Patent DE-2964712-D1 (DE)
Title: Mold assembly and method for continuous casting of metallic strands at exceptionally high speeds
Inventor: BOWER TERRY FREDERICK
IPC: B22D11/00
Filed: 1979-07-19
Granted: 1983-03-17
Abstract: A cooled mold assembly for the continuous, high-speed casting of metallic strands, especially upcasting strands of copper alloys such as brass, has a hollow die in fluid communication with a melt typically held in a casting furnace. A coolerbody surrounds the die in a tight-fitting relationship to form a solidification front in the melt as it advances through the casting zone of the die. The die is preferably slip fit in the coolerbody. A shoulder on the die engages a lower face of the coolerbody and together with a small irregularity on the upper coolerbody wall prevents an axial movement of the die before it thermally expands against the coolerbody. An insulating member located between the die and the coolerbody and below the solidification front fixes the location of that front within a dimensionally uniform area of the die. The insulating member is preferably a ring of a material such as cast silica that has a low coefficient of thermal expansion, a low porosity, and is highly resistant to thermal shock. The insulating member also preferably creates a steep longitudinal temperature gradient at its upper end to promote a high cooling rate over a relatively short casting zone. An insulating hat substantially encloses the coolerbody allowing it to be immersed in the melt and preferably deeply immersed to a level above the casting zone. This mold assembly is preferably used in conjuction with apparatus for drawing the casting through the die in a cycled pattern of forward and reverse strokes characterized by a low frequency, long forward strokes, a high forward velocity and high forward and reverse accelerations.

Title: Process for the recovery of uranium present in impure phosphoric acid
Inventor: PAUTROT JEAN-MARC
IPC: C22B60/02
Filed: 1980-02-22
Granted: 1983-05-11
Abstract: The invention concerns a process for the recovery of the uranium contained in an impure phosphoric acid. The impure acid is treated with an organic phase capable of extracting U (VI), and the resultant organic phase is then re-extracted with an aqueous solution containing complexing acid and an oxidizing-reducing agent in the reduced state, said oxidizing-reducing agent being capable of reducing U+6 to U+4 in said aqueous solution. The resultant aqueous phase is then subjected to electrochemical oxidation, followed by extraction with a second organic phase from which the uranium is recovered, the depleted aqueous solution being recycled to the re-extraction after electrochemical reduction, with the process comprising two organic phase cycles and a cycle of a complexing aqueous solution. The process is of particular interest when applied to the recovery and concentration of uranium contained in a wet process phosphoric acid.

Title: Methods of prestressing tubular apparatus
Inventor: REED STUART E
IPC: B21C37/15
Filed: 1983-08-31
Granted: 1987-01-02
Abstract: A tubular apparatus is assembled from inner and outer tubes or tubulars (14,12) which are connected at spaced locations (16,18) along their length. After heat treatment and other processing steps, either the inner or outer tube (14,12) is heated to reduce its yield strength and then stretched beyond its yield point but not beyond the yield point of the other tubular. The heat source is removed so that the stretched state is maintained. The tubular apparatus is thus prestressed with the inner tubular (14) under compressive prestressing when the inner tubular (14) has been heated and stretched, and the inner tubular (14) under tensile prestressing when the outer tubular (12) has been heated and stretched.

Patent DE-3382416-D1 (DE)
Inventor: LOPEZ DE ROMANA EDUARDO AGUSTI
IPC: G11B7/12
Filed: 1983-08-04
Granted: 1991-10-31
Abstract: The present invention relates to a method and means for monitoring the focussing condition of the writing light beam impinging the writing surface of a recording medium. Systems for monitoring the focus condition of a light beam used in reproducing prerecorded information from a videodisc by a videodisc player operate by splitting off reflected light from the incident light beam path in a region where the incident beam is diverging. In this manner, the reflected beam entering the polarizing cube, placed in the diverging portion of the incident beam, produces a converging light beam diverted to the photodetector. Because of numerous problems in attempting to apply player concepts to writing machine, it has been common practice in the prior art of recording laser discs to periodically determine optimum focussing position for the various optical elements affecting focus by producing a series of test discs and playing back each disc or portion thereof corresponding to a particular combination of settings for the various optical parameters such as power and focus involved. The empirically derived conditions necessary to produce acceptable focussing conditions, however, are extremely costly due to the labor time involved in setting up and determining the optimum focus conditions as well as in the loss of videodisc production due to down time of the mastering machine. The present invention operates on the recognition of the fact that, although for all practical purposes a light beam from a laser device is collimated, it, in fact, is very slightly divergent as it emerges from the laser resulting from diffraction of the Gaussian intensity profile plane wave that exists between the laser resonator mirrors at the beam waist and from refraction as the output light traverses the thickness of the output mirror. Accordingly, since the beam exiting the laser tube is slightly divergent, the reflected light from the videodisc, even though a small in intensity, is conversely (provided the system is in focus) convergent as it passes in reverse direction through the diverging lens and on toward the output of the laser device and beyond to the conjugate point where it forms a real image of the source plane wave, thus eliminating the need for a relay lens. The present invention makes use of this slight divergence and convergence of the incident and reflected beams, respectively, at the exit end of the modulator to effect monitoring of the focus condition of the writing beam.

Granted: 1988-02-11
Abstract: A process for circulating solid particles within a fluidization chamber, in which is formed a circulating fluidized bed comprising a dense lower zone (A) with a high concentration of particles, above which is located a dilute zone (B) containing particles carried along by the rising stream of a gas towards the upper part of the chamber (1), the latter opening into a circuit (4) for discharging the gases and particles, incorporating a device (41) for recovering the particles carried along, which is connected to the chamber (1) by means of a circuit (45) for recycling the recovered particles. In the upper part (12) of the fluidization chamber, the circulation speed of the cases is reduced before their discharge, so as to produce above the dilute zone (B) an upper zone (C) with a higher concentration of particles, in which some (35) of the particles escape from the stream of gas and fall in a shower along the side wall of the chamber, at the same time forming a descending annular film (34). The improved fluidization chamber for carrying out the process applies particularly to the combustion and/or gasification of combustible material.
