Title: Method for reducing dissolved oxygen and carbon contents in molten steel
Inventor: SCHLICHTING MARK R
IPC: C21C7/10
Filed: 1988-11-23
Granted: 1992-08-04
Abstract: ABSTRACT            "METHOD FOR REDUCING DISSOLVED OXYGEN AND CARBON CONTENTS IN MOLTEN STEEL      The carbon and dissolved oxygen contents of molten steel are reduced by a vacuum degassing treatment which may employ oxygen blowing.  A determination is made of the idealized trajectory or path reflecting the change in carbon content and dissolved oxygen content, between atmospheric pressure and a preselected sub-atmospheric pressure at which the vacuum degassing treatment occurs. The idealized trajectory also reflects the effect of extraneous factors on the carbon content, dissolved oxygen content and temperature of the molten steel during the treatment.  A selection is made of the boundaries of the idealized trajectory based upon the permissible limits of carbon content, dissolved oxygen content and temperature at the end of the vacuum degassing treatment.  Adjustments are made at the beginning of the treatment and periodically throughout the treatment to maintain all three parameters, carbon content, dissolved oxygen content and temperature, within the boundaries of the idealized trajectory.  The adjustments employ procedures extraneous to the vacuum degassing treatment.

Title: Rotating ring game

Granted: 1991-09-03
Abstract: Abstract of the Disclosure A two player game provides an assembly of compo-nents in modifiable form by the rotation and sliding of two handles, the handles being separated by a series of spaced individually rotatable game rings, each ring being covered with a unique pattern of selected indicia about its circumference.  Means controlled by the handles permit the players to rotate selected rings to align selected indicia on adjacent rings.  Spacer rings rigidly affixed to a center shaft separate the game rings and have struc-ture interlocking them to each other within the neighbor-ing game rings.  The game rings have inwardly facing teeth which can be selectively actuated by a tab on the end of a handle extension when the handle is rotated.  A series of cooperating spring clips held by portions of the spacer rings in engagement with and beneath said teeth, yieldingly resist turning of the game ring by the tab and a keyway in the handle guard limits rotation of the handle extension at each play to turn the game wheel only one step at a time.  Ridges defined by internal structure of the spacer rings cooperate with projections on the ends of the handle extensions to index the movements of the exten-sion to locate the actuating tab within a selected game ring.

Electronic ballast system (10) includes a filter circuit coupled to an AC power mains (100,110) for substantially suppressing spurious signals passing into or from the power source. The filter circuit is coupled to a regulated switching power supply circuit (14) which generates a regulated boost voltage and draws a substantially constant in phase sinusoidal load current from the power source supplied to a switching circuit (16) which generates a regulated pulsating current at a predetermined frequency. Responsive to the regulated pulsating current a high voltage is induced in the primary windings (1710 and 1680) of induction transformer (T3). The high voltage is coupled to gas discharge lamp (1900) by means of the magnetic coupling between primary winding (1730) and secondary winding (1770) of the output transformer (T2).

The common switching means samples the input cell streams at a frequency at least equal to the sum of the time slot frequencies of the time frames of the input cell streams.  The time frames of the input and output cell streams are phase synchronous and the sampling of the input cell streams is performed in a predetermined order.  The cells of the resultant (STM/ATM) cell stream are supplied to the transmitter circuits in function of their destination.
