Abstract: A coupling device for use with a primer and blasting cap in demolition fig devices and the like. The device includes a body portion defining a straight line path from the primer to the blasting cap. Also included is a moveable slide positioned in the body to block the straight line path and moveable to clear that path. A spring is used to act on the slide to clear the path, and a safety pin holds the slide against the spring until firing is desired. A time delay device such as a liquid annular orifice dashpot delays movement of the slide. A preferred embodiment uses two slides and two springs to first clear the path and second place a blasting cap lead in alignment on the path when the slides clear the path.

Abstract: An integrated circuit (IC) and lead frame assembly comprises a first TAB segment having a plurality of leads having inner and outer ends. The inner ends are connected to bumps formed in a square pattern adjacent the periphery of the IC. A second TAB segment includes a plurality of leads having inner and outer ends. The inner ends are connected to a second set of bumps formed on the IC inwardly from the first set. The outer ends of the leads on the second TAB segment are connected to traces on the first TAB segment which are interleaved between the leads on the first TAB segment. The outer ends of the traces and leads on the first TAB segment thus connect to all of the IC bumps. This arrangement increases the number of connections which can be made to the IC.

Abstract: A technique and apparatus for detecting the internal rotation of the principal axes in the fabrication of birefringent fibers is based upon a new method for producing and interpreting the interference fringe pattern backscattered power from a birefringent fiber side-illuminated with a laser light source to determine the internal orientation of the strain-inducing axes. An apparatus employing this technique for controlling internal rotation of the principal axes provides for adjustment of the orientation of at least one of the traction surfaces pulling the fiber during drawing fabrication to maintain parallel alignment of the planes of rotation of the surfaces to reduce the fiber rotation-inducing motion which leads to internal rotation of the fiber's principal axes.

Abstract: A portable performance platform for the performing arts is disclosed that, in the stowed configuration, can be transported along roads and highways, and, in its unfolded configuration, presents an extended performing area having an overhead canopy. The platform includes a chassis mounted on ground engaging wheels. A pair of spaced apart, upright standards are positioned along one side margin of the chassis. Each standard includes an articulated arm that can be shifted between a stowed position (for transport of the platform) and an extended position (when the platform is set up for a performance). The articulated arm includes two arm members, and panels are fixedly carried by each of the arm members. In the stowed position, the panels make up a top wall and a sidewall of a staging compartment, and, when the arms are in the extended position, the panels provide a canopy over the performing area.

Abstract: An all solid-state variable transmission electrochromic device has a source of charge compensating ions. An inorganic oxide counterelectrode film which on reduction with the accompanying insertion of the charge compensating ions increases its transmission of light of predetermined wavelength is separated from a primary electrochromic film which on reduction with the accompanying insertion of the charge compensating ions decreases its transmission of light of predetermined wavelength by an insulating electrolyte film that transports the charge compensating ions. First and second electrodes are contiguous with the inorganic oxide counter electrode film and the primary electrochromic film, respectively, and separated by the three films.
