enclosed electric (Total 629 Patents Found)

An electric switch operating mechanism has a base fastened over an aperture in the cabinet enclosing the switch. A driving member extends into a cup-like member and the ends of both members extend through the base and the cabinet aperture. The ends of the driving member and retainer cup have apertures therein which rec...
An electric motor, such as a rare-earth permanent magnet single airgap direct current motor is provided with generally longitudinally extensive heat transfer or cooling means comprising heat receptor elements adjacent but minimally spaced apart from and parallel the armature. These heat transfer elements are then coole...
The coil has a plastic one-piece bobbin (14), a winding (13), a terminal block (16) with a pair of holes for the terminals (17) and two connecting wires (11). The ends (12) of the winding (13) are connected to the terminals (17) embedded in the terminal block (16) and extending parallel to the bobbin axis. The terminal...
792,296. Switch cases. PRENTICE, Ltd. June 12, 1956 [June 13, 1955], No. 16956/55. Class 38 (5). Rotation of the operating lever of a switch to the off position allows a cover 11 to be removed by unscrewing a screw 24 from a plate 15. As the screw is withdrawn, a spring 12 raises an L-shaped locking-plate 17 so that a ...
382,202. Switch cases. DAVIS, R. H., 187, Westminster Bridge Road, London. March 21, 1932, No. 8414. [Class 38 (v).] In fluid tightly enclosed electric switches, e.g. for lamps for submarine use, a flexible diaphragm 13 of metal, rubber, &c., carrying a movable contact 9, is interposed between the stuffing - box 20...
<P>PROBLEM TO BE SOLVED: To prevent the increase of power consumption from increasing and to prevent a protective circuit from operating to stop a DC brushless motor, by preventing the generation of a synchronous mode. <P>SOLUTION: If an operation command is inputted at synchronous mode revolutions where a...
A sectionalized horizontal enclosing sheath for high voltage, gas-insulated electric bus apparatus comprises axially adjacent sheath members in spaced-apart relation connected by an annular coupling band. Juxtaposed ends of the band cooperate with the spaced apart sheath members to define an elongated transverse apertu...
A rotating electric machine including circumferential portions respectively corresponding to magnetic pole centers of permanent magnets and defined along the outer circumference of the rotor at a plurality of locations, with each circumferential portion extending along part of a virtual circumferential surface, which i...
ABSTRACT OF THE DISCLOSURE A sectionalized horizontal enclosing sheath for high voltage, gas-insulated electric bus apparatus comprises axially adjacent sheath members in spaced-apart relation connected by an annular coupling band. Juxtaposed ends of the band cooperate with the spaced apart sheath members to ...
