Title: Porous refractory element and its manufacturing method
Inventor: GROSJEAN JEAN-CLAUDE
IPC: C21C7/072
Filed: 1980-12-02
Granted: 1983-12-29
Abstract: A device for blowing gas under pressure into a bath of liquid metal comprises a mass of refractory material which is porous at least at an inner portion thereof and placed into a metallic container constituted by an outer metallic envelope closed at one of the ends thereof by a bottom member through a central portion of which a conduit extends for feeding a gas under pressure to the porous inner portion of the mass. A deflector is provided fluid-tightly connected to the bottom inwardly of the envelope in which the wall of the deflector extends parallel to that of the envelope but short of the length of the latter. This permits, on the one hand, to avoid penetration of liquid metal between the envelope and the mass of refractory material to a point where it would block the gas feeding conduit and, on the other hand, to canalize the gas through the porous portion of the mass. The present invention relates likewise to a method of making the above device.

Granted: 1984-04-12
Abstract: Processes and apparatus for the mechanical separation of a combination of meat and bone into useful fractions, the combination being conveyed by a screw (48) of new cross-section profile through a screen (64), which comprises a portion of an elongated cylindrical conduit, softer components, i.e. the meat, being expressed through the screen (64), while harder components, i.e. the bone, are contained by the screen and fed out of the conduit. The screen (64) is constituted by alternate flat and configured annular discs, the latter providing the necessary large plurality of small apertures through which the softer components can be expressed. The screw (48) is designed to develop a radially-outward pulsing action of the combination against the interior wall of the screen to produce the desired separation at a lower pressure than with prior art apparatus and minimisation of shear of the combination against the screen interior wall. The apparatus is provided with a spring controlled throat that permits automatic control of the pressure applied to the separating combination of meat and bone, and that also permits adjustment of that pressure to suit the type of meat in the combination that is being separated.

Title: Needle probe for recording po2 histograms
Inventor: SORGER PETER
IPC: A61B5/00
Filed: 1983-09-01
Granted: 1987-01-22
Abstract: A device for the determination of pO2-histograms in living tissues comprises a macroprobe (111) with a large diameter which is introduced in discrete measurement locations (211, 212) spaced apart by a distance approximately of the size of the probe diameter and at a speed substantially higher than the rate of modification of pO2 of the tissue. The measurement values are determined after a short time interval after the probe has been brought to a standstill. Consequently, said procedure avoids that perturbations of pO2 of the tissues caused by compression effects of the thick probe falsify the measurement value, yet using a thick and resistant probe. A polarographic measuring point usable with this invention and presenting a ring-shaped metal film electrode (54) is characterized particularly in that it comprises a metal ring surface embedded under the measuring point surface, thereby enabling to obtain a measuring point with a very high response speed and a reduced stirring effect.

Abstract: An integrated dynamic write-read memory includes at least one redundant row and/or column initially excluded from normal operation of the memory but available for normal operation as a replacement. At least one row decoder is connected to the memory matrix and at least one column decoder is connected to the memory matrix for addressing. A column address pulse is fed to the memory matrix for initiating addressing by matrix columns and a row address pulse is fed to the memory matrix for initiating addressing by matrix rows. A normal data path leading out of the memory matrix includes a tristate output connected to the normal data path and actuated by addressing with the stored digital data. Another decoder is connected in the normal data path between the memory matrix and the tristate output with an output connected to the tristate output. The other decoder blocks the normal data path from the memory matrix to the tristate output upon addressing each row or column of the portion of the memory matrix intended for normal operation replaced by a redundant row or column and upon simultaneous external activation of the other decoder. The other decoder also indicates the insertion of a redundant row or column in place of a row or column in the portion of the memory matrix intended for normal operation with the appearance of a uniform indicating signal at the data output.

Title: Winding apparatus
Inventor: HUEMER FRANZ X
IPC: B65H59/38
Filed: 1985-08-10
Granted: 1988-06-16
Abstract: The winding equipment for winding yarn, tape or wire-shaped material comprises a bobbin shaft carrying a rotatably fixed armature plate, which is in magnetic, adjustable driving connection with a plate carrying permanent magnets and fixed on the shaft of the driving motor, the adjustment thereof resulting by a thread tension regulating device with a dancing arm carrying a dancing roller. In this connection, the motor or the shaft thereof carrying the permanent magnet plate is supported relative to the bobbin shaft carrying the armature plate radially displaceable as a function of the rotating motion of the dancing arm on the frame of the winding equipment. Owing to this radial displacement of the plates generating the driving connection, relative to each other, not only is the induced magnetic field changed in the simplest manner, but, in addition, the two plates can be arranged with the slightest air gap between each other, which, accordingly, allows for the utilization of small permanent magnets to secure a sufficient magnetic driving connection between the two plates.
