12 times more output than input, dual mechanical oscillation system !

What does angle have to with it? When a weight is allowed to go from a starting position to a lower one, the height difference and mass will determin the energy open to be converted. It can't do any work without immediately having it subtracted in full. Nice in practical applications is that you can get a lateral displacement at no charge at all, but as you know, a longer lever doesn't give more energy. More lever, less angle, same result.

  This is how a pendulum can swing in perpetuality. It's based on children playing in a playground. It has been discussed before in this forum. Certain details were missed.
When a child swings on a swing, they lean back. This shifts the weight on the main fulcrum (B). As such, the swing moves forward. And when it slows or stops, they sit upright and the swing reverses direction. Don't tell this to scientists, they've over looked what children have known. It's a secret  :-D
And when they get their swings moving the way they like, often higher than atributed to the net input of force which is ZERO, some interesting things can be observed.
When they lean back, their arms create 2 points with the main fulcrum, or if a solid line is represented, it pivots. As they swing, they start moving upright, fulcrum A. And when they finish their ascent, they stay upright while swinging backwards. When they stop, they lean back again rising even more on the opposite side unless they go to high, then the chains become slack.
A ratchet type mechanism can move the weight A to it's outward position on the downward swing. And with brown representing flexible lines, the drawing shows how what a child knows might be able to be replicated by adults.
And in mechanics, on the backward swing, the weights A & B will move together (hopefully) and if fulcrum B carries both weights, it is okay.
Initially, on the downward swing, the line for fulcrum A would need to be slack. this would allow for torque or what it is those kids know to work, any way, hopefully work for adults.

  @All,
The basic idea is if you have a weight at  the bottom of a line, like on a swing, if another weight leans back,
it changes the center of gravity and pushes weight B forward. When weight A is lifted, it swings as a part of B.
If it is a little forward, then it helps to push weight B backwards. With something like this, it's start position would be at the top of it's swing in it's backward direction.
By having a tab move into it's holder, weight A can pass it and when it swings down, can be reset.

But doesn't the second cable of the swing have a pull back on the whole system that created a negative effect?

   Alan,
When weights A and B start their downward swing, weight B would be supporting weight A.
This would give them both the same momentum. When fulcrum A starts lifting weight A, weight A will have a shorter path to follow than weight B does. This would cause weight A to be pushing weight B.
As far as pendulums and swings go, weight B does not need to move at the ends of it's pendulum. I showed this as part of the mechanics children use.

edited to add attachment.
edit; it might just be that when fulcrum A starts lifting weight A that weights A and b have the same distance to travel. If so, then the energy developed when weight B is supporting weight A is the extra impetus into the system which would allow it to be a dynamic self perpetuating pendulum. A tribute to their efficiency.
A part of the reason is that weight A would be dropping more than it's own path allows for.
