  • Process for the preparation of benzimidazo[1,2-a] benzimidazoles
    Patent number: 10570136
    Abstract: The present invention relates to process for the preparation of a compound of formula (I), comprising heating a compound of formula (II) in the presence of a catalyst and a base in a solvent at elevated temperature. The compounds of formula (I) can be produced by the process easily, with excellent yield and purity and at low cost.
    Type: Grant

  • Method and apparatus for generating fuel injection valve control pulses
    Patent number: 4140087
    Abstract: The air flow rate and the speed of an internal combustion engine are sensed and translated into pulse trains of variable frequency. During a time interval defined by the rpm related signal, a digital counter receives and counts the air flow rate frequency. Subsequently, the contents of this counter are counted out by a pulse train whose frequency is adjustable depending on other engine conditions such as start-up, warm-up, idling, full-load and the like. The apparatus also includes circuitry for generating a control pulse of minimun length.

  • Internal combustion engine monitor system
    Patent number: 4024850
    Abstract: A sensing means is provided to monitor combustion of fuel and air supplied to an internal combustion engine, for example by sensing ignition pulses, combustion pressure, or cylinder temperature. Signals, as sensed, are evaluated and if one of these signals is beyond a certain threshold (e.g. extreme with respect to a set value, or with respect to an average of all signals) as sensed by threshold switches, supply of the combustible fuel-air mixture to the specific cylinder is interrupted.
