Patent BR-0313843-A (BR)
Inventor: LIANG DANIEL DONG
IPC: B22D11/06
Filed: 2003-08-27
Abstract: A process for the production of magnesium alloy strip, by twin roll casting, includes the steps of passing molten alloy from a source of supply to a feeding device; feeding the alloy from the feeding device through an elongate outlet of a nozzle and a pair of substantially parallel rolls spaced to define a bite therebetween; rotating said rolls whereby alloy is drawn from the chamber through the bite; and flowing coolant fluid through each roll and thereby cool alloy received in the chamber by heat energy extraction by the rolls whereby substantially complete solidification of the alloy is achieved in the chamber prior to alloy passing through the bite as hot rolled alloy strip. Alloy is held at the source at a temperature sufficient to maintain alloy in the feed device at a superheated temperature; a depth of molten alloy is maintained in the feed device at from about 5 mm to about 22 mm above a centerline of the bite in a plane containing the axes of the rolls; and heat energy extraction by the cooled rolls is maintained at a level sufficient to maintain alloy strip issuing from the bite at a surface temperature below about 400° C.; whereby the hot rolled alloy strip is substantially free of cracks and has good surface quality.

Abstract: The spout seal for combipacks consists of a bottom part ( 2 ) and a hinged lid ( 1 ) attached to it for opening and closing the seal. The bottom part ( 2 ) is fused onto a combipack with its level bottom side. It has a circular, upward-projecting overhang ( 11 ), which forms a pouring spout. The inside of the overhang ( 11 ) is open. The lid ( 1 ) forms a mold ( 21 ) that bulges out upwards on it when swiveled open, which forms a level top side that form-fits into the clearance opening ( 9 ) surrounded by the projecting lip ( 11 ) in the bottom side of the bottom part ( 2 ) when swiveled shut. This level top side either lies flush with this bottom side of the bottom part ( 2 ) or projects downward from this bottom side by up to 0.5 mm. This top side of the bulge ( 21 ) is bonded with the punched-out spot in the combipack or fused with the sealing foil of a combipack exposed through punching. When swiveling the lid ( 1 ) open, the sealing foil is cleanly torn out in the entire clearance section of the bottom part ( 2 ).

Abstract: in a regenerative rotodynamic machine, a portion of a disc-like impeller (11) adjacentthe impeller periphery extends radially through an annular chamber (<sub>1</sub>3) in the machine casing concentric with the impeller (17), thereby dividing said chamber into two annular side channels (13A, 13B) one on each side of the impeller. The portion of the impeller lying in the annular chamber has scooped out annular cavities or recesses in its sides in which are disposed rings of aerodynamic blades (18) and fluid flow passing around the annular chamber from an inlet to an outlet is caused to circulate repeatedly, flowing radially outward through the blading in the impeller cavities and radially inward in the annular side channels alongside the impeller outside the impeller cavities. The aerodynamic blades (18) are designed so that the angle between the entry and exit flows of each blade is greater than 90°.

Abstract: Electro-optical focus detection apparatus for providing a signal indicative of the magnitude and polarity of focus error in a light beam impinging on a surface, such as a recording surface in a recording or playback system. The detector includes a beam splitter for dividing the beam reflected from the recording surface into two reflected beams of equal power, and includes an aperture placed in the path of the two reflected beams. The first reflected beam converges at a focal point before encountering the aperture and the second reflected beam converges at a focal point after encountering the aperture, both beams thereafter impinging upon separate photodetector elements. The aperture reduces the light incident on the photodetectors from both reflected beams, and the apparatus is so configured that the powers of the reflected beams incident on the photodetector elements are identical when the original beam is in focus on the recording surface. When the original beam moves out of focus with the recording surface, both focal points of the reflected beams move in the same direction, to provide an increase in the light falling on one of the photodetector elements and a decrease in light falling on the other, such that the differential output derived from the photodetector elements provides a signal indicative of the magnitude and polarity of the focus error.

Abstract: A considerable portion of the gas developed by fermentation in an anaerobic purification equipment for waste water, together with buoyant sludge, is collected by at least one additional collecting system (5), before it may reach the upper part of the reactor. This additional collecting system is fitted at a distance below the collecting system (6) fitted as usual just below the level of one or more overflow gutters (3; 23) for purified water. The additional collecting system (5) has a hydraulic link with one or more rising pipes (7, 7', 27, 32,31) for raising the liquid sludge mixture by gas lift action. The rising pipes discharge into a separation device (8) from which one or more downpipes (9; 29) for returning separated liquid and sludge extend to the lower section of the reactor chamber. As a result of the tranquility at the top and the turbulence near the bottom, a substantial increase of the load capacity of the equipment can be obtained.
