摘要:
A submersible electrical connector intended for use in a power distribution network permits a metal to stripped metal conductor connection to be visually inspected and verified by the installer while eliminating many opportunities for human error present with existing connectors. The connector in one embodiment includes a generally cup or dome-shaped enclosure which is preferably transparent. An open end of the enclosure mates with a seal body and a connector plate has a number of apertures adapted to receive the bare metal ends of conductors or wires inserted through the seal body. Each aperture in the connector has an associated set screw for securing the conductor thereto. A molded seal member is adapted to mate with the seal body and to provide a water-tight connection when mated with the enclosure. The seal member has a number of seal ducts each aligned with one of the apertures in the connector. The seal ducts provide a water-tight seal around the plastic sheath of the conductor when installed in the assembly. Each seal duct initially includes a missel-shaped wire way guide plug inserted therein. Each wire way guide plug is open at the bottom to receive the exposed end of the conductor therein. The wire way guide plugs remain installed in the seal ducts to seal them until a conductor is inserted through the associated seal duct.

摘要:
A mechanical system that assembles or deploys pre-stressed structures. The assembly or deployment process outputs and elastically deforms material to form flexural members having a sinusoidal shape and stored potential energy. The sinusoidal shaped members are oriented and deployed with support members as they take shape. Sinusoidal shaped members are formed from a series of contiguous flexures; each flexure's properties may be engineered using a simulation technique. Each flexure is formed from a region of a sinusoidal member's length that begins and ends at antinodes. During assembly or deployment support members are positioned at antinodes maintaining the flexures' shapes and the assembly's pre-stressed state. By controlling the forces applied to and position of each flexure formed during assembly, the distribution of potential energy within the assembly and its secondary shape can be engineered. Elastic potential energy may be harvested from the material forming the flexural members.

In accordance with the present invention, a preferred method is disclosed for operating a transfer case synchronized range shift mechanism. The range shift mechanism can be selectively actuated for establishing a four-wheel high-range drive mode, a neutral mode, and a four-wheel low-range drive mode. The synchronized range shift mechanism is comprised of a first input gear system, a second input gear system, and an output gear system. The output gear system is comprised of a rotary output member that may be selectively engaged with either the first input gear system or the second input gear system, depending on which four-wheel-drive operating mode the vehicle operator selects. The range shift mechanism is further comprised of a synchronizing mechanism. The present invention discloses a novel method for controlling the speed of the range shift as a means for reducing the time it takes to perform the range shift.
摘要:
Oxygenated compounds are prepared by reacting olefinically unsaturated compounds with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst with suppression of the olefin hydrogenation side reaction if an acid is used in the reaction mixture. Typically, o-phthalic acid suppresses the formation of hexane and n-propanol, respectively, when 1-hexene and allyl alcohol are hydroformylated.
摘要:
The resiliently coated metallic finger seal described herein is formed of two metallic seal members being fixed together at one end with fingers projecting rearwardly therefrom. The fingers on each member are offset so that the slits of each metallic seal member are not aligned. The fingers of the two members are then encapsulated by a resilient coating material, such as a room temperature vulcanizing silicone rubber. The seal means is described as annular and can be constructed of one piece or a plurality of sections. In constructing the seal means the metallic seal members are cleaned, primed where it is desired to have the resilient coat permanently affixed, and the resilient coat is then applied. The resilient coat does not cover the entire fingers so that the proper flexibility at the hinge location will reamin. After curing of the resilient coating material a heat reflecting and lubricating material is placed thereon.
