Abstract: A process for controlling the brightness (dimming) of a gas-discharge lamp (GE) which is located in a series resonant circuit (L1, C1) connected to a rectifier-inverter combination (10, 20), by varying the frequency (f) and the duty ratio (D, d) of the output alternating variable (uw) generated by the inverter and supplied to the gas-discharge lamp and to the series-resonant circuit (X; L1, C1, GE). The lamp (GE) is operated in a frequency range in which the dependency of the lamp power (Pab) on the frequency (f) of the output alternating variable (uw) can be represented by the duty ratio (D, d) as a parameter as a family of characteristic curves (K1, K2, K3, ...), each of which runs in the manner of a bell-shaped curve starting from a maximum value and reducing to form a point of inversion. The maximum value of the individual characteristic curves (K1, K2, K3, ...) of the family becomes smaller as the duty ratio (d1, d2, d3, ...) associated with these characteristic curves (K1, K2, K3, ...) as a parameter becomes smaller. The process is intended to be designed such that the brightness of a gas-discharge lamp can be varied in a stable manner without flicker. This is achieved in that the frequency (f) and the duty ratio (D, d) are in each case selected such that the operating point (B1, B2, B3, ...), with at least two characteristic curves selected or available for a specific lamp power (Pab), in each case coming to rest on that characteristic curve which has the lower gradient at this lamp power (brightness). <IMAGE>

Abstract: A ceramic material for making ceramic moulds and core for metal casting is described comprising basically granular or bubble refractory material, eg. alumina or mullite, bound together by hardened ceramic slurry. Moulds for lost wax casting are built-up by dipping a wax pattern in ceramic slurry and then applying granules of bubble alumina in an all over coating. A plurality of such coats may be applied by allowing the slurry to harden between applications. The moulds are more insulating than those using tubular alumina grits, for example, and produce castings with smoother surface finishes.

Abstract: Afin de produire une planche d'impression flexographique en relief, on utilise un nouvel élément photosensible d'enregistrement qui comprend un support indéformable (A), une couche d'enregistrement (B) photopolymérisable de formation du relief, qui peut être composée d'au moins deux couches individuelles (B), et une couche de couverture (C) optiquement transparente qui adhère fermement à la surface de (B). Lorsque l'on expose à de la lumière actinique sous forme d'image la couche d'enregistrement (B) photopolymérisable de formation du relief faisant partie du nouvel élément photosensible d'enregistrement, la solubilité des zones éclairées se différencie de la solubilité des zones non éclairées, de sorte que les zones non éclairées peuvent être enlevées avec un solvant (développées). Par contre, la couche de couverture (C) optiquement transparente du nouvel élément photosensible d'enregistrement n'est ni soluble ni gonflable dans le solvant en question. Le nouvel élément photosensible d'enregistrement exposé à une image peut toutefois être développé en une seule opération au moyen d'une émulsion du type "eau dans l'huile" ou "huile dans l'eau". Ces émulsions sont également appropriées pour développer des éléments d'enregistrement photosensibles exposés à une image dont les couches d'enregistrement (B) photopolymérisables de formation du relief se composent d'au moins deux couches individuelles (B) ayant des solubilités différentes. Le développement se fait dans ce cas également en une seule opération.
