Patent RU-94043760-A (RU)
Inventor: PALENKO A I
IPC: C22B21/06
Filed: 1994-12-14
Abstract: FIELD: nonferrous metallurgy. SUBSTANCE: invention relates to refining aluminium smelts from admixtures, such as alkali metals, hydrogen, and nonmetallic inclusions. Objective of invention is to increase degree of refinement of aluminium smelts and to reduce duration of refinement process owing to fuller utilization of gas and flux treatment of smelt and creation of most favorable conditions for filtration. Objective is achieved by that, in a known method for refining aluminium and its alloys including treatment of smelt with flux, blowing with gas, and filtration, flux and gas are entered simultaneously under smelt level at ratio (6-15):1. In this case, filtration is carried out in conditions of laminar metal flow with velocity of metal flow on filter outlet not exceeding 0.001 m/s. When the method is used, combined feed of gas and flux eliminate probability of enveloping gas-flux bubbles with oxide film and, when continuously entering mix under smelt level, promote fuller and stable utilization of gas-flux mix for refinement from admixtures owing both to absence of oxide film on bubble surface and to constancy of make up of mix being entered. In addition, sufficient remoteness of bubbling zone from filter surface promotes extinguishing of turbulency in moving smelt flow and its coming up to filter surface with flow velocity corresponding to laminar mode of movement, which does not disturb cake layer composed of retained inclusions. Refinement degree of melt is increased in average: by 20% in respect to hydrogen, by 25% in respect to sodium, and by 20 in respect to alumina (fine inclusions). Refinement time is 1.5 times reduced in the case of nitrogen-carnallite mixture utilization, 2 times with mixture nitrogen + (NaCl+KCl+NaAlF), and more than 2 times with hexachloran utilization. EFFECT: increased degree of refinement.

Title: Method for joining optical glasses
Inventor: JIAN BI-YAU
IPC: C03C27/06
Filed: 2003-04-15
Abstract: A method for joining optical glasses uses the molecular attraction force of the optical glass per se to adjust the joining face of the glass to suitable conditions. Next, a stress is applied so that two optical glasses are joined together by the van der Wall force. Furthermore, during the joining process for glasses, a heating procedure is used to reduce the joining time and reinforce the bonding performance. Thus, the present invention uses the molecular attraction force to produce a tight bonding between two panes of glass without the use of any medium.
