Title: Method to produce hypereutetic aluminum-silicon alloys
Inventor: LISAJ VITALIJ E
IPC: C22C1/02
Filed: 1993-01-12
Granted: 1995-05-10
Abstract: FIELD: aluminum-silicon manufacturing. SUBSTANCE: melt alloying by silicon is performed in two stages: first silicon at 1350 - 1650 C is introduced in molten aluminum or its alloy with concurrent melt bubbling and cooling with inert gas down to a temperature of 40 to 100 C above liquidus temperature of the produced alloy, then dust-like crystalline silicon in the amount of 5 to 16 per cent of total weight of silicon being introduced, is introduced by a jet of inert gas. Alloy strength increases by 17 per cent, ductility increases by 22 per cent at the expense of modifying its structure in the second stage. Uniformity of chemical composition of the alloy is increased, gas content is decreased by a factor of 1.2. Time to prepare the alloy decreases by 24 per cent, that allows one to perform productivity of melting/delivering plant, and increase alloy cost price at the expense of it. That is why dust-like silicon is used to alloy and modify the alloy. The dust-like silicon is a waste of aluminum/silicon alloy manufacturing. EFFECT: increased quality of the alloy at the expense of producing unified chemical composition, and comminuting primary silicon crystals, melt duration reducing of melting process and reducing cost price of the alloy. 2 cl, 1 tbl

Granted: 1997-04-10
Abstract: FIELD: electrical engineering; various communication apparatuses with electromagnetic call systems, including telephone sets, for protection against voice information leakage. SUBSTANCE: electrodes are made in the form of metal cones with angles at vertex smaller than or equal to 45 deg and base circle diameter D=L(0.2-1.0) placed in neon gas with their vertices facing each other at distance L=D(0.2-1.0) which opens the circuit for AC signals of amplitudes up to 1 V in voice frequency range; for AC signals of 120 V, 25 Hz, mentioned gap between electrodes is shorted out since when electrodes are placed at voltage higher than 60 V, neon gas is ionized (starts glowing) and in this state it is conductive. Attenuation of AC signals in voice frequency range with amplitudes lower than 1 V depends on angle at vertex of cone, distance between vertices of cones, base circle diameter of cone, and may amount to 70-100 dB and higher still. Such attenuation of signals in voice frequency range prevents passage of signals with amplitude up to 1 V and provides for passing signals with amplitudes over 60 V, such as call signal of 120 V, 25 Hz to telephone set practically without loss. EFFECT: improved reliability of protection of communication lines.
