Granted: 1999-06-21
Abstract: A method and an apparatus for producing metals and metal alloys from metal oxides in a metallurgical vessel containing a molten bath having a metal layer and a slag layer is disclosed. The method is characterised by injecting a carrier gas and a solid carbonaceous material and/or metal oxides into the molten bath from a side of the vessel that is in contact with the molten bath or from above the molten bath so that the solids penetrate the molten bath and cause molten metal to be projected into the gas space above the molten bath to form a transition zone. The method is also characterised by injecting an oxygen-containing gas into the gas space to post-combust reaction gases released from the molten bath into the transition zone.

Title: Electronic driver for water treatment system UV bulb
Inventor: MARKHAM RONALD C
IPC: H05B41/36
Filed: 1996-07-30
Granted: 2000-06-01
Abstract: A driver or ballast for the ultraviolet bulb of a water treatment system. The driver includes a step-up transformer and a feedback oscillator connected between the secondary and the primary of the transformer. The secondary of the transformer also is selectably connected through one of two different capacitor compensators depending on water flow through the system. In a low intensity mode, the current and the power factor output factor output of the driver are relatively low--preferably just enough to keep the bulb filaments energized. In a high intensity mode, the current and the factor are relatively high to power the bulb at a relatively high efficiency. The driver operates at a relatively low DC voltage. A voltage converter selected as function of the local line voltage converts the AC line voltage to the necessary DC voltage.

Abstract: The present invention provides single spiral land/groove format^s optical disks an optical disk media, optical disk device, and method for tracking an optical disk in which there is no reduction for integer recording density, it is easily and accurately to detect connection point between land and groove in order to switch polarity of tracking servo, and it can correctly employ compensation due to mis-tracking in a short period of time. The present invention is to divide one circle record of the single spiral land/groove format^s optical disk into a integer number of equal sectors in length. Each sector has signal identification section in the beginning area. The signal identification section and another signal identification section of adjacent sector in the same diameter are displaced in the same column. The first part of the signal identification section is shifted from the center of groove to the diameter direction and becomes a reserved placement. The second part of the signal identification section is shifted from the center of groove to the opposite direction and becomes a reserved placement. From the above identification signal placement, connection point between land and groove can be detected, switching polarity can also be detected to employ steady tracking motion, and thus sector formation makes single spiral land/groove format^s optical disks possible.
