Abstract
Abstract 1. In telemetric apparatus for sampling in rapid succession signal voltages of a given polarity on a plurality of information inputs, a signal voltage sampling network individual to each of said inputs and having first and second terminals, a semiconductor diode having its poles sharing said first and second terminals and arranged to conduct when a voltage of said given polarity is impressed on said second terminal, a single conductor serially connecting unlike poles of neighboring diodes for providing unidirectional conduction for said signal voltages, gate means individual to each information input for applying the signal voltages thereon to said first terminal of its associated sampling network, means for applying a trigger signal input of said given polarity to said first terminal, and means in said network having at least one condition in which it is sensitive to said trigger signal input for opening said gate means for a time interval and thereafter applying to its second terminal a voltage pulse of said given polarity whereby said voltage pulse appears on the first terminal of the neighboring sampling network as a trigger signal input.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
342 words
An apparatus comprising a cable having a conductive sheath and at least one conductor surrounded by and insulated from said sheath, a display system connected to and defining the upstream end of said conductor, a plurality of similarly oriented diodes connected in series with and spaced along the length of said conductor so that voltage pulses of opposite polarity are transmitted only in opposite directions, circuit networks individual to and having upstream and downstream terminals connected in shunt with said diodes, each of said networks including an information input adapted to receive an information voltage of the polarity which is transmitted upstream, a normally closed gate connected between said information input and the upstream network terminal and adapted to be opened by a pulse of the polarity which is transmitted downstream, a flip-flop circuit having an input terminal and an output terminal and arranged to be triggered from a selected condition of rest to the alternate condition in response to a pulse on its input terminal of the polarity which is transmitted upstream and to be returned to the selected condition of rest in response to a pulse on its input terminal of the polarity which is transmitted downstream, a multivibrator for producing a relatively long pulse in response to said flip-flop circuit being moved to said alternate condition, means for differentiating said long pulse to produce leading and trailing spikes of the polarities which are transmitted downstream and upstream, respectively, means for applying said leading and trailing spikes to said gate and to the downstream network terminal whereby said gate is opened by the leading spike and the trailing spike passes downstream to trigger the flip-flop circuit in the neighboring circuit network, said gate being arranged to have an open time somewhat less than the time interval between said leading and trailing spikes so that the information voltage on said information input is transmitted to the display system prior to the triggering of said neighboring circuit network, and means for applying a triggering pulse to the upstream end of said conductor.
