摘要： A liquid-filled cooling fin generally includes two roughly rectangular opposing fin walls separated by a relatively thin liquid space or chamber. In this invention the fin walls have reinforcing ripples to increase fin wall rigidity and resistance to deformation. The opposing walls are sealed at both ends along the depth of the fin and at one of the two edges along the height of the fin. The second, open edge of the fin is attached along the height of the fin in a liquid tight seal to a tank in which a transformer or other heat generating device to be cooled is submerged in a cooling fluid. The tank is provided with holes or other fluid passages so that cooling fluid can circulate between the tank and the fin. Cooling fluid is heated in the tank by the transformer and flows from the tank to the cooling fins, where it is then cooled by transferring heat through the fin walls to ambient air. The cooled cooling fluid then circulates back to the tank, completing a circulation pattern which is continuously repeated in operation.

摘要： A control valve includes a valve body with a fluid inlet and a fluid outlet. A valve seat is mounted within the valve body between the inlet and outlet. A valve plug is reciprocally mounted within the valve body to engage the valve seat. A plurality of valve cages are removably mounted on the valve seat and surround the valve plug. The valve cages are mounted to define axial flow galleries. One of the valve cages includes a plurality of apertures and fins that extend radially into a gallery between the first cage and a second cage. The second valve cage is adjacent to and surrounds the first valve cage. The second valve cage includes a plurality of apertures and fins that extend into the gallery area between the second cage and a third cage. The third cage surrounds and is adjacent the second cage. A plurality of apertures are defined in an upper portion of the third cage member. The first, second and third cage members may be positioned such that the apertures in each cage member are out of alignment to define a tortuous path along which fluid must flow between the cage members.

摘要： The power theft detector circuit (10, 110 and 210) detects when current is being diverted around a line conductor (20 or 220) passing through a meter housing (14 or 214). The circuit (10, 110 or 210) includes a current transformer (12, 112 or 212) coupled to the line conductor (20 or 220) within the meter and defines a primary winding (20 or 220) of the current transformer (12, 112 or 212). A secondary circuit (23, 123 or 224) includes a secondary winding (22, 122 or 226) of the transformer (12, 112 or 212) and sensing circuitry (24, R.sub.m, R.sub.1, and S; 124, R.sub.m, R.sub.1, S and 126; 232, R.sub.m, and 240) for sensing a change in the impedance reflected from the primary circuit into the secondary circuit (23, 123 or 224) when a low impedance jumper (26, 260) is connected in parallel with the line conductor (20 or 220) in the meter thereby to sense a power theft condition.

摘要： A system is disclosed which employs existing broadcast stations to transmit synchronizing and supervisory signals for use by telephone communication devices at remote locations for timing purposes and for coordinating their activities with activities at other locations. The system comprises a broadcast transmitter modified to transmit phase (or frequency) modulated digital signals, which digital signals are synchronized to the carrier of the broadcast station. The broadcast station includes equipment to both periodically transmit synchronizing and supervising signals to coordinate activity of remote devices, and to transmit messages to them. The messages are generated at a central computer location and conveyed to the broadcast station by a dedicated phone line, a microwave link, or other known methods. At remote locations a TELRAD modem includes a radio receiver to detect the broadcast signals which synchronize and supervise them and associated customer apparatus. A central control computer generates the messages. Communications to and from remote monitoring locations is also accomplished. Another important object is to provide broadcast transmissions from more than one broadcast station by providing a receiver at secondary broadcast stations tuned to the primary master transmitter, which receiver detects the transmissions of the master transmitter, modulates the repeater transmitter in the prescribed manner and retransmits the signal to extend the service area.

摘要： An electrical fuse wherein one or more portions of the fuse element are provided with two adjacent parallel weak spots separated by dielectric material or air gap, and arranged such that the direction of current flow in one of the adjacent weak spots is opposite that in the other adjacent weak spot, such that a magnetic field is generated which produces a separating force between the two weak spots. Arcs formed during the fusing of the weak spots are forced apart by the generated magnetic field thus increasing the arcs path lengths which increases arc voltage thereby forcing arc current to zero.

摘要： A unique design and construction is presented for the rotor of a dynamoelectric machine. The rotor is comprised of two end plates, bar means for holding the end plates together, a stack of pole laminations, electrical conductors wrapped about the laminations and an insulator means. The end plate contains apertures about its periphery such that the rotor can be balanced about two axis perpendicular the rotor axis of rotation by inserting masses/weights into the apertures. The insulator means electrically insulates the electrical conductors from the ends of the stack laminations, the rotor end plates and the rotor shaft. The insulator means by its unique shape further acts as a guide to position electrical conductors about the laminations during pole winding. In one embodiment the insulator means acts as a thermal insulator protecting electrical conductors when the bar means are welded to the end plates.
