One of our best known contributors used an avatar showing such a device, which I believe he had seen being used on an experimental project.(I cannot locate said avatar now, so perhaps it has been altered). I have now found, by chance, three US patents using the device. It had the virtue of compactness for stacked items, and also was very "draggy", due to air-flow between the layers. It also could be used to revolve an arming feature, due to its helical form. The three US patents are US 3710715, US 3792662 & US 3891162, and form a particularly neat use of this device. If anyone has problems accessing these, let me know, and I will explain how they can be found on "google advanced patents", espacenet or USPTO.
Does anyone know if such a "tail" was ever used? Thanks.
Martin.
