Title: Extrusion and moulding apparatus and method
Inventor: JACK RAYMOND LESLIE
IPC: B29C48/08
Filed: 1995-08-03
Abstract: Polyvinyl alcohol is processed into fibre or pellets for further processing, or directly into water-soluble film, in a screw-and-barrel extruder, which has a slow temperature rise and a mild kneading action achieved by a non-stick coating applied to the screw. Adhesion-reducing surface may be inherent to the material of which the screw is made. The coating may be a fluorocarbon. The screw feeds the material to a die which may too have a non-stick/slippery coating as may the barrel housing the screw. The die may be a spider die with a mandrel over which the product is drawn to form a tubular film or extruded as fibres and chopped into pellets. The application makes references to polyvinylalcohol when processed as above and to non-detection of carbon-carbon double bonds in polyvinylalcohol fibres using <13>C n.m.r.

Title: Adaptive control method for cyclic signal
Inventor: GOTO KATSUHIRO
IPC: H03H21/00
Filed: 1998-10-20
Abstract: An adaptive control method employs an adaptive signal generation algorithm 11 for generating an adaptive signal y(n) which cancels a cyclic signal f(n) at a measurement point 24, and an adaptive coefficient vector renewing algorithm 12 for renewing the amplitudes a(n) and phases #(n) of the adaptive signal y(n). The adaptive coefficient vector renewing algorithm 12 is quasi-normalized by a sum [A(#)+γ]. The A(#) is again measurement of a transfer characteristic 23, and the y is a divergence prevention constant. Hence, in a frequency region where the gain A(#) is high, a step size is small so that the stability of the adaptive control method can be enhanced. In a frequency region where the gain A(#) is low, the step size is large so that the adaptability can be improved. As a result, the convergence stability and the characteristic following the frequency variation are compatible with each other. The method may be used for active damping of vibration or active noise suppression.
