Title: Metallurgical tuyere and method of calibrating same
Inventor: FUHRHOP RONALD E
IPC: C21C7/068
Filed: 1988-11-14
Granted: 1993-04-06
Abstract: ABSTRACT OF THE DISCLOSURE A tuyere is disclosed which is adapted for the injection of gases into a metallurgical vessel. The tuyere includes inner and outer concentric tubes having a radial separation therebetween which defines an annular gap.  In use, one gas such as an oxygen mixture flows through the center of the inner tube, and a second normally inert gas flows through the annular gap between the two tubes.  In order to provide a closely predetermined and predictable gas flow rate through the annular gap, an annular groove is formed in the wall of the outer tube which forms an annular restriction in the gap, and the extent of the restriction may be calibrated so as to provide a closely predetermined gas flow rate therethrough when in use.  An annular groove may also be formed in the wall of the inner tube to provide a predetermined restriction in the gas flowing through the inner tube.  The restrictions are positioned adjacent the respective inlet ends of the tubes, so that erosion of the outlet ends does not appreciably effect the gas flow rates through the inner tube and annular gap.  A calibration process is also disclosed, and which assures that all of the tuyeres to be used in a common metallurgical vessel have a closely similar gas flow rate through the annular gap.

Abstract: A protective and decorative polymeric sheet material for bonding to substrates by thermoforming comprises a flexible carrier film, a paint layer on one surface of the carrier film containing a colorant or light reflective flakes or both; and a transparent topcoat overlying the paint layer.  At least a portion of the transparent topcoat is a rubbery cushioning layer formed of a non-crosslinked, or lightly crosslinked polymeric composition of low Tg. The sheet material has an unextended state and is heat softenable to a plastic state in which it is extendable to an extended state at least 50% greater in area than the unextended state.  The paint and topcoat layers have substantially uniform quality and appearance in both the unextended and extended states.  In a preferred embodiment, the thickness of the transparent topcoat is at least 0.1 millimeter. The thick topcoat provides improved retention of gloss and distinctness of image when the sheet material is stretched.  As compared with sheet material of which the topcoat layer consists entirely of crosslinked polymer of relatively high Tg, the sheet material of the invention shows a reduced tendency to peel back from the substrate when cut and subjected to high temperature.

Abstract: Attorney Docket No.:  53.1138 TTL TOTEM POLE ANTI-SIMULTANEOUS CONDUCTION CIRCUIT Abstract An anti-simultaneous conduction transistor is incorporated into the standard TTL circuit totem pole to reduce simultaneous conduction of the pullup and pulldown transistor elements of the totem pole.  The collector of the active discharge anti-simultaneous conduction transistor element (Q5) is operatively coupled to a base of the pullup transistor element (Q2,Q3) through a diode (D5), the emitter is coupled to low potential, and the base is coupled to the base of the pulldown transistor element (Q4) through ballast resistance (R6,R7).  The anti-simultaneous conduction transistor element (Q5) mirrors the conducting state of the pulldown transistor element (Q4) without current hogging substantially diverting or discharging base current from the base of the pullup transistor element (Q2,Q3) whenever the pulldown transistor element (Q4) is conducting.  Undesirable current spikes in the sourcing current are avoided by preventing simultaneous conduction in the totem pole.

Abstract: The invention relates to a resistor element assembly for a glass sheet heating furnace and to a method of replacing a resistor element. A resistor element is built by placing successively in longitudinal direction ceramic elements, with a resistance wire wound therearound. Between the ceramic elements are fitted ceramic spacer blocks whose diameter exceeds that of the resistance wire coils. The resistor element is carried by a support frame upon the spacer blocks. A problem to be resolved is to provide a long resistor element, wherein the major variations in length between the components of various materials caused by major temperature variations do not produce deformations in resistance wires. This problem has been resolved by fitting between one end of the support frame and the corresponding end of the resistor element a tensioned spring which compresses the resistor element at all operating temperatures against a limit stop at the other end of the support frame. The resistor element can be replaced by releasing said spring from the support frame and by pulling the resistor element out of a furnace by utilizing a core pin extending through the entire resistor element, whereby the ceramic elements remain subjected to compression stress. By using an auxiliary spring between the end of said core pin and the end of said resistor element, the compression holding the resistor element together can be maintained also during transportation and installation.

The temperature is recorded simultaneously by two temperature responsive means, one of which is placed in the center of the sample and the other in the immediate vicinity of the vessel wall. The dispersion degree of the graphite phase is assessed in relation to known reference values by aid of recorded values of supercooling at the vessel wall, the recalescence at the vessel wall, the difference between the temperature at the vessel wall and at the centrum of the vessel and the derivative of the temperature decrease at the vessel wall during the time of constant eutectic growth temperature at the center. When necessary a graphite nucleating agent is added to the molten bath or the dispersion is lowered by implementing a holding time prior to casting. The morphology of the graphite precipitation is also determined by aid of recorded values and possibly corrected by changing the amount of structure-modifying agents present.
