Furnace Draw

[Rene]

Here are some ways of removing barrels from the top of an up-pipe

    nakakuk

The normal Dozer Draw (top-left) is of course very well known. It draws a barrel every 4th tick. If you stall the input at the bottom of the pipe, you can pace the production of barrels quite easily.
A variation of the Dozer Draw is useful when the barrel has to be carried away somewhere (mid-top)

The normal Furnace Draw (bottom-left - name tossed by JF) can handle a higher pace than Dozer Draw. It draws a barrel every 2nd tick. This has been quite useful in a number of solutions already, I am not sure who the inventor is. It does not work in the old physics model.

The Half Furnace Draw (mid-bottom) draws a barrel every 2nd tick, and burns the others. It may be useful in some solutions (like in junufel). In the old physics model it is more useful, there it draws all barrels, and I think I have seen it once in an old solution.

Most useful is the Double Furnace Draw (bottom-right - new invention). It draws a barrel every tick, and can therefore handle a constant stream of barrels. It works in both physics models.

Top-right is a funny variation that may be useful sometimes.

Of course, you can also draw from a pipe by using a packer or un-packer (not shown in nakakuk). It draws a barrel every 2nd tick (every tick in the old physics model) and can only deliver them to the right side, but can be used to regulate when to draw, and when not.

I think I first saw it in Hand-E-Food's solution to Stuck: laxudys.  I started using it everywhere I could after that.

Now that is just cool!  I didn't think there was ever going to be a way of going up a pipe at full speed.

Here's a dozer setup that draws every other tick.  I call it the "Triple Dozer Draw".  The version on the left is more compact but messes up the crates' order; the version on the right keeps the cargo in the correct order; it has a longer pipe feed-in and a delay device on the end.

EDIT:And by using two parallel up-pipes, one can do a full-speed draw.

Well, talk about parallel invention. I just came up with a very similar dozer draw in my solution to Hand-E-Food's Traffic Warden (lumydeb) It draws every 2nd cycle, but spreads the barrels evenly to the left and right, which came in very handy in that solution. Didn't think about a way to make it move all to one side, though.

By the way, any reason you call it "Triple Dozer Draw", when there are 6 dozers in it?

Because there are three up-pipes that get drawn off of, so it's a Triple Draw, using Dozers.

I made bucky's triple dozer draw (the one that screws up the order) keep the order without making it larger dodagen
