Patent EP-0061133-A1 (EP)
Inventor: USHIODA MINORU
IPC: C08L51/00
Filed: 1982-03-17
Abstract: A particulate vinyl chloride polymer having excellent processability and heat stability which comprises porous vinyl chloride polymer particles and alkyl vinyl polymers which are included in the porous particles. The particulate polymer is prepared by impregnating an alkyl vinyl compound in porous particles of a vinyl chloride polymer, polymerizing it, and in the course of the polymerization of the alkyl vinyl compound, adding an alkyl methacrylate to the polymerization system and continuing the polymerization. Since the thus obtained polymer has an improved melt-flowability and heat stability, it can be blended with a large quantity of an inorganic filler and can be molded with good processability.

Inventor: ALLUTO LUIGI
IPC: F25B49/02
Filed: 1982-05-13
Abstract: The present invention relates to a system for controlling the flow of refrigerating fluid on cooling or heating appliances to improve efficiency under all load and room temperature conditions, based on detection and control of the temperature difference at the terminals of the evaporators on the said appliances. The said difference in temperature is detected by two temperature sensors, one at the inlet and the other at the outlet of the evaporator, which send signals to an electronic control circuit that, in turn, controls a flow regulator so as to keep said difference temperature constant. 
     Besides improving efficiency under all operating conditions, the said control system also prevents frosting in the return pipe connecting the evaporator to the compressor. Furthermore, on two-door or combination refrigerators with a single compressor and two evaporators, whether series or parallel connected, the present invention provides for independent operation of the two compartments as well as independent adjustment of the temperatures inside.

Abstract: Ce procédé de traitement d'un liquide, en particulier d'eaux usées, consiste à soumettre ce liquide à une phase de nitrification (N), suivie d'une phase de dénitrification (D), pendant lesquelles on contrôle, resp. on fait varier la teneur en oxygène de ce liquide. Afin d'obtenir, conformément aux exigences, une commande variable du temps réservé à la phase de dénitrification (D), l'on établit par une mesure de la teneur en oxygène des eaux usées la courbe de variation de l'oxygène dans le domaine d'affaiblissement (Ab) de la phase de nitrification (N). Selon l'allure respectivement selon les caractéristiques de cette courbe (S) l'on déduit le laps de temps nécessaire à la phase de dénitrification (D). La phase de dénitrification (D) se poursuit pendant ce laps de temps, pris comme facteur de temps (Z), après que la teneur en oxygène a atteint une valeur de seuil (Sw).

Abstract: For switching or, respectively, distributing broadband communication signals in message switching systems, broadband switching matrix networks having crosspoint circuits realized in an ECL technology and which are formed by controllable multiplexers is provided. The controllable multiplexers are mutually interconnected to form multistage crosspoint pyramids respectively exhibiting an outgoing line and a plurality of incoming lines, whereby the controllable multiplexers of a respective plurality of crosspoint pyramids are combined on a chip module. The chip module may be a master slice module. An additional transfer crosspoint in the form of a 2-bit multiplexer can be provided at the tip of the pyramid at each crosspoint pyramid, the additional transfer crosspoint also being connectible to the pyramid chip of a further crosspoint pyramid in order to therefore introduce a corresponding expansion of the switching matrix network. Moreover, when switching or distributing communication signals in the form of frequency-modulated signals and given non-through connection of such a communication signal to the outgoing terminal of the crosspoint pyramid, an unmodulated carrier can be supplied over such an additional transfer crosspoint in order to therefore counter crosstalk interference. The individual crosspoint pyramids can be driven by appertaining drive registers whereby a clock decoder enables the selection of the respective crosspoint pyramid.

Abstract: Afin d'étendre le service téléphonique par bouton-poussoir aux systèmes téléphoniques non équipés pour répondre aux signaux de composition de numéros à fréquence multiple, il est nécessaire de convertir les numéros composés par bouton-poussoir en des impulsions conventionnelles de composition. Un train d'impulsions se composant d'intervalles d'établissement et d'interruption de contacts représentant le numéro composé est converti électroniquement (107) en des séries correspondantes d'intervalles d'établissement et d'interruptions de contacts sur la ligne téléphonique (102, 103) en commutant en position "MARCHE" et "ARRET" (106, 108-1, 108-2) un transistor d'impulsions (101) qui est en série avec la ligne téléphonique. Afin de maintenir le transistor d'impulsions en position "MARCHE" pendant les intervalles de non composition de numéros et pendant chaque intervalle d'établissement de contact, et afin de ne pas atténuer les signaux vocaux, le transitor d'impulsions est polarisé par une source réglable de courant (105). Le courant nécessaire pour polariser en position "MARCHE" le transistor d'impulsions est en rapport linéaire avec le courant de la ligne téléphonique circulant au travers du chemin émetteur-collecteur de transistor, et variant considérablement d'une station à l'autre. Afin de réduire au minimum le courant nécessaire pour polariser le transistor d'impulsions, un détecteur de courant (104) dérive un signal proportionnel au courant de ligne qui est réinjecté à son tour vers la source de courant (105) afin de réguler le courant de polarisation pour qu'il soit proportionnel au courant de ligne.

Abstract: The invention is based on a flat picture screen, in which electrons from a plasma at the rear are drawn forwards through selected holes in a control disc (3), which is provided with line and column conductors (9 and 10) on the front and back. The electrons then receive energy levels of several kV and finally generate light spots on a fluorescent screen. It is proposed that the control disc (3) be additionally coated on its rear side with a layer (multiple layer 18), which is at most 100 nm thick, is electrically insulating and has a secondary- electron emission coefficient of  delta max </= 3 ( delta max = mean number of secondary electrons which are released from the multiple layer by one impacting primary electron, measured at a primary electron energy at which the emission rate is at its maximum). In a preferred embodiment, the multiple layer (18) is a magnesium oxide film, approximately 20 nm thick and vaporised on in a vacuum. This layer ensures that the electron currents reaching the control matrix are strengthened with low-energetic electrons; the brightness and/or contrast of the display can thus be improved. Main application area: high information-content flat displays, especially for data monitors and televisions. <IMAGE>

Abstract: A new type of glass, for example, for use as TL-envelope glass, which as regards phosphor poisoning and Hg penetration has better properties than the present TL envelope glasses. Phosphor poisoning occurs in particular upon sealing of the electrodes and bending or severing and bridging, respectively, during the manufacture of SL- and PL-lamps. 
     The composition of the glass is derived from a glass composition for use in optical glass fibres which is described in European Patent Application 83 200 958. 
     Phosphor poisoning is controlled by restricting the mobility of sodium ions. This is achieved by choosing the quantities of the alkali metal oxides within certain limits («mixed alkali- effect). 
     Hg penetration is controlled by a large quantity of alkaline earth metal oxides in the glass. 
     The glass according to the invention has a good light transmission. A lamp comprising a lamp envelope manufactured from a glass according to the invention only shows a small decline of the luminous efficiency during operation of the lamp.
