Abstract: Analog signals can be fully encoded as an asynchronous time sequence generated by a time encoding machine (TEM). With knowledge of the parameters of the time encoding machine, the asynchronous time sequence can be decoded using a non-linear time decoding machine. In one embodiment, the non-linear time decoding machine generates a set of weighted Dirac delta functions centered in the intervals of the asynchronous time sequence of the time encoding machine output. The weighting of each of the delta functions is determined by the parameters of the TEM as well as the values of the time sequence. The generation of the series of delta functions is a nonlinear operation (500, 510, 520). The input signal can be recovered from the series of weighted delta functions by (530) applying this series through an impulse response filter.

Abstract: The invention relates to a cellulose-based package material having an increased adsorption capacity and a process for its manufacture. According to the invention, the package material is treated in a permanent manner with an aqueous suspension containing a mixture of fulvic acid and humic acid or salts thereof in the wet technological phase (step) of the paper manufacture. The treatment is carried out in the substance or on the surface of the package material during processing. The wet product obtained can subsequently be dried to a paper, paper board, cardboard, corrugated paper or other cellulose-based laminated product.

Abstract: A beet juice treatment method in which reaction products are recycled. Beet juice is first prelimed with lime and CaCO.sub.3 to produce first and second juice fractions. The second fraction contains flocculated materials, and is combined with CO.sub.2. Solid flocs and calcium carbonate reaction products are removed from the second fraction. The second fraction and first fraction are then recombined to produce a third juice fraction which is combined with lime in a main liming stage for additional purification. The third fraction is then supplied with additional CO.sub.2 to generate a CaCO.sub.3 sludge product. The sludge product is divided into first and second portions. The first portion is reused in the preliming stage. The second portion is converted to regenerated lime for reuse in the main liming stage and possibly the preliming stage. These steps reduce waste production and provide economic benefits.

Abstract: A process for the removal of non-sugar impurities from beet diffusion juice having essentially no beet tissue particles therein and comprising water, sugar, and dissolved and colloidal non-sugar impurities. The diffusion juice is subjected to a progressive preliming procedure to thereby produce a limed first juice fraction containing non-sugar flocs and a limed, floc-free second juice fraction. The fractions are separated and the floc-free fraction is subjected to cold and hot main liming. Subsequently, and without substantial mechanical or chemical degradation, at least a portion of the first juice fraction containing at least a portion of the non-sugar flocs is united with the main-limed second juice fraction in a first carbonation procedure wherein carbon dioxide reacts with the lime present to produce calcium carbonate precipitate which, in addition to being an adsorption filter aid, forms protective scales around the floc particles.

Abstract: A cellulosic starting material, substantially devoid of nitrogen values is moistened to bring its water content to at least 50%, pasteurized by steam treatment during which the temperature is increased to a maximum of about 70.degree. C and maintained at such temperature for about 12 hours during which time a relative humidity of about 100% is likewise maintained whereby the starting material is digested. The material is cooled to about 55.degree. C to proliferate thermophilic metabolite producing microorganisms. This temperature is maintained for about 36 hours and is then lowered to about 40.degree.-45.degree. C and maintained at that level for about 24 hours whereby another group of microorganisms is proliferated. The substrate so produced is cooled to 25.degree. C or less. The process provides the substrate with metabolites that protect it against microorganisms which compete for substrate carbon sources with the macrofungi to be cultivated on the substrate.
