Abstract: The application relates to a method of and device for forming areas having modified optical properties in a layer (3). The layer (3) is heated locally up to a temperature above the write temperature by scanning said layer with a radiation beam (7, 107a) whose power (P) is adjusted in accordance with a pulsating pattern (Fig. 4a). A forming-speed signal (α(t)), which is indicative of the speed with which the areas are formed, is derived from the radiation reflected from the layer (3) by means of a measurement circuit (50), comprised by an adjustment circuit (12). The adjustment circuit (12) further comprises a circuit (61) which adapts an adjustment signal value (Ih) for adjusting the write power depending upon the forming-speed signal (α(t)). This substantially reduces the influence of changing recording conditions on the dimensions of the recorded areas having modified optical properties.

Abstract: A process for producing and purifying lactic acid comprises growing a lactate salt-producing microorganism on an inexpensive substrate containing carbohydrate, corn steep liquor and corn oil until most of the carbohydrate is converted to lactate. The fermentation broth is then electrodialyzed to recover and concentrate the lactate salt in an aqueous stream which is subjected to water-­splitting electrodialysis to form base and a lactic acid product. The resulting lactic acid product is treated first with a strongly acidic ion exchanger in the acid form to remove any sodium or other cations and then treated with a weakly basic ion exchanger in the free base form to remove any sulfate ions or sulfuric acid and to obtain a highly purified lactic acid product.

Abstract: A circuit particularly useful in AGC systems, produces an output current (I OUT ) which is proportional to the difference between a signal voltage (V AGC ) and a reference voltage (V R ) which is practically independent of temperature, by being a function of a ratio among actual values of integrated resistances and of a ratio among substantially temperature-stable voltages. The effects of temperature dependent value of integrated resistances and of temperature-dependent electrical characteristics of integrated semiconductor devices are compensated in order to produce the desired temperature-independent output current which may usefully be utilized for implementing an automatic gain control.

Abstract: Dans la production de portions de crème glacée du type ''ice-cream'' extrudées on a coutume de couper les portions dans une chaîne extrudée de crème glacée, une fois que la chaîne, placée sur une bande transporteuse a atteint un état congelé moyen, après quoi les portions sont transférées sur un transporteur se déplaçant plus rapidement, sur lequel elles sont acheminées à travers une zone de congélation à l'état dur avec entre elles un espacement désiré. La présente invention permet d'obtenir plusieurs avantages, en prévoyant que la chaîne extrudée (6) avance non sectionnée à travers une zone de congélation en continu, avec seulement des étranglements ou des encoches (12) pratiqués dans la chaîne par des outils à déplacement transversal (8, 20, 22), pendant que la crème glacée se trouve toujours dans un état façonnable. Après la congélation à l'état dur de la chaîne, chaque portion (P) est séparée de la chaîne par une simple force de rupture appliquée successivement sur l'extrémité frontale de la chaîne, et on peut obtenir la distance désirée entre les portions en les laissant tomber sur un transporteur (18) se déplaçant à une vitesse accrue.

Abstract: Les points de croisement zéro d'une forme d'onde (v) de tension c.a. appliquée à un fil thermosensible (1) et d'une forme d'onde (i) de courant c.a. conduite à l'intérieur du fil thermosensible (1) sont détectés par une unité de détection de tension zéro (3) et par une unité de détection de courant zéro (4), et l'intervalle compris entre les points de croisement zéro de la tension et du courant est mesuré par une unité de mesure (7). L'intervalle ainsi mesuré correspond à l'ange de phase (PHI) compris entre la forme d'onde de tension et la forme d'onde de courant, et l'angle de phase (PHI) dépend de la résistance (rho) et de la permittivité ((epsilon) spécifiques du fil thermosensible (1). Cette relation est utilisée pour mesurer la température. La relation entre l'angle de phase (PHI) et la résistance (rho) et la permittivité (epsilon) spécifiques est indépendante des dimensions du fil thermosensible. Par conséquent, la température peut être mesurée avec précision, même lorsque le fil est fabriqué à base d'un matériau qui n'est pas suffisamment rigide pour maintenir ses dimensions constantes.

Abstract: Il serait souhaitable de remplacer les solutions à base d'acide nitrique pour le traitement de surface des aciers et autres matériaux semblables par une solution à base d'acide sulfurique contenant du péroxyde d'hydrogène. Toutefois, ces solutions de recharge perdent rapidement leur teneur en péroxyde d'hydrogène, surtout du fait de la décomposition ferrique. Une solution de traitement de surface à base d'acide sulfurique et de péroxyde d'hydrogène possédant une meilleure stabilité, contient une quantité efficace d'un mélange d'acide hydrofluorique, d'acide hydroxybenzoïque et d'un N-alkoxyphényle-acétamide. L'acide hydroxybenzoïque sera de préférence un acide para-hydroxybenzoïque et le N-alkoxyphényle-acétamide sera un N-(4-éthoxyphényle)-acétamide. Il est préférable d'employer une solution saturée de chacun des deux derniers composants, ce que l'on peut obtenir simplement et commodément en ajoutant les composants solides sous forme de bloc(s) qui conservent la solution saturée plus longtemps.

Abstract: Activated carbon is used in gas-mask canisters for filtering air to remove toxic vapours. For military use, the charcoal is impregnated with inorganic salts or organic compounds for improving the chemical activity of the charcoal with respect to toxic vapours having low boiling points and small molecular sizes, e.g. cyanogen chloride. One such compound, namely triethylenediamine (TEDA) has been added to charcoal by sublimation at atmospheric pressure. A more effective method of impregnating charcoal with TEDA utilizes reduced pressure 0.13 to 13 Pa, preferably 1.3 Pa as a driving force to facilitate vaporization of the TEDA by sublimation. The activated carbon to be impregnated is dried at 110°C to 160°C for three hours and transferred to a vacuum desiccator. The required amount of the amine, namely 1.57 to 12.57%, preferably 4.7% is placed in the container on top of the activated carbon and the container is evacuated to a pressure of about 1.3 Pa and heated at 40°C for two to three days until the amine compound is no longer visible on the carbon. The resulting TEDA impregnated carbon provides improved protection against toxic gases compared to the precursor charcoal.
