Abstract: A coil for use in the voltage section of the electromagnet in electromechanical utility watthour meters comprises a thermoplastic bobbin, a length of wire, and two terminals. The bobbin has an upper flange and a lower flange connected by a central, hollow core. The upper flange supports two terminal mounting boxes in which terminals are inserted. The first and second leads (i.e., wire ends) are electrically and mechanically isolated from each other in order for the coil to withstand high voltage power surges. The upper flange also supports a step that has a recessed, side profile that guides the path of the wire to the core without introducing sharp bends or turns into the wire. Excess length of the first and second ends of the wire length are secured to tie off posts that are located on the top of the terminal mounting boxes. These posts, along with the excess wire, are removed when the terminals are inserted into the mounting boxes.

Abstract: Diamond is used as an electrically insulating substrate in multi-layer devices. In a transformer, the first electrical conductor forms a coil. The first electrical conductor is formed in a plurality of layers. Electrical carriers are formed on a layer to make an electrical path around a core of ferrous material. The second conductor forms a second coil of the transformer and also wraps around the core of ferrous material. Using diamond is advantageous in a transformer since the diamond is very effective at transferring heat from the core. The diamond also electrically insulates the various portions of the transformer. An electronic packaging concept includes mounting one or more electronic components to a substrate including a layer of diamond. The layer of diamond is sufficient to transfer heat from the one or more electronic components attached to the diamond substrate. The entire substrate can also be made of diamond.

Abstract: On transition from the superconducting state to the normal conducting state, current limiters having a high-temperature superconductor increase their electrical resistance and thereby limit an electric current which is flowing through them. To provide electrical stabilization, the high-temperature superconductor is combined with a silver foil having a layer thickness of <50 &mgr;m to form an extensive composite conductor with good conductivity. The ratio of the layer thickness of the high-temperature superconductor to that of the silver foil should be >10. To produce this composite conductor, the silver sheet is placed on one side on a 2 mm thick MgO powder layer and, on the other side, is covered with a 600 &mgr;m thick so-called green sheet which contains a high-temperature superconductor powder and an organic binder.

Abstract: An electrical switch (10) includes first and second spaced contacts (52, 56), and a rocking contact (80) having first and second arms (90, 92) in electrical contact with each other. A support (60) supports the rocking contact (80) for rocking movement in opposite first and second directions. The first arm (90) moves into engagement with the first contact (52) when the rocking contact (80) rocks in the first direction, and the second arm (92) moves into engagement with the second contact (56) when the rocking contact (80) rocks in the second direction. The switch (10) includes a member (20, 36) which pivots to effect rocking movement of the rocking contact (80) in the first and second directions. The member (20, 36) pivots in one direction a first distance to cause the first arm (90) to engage the first contact (52) and pivots in the one direction a second distance beyond the first distance to cause the first arm to slide on the first contact.

Abstract: In a lever switch assembly, a sliding portion is formed on a bracket at an area located inside a first unit case. The sliding portion is constructed so as to slide along a face inside the first unit case which is directed facing away from a second unit case. With this arrangement, a projection conventionally provided at a tip end of the bracket has become unnecessary, and an overall thickness of the assembly can be decreased. During assembly, the sliding portion is blocked by the face inside the first unit case which is directed facing away from the second unit case and therefore, the bracket will be prevented from being disengaged at a stage before the second unit case is assembled.

Abstract: The safety switch incorporates a substantially cylindrical inertial mass which is horizontally movable in all directions in a cavity of the-body of the switch. The inertial mass has a peripheral edge which is engageable with a cam action by projections of a resetting push button for returning it to a centered position. A base surface of the inertial mass has a central depression for housing the upper end of a push rod and maintaining the push rod in a position corresponding to a first state of the circuit. This base surface also has a concentric annular groove into which, when the inertial mass is in an eccentric position, the push rod enters causing the movable contact member to move to a position corresponding to a second state of the circuit. The switch also includes means for disengaging the push rod from the annular groove under the action of the resetting push button, in order to enable the inertial mass to return to the centered position.
