In a fuel injection pump which is capable of adjusting the fuel injection quantity by the ON/OFF control of a solenoid valve 7, the solenoid is driven by a first pulse in response to an injection timing signal and by a subsequent second pulse whose duration depends upon the desired fuel quantity. The second pulse is administered when it is detected that the valve has responded to the first pulse. ...

An output stage device for an enhanced differential current switch. The output stage receives a differential signal pair (COC,COT) from a prior logic stage and must shift the output signals (OUTC,OUTT) to the levels necessary for the next stage. The output stage has a differential pair of emitter followers that are capacitively cross coupled. Capacitors (Cc,Ct) couple the collector of a first tran...

The invention refers to floor tiles and a method for their production. The tiles are produced on the basis of a mix of hydraulic binder, polymer, filler, sand, colour pigments, additives and water. The binder content is 15-40 % by weight and the polymer content is 3-10 % by weight, calculated as percentages of the dry constituents. The tiles are produced from a castable mix which is made to harden...
