A bus strip which can be mounted on an array of terminal posts merely by pushing the bus strip into mounting engagement with a desired plurality of terminal posts is disclosed. The bus strip is a one piece configuration having a central spine with a pair of wings radiating in opposite directions from one end of the spine. The spine is provided with a series of holes adjacent the junction of the spine and wings to mount the bus strip on an array of terminal posts, and the wings are contoured so a...

A bus duct comprised of a group of elongated, flat bus bars positioned in side-by-side relation within an elongated housing, the housing having sidewalls of a height substantially greater than the width of the bus bars. In preferred form, the bus duct of this invention includes bus bars separated one from the other and from the sides of the housing only by insulator sheets positioned therebetween to form a sidewall-insulator sheet-bus bar "sandwich." Further, the sidewall-insulator sheet-bus bar...

An improved multiprocessor bus arbiter which provides dynamically prioritized access for a plurality of processors to shared peripheral devices on a common bus through bus access switches. The arbiter includes logic circuitry to which incoming bus access request signals are coupled and a memory means which stores bus access status. The logic circuit determines bus access based on the input request signal and the stored information. The arbiter is adapted to provide a cycle shared mode of access ...

A bus construction in which a structure fastened to the chassis encloses the passenger area, and has sidewalls above the bottom of the vehicle, which are provided with a longitudinal carrier section. This section is interrupted only by door cutouts, and it connects to columns. The longitudinal carrier section is, furthermore, divided into a fixed supporting inside shell and a non-supporting easily replaceable outside shell used for covering. The supporting inside shell has a bottom arch section,...

A bus bar constructed to bend connector posts and make electrical contact with them at three loci of bar points. In vertical section, vertical lines between first and second bus contact points are spaced from third bus contact points adjacent said vertical lines by a distance less than the thickness of the posts, the locus defined by said vertical lines corresponding generally with a locus of post centerlines.

A video component interconnection system includes a single signal conductor video bus serially coupled between each of the video components for conducting video signal between the components. A switch located in series with the video bus separates the continuity of the video bus when it is non-conductive. A shunt switch arrangement coupled to the video bus at its junction with the series switch, applies an impedance substantially equal to the characteristic impedance of the video bus between the...

Method and apparatus for allowing multiple enclosures (10) to be connected so that their respective motherboards (15) together define a single bus. System-wide arbitration is carried out asynchronously on an enclosure basis while arbitration within each enclosure occurs synchronously. A bus repeater (20, 25, 25') is provided at each of the upstream and downstream ends of each enclosure's motherboard. The upstream bus repeater (20) in a given enclosure is coupled by a flexible connector cable (30...

An insulating base has a plurality of conductors on one side. A plurality of mounting prongs extend through the base and project from the other side. These prongs have bent-over ends connected to the conductors. A number of small lamps are connected to the conductors. A translucent cover is seated on the base and houses the lamps. This cover has portions overlying and engaging the bent-over ends of the prongs so that pressure needed to install the unit on a panel of a dispatching board is transm...

A bus bar and duct combination as is disclosed comprising a plurality of bus bars encased and held, at a central part between end joint parts of the bus bars, within a metal duct such that the bus bars, the duct and electrical insulation members are in intimate contact to provide heat transfer from the bus bars to the duct by way of conduction.

Improved three-phase four-wire half-neutral bus duct construction. A set of bus bars is supported in a housing in four layers with three phase-carrying bus bars occupying three layers and at least two additional bus bars occupying the fourth layer.
