An apparatus for supercharging a four cycle internal combustion engine has at least one inlet reed or check valve and at least one outlet reed or check valve associated with each cylinder of the internal combustion engine. The crankcase of the engine is maintained air tight and if the engine is multi-cylindered, the crankcase must be provided with some form of air tight separation between each cylinder inside the crankcase. When the engine is rotating, each up-stroke of each piston causes an air...

An electrically operated pulse motor having a stator and a rotor mounted within a chassis, the ends of the shaft of the rotor having been mounted in a pair of sleeves joined to the chassis, the inner diameter of the sleeves being larger than the diameter of the ends of the rotor shaft. The ends are connected with a pair of projecting semi-axles (axle shafts) of the rotor that are eccentric in relation to the shaft of the rotor and of a larger size than the aforementioned difference between the d...

The pulse transformer consists of a closed toroidal core (30), the primary winding (31) and secondary winding (32) of which are fashioned as multilayer, flexible printed circuit boards. These circuit boards have the shape of flat strips and are bent into loops. By means of pins (36-39 and 46-49, respectively), they are connected mechanically and partially electrically to a supporting printed circuit board (11). The pins connect the conductor tracks of the central layer of the flexible printed ci...

A tracking pulse detector comprising a feedback loop and means for adjustment of the detector bias to compensate for varying input signal levels whereby noise signals present at the input of the detector are maintained below the detector threshold thereby rendering the detector immune to false triggering. An AGC output is taken from a junction between resistors of a voltage divider and a capacitor is connected between the AGC output line and an OV line, the AGC voltage output being related to th...

A pulse generator, e.g. for electrical machining such as EDM, is provided which comprises: an on-time setting unit for selectively setting on-times, a first matrix circuit for producing a first output signal on a selected output thereof corresponding to a particular on-time set in the on-time setting unit; an off-time setting unit, independent of the on-time setting unit, for selectively setting off-times; a second matrix circuit, independent of the first matrix circuit, for producing a second o...

A pulse switch capable of producing a large number of pulses for its reduced size. The pulse switch has a rotatable shaft, a gear having peripheral teeth and provided with a hub portion, the gear being adapted to rotate as a unit with the shaft, an operation member provided at its end with an integral cam portion for engagement with the valleys of teeth of the gear and disposed to loosely fit the hub portion of the gear, and a switch having a center resetting mechanism. The center resetting mech...

A pulse laser has a laser resonator, a laser medium in the laser resonator, and a deflecting device. The laser medium emits an emission light. The deflecting device switches an optical path of the emission light to output the emission light as a laser pulse. The deflecting device includes a deflecting member and a pumping device. The deflecting member is arranged in the optical path of the emission light. The deflection member has a refractive index which changes based on a pumping light inciden...

A pulse thruster delivering electrically charged fuel attracted to a plate having an opposite charge where such fuel is ignited, causing an impulse force which process is repeated.

The present invention provides a simply constructed, improved pulse combustor realizing stable pulse combustion with less noise and vibration. The pulse combustor includes: a combustion chamber; a mixing chamber coupled with the intake side of the combustion chamber via an opening provided with a flame trap; a gas supply conduit connecting to the mixing chamber for supplying fuel gas; and an air duct connecting to the mixing chamber for supplying air. The total volume of the mixing chamber, the ...

A pulse processor for use in a scintillation counter for converting detected scintillations to coded digital signals. The pulse processor includes means for receiving detected scintillations, a delay member coupled to the means, and bistable means coupled to both the means and the delay member for generating coded digital signals responsive to the detected scintillations. The width of the digital signals is proportional to the height of the detected scintillations.
