Title: Wire recovery from used tyres - uses deep cooling and hammering to liberate wire for size sorting
Inventor: HELDT RUEDIGER
IPC: E04C5/01
Filed: 1989-07-20
Abstract: A process for recovery of wire from tyres has car or  truck tyres cut into pieces according to wire length required or whole, cooled to -70 deg.C, or less and hammered.

Title: Napping machine monitor -  uses combination of mechanical pile thickness measurement and optical measurement of pile density
Inventor: VOSWINCKEL GERHARD
IPC: D06H3/00
Filed: 1990-09-07
Abstract: To determine the effectiveness of a napping machine, the pile (3) formed on the fabric (4) is measured by a combination of mechanical monitoring of the pile thickness and optical monitoring of the pile height and the pile density. The measurements are used directly to regulate the operation of the napping machine. The pile density is determined by a light beam (14) aligned at a tangent to the ground fabric (13) while it passes around a deflection edge (12) to open out the pile (3). The light beam (14) is moved to and fro between a position (ho) directly at the ground fabric (13) and a position (h) outside the pile. The pile thickness is measured by a roller pressed against the fabric (4) with a defined pressure through a path setter for the roller axis. ADVANTAGE - The method gives an objective measurement of the napping action, automatically, to give readings unaffected by subjective judgements.
