An assembly or panels of rectangular shape, as for example, a floor, in which the panels comprise upper and lower rigid sheets separated by a core, elongated fittings extending along adjacent edges of adjacent panels and having lateral extensions received between edge portions of the sheets of the panels. Each fitting has an upwardly open channel located beyond the edge of the associated panel. Adjacent fittings, and hence adjacent panels are secured together by elongated connector strips which ...

A plug-in interconnection for optical and avioptic cables for connecting those cables into equipment such as circuit boards having fiber optic circuitry running in a plane normal to the axis of the plug-in interconnection. In the interconnection, a male connector having the end of the optical fiber means of the cable projecting from the end thereof is plugged into an on-axis female receptacle. In the receptacle, an aperture normal to its axis receives either the end or light from the end of the ...

Liquid crystal elements are interconnected in an array of rows and columns, which are not independent of one another, and are addressed by pulsed signals which together reduce the number of leads N required to operate the display. The interconnection scheme includes connecting together the last column to the second row, the penultimate column to the third row, etc., and the first column to the last row. In one embodiment for randomly accessing the display, the addressing scheme divides a row-sel...

An all electronic interconnect system having high flexibility, low cost, and higher reliability. A central matrix is formed from a multiplicity of solid state analog switches in which each switch is controlled by a digital address. Each switch can connect a common switch point to one of a multiplicity of outputs. For use with digital devices such as computers and peripherals, a multiplicity of rows of the matrix may be connected to accept an N-bit parallel byte and to output such an input select...

An electronic circuit interconnection system provides high density mounting on ceramic chip-carrier integrated circuit devices or other beam-lead, dual-in-line (DIP), tape-automated-bonded (TAB), flip-chip, or direct-mounted i.c. devices with wire-bonded interconnects or the like on an economical, dimensionally-stable, interconnection substrate which has high heat dissipating properties. The substrate has glass components which are fused onto etched metal patterns and which are proportioned rela...

An interconnection mask which is sandwiched between two members to be bonded together is comprised of a thin sheet of preselected material which has a plurality of apertures therein which are positioned, sized, and shaped to define the common bonding areas between the two members whereby structural failures induced by bonding and loading characteristics of the two members are minimized. A method for making an apparatus which utilizes the interconnection mask comprises the steps of preparing a ma...

Communications networks are interconnected by a bridge which allows the stations on each network to communicate with those on the other netowrk. Each station has an identifying address unique in the system. Data is transmitted in the form of packets each containing a source address and a destination address. The bridge includes a table holding addresses of stations in the first network. Whenever the bridge receives a packet from the first network, it compares its destination address with the con...

An electrical interconnection device intended for interconnecting an array of conductors in a cable to conductors on a substrate is disclosed. The device is comprised of a spring metal member having means securing said device to a substrate, a stamped and formed body with a first and second section joined by an intermediate bight. The first and second sections are mutually relatively deflectable about the bight to a second position and a locking means to retain said device in its second position...

An improved tower foundation is provided which is inexpensive to manufacture and when installed, serves to securely support a leg of power transmission towers and the like. The tower foundation hereof includes a screw-type earth anchor member having a tubular cavity at the uppermost end thereof. An elongated tower leg connector member is positioned and secured in the cavity of the installed anchor by an initially flowable, solidified material (preferably a sand/epoxy resin mixture). The tower le...

A circuit interconnection device for mechanically retaining and electrically connecting a planer substrate such as a thick/thin film circuit to a printed wiring card. The circuit interconnection device is characterized by a generally rectangular device body having planer sidewalls defining a hollow interconnection post receiving area therebetween. A pair of ears extend from a bottom edge of a front wall arranged to have an edge of the substrate rest thereon. A pair of substrate spring members ex...
