The improved Flynn Gap.

[synchro1]

The "Improved Flynn Switch" can turn on and off and can be made to swivel in and out of place. It can snap into position behind a larger pair of keepers and turn on simultaineously. An extra large neo cylinder would be fixed in position between these larger keepers. This would complete a second level switch. This kind of  swivel coupling would eliminate the larger neo field effect from linking up with the one behind it through the smaller switch keeper. This would increase the repulsion force by NINE TIMES on the magnet piston.

Robert Murry Smith reports his magnets are 1/2cm in diameter, x 2cm,in length, one alnico one neo.: One hundred feet of 24 gauge wire and two steel keepers. He goes on to say a 20ufd 12v capacitor can deliver the pulse! I plan to use these materials for the base of the two tier swivel coupling.

Here's what a 12 volt 20 microfarad capacitor looks like:

                                                                             "SYNCHRO SWITCH".

Eureka! I just invented a very simple and super efficient power switch. In place of the alnico magnet I laterally positioned a 12 volt relay. The steel keepers have a ceramic magnet across the top. The steel keepers have a small permanent field now due to the magnetic circuit through the relay core when it's off.

When the relay's charged., the keeper field is amplified beyond the strength of the electromagnetic relay coil and magnet alone. When the relay current's reversed, the magnetic field drops dead altogether. Perfect for an iron rotor! The relay charges as the iron rotor approachs, magnifing the attraction field, then the current's reversed in the relay and the iron rotor's free to cleanly slip by. Two brief reversed pulses. I'm calling this the "Synchro Switch"! The swicth allows for three power settings. Power on positive; Maximum attraction. Power off; Partial attraction. Power reversed; Zero attraction! Perfect all magnetic motor power coil for an iron rotor!

Those are tantalum caps, I believe. Be careful with those, they explode very nicely when overvolted sufficiently.

                                                  Current reversal kills Tantalum capacitors.  Good reason to avoid them!

The keepers and magnet strength of the "Relay Flynn Switch" determine the off position remnance. It can be eliminated entirely. The redirected relay flux can turn off additional attraction too, but too much magnet strength overpowers it.

This design would make a cool little "Scrap Yard Magnet" toy for a child with a battery and DPDT switch, suspended from a miniature crane and winch. A large scale up could spin a two axe head rotor, with two large magnet switches driving it.

Two batteries can run this kind of circuit through a commutator. One battery's reversed. Four relay power switchs could fire off the same connector strip and reverse current the same way through another strip from the turned around battery. Eight power switchs would only require wires to the commutator, not eight seperate costly DPDT reed switchs.
