Abstract: This invention relates to a blocking oscillating converter for transferring energy from a source of power, such as a vehicle battery, to a storage means, such as an energy storage capacitor in a capacitor discharge ignition system. A novel control and feedback circuit incorporated in the blocking oscillator allows the drive level to the switching transistor to be controlled in response to the peak current in said transistor as well as the output voltage of the blocking oscillator. Furthermore the control circuit allows the blocking oscillator to be turned off during the short period of time after each spark discharge that is needed for turnoff of a switching device used to control that discharge.

Abstract: This disclosure relates to apparatus for selectively limiting the speed of an internal combustion engine by momentarily removing the ignition voltage to the spark plug of said engine at one or two preselected speeds below the maximum speed capability of the engine. Said speed limits are activated in response to electrical input signals generated by switches controlled by the operating condition of a vehicle driven by said engine. Such electrical signals could be determined by whether the vehicle transmission is in reverse and/or switches selectively operated by the operator. This emitter therefore controls the engine and thus vehicle speeds to increase the safety of the vehicle under selective operating conditions.

Abstract: Disclosed is an electrical power system adapted to receiving power from a source of alternating current, typically a small alternator, and supplying a direct current potential to a load. This power system includes two stages, the first stage comprising switchable rectifying devices such as silicon controlled rectifiers which interact with the impedance of the alternator or other source of alternating current power as a switching regulator to create an intermediate direct current potential.The second stage operates from this intermediate direct current potential to produce a slightly lower output voltage, and creates a more accurate regulation than is possible with the first stage alone, the second stage greatly reduces ripple and high frequency noise components contained on the output of the first regulator stage. The second stage serves as an active low pass filter tuned to a desired DC voltage.

Abstract: A device for indicating the interval for the flow of a predetermined volume of fluid. The fluid flow measurement device includes a housing having a cavity therein for being interposed along a fluid line. A flexible diaphragm having a convolution therein is included within the cavity for dividing the cavity into a first and second chamber. The flexible diaphragm prevents the flow of the fluid between the first and second chambers. A fluid port connects the second chamber to the fluid flow line. A fluid outlet connects the first chamber to the fluid flow line. The apparatus also includes a bypass for diverting the fluid flow from the fluid port of the second chamber through a fluid inlet into the second chamber, whereby the fluid flowing into the second chamber will displace the flexible diaphragm into the first chamber thereby expelling the predetermined volume of fluid from the first chamber.

Abstract: This disclosure relates to a pulse generator for triggering successive energy discharges such as in automotive or other ignition systems and the like, which generator comprises a magnetic circuit a portion of which is interrupted by a conductive vane the position of which controls the production of the pulses and at least one winding encircling a portion of said magnetic circuit, means connecting said winding to the output of an amplifying means, said components connected to produce as negative feedback at the input of said amplifying means the total voltage across said winding; the magnetic circuit and electronic circuitry connected thereto being so arranged as to minimize the number of components which must be placed in close physical proximity to the rotating vane, generally in the distributor of the engine, and to also minimize the number of interconnecting leads from the vane location to the balance of the ignition system, thus producing a small, inexpensive and highly accurate pulse generator.

Abstract: This invention relates to an electrical latching circuit, relatively impervious to noise pulses, for being used with a power source for supplying current through a circuit line to an electrical load and auxiliary circuits coupled thereto. The latching circuit includes a thermally activated variable resistance element interposed along the circuit line, a control device interposed along the circuit capable of allowing the current flow therethrough responsive to the resistance of the variable resistance element, exceeding a preselected value, and a circuit for varying the resistance of the variable resistance element whereby the current supplied to the electrical load through the current line is capable of latching on only by increasing the resistance of the variable resistance element.

Abstract: A semi-conductor voltage regulator includes a dual transistor differential amplifier pair adapted to so as not to be damaged by reverse voltages during the application of either polarity of alternating current to the associated sensing network. The sensing network includes resistors, the value of which are selected to provide an offset current during one polarity of alternating current with respect to the other polarity. A diode is coupled with the differential amplifier transistor pair in order to protect those devices and the load from high, suddenly-applied or transient voltages generated externally or by internal switching within the regulator.
