Abstract: A solid state dual timer with adjustable "long" and "short" time intervals preferably providing a long normally operating period between consecutive test periods which are utilized for test purposes, wherein a "delay" interval is provided at the initiation of each test period to allow the test conditions being imposed a sufficient time to settle. A highly advantageous application resides in the field of automated lubrication systems in which periodic pressure tests to monitor system integrity are performed, for example, every hour, the tests requiring a relatively brief time interval, the "delay" interval being of a length sufficient to allow the system pressure to build up before the test instruments are activated. The normally operating interval and the test and "delay" periods are all adjustable.

Abstract: A fuel injection system for internal combustion engines includes a fuel metering and distributing assembly. The pressure gradient across this assembly is controlled by an electromagnetic fluid pressure modulator which acts on one side of equal pressure diaphragm valves. The pressure gradient is monitored by a pressure-to-voltage transducer whose signal is fed to the modulator as a control signal. One or more of the diaphragm valves may be biased in the closing direction and the controlled pressure line may also include a pressure transformer.

The valve means delivers the fuel to the engine in a quantity that varies as a function of an electrical signal representing the mathematical product obtained by multiplying a binary number electrical signal by an electrical signal representing a condition of the engine. The binary number electrical signal is a coefficient of the engine-condition electrical signal and is calculated, by a programmed digital computer, from a function or functions describing a desired relationship between the coefficent value and various electrical signals representing variable conditions of engine operation. The binary number electrical signal is repetitively recalculated by the digital computer.

Abstract: A contactless ignition system for an internal combustion engine responds to alternating current ignition signals produced in timed relationship with the engine. A primary winding of an ignition coil and a collector-emitter path of a switching transistor are connected across a direct current power source. A trigger circuit responds each cycle of the alternating current ignition signals for operating the switching transistor conductive and nonconductive in timed relationship with the engine to carry an ignition spark. A primary current limiting circuit, responsive to the voltage potential at the direct current power source, controls the amount of the base current for the switching transistor in accordance with the increased voltage of the power source, to thereby limit the primary current flowing through the primary winding to a predetermined magnitude.
