Abstract: An assembly post for holding a portion of elongate objects, such as wires to be formed into a bundle, elevated with respect to a wiring layout board and for defining a turn in the objects. The assembly post comprises means for mounting the post on the layout board and holding means supported by the mounting means for holding the elongate objects.

The post also includes means for maintaining the holding means in its extended position during wiring of the bundle against a predetermined force greater than the weight of the portion of elongate objects whereby, after layout of the bundle, application of a force greater than the predetermined force causes movement of the holding means to its retracted position and permits application of a tying device and removal of the bundle without substantial interference from the post.

Abstract: A pneumatic sensor for connection to the sensor port of a bleed-pressure piloted valve and which is responsive to engagement by an article the presence of which is to be detected to block air from escaping said sensor port. The sensor includes a body having a bore and a target slightly smaller than the bore disposed in the bore and having an aperture the axis of which extends transversely to that of the bore. A tube connected to the sensing port and slightly smaller than the aperture extends through the body and into the aperture. The tube has an opening disposed in the aperture and extending generally toward the end of the target to be engaged by the article. The target is movable between an extended position and a retracted position in which the target blocks the opening, air pressure biasing the target to its extended position and the surface of the target defining the aperture being arcuate.
