Abstract: An axially and radially compact rectifier assembly for installation in alternator rotors (16). The assembly includes two spaced plates (30, 32), each mounting diodes (50) which are arranged to extend axially toward the plate on which they are not mounted. The axial extension of the diodes (50) provides for radial compactness. The diodes (50) on each plate (30, 32) are staggered with respect to the diodes (50) on the other plate (30, 32) so that they may nest between one another thereby providing axial compactness as well.

Abstract: A fuel system bubble dissipation device wherein fuel is delivered through a fuel line (not shown) from a fuel tank (not shown) to an engine. The device includes an ejector (30) having a casing (35) with a fuel flow passage (36) connected into the fuel line and a nozzle (37) extending into said fuel flow passage (36). The nozzle (37) is supplied with pressurized fuel to induce a higher pressure in the fuel flowing through the ejector (30). The bubble accumulation chamber (25) is associated with the fuel line and the ejector (30) to provide a reservoir for fuel passing into the ejector [(37)] (30) and to hold air bubbles separated from and above the fuel. A bubble evacuation passage (55) with an entry end (56) connects the upper end of the bubble accumulation chamber (25) to the fuel flow passage of the ejector (30) whereby air and vapor can be drawn from the upper end of the bubble accumulation chamber (25) and mixed with fuel flowing through the ejector (30). The bubble evacuation passage (55) is of a size to control the rate at which air and vapor are drawn from the bubble accumulation chamber (25).

Abstract: An improved control system for a driven cable reel (18) mounted on a vehicle (12) wherein the reel (18) is adapted to pay-in and pay-out electrical cable (14) to supply power to the vehicle (12), such as a mine car. The control system modifies the torque supplied by the reel drive so as to maintain a relatively constant tension on the cable (14). The improved control system has a first or basic output which provides high torque when the reel (18) is paying in cable (14) and provides lower torque when the reel (18) is paying out cable (14), the difference in drive torque being necessary to compensate for the reversal of frictional characteristics during paying in and paying out of the cable (14). The control system further provides a transient condition output signal to modulate the drive of the cable reel (18) in a manner which compensates for acceleration and deceleration of the cable reel (18) to reduce cable (14) slack and prevent a sudden increase in cable (14) tension which could cause cable breakage.

Abstract: A high temperature electrical insulation system is provided by forming a winding in an electrical device from a conductor that is pre-coated with a first layer of at least partially cured inorganic material. A second layer of inorganic material is applied, either during or just prior to forming the winding, over the first layer in order to seal any cracks in the first layer. The resultant electrical insulative coating is cured following the forming process, essentially at room temperature. The insulation system provided is thus totally inorganic, and its manufacture does not require the use of organics, or heating to high temperatures to cure the coating or to cause pyrolysis and/or volatilization of organic elements, as did prior electrical insulation systems. Furthermore, because no organics are utilized in either the manufacture or operation of the insulation system, there is no residual carbon in the resultant coating. The problem of reduced dielectric strength - caused by residual carbon - which plagued some prior attempts to develop polymer based high temperature insulation systems, is thus eliminated. By utilizing only inorganic materials, the insulation system provided is capable of operating satisfactorily for extended periods of time at temperatures in excess of 500 DEG F.
