Gated Pulse Frequency Generator Schematic

Don, got a question about the variable frequency generator. Was it set to a max of 10khz or was it higher? I noticed you said something about 40khz, is that for the variable frequency generator?

Howdy just got in from work ...I have a multism 11 started if someone wants to play with it..The 122 option isnt available with the sim so ive been using the 123.I havent figured out how to get the adjustment section tied into the 123 yet.The part i dont understand is connections M1 and B.
 
I stuck the tecktronix scope on it and tried to measure the frequency... weird .....  hope somebody will check it out.Ehh im probably wrong but it looks like the gate is providing the "hit"  lol  I dont know  but will somebody tell me wer the M1 and B connections come from cawz in this sim I made up a pulse for just the M1  connection.

M1 is from figure 2 of stan meyers control circuits patent its a variable width pulse based on the position of the gas pedal, controlled by a sliding metal shuttle or window between a row of LED's and Photosensors. the 16 inputs to a multiplexor are variable and that translates to a 10% thru 90% pulse width

This pulse width does 2 things, one: it controls the Positive side voltage using figures 3 & 4 to the primary of the VIC coil
and
two: it controls the number of gated PLL signals.

( there is a gate anded with the PLL... fig 6 and fig 7... these then are supervised by figure 2 for final throttle speed or GAS PRODUCTION by using a PWM level to control output

B: is probably used to calibrate the figure 6 for mechanical resonance ( using a 50% duty cycle signal that is fixed from figure 12)  then switched to M1 for running normal operation via throttle pedal control

Mr.Don is it normal to get an output frequency much differant from the input frequency? The sim shows putting in 1khz and outputing 3khz

Tony,I once made the frequency generator on a breadboard,and the 555 output was @ 42khz.I haven't checked to see if Stan used different caps and resistors with this one,but my guess would have been the same for both.
I don't see anything in that circuit that is used to adjustment for a max setting of frequency.The Gated Pulse Frequency Generator (fig 6) just adjust duty cycle,and the Variable Pulse Frequency Generator adjust frequency (fig 12).
 
So if you get 40khz out of the 555,then you get 4khz after the first decade counter,then 400hz,40hz.
 
Newguy,I don't think that the frequency should change after passing through the 74122.As stated above,it's only meant to adjust duty cycle.

Ive got  cleaner sim now but still no adjustment but im still try'n to fix it.

yet a little closer i believe but still no adjustment.Im not familar with the 74123 chips but there must be a reason he chose it.. i say "it" cawz the 74123 is just a double 74122 but the 74123 is all thats available for the sim.The only thing specific ive found about the chip is that its not a 50% duty cycle like a 555 chip.Im still try'n to fix it the sim tho.Wish we had the frequency generator Stan used cawz in his notes he says its a resonate frequency generator.
 
 
anywho I just changed d1 to 1n418 and its behaven a lil differant, still no dern adjustment tho.

Im under the impression this circuit is most important to provide the correct waveform ?
 
well i just changed the d1 to a 1n914 and the frequency to 5khz on the am signal and it looks more like Stans drawings after you let the sim run for a minute and really look at it.Still no adjustment tho and i havent got the cell off or pull ring switches to work.
