Title: Loop forming on helical springs
IPC: B21F35/00
Filed: 1969-09-25
Abstract: Method for forming loops at the end of helical springs in which a spring is so held by a retaining device that part of the spring stands away from the retaining device. A first tool moves across the direction of the retaining device to loosen a loop and bend away from the rest of the spring, and a second tool moves towards the first tool, moved across the retaining device to grip the spring wire and press it between the first and the second tool so as to permanently shape the wire and to keep the loop in the required position. The first tool comprises a first and second part which can move along parallel paths transversely to the retaining device and the first part is first moved transversely to the retaining device to separate the windings of the protruding part from the rest of the springs and form a loop, moving the second part across to the retaining device to grip the loop and bend it further, after which the second part holds the loop in its position, so that by means of the second tool it can be gripped after which the second tool is moved towards the second part to press the spring and shape it permanently. Device permits forming of good quality loops without exchanging tools at the ends of different types of springs, including left and right winding spirals.

Title: Energy storage, distribution and production system - stores water from power stations in underground lakes
Inventor: DENIS LOUIS H D
IPC: F03G7/04
Filed: 1974-05-07
Abstract: Power generators may work at a constant rate, i.e. coal, oil fired or nuclear power stations, hence improving the overall efficiency, by the storage, during low energy demand periods, of heated water in large underground natural lakes.
