For connecting bus bar sections, which are formed of conducting strips arranged in a channel shaped insulating member, the successive strips are connected by bending the ends of the strips upwardly in a direction opposite the opening into the channel at right angles and connecting the angular parts by bolts. The connection may be enclosed in a casing, through which a lead-in may be connected to the bolt and thereby to the parts of the bus bar.

A bus repeater circuit for interconnecting first and second corresponding transmission lines for first and second adjacent bidirectional electrical bus sections. The bus repeater circuit includes first and second current sensors associated with each transmission line to apply a bipolar signal to first and second amplifiers respectively. Output signals from a given sensor of a first polarity indicate that the associated transmission line is transmitting a signal. The associated amplifier couples ...

The bus duct hanger includes a L-shaped bracket having a vertical leg carrying a pair of oppositely disposed and laterally extending clamping members and a horizontal leg having a slotted opening receiving the lower end of a drop rod. Each clamping member has a downturned hook portion at the outer end which is adapted to receive and carry a respective outturned flange located on opposite sides of the bus duct. Each clamping member is secured to the duct housing by a screw which is tightened into...

An axle arrangement in buses in which an auxiliary axle equipped with a single wheel is provided on the side of the main axle opposite the driving engine whereby the single wheel of the auxiliary axle is disposed between the longitudinal bearers of the substructure, preferably substantially in the vehicle longitudinal center.

There is disclosed a bus control device which reduces the data traffic amount of a parallel bus to enhance the performance of the bus control device. A local CPU (111) controls a serial bus transmission/reception controller (113) to give a transmission timing to a transmission interface (120). The bus transmission/reception controller (113) transmits to a serial bus a transmission frame formed by reading predetermined transmission data from a memory (112) storing addresses of a plurality of unit...

A bus master is provided with the capability to accept a data transfer task from a CPU, which includes the performance of a predetermined sequence of data transfer operations between memory and a selected peripheral controlled by a respective controller. During any one of the operations, the bus master may be requested to relinquish the bus so that a higher priority transfer may occur or a deadlock condition resolved. In response to such request, the bus master immediately terminates the current...

A method and apparatus for connecting remote options to a digital telephone base. Physical and communications protocols for connections and a flexible control scheme which can be as simple or elaborate as a given option requires are provided. The digital telephone includes an option bay connection, having a hierarchical control protocol. The option bay connection makes available several types of information, including: local analog audio, analog voice, digital voice, digital data and telephone c...

A bus driver includes a plurality of first to m-th buffer circuits for receiving input of an input signal, a delay circuit for delaying the input signal by a predetermined time period, an n-th buffer circuit for receiving input of a delay signal from the delay circuit, a capacitor for selectively receiving input of a predetermined combination of the output signals of the first to m-th buffer circuits, and an output terminal for outputting a signal composed of the output of the capacitor and the ...

Disclosed are a system and method of transmitting data among communication nodes. A first communication node is coupled to a plurality of adjacent communication nodes. The first communication node may receive a data transmission comprising a destination associated with a second communication node. The first communication node may receive status data from one or more adjacent communication nodes through a control channel coupled between the first communication node and the adjacent communication ...

A system for electrically connecting electrical components. The system comprises a first ribbon cable; a connector cap including a track area adapted to operably engage the ribbon cable, and a connector base having a first ribbon cable receptacle area adapted to electrically engage the first ribbon cable. The connector cap includes a first pair of posts spaced a first distance apart and a second pair of posts spaced a second distance apart, the second distance differing from the first distance. ...
