  • Publication number: 20050190865
    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.

  • Patent number: 5480490
    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.

  • Patent number: 4795494
    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.
