Abstract: Du carbonate de sodium de dihydroxyaluminium est prepare en faisant reagir un sel d'aluminium ionique avec un exces stoechiometrique de carbonate de sodium dans un milieu aqueux en presence d'hydroxyde de sodium avec un pH compris entre 7,2 et 10,5. Une quantite de carbonate de sodium egale a dix fois au moins, et de preference quinze fois, en poids celle du sel d'aluminium est utilisee et/ou un sous-produit du sel de sodium, mais non du carbonate de sodium, est precipite du milieu aqueux. De preference, le sel de sodium est precipite par saturation du milieu aqueux avec du carbonate de sodium et un sous-produit du sel de sodium avec une concentration en carbonate de sodium inferieure a la concentration invariante pour le carbonate de sodium et par consequent avec une concentration en sous-produit du sel de sodium superieure a la concentration invariante pour le sous-produit du sel de sodium. Apres separation du sous-produit de sel de sodium, le milieu aqueux contenant du carbonate de sodium est reutilise comme source de carbonate de sodium pour une reaction ulterieure avec un sel d'aluminium.

Abstract: Thermostat ayant un corps sensible a la chaleur (5) en materiau ferromagnetique et un aimant mobile (4) cooperant avec celui-ci. Une paire de contacts (6, 7) sont fermes ou ouverts en fonction de la position de l'aimant, cette position dependant a son tour des proprietes magnetiques dependant de la temperature du corps sensible a la chaleur. L'aimant (4) est expose a une force contraire qui est opposee a la force d'attraction, et la force d'un ressort s'erxercant sur la paire de contacts effectue une action de fermeture des contacts dans une position de l'aimant et une action d'ouverture des contacts dans une autre position de l'aimant. Plus particulierement, la force de renvoi et la force du ressort sont exercees par un seul et meme ressort qui agit entre le contact mobile forme par une languette de contact et l'aimant.

Abstract: A system for testing a wave guide arc detecting circuit (18) for a microwave system is disclosed. Testing is accomplished by utilizing a pulsed laser source (32) to generate pulses of optical energy which are used to simulate an electrical arc across the wave guide (16). The laser source (32) is then positioned such that the pulsed output signal impinges upon the wave guide arc detector circuit (18) to be tested. This is most advantageously accomplished by affixing the wave guide arc detector circuit (18) to the wave guide (16) in a fashion similar to normal operation. This enables the arc detecting circuit (18) to view the end of the wave guide through the interior of the wave guide (18). The laser source (32) is positioned such that the output pulse of the laser source (32) impinges on the open end of the waveguide (16). The operational status of the wave guide arc detecting circuit (18) is determined by measuring the elapsed time between the generation of the output pulse of the laser and the detection of the pulse by the arc detecting circuit (18) being tested.

Abstract: Alliage a base de cobalt et de nickel, qui se prete particulierement a la preparation de protheses dentaires. Il presente en effet les qualites suffisantes de resistance a la corrosion et a l'usure, est deformable a froid et maintient bien sa couleur, se travaille facilement a l'etat fondu et presente des valeurs de durete equivalentes a celles des alliages a metaux nobles. L'alliage contient, a part les metaux de base, comme composants principaux 10 a 50% en poids de chrome, 0,2 a 4,5% en poids de gallium. Le nouvel alliage peut contenir en outre egalement 0,05 a 0,08% en poids de lanthane, 0,03 a 0,1% en poids de neodymium et 1,0 a 6,0% en poids de molybdene. A cause de son elasticite et a cause de son faible poids specifique, l'alliage sert particulierement dans le domaine des protheses dentaires fixes. L'alliage sert specialement a la preparation de plaques de base, de crochets d'ancrage et de crochets d'attache de protheses amovibles. Comme cet alliage ne contient aucun metal noble, les substances de base s'obtiennent facilement et les prix de revient ne constituent qu'une fraction des frais necessites par les alliages a metaux nobles.

Abstract: A display sign of novel appearance is described in which the display plates (20) are formed of a profiled and rolled sheet material. In addition to the enhancement in appearance, the construction employs plates (20) having significant structural rigidity with the result that the framework (14, 16) supporting the plates (20) and the internal lights (18) need not itself be substantial. Cut-outs (32) are formed in the sheets (20) and mouldings of acrylic material (not shown) are mounted in these cut-outs (32), the mouldings being in a contrasting colour. If the edges of the mouldings remain translucent then a particularly attractive halo effect is obtained around the logo or lettering when back lit.
