Abstract: An adaptive filter suitable for speech analysis which is constructable on a silicon chip. The filter has a single multiplier (26) and a single adder (27) in series together with appropriate registers or memories (28, 29, 30) so that the output of the adder is either looped back to the adder itself so as to perform the operations of an all-zero digital lathe filter moving average, linear predictive coding, or alternatively is looped, after a delay, to the multiplier. Another register (25) provides the multiplier with the constant values typically associated with lattice filter coefficiency. Preferably the multiplier (26) is an M-Stage pipeline multiplier so as to reduce the area necessary for its incorporation on a silicon chip. The filter accepts digital samples of the voice input (102) and outputs (17) a compressed data representation of the input.

Abstract: This invention relates to a method of manufacturing integral melt conveying nozzle probes for injection molding. The generic term nozzle probe is used herein to include both nozzles through which the melt flows centrally and probes which it flows along the outside of. The method includes forming a stainless steel outer member to receive an electrical heater member therein with a longitudinal space therein. A long thin thermocouple sleeve having a closed forward end is located in the space, which is then sealed against leakage by applying a nickel brazing paste to the joints and brazing them in a vacuum furnace. Copper is then cast into the space in a vacuum furnace to provide a metallurgical bond between the highly conductive copper and the heating element, the thermocouple sleeve and the other parts of the nozzle probe. After casting, a long thin drill is inserted into the sleeve to drill through the closed forward end and a predetermined distance into the copper. The use of the sleeve avoids the problem of the drill wondering slightly off line and ruining the whole unit. A thermocouple can be removably inserted into the bore with its head precisely located in the highly conductive material adjacent the forward end of the nozzle probe to provide an accurate and reliable measurement of temperature in this critical area.

Abstract: This invention provides a process for stabilising a population of a mutant micro-organism in a bioconversion system whereby growth of revertant cells is suppressed. 
     The process involves limiting a nutrient which is essential for cell growth so that the cells selectively grow on a growth carbon source rather than on a non-growth carbon source which is present. The revertant cells being suppressed have a similar ability as the parent strain of the mutant micro-organism to grow on the non-growth carbon source in the bioconversion system. 
     The non-growth carbon source in the bioconversion system is metabolised to an extracellular accumulating quantity of a desired metabolite, e.g., toluene is converted to muconic acid.
