20090160588 - Electromagnetic operating device for switch: An electromagnetic operating device for a switch comprises a fixed yoke (1) formed by laminating square yokes and an E-shaped yoke integrally while holding the E-shaped yoke in-between, a permanent magnet (5), a moving member (2) capable of linear movement in the fixed yoke by a predetermined distance, a rod... Agent: Buchanan, Ingersoll & Rooney PC

20090160589 - Device with an electromagnet, clutch, and method for producing an electromagnet: The invention relates to an apparatus having an electromagnet, comprising a coil and magnetic-field guide means, which at least partially surround the coil. According to the invention, the coil is provided with a sprayed or cast casing, wherein the magnetic-field guide means are formed from a material which comprises ferromagnetic... Agent: Burr & Brown

20090160590 - Method and apparatus for controlling a lifting magnet supplied with an ac source: A magnet controller supplied by an AC source controls a lifting magnet. Two bridges allow DC current to flow in both directions in the lifting magnet. During “Lift”, relatively high voltage is applied to the lifting magnet until it reaches its cold current. Then voltage is lowered. After a desired... Agent: Knobbe Martens Olson & Bear LLP

20090160591 - Magnetic element: To provide a magnetic element the ends of the coil of which can be drawn out from the core easily, is compact, and further, is one in which magnetic saturation does not arise easily. A magnetic element has a core unit provided with a wound coil, a center core 105... Agent: Von Simson & Chin

20090153276 - Current trip unit for circuit breaker: A trip unit having a current carrying element, an anchor having an up and a down position, and an oscillator having a first position and a second position. The oscillator in the first position permits the anchor to move into the down position, and the oscillator in the second position... Agent: Paul D. Greeley, Esq. Ohlandt, Greeley, Ruggiero & Perle, L.L.P.

20090153277 - Relay with overtravel adjustment: An electromagnetic relay has an overtravel adjustment to set the gap in the contact arrangement. The armature is actuated by a relay coil and linked to a pusher to drive the pusher to operate the contact system. The pusher includes a rotary dial disposed in a slot on the pusher... Agent: Tyco Technology Resources

20090153278 - Vehicle switch: A vehicle switch has a case, a movable body, a spring, a magnet, a detector, and an operating shaft. The movable body is reciprocably accommodated in the case. The spring pushes the movable body in a direction away from an internal bottom of the case. The magnet is attached to... Agent: Wenderoth, Lind & Ponack L.L.P.

20090153279 - Single drive betatron: A betatron includes a betatron magnet with a first guide magnet having a first pole face and a second guide magnet having a second pole face. Both the first and the second guide magnet have a centrally disposed aperture and the first pole face is separated from the second pole... Agent: Schlumberger-doll Research Attn: Intellectual Property Law Department

20090146766 - Protection switch: A protection switch, particularly for fast switching, includes at least one single-pole protection switch module having a housing, a movable contact mounted on a switching arm for pivoting against a fixed contact between closed and open positions, a manual operating mechanism manually setting the switching arm between the closed and... Agent: Lerner Greenberg Stemer LLP

20090146767 - Ferromagnetic nanorings, mediums embodying same including devices and methods related thereto: Featured is a magnetic ring structure including at least a vortex magnetic state such as symmetrically and asymmetrically shaped nanorings, having small diameters (e.g., on the order of 100 nm). In particular embodiments, the width and thickness of the asymmetrical nanorings varies as a function of the locations on the... Agent: Edwards Angell Palmer & Dodge LLP
