Patent IT-1189219-B (IT)
Inventor: JOHN MARK MICHAELS
IPC: B01D65/10
Filed: 1982-02-05
Granted: 1988-01-28
Abstract: A membrane pack is constructed, which includes a highly porous carrier sandwiched between a pair of membrane structures that must be kept continuously wet, the pack having a hole and being sealed around the hole to prevent the passage of polluting liquid lying in the hole, into the porous carrier of the pack. The membrane pack is constructed by impregnating the carrier with a flowable polymer which can solidify, to leave a thin layer of the polymer on either surface of the carrier, and by then welding the polymer layers to membranes at either face of the carrier. Ultrasonic welding of the membrane structures to the carrier is performed while the membrane structures are wet, the ultrasonic welding dissipating moisture lying at the interface between the carrier and membrane structures to permit even hydrophilic polymers to be utilized.

Title: Gas burner with safety cut=out
Inventor: KEE HEU-TAE
IPC: F23D/
Filed: 1989-08-03
Granted: 1991-12-18
Abstract: The gas/air mixture is passed through a venturi section (6) after the mixing chamber (3) to impart a fast speed onto mixture, out of the jets (4). A thermal sensor (7) at the base of the flame monitors the flame temperature. If the mixture is short of oxygen the flame lifts off the gas jet and the sensor cools. A safety cut-out shuts off the gas feed. The sensor can be a simple thermocouple linked to the safety cut-out. The venturi is formed by pressing inwards the sides of the gas duct. The venturi directs the mixture onto a V-shaped section (9) splitting the feed to the rows of gas jets.

Inventor: BATSCHVAROV NIKOLA CHRISTOV
IPC: C04B/
Filed: 1980-05-08
Granted: 1986-11-05
Abstract: Liquefier for inorganic binders is made by (1) sulphoration of phenol with 1.01-1.10 mol. core H2SO4 or oleum at 100-150 degrees C for 30 mins., (2) addn. of 0.65-0.80 mol. formalin with cooling to maintain 100 degrees C for 30 mins. (3) neutralisation to pH 7-8 with alkali hydroxide, and (4) diluting with water to a working concn. of 20% solids, giving a product with density 1.11 and viscosity 5-10s. by WS-4. Used as super-liquefier in concrete and mortor to reduce water addition and give self-levelling and compacting properties. Prepn. is by a simplified and accelerated one-stage process which utilises the exothermic heat of reaction. The product causes acceleration of the setting of concrete instead of the usual retardation and eliminates the need for modifiers, e.g. polyols, to speed up setting. Higher quantities can be used, giving improved performance.

Title: Recovery of components of slurries produced during metal milling - using filtration, solvent extraction and magnetic separation techniques
Inventor: TARICCO STEFANO
IPC: C21C/
Filed: 1978-03-10
Granted: 1986-01-13
Abstract: The slurries consist of metallic fragments, abrasive particles and an oily liq. used as a cooling agent during the milling. The process consists of mechanically separating the liq. from the solids by compression between two rollers; treating the solid with a solvent to clean away any residual oil; heating the solid in a reducing atmosphere and separating the ferrous from the nonferrous particles magnetically. The process enables the vast quantities of these slurries which are produced each day in industry to be treated so that the oil can be recycled and the metal particles used in the metallurgical industry. Pollution resulting from disposal of the slurries is avoided.

Abstract: The invention relates to a process for continous copper smelting. The apparatus for carrying out the process includes a smelting furnace (1), a separating furnace (2), a converting furnace (3) and melt launders (7A; 7B) for connecting the smelting furnace, the separating furnace and the converting furnace in series, and a plurality of anode furnaces (4) and blister copper launders (11A; 11B) for connecting the converting furnace (3) and the anode furnaces (4). The copper concentrate is introduced in the smelting furnace (1) and melted and oxidized into a mixture of matte and slag. The mixture is received in the separating furnace (2) and the matte is separated from the slag. Subsequently, the matte separated from the slag is oxidized to produce blister copper. The blister copper is then caused to flow through the blister copper launders (11A; 11B) into one of the anode furnaces (4), and refined into copper of higher quality in the anode furnace (4). In the refining operation at the anode furnace (4), the receiving step and the oxidizing step are carried out at least partly in an overlapping manner. <IMAGE>
