Abstract: A water absorbent latex polymer foam produced by the process of combining a foamed latex polymer product with a water absorbent polymer and drying that blend to form a foamable latex polymer containing a water absorbent polymer is disclosed in this invention. The latex foams produced by this process are of great use, for example, within diapers, sanitary napkins, packaging materials and the like. In particular, the use of water absorbent polymers with particle size less than about 30 microns has been shown to produce particularly effective absorbent latex foams. Furthermore, a water absorbent latex polymer foam produced by the process of combining a foamed latex polymer product with both a water absorbent polymer and chitin and drying that blend to form a foamable latex polymer containing both water absorbent polymer and chitin. The latex foams produced by this process are of great use, for example, with wound or surgical dressings.

Abstract: The present invention concerns a circuit by the aid of which the power (Pin) emitted from the RF power sensor (SK) of a radio telephone is processed to become a detector voltage which is proportional to said power. The circuit comprises a transistor (Q2) acting as an active rectifier, which in the ascending part of the positive half cycle of the power (Pin) charges the capacitor (C3). In the descending part of the power the capacitor starts to discharge at a time constant which is remarkably greater than the cycle length of the power Pin). The transistor is biassed by means of a transistor (Q1) so that it is conductive even on the lowest power levels.

Abstract: A vending apparatus ensures that the delay between a customer's selection of an article, and the dispensation of the selected article, is minimized, preferably to less than a predetermined delay, regardless of the point in a multi-article vending cycle. The reduced selection-dispensation delay is achieved through use of a "memory and learning" feature. The "memory and learning" feature is predicated on a recall and/or analysis of the relative times of occurrence of one or more previous dispensations, so that the apparatus' present position in the multi-article vending cycle is determined. The "memory and learning" feature allows the vending apparatus to anticipate how long the article dispensation mechanism should run after the present dispensation, to strategically poise the mechanism for a subsequent dispensation having an optimum selection-dispensation delay. Also disclosed are systems and methods for ensuring that articles are dispensed at a proper temperature, even after a "sold-out" condition is corrected; and for sounding an alarm if a person jars the vending apparatus in an attempt to improperly jar an article from the vending apparatus.

Abstract: L'invention concerne un procédé de correction d'erreurs dans des données reçues, pendant la transmission d'un rayonnement infrarouge d'un émetteur à un récepteur, sans retransmission de paquets entiers. Ledit procédé comprend les étapes consistant à détecter une erreur dans les données reçues. Le récepteur transmet un signal d'accusé de réception négatif à l'émetteur. L'émetteur transmet un accusé de réception prédéterminé afin d'indiquer au récepteur que ledit signal d'accusé de réception négatif à été reçu. Les données sont ensuite retransmises. Les données sont transmises par modulation des positions d'impulsions (figure 1 et figure 2). Une erreur est détectée soit par détection de deux impulsions dans un cycle, soit par détection d'aucune impulsion dans un cycle. Ledit signal d'accusé de réception négatif consiste à transmettre une impulsion dont la durée est égale à celle de plusieurs positions (figure 5). L'accusé de réception prédéterminé transmis par l'émetteur consiste à transmettre à dessein un cycle contenant une erreur connue.

Abstract: Le système proposé servant à rendre sous forme de vapeur n'importe quel liquide volatile, parmi un très large éventail, se compose d'un réservoir muni d'une extrémité ouverte fermée par un élément imperméable au liquide et perméable à la vapeur. Un rebord entoure l'ouverture du réservoir et l'élément est fixé jusqu'au rebord dans une multiplicité d'endroits différents, chacun d'entre eux définissant une zone respective de l'élément fixé par la liaison et mouillable par le liquide volatil. Ainsi, on peut utiliser un seul système pour fournir n'importe quel matériau volatil, parmi un large éventail, simplement en déterminant la zone de surface à l'intérieur de la liaison à mouiller par le liquide volatil pour obtenir le taux désiré de vapeur libérée pour un matériau volatil choisi et la fixation de cet élément au rebord à un endroit pour définir la zone de mouillage déterminée de l'élément.

Abstract: Fibres used for insulation and absorption purposes can be optimally processed in a dust-free manner by mixing the absorption/insulation material shortly before leaving the injection hose or the spray gun with a special foam and then discharging it as a common mass. In this case, the foam can be produced as such beforehand from water, air and a special foaming agent or from binding agent, if necessary with water and air, with or without the addition of foaming agent, and then added to the fibre material and mixed with this. It is however also possible to combine the production process of the foam with the mixing with the fibres or to influence the foam by adding air. The injection hose (3) and the spray gun (7) have, at the outlet, a double tube (8), into which the foam tube (6) leads and whose inner tube (13) is equipped with sluices (10, 11), it being possible for the outer tube (9) to have bores (14, 15) for supplying air. <IMAGE>

Abstract: Method of speech coding which uses a model of production of the word by passing an excitation signal Ck, representing the vocal source and subjected to amplification G, through a long term predictor filter of transfer function 1/B(z) where B(z)=1-bz<-T>, and through a short term predictor filter of transfer function 1/A(z)= SIGMA aiz<i> representing the contribution of the vocal duct. Each frame is represented by values of the parameters Ck, G, ai, T and b. An error signal is generated by subtracting, from the frame of the original word signal, two terms. The said word signal frame is, after subtraction, subjected to short-term analysis filtering and to a perceptual weighted synthesis filtering H, the first term being representative of the output of the predictor in the long term with the time offset T, subjected to the synthesis filtering, while the second term is representative of each of the excitation signals in its turn. Each signal is subjected in advance to amplification G and to the same weighted synthesis filtering as the frame of the word signal. In the course of the same sequence an optimum of the shift T is determined by looking for a perceptual error minimum and the coefficient k is deduced from it, then the optimal values of b and of G are calculated. <IMAGE>
