Abstract: A process for improving the flame retardancy, hygroscopic, soil release and other properties of a polymer substrate is provided in which the substrate is contacted with a suitable aqueous mixture containing a water-soluble monomer and an organic halogen-containing hydrophobic carrier compound at a temperature of between about 40°C to 100°C. Polymerization of the monomer is thereafter initiated by a chemical or physical initiator to form a polymer evenly disposed on the substrate. The flame retardancy, hygroscopic, soil release and other surface properties of the substrate are thereby improved. The mixture may be in the form of an emulsion wherein the hydrophobic carrier compound is emulsified by an appropriate agent. The invention also pertains to the improved substrates prepared in accordance with the present process.

Abstract: Frames of vectors of digital speech samples are buffered (11) and each frame analysed to provide gain (G), pitch filtering (QP,QPP), linear-predictive coefficient filtering (QLPC) and perceptual weighting filter (W) parameters. Fixed vectors are stored in a VQ codebook (13). Zero-state response vectors are computed from the fixed vectors and stored in codebook (14) with the same index as the fixed vectors. Each input vector (s n ) is encoded by determining the index of the vector in codebook (13) corresponding to the vector in codebook (14) which best matches a zero-state response vector (v n ) obtained from the input vector (s n ) and the index is transmitted together with side information representing the parameters. The index also excites LPC synthesis filter (15) and pitch prediction filter (16) to produce a pitch prediction (ŝ n ) of the next speech vector. A receiver has a similar VQ codebook and decodes the side information to control similar LPC synthesis and pitch prediction filters to recover the speech after adaptive post-filtering.

Abstract: Lithium feed to an aluminium-lithium alloy production system is achieved at a highly controlled rate by advancing a plunger (25) at a predetermined volumetric rate into a body of molten lithium retained in a holding vessel (20) to displace the lithium toward an overflow port (33) through which it is fed into a mixing vessel (67) where it is combined with the molten aluminium. Control of the aluminium feed rate is achieved by maintaining a constant head height upstream of an orifice (68). The thus metered streams of molten lithium and aluminium are then combined in a vortex bowl, whose outlet then feeds the molten alloy to a casting station.
