounted on the housing of a motor operator. The sliding adjustment plate includes snap-in tabs for engaging slots within the motor operator housing, permitting the cover to be snapped in place, and then slidably moved between a position wherein the adjustment screws are covered, and a position wherein the adjustment screws are exposed. The cover may be secured in the position wherein the adjustment screws are covered. The cover includes a first portion defining apertures corresponding to two adjustment screws, and a third, detachable portion defining an aperture for a third adjustment screw, thereby permitting the cover plate to be utilized with both three-pole and four-pole circuit breakers.

  • Patent number: 6423917
    Abstract: A motor operator for a circuit breaker is disclosed. The motor operator includes a motor drive assembly connected to a mechanical linkage system for driving an energy storage mechanism from a first state of a plurality of states to a second state of a plurality of states. The motor operator also includes an energy release mechanism coupled to the mechanical linkage system for releasing the energy stored in the energy storage mechanism. The mechanical linkage system includes a recharging cam being driven by the motor drive assembly. The recharging cam rotates a drive plate rotatably mounted to the system. A linear carriage is coupled to the drive plate and the linear carriage manipulates an operating handle of a circuit breaker. The recharging cam is disengaged from the drive plate when the energy storage mechanism is compressed into an energy storage state and the drive plate is latched into a position corresponding to the energy stored state.

  • Publication number: 20020093405
    Abstract: An electrically powered, fast acting transfer switch utilizes a single action solenoid that, alternately, through a mechanical assembly, moves the handle of one electric power switch between OFF and ON positions. A coupling including a rigid strap operates the handle of a second electric power switch oppositely between ON and OFF positions. The mechanical assembly includes an electromagnet drive plate to which the electromagnet of the solenoid is secured and an armature drive plate carrying the solenoid armature. A latch mechanism alternately holds one drive plate and then the other stationary so that the electromagnet and armature alternately move to effect reciprocal movement of the handle of the one electric power switch, and through the rigid strap, the handle of the second electric power switch.

  • Patent number: 6380830
    Abstract: A low-voltage circuit breaker includes a retrofittable motor reset mechanism. Its output shaft can be coupled to a charging shaft, mounted in a bearing block, of the spring energy store of the low-voltage circuit breaker. Centering elements are provided on a flange of the bearing block of the charging shaft of the spring energy store so as to engage in mating elements on the gearbox output of the motor reset mechanism, in such a way that the motor reset mechanism can be pushed axially into these centering elements with little movement in the direction of the charging shaft. In order to lock the motor reset mechanism in the pivoting direction, a fixing element is provided at a point fitted at a specific distance from the centering elements. The motor reset mechanism is fixed axially in the centering elements of the flange of the bearing block of the charging shaft of the spring reset mechanism, and in the coupling of the charging shaft.
