Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: A strain relief housing for use in a communication plug terminating a cable carrying a plurality of conductors. The housing includes a plurality of prongs for segregating the conductors from a cable that is received through a passage in the housing. Means for anchoring the cable in the passage serve to effectively eliminate stress on the electrical connections with the conductors inside the plug. In a preferred embodiment, the strain relief housing segregates the conductors in a substantially circular array, largely conforming to the arrangement of the conductors in a round cable.

Abstract: A jack assembly is provided in which the central body of the assembly includes integrally cast posts for aligning and securing follower springs, wiper springs and spacers. To assemble the jack, the follower springs, wiper springs and spacers are stacked onto the posts and then secured with a pushnut that engages the posts with a friction fit, avoiding separation from the central body.

Abstract: Disclosed is a method and apparatus for mounting connectors to printed circuit boards. The circuit boards are aligned with the connectors by inserting spring-loaded pins through holes in the board. The connectors are then mounted by inserting pegs on the connector housings through the same holes which include the pins. The pins are displaced from the holes as the pegs are inserted therein while alignment is maintained.

Abstract: Paramagnetic articles such as a stem (14) and an armature (17) are placed into mutual coextensive alignment with a gap (19) of a predetermined width between adjacent portions of such articles. To repetitively establish the predetermined gap between successive groups of such articles, a first of such articles is guided tangentially into a magnetic field. A resulting force on such article (14) draws the article against a first stop surface. The article becomes magnetically polarized, such that when the second article, such as the armature (17) is guided into coextensive alignment with the first article, the second article becomes attracted to the first article to be drawn against a stop surface opposite to and spaced from the first stop surface by a dimension equal to the predetermined gap width.
