摘要： Disclosed is a multipole high-voltage circuit breaker of the type comprising a housing into which two stationary contacts per pole extend and a rotatable current bridge which connects and disconnects the stationary contacts upon rotation thereof. Both the stationary contacts and the contacts on the movable bridge are provided with preliminary switching points or contacts and main contact points or contacts. The preliminary contact points make contact before the main contact points and break contact after the main contact points. The arrangement permits arcing at the preliminary contact points only and thereby increases the life of the main contact points.

摘要： A first deceleration sensor operates switches for energizing the release element of airbags in a vehicle, typically glow wires that will set off an explosive filling of the respective airbag. Connected through diodes to the various airbags is a circuit in parallel with the release elements of all of them which contains a fuse 49 in series with a normally closed switch 50, which last is controlled by a second deceleration sensor 52. If a short circuit or any malfunction causes any one or more of the airbags to release, since the sensor controlling the normally closed switch does not operate, the fuse blows to register a false release. The sensor controlling the normally closed switch may also control a normally open switch in series with all of the switches controlling individual airbags, so that both sensors must operate to release an airbag, and is economically combined into a mercury switch unit in which rapid deceleration moves the mercury to break one circuit and make another circuit, as distinguished from the first-mentioned sensor which operates switching transistors.

摘要： A fuel injection system of an internal combustion engine generates valve-actuating pulses for actuating electromagnetic fuel injection valves. The length, or duration, of these valve actuating pulses is a function of various engine conditions and they are generated by a pulse-length multiplying circuit from preliminary control pulses derived from two basic engine variables, e.g. engine speed and air flow rate. In order to compensate for the decreasing pressure drop across the injection valve orifice at high engine load due to increasing manifold pressure, the invention describes methods for lengthening the fuel valve-actuating pulses by engaging the pulse-length multiplying circuit, in order to change the charging or discharging times of the timing capacitor therein. Another method proposed is to engage the battery-voltage compensation circuit in the system to lengthen the valve-actuating pulses. Electronic circuitry to perform these corrections is also described.

摘要： In a known ignition system, the emitter-collector circuit of the ignition transistor is connected in series with the primary winding of the ignition coil and with a precision resistor. When the voltage across the latter exceeds a predetermined value, an auxiliary transistor is switched to a conductive state. The emitter-collector circuit of the auxiliary transistor is connected to the base of the ignition transistor and, when conductive, prevents further increases of current through the primary winding of the ignition coil. To protect this circuit, a series circuit including two Zener diodes is connected between the base and collector of the ignition transistor. Further, a voltage divider is connected in parallel with the emitter-collector circuit of the ignition transistor and an additional resistor is connected between the base and the emitter thereof. When overvoltages across the primary winding cause breakdown of the Zener diodes, the current through the Zener diodes is blocked from the emitter-collector circuit of the auxiliary transistor either by a diode or by a blocking transistor having an emitter-collector circuit connected in parallel with the base-emitter circuit of the auxiliary transistor. The blocking transistor is maintained in the conductive state blocking the auxiliary transistor throughout the application time of an externally applied blocking signal which is adapted to maintain the ignition transistor in the blocked state.

摘要： In order to provide for complete testing of all the components of a trigger circuit for actuating an automotive passenger restraint system, and thereby to prevent unintentional deployment of restraint systems, for example air bags, the test circuit performs a testing program which is initiated at the moment when electric power is applied to the passenger safety system. The testing program checks the operation of the electronic discriminator circuits as well as the correct operation of the power output circuit by generating a simulated triggering signal. The actuation of the passenger restraint system is prevented during the test cycle by blocking an auxiliary semiconductor switch connected in series with the power output transistor of the triggering circuit.

摘要： The cyclic control pulses for actuating the fuel injection valves of an internal combustion engine are extended during engine starting at low temperatures. The degree of pulse extension, i.e. of fuel enrichment, is made dependent on engine temperature and decreases as a function of cranking time. In addition, a repeated starting attempt will be accompanied by reduced pulse extension to prevent excessive enrichment of the mixture. The pulse extension may also be retained for a period of time after engine cranking to insure smooth running.

摘要： A monitoring resistor in series with the spark coil primary winding and the electronic interruptor switch provides a signal to an integrator for shifting the control thresholds of a threshold switch that controls the interruptor away from their quiescent values that are nearer the zero crossover of the timing voltage wave provided by an engine driven timing signal generator. The integrator output voltage remains constant during the time the interruptor switch is open. While current flows through the interruptor circuit, the integrator increases the control voltage until the primary winding current reaches a predetermined level and then decreases the control voltage until the timing wave recloses the interruptor. While the control voltage is being decreased, the coil current is allowed to rise to a limiting value and is then held constant by another circuit controlled by the monitoring resistor that slightly reduces the conductivity of the interruptor switch in its closed condition, but this occurs only while the engine is accelerating to the operating speed range. During this time the switch-on threshold for controlling the interruptor is raised towards the peak of the timing wave, but the switch-off threshold is clamped to its initial value. With further increase in engine speed, the net effect of the integrator operation changes sign and the switch-on threshold is lowered. As soon as the switch-on threshold goes below its initial value, the switch-off threshold is unclamped and is depressed along with the switch-on threshold towards the negative peak of the timing wave by the integrator action. The result is to keep the amount of energy stored in the spark coil at the time of primary circuit interruption constant over a wide range of speed.

摘要： The motor is serially connected with a diode and a sensing resistor so that half waves of one polarity, for example negative, can flow through the motor and provide, across the resistor, a voltage drop corresponding to loading placed on the motor. A thyristor is connected in parallel to the diode and reversely poled to conduct the other half wave, then the positive, if triggered. Triggering of the thyristor is controlled by the voltage drop across the sensing resistor so that, under no-load conditions, only the negative half waves will be applied to the motor, thus limiting its no-load speed but, as loading is placed thereon, increasing portions of the positive half waves are likewise passed through the motor. The diode may, itself, be a controlled diode such as a thyristor which is rendered conductive by a phase control network, thus providing speed control for the motor, controlling actually only the negative half wave but, due to sensing resistor, effectively, regulating the motor current during both half waves. The circuit uses a capacitor which is charged to the voltage forming the control voltage on the thyristor conducting the positive half wave.

摘要： To provide an undistorted square wave output signal under control of a switch subject to contact chatter so that the square wave will accurately reflect the operating instant of the switch, as commanded, regardless of contact chatter, a timing circuit is provided having a timing capacitor and a charge and discharge circuit therefor, connected to a threshold circuit, the threshold circuit response level and the charge circuit of the timing capacitor being dimensioned to cause the capacitor to charge to a level such that the threshold circuit responds only when the switch has changed state, typically closed after interrupting an inductive load, such as the primary of a spark plug, for a predetermined time period as determined by the switch contact chatter characteristics of the switch itself, for example about 0.6 to 1 millisecond in the case of automotive ignition breaker switches; a feedback connection is provided between the threshold circuit and the input stage to the circuit to disable transfer of a signal representative of change of the switch through the circuit unless the threshold level of the threshold circuit has been exceeded so that the threshold circuit could respond.
