Electricity: magnetically operated switches, magnets, and electromagnets April category listing, related patent applications 04/10

20100102905 - Electromagnetic switch for starter: There is provided an electromagnetic switch, for a starter, that is capable of preventing a defect caused by the formation of a leakage circuit between the battery terminal and the motor terminal, even in the case where the electromagnetic switch is flooded with water. On the outer surface of a... Agent: Sughrue Mion, PLLC

20100102907 - Compact wireless recessed sensor with plunger switch: A compact wireless security sensor having a magnetically operated plunger switch. The compact nature of the sensor of the present invention makes it ideal for being substantially concealing into a door frame or window as part of a wireless security system. The sensor unit includes a housing having an inner... Agent: Kathleen T. Petrich

20100102906 - Magnetically operated switch: A magnetically operated switch is disclosed, which has at least two electrical contacts and a permanent-magnet actuation device, at least regions of which are electrically conductive, which contacts and device can be arranged in a common housing. The magnetic actuation device in a first end position electrically conductively bridges the... Agent: Buchanan, Ingersoll & Rooney PC

20100102908 - Annular multi-cell endless box girder apparatus for a quench avoidant coldmass in an mri magnet: An apparatus for MRI magnets allows shorter bores with strong homogenous imaging fields comprising an extremely rigid box girder for to prevent magnet quench due to deformation. The coldmass of the magnet comprises at least three co-axial cylinders as formers for superconducting coils and further comprises a plurality of annuluses... Agent: Patentry

20100102909 - Solenoid plunger housing made of metals of different magnetic permeability: A solenoid plunger housing including at least one electric coil equipped with windings, as well as at least one solenoid plunger cooperating with it, which, as a function of its plunging depth into a coil opening of the coil, brings about a different inductance of the coil. The solenoid plunger,... Agent: Kenyon & Kenyon LLP

20100102910 - Austenitic iron-nickel-chromium-copper alloy: s

20100102911 - G-force emulator - the power source of c-m3: Gravitational force is a consistent process of attraction. Emulating such phenomenon can be done by the use of spring, steel (and/or magnet) and magnet (and/or electromagnet). Although spring works in repel action instead of attraction, the outcome is exactly the same as gravity. By placing a steel (or magnet) and... Agent: Miss Mary Grace Soriano Timcang

20100097165 - Solenoid assembly with shock absorbing feature: A solenoid assembly includes a solenoid having a coil provided with a passageway and a plunger movable within the passageway upon application of electrical power to the coil. A frame holds the solenoid and includes a backstop movably mounted in the frame extending into the coil passageway. The backstop is... Agent: Andrus, Sceales, Starke & Sawall, LLP

20100097166 - Solenoid and actuating element with solenoid: The invention refers to a solenoid with a coil which can be current-fed, the resulting magnetic field moving an armature. The armature acts, if necessary, on an actuator. Furthermore, the solenoid has at least one pyrotechnic actuation for the armature or the actuator.... Agent: Jacobson Holman PLLC

20100085135 - Switching device unit for switiching at least two operating states: A switching device unit is disclosed for switching at least two operating states of at least one consumer to an at least two-phase electrical supply system by way of switching elements. At least one embodiment of the invention specifies a switching device unit which has as simple a construction as... Agent: Harness, Dickey & Pierce, P.L.C
