Abstract: Hand-held devices that can be used to quickly install flashover protection covers around energized electrical conductors and equipment are provided. Each device includes a guide assembly that defines a pair of spaced-apart, converging passageways that are configured to slidably receive the elongated edge portions of a flexible panel therethrough. The converging passageways force together the opposite edge portions of a flexible panel being advanced through the guide assembly.

Abstract: A cover installation apparatus installs continuous lengths of flashover protection covers around energized electrical power lines. The apparatus includes a cover assembly housing that takes a flat, extruded length of material and forms the material into a closed circular shape surrounding a power line. The cover assembly housing includes opposite first and second ends, with an inlet port in the first end and an outlet port in the second end. An interior passageway extends along a longitudinal direction from the inlet port to the outlet port and is configured to receive the power line therethrough. The interior passageway also provides a path for the flexible panel to follow from an uninstalled configuration to an installed configuration surrounding the power line.

Abstract: Multiplexed joining of solder bumps to various substrates for assembly of an integrated circuit package includes placing a semiconductor substrate (312) having solder bump structures (314) in contact with a ceramic substrate (320 having chip pads (322, 334), and placing this structure in contact with ball grid array spheres (352) in order to form a CBGA (360) in a single flow process.

Abstract: The present invention relates to a speed protection system for monitoring the speed of a rotating shaft in a machine. The speed protection system includes a first speed detection system, a first time delay system, and a first time delay system. The first speed detection system determines a first rotational speed of the shaft in the machine. The first tripping system is coupled to the first speed detection system and to the machine. The first tripping system trips the machine to stop the rotation of the shaft when the first rotational speed is either less than a minimum speed or is more than a maximum speed. The first time delay system is coupled to the first tripping system. The first time delay system prevents the first tripping system from tripping the machine if the first rotational speed is less than the minimum speed until either a first period time has expired or the first rotational speed exceeds a first enabling speed.

Abstract: An environmentally sealed splice closure (20) for buried telecommunications cables (32) and splices (33) includes a base (22a and b) having ports (31a and b) for receiving the telecommunications cables (32) therethrough. A cap (25) is received on the base (22) to form a cavity (50) within the splice closure (20). The cavity (50) is filled with a gel sealant (45 and 47). A dome (55) on the end of the cap (25) opposite the base (22) accommodates volumetric and pressure changes within the closure (20).

Abstract: A motor vehicle steering column including a first mast jacket element mounted on a body of the vehicle, a second mast jacket element telescoped into a cylindrical passage in the first element, and a split bushing between the first and second elements. The bushing has a lip on an outside surface thereof which seats against the passage in the first mast jacket element to define a closed circumferential chamber around the bushing interrupted by the split in the latter. A plastic shim is molded in place in the closed circumferential chamber by injecting liquid plastic under pressure through a port in the first mast jacket element. Liquid plastic fills the closed circumferential chamber and clamps an inside surface of the bushing against an outer surface of the second mast jacket element to eliminate lash. Shrinkage of the plastic in the closed circumferential chamber reduces the contact pressure between the bushing and the second mast jacket element to minimize frictional drag.
