Abstract: A nozzle injection apparatus for use in internal combustion engines includes a fuel pump for intermittently pressurizing fuel and an injection conduit in fluid communication with the fuel pump, the injection conduit permitting the pressurized fuel to be communicated to a fuel injection nozzle. A high pressure manifold in fluid communication with the fuel pump and the nozzle is also provided to accumulate the pressurized fuel which is residually left in the injection conduit between intermittent pressurizations of the fuel. The apparatus has low opening and closing pressures when starting the engine while ensuing high opening and closing pressures during operation of the engine. Further, the apparatus maintains high residual pressure in the injection conduit which provides higher than normal pressure to the nozzle at the end of a fuel delivery cycle to subsequently reduce exhausted pollutants.

Abstract: In a calendar book each page corresponds to a part of a month and is subdivided into a plurality of fragments corresponding to the different parts of the month. The fragments of a page are releasably secured to each other for ready separation. The separated fragments of the pages may be successively removed from the stack as time ensues for continuously revealing the current date and the successive dates next-following beyond the dates of the next-to-be-overturned fragment.

Abstract: Engine fuel injector control circuitry comprising a pulse generator that duces long duration pulses. NOR gate circuitry is actuated by each pulse to operate a ramp generator. The ramp generator output changes at a rate determined by current flow generated by an engine speed sensor. Ramp generator output is applied to an input terminal of a comparator to produce rapid switching of the comparator output for starting the injection of fuel into an engine cylinder. Injection is terminated by the trailing end of the long duration pulse.
