Abstract: ABSTRACT       Flash fusing apparatus for fixing toner im-ages to copy substrates.  The apparatus is characterized by the provision of a power supply and control for a flash lamp which produces multiple flashes which are coupled to a discrete portion of a copy substrate.  Each individual flash is insufficient to effect fusing of the toner images, however, a predetermined number of flashes impinging on the same discrete portion of a copy substrate will effect coalescence of the toner after which cooling of the toner takes place resulting in fixing thereof to the substrate.

Abstract: ABSTRACT OF THE DISCLOSURE              A process for the direct production of steel from particulate iron oxides or concentrates including two major steps in which in Step (1) the iron oxides are converted to iron carbide and in Step (2) steel is produced directly from the carbide in the basic oxygen furnace or the electric furnace.  In the production of the carbide the oxides are reduced and carburized in a single operation using a mixture of hydrogen as a reducing agent and carbon bearing substances such as propane primarily as carburizing agents.  Iron carbide thus produced is introduced as all or part of the charge into a basic oxygen furnace to produce steel directly without the blast furnace step.  In order to make the steel making process auto-thermal, heat is supplied either by using the hot iron carbide from Step (1) or preheating the iron carbide or by in-cluding sufficient fuel in the iron carbide to supply the required heat by combustion.  This divisional application is particularly directed to a process of making steel from iron carbide in the basic oxygen furnace which comprises adding pig iron to the iron carbide charge and controlling the temperature of the charge by the addition of iron carbide.

Abstract: ABSTRACT OF THE DISCLOSURE          Programmable power supplies are made responsive to beam-index and timing signals in order to automatically control the size and position of the display on a  cathode ray tube. The high voltage power supply is also made programmable, re-sponsive to video signal content, to reduce the energy stored in the high voltage circuits.  Savings in energy consumption are also obtained by efficiently modulating the target screen of a beam-index type color cathode ray tube.  Energy lost at the target screen is less than 10% compared to approximately 70% for a conventional color tube, an improvement factor of 7:1 or more.

The stylus lifter gently drops a pickup stylus on the cleaner arm occupying the intermediate position as the caddy is further withdrawn from the player.  The latch plate frees the cleaner arm to swing back to a standby position thereof during still further withdrawal of the caddy, thereby passing the cleaner arm underneath the stylus to wipe it clean. The stylus is raised away from the cleaner arm when the caddy is withdrawn from the player.
