Abstract: L'addition de quantites mesurees d'Al2O3 dans de la poudre de Si3N4 a haute purete (contenant moins de 0,1% en poids de cations d'impuretes et contenant Y2O3 en tant qu'additif de densification) permet d'ecourter les temps de frittage pour obtenir des corps de Si3N4 polycristallin ayant des densites approchant la densite theorique, et un traitement thermique de cristallisation apres frittage permet d'obtenir des resistances a temperature elevee qui ne pourraient etre obtenues en presence d'Al2O3. Les corps en Si3N4 obtenus sont utiles pour la fabrication de pieces et composants de moteurs ou pour des regenerateurs ou recuperateurs de chaleur perdue. De plus, de tels corps en Si3N4 possedent une bonne resistance a l'oxydation.

Abstract: A tube expander (10) for extrudably deforming tubes (12) into conformity with a flange (16) has a plurality of first and second forming members (28, 30) circumferentially arranged an a mandrel (20). In an initial position, the forming members (28, 30) are axially offset and radially retracted for ease of insertion into the bore (13) of the tube (12). After insertion, the mandrel (20) is partially withdrawn by an actuator and by such action, the forming members (28, 30) are brought together in an abutting, axially aligned, and radially expanded relationship such that workpiece-contacting surfaces (40, 42) of the forming members (28, 30) are brought into substantially continuous circumferential contact with the tube bore (13). The workpiece-contacting surfaces (40, 42) are maintained in continuous circumferential contact with the tube bore (13) as the forming members (28, 30) and the mandrel (20) are withdrawn from the tube end, thereby uniformly extruding thetube.

Abstract: The invention relates to a device that detects overcurrents and the loss of one or two phases occurring suddenly in the supply line 2 of electrically operated means M. In both cases the aforementioned detection is followed by the said means being disconnected from the electricity mains. 
     The phase loss is detected when, in one or two phases of the line 2, the current la, Ib, Ic therein is below, for a predetermined period of time, an established value. 
     The overcurrent detection takes place when a line current exceeds, for a predetermined period of time, a threshold value Is. In one form of embodiment, the device trips immediately; in another it operates with a time lag that is a function of the ratio K between the line overcurrent and the threshold value Is, and it again becomes non-operative when the overcurrent ceases, as a function of the said ratio K.

IPC: B65H51/16
Filed: 1980-09-09
Abstract: The invention provides an injector having a suitably formed head which can partially penetrate through a lateral aperture in a spindle into the vicinity of a chamber containing an expansible capsule. Penetrating into the chamber, the injector laterally displaces the capsule and by injecting through a beak a fluid under pressure creates in the axial passage a negative-positive pressure necessary for transporting the filament. In the vicinity of the chamber there can advantageously be provided a mobile section which is circumferentially displaceable by a projection which is included on the head of the injector, when the injector penetrates or is penetrating the spindle. The injector is further provided with an arm which may be pivoted in the vicinity of the balloon container or on an auxiliary bench.

Abstract: Magnesium is recovered from a superheated gaseous mixture comprising essentially carbon monoxide gas and magnesium vapor by shock-cooling the vaporous composition with a spray of liquid magnesium preferably heated to a temperature near its vaporization temperature, that is to a temperature between about 800 and 1100°C. The liquid magnesium is instantly vaporized with a large absorption of high temperature heat and the vaporous mixture is thereby cooled to a temperature to below about the vaporization temperature of magnesium that is to below about 1500 °C. The resultant vaporous magnesium is recovered by condensation to produce a molten magnesium product.

Inventor: DI MARTINI CARL R
IPC: C22B30/02
Filed: 1981-03-20
Abstract: Antimony values are separated from a material containing a sulfo-antimony compound of copper, e.g. tetrahedrite ore concentrate, by a process involving establishing a pool of molten lead, adding a metallic alkali metal, e.g. metallic sodium, to the molten lead in an amount which is sufficient to reduce the combined antimony of the sulfo-antimony compound or compounds of copper of the tetrahedrite to metallic antimony, adding the tetrahedrite ore concentrate to the molten lead, and mixing together the alkali metal, molten lead, and tetrahedrite ore concentrate. The alkali metal and sulfo-antimony compound of copper are reacted together in the presence of the molten lead for a period which is sufficient to reduce the antimony of the sulfo-antimony compound of copper to metallic antimony and to form one or more sulfo-alkali metal compounds of copper, and a matte phase which separates from the molten lead. The reduced, metallic antimony passes into the molten lead pool, and the sulfo-alkali metal compound or compounds of copper report in the matte phase on the surface of the molten lead pool. The matte phase is separated from the molten lead. The metallic antimony is then recovered from the lead. Alternatively, if lead- and antimony-containing alloy is desired as a product, the antimony is retained in the lead, and additional antimony and/or lead may or may not be incorporated into the alloy, as desired or required, to obtain the desired alloy composition. Should the alloy product be a desired product, the starting lead of the molten pool will ordinarily not be a liquated, rough drossed lead bullion, but instead another lead such as, for example pure lead or antimonial lead. The process herein is a relatively low temperature process employing temperatures of the molten lead pool above the melting point of lead but ordinarily not in excess of 650 DEG  C. Further, the instant process does not require a smelting furnace but is ordinarily carried out in a kettle.

Abstract: The invention is concerned mainly with chemical analysis tests in which small plastics bodies (16), such as spheres, have an adsorbed coating of reagent which reacts with a component of a solution in which the spheres are immersed. 
     A problem with such analysis methods is that a large number of tests must be made without any confusion as to what spheres have been immersed in a given solution. 
     A support means holding and identifying a plurality of spheres comprises a plate (10) having an array of holes (12) therein; and accessible through each hole a cage-like structure (14), of helical or basket form (104), in each of which a sphere (16) is supported with minimal contact, so that maximum access of solution to the spheres is provided on immersion, and optimum draining on removal of the spheres from a solution. 
     An important use is in bio-chemical and medical assay tests, for example, in screening of large numbers of diabetes suspects through blood tests.

Abstract: A natural orange juice concentrate prepared from natural orange compounds is disclosed. The orange juice concentrate has at least 35% solids including pulp, non-volatile compounds, pectin and volatile compounds. This orange juice concentrate has at least 65% of the aroma and flavor volatile compounds of the natural juice. The aroma and flavor volatile compounds comprise a low boiling fraction and a higher boiling fraction in a ratio of at least 4:1. The ethyl butyrate level is at least .1% of the total volatile compounds, the proportion of ethyl butyrate to limonene being in the range of .0015:1 to about 0.6:1. 
     The orange juice concentrate is prepared by separating natural orange juice into a pulp portion and a serum portion. The serum portion which comprises 7% to 20% solids and from 80% to 93% water is concentrated by removing essentially pure water. The concentration step can be accomplished by freeze concentration or by sublimation concentration. When sublimation concentration is used, the pulp does not have to be separated from the serum. Substantially 100% of the non-volatile solids are retained. Moreover, the product is substantially free of oxidative degradation products.
