Title: Wire coil former for wire mill
Inventor: SCHENKE ROLF
IPC: B21C47/10
Filed: 1996-05-22
Abstract: The coil is formed by an upright hollow cylinder (7) which is moved continuously or intermittently in three directions by linear cylinder and piston drives (8) during coil forming (1). The drives thrust off a fixed frame (9) and engage the cylinder at an offset so that the cylinder endface facing the coiling shaft (3) sweeps over the entire circular surface defined by the outer and inner diameters of the wire coil being formed. When two drives are used, these should be offset by 90 deg  in the same plane and the cylinder may be suspended in a cardan bearing (11) or on chains or movable rods. The bearings (12) of the respective drives allow these to swivel in space, the drives controlled in terms of frequency, stroke and co-ordination by hand or if automatically, then by a memory circuit.

Title: Strikingly-effective method accelerates wet mixing of e.g. bulk building materials and foundry sand
IPC: B28C7/02
Filed: 1996-08-31
Abstract: The optimising performance of mixers for bulk materials with water addition. These typically prepare concrete, foundry sand or sand-lime compositions in quantity. In the new method, a continuous electrical discharge is produced in the material during mixing, by a high frequency generator. The electrical resistance of the mixture is measured constantly during the entire process. To this end, rod electrodes are immersed in the material. Further wall and base electrodes used, are insulated from the mixer casing. Analogue resistance values are measured and converted into digital form. The results are displayed and recorded as a graph of resistances against time, using a personal computer. This is compared with standard curves stored in the computer.  Also claimed is a system to carry out the optimisation.
