Abstract: To recover chromium and, optionally other metals, from scrap of complex alloys such as superalloys, the scrap is sulphided to provide a molten matte which is cooled and fragmented. The fragments are slurried in an aqueous solution maintained at an elevated temperature and are agitated whilst being leached with chlorine which is introduced into the solution at such a rate that its redox potential remains below 600 mV. The major portion of the chromium remains in the leach residue whilst other metals present go into solution as chlorides.

Abstract: A pattern (22) of transparent conductive material, such as tin oxide, is formed on a transparent vitreous substrate (10) using a polycrystalline material (12) such as cadmium or zinc sulfide, to mask the substrate surface while depositing material forming the transparent conductive layer, The polycrystalline material and any overlying transparent conductive material are easily removed by a chemical etch, leaving the desired pattern of transparent conductive material (22) adhering to the substrate. Two electrically conductive patterns (32, 37; Fig. 6) may be formed in intersecting relationship and isolated, one from the other. The degree of electrical connection between the two patterns will be a function of the resistance of the polycrystalline material (38) therebetween at points of crossing. In some instances, electro-luminenscence may be obtained by selecting the proper crystalline material wherein an electrical display may be created by selectively energising crossing electrical conductors.

Abstract: Anaerobically-curing compositions are described comprising (A) a polymerizable monomer; (B) a halogen-containing compound as a first initiator component; (C) an amine, organic sulfimide or perfluoroalkyl sulfonanilide as a second initiator component; and (D) an inhibitor of free-radical polymerization. These compositions are particularly suitable as adhesives and may be formulated as thread- locking adhesives or may be modified by the addition of various modifying polymers to obtain desired properties such as increased viscosities or pressure-sensitive properties. Since the compositions of the present invention contain no peroxides or hydroperoxides, they may be stored for extended periods of time without the fear of initiator decomposition and may be manufactured without possibility of explosion.

Abstract: Un melange sous pression d'au moins deux fluides de densites differentes est introduit au travers d'une connexion (1) dans une premiere extremite (2) d'un conduit de separation (3). Lorsque le melange entre dans le chemin d'ecoulement courbe (7) du conduit (3), une force centrifuge initiale produite par le faible changement de direction defini par la grand rayon de courbure (8) initial, agit sur le melange en ecoulement provoquant l'impact des particules et des grandes gouttelettes de fluide plus dense (42) contre la surface interne (41) du conduit (3). Le fluide (42) plus dense separe s'ecoule par la gravite, vers le bas, au travers des ouvertures (4) vers la surface (21); il sort du conduit (17) et passe au travers de la soupape (19) commandee par le detecteur-controleur de niveau de fluide (20) et ensuite au travers du conduit (23) vers la destination desiree. Lorsque le fluide (42) plus dense se deplace vers l'exterieur pour heurter la surface (41), il deplace le melange (43) restant vers l'interieur et le fait continuer le long du chemin (7) courbe du conduit (3) de separation. Le melange restant (43) est soumis a une force centrifuge s'accroissant progressivement produite par un rayon (8) de courbure decroissant du chemin (7) courbe et/ou une zone (6) d'ecoulement decroissant, prise dans le sens de l'ecoulement (9), qui provoque la separation de fluides progressivement plus legers, leur impact contre la surface (41) et leur passage au travers d'orifices comme en (4 ou 30).

Abstract: A method of reinforcing a plastics article or component with metal operates on the principle of heating the metal and then pressing it into the surface of the article, fusing or melting the material on contact. Before the reinforcement is introduced into the plastics, the surface of the plastics is provided with a trench or recess of approximately the form of the metal reinforcement. This recess may be formed in the plastics article or integrally moulded in it. Pref. the dimensions of the recess are such that the plastics material displaced by the reinforcement can be accommodated within the recess. The recess is widened at the top, so that plastics material melted and displaced when the hot reinforcement is placed in the recess can be accommodated on the shoulders of the recess. Used esp. for the prodn. of plastics palettes reinforced with a metal frame or metal members. The method enables the plastics material to be later removed and re-used, esp. in recycling, more easily than was possible by the previous method where the metal frame was pushed into the solid plastics.

Abstract: In a process for producing a mixture of hydrocarbons rich in benzene, toluene and xylene, a fossil fuel is converted to a Fischer-Tropsch synthesis gas containing oxygenated hydrocarbons and the resultant synthesis gas is then converted by Fischer-Tropsch reaction to a product containing oxygenates and hydrocarbons. The Fischer-Tropsch product is then contacted with a catalyst comprising a metal-promoted porous crystalline zeolite having a constraint index within the range of 1 to 12 and a silica to alumina ratio of at least 12 to produce an effluent stream rich in benzene, toluene and xylene. The benzene, toluene and xylene are subsequently removed from said effluent stream.
